Description

TECHNICAL FIELD

The present disclosure relates to an operating mechanism for a dual power transfer switch. The present disclosure also relates to a dual power transfer switch including the operating mechanism.

BACKGROUND

For the continuity of power supply in distribution system, more and more customers choose to use dual power transfer switch products. With the increase of the current level of the transfer switch (for example, the rated current reaches 800A-1600A), the structure of its operating mechanism module becomes more complicated. The present disclosure puts forward a new operating mechanism for a dual power transfer switch with three stations (including two stations), which can make the mechanism module more concise and easier to be modularized to meet more application requirements.

SUMMARY

In order to solve one or more defects in the existing art, according to one aspect of the present disclosure, an operating mechanism for a dual power transfer switch is proposed. The operating mechanism includes a first main spindle mechanism module including a rotatable main spindle, a rotation of the main spindle being able to drive a movable contact of the dual power transfer switch coupled with the first main spindle mechanism module to move between a first closing position and a second closing position, so that the dual power transfer switch is able to be switched between a first power supply and a second power supply, the first main spindle mechanism module being provided with a first closing spring, the first closing spring biases the first main spindle mechanism module to the first closing position and/or the second closing position; a first spring energy storage mechanism module, including a first opening spring, the first opening spring being connected to a manual energy storage device and/or an electric energy storage device to store energy for the first opening spring of the first spring energy storage mechanism module manually and/or electrically, and an output part of the first spring energy storage mechanism module being connected to the first main spindle mechanism module, and used to achieve an opening operation; an energy storage holding mechanism module, acting on the first spring energy storage mechanism module to keep locking the first spring energy storage mechanism module in a storage state; and an energy storage releasing mechanism module, acting on the energy storage holding mechanism module, wherein, upon the energy storage releasing mechanism module acting, the energy storage holding mechanism module no longer keeps locking the first spring energy storage mechanism module, so that the first spring energy storage mechanism module starts to release stored energy; upon the energy storage holding mechanism module releasing the first spring energy storage mechanism module, energy released by the first spring energy storage mechanism module causes the first main spindle mechanism module to rotate through a first transmission mechanism module, so that the first main spindle mechanism module moves away from the first closing position or the second closing position.
According the abovementioned aspect of the present disclosure, the operating mechanism further includes: a main spindle holding mechanism module capable of acting on the first main spindle mechanism module, so that the first main spindle mechanism module is able to be locked in a double-separation position; a first closing energy releasing mechanism module, acting on the main spindle holding mechanism module so that the main spindle holding mechanism module unlocks the first main spindle mechanism module in a direction to the first closing position, so that the first main spindle mechanism module is able to move from the double-separation position to the first closing position, so that the first power supply is switched on; a second closing energy releasing mechanism module, acting on the main spindle holding mechanism module so that the main spindle holding mechanism module unlocks the first main spindle mechanism module in a direction to the second closing position, so that the first main spindle mechanism module is able to move from the double-separation position to the second closing position, so that the second power supply is switched on.
According to the above contents of the present disclosure, the first closing spring has two energy releasing positions in different directions (corresponding to the first closing position and the second closing position respectively) and a dead point position (double-separation position), and the dead point position is held by a set of "main spindle holding mechanism module" and two sets of "closing energy releasing mechanism module" and the releasing directions are controlled. Therefore, in the present technical solution, a group of first closing springs can correspond to three working positions.
According to the above contents of the present disclosure, the first opening spring is able to store energy in advance, which has greater energy. When the energy is released, it not only drives the opening unit to open, but also stores energy for the first closing spring. This process is fast, so after opening, it can be quickly closed, which is beneficial to the rapid conversion of the dual power transfer switch.

According to the modular design of the present disclosure, the layout of the operating mechanism can be flexibly configured to adapt to more products, for example, three working positions can be changed into two working positions, and the positions of the main spindle holding mechanism module/the first closing energy releasing mechanism module/the second closing energy releasing mechanism module/the energy storage releasing mechanism module can be flexibly arranged.
According the abovementioned aspects of the present disclosure, the operating mechanism also includes at least one second core frame.
The main spindle of the first main spindle mechanism module and the energy storage shaft of the first spring energy storage mechanism module laterally penetrate the at least one second core frame.
A second main spindle mechanism module, a second spring energy storage mechanism module and a second transmission mechanism module are correspondingly installed in each of the at least one second core frame, the second main spindle mechanism module and the first main spindle mechanism module share a same main spindle, and the second spring energy storage mechanism module and the first spring energy storage mechanism module share a same energy storage shaft.

According the abovementioned aspects of the present disclosure, the first closing energy releasing mechanism module and the second closing energy releasing mechanism module are arranged at any side or above or below the main spindle holding mechanism module, and output parts of the first closing energy releasing mechanism module and the second closing energy releasing mechanism module are coupled with an input part of the main spindle holding mechanism module.
According the abovementioned aspects of the present disclosure, the main spindle holding mechanism module, the first closing energy releasing mechanism module and the second closing energy releasing mechanism module are arranged between the first core frame and the second core frame adjacent to the first core frame.
According the abovementioned aspects of the present disclosure, the rotation of the main spindle of the first main spindle mechanism module is able to drive a corresponding movable contact of a corresponding dual power transfer switch coupled with the second main spindle mechanism module to move between a first closing position and a second closing position, so that the corresponding dual power transfer switch is able to be switched between a first power supply and a second power supply, wherein the second main spindle mechanism module is provided with a second closing spring, and the second closing spring biases the second main spindle mechanism module to the first closing position and/or the second closing position.
The second spring energy storage mechanism module includes a second opening spring, the second opening spring is connected to the manual energy storage device and/or the electric energy storage device to store energy for the second opening spring of the second spring energy storage mechanism module manually and/or electrically, and an output part of the second spring energy storage mechanism module is coupled to the second main spindle mechanism module through a second transmission mechanism module for achieving an opening operation.

According to the above contents of the present disclosure, it is possible to expand the original single-core frame structure into a multi-core frame structure (namely, two sets of transmission mechanism modules/energy storage mechanism modules/main spindle mechanism modules), and only one set of corresponding holding mechanism module and corresponding releasing mechanism module (main spindle holding mechanism module/first closing energy releasing mechanism module/second closing energy releasing mechanism module/energy storage releasing mechanism module/energy storage holding mechanism module) is needed. The main spindle of the first main spindle mechanism module and the energy storage shaft of the first energy storage mechanism module can penetrate through a plurality of core frames, so as to ensure the synchronization of movement and control. Through such layout changes, it can be easily upgraded to a mechanism module with greater operating power, such as a three-station TSE with a rated current of 4000A.

As illustrated by Fig. 1 and Fig. 2, an operating mechanism 1 for a dual power transfer switch includes a first spring energy storage mechanism module 2, an energy storage holding mechanism module 3, an energy storage releasing mechanism module 4, a first transmission mechanism module 5 and a first main spindle mechanism module 6.
The first spring energy storage mechanism module 2 is able to store energy.
The energy storage holding mechanism module 3 is able to act on the first spring energy storage mechanism module 2, so that the first spring energy storage mechanism module 2 can hold the stored energy.
The energy storage releasing mechanism module 4 is able to act on the first spring energy storage mechanism module 2 through the energy storage holding mechanism module 3, so that the first spring energy storage mechanism module 2 can release the stored energy.
The energy released by the first spring energy storage mechanism module 2 acts on the first main spindle mechanism module 6 through the first transmission mechanism module 5, so that the first main spindle mechanism module 6 is able to store energy first and then release energy, and then the first main spindle mechanism module 6 moves between the first closing position and the second closing position.
The movement of the first main spindle mechanism module 6 between the first closing position and the second closing position enables the dual power transfer switch coupled with the first main spindle mechanism module 6 to switch between the first power supply and the second power supply.
As illustrated by Figs. 1 and 10, the operating mechanism 1 further includes a main spindle holding mechanism module 7, a first closing energy releasing mechanism module 8 and a second closing energy releasing mechanism module 9.
The main spindle holding mechanism module 7 is able to act on the first main spindle mechanism module 6, so that the first main spindle mechanism module 6 can be locked in the double-separation position (as illustrated by Fig. 10).
When the first closing energy releasing mechanism module 8 acts on the main spindle holding mechanism module 7, so that the main spindle holding mechanism module 7 unlocks the first main spindle mechanism module 6, the first main spindle mechanism module 6 is able to move from the double-separation position to the first closing position, and then the first power supply is switched on.
When the second closing energy releasing mechanism module 9 acts on the main spindle holding mechanism module 7, so that the main spindle holding mechanism module 7 unlocks the first main spindle mechanism module 6, the first main spindle mechanism module 6 is able to move from the double-separation position to the second closing position, and then the second power supply is switched on.
As illustrated by Figs. 1, 2 and 4, the operating mechanism further includes an electric energy storage mechanism module 10 and/or a manual energy storage mechanism module 11.
The electric energy storage mechanism module 10 and/or the manual energy storage mechanism module 11 act on the first spring energy storage mechanism module 2, so that the first spring energy storage mechanism module 2 stores energy.
As illustrated by Fig. 12, the operating mechanism includes a first core frame 12 as a part of the overall frame of the operating mechanism.
As illustrated by Fig. 13, the first main spindle mechanism module 6, the first spring energy storage mechanism module 2, the first transmission mechanism module 5 and the energy storage holding mechanism module 3 are accommodated in the first core frame 12.
As illustrated by Fig. 12, the electric energy storage mechanism module 10 and/or the manual energy storage mechanism module 11 are located at one side outside the first core frame 12, while the main spindle holding mechanism module 7, the first closing energy releasing mechanism module 8 and the second closing energy releasing mechanism module 9 are located at the other side outside the first core frame 12.
Of course, those skilled in the art can understand that the electric energy storage mechanism module 10 and/or the manual energy storage mechanism module 11 are located on the other side outside the first core frame 12, while the main spindle holding mechanism module 7, the first closing energy releasing mechanism module 8 and the second closing energy releasing mechanism module 9 are located on the one side outside the first core frame 12.
Compared with Fig. 12 and Fig. 13, as illustrated by Fig. 14 to Fig. 15, the main spindle holding mechanism module 7, the first closing energy releasing mechanism module 8 and the second closing energy releasing mechanism module 9 are removed, so that the operating mechanism is changed from three stations to two stations.
As illustrated by Figs. 16 and 17, the operating mechanism includes at least one second core frame 13 (only one is shown in Fig. 16 for clarity). The second core frame 13 is a part of the overall frame of the operating mechanism.
The main spindle 6-1 of the first main spindle mechanism module 6 and the energy storage shaft 2-1-1 of the first spring energy storage mechanism module 2 can penetrate through a plurality of second core frames.
Inside each second core frame 13, a second main spindle mechanism module (not shown), a second spring energy storage mechanism module (not shown) and a second transmission mechanism module (not shown) are accommodated.
The second main spindle mechanism module, the second spring energy storage mechanism module and the second transmission mechanism module respectively have the same structure and operating state as the first main spindle mechanism module 6, the first spring energy storage mechanism module 2 and the first transmission mechanism module 5.
The main spindle holding mechanism module 7, the first closing energy releasing mechanism module 8 and the second closing energy releasing mechanism module 9 are located between the first core frame 12 and the second core frame 13 adjacent to the first core frame 12.
The rotation of the main spindle 6-1 of the first main spindle mechanism module 6 is able to drive a corresponding movable contact of a corresponding dual power transfer switch coupled with the second main spindle mechanism module (not shown) to move between a first closing position and a second closing position, so that the corresponding dual power transfer switch is able to be switched between a first power supply and a second power supply, wherein the second main spindle mechanism module is provided with a second closing spring (not shown) which biases the second main spindle mechanism module to the first closing position and/or the second closing position.
The second spring energy storage mechanism module includes a second opening spring (not shown), which is connected to the manual energy storage device 10 and/or the electric energy storage device 11 to store energy for the second opening spring of the second spring energy storage mechanism module manually and/or electrically, and an output part of the second spring energy storage mechanism module is coupled to the second main spindle mechanism module through a second transmission mechanism module (not shown) for achieving an opening action.
The energy storage holding mechanism module 3 acts on the second spring energy storage mechanism module through the energy storage shaft 2-1-1 of the first spring energy storage mechanism module 2 to keep locking the second spring energy storage mechanism module in a storage state; and the energy storage releasing mechanism module 4 acts on the energy storage holding mechanism module 3, so that the energy storage holding mechanism module 3 no longer keeps locking the second spring energy storage mechanism module when the energy storage releasing mechanism module 4 acts, so that the second spring energy storage mechanism module starts to release the stored energy; when the energy storage holding mechanism module 3 releases the second spring energy storage mechanism module, the energy released by the second spring energy storage mechanism module causes the second main spindle mechanism module to rotate through the second transmission mechanism module, so that the second main spindle mechanism module moves away from the first closing position or the second closing position.
As illustrated by Fig. 3, the first spring energy storage mechanism module 2 includes an energy storage shaft assembly 2-1, an energy storage actuating assembly 2-2 (serving as the output part of the first spring energy storage mechanism module 2), and a first opening spring 2-3.
The electric energy storage mechanism module 10 and/or the manual energy storage mechanism module 11 are configured to drive the energy storage shaft assembly 2-1 to rotate.
The energy storage actuating assembly 2-2 is rotatably installed on the frame of the operating mechanism 1 (for example, through its pivot shaft 2-2-1), and one end of the energy storage actuating assembly 2-2 can be pivotally connected to the first opening spring 2-3.
The rotation of the energy storage shaft assembly 2-1 causes the first opening spring 2-3 to store energy through the energy storage actuating assembly 2-2.
The energy storage shaft assembly 2-1 includes an energy storage shaft 2-1-1 and an energy storage shaft cam 2-1-2 installed on the energy storage shaft 2-1-1 and taking the energy storage shaft 2-1-1 as the rotation axis.
As illustrated by Figs. 5 to 6, the energy storage actuating assembly 2-2 is provided with an actuating assembly roller B;
When the electric energy storage mechanism module 10 and/or the manual energy storage mechanism module 11 drive the energy storage shaft 2-1-1 to rotate (counterclockwise), the cam profile of the energy storage shaft cam 2-1-2 will push the actuating assembly roller B, and then drive the energy storage actuating assembly 2-2 to rotate (counterclockwise).
As illustrated by Figs. 5 to 6, the rotation of the energy storage actuating assembly 2-2 causes the first opening spring 2-3 to compress to store energy.
As illustrated by Figs. 5 and 6, the energy storage holding mechanism module 3 includes an energy storage holding lever 3-1 and a half shaft 3-2.
The energy storage holding lever 3-1 is pivotally installed on the frame of the operating mechanism 1, for example, through its pivot shaft 3-1-3.
The energy storage holding lever 3-1 includes a first end 3-1-1 and a second end 3-1-2.
The storage shaft cam 2-1-2 is provided with a main spindle cam roller A.
The first end 3-1-1 of the energy storage holding lever 3-1 is able to act on the main spindle cam roller A.
The second end 3-1-2 of the energy storage holding lever 3-1 is able to act on the half shaft 3-2.
As illustrated by Figs. 5 and 6, the half shaft 3-2 is rotatably connected to the frame of the operating mechanism 1.
A semicircular part is arranged on the half shaft 3-2, and the rotation of the half shaft 3-2 can block and give way to the rotation of the energy storage holding lever 3-1.
When the rotation of the half shaft 3-2 causes the semicircular part to give way to the second end 3-1-2 of the energy storage holding lever 3-1, the second end 3-1-2 of the energy storage holding lever 3-1 can rotatably pass through the semicircular part.
When the semicircular part blocks the second end 3-1-2 of the energy storage holding lever 3-1, the rotation of the second end 3-1-2 of the energy storage holding lever 3-1 is blocked by the semicircular part.
As illustrated by Figs. 5 and 6, the energy storage holding mechanism module 3 further includes a shift lever 3-3 (as an input part of the energy storage holding mechanism module).
The shift lever 3-3 is rotatably installed on the frame of the operating mechanism 1, for example, through its pivot shaft 3-3-1.
The shift lever 3-3 is able to act on the half shaft 3-2, so that the half shaft 3-2 can block or give way to the second end 3-1 -2 of the energy storage holding lever 3-1.
After the first opening spring 2-3 completes the compression energy storage (in Fig. 6, the first opening spring 2-3 is at the under-dead-center position), the main spindle cam roller A abuts against the first end 3-1-1 of the energy storage holding lever 3-1, the actuating assembly roller B abuts against the cam profile of the energy storage shaft cam 2-1-2, and the semicircular part blocks the second end 3-1-2 of the energy storage holding lever 3-1. The first end 3-1-1 of the energy storage holding lever 3-1 blocks the rotational moment acting on the energy storage shaft cam 2-1-2 due to the actuating assembly roller B, so that the energy storage shaft cam 2-1-2 will not rotate (the energy storage actuating assembly 2-2 will not rotate either), and the first opening spring 2-3 will not be extended to release energy.
The energy storage releasing mechanism module 4 includes an energy storage releasing electromagnetic driver having a releasing electromagnetic coil 4-1 and an electromagnetic coil movable iron core 4-2 (as an output part of the energy storage releasing mechanism module 4).
As illustrated by Fig. 6 to Fig. 8, in order to release the energy of the first opening spring 2-3, the electromagnetic coil 4-1 is energized, so that the electromagnetic coil movable iron core 4-2 acts on the shift lever 3-3, and the shift lever 3-3 is able to act on the half shaft 3-2, so that the semicircular part of the half shaft 3-2 can rotate without blocking the second end 3-1-2 of the energy storage holding lever 3-1. The rotation of the energy storage holding lever 3-1 causes its first end 3-1-1 not to block the main spindle cam roller A or the rotating moment acting on the energy storage shaft cam 2-1-2 due to the actuating assembly roller B, so that the energy storage holding lever 3-1 does not limit the expansion and energy release of the first opening spring 2-3, which is able to drive the energy storage actuating assembly 2-2 to rotate, and the actuating assembly roller B moves into a concave part of the gear profile of the storage shaft cam 2-1-2 (as shown in Fig. 8).
The energy storage releasing mechanism module 4 can be arranged at any side or above or below the energy storage holding mechanism module 3, and the output part of the energy storage releasing mechanism module 4 keeps coupling with the input part of the energy storage holding mechanism module 3, so as to drive and unlock the energy storage holding mechanism module 3 when the energy storage releasing mechanism module 4 acts.
The energy released by the expansion of the first opening spring 2-3 drives the energy storage actuating assembly 2-2 to move.
The movement of the energy storage actuating assembly 2-2 causes the first main spindle mechanism module 6 to rotate from the first closing position or the second closing position to the double-separation position through the transmission mechanism module.
As illustrated by Fig. 10, the first main spindle mechanism module 6 includes a main spindle 6-1, a main spindle crank arm 6-2 and a main spindle lock tongue 6-3 fixedly installed on the main spindle 6-1.
The main spindle holding mechanism module 7 includes a first locking piece 7-1 and a second locking piece 7-2.
Through the relative movement between the first locking piece 7-1 and the second locking piece 7-2, an openable and closable locking port 7-3 is formed between the first locking end of the first locking piece 7-1 and the second locking end of the second locking piece 7-2.
During the movement of the first main spindle mechanism module 6 between the first closing position and the second closing position, the locking port 7-3 can receive the main spindle lock tongue 6-3 and keep the main spindle lock tongue 6-3 between the first locking end of the first locking piece 7-1 and the second locking end of the second locking piece 7-2, so as to lock the first main spindle mechanism module 6 in a double-separation position between the first closing position and the second closing position.
As illustrated by Fig. 7, the main spindle crank arm 6-2 includes a first driven part 6-2-1 and a second driven part 6-2-2, both of which may be formed, for example, as a protrusions or the like at appropriate positions of the main spindle crank arm 6-2 for being driven by the transmission mechanism module 5 according to the present disclosure.
The first transmission mechanism module 5 includes a driving piece 5-1, which is able to move between an initial position and a driving position, and includes a first driving part 5-1-1 and a second driving part 5-1-2.
As illustrated by Fig. 7, when the first main spindle mechanism module 6 is in the first closing position, the first driving part 5-1-1 drives the first driven part 6-2-1 to move the first main spindle mechanism module 6 from the first closing position to the second closing position by the movement of the driving piece 5-1 from the initial position to the driving position.
When the first main spindle mechanism module 6 is in the second closing position, the second driving part 5-1-2 drives the second driven part 6-2-2 by the movement of the driving piece 5-1 from the initial position to the driving position, so that the first main spindle mechanism module 6 moves from the second closing position to the first closing position.
According to the present disclosure, the positions of the first driven part 6-2-1 and the second driven part 6-2-2 are changed correspondingly because the positions of the main shaft crank arm 6-2 at the first closing position and the second closing position are different, so the main shaft crank arm 6-2 can be realized by reasonably setting the positions of the first driven part 6-2-1 and the second driven part 6-2-2. When the first main spindle mechanism module 6 is in the first closing position, the first driven part 6-2-1 and the first driving part 5-1-1 are close to each other and the second driven part 6-2-2 and the second driving part 5-1-2 are far away from each other.
When the first main spindle mechanism module 6 is in the second closing position, the first driven part 6-2-1 and the first driving part 5-1-1 are far away from each other and the second driven part 6-2-2 and the second driving part 5-1-2 are close to each other.
With this arrangement, when the main spindle crank arm 6-2 is at any position, the driving piece 5-1 is able to drive the corresponding driven part only by one-way movement towards the driving position, so that the main spindle crank arm 6-2 moves towards another position.
Compared with the complicated existing art that two sets of driving devices are respectively arranged for the movement towards two positions, or a complex bidirectional driving mechanism module is arranged in one set of driving device, the invention can realize the two-position driving of the main spindle crank arm 6-2 by only arranging a single driving piece 5-1 capable of unidirectional movement.
It should be understood that the "unidirectional movement" here refers to that the driving direction of the driving piece 5-1 is unidirectional, but the driving piece 5-1 can still return to the initial position.
The driving piece 5-1 is set such that after the first driving part 5-1-1 drives the first driven part 6-2-1 and reaches the driving position of the driving part 5-1, the main spindle mechanism module 6 is locked in the double-separation position, and with the unlocking action of the second closing energy releasing mechanism module 9, the main spindle mechanism module 6 continues to move towards the second closing position, and the second driven part 6-2-2 drives the second driving part 5-1-2. After the second driving part 5-1-2 drives the second driven part 6-2-2 and reaches the driving position of the driver 5-1, the main spindle mechanism module 6 continues to move towards the first closing position with the unlocking action of the first closing energy releasing mechanism module 8, and the first driven part 6-2-1 exerts a force on the first driving part 5-1-1 to urge the driving piece 5-1 to return to the initial position.
The first driven part 6-2-1 and/or the second driven part 6-2-2 includes a roller. By setting the rollers, the interaction between the first driving part and the second driving part and the first driven part and second driven part can be improved, the friction can be reduced, and the movement between them can be smoother.
The first main spindle mechanism module 6 also includes a first closing spring 6-4.
When the first driving part 5-1-1 drives the first driven part 6-2-1, the first closing spring 6-4 stores energy. With the unlocking action of the second closing energy releasing mechanism module 9, after the first driving part 5-1-1 is separated from the first driven part 6-2-1, the first closing spring 6-4 releases the stored energy to move the first main spindle mechanism module 6 to the second closing position.
When the second driving part 5-1-2 drives the second driven part 6-2-2, the first closing spring 6-4 stores energy. With the unlocking action of the first closing energy releasing mechanism module 8, after the second driving part 5-1-2 is separated from the second driven part 6-2-2, the first closing spring 6-4 releases the stored energy to move the first main spindle mechanism module 6 to the first closing position.
As illustrated by Fig. 9, the first closing spring 6-4 is arranged as a compression spring and pivotally connected with one end of the main spindle crank arm 6-2, and when the driving piece 5-1 reaches the driving position, the compression spring is at the dead center position.
As illustrated by Fig. 7, the driving piece 5-1 has a pivot 5-2, and the driving piece 5-1 rotates around the pivot 5-2 between the initial position and the driving position.
The driving piece 5-1 is formed as a plate-like piece, a part of its outer contour is used as the first driving part 5-1-1, and another part of its outer contour is used as the second driving part 5-1-2.
The energy storage actuating assembly 2-2 is able to move between an initial position and an actuating position,
The energy storage actuating assembly 2-2 urges the driving piece 5-1 to move from the initial position to the driving position in the process of moving from the initial position to the actuating position.
The first transmission mechanism module 5 further includes a transmission piece 5-3, which is pivotally connected with the driving piece 5-1 through a pivot 5-4 and has a first end 5-3-1 and a second end 5-3-2 at both sides of the pivot 5-4.
The first end 5-3-1 is movably arranged in a chute 5-1-3 on the driving piece 5-1 , and the second end 5-3-2 is able to move along the first contour 2-2-2 of the energy storage actuating assembly 2-2 during the movement of the energy storage actuating assembly 2-2 from the initial position to the actuating position, so that the energy storage actuating assembly 2-2 urges the driving member 5-3 to move from the initial position to the driving position through the transmission piece 5-3.
The driving piece 5-1 includes a return spring (not shown) that can return the driving piece 5-1 from the driving position to the initial position, and the return spring is connected to the first end 5-3-1 of the transmission piece 5-3.
During the movement of the energy storage actuating assembly 2-2 from the initial position to the actuating position, the first contour 2-2-2 applies a first torque to the second end 5-3-2 around the pivot 5-4 of the transmission piece 5-3, so that the first end 5-3-1 of the transmission piece 5-3 remains to abut against the end of the chute 5-1-3.
As illustrated by Fig. 7, the energy storage actuating assembly 2-2 further includes a second profile 2-2-3 that is continuous with the first profile 2-2-2.
After the energy storage actuating assembly 2-2 reaches the actuating position, the second end 5-3-2 of the driving piece 5-1 disengages from the first profile 2-2-2 of the energy storage actuating assembly 2-2 and moves to the second profile 2-2-3.
When the second end 5-3-2 of the transmission piece 5-3 moves to the part of the second profile 2-2-3 that is connected with the first profile 2-2-2, the connected part applies a second torque to the second end 5-3-2 around the pivot 5-4 of the transmission piece 5-3, so that the second end 5-3-2 of the transmission piece 5-3 moves along the second profile 2-2-3, and the second torque is opposite to the first torque.
During the return of the energy storage actuating assembly 2-2 from the actuating position to the initial position, the second profile 2-2-3 of the energy storage actuating assembly 2-2 moves away from the second end 5-3-2 of the transmission piece 5-3.
After the second profile 2-2-3 of the energy storage actuating assembly 2-2 moves away from the second end 5-3-2 of the transmission piece 5-3, the return spring continues to contract and rotate the transmission piece 5-3 around its pivot 5-4, so that the second end 5-3-2 of the transmission piece 5-3 returns to the first profile 2-2-2 of the energy storage actuating assembly 2-2.
The energy storage shaft assembly 2-1 can release energy storage to the energy storage actuating assembly 2-2 to move the energy storage actuating assembly 2-2 from the initial position to the actuating position.
As illustrated by Fig. 5, the first opening spring 2-3 includes a fixed pivot end 2-3-1 and a movable pivot end 2-3-2 pivotally connected to the energy storage actuating assembly 2-2.
As illustrated by Fig. 6, the electric energy storage mechanism module 10 and/or the manual energy storage mechanism module 11 drive the energy storage shaft 2-1-1 to rotate counterclockwise (store energy), the energy storage shaft cam 2-1-2 rotates, and its cam surface pushes the actuating assembly roller B, and the actuating assembly roller B drives the energy storage actuating assembly 2-2 to rotates counterclockwise (from the actuating position to the initial position), and the energy storage actuating assembly 2-2 compress the first opening spring 2-3 to store energy.
During the movement of the first main spindle mechanism module 6 from the first closing position to the second closing position, the main spindle lock tongue 6-3 applies a first opening action to the first locking piece 7-1 to completely open the locking port 7-3.
During the movement of the first main spindle mechanism module 6 from the second closing position to the first closing position, the main spindle lock tongue 6-3 applies a second opening action to the second locking piece 7-2 to completely open the locking port 7-3.
During the first opening action, after the first locking piece 7-1 moves to its limit position, the first locking piece 7-1 causes the main spindle lock tongue 6-3 to make the first return action towards the locking position.
During the second opening action, after the second locking piece 7-2 moves to its limit position, the second locking piece 7-2 causes the main spindle lock tongue 6-3 to make a second return action towards the locking position.
The first locking piece 7-1 has a first biasing mechanism module 7-1-1, and the first biasing mechanism module 7-1-1 applies a force to the first locking piece 7-1 that tends to make the first locking piece 7-1 close the locking port 7-3.
The second locking piece 7-2 has a second biasing mechanism module 7-2-1, and the second biasing mechanism module 7-2-1 applies a force to the second locking piece 7-2 that tends to make the second locking piece 7-2 close the locking port 7-3.
The first locking piece 7-1 is arranged to pivot around a first pivot 7-1-2, and the torque applied to the first locking end by the main spindle lock tongue 6-3 is in the same direction as that applied to the first locking piece 7-1 by the first biasing mechanism module 7-1-1 of the first locking piece 7-1.
The second locking piece 7-2 is arranged to pivot around a second pivot 7-2-2, and the torque applied to the second locking end by the main spindle lock tongue 6-3 is in the same direction as that applied to the second locking piece 7-2 by the second biasing mechanism module 7-2-1 of the second locking piece 7-2.
The first locking end has an arc surface 7-1-3, the center of which is not concentric with the rotation center of the first pivot 7-1-2 and/or the second locking end has an arc surface 7-2-3, and the center of which is not concentric with the rotation center of the second pivot 7-2-2.
The first locking piece 7-1 includes a first free end; the second locking member 7-2 includes a second free end. The first free end and the second free end serve as input parts of the main spindle holding mechanism module 7.
As illustrated by Fig. 11, the first closing energy releasing mechanism module 8 is configured as a first electromagnetic driver, which has a first electromagnetic coil 8-1 and a first movable iron core 8-2 (as the output part of the first closing energy releasing mechanism module 8) that is able to actuate the second free end of the second locking piece 7-2. The movement of the first movable iron core 8-2 causes the second locking piece 7-2 to move away from the main shaft lock tongue 6-3 to give way. Driven by the first locking piece 7-1, the main spindle lock tongue 6-3 causes the first closing spring 6-4 pass through the dead point, and the first closing spring 6-4 releases energy, so that the main spindle mechanism module 6 rotates from the double-separation position to the first closing position, and the second locking piece 7-2 is reset.
The first electromagnetic driver can be arranged at the lower side (as illustrated by Fig. 11) or a lateral side (left side or right side, not shown) of the second locking piece 7-2, so that the movement of the first movable iron core 8-2 enables the second locking piece 7-2 to move away from the main spindle lock tongue 6-3 to give way.
As illustrated by Fig. 1, the second closing energy releasing mechanism module 9 is configured as a second electromagnetic driver, which has a second electromagnetic coil 9-1 and a second movable iron core 9-2 (as the output part of the second closing energy releasing mechanism module 9) that is able to actuate the first free end of the first locking piece 7-1, and the movement of the second movable iron core 9-2 causes the first locking piece 7-1 to move away from the main spindle lock tongue 6-3 to give way. Driven by the second locking piece 7-2, the main spindle lock tongue 6-3 causes the first closing spring 6-4 to pass through the dead point, and the first closing spring 6-4 releases energy, so that the main spindle mechanism module 6 rotates from the double-separation position to the second closing position, and the first locking piece 7-1 is reset.
The second electromagnetic driver can be arranged at the upper side (as illustrated by Fig. 1) or a lateral side (left side or right, not shown) of the first locking piece 7-1, so that the movement of the second movable iron core 9-2 enables the first locking piece 7-1 move away from the main spindle lock tongue 6-3 to give way.
That is to say, the first closing energy releasing mechanism module 8 and the second closing energy releasing mechanism module 9 can be arranged at any side or above or below the main spindle holding mechanism module 7, while the output parts of the first closing energy releasing mechanism module 8 and the second closing energy releasing mechanism module 9 keep matching with the input part of the main spindle holding mechanism module 7.
According to the above embodiments of the present disclosure, the principle and operation flow of the operating mechanism with three stations are as follows:

1. Energy storage of the first opening spring: electric energy storage mechanism module and/or manual energy storage mechanism module → first opening spring energy storage (+energy storage holding mechanism module locks the first opening spring);
2. Opening: the energy storage releasing mechanism module acts → the energy storage holding mechanism module unlocks the first opening spring → the first opening spring releases energy → the first transmission mechanism module → the main spindle of the first main spindle mechanism module (+the first closing spring stores energy + the main spindle holding mechanism module locks the main spindle of the first main spindle mechanism module) → the breaking unit opens (double-separation position);
3. Closing of the first power supply S1: the first closing energy releasing mechanism module acts → the main spindle holding mechanism module trips to S1 → the first closing spring releases energy → the main spindle of the first main spindle mechanism module rotates to S1 → the breaking unit closes (the first closing position); or

Closing of the second power supply S2: the second closing energy releasing mechanism module acts → the main spindle holding mechanism module trips to S2 → the first closing spring releases energy → the main spindle of the first main spindle mechanism module rotates to S2 → the breaking unit closes (the second closing position).
According to the above-mentioned embodiments of the present disclosure, the main spindle holding mechanism module, the first closing energy releasing mechanism module and the second closing energy releasing mechanism module can be removed, and the three-station operating mechanism can be changed into two-station operating mechanism. The principle and operation flow are as provided follows (taking the first power supply S1 closing to the second power supply S2 closing as an example):

1. Energy storage of the first opening spring: electric energy storage mechanism module and/or manual energy storage mechanism module → first opening spring energy storage (+energy storage holding mechanism module locks the first opening spring);
2. Conversion: the energy storage releasing mechanism module acts → the energy storage holding mechanism module unlocks the first opening spring → the first opening spring releases energy → the first transmission mechanism module → the main spindle of the first main spindle mechanism module (+the first closing spring directly releases energy after storing energy and drives the main spindle of the first main spindle mechanism module to continue rotating) → the breaking unit switches from S1 to S2 (from the first closing position to the second closing position).

According to the above embodiment of the present disclosure, the first closing spring has two energy releasing positions in different directions (corresponding to the first closing position and the second closing position respectively) and a dead point position (double-separation position), and the dead point position is maintained by a set of "spindle holding mechanism module" and two sets of "closing energy releasing mechanism module" and the releasing directions are controlled. Therefore, in the technical solution, a group of first closing springs can correspond to three working positions.
According to the above contents of the present disclosure, the first opening spring is able to store energy in advance, which has greater energy. When the energy is released, it not only drives the opening unit to open, but also stores energy for the first closing spring. This process is fast, so after opening, it can be quickly closed, which is beneficial to the rapid conversion of the dual power transfer switch.
According to another embodiment of the present disclosure, a dual power transfer switch is provided, the dual power transfer switch includes the operating mechanism as described above.
According to the modular design of the present disclosure, the layout of the operating mechanism can be flexibly configured to adapt to more products, for example, three working positions can be changed into two working positions, and the positions of the main spindle holding mechanism module/the first closing energy releasing mechanism module/the second closing energy releasing mechanism module/the energy storage releasing mechanism module can be flexibly arranged.
According to the above contents of the present disclosure, it is possible to expand the original single-core frame structure into a multi-core frame structure (namely, two sets of transmission mechanism modules/energy storage mechanism modules/main spindle mechanism modules), and only one set of corresponding holding mechanism module and corresponding releasing mechanism module (main spindle holding mechanism module/first closing energy releasing mechanism module/second closing energy releasing mechanism module/energy storage releasing mechanism module/energy storage holding mechanism module) is needed. The main spindle of the first main spindle mechanism module and the energy storage shaft of the first energy storage mechanism module can penetrate through a plurality of core frames, so as to ensure the synchronization of movement and control. Through such layout changes, it can be easily upgraded to a mechanism module with greater operating power, such as a three-station TSE with a rated current of 4000A.
The foregoing disclosure provides illustration and description, but is not intended to be exhaustive or to limit the embodiments to the precise forms disclosed. Modifications and variations are possible in light of the above disclosure, or may be acquired from practice of the embodiments.
Even if specific combinations of features are recited in the claims and/or disclosed in the specification, these combinations are not intended to limit the present disclosure of various embodiments. In fact, many of these features can be combined in ways not specifically recited in the claims and/or not specifically disclosed in the specification.
