Description

Technical Field

[0001] The present disclosure relates to an operating mechanism for a dual power transfer switch and also relates to a dual power transfer switch comprising the operating mechanism. Background Art

[0002] For the power supply continuity of the power 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 proposes a new operating mechanism for a dual power transfer switch with three positions (including two positions), which can make the mechanism module design more concise and easy to modularize to meet more application requirements. Summary of the invention

[0003] In order to solve one or more defects in the prior art, according to one aspect of the present disclosure, an operating mechanism for a dual power conversion switch is proposed, wherein the operating mechanism comprises: a first spindle mechanism module, comprising a rotatable spindle, the rotation of which can drive the moving contact of the dual power conversion switch matched with the first spindle mechanism module to move between a first closing position and a second closing position, so that the dual power conversion switch switches between the first power supply and the second power supply, wherein a first closing spring is arranged on the first spindle mechanism module, and the first closing spring biases the first spindle mechanism module to the first closing position and / or the second closing position; a first spring energy storage mechanism module, comprising a first opening spring, and the first spring energy storage mechanism module is connected to a manual energy storage device and / or an electric energy storage device to manually and / or electrically open the first spring energy storage mechanism module. Spring energy storage, the output part of the first spring energy storage mechanism module is connected to the first main shaft mechanism module through the first transmission mechanism module, so as to realize the opening action; the energy storage holding mechanism module acts on the first spring energy storage mechanism module to keep the first spring energy storage mechanism module locked in the storage state; and the energy storage release mechanism module acts on the energy storage holding mechanism module, when the energy storage release mechanism module acts, the energy storage holding mechanism module can no longer keep the first spring energy storage mechanism module locked, so that the first spring energy storage mechanism module starts to release the stored energy; wherein when the energy storage holding mechanism module releases the first spring energy storage mechanism module, the energy released by the first spring energy storage mechanism module causes the first main shaft mechanism module to rotate through the first transmission mechanism module, so that the first main shaft mechanism module moves away from the first closing position or away from the second closing position.

[0004] According to the above aspects of the present disclosure, the operating mechanism also includes: a spindle holding mechanism module, which can act on the first spindle mechanism module so that the first spindle mechanism module can be locked in the double-open position; a first closing energy release mechanism module, which acts on the spindle holding mechanism module so that the spindle holding mechanism module releases the lock on the first spindle mechanism module in the direction of the first closing position, so that the first spindle mechanism module can move from the double-open position to the first closing position, so that the first power supply is closed; and a second closing energy release mechanism module, which acts on the spindle holding mechanism module so that the spindle holding mechanism module releases the lock on the first spindle mechanism module in the direction of the second closing position, so that the first spindle mechanism module can move from the double-open position to the second closing position, so that the second power supply is closed.

[0005] According to the above content of the present disclosure, the first closing spring has two energy release positions in different directions (corresponding to the first closing position and the second closing position, respectively), and a dead point position (double-open position), and its dead point position is held and controlled by a set of "spindle holding mechanism modules" + two sets of "closing energy release mechanism modules" to control the release direction. Therefore, in this solution, a set of first closing springs can correspond to three working positions.

[0006] According to the above contents of the present disclosure, the first opening spring can store energy in advance, and it has greater energy. When released, it not only drives the disconnecting unit to open the circuit, but also stores energy for the first closing spring. This process is fast, so after opening the circuit, it can be quickly closed, which is conducive to the rapid conversion of the dual power conversion switch.

[0007] According to the above aspects of the present disclosure, the operating mechanism includes a first movement frame.

[0008] The first spindle mechanism module, the first spring energy storage mechanism module, the first transmission mechanism module and the energy storage holding mechanism module are installed in a first movement frame.

[0009] The main shaft of the main shaft mechanism module passes through the first movement frame laterally and is rotatably mounted on the first movement frame.

[0010] The first spring energy storage mechanism module includes an energy storage shaft, which is connected to the first opening spring, so that the rotation of the energy storage shaft can store energy for the first opening spring. The electric energy storage mechanism module and / or the manual energy storage mechanism module are sleeved on the energy storage shaft, thereby driving the energy storage shaft to rotate.

[0011] The energy storage shaft is arranged parallel to the main shaft of the first main shaft mechanism module, passes through the first movement frame laterally and is rotatably mounted on the first movement frame.

[0012] The electric energy storage mechanism module and / or the manual energy storage mechanism module are located on the first side outside the first movement frame; the spindle holding mechanism module, the first closing energy release mechanism module and the second closing energy release mechanism module are located on the second side outside the first movement frame opposite to the first side, or the electric energy storage mechanism module and / or the manual energy storage mechanism module are located on the second side outside the first movement frame; the spindle holding mechanism module, the first closing energy release mechanism module and the second closing energy release mechanism module are located on the first side outside the first movement frame.

[0013] 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 shaft holding mechanism module / the first closing energy release mechanism module / the second closing energy release mechanism module / the energy storage release mechanism module can be flexibly arranged.

[0014] According to the above aspects of the present disclosure, the operating mechanism further includes at least one second movement frame.

[0015] The main shaft of the first main shaft mechanism module and the energy storage shaft of the first spring energy storage mechanism module laterally penetrate the at least one second movement frame.

[0016] A corresponding second spindle mechanism module, a second spring energy storage mechanism module, and a second transmission mechanism module are installed in each second movement frame, wherein the second spindle mechanism module and the first spindle mechanism module share the same spindle, and the second spring energy storage mechanism module and the first spring energy storage mechanism module share the same energy storage shaft.

[0017] According to the above-mentioned various aspects of the present disclosure, the energy storage release mechanism module can be arranged on any side or above and below the energy storage retaining mechanism module, and at the same time, the output part of the energy storage release mechanism module is kept in coordination with the input part of the energy storage retaining mechanism module to drive and unlock the energy storage retaining mechanism module when the energy storage release mechanism module is actuated.

[0018] According to the above-mentioned various aspects of the present disclosure, the first closing energy release mechanism module and the second closing energy release mechanism module can be arranged on any side or above and below the spindle holding mechanism module, and at the same time, the output parts of the first closing energy release mechanism module and the second closing energy release mechanism module are kept in coordination with the input part of the spindle holding mechanism module.

[0019] According to the above-mentioned various aspects of the present disclosure, the spindle holding mechanism module, the first closing energy release mechanism module and the second closing energy release mechanism module are arranged between the first movement frame and a second movement frame adjacent to the first movement frame.

[0020] According to the above-mentioned various aspects of the present disclosure, the rotation of the main shaft of the first main shaft mechanism module can drive the corresponding moving contact of the corresponding dual power conversion switch cooperating with the second main shaft mechanism module to move between the first closing position and the second closing position, thereby making the corresponding dual power conversion switch switch between the first power supply and the second power supply, wherein the second main shaft mechanism module is provided with a second closing spring, and the second closing spring biases the second main shaft mechanism module to the first closing position and / or the second closing position.

[0021] The second spring energy storage mechanism module includes a second opening spring, and the second spring energy storage mechanism module is connected to a manual energy storage device and / or an electric energy storage device to store energy for the second opening spring of the second spring energy storage mechanism module manually and / or electrically. The output part of the second spring energy storage mechanism module is connected to the second main shaft mechanism module through a second transmission mechanism module for realizing the opening action.

[0022] The energy storage holding mechanism module acts on the second spring energy storage mechanism module through the energy storage shaft to keep the second spring energy storage mechanism module locked in a storage state; and the energy storage release mechanism module acts on the energy storage holding mechanism module, so that when the energy storage release mechanism module is actuated, the energy storage holding mechanism module no longer keeps the second spring energy storage mechanism module locked, so that the second spring energy storage mechanism module begins to release the stored energy; wherein when the energy storage holding mechanism module releases the second spring energy storage mechanism module, the energy released by the second spring energy storage mechanism module causes the second spindle mechanism module to rotate through the second transmission mechanism module, so that the second spindle mechanism module moves away from the first closing position or away from the second closing position.

[0023] According to the above contents of the present disclosure, the structure of the original single movement frame can be expanded into a multi-movement frame structure (i.e., two sets of transmission mechanism modules / energy storage mechanism modules / spindle mechanism modules), and only one set of corresponding holding mechanism modules and corresponding release mechanism modules (spindle holding mechanism module / first closing energy release mechanism module / second closing energy release mechanism module / energy storage release mechanism module / energy storage holding mechanism module) is required. The spindle of the first spindle mechanism module and the energy storage shaft of the first energy storage mechanism module can pass through multiple movement frames to ensure motion synchronization and control synchronization. Through such layout changes, it can be easily upgraded to a mechanism module with a larger operating power, such as a three-station TSE with a rated current of 4000A.

[0024] According to another aspect of the present disclosure, a dual power transfer switch is provided, wherein the dual power transfer switch includes the operating mechanism as described above.

[0025] Thus far, in order that the detailed description of the present disclosure herein can be better understood, and in order that the contribution of the present disclosure to the prior art can be better appreciated, the present disclosure has been fairly broadly outlined. Of course, embodiments of the present disclosure will be described below and will form the subject matter of the appended claims.

[0026] Likewise, those skilled in the art will recognize that the conception upon which the present disclosure is based can be easily used as the basis for designing other structures, methods and systems for implementing the several purposes of the present disclosure. Therefore, it is important that the appended claims should be considered to include such equivalent structures as long as they do not exceed the essence and scope of the present disclosure.

[0048] like Figure 1 and Figure 2 As shown, an operating mechanism 1 for a dual power conversion switch includes a first spring energy storage mechanism module 2, an energy storage holding mechanism module 3, an energy storage release mechanism module 4, a first transmission mechanism module 5 and a first spindle mechanism module 6.

[0049] The first spring energy storage mechanism module 2 is capable of storing energy.

[0050] The stored energy retaining mechanism module 3 can act on the first spring energy storing mechanism module 2 , so that the first spring energy storing mechanism module 2 can retain the stored energy.

[0051] The stored energy release mechanism module 4 can act on the first spring energy storage mechanism module 2 through the stored energy retaining mechanism module 3 , so that the first spring energy storage mechanism module 2 can release the stored energy.

[0052] The energy released by the first spring energy storage mechanism module 2 acts on the first spindle mechanism module 6 through the first transmission mechanism module 5 so that the first spindle mechanism module 6 can first store energy and then release energy, thereby allowing the first spindle mechanism module 6 to move between the first closing position and the second closing position.

[0053] The movement of the first spindle mechanism module 6 between the first closing position and the second closing position enables the dual power conversion switch connected to the first spindle mechanism module 6 to switch between the first power supply and the second power supply.

[0054] like Figure 1 and Fig.10 As shown, the operating mechanism 1 further includes a main shaft holding mechanism module 7 , a first closing energy release mechanism module 8 and a second closing energy release mechanism module 9 .

[0055] The spindle holding mechanism module 7 can act on the first spindle mechanism module 6, so that the first spindle mechanism module 6 can be locked in the double split position (such as Fig.10 shown).

[0056] When the first closing energy release mechanism module 8 acts on the spindle holding mechanism module 7 so that the spindle holding mechanism module 7 releases the lock on the first spindle mechanism module 6, the first spindle mechanism module 6 can move from the double open position to the first closing position, thereby closing the first power supply.

[0057] When the second closing energy release mechanism module 9 acts on the spindle holding mechanism module 7 so that the spindle holding mechanism module 7 releases the lock on the first spindle mechanism module 6, the first spindle mechanism module 6 can move from the double open position to the second closing position, thereby closing the second power supply.

[0058] like Figure 1 , Figure 2 and Figure 4 As shown, the operating mechanism further includes an electric energy storage mechanism module 10 and / or a manual energy storage mechanism module 11 .

[0059] The electric energy storage mechanism module 10 and / or the manual energy storage mechanism module 11 act on the first energy storage mechanism module 2 , so that the first energy storage mechanism module 2 stores energy.

[0060] like Fig.12 As shown, the operating mechanism includes a first movement frame 12, and the first movement frame 12 serves as a part of the overall frame of the operating mechanism.

[0061] like Fig.13 As shown, the first 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 interior of the first movement frame 12 .

[0062] like Fig.12 As shown, the electric energy storage mechanism module 10 and / or the manual energy storage mechanism module 11 are located on one side outside the first movement frame 12, while the spindle holding mechanism module 7, the first closing energy release mechanism module 8 and the second closing energy release mechanism module 9 are located on the other side outside the first movement frame 12.

[0063] 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 movement frame 12, while the spindle holding mechanism module 7, the first closing energy release mechanism module 8 and the second closing energy release mechanism module 9 are located on one side outside the first movement frame 12.

[0064] Compared to Fig.12 and Fig.13 ,like Figure 14 to Figure 15 As shown, the spindle holding mechanism module 7, the first closing energy release mechanism module 8 and the second closing energy release mechanism module 9 are removed, so that the operating mechanism is changed from three positions to two positions.

[0065] like Fig.16 and Fig.17 As shown, the operating mechanism includes at least one second movement frame 13 (for the purpose of clarity, Fig.16 Only one is shown in the figure). The second movement frame 13 serves as a part of the overall frame of the operating mechanism.

[0066] The main shaft 6 - 1 of the first main shaft mechanism module 6 and the energy storage shaft 2 - 1 - 1 of the first energy storage mechanism module 2 can pass through a plurality of second movement frames.

[0067] A second spindle mechanism module (not shown), a second spring energy storage mechanism module (not shown) and a second transmission mechanism module (not shown) are accommodated inside each second movement frame 13 .

[0068] The second spindle mechanism module, the second spring energy storage mechanism module and the second transmission mechanism module have the same construction and operating state as the first spindle mechanism module 6 , the first spring energy storage mechanism module 2 and the first transmission mechanism module 5 , respectively.

[0069] The spindle holding mechanism module 7 , the first closing energy release mechanism module 8 and the second closing energy release mechanism module 9 are located between the first movement frame 12 and the second movement frame 13 adjacent to the first movement frame 12 .

[0070] The rotation of the main shaft 6-1 of the first main shaft mechanism module 6 can drive the corresponding moving contact of the corresponding dual power conversion switch cooperating with the second main shaft mechanism module (not shown) to move between the first closing position and the second closing position, thereby making the corresponding dual power conversion switch switch between the first power supply and the second power supply, wherein a second closing spring (not shown) is provided on the second main shaft mechanism module, and the second closing spring biases the second main shaft mechanism module to the first closing position and / or the second closing position.

[0071] The second spring energy storage mechanism module includes a second opening spring (not shown), and the second spring energy storage mechanism module 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. The output part of the second spring energy storage mechanism module is connected to the second main shaft mechanism module through a second transmission mechanism module (not shown) for realizing the opening action.

[0072] 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 the second spring energy storage mechanism module locked in the storage state; and the energy storage release mechanism module 4 acts on the energy storage holding mechanism module 3, and when the energy storage release mechanism module 4 is actuated, the energy storage holding mechanism module 3 no longer keeps the second spring energy storage mechanism module locked, so that the second spring energy storage mechanism module begins to release the stored energy; wherein 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 shaft mechanism module to rotate through the second transmission mechanism module, so that the second main shaft mechanism module moves away from the first closing position or away from the second closing position.

[0073] like Figure 3 As shown, the first spring energy storage mechanism module 2 includes an energy storage shaft assembly 2-1, an energy storage actuating assembly 2-2 (which serves as the output portion of the first spring energy storage mechanism module 2) and a first opening spring 2-3.

[0074] 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.

[0075] The energy storage actuating assembly 2-2 can be rotatably mounted on the frame of the operating mechanism 1 (eg, via 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.

[0076] 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 .

[0077] The energy storage shaft assembly 2-1 includes an energy storage shaft 2-1-1 and an energy storage shaft cam 2-1-2 which is mounted on the energy storage shaft 2-1-1 and takes the energy storage shaft 2-1-1 as a rotation axis.

[0078] like Figures 5 and 6 As shown, an actuating assembly roller B is provided on the energy storage actuating assembly 2-2;

[0079] When the electric energy storage mechanism module 10 and / or the manual energy storage mechanism module 11 drives 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, thereby driving the energy storage actuating assembly 2-2 to rotate (counterclockwise).

[0080] like Figures 5 and 6 As shown, the rotation of the energy storage actuating assembly 2 - 2 causes the first opening spring 2 - 3 to compress and store energy.

[0081] like Figure 5 and Figure 6 As shown, the energy storage holding mechanism module 3 includes an energy storage holding lever 3 - 1 and a half shaft 3 - 2 .

[0082] The energy storage holding lever 3 - 1 is pivotally mounted on the frame of the operating mechanism 1 , for example, via its pivot axis 3 - 1 - 3 .

[0083] The energy storage holding lever 3 - 1 includes a first end 3 - 1 - 1 and a second end 3 - 1 - 2 .

[0084] A main shaft cam roller A is provided on the energy storage shaft cam 2-1-2.

[0085] The first end 3 - 1 - 1 of the energy storage holding lever 3 - 1 can act on the main shaft cam roller A.

[0086] The second end 3 - 1 - 2 of the energy storage holding lever 3 - 1 can act on the half shaft 3 - 2 .

[0087] like Figure 5 and Figure 6 As shown, the half shaft 3 - 2 is rotatably connected to the frame of the operating mechanism 1 .

[0088] A semicircular portion is provided on the semi-shaft 3-2, and the rotation of the semi-shaft 3-2 can block and give way to the rotation of the energy storage holding lever 3-1.

[0089] When the rotation of the half shaft 3-2 causes the semicircular portion to give way to the second end portion 3-1-2 of the energy storage holding lever 3-1, the second end portion 3-1-2 of the energy storage holding lever 3-1 can rotatably pass through the semicircular portion.

[0090] When the semicircular portion blocks the second end portion 3 - 1 - 2 of the energy storage holding lever 3 - 1 , the rotation of the second end portion 3 - 1 - 2 of the energy storage holding lever 3 - 1 is blocked by the semicircular portion.

[0091] like Figure 5 and Figure 6 As shown, the energy storage and retention mechanism module 3 also includes a lever 3 - 3 (serving as an input portion of the energy storage and retention mechanism module).

[0092] The lever 3 - 3 is rotatably mounted on the frame of the operating mechanism 1 , for example via its pivot axis 3 - 3 - 1 .

[0093] The lever 3-3 can 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.

[0094] After the first opening spring 2-3 completes the compression energy storage (at Figure 6 In the embodiment, the first opening spring 2-3 is in the under-dead point position), the main shaft 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, the semicircular portion blocks the second end 3-1-2 of the energy storage holding lever 3-1, and the first end 3-1-1 of the energy storage holding lever 3-1 blocks the rotational torque caused by the actuating assembly roller B on the energy storage shaft cam 2-1-2 and does not cause the energy storage shaft cam 2-1-2 to rotate (the energy storage actuating assembly 2-2 also does not rotate), thereby preventing the first opening spring 2-3 from stretching and releasing energy.

[0095] The stored energy release mechanism module 4 includes a stored energy release electromagnetic driver, which has a release electromagnetic coil 4 - 1 and an electromagnetic coil moving iron core 4 - 2 (as an output part of the stored energy release mechanism module 4 ).

[0096] like Figures 6 to 8 As shown, 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 moving iron core 4-2 acts on the lever 3-3, and the lever 3-3 can act on the half shaft 3-2, so that the semicircular portion of the half shaft 3-2 will not block the second end 3-1-2 of the energy storage holding lever 3-1 through rotation, and the rotation of the energy storage holding lever 3-1 makes its first end 3-1-1 not block the main shaft cam roller A and will not block the rotational torque caused by the actuating assembly roller B acting on the energy storage shaft cam 2-1-2, thereby making the energy storage holding lever 3-1 not limit the extension energy release of the first opening spring 2-3, and the extension energy release of the first opening spring 2-3 drives the rotation of the energy storage actuating assembly 2-2, and the actuating assembly roller B moves into the recessed portion of the gear profile of the energy storage shaft cam 2-1-2 (as shown in FIG. Figure 8 shown).

[0097] The energy storage release mechanism module 4 can be set on any side or above and below the energy storage retention mechanism module 3. At the same time, the output part of the energy storage release mechanism module 4 is coordinated with the input part of the energy storage retention mechanism module 3 to drive and unlock the energy storage retention mechanism module 3 when the energy storage release mechanism module 4 is actuated.

[0098] The expansion and energy release of the first opening spring 2-3 drives the energy storage actuating assembly 2-2 to move.

[0099] The movement of the energy storage actuating assembly 2 - 2 causes the first spindle mechanism module 6 to rotate from the first closing position or the second closing position to the double opening position through the transmission mechanism module.

[0100] like Fig.10 As shown, the first spindle mechanism module 6 includes a spindle 6-1 and a spindle crank arm 6-2 and a spindle locking tongue 6-3 fixedly mounted on the spindle 6-1.

[0101] The spindle holding mechanism module 7 includes a first locking member 7 - 1 and a second locking member 7 - 2 .

[0102] Through the relative movement between the first locking member 7-1 and the second locking member 7-2, an openable and closable locking opening 7-3 is formed between the first locking end of the first locking member 7-1 and the second locking end of the second locking member 7-2.

[0103] During the movement of the first spindle mechanism module 6 between the first closing position and the second closing position, the locking mouth 7-3 can receive the spindle locking tongue 6-3 and maintain the spindle locking tongue 6-3 between the first locking end of the first locking member 7-1 and the second locking end of the second locking member 7-2, so as to lock the first spindle mechanism module 6 in a double open position between the first closing position and the second closing position.

[0104] like Figure 7 As shown, the spindle crank arm 6-2 includes a first driven portion 6-2-1 and a second driven portion 6-2-2, both of which can be formed as protrusions at appropriate locations of the spindle crank arm 6-2, etc., for being driven by the transmission mechanism module 5 according to the present invention.

[0105] The first transmission mechanism module 5 comprises: a driving member 5-1, which can move between an initial position and a driving position and comprises a first driving portion 5-1-1 and a second driving portion 5-1-2.

[0106] like Figure 7 As shown, when the first spindle mechanism module 6 is in the first closing position, through the movement of the driving member 5-1 from the initial position to the driving position, the first driving part 5-1-1 drives the first driven part 6-2-1 to make the first spindle mechanism module 6 move from the first closing position to the second closing position.

[0107] When the first 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 through the movement of the driving member 5-1 from the initial position to the driving position, so that the first spindle mechanism module 6 moves from the second closing position to the first closing position.

[0108] According to the present invention, since the spindle crank arm 6-2 is in different positions when it is in the first closing position and the second closing position, the positions of the first driven part 6-2-1 and the second driven part 6-2-2 will also change accordingly. Therefore, by reasonably setting the positions of the first driven part 6-2-1 and the second driven part 6-2-2 on the spindle crank arm 6-2, it can be achieved that the spindle crank arm 6-2 is in a state of being driven by different driven parts when it is in different positions. When the first 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.

[0109] When the first 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 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.

[0110] With this arrangement, when the spindle crank arm 6-2 is in any position, the driving member 5-1 can drive the corresponding driven part only by unidirectional movement toward the driving position, so that the spindle crank arm 6-2 moves toward another position.

[0111] Compared with the complicated prior art of respectively setting two sets of driving devices for movement toward two positions or setting a complicated bidirectional driving mechanism module in one set of driving device, the present invention can realize the dual-position drive of the spindle crank arm 6-2 by only setting a single driving member 5-1 capable of unidirectional movement.

[0112] It should be understood that the “unidirectional movement” in this article means that the driving direction of the driving member 5 - 1 is unidirectional, but the driving member 5 - 1 can still return to the initial position.

[0113] The driving member 5-1 is configured as follows: after the first driving part 5-1-1 drives the first driven part 6-2-1 and reaches the driving position of the driving member 5-1, the main shaft mechanism module 6 is locked in the double-open position, and with the unlocking action of the second closing energy release mechanism module 9, the main shaft mechanism module 6 continues to move toward the second closing position, and the second driven part 6-2-2 applies a force to the second driving part 5-1-2 to urge the driving member 5-1 to return to the initial position; after the second driving part 5-1-2 drives the second driven part 6-2-2 and reaches the driving position of the driving member 5-1, with the unlocking action of the first closing energy release mechanism module 8, the main shaft mechanism module 6 continues to move toward the first closing position, and the first driven part 6-2-1 applies a force to the first driving part 5-1-1 to urge the driving member 5-1 to return to the initial position.

[0114] The first driven part 6-2-1 and / or the second driven part 6-2-2 include rollers. By providing the rollers, the interaction between the first and second driving parts and the first and second driven parts can be improved, the friction can be reduced, and the movement between them can be smoother.

[0115] The first spindle mechanism module 6 also includes a first closing spring 6 - 4 .

[0116] During the process of the first driving part 5-1-1 driving the first driven part 6-2-1, the first closing spring 6-4 stores energy. With the unlocking action of the second closing energy release 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 spindle mechanism module 6 to the second closing position.

[0117] In the process of the second driving part 5-1-2 driving the second driven part 6-2-2, the first closing spring 6-4 stores energy. With the unlocking action of the first closing energy release 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 spindle mechanism module 6 to the first closing position.

[0118] like Fig. 9 As shown, the first closing spring 6-4 is configured as a compression spring and is pivotally connected to one end of the main shaft arm 6-2, and when the driving member 5-1 reaches the driving position, the compression spring is at a dead point position.

[0119] like Figure 7 As shown, the driving member 5 - 1 has a pivot 5 - 2 , and the driving member 5 - 1 performs a rotational movement around the pivot 5 - 2 between an initial position and a driving position.

[0120] The driving member 5-1 is formed as a plate-like member, a portion of its outer contour serves as a first driving portion 5-1-1, and another portion of its outer contour serves as a second driving portion 5-1-2.

[0121] The energy storage actuating assembly 2-2 can move between an initial position and an actuating position.

[0122] The energy storage actuating assembly 2 - 2 causes the driving member 5 - 1 to move from the initial position to the driving position during the process of moving from the initial position to the actuating position.

[0123] The first transmission mechanism module 5 further comprises a transmission member 5-3, which is pivotally connected to the driving member 5-1 via a pivot 5-4 and has a first end 5-3-1 and a second end 5-3-2 on both sides of the pivot 5-4.

[0124] The first end 5-3-1 is movably arranged in the slide groove 5-1-3 on the driving member 5-1, and the second end 5-3-2 can move along the first contour 2-2-2 of the energy storage actuating component 2-2 when the energy storage actuating component 2-2 moves from the initial position to the actuating position, so that the energy storage actuating component 2-2 causes the driving member 5-1 to move from the initial position to the driving position through the transmission member 5-3.

[0125] The driving member 5-1 includes a return spring (not shown) that enables the driving member 5-1 to return from the driving position to the initial position, and the return spring is connected to the first end 5-3-1 of the transmission member 5-3.

[0126] During the movement of the energy storage actuating assembly 2-2 from the initial position to the actuating position, the first profile 2-2-2 applies a first torque around the pivot 5-4 of the transmission member 5-3 to the second end 5-3-2, so that the first end 5-3-1 of the transmission member 5-3 remains against the end of the slide slot 5-1-3.

[0127] like Figure 7 As shown, the energy storage actuating assembly 2-2 further includes a second profile 2-2-3 continuing from the first profile 2-2-2.

[0128] After the energy storage actuating assembly 2-2 reaches the actuating position, the second end 5-3-2 of the driving member 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.

[0129] When the second end 5-3-2 of the transmission member 5-3 moves to the part of the second profile 2-2-3 connected to the first profile 2-2-2, the connected part applies a second torque around the pivot 5-4 of the transmission member 5-3 to the second end 5-3-2, so that the second end 5-3-2 of the transmission member 5-3 moves along the second profile 2-2-3, and the second torque is opposite to the first torque.

[0130] During the process of the stored-energy actuating assembly 2-2 returning from the actuating position to the initial position, the second profile 2-2-3 of the stored-energy actuating assembly 2-2 moves away from the second end 5-3-2 of the transmission member 5-3.

[0131] 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 member 5-3, the return spring continues to contract and rotates the transmission member 5-3 around its pivot 5-4 so that the second end 5-3-2 of the transmission member 5-3 returns to the first profile 2-2-2 of the energy storage actuating assembly 2-2.

[0132] The energy storage shaft assembly 2 - 1 can release stored energy to the energy storage actuating assembly 2 - 2 to move the energy storage actuating assembly 2 - 2 from an initial position to an actuating position.

[0133] like Figure 5 As shown, the first opening spring 2-3 has 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.

[0134] like Figure 6 As shown, the electric energy storage mechanism module 10 and / or the manual energy storage mechanism module 11 drives the energy storage shaft 2-1-1 to rotate counterclockwise (to store energy), and 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 rotate counterclockwise (from the actuating position to the initial position), and the energy storage actuating assembly 2-2 compresses the first opening spring 2-3 through 2-3-2 to store energy.

[0135] During the movement of the first spindle mechanism module 6 from the first closing position to the second closing position, the spindle locking tongue 6-3 applies a first opening action to the first locking member 7-1 to fully open the locking opening 7-3.

[0136] During the movement of the first spindle mechanism module 6 from the second closing position to the first closing position, the spindle locking tongue 6-3 applies a second opening action to the second locking member 7-2 to fully open the locking opening 7-3.

[0137] During the first opening action, after the first locking member 7-1 moves to its extreme position, the first locking member 7-1 causes the spindle locking tongue 6-3 to perform a first return action toward the locking position.

[0138] During the second opening action, after the second locking member 7-2 moves to its extreme position, the second locking member 7-2 causes the spindle lock tongue 6-3 to perform a second return action toward the locking position.

[0139] The first locking member 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 member 7-1 that tends to cause the first locking member 7-1 to close the locking opening 7-3.

[0140] The second locking member 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 member 7-2 that tends to cause the second locking member 7-2 to close the locking opening 7-3.

[0141] The first locking member 7-1 is configured to be pivotable about the first pivot 7-1-2, and the torque applied by the spindle lock tongue 6-3 to the first locking end is in the same direction as the torque applied by the first biasing mechanism module 7-1-1 of the first locking member 7-1 to the first locking member 7-1.

[0142] The second locking member 7-2 is configured to be pivotable around the second pivot 7-2-2, and the torque applied by the spindle lock tongue 6-3 to the second locking end is in the same direction as the torque applied by the second biasing mechanism module 7-2-1 of the second locking member 7-2 to the second locking member 7-2.

[0143] 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, the center of which is not concentric with the rotation center of the second pivot 7-2-2.

[0144] The first locking member 7 - 1 includes a first free end, and 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 spindle holding mechanism module 7 .

[0145] As shown in Figure 11, the first closing energy release mechanism module 8 is configured as a first electromagnetic driver, which has a first electromagnetic coil 8-1 and a first moving iron core 8-2 (as the output part of the first closing energy release mechanism module 8) at the second free end of the second locking member 7-2. The movement of the first moving iron core 8-2 causes the second locking member 7-2 to move away from the main shaft lock tongue 6-3 and give way. The main shaft lock tongue 6-3 is pushed by the first locking member 7-1 to make the first closing spring 6-4 pass the dead point, and the first closing spring 6-4 releases energy, thereby causing the main shaft mechanism module 6 to rotate from the double-open position to the first closing position, and the second locking member 7-2 is reset.

[0146] The first electromagnetic drive can be arranged on the lower side (as shown in Figure 11) or the side (left side or right side, not shown) of the second locking member 7-2, so that the movement of the first moving iron core 8-2 can cause the second locking member 7-2 to move away from the main shaft lock tongue 6-3 and give way.

[0147] like Figure 1As shown, the second closing energy release mechanism module 9 is configured as a second electromagnetic driver, which has a second electromagnetic coil 9-1 and a second moving iron core 9-2 (as the output part of the second closing energy release mechanism module 9) that can actuate the first free end of the first locking member 7-1. The movement of the second moving iron core 9-2 causes the first locking member 7-1 to move away from the main shaft lock tongue 6-3 and give way. The main shaft lock tongue 6-3 is pushed by the second locking member 7-2 to make the first closing spring 6-4 pass the dead point, and the first closing spring 6-4 releases energy, thereby causing the main shaft mechanism module 6 to rotate from the double-open position to the second closing position, and the first locking member 7-1 is reset.

[0148] The second electromagnetic driver can be arranged on the upper side of the first locking member 7-1 (eg Figure 1 ) or side (left or right, not shown), so that the second moving iron core 9-2 moves to enable the first locking piece 7-1 to move away from the main shaft lock tongue 6-3 and give way.

[0149] That is to say, the first closing energy release mechanism module 8 and the second closing energy release mechanism module 9 can be arranged on any side or above and below the spindle holding mechanism module 7, and at the same time, the output parts of the first closing energy release mechanism module 8 and the second closing energy release mechanism module 9 are kept in coordination with the input part of the spindle holding mechanism module 7.

[0150] According to the above embodiment of the present disclosure, the principle and operation process of the operating mechanism with three stations are as follows:

[0151] 1. Energy storage of the first opening spring: electric energy storage mechanism module and / or manual energy storage mechanism module → energy storage of the first opening spring (+ energy storage holding mechanism module locks the first opening spring);

[0152] 2. Opening: the energy storage release mechanism module actuates → the energy storage holding mechanism module unlocks the first opening spring → the first opening spring releases energy → the first transmission mechanism module → the main shaft of the first main shaft mechanism module (+ the first closing spring stores energy + the main shaft holding mechanism module locks the main shaft of the first main shaft mechanism module) → the breaking unit opens (double opening position);

[0153] 3. Closing of the first power supply S1: the first closing release mechanism module is actuated → the spindle holding mechanism module is tripped toward S1 → the first closing spring releases energy → the spindle of the first spindle mechanism module rotates toward S1 → the disconnecting unit is closed (first closing position); or

[0154] The second power supply S2 is closed: the second closing energy release mechanism module is actuated → the spindle holding mechanism module is tripped toward S2 → the first closing spring releases energy → the spindle of the first spindle mechanism module rotates toward S2 → the disconnecting unit is closed (the second closing position).

[0155] According to the above embodiment of the present disclosure, by removing the spindle holding mechanism module and the first and second closing release mechanism modules, the three-station operation mechanism can be changed into a two-station operation mechanism, and its principle and operation process are as follows (taking the closing of the first power source S1 to the closing of the second power source S2 as an example):

[0156] 1. First opening spring energy storage: electric energy storage mechanism module and / or manual energy storage mechanism module →

[0157] The first opening spring stores energy (+ the energy storage holding mechanism module locks the first opening spring);

[0158] 2. Conversion: The energy storage release mechanism module actuates → the energy storage holding mechanism module unlocks the first opening spring → the first opening spring releases energy → the first transmission mechanism module → the main shaft of the first main shaft mechanism module (+ the first closing spring directly releases energy after storing energy and drives the main shaft of the first main shaft mechanism module to continue rotating) → the disconnecting unit switches from S1 to S2 (switching from the first closing position to the second closing position).

[0159] According to the above embodiment of the present disclosure, the first closing spring has two energy release positions in different directions (corresponding to the first closing position and the second closing position, respectively) and a dead point position (double-open position), and the dead point position is held and controlled by a set of "spindle holding mechanism modules" + two sets of "closing energy release mechanism modules" to control the release direction. Therefore, in this solution, a set of first closing springs can correspond to three working positions.

[0160] According to the above embodiments of the present disclosure, the first opening spring can store energy in advance, and it has greater energy. When released, it drives the disconnecting unit to open and stores energy for the closing spring. This process is fast, so after opening, it can be closed quickly, which is conducive to the rapid conversion of the dual power conversion switch.

[0161] According to another embodiment of the present disclosure, a dual power transfer switch is provided, wherein the dual power transfer switch includes the above operating mechanism.

[0162] 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 shaft holding mechanism module / the first closing energy release mechanism module / the second closing energy release mechanism module / the energy storage release mechanism module can be flexibly arranged.

[0163] According to the content of the present disclosure, the structure of the original single movement frame can be expanded into a multi-movement frame structure (i.e., two sets of transmission mechanism modules / energy storage mechanism modules / spindle mechanism modules), and only one set of corresponding holding mechanism modules and corresponding release mechanism modules (spindle holding mechanism module / first closing energy release mechanism module / second closing energy release mechanism module / energy storage release mechanism module / energy storage holding mechanism module) is required, and the spindle of the first spindle mechanism module and the energy storage shaft of the first energy storage mechanism module can pass through multiple movement frames to ensure motion synchronization and control synchronization. Through such layout changes, it can be easily upgraded to a mechanism module with a larger operating power, such as a three-station TSE with a rated current of 4000A.

[0164] 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 may be made in light of the above disclosure or may be acquired from practice of the embodiments.

[0165] Even though particular combinations of features are recited in the claims and / or disclosed in the specification, these combinations are not intended to limit the disclosure of the various embodiments. In fact, many of these features may be combined in ways not specifically recited in the claims and / or disclosed in the specification. Although each dependent claim listed below may only directly depend on one claim, the disclosure of the various embodiments includes each dependent claim in combination with every other claim in the claim set.
