Illustratively, as shown in fig. 1, 3 and 11, the trip assembly, the linkage assembly 100, the latch assembly 200, and the rotation assembly 300 are disposed on the base 110. The tripping assembly comprises a tripper 401 and a signal terminal, the signal terminal is in signal connection with the tripper 401, the signal terminal can be connected with the outside in a wireless transmission mode (a power supply device is arranged in a matched mode), and the signal terminal can also be a signal interface and is connected with the outside through a signal wire. The trip unit 401 may be of a hydro-magnetic type or an electromagnetic type, etc., and as shown in fig. 12, it may control the extension or retraction of the telescopic end thereof under the action of a signal received by the signal terminal. Taking fig. 3 as an example, the release 401 can move in an extending manner to push one end of the linkage assembly 100 abutting against the release to push the release outward (i.e., to the left in fig. 3).

As shown in fig. 1 and 3, the linkage assembly 100 is rotatably disposed on the base 110, and a first abutting portion 104 is disposed on the base, and the first abutting portion 104 may be a protrusion, a baffle, or the like. As shown in fig. 14, the latch assembly 200 includes a latch member and a first elastic member 204, wherein the latch member is also rotatably connected to the base 110, and as shown in fig. 1, the rotation axis of the latch member is parallel to the rotation axis of the linkage assembly 100. The first elastic element 204 is disposed on the rotation shaft of the locking element rotatably connected to the base 110, and always provides an acting force to the locking element, and the direction of the acting force is clockwise in fig. 3, i.e. the left end of the locking element (i.e. the end engaged with the first abutting portion 104) in fig. 3 tends to rotate clockwise around the rotation shaft of the locking element. The latch is further provided with a second abutting portion 202, a first clamping portion 203 and a reset protrusion 201, wherein the second abutting portion 202 can be arranged at the left end of the latch as shown in fig. 3, and is actually matched and abutted with the first abutting portion 104 through an abutting surface or an abutting side arranged thereon.

As shown in fig. 1, the rotating assembly 300 includes a rotating member and a second elastic member 303, wherein the rotating member is disposed on the base 110 in a manner of rotating relative to the base 110, and a rotating plane of the rotating member may intersect or be perpendicular to a rotating plane of the linkage assembly 100 and the locking member, i.e., the rotating axis intersects or is perpendicular (vertical in fig. 3). The rotating member may be provided with a second clamping portion 302, and two side edges of the second clamping portion 302 may be respectively matched with the reset protrusion 201 and the first clamping portion 203 on the locking member in different states, so as to respectively complete the actual matching and abutting of the first abutting portion 104 and the second abutting portion 202 and the locking of the state after the energy storage (i.e., compression) of the second elastic member 303.

In the actual working process, the second elastic member 303 needs to be compressed first, that is, the whole device is stored with energy, so that when needed, the reverse rotation of the rotating member is completed by releasing the energy stored in the second elastic member 303 (i.e., tripping). Firstly, external force is required to be applied to the rotating member, and the external force can be applied by a machine or a hand. The rotating member is rotated in the forward direction (i.e. clockwise in fig. 2), so that the second elastic member 303 connected to the rotating member is compressed until the second engaging portion 302 on the rotating member is rotated to abut against the reset protrusion 201 (i.e. the state shown in fig. 4) on the locking member in the inclined state (the inclined angle should be greater than or equal to the preset angle, which is the embodiment in fig. 3), at this time, the rotating member is rotated continuously, and the reset protrusion 201 in the inclined state is driven to rotate by the second engaging portion 302 (i.e. the entire locking member is rotated in the counterclockwise direction in fig. 4 by a certain angle, which is equal to the inclined angle of the reset protrusion 201, which may also be smaller than the inclined angle of the reset protrusion 201 in other embodiments) until the two abut against each other, that is, the state when the maximum contact surface is reached. At this moment, the linkage assembly 100 is pushed to move in the right direction in fig. 4 (i.e., rotate in the counterclockwise direction in fig. 4) under the driving of the external force, so as to drive the first abutting portion 104 to rotate to the position where it can abut against the second abutting portion 202, at this moment, the external force exerted on the rotating member is loosened, the second clamping portion 302 is matched with the first clamping portion 203 of the locking member under the action of the second elastic member 303 (in the direction opposite to the compression direction) to complete the locking, i.e., the whole energy storage process is completed.

After the energy storage process is completed, when the signal terminal receives a signal indication, the control release 401 extends (shown in fig. 4), and drives the first abutting portion 104 to disengage from the second abutting portion 202, at this time, the locking member rotates clockwise in fig. 4 under the action of the first elastic member 204, at this time, the first clamping portion 203 disengages from the second clamping portion 302, that is, both release the locking. The rotating member rotates counterclockwise in fig. 6 (i.e., the rotating member rotates in the opposite direction, as shown in fig. 5) under the action of the second elastic member 303, and drives the mechanism on the circuit breaker to operate, thereby completing the remote circuit breaking. The breaking speed and breaking capacity of the breaker in the fault are improved, and meanwhile, the flexibility of the breaker can be improved in a remote control mode.

First, to avoid the misoperation, before the energy storage, the first abutting portion 104 and the left end of the locking piece form an interference limit to prevent the first abutting portion 104 from rotating to a position where the first abutting portion 202 can abut against each other. The predetermined angle is an angle required for the latch to rotate counterclockwise in fig. 4 to a position where the first abutting portion 104 can be driven by the linkage assembly 100 to rotate to abut against the second abutting portion 202 (the first abutting portion 104 no longer interferes with the left end of the latch for limiting, i.e., the first abutting portion 104 and the second abutting portion 202 are in a corresponding state) in the original state when the first elastic member 204 acts on the latch.

Second, the telescopic end of the trip unit 401 in the present application is determined by the structure of the trip unit 401 when the telescopic end correspondingly realizes the extending or retracting action under the control signal. For example, when the release 401 is a shunt release, the corresponding release 401 should drive the linkage assembly 100 to operate in an active extending manner, and at this time, in cooperation with the subsequent reset operation (reset button 105), an external force is required to push the reset button 105 to drive the linkage assembly 100 to reset, and at the same time, to drive the telescopic end of the shunt release to reset. When the trip unit 401 has the active retraction function, the corresponding reset button 105 is not needed to be set in the subsequent reset phase.

Optionally, the linkage assembly 100 includes a trip bar 101 and a latch bar 102; the trip bar 101 and the lock bar 102 are coaxial and are inserted into each other along the axial direction, one end of the trip bar 101 abuts against the telescopic end of the release 401, and the first abutting portion 104 is located at one end of the lock bar 102.

Illustratively, as shown in fig. 9 and 10, the linkage assembly 100 may include a trip bar 101 and a latch bar 102, wherein the trip bar 101 is coaxial with the latch bar 102, i.e., both are rotatably connected to the base 110 via the same rotational axis. In order to enable the two to form a transmission relationship, the two are connected in a manner of being inserted into each other along the axial direction of the rotating shaft. Meanwhile, the trip bar 101 can be in a T-shaped structure, so that one end of the trip bar 101, which is far away from the rotating shaft, is abutted against the telescopic end of the release 401, and meanwhile, the first abutting part 104 is arranged on the lock catch bar 102.

Optionally, the linkage assembly 100 further includes a third elastic member 103; the trip bar 101 comprises a trip bar 101 body and a first half shaft arranged on the trip bar 101 body; the latch lever 102 includes a latch lever 102 body and a second half shaft disposed on the latch lever 102 body; the first half shaft and the second half shaft are mutually spliced so that the trip bar 101 and the lock catch lever 102 are coaxial, a gap is formed between the first half shaft and the second half shaft along the circumferential direction, and the third elastic piece 103 is sleeved on the peripheries of the first half shaft and the second half shaft and is respectively connected with the trip bar 101 and the lock catch lever 102 and used for enabling one end of the trip bar 101 to be abutted against the telescopic end of the release 401 and enabling the first abutting part 104 at one end of the lock catch lever 102 to be abutted against the second abutting part 202.

Illustratively, as shown in fig. 9 and 10, the trip bar 101 includes a body of the trip bar 101 and a first half shaft disposed on the body of the trip bar 101. similarly, the lock bar 102 includes a body of the trip bar 102 and a second half shaft disposed on the body of the trip bar 102. the insertion is accomplished by displacing the first half shaft and the second half shaft from each other for insertion, so that the trip bar 101 and the lock bar 102 are coaxial and form a transmission relationship. The linkage assembly 100 may further include a third elastic member 103, wherein the third elastic member 103 is disposed around the first and second half shafts, and two elastic ends of the third elastic member 103 are respectively abutted against the trip lever 101 and the lock lever 102 (i.e. as shown in fig. 9, a protrusion is provided on the trip lever 101 for abutting against the elastic end of the third elastic member 103, as shown in fig. 10, a protrusion is provided on the lock lever 102 for abutting against the other elastic end of the third elastic member 103), and at the same time, another elastic end of the third elastic member 103 can also be abutted against the base 110, thereby providing the trip lever 101 and the latch lever 102 with forces tending to rotate counterclockwise in figure 4, the acting force can enable the tripping rod 101 to be always kept tightly against the telescopic end of the tripper 401, so that the tripping rod and the telescopic end of the tripper 401 can conveniently and timely transmit the acting force, and the phenomenon that the virtual position causes the slow action and long action time of the whole remote short-circuit device is avoided. At the same time, the first abutting portion 104 may always be closer to the second abutting portion 202, and the stability when the first abutting portion 104 and the second abutting portion 202 are in the abutting state may be improved. Meanwhile, a gap may be formed between the first half shaft and the second half shaft, that is, a gap with a certain distance is formed along the circumferential direction of rotation of the linkage assembly 100, and the lower ends of the first half shaft and the second half shaft in fig. 5 may be tightly attached through the cooperation of the gap and the third elastic member 103, and meanwhile, in this embodiment, another operation step of the energy storage stage may be provided, as follows:

before the external force is applied to the rotating member, the trip rod 101 can be moved in the right direction in fig. 4 by applying the external force to the trip rod, because the first half shaft and the second half shaft have a distance at the upper end, and the first abutting portion 104 abuts against the left end (shown in fig. 4) of the locking member for limiting, so that the locking member cannot follow the trip rod 101 under the action of the third elastic member 103, therefore, with the continuous rotation of the trip rod 101, the gap between the upper ends of the first half shaft and the second half shaft is reduced, and the gap between the lower ends of the first half shaft and the second half shaft is increased continuously until the gap between the upper ends is reduced to zero (in other embodiments, it may be non-zero), at this time, the third elastic member 103 provides the first abutting portion 104 with a tendency of rotating counterclockwise in fig. 4. Thereafter, an external force is applied to the rotating member to rotate the rotating member clockwise in fig. 6 until the second clamping portion 302 drives the locking member to rotate to the position where the first abutting portion 104 corresponds to the second abutting portion 202, at this time, the abutting limit of the left end portion of the first abutting portion 104 and the locking member is cancelled, and the first abutting portion enters the position where the second abutting portion 202 can abut. Thereby performing the position limitation of the locking member so that the first clamping portion 203 and the second clamping portion 302 form a locking state.

It should be noted that, the size of the gap should be reasonably set according to actual requirements, for example, in this embodiment, the gap may be set according to a stroke from the position where the first abutting portion 104 abuts against the lock catch left end to the position where the first abutting portion 202 can abut against the lock catch left end, so that it can be avoided that the first abutting portion 104 rotates excessively, which results in that the first abutting portion 104 and the second abutting portion 202 cannot abut against each other well.

Optionally, the third elastic member 103 is a reset double torsion spring; the reset double torsion spring is sleeved on the peripheries of the first half shaft and the second half shaft, one end of the reset double torsion spring is abutted to the trip rod 101, and the other end of the reset double torsion spring is abutted to the lock catch rod 102.

For example, as shown in fig. 13, the third elastic member 103 may be a restoring double torsion spring, wherein the restoring double torsion spring is sleeved on the peripheries of the first half shaft and the second half shaft, and meanwhile, one end of the restoring double torsion spring abuts against the release 401, the other end abuts against the lock lever 102, and the third end abuts against the base 110. The double torsion springs are arranged, so that the manufacturing cost can be reduced, and the stability of the remote circuit breaking device is improved.
