Description

Energy storage mechanism for state switching operation of electrical control system

Technical Field

The invention relates to the field of switches, in particular to an energy storage mechanism for state switching operation of an electrical control system.

Background

With the development of the prior art, particularly in a photovoltaic system, a photovoltaic direct current switch is applied to an inverter to control the working states of a plurality of core components. The reliability of the photovoltaic direct current switch is not only related to the good operation of the whole photovoltaic system, but also related to the stable development of the photovoltaic industry.

Problem one: for the free tripping device for the state switching unit of the electric control system in the market at present, when the driving handle (also called a knob) needs to store energy for the tripping device part, the energy storage element in the driving mechanism part is also needed to store energy, so that the torsion moment of the driving handle is larger, and a person is difficult to hold the handle to drive the energy storage, so that the operation of the state switching unit of the electric control system is inconvenient, and the operation difficulty is larger; one solution is to increase the size of the handle to increase the length of the arm of force of the handle, so that the drive mechanism can perform closing energy storage more effort-saving, but the handle occupies a larger space and the manufacturing cost of the handle is higher.

And a second problem: meanwhile, a free tripping device for an electrical control system state switching unit on the market has the characteristic of quick disconnection, but the free tripping function cannot be realized, for example, when an electrical circuit and photovoltaic equipment are overhauled and maintained, if an overhauler needs to electrify the circuit in the overhauling process, a driving handle carries out switching-on operation on the electrical control system state switching unit, when the switching-on is carried out, the inside of an inverter is easy to be abnormal, when the switching-on is abnormal, the free tripping device needs to be immediately controlled to carry out free tripping action on the electrical control system state switching unit, and quick switching-off is completed, but because the handle of the electrical control system state switching unit is manually held, the tripping device cannot carry out switching-off operation on the electrical control system state switching unit at the moment of switching-on, equipment damage and personal safety injury of operators are easy to be caused. That is, the free trip process is limited by the handle, and the free trip function cannot be completed.

Accordingly, there is a need for further improvements in existing energy storage mechanisms for electrical control system state switching operations.

The information disclosed in the background section of the invention is only for enhancement of understanding of the general background of the invention and should not be taken as an acknowledgement or any form of suggestion that this information forms the prior art already known to a person of ordinary skill in the art.

Detailed Description

Reference will now be made in detail to various embodiments of the invention, examples of which are illustrated in the accompanying drawings and described below. While the invention will be described in conjunction with the exemplary embodiments, it will be understood that the present description is not intended to limit the invention to these exemplary embodiments. On the contrary, the invention is intended to cover not only these exemplary embodiments, but also various alternatives, modifications, equivalents and other embodiments, which may be included within the spirit and scope of the invention as defined by the appended claims.

When an element is referred to as being "on" or "over" another element, it can be in contact with the other element or intervening elements may also be present.

Both clockwise and counterclockwise in the embodiments of the present invention are directions when viewing the energy storage mechanism for the state switching operation of the electrical control system from above.

An energy storage mechanism for an electrical control system state switching operation according to an embodiment of the present invention is described below with reference to fig. 1 to 31.

As shown in fig. 1, an energy storage mechanism for a state switching operation of an electrical control system according to an embodiment of the present invention includes: a housing 1, an operating assembly 2, an actuator 3, a latch assembly 4 and an unlocking assembly 5.

The housing 1 is used to carry an operating assembly 2, an actuator 3, a latch assembly 4 and an unlocking assembly 5.

The operating assembly 2 is mounted to the housing 1, the operating assembly 2 comprising an energy storage element 21.

The actuator 3 is connected to an electrical control system state switching unit.

The latch assembly 4 is mounted to the operating assembly 2 or the actuator 3; the energy storage element 21 is connected with the operation assembly 2 and the execution piece 3, the relative position between the operation assembly 2 and the execution piece 3 is changed, so that the energy storage element 21 stores energy, and after the relative position between the operation assembly 2 and the execution piece 3 is changed to a preset position, the operation assembly 2 can be connected with the execution piece 3 through the lock catch assembly 4 to be in a locking state; then, the operation assembly 2 is driven to move along the opposite direction, and the execution piece 3 is driven to move along the same direction, and the operation assembly 2 drives the execution piece 3 to reach the limiting position of the operation assembly 2 limited by the shell 1, so that the execution piece 3 drives the position state of the state switching unit of the electric control system to change.

The unlocking assembly 5 is mounted to the housing 1 or the operating assembly 2 or the actuator 3; the unlocking component 5 can release the locking state between the operating component 2 and the executing component 3 after receiving the trigger signal, so that the energy stored by the energy storage element 21 is released, the operating component 2 cannot move along the direction of the force applied by the energy storage element 21 due to the limitation of the shell 1, and the executing component 3 can move along the direction of the force applied by the energy storage element 21 to the executing component 3 due to the driving of the energy storage element 21 when the energy storage element 21 releases energy, so that the position state of the state switching unit of the driving electric control system is changed again.

According to the embodiment of the invention, the lock catch assembly 4 is unlocked through the unlocking assembly, so that the locking state between the operating assembly 2 and the executing piece 3 is released, the operating assembly 2 is limited by the shell 1 and cannot move along the direction (clockwise) in which the torsion force is applied to the operating assembly by the energy storage element 21, so that the executing piece 3 is not limited by the operating assembly 2 any more and rotates along the other direction (anticlockwise) under the drive of the energy storage element 21, and the state switching unit of the electric control system is executed to perform the opening action, so that the free tripping is realized.

The relative position between the operating component 2 and the executing component 3 can be changed, and the relative position can be the position along the straight line direction, the relative rotation position, or the position change of other paths.

The change here may be to adjust only the operating member 2, to adjust only the actuator 3, or both.

The force applied by the energy storage element 21 to the operating assembly 2 may be a linear force, a rotational force (i.e., a torque), or other types of forces.

The embodiment of the invention rotates the operating assembly 2 in a first direction (anticlockwise direction) so that the energy storage element 21 stores energy, and then rotates the operating assembly 2 in a second direction (clockwise direction) to perform switching-on.

In another embodiment, the operating assembly 2 may be rotated in the second direction (clockwise direction) so that the energy storage element 21 stores energy, and then the operating assembly 2 is rotated in the first direction (counterclockwise direction) to perform closing. The same applies to linear movement or other forms of path position change. That is, the relative position is changed in one direction so that the energy storage element 21 stores energy, and then is changed in the other direction to perform closing.

In an exemplary embodiment, as shown in fig. 1 to 3, the operating member 2 is rotated in a first direction (counterclockwise direction) to change the relative position between the operating member 2 and the actuating member 3, so that the energy storage element 21 stores energy, after the operating member 2 is rotated to a predetermined position with respect to the actuating member 3, the operating member 2 can be connected to the actuating member 3 through the latch member 4 to be in a locked state, and then the operating member 2 is rotated in a second direction (clockwise direction) to rotate the actuating member 3 in the second direction (clockwise direction), and the operating member 2 drives the actuating member 3 to reach a limit position where the operating member 2 is limited by the housing 1, so that the actuating member 3 drives the position state of the state switching unit of the electrical control system to change.

In the exemplary embodiment, the operating member 2 and the actuating member 3 are locked by the locking member 4 so as to be combined into one body and move together, while the energy storage element 21 connecting the operating member 2 and the actuating member 3 stores energy so as to force the relative positions of the operating member 2 and the actuating member 3 to have a moving apart trend or so as to force the relative positions of the operating member 2 and the actuating member 3 to have a moving close trend.

The distance or approach here may be a distance or approach in a straight direction, a distance or approach in a circumferential direction of a contact position of the energy storage element 21 with the operation member 2 (i.e., an energy storage element stop plate 35 of the actuator 3 contacted by the energy storage element first torsion arm 211 of the energy storage element 21 described later) and a contact position of the energy storage element 21 with the actuator 3 (i.e., a drive plate 235 of the drive disc 23 of the operation member 2 contacted by the energy storage element second torsion arm 212 of the energy storage element 21 described later) during the relative rotation, or may be a distance or approach in other forms of paths.

In an exemplary embodiment, as shown in fig. 1, the housing 1 includes a base 11 and a top cover 12, the base 11 and the top cover 12 forming a receiving cavity.

In an exemplary embodiment, as shown in fig. 1, the housing 1 further includes a buffer member 13 disposed on the base 11, and when the energy storage element 21 is released to drive the actuator 3 to rotate in the first direction (counterclockwise direction), the buffer member 13 is capable of buffering and stopping the actuator 3 to limit the rotation of the actuator 3 in the first direction (counterclockwise direction) and to allow the actuator 3 to stay in the opening position.

In an exemplary embodiment, as shown in fig. 3 and 32, the base 11 is provided with a first stopper 14 and a second stopper 15, the first stopper 14 being capable of stopping a latch lever fixing bent plate 231 of a driving disk 23 described later to restrict rotation of the driving disk 23 in a second direction (clockwise direction), and the second stopper 15 being capable of stopping a driving plate 235 of the driving disk 23 described later to restrict rotation of the driving disk 23 in the second direction (clockwise direction). The dual limiting structure of the first and second stop portions 14 and 15 can realize stable limiting.

In fig. 3, the number of the stop portions is 2, and the number of the stop portions can be adjusted according to practical situations, for example, 1, 3 or more.

In an exemplary embodiment, as shown in fig. 25A and 25B, the actuator 3 includes an actuator body 38 having a plate shape, the actuator body 38 having an actuator center hole 33, and the actuator center hole 33 being passed through by a drive shaft 22 to be described later. The actuator body 38 is rotatably mounted within the base 11.

The outer edge of the actuator body 38 has three energy storage element limiting plates extending upward, and the three energy storage element limiting plates are respectively an energy storage element limiting plate 341, an energy storage element limiting plate 342 and an energy storage element limiting plate 343. One of the three energy storage element retention plates 343 is located on a first side of the energy storage element retention plates 341, 342.

The energy storage element limiting plates 341, 342, 343 are used for limiting the position of the energy storage element 21 described later, and prevent the energy storage element 21 from being greatly deviated during the energy storage process.

The outer edge of the actuator body 38 further has an upwardly extending push plate 32, a latch boss 31 and an energy storage element stop plate 35 in sequence, wherein the push plate 32, the latch boss 31 and the energy storage element stop plate 35 are located on the second side of the energy storage element stop plates 341, 342.

The latch boss 31 can be cooperatively locked with a latch groove 412 of a latch lever 41 described later.

The push plate 32 is capable of contacting a stopper 413 of a lock lever 41 in a lock assembly 4 described later and, after the contact, is capable of forcing the lock lever 41 to rotate in a first direction (counterclockwise) about a lock lever fixing shaft 45.

The energy storage element stop plate 35 is intended to cooperate with the buffer 13 such that the actuator 3 is in a stationary state relative to the housing 1. The energy storage element first torsion arm 211 of the energy storage element 21 described later abuts against the energy storage element stopper plate 35 to apply a torsion moment to the energy storage element stopper plate 35 of the actuator 3 in a first direction (counterclockwise direction) to thereby drive the actuator 3 to rotate in the first direction (counterclockwise direction).

The outer edge of the actuator body 38 also has a downwardly extending connection location plate 36, the connection location plate 36 being located between the energy storage element retention plate 343 and the energy storage element retention plate 341.

The connection positioning plate 36 is connected to the electrical control system state switching unit after passing downward from the base 11.

The actuator body 38 further has a deflection torsion spring limiting hole 37, and a deflection torsion spring first torsion arm 251 of the deflection torsion spring 25 described later is inserted into the deflection torsion spring limiting hole 37.

In an exemplary embodiment, as shown in fig. 1, 35 and 36, the unlocking assembly 5 includes an electromagnetic driving element 51, an unlocking lever 52, an unlocking lever return spring 53, and an unlocking lever fixing shaft 54.

An electromagnetic driving element 51 is installed inside the base 11, and the electromagnetic driving element 51 is electrically connected to an external circuit and is capable of receiving a trigger signal of the external circuit. Upon receiving the trigger signal, the electromagnetic drive member 51 can drive the unlocking lever 52 to rotate in a first direction (counterclockwise direction) about the lock lever fixing shaft 45.

As shown in fig. 30, the unlocking lever 52 includes an unlocking lever body 525, the unlocking lever body 525 having an unlocking lever center hole 521, the unlocking lever center hole 521 being passed through by the unlocking lever fixing shaft 54. The unlocking lever 52 is rotatably installed into the base 11 through the unlocking lever fixing shaft 54 (i.e., the rotation center of the unlocking lever 52 is the unlocking lever fixing shaft 54).

The first end of the unlocking lever body 525 has a first extension plate 526 extending downward and an unlocking lever push rod 522 extending from the lower end of the first extension plate 526 in a direction away from the unlocking lever body 525. The unlocking lever push rod 522 is brought close to or in contact with the electromagnetic driving element 51, and can be pushed by the electromagnetic driving element 51. Likewise, the electromagnetic drive element 51 may also be pushed so that the electromagnetic drive element 51 is reset after the unlocking trigger.

The second end of the unlocking lever body 525 has a second extension plate 527 extending downward and an unlocking lever pressing lever 523 extending from the lower end of the second extension plate 527 in a direction away from the unlocking lever body 525. The unlocking lever pressing lever 523 can be close to or in contact with the trip arm 434 of the trip lever 43, and can drive the trip lever 43 to rotate in the second direction (clockwise direction) about the trip lever fixing shaft 46 by pressing the trip arm 434, unlocking the latch assembly 4.

The unlocking lever pressing lever 523 can push the trip arm 434 of the trip lever 43 described later when the unlocking lever 52 rotates in the first direction (counterclockwise direction).

The unlocking lever body 525 has an unlocking lever stopper 528 near the first end, and one end of the unlocking lever return spring 53 abuts against the unlocking lever stopper.

The unlocking lever body 525 has an unlocking lever return boss 524 near the second end. The drive disk 23 described later can push the unlocking lever reset boss 524 when rotated in the first direction (counterclockwise direction) so that the unlocking lever 52 rotates in the second direction (clockwise direction) around the unlocking lever fixed shaft 54 to reset the electromagnetic drive member 51 after unlocking triggering, or can push the unlocking lever reset boss 524 when rotated in the second direction (clockwise direction) so that the unlocking lever 52 rotates in the second direction (clockwise direction) around the unlocking lever fixed shaft 54 to reset the electromagnetic drive member 51 after unlocking triggering.

The unlocking lever return spring 53 serves to provide an elastic supporting force to the unlocking lever 52, to keep the unlocking lever push rod 522 of the unlocking lever 52 in a state of being close to or in contact with the electromagnetic driving element 51, and to prevent the unlocking lever 52 from rotating.

In an exemplary embodiment, as shown in fig. 1, the operating assembly 2 includes an energy storage element 21, a drive shaft 22, a drive disc 23, a sleeve 24, and a deflection torsion spring 25.

The energy storage element 21 is a torsion spring energy storage or a spring curl energy storage.

The energy storage element 21 is fitted over the sleeve 24 and has an energy storage element first torsion arm 211 and an energy storage element second torsion arm 212 extending radially outwardly (see fig. 21 for a fit).

The energy storage element first torsion arm 211 abuts against the energy storage element stop plate 35 of the actuator 3, and the energy storage element first torsion arm 211 is capable of applying a torsion moment to the energy storage element stop plate 35 of the actuator 3 in a first direction (counterclockwise direction) to rotate the actuator 3 about the drive shaft 22 in the first direction (counterclockwise direction).

The energy storage element second torsion arm 212 is abutted against a drive plate 235 of a drive disk 23 described later, and the energy storage element second torsion arm 212 can be twisted under the drive of the drive disk 23 to store energy of the energy storage element 21, while the energy storage element second torsion arm 212 can apply a second-direction (clockwise-direction) torsion moment to the drive plate 235 of the drive disk 23.

The drive shaft 22 passes through the top cover 12, the drive disk 23, the sleeve 24, the deflection torsion spring 25, the actuator center hole 33 of the actuator body 38 of the actuator 3, and the base 11 in this order from top to bottom.

A handle 16 is mounted on top of the drive shaft 22, through which handle 16 a user turns the drive shaft 22 about the axis of the drive shaft 22 itself.

As shown in fig. 1, the drive shaft 22 includes a rotary shaft 221, a pin 222, a seal ring 223, and a retainer ring 224.

As shown in fig. 2, the rotation shaft 221 is a main body structure of the driving shaft 22, and sequentially passes through the top cover 12, the driving disk 23, the sleeve 24, the deflection torsion spring 25, the actuator center hole 33 of the actuator body 38 of the actuator 3, and the base 11 from top to bottom. The shaft 221 is connected to the handle 16 by a pin 222.

As shown in fig. 2, a sealing ring 223 is disposed on the rotating shaft 221 and cooperates with a rotating shaft mounting hole disposed on the top cover 12 to realize a sealing effect between the rotating shaft 221 and the top cover 12. The retainer ring 224 is disposed between the rotating shaft 221 and the base 11, and the retainer ring 224 limits the actuator 3 in the axial direction to limit the downward movement of the actuator 3.

As shown in fig. 22A and 22B, the drive disk 23 includes a plate-like drive disk body 236. The sleeve 24 supports the drive disk 23. The outer edge of the driving disc body 236 has a latch lever fixing bent plate 231 and a trip lever fixing bent plate 232 extending downward. The latch lever fixing bent plate 231 is used to mount the latch lever 41 described later, and the trip lever fixing bent plate 232 is used to mount the trip lever 43 described later.

The drive disk body 236 also has three limit runners 233, a drive disk central aperture 234, and a drive plate 235 extending downwardly from one of the limit runners 233. The drive plate 235 may not extend downward from the limit chute 233, but may extend downward from other locations.

The limit chute 233 has a predetermined length in the circumferential direction, the limit chute 233 has a first limit surface 233A at a first end in the circumferential direction, the limit chute 233 has a second limit surface 233B at a second end in the circumferential direction, and the limit chute 233 extends from the first limit surface 233A to the second limit surface 233B in the first direction (counterclockwise direction) (see fig. 7A for cooperation). The number of the limit sliding grooves 233 may be adjusted according to practical situations, and may be set to any number of 1 to 6, for example.

The sleeve driving boss 242 of the sleeve 24, which will be described later, is inserted into the corresponding limit chute 233, and the sleeve driving boss 242 can slide along the limit chute 233 so that the sleeve 24 can be rotated about the driving shaft 22 by a predetermined angle with respect to the driving disk 23, thereby achieving a handle deflection indication.

The drive disk central bore 234 is for passing the shaft 221 of the drive shaft 22 therethrough.

As the drive plate 235 rotates in the first direction (counterclockwise), the drive plate 235 can push the energy storage element second torsion arm 212 to twist so that the energy storage element 21 stores energy.

The drive disk body 236 also has a yielding chute 237. One of the latch lever torsion spring second torsion arms 422 described later can pass through the giving way groove 237 of the driving disk 23 so that one of the latch lever torsion spring second torsion arms 422 of the latch lever torsion spring 42 slides along the giving way groove 237, thereby avoiding the driving disk 23 from obstructing the torsion of the latch lever torsion spring second torsion arm 422.

The drive disk body 236 also has a drive disk boss 238, and during rotation of the drive disk 23 in a first direction (counterclockwise direction), the drive disk boss 238 can push the unlocking lever return boss 524 such that the unlocking lever 52 rotates about the unlocking lever fixing shaft 54 in a second direction (clockwise direction).

In an exemplary embodiment, as shown in fig. 2, the sleeve 24 is fitted over the rotation shaft 221 of the drive shaft 22, and the sleeve 24 rotates in synchronization with the drive shaft 22.

As shown in fig. 23A, the sleeve 24 has a sleeve central hole 241 penetrating in the vertical direction, the top of the sleeve 24 has three sleeve driving bosses 242, each sleeve driving boss 242 is inserted into a corresponding limit chute 233 of the driving disk 23, and the sleeve driving boss 242 can slide along the limit chute 233, so that the sleeve 24 can rotate a predetermined angle with respect to the driving disk 23 about the axis of the driving shaft 22, thereby realizing the handle deflection indication.

The number of the limit sliding grooves 233 may be adjusted according to practical situations, and may be set to any number of 1 to 6, for example.

As shown in fig. 23B, the bottom of the sleeve 24 has a concave hole 243, a relief groove 244, and a defining groove 245.

The recess 243 is for receiving the deflection torsion spring 25.

The relief slot 244 is adapted to receive a deflection torsion spring first torsion arm 251 (see, for example, fig. 19B) of a deflection torsion spring 25 described later, and the limit slot 245 is adapted to receive a deflection torsion spring second torsion arm 252 (see, for example, fig. 19B) of a deflection torsion spring 25 described later. The relief groove 244 has a predetermined length in the circumferential direction, the relief groove 244 has a first relief end surface 244A at a first end in the circumferential direction, the relief groove 244 has a second relief end surface 244B at a second end in the circumferential direction, the relief groove 244 extends from the first relief end surface 244A to the second relief end surface 244B along the second direction (clockwise) (see fig. 23A and 23B for cooperation), and the deflecting torsion spring first torsion arm 251 of the deflecting torsion spring 25 can slide along the relief groove 244.

As shown in fig. 2, the deflection torsion spring 25 is mounted within the recess 243 of the sleeve 24, as shown in fig. 24, the deflection torsion spring 25 having a deflection torsion spring first torsion arm 251 and a deflection torsion spring second torsion arm 252.

The first torsion arm 251 of the deflection torsion spring is inserted into the deflection torsion spring limiting hole 37 of the actuator body 38 of the actuator 3 after being passed out of the relief groove 244 of the sleeve 24 (see fig. 19A in cooperation).

The setting angle of the abdication groove 244 is larger than the movable range of the first torsion arm 251 of the deflection torsion spring, and a clearance allowance exists, namely, the first torsion arm 251 of the deflection torsion spring cannot be contacted with the first abdication end face 244A and the second abdication end face 244B, so that a movable space exists in the first torsion arm 251 of the deflection torsion spring.

The deflecting torsion spring second torsion arm 252 is inserted into the defined slot 245 of the sleeve 24 and is capable of imparting a torsional moment to the sleeve 24.

As shown in fig. 2, the base 11 supports the actuator 3, the actuator 3 supports the sleeve 24, and the sleeve 24 supports the drive disk 23. The sleeve 24 is capable of transmitting the torque of the drive shaft 22 to the drive disk 23.

As shown in fig. 31, a step 225 is provided on the rotation shaft 221 of the drive shaft 22, the drive disk 23 is provided below the step 225, and the step 225 can restrict the drive disk 23 from moving upward in the axial direction.

The step 225 of the drive shaft 22 and the retainer 224 in combination limit the movement of the actuator 3, the deflecting torsion spring 25, the sleeve 24, and the drive disk 23 in the axial direction.

In the exemplary embodiment, the latch assembly 4 includes a latch portion and a trip portion, and by changing the position state of the latch portion, the connection between the operating assembly 2 and the actuator 3 is realized to be in a locked state, so that the operating assembly 2 and the actuator 3 can move along the same direction, and further the position state of the state switching unit of the electrical control system is driven to change.

Alternatively, the unlocking component 2 changes the position state of the tripping part, so that the locking state of the operating component 2 and the executing piece 3 is released, and the energy storage element 21 releases energy and drives the executing piece 3 to move.

In an exemplary embodiment, as shown in fig. 1, 37 and 38, the latch assembly 4 includes a latch lever 41, a latch lever torsion spring 42, a trip lever 43, a trip lever torsion spring 44, a latch lever fixed shaft 45 and a trip lever fixed shaft 46. The latch lever 41 and the latch lever torsion spring 42 constitute a latch portion, and the trip lever 43 and the trip lever torsion spring 44 constitute a trip portion.

As shown in fig. 4, the latch lever 41 is mounted to the latch lever fixing bent plate 231 through a latch lever fixing shaft 45, and is rotatable about the latch lever fixing shaft 45. As shown in fig. 26A, the latch lever 41 includes a horizontal latch lever upper plate 416, a latch lever lower plate 417, and a vertical latch lever connecting plate 418. The latch bar upper plate 416 is connected to the latch bar lower plate 417 by a latch bar connecting plate 418.

The latch lever upper plate 416 and the latch lever lower plate 417 each have a latch lever limiting hole 411, and the latch lever limiting hole 411 is provided for the latch lever fixing shaft 45 to pass through.

The latch lever lower plate 417 has a stopper plate 413, and the stopper plate 413 can be in contact with the push plate 32 of the actuator 3 and can force the latch lever 41 to rotate in a first direction (counterclockwise direction) about the latch lever fixing shaft 45 after the contact.

The end face of the locking rod connecting plate 418 facing the locking rod limiting hole 411 is provided with a locking groove 412, and the end face of the locking rod connecting plate 418 far away from the locking rod limiting hole 411 is a locking rod supporting surface 414. The latch bar attachment plate 418 also has a latch bar stop surface 415 (see fig. 26B for a fit) facing away from the stop plate 413.

The latching recess 412 can be locked in cooperation with the latching boss 31 of the actuating member 3.

The latch lever abutment surface 414 of the latch lever 41 can be brought into abutment with a trip lever abutment surface 433 of a trip lever lower plate 436 of the trip lever 43 described later, thereby achieving the first locking state.

The latch lever stopper surface 415 of the latch lever 41 can be engaged with a trip lever stopper surface 432 of a trip lever 43 described later to form a holding state.

The lock lever torsion spring 42 is mounted to the lock lever fixed shaft 45, as shown in fig. 27, the lock lever torsion spring 42 has a lock lever torsion spring first torsion arm 421 and two lock lever torsion spring second torsion arms 422.

The latch lever torsion spring first torsion arm 421 abuts against the latch lever fixing bent plate 231.

One of the two latch lever torsion spring second torsion arms 422 abuts against the latch lever upper plate 416 and is inserted into the yield chute 237 of the drive disk 23 and is capable of providing a torsional moment to the latch lever upper plate 416, and the other of the two latch lever torsion spring second torsion arms 422 abuts against the latch lever lower plate 417 and is capable of providing a torsional moment to the latch lever lower plate 417. During rotation of the latch lever 41 about the latch lever fixed axis 45, one of the two latch lever torsion spring second torsion arms 422 of the latch lever torsion spring 42 can slide along the yielding chute 237 of the drive plate 23 to avoid the drive plate 23 from obstructing torsion of one of the two latch lever torsion spring second torsion arms 422 of the latch lever torsion spring 42.

The latch lever torsion spring 42 can apply a torsion moment to the latch lever 41 to cause the latch lever 41 to rotate in the second direction (clockwise direction) or cause the latch lever 41 to have a tendency to rotate in the second direction (clockwise direction).

The trip bar 43 is mounted to the trip bar fixing bent plate 232 (see fig. 33 for cooperation) through the trip bar fixing shaft 46, and is rotatable about the trip bar fixing shaft 46. As shown in fig. 28, the trip bar 43 includes a horizontal trip bar upper plate 435, a trip bar lower plate 436, and a vertical trip bar connecting plate 437. The trip bar upper plate 435 is connected to the trip bar lower plate 436 through a trip bar connecting plate 437. The height of the trip bar upper plate 435 of the trip bar 43 is approximately flush with the height of the latch bar upper plate 416 of the latch bar 41, and the height of the trip bar lower plate 436 of the trip bar 43 is between the height of the latch bar upper plate 416 of the latch bar 41 and the height of the latch bar lower plate 417.

The trip bar upper plate 435 and the trip bar lower plate 436 each have a trip bar limiting aperture 431. The trip bar limiting hole 431 is provided for the trip bar fixing shaft 46 to pass through.

Trip bar lower plate 436 has a trip bar stop surface 432 and a trip bar abutment surface 433.

The trip bar stop surface 432 is configured to cooperate with the latch bar stop surface 415 on the latch bar 41 to form a holding state in which the operating assembly 2 is locked into an interlocking configuration with the actuator 3, i.e., a second locked state, by the latch assembly 4.

The trip lever abutment surface 433 of the trip lever lower plate 436 of the trip lever 43 forms an abutment state with the latch lever abutment surface 414 of the latch lever 41, thereby achieving the second lock state.

Trip bar lower plate 436 also has trip arm 434. When the unlocking lever 52 is rotated in the first direction (counterclockwise direction), the unlocking lever pressing lever 523 of the unlocking lever 52 can push the trip arm 434 of the trip lever 43 so that the trip lever 43 is rotated about the trip lever fixing shaft 46 in the second direction (clockwise direction).

During rotation of the trip bar 43 about the trip bar fixing axis 46 in the second direction (clockwise direction), the trip bar 43 can twist the trip bar torsion spring 44 such that the trip bar torsion spring 44 stores energy.

During rotation of the trip bar 43 about the trip bar fixing shaft 46 in the second direction (clockwise direction), the trip bar 43 can be released from abutment with the lock bar 41.

The trip bar torsion spring 44 is mounted to the trip bar fixed shaft 46, as shown in fig. 29, the trip bar torsion spring 44 has a trip bar torsion spring first torsion arm 441 and a trip bar torsion spring second torsion arm 442.

The trip bar torsion spring first torsion arm 441 abuts against the trip bar fixing bent plate 232, and the trip bar torsion spring second torsion arm 442 abuts against the trip bar connection plate 437 of the trip bar 43, and can apply a torsion moment to the trip bar 43. That is, the trip bar torsion spring 44 can apply a torsion moment to the trip bar 43 to cause the trip bar 43 to rotate in a first direction (counterclockwise direction) or cause the trip bar 43 to have a tendency to rotate in a first direction (counterclockwise direction).

There are two locking states between the actuator 3 and the latch assembly 4:

first locked state:

the trip lever abutment surface 433 of the trip lever lower plate 436 of the trip lever 43 forms an abutment state with the latch lever abutment surface 414 of the latch lever 41 (see fig. 5 for cooperation), i.e., a locked state between the latch lever 41 and the trip lever 43, at which time the latch boss 31 of the actuator 3 is not locked with the latch groove 412 of the latch lever 41.

Second locked state:

the trip bar stop surface 432 of the trip bar lower plate 436 of the trip bar 43 and the latch bar stop surface 415 of the latch bar 41 form a holding state (see fig. 6 and 20, for cooperation), the latch boss 31 of the actuator 3 is located in the latch groove 412 of the latch bar 41, and the latch boss 31 of the actuator 3 is locked with the latch groove 412 of the latch bar 41 (see fig. 12, for cooperation), that is, the locking state among the latch bar 41, the trip bar 43 and the actuator 3 is achieved, so that the actuator 3 can be connected with the operation assembly 2 through the latch assembly 4 to be in the locking state.

The deflection torsion spring 25 has two stored energy states:

one is a reverse torsion (direction of enlargement in the torsion spring) stored energy state in which the deflecting torsion spring first torsion arm 251 and the deflecting torsion spring second torsion arm 252 have a tendency to contract inwardly, i.e., the deflecting torsion spring first torsion arm 251 applies a torsion moment in the second direction (clockwise direction) to the actuator 3, and the deflecting torsion spring second torsion arm 252 of the deflecting torsion spring 25 applies a torsion moment in the first direction (counterclockwise direction) to the sleeve 24.

The other is a clockwise (contracted direction in the torsion spring) stored energy state in which the deflecting torsion spring first torsion arm 251 and the deflecting torsion spring second torsion arm 252 have a tendency to expand outwardly, i.e., the deflecting torsion spring first torsion arm 251 applies a torsion moment in a first direction (counterclockwise direction) to the actuator 3, and the deflecting torsion spring second torsion arm 252 of the deflecting torsion spring 25 applies a torsion moment in a second direction (clockwise direction) to the sleeve 24.

The operation of the energy storage mechanism for the state switching operation of the electrical control system according to the embodiment of the present invention will be described below with reference to the accompanying drawings.

Before the energy storage is rebuckled, the state of the energy storage mechanism for the operation of the electrical control system state switching unit is as shown in fig. 7A, the trip lever abutment surface 433 of the trip lever lower plate 436 of the trip lever 43 forms an abutment state with the latch lever abutment surface 414 of the latch lever 41, and the latch boss 31 of the actuator 3 is not locked with the latch groove 412 of the latch lever 41, i.e., the first locking state. Further, the sleeve driving boss 242 of the sleeve 24 is in contact with the first limit surface 233A. The energy storage element stop plate 35 of the actuator 3 is in contact with the buffer 13 on the base 11, and the actuator 3 is in the opening position state.

The deflecting torsion spring 25 is in a reverse torsion (the direction of expansion in the torsion spring) stored energy state (the stored energy is stored after the end of the free trip process at this time), the deflecting torsion spring first torsion arm 251 is in a position close to the first yielding end face 244A (see fig. 7B for cooperation), and the deflecting torsion spring first torsion arm 251 applies a torsion moment in the second direction (clockwise direction) to the actuator 3, and the deflecting torsion spring second torsion arm 252 of the deflecting torsion spring 25 applies a torsion moment in the first direction (counterclockwise direction) to the sleeve 24 to push the corresponding handle 16 to deflect by a certain angle, i.e., to deflect to the trip position.

The energy storage element 21 is in a pre-tensioned state, the energy storage element first torsion arm 211 of the energy storage element 21 applies a torsion moment in a first direction (counterclockwise) to the energy storage element stop plate 35 of the actuator 3, and the energy storage element second torsion arm 212 of the energy storage element 21 applies a torsion moment in a second direction (clockwise) to the drive plate 235 of the drive disc 23.

In the embodiment of fig. 7A, the indicated direction of the pin 222 is the direction of the handle 16.

And (3) a re-buckling energy storage process:

the handle 16 is manually rotated in a first direction (counter-clockwise) and the handle 16 rotates the drive shaft 22 in the first direction (counter-clockwise) to urge the sleeve 24 to rotate in the first direction (counter-clockwise) and thereby urge the drive disk 23 to rotate in the first direction (counter-clockwise). The drive disk 23 rotates the latch assembly 4 (in the first locked state) together in a first direction (counterclockwise) about the drive shaft 22 (see fig. 7A and 8A for cooperation).

During rotation of the drive disk 23 in the first direction (counterclockwise direction), the drive disk boss 238 of the drive disk 23 is capable of pushing the unlocking lever reset boss 524 of the unlocking lever 52 (see fig. 8A for cooperation) to push the unlocking lever 52 to rotate about the unlocking lever fixing shaft 54 in the first direction (counterclockwise direction), thereby causing the unlocking lever push rod 522 of the unlocking lever 52 to push the electromagnetic drive member 51 of the unlocking assembly 5 to reset the electromagnetic drive member 51 of the unlocking assembly 5 (see fig. 7A, 8A and 9A for cooperation).

During rotation of the drive disc 23 in the first direction (counter-clockwise direction), the drive plate 235 of the drive disc 23 pushes the energy storage element second torsion arm 212 of the energy storage element 21 to twist (see fig. 18 for cooperation), so that the energy storage element 21 stores energy. The energy storage element first torsion arm 211 of the energy storage element 21 applies a torsion moment in a first direction (counterclockwise) to the energy storage element stop plate 35 of the actuator 3, but at this time the energy storage element stop plate 35 of the actuator 3 is restricted by the buffer 13, so that the deflection torsion spring first torsion arm 251 of the deflection torsion spring 25 and the actuator 3 are both in a stationary state with respect to the base 11 of the housing 1.

Continuing to rotate the handle 16 in the first direction (counterclockwise), the drive disk 23 and the latch assembly 4 continue to rotate about the drive shaft 22 in the first direction (counterclockwise), and the drive disk 23 brings the stop plate 413 of the latch lever 41 in the latch assembly 4 into contact with the push plate 32 provided on the actuator 3 (see fig. 10 for cooperation).

Since the actuator 3 is at rest relative to the housing 1 at this time, during continued rotation of the latch assembly 4 about the drive shaft 22 in the first direction (counterclockwise), the push plate 32 of the actuator 3 contacts the stop plate 413 of the latch lever 3 and pushes the stop plate 413 into movement, thereby causing the latch lever 41 in the latch assembly 4 to rotate about the latch lever fixing axis 45 in the first direction (counterclockwise).

During rotation of the latch lever 41 about the latch lever fixing axis 45 in the first direction (counterclockwise direction), the latch lever connecting plate 418 of the latch lever 41 pushes the latch lever torsion spring first torsion arm 421 of the latch lever torsion spring 42 to twist, so that the latch lever torsion spring 42 stores energy, and at the same time, the latch lever abutment surface 414 of the latch lever 41 is no longer abutted against the trip lever abutment surface 433 of the trip lever lower plate 436 of the trip lever 43 (see fig. 10 for cooperation), i.e., the first locking state is released.

As shown in fig. 10 and 11, after the latch lever abutment surface 414 of the latch lever 41 is disengaged from the trip lever abutment surface 433 of the trip lever 43, the latch lever 41 no longer restricts the trip lever 43 from rotating in the first direction (counterclockwise direction).

Under the action of the torsional moment provided by the trip bar torsion spring 44, the trip bar 43 rotates about the trip bar fixing shaft 46 in a first direction (counterclockwise) until the abutment surface 438 of the trip arm 434 of the trip bar 43 contacts the trip bar fixing bent plate 232 of the operating assembly 2 to stop the rotation (see fig. 11 in cooperation).

During rotation of the lock lever 41 about the lock lever fixing shaft 45 in the first direction (counterclockwise direction), the lock lever 43 rotates in the first direction (counterclockwise direction) to a state in which the lock lever stopper surface 415 of the lock lever 41 is brought close to the lock lever stopper surface 432 of the lock lever 43, at which time the lock boss 31 of the actuator 3 passes over and enters the lock recess 412 of the lock lever 41, but the lock boss 31 does not come into contact with the lock recess 412 (see fig. 11).

When the stopper plate 413 of the latch lever 41 is in contact with the latch lever fixing bent plate 231 of the driving disk 23, the latch lever 41 is no longer rotated in the first direction (counterclockwise direction) about the latch lever fixing shaft 45 (see fig. 11 for cooperation), and at this time, the handle 16 is twisted in the first direction (counterclockwise direction) to the limit twist position during the rebuckling energy storage. In fig. 11, the position where the stopper plate 413 of the latch lever 41 contacts the latch lever fixing bent plate 231 of the driving disk 23 is just shielded by the latch lever torsion spring 42.

The handle 16 is released to release the driving force of the driving shaft 22, and thus the driving force of the driving disk 23 is released.

Under the action of the torsional moment provided by the energy storage element 21, the energy storage element first torsion arm 211 of the energy storage element 21 can apply a torsional moment to the drive plate 235 of the drive disk 23 in a second direction (clockwise direction) so that the drive disk 23 rotates in the second direction (clockwise direction) to drive the latch lever 41 to rotate about the drive shaft 22 in the second direction (clockwise direction). When the latch boss 31 is in contact with the latch groove 412 of the latch lever 41 while the trip lever stopper surface 432 is in an abutting state (see fig. 12 for cooperation) with the latch lever stopper surface 415 of the latch lever 41, i.e., in the second locked state, the drive disk 23 stops rotating.

During the rotation of the latch lever 41 around the drive shaft 22 in the second direction (clockwise direction), the push plate 32 of the actuator 3 is away from the stop plate 413 provided on the latch lever 3, the abutment between the push plate 32 and the stop plate 413 is released, and under the combined action of the torsion moment applied by the latch lever torsion spring 42 and the latch boss 31 of the actuator 3, the latch lever 41 rotates around the latch lever fixing shaft 45 in the second direction (clockwise direction) until the latch groove 412 of the latch lever 41 is locked with the latch boss 31 of the actuator 3 (see fig. 11 and 12 in cooperation), and the operation assembly 2 is locked with the actuator 3 into an interlocking structure, i.e., a second locking state, by the latch assembly 4.

In the process of re-buckling and storing energy, the executing piece 3 is limited by the buffer piece 13 to be in a relatively static state relative to the shell 1, and the executing piece 3 does not execute switching action.

After releasing the handle 16, the deflecting torsion spring 25 is in a clockwise state, and under the torsion moment provided by the deflecting torsion spring 25, the sleeve 24 rotates in the second direction (clockwise direction), and the handle 16 is driven to rotate back to the brake-off indication position in the second direction (clockwise direction).

In the rebuckling energy storage process, the specific changes of the deflection torsion spring 25 are as follows:

In the process of re-buckling energy storage, the first torsion arm 251 of the deflection torsion spring 25 connected with the executing piece 3 is a fixed torsion arm, and when the handle 16 rotates by a first preset angle along a first direction (anticlockwise direction), the energy storage moment of the deflection torsion spring 25 is released completely (in any state in fig. 8B to 9B, because the second preset angle is twisted in the process of re-buckling energy storage, the position of the second preset angle about the first limit surface 233A should be deflected in the middle of the abdicating groove 244, and the energy release of the deflection torsion spring is completed).

In the illustrated embodiment, the first preset angle is 40 degrees, but the value thereof may be adjusted according to circumstances, and may be set to any number of 30 degrees to 50 degrees, for example.

In the illustrated embodiment, the second preset angle is 8 degrees, but the value thereof may be adjusted according to circumstances, and may be set to any number of 3 to 15 degrees, for example.

Continuing to rotate the handle 16 in the first direction (counterclockwise direction), the deflecting torsion spring 25 is rotated clockwise (the contracted direction of the torsion springs), that is, the deflecting torsion spring second torsion arm 252 is driven to rotate counterclockwise, so that the deflecting torsion spring 25 stores energy again (clockwise energy storage), at this time, the deflecting torsion spring second torsion arm 252 of the deflecting torsion spring 25 applies a torsion moment rotating in the second direction (clockwise direction) to the sleeve 24, and the deflecting torsion spring first torsion arm 251 of the deflecting torsion spring 25 applies a torsion moment rotating in the first direction (counterclockwise direction) to the actuator 3.

After the energy storage is rebuckled, the second locking state is completed.

When the handle 16 is released and the sleeve 24 is rotated in the second direction (clockwise) by the deflecting torsion spring 25, the sleeve 24 is driven to stop by the sleeve driving boss 242 of the sleeve 24 contacting the second limit surface 233B of the limit runner 233 (see fig. 12 for cooperation), and at this time, the handle 16 is deflected from the over-screwing angle to the opening position, and the corresponding pin 222 of the handle 16 is also deflected from the over-screwing angle to the opening position (see fig. 11 to 12 for cooperation).

Manual closing process:

as shown in fig. 13, when the above-mentioned rebuckling energy storage is completed, the handle 16 is rotated in the second direction (clockwise), and the handle 16 drives the operating component 2 to rotate in the second direction (clockwise), so as to drive the actuator 3 in a locked state to rotate in the second direction (clockwise), and the connection positioning plate 36 of the actuator 3 can perform a closing operation of the state switching unit of the electrical control system. At this time, the latch lever fixing bending plate 231 of the driving disk 23 is restricted by the first stopper portion 14 of the base 11, the driving plate 235 of the driving disk 23 is restricted by the second stopper portion 15 of the base 11, and the driving disk 23 cannot be further rotated in the second direction (clockwise direction).

Manual brake separating process:

As shown in fig. 14, when the above-mentioned closing is completed, the handle 16 is rotated along the first direction (counterclockwise), and the handle 16 drives the operating component 2 to rotate along the first direction (counterclockwise), and can also drive the actuator 3 in a locked state with the operating component to rotate along the first direction (counterclockwise), and the connection positioning plate 36 of the actuator 3 can execute the opening action of the state switching unit of the electrical control system.

During manual closing and opening, the inside of the latch assembly 4 is in the second locked state and the energy storage element 21 is in the energy storage state.

The stored energy torque of the energy storage element 21 is larger than the stored energy torque of the internal energy storage element of the electric control system state switching unit operating mechanism.

Free tripping process:

as shown in fig. 15 and 34, after the above-mentioned closing operation is completed, in some special cases, the electromagnetic driving element 51 of the unlocking assembly 5 is triggered after receiving the unlocking signal to push the unlocking lever push rod 522, so that the unlocking lever 52 rotates in a first direction (counterclockwise direction) about the unlocking lever fixing shaft 54, and further, the unlocking lever push rod 523 of the unlocking lever 52 pushes the trip arm 434 of the trip lever 43 to move, so that the trip lever 43 rotates in a second direction (clockwise direction) about the trip lever fixing shaft 46.

During rotation of the trip bar 43 about the trip bar fixing axis 46 in the second direction (clockwise), the trip bar connecting plate 437 of the trip bar 43 pushes the trip bar torsion spring second torsion arm 442 of the trip bar torsion spring 44 to twist, so that the trip bar torsion spring 44 stores energy. At the same time, the trip lever 43 rotates about the trip lever fixing shaft 46 in the second direction (clockwise direction) to a state in which the latch lever stopper surface 415 of the latch lever 41 is no longer in abutment with the trip lever stopper surface 432 of the trip lever 43, i.e., the second lock state is released (see fig. 15 for cooperation).

After the latch lever stopper surface 415 of the latch lever 41 is no longer in abutment with the trip lever stopper surface 432 of the trip lever 43, the trip lever 43 releases the abutment with the latch lever 41, and the latch lever 41 is no longer restricted from rotating in the second direction (clockwise direction).

Under the action of the torsion moment provided by the latch lever torsion spring 421, the latch lever 41 rotates in the second direction (clockwise) about the latch lever fixing shaft 45 until the latch lever stopper surface 415 on the latch lever 41 comes into contact with the trip lever fixing bent plate 232 to stop the rotation or comes into contact with the trip arm 434 of the trip lever 43, and at the same time, the latch lever abutment surface 414 of the latch lever 41 approaches or abuts against the trip lever abutment surface 433 of the trip lever 43 (see fig. 16 for cooperation). After the unlocking lever 52 is reset, the latch lever abutting surface 414 of the latch lever 41 and the trip lever abutting surface 433 of the trip lever 43 are in a complete abutting state; if the release lever 52 always applies a force to the trip lever 43, the latch lever abutting surface 414 of the latch lever 41 and the trip lever abutting surface 433 of the trip lever 43 may be in a close state or an abutting state.

During the rotation of the latch lever 41 around the latch lever fixing shaft 45 along the second direction (clockwise direction), the latch groove 412 of the latch lever 41 is separated from the latch boss 31 provided on the actuator 3, so that the latch lever 41 no longer limits the rotation of the actuator 3 along the first direction (counterclockwise direction), that is, the latch lever 41 provided on the latch assembly 4 is in the first locking state with the trip lever 43.

The energy storage element first torsion arm 211 of the energy storage element 21 applies a torsion moment to the energy storage element stopper plate 35 of the actuator 3 (the torsion moment is much larger than the torsion moment of the deflection torsion spring 25 and is larger than the stored torsion moment of the internal energy storage element of the electric control system state switching unit operating mechanism), so that the actuator 3 rotates around the driving shaft 22 in a first direction (counterclockwise direction) (see fig. 17 in cooperation), and thus the automatic opening action of the electric control system state switching unit can be performed to realize the free tripping process (i.e., the automatic opening process).

When the actuator 3 rotates in the first direction (counterclockwise direction) to the opening position, it collides with the damper 13 provided on the base 11 and stops (see fig. 17).

During the energy release of the energy storage element 21, a torsion moment is applied to the driving disc 23, which causes the driving disc 23 to have a tendency to rotate in the second direction (clockwise direction), the latch lever fixing bending plate 231 of the driving disc 23 is limited by the first stop portion 14 of the base 11, the driving plate 235 of the driving disc 23 is limited by the second stop portion 15 of the base 11, the driving disc 23 cannot rotate in the first direction (counterclockwise direction), and the driving disc 23 is stationary with respect to the base 11.

After the free tripping, the energy storage element 21 applies a torsion moment in the second direction (clockwise) to the drive disk 23 of the operating assembly 2, the first stop 14 and the second stop 15 of the base 11 of the housing 1 being able to limit the rotation of the drive disk 23 of the operating assembly 2 in the clockwise direction.

Handle deflection indication:

after the trip free procedure, it is also necessary to rotate the handle 16 back to the trip position, i.e., it is necessary to automatically effect the handle deflection indication.

When the switch is in the closed state, the handle 16 is now pointed to the closed position.

When free tripping is carried out, namely, the handle 16 or the rotating shaft is blocked, the free tripping can be realized, and automatic brake separation is completed; when the release handle 16 is locked or the rotation shaft 221 connected to the release handle 16 is locked, the handle 16 cannot be directed to the closing position, and the drive handle 16 needs to be deflected by a certain angle from the closing position to the opening position.

The deflecting torsion spring 25 drives the sleeve 24 to rotate the drive shaft 22 and the handle 16 in a first direction (counterclockwise) to point to the trip position.

Before free tripping, the deflection torsion spring is in an energy storage state (at this time, the energy storage is the energy stored after the rebuckling process is finished).

In the first stage of the free tripping process, the torsion moment applied to the actuating member 3 by the first torsion arm 251 of the deflecting torsion spring is in the first direction (counterclockwise direction), that is, the actuating member 3 is driven to rotate in the first direction (counterclockwise direction), and when the energy storage of the deflecting torsion spring 25 is released, the first stage of the free tripping process is finished.

In a second phase of the free trip process, the actuator 3 drives the first torsion arm 251 of the deflection torsion spring to rotate in a first direction (counterclockwise direction) under the action of the torsion moment provided by the energy storage element 21, so that the deflection torsion spring 25 stores energy again (reverse torsion energy storage). After the energy is stored in the deflection torsion spring 25, the second torsion arm 252 of the deflection torsion spring 25 is connected to the sleeve 24, and the second torsion arm 252 of the deflection torsion spring applies a torsion moment along a first direction (counterclockwise direction) to the sleeve 24, so as to drive the sleeve 24 to rotate along the first direction (counterclockwise direction) within the movable range of the limit chute 233 of the driving disc 23 (i.e., rotate from a position contacting the second limit surface 233B to a position contacting the first limit surface 233A), and further drive the handle 16 to point to the trip position.

Meanwhile, the first torsion arm 251 of the deflection torsion spring 25, which is re-buckled with the stored energy, drives the actuator 3 to rotate a certain angle along the first direction (anticlockwise direction) until the stored energy of the deflection torsion spring 25 is released, and then the energy storage element 21 continues to drive the actuator 3 to rotate along the first direction (anticlockwise direction), so that the actuator 3 continues to drive the first torsion arm 251 of the deflection torsion spring to rotate in turn along the first direction (anticlockwise direction), and the deflection torsion spring 25 is driven to twist the stored energy again (reverse torsion stored energy), so that the second torsion arm 252 of the deflection torsion spring 25 applies a torsion moment along the first direction (anticlockwise direction) to the sleeve 24.

Before the rebuckling energy storage process starts, the state of the deflection torsion spring 25 is the reverse torsion energy storage (the energy stored in the free tripping process), and in the rebuckling energy storage process, the deflection torsion spring 25 releases energy from the reverse torsion energy storage and then to the forward torsion energy storage.

Before the free tripping process starts, the state of the deflection torsion spring 25 is forward torsion energy storage (energy stored in the rebuckling energy storage process), and in the free tripping process, the state of the deflection torsion spring 25 is from forward torsion energy storage, energy is released, and then the energy is stored in reverse torsion.

The energy storage process and the free tripping process are one circulation process.

Before the energy storage is buckled again, the deflection torsion spring can be used for forward torsion energy storage; before free tripping, the deflection torsion spring can store energy for reverse torsion; namely, the deflection torsion spring is a cyclic process; the opposite torque set by the deflection torsion spring in the present embodiment can be realized by changing the rotation direction of the deflection torsion spring, and the same effect can be realized. This is the design goal of this embodiment, taking one way; the switching-on state of the electrical control system state switching unit is the normal use state of the electrical control system state switching unit; the state switching unit of the electric control system is in a closing state, and the state of the deflection torsion spring is in a forward torsion energy storage state.

According to the energy storage mechanism for the state switching operation of the electric control system, the independent tripping energy storage can be realized, namely, the tripping energy storage process and the energy storage process of the internal energy storage element of the state switching unit operation mechanism of the electric control system are respectively independent, before the state switching unit operation mechanism of the electric control system is operated, the tripping device needs to be rebuckled for energy storage, after the energy storage is rebuckled, the state switching unit operation mechanism of the electric control system can be normally operated, namely, before the state switching unit operation mechanism of the electric control system is operated, the tripping device needs to be rebuckled for energy storage, and before the energy storage is not rebuckled, the switching-on and switching-off operation cannot be carried out, so that the operation of the state switching unit operation mechanism of the electric control system is easier, and the energy storage mechanism is safe and reliable. The energy storage mechanism for the operation of the state switching unit of the electric control system has a free tripping function, and can still realize the tripping function and improve the safety performance of the state switching unit of the electric control system under the condition that the handle 16 or the handle rotating shaft is blocked at the moment of switching on the operation switch. And the structure is simple, the function is stable, and the energy release utilization rate of the energy storage element is high. In addition, the switching-on process of the energy storage mechanism and the switching-on process of the operating mechanism of the state switching unit of the electrical control system are operated at different time, so that the torsion moment in the energy storage process and the torsion moment in the switching-on process of the operating mechanism of the state switching unit of the electrical control system cannot be overlapped, and larger operating moment is avoided.
