Description

Dual-power change-over switch and operating mechanism thereof

Technical Field

Embodiments of the present disclosure relate generally to the field of electrical equipment technology, and more particularly, to an operating mechanism for a dual power transfer switch and a dual power transfer switch.

Background

A dual power Transfer Switch (TSE) is an important electrical appliance switch, and is widely used in hospitals, airports, fire protection and other important loads that are not allowed to be powered off. An operating mechanism is arranged inside the dual-power transfer switch. The switching of the working modes is completed by driving different trigger pieces in the operating mechanism, so that the dual-power transfer switch is connected or disconnected with different power supply ends.

However, since the common trigger pieces are scattered at different positions, the trigger pieces need to be operated at different positions when the working mode of the dual-power transfer switch needs to be switched, which is disadvantageous for centralized operation, and thus causes the problem of complex operation of the dual-power transfer switch.

Fig. 1 is a schematic view showing a part of the structure of a conventional dual power transfer switch 100; fig. 2 shows a schematic diagram of the operation of the breaking unit 5 of a conventional dual power transfer switch 100, in which the dual power transfer switch 100 is switched between a dual-division position, a first power-on position, and a second power-on position. As shown in fig. 1 to 2, the conventional dual power transfer switch 100 includes a moving assembly 3, a breaking assembly 4, and a breaking unit 5. The breaking unit 5 includes a moving contact 51, a first fixed contact 52, and a second fixed contact 53. The first and second stationary contacts 52 and 53 are respectively connected to the first and second power sources. The double power switch 100 can be switched among the double-split position, the first power position, and the second power position by connecting or not connecting the movable contact 51 with different fixed contacts.

Specifically, the moving assembly 3 is connected with the breaking unit 5. The moving assembly 3 can drive the moving contact 51 of the breaking unit 5 to move, so as to enable the dual power transfer switch 100 to be switched from the dual-breaking position to the first power-on position or the second power-on position. Fig. 3 shows a schematic diagram of the mobile assembly 3 according to fig. 1, wherein the dual power transfer switch 100 is in a dual position. As shown in fig. 3, the moving assembly 3 includes a first moving portion 31, a second moving portion 32, a first moving shaft 33, a second moving shaft 34, a stopper 35, a closing spring 36, a latch 37, a transmission gear 38, and a holder 39.

In some embodiments, the first moving portion 31 and the second moving portion 32 are rotatably connected. The first moving portion 31 is provided with a first movable hole 311, and the first moving shaft 33 is provided in the first movable hole 311. The closing spring 36 is provided on the outer side surface of the first moving portion 31. The stopper 35 is provided on the outer side surface of the first moving portion 31 and is located between the closing spring 36 and the first moving shaft 33. The second moving portion 32 is provided with a second moving shaft 34 therein and is rotatable about the second moving shaft 34. The lock tongue 37 is disposed at an end of the second moving portion 32 near the holding member 39, and the transmission gear 38 is disposed at an end of the second moving portion 32 far from the holding member 39. The number of the holding pieces 39 is two. With the dual power switch 100 in the dual position, the two clamps 39 clamp the tongue 37, thereby disabling movement of the mobile assembly 3. In the case where it is necessary to switch the double power switch 100 from the double-split position to the first power position or the second power position, it is necessary to disengage the different clip 39. The clamping member 39 includes a clamping portion 391, a clamping shaft 392, and a clamping spring 393. The clamping shaft 392 passes through the clamping portion 391, and the clamping portion 391 is rotatable about the clamping shaft 392. The clamping springs 393 are connected at opposite ends to the two clamping portions 391, respectively.

Fig. 4 shows a schematic view of the moving assembly 3 according to fig. 3 from another perspective, with the closing spring 36 in the dead-center position; fig. 5 shows a schematic diagram of the mobile assembly 3 according to fig. 1, wherein the dual power transfer switch 100 is in a first power position; fig. 6 shows a schematic diagram of the mobile assembly 3 according to fig. 1, wherein the dual power transfer switch 100 is in a second power position. As shown in fig. 4 and 5, the clamping portion 391 at the upper end is driven to rotate counterclockwise around the clamping shaft 392, and the lock tongue 37 is unlocked. The lower clamping portion 391 moves toward the other clamping portion 391 under the urging of the clamping spring 393. The clamping portion 391 at the lower end applies a force to the lock tongue 37 to move the closing spring 36 beyond the dead point position, and the second moving portion 32 rotates counterclockwise to simultaneously rotate the transmission gear 38 counterclockwise. The transmission gear 38 drives the breaking unit 5 to rotate, so that the first fixed contact 52 connected with the first power supply is connected with the moving contact 51, and finally the dual-power transfer switch 100 is switched from the dual-division position to the first power-on position.

As shown in conjunction with fig. 4 and 6, in the process of switching the dual power conversion switch 100 from the dual-division position to the second power-on position is similar to the process of switching from the dual-division position to the first power-on position, the embodiments of the present disclosure will not be repeated.

In some embodiments, the brake release assembly 4 is connected to the movement assembly 3. The opening assembly 4 can move to unlock the moving assembly 3 and drive the moving assembly 3 to move, so that the dual power switch 100 is switched from the first power position or the second power position to the dual position. Fig. 7 shows a schematic structural view of the switching-off assembly 4 and the moving assembly 3 according to fig. 1, wherein the dual power transfer switch 100 is in a first power-on position; fig. 8 shows a schematic structural view of the breaking assembly 4 and the moving assembly 3 according to fig. 7, viewed from another angle of view. As shown in fig. 7 to 8, the brake release assembly 4 includes a button 41, a lever 42, a half shaft 43, a lever 44, a first cam 45, a mounting member 46, a second cam 461, a roller 462, a push plate 47, and a telescopic member 48, and the second cam 461 and the roller 462 are mounted on the mounting member 46.

Continuing to refer to fig. 8, the button 41 is rotated clockwise, the button 41 drives the shift lever 42 to rotate anticlockwise, and the shift lever 42 drives the half shaft 43 to rotate clockwise so that the half shaft 43 releases the limit of the lever 44, and the lever 44 rotates clockwise. The lower end of the lever 44 releases the restriction of the first cam 45, and the first cam 45 releases the restriction of the roller 462 and the second cam 461. The expansion member 48 releases the energy and pushes the second cam 461 to rotate clockwise. The second cam 461 drives the push plate 47 to rotate clockwise, the push plate 47 pushes the first limiting part 321 on the second moving part 32 and drives the transmission gear 38 to rotate anticlockwise, and the transmission gear 38 drives the moving contact 51 to be separated from the first fixed contact 52, so that the dual-power transfer switch 100 is finally switched from the first power-on position to the dual-split position. It should be noted that, after the dual power switch 100 reaches the dual position, the latch 37 is locked again by the two clamping members 39, so that the dual power switch 100 is maintained in the dual position.

In some embodiments, the second limiting member 322 in the second moving portion 32 is disposed close to the first moving portion 31 with respect to the first limiting member 321. When the double power switch 100 is switched from the second power position to the double position, the movement states of the push button 41, the lever 42, the half shaft 43, the lever 44, the first cam 45, the mount 46, the second cam 461, the roller 462, the push plate 47, and the expansion member 48 are the same as the movement states of the double power switch 100 from the first power position to the double position. The difference is that the push plate 47 pushes the second limiting member 322 and drives the transmission gear 38 to rotate clockwise, and the transmission gear 38 drives the moving contact 51 to be separated from the second fixed contact 53, so that the dual power switch 100 is switched from the second power-on position to the dual-split position.

As described hereinabove, in switching the dual power switch 100 in the dual position, the first power position, and the second power position, it is necessary to activate the button 41 or the two clamping portions 391, respectively. Since the button 41 and the two clamping portions 391 are dispersed at different positions, it is necessary to operate at different positions in the case of switching the operation mode of the dual power conversion switch 100, and thus the centralized operation is disadvantageous, thereby causing a problem in that the operation of the dual power conversion switch 100 is complicated.

To solve the above technical problems, an embodiment of the present disclosure provides a dual power transfer switch 100, where the dual power transfer switch 100 includes an operating mechanism, a moving assembly 3, a breaking assembly 4, and a breaking unit 5. The operating mechanism is respectively connected with the moving component 3 and the separating brake component 4. The moving assembly 3 and the opening assembly 4 can move along with the operating mechanism, so that the dual-power transfer switch of the embodiment of the disclosure can complete the switching of the dual-power transfer switch 100 among the dual-dividing position, the first power-on position and the second power-on position through the operating mechanism, and the operation steps of the dual-power transfer switch 100 are simplified. Such a dual power transfer switch 100 will be described below with reference to fig. 9 to 14.

The dual power transfer switch 100 in the embodiment of the present disclosure has the same structure and operation principle as the moving assembly 3, the breaking assembly 4, and the breaking unit 5 in the above-described embodiment. The dual power transfer switch 100 of the embodiment of the present disclosure is mainly different in structure from the dual power transfer switch 100 of the above-described embodiment in that an operating mechanism is added. Hereinafter, differences between the dual power conversion switch 100 in the embodiment of the present disclosure and the dual power conversion switch 100 of the above-described embodiment will be described in detail, and the same parts will not be described in detail.

In some embodiments, fig. 9 illustrates a partial schematic diagram of a dual power transfer switch 100 according to some embodiments of the present disclosure. As shown in fig. 9, the operating mechanism includes a control assembly 1 and a trigger assembly 2. The control assembly 1 is connected with the moving assembly 3. The control assembly 1 can drive the moving assembly 3 to move, so that the dual power transfer switch 100 can be switched from the dual-split position to the first power-on position or the second power-on position. The triggering assembly 2 is spaced apart from the control assembly 1 and is connected to the brake release assembly 4. The control assembly 1 is able to move towards the trigger assembly 2 and to push the trigger assembly 2 into motion. The triggering component 2 drives the opening component 4 to move so as to unlock the moving component 3 by the opening component 4. After the unlocking, the opening assembly 4 drives the moving assembly 3 to move, so that the dual-power transfer switch 100 can be switched from the first power-on position or the second power-on position to the dual-split position.

In some embodiments, fig. 10 shows a schematic structural view of the control assembly 1, the trigger assembly 2, the clamping member 39 and the push button 41 according to fig. 9, wherein the second actuating member 13 is in the home position; fig. 11 illustrates a schematic structural view of the control assembly 1 and the clamp 39 according to some embodiments of the present disclosure, wherein the second actuator 13 is in the first position; fig. 12 shows a schematic structural view of the control assembly 1 according to some embodiments of the present disclosure, wherein the transmission 15 is not shown. As shown in fig. 10 to 12, the control assembly 1 includes a first actuator 11, a first pin 12, a second actuator 13, and a second pin 14. The first actuator 11 and the second actuator 13 are rotatably connected by a first pin 12. The second pin 14 passes through the second actuator 13, and the second actuator 13 is rotatable about the second pin 14 to enable the second actuator 13 to be switched between the home position, the first position, and the second position. In the case where the second actuator 13 is switched from the home position to the first position, the dual power changeover switch 100 is switched from the dual position to the first power on position. In the case where the second actuator 13 is switched from the home position to the second position, the dual power changeover switch 100 is switched from the dual position to the second power on position.

As further shown in fig. 10 and 12, in some embodiments, the axis of the first pin 12 and the axis of the second pin 14 are disposed perpendicular or oblique to each other. With the above arrangement, on the one hand, the first actuator 11 is enabled to rotate the second actuator 13 about the second pin 14. On the other hand, the first actuator 11 can rotate about the first pin 12 and relative to the second actuator 13, with the second actuator 13 always in the home position.

In some embodiments, with the second actuating member 13 in the home position, both ends of the second actuating member 13 are connected to one ends of the pair of transmission members 15, respectively. The other ends of the pair of transmission members 15 are respectively connected with corresponding clamping members 39. As shown in fig. 10 to 11, the second actuator 13 is rotated clockwise, and the second actuator 13 is switched from the original position to the first position and drives the upper end transmission member 15 to rotate counterclockwise. The upper end driving member 15 rotates the clamping member 39 connected thereto. The clamp 39 releases the lock of the latch 37, and the dual power switch 100 can be moved to the first power position. The second actuating member 13 is rotated counterclockwise, the second actuating member 13 is switched from the original position to the second position, and the transmission member 15 at the lower end is driven to rotate clockwise. The transmission member 15 at the lower end drives the clamping member 39 connected with the transmission member to rotate, the clamping member 39 releases the lock of the lock tongue 37, and the dual-power transfer switch 100 can move to the second power-on position.

Specifically, as shown in fig. 10, each transmission member 15 includes a main body portion 151 and a transmission shaft 152. The transmission shaft 152 passes through the main body 151 and the main body 151 is rotatable around the transmission shaft 152. When the second actuator 13 is in the home position, both ends of the second actuator 13 are connected to the corresponding main body portions 151, respectively, and the other ends of the main body portions 151 are connected to the corresponding clip 39, respectively. With the above configuration, the second actuator 13 is rotated, and the second actuator 13 rotates the main body 151 around the transmission shaft 152. The end of the main body 151 away from the second actuating member 13 drives the clamping member 39 connected thereto to rotate, so that the clamping member 39 releases the lock of the latch 37, and the dual power switch 100 can move to the first power position or the second power position.

As shown in fig. 11, in some embodiments, each transmission member 15 further includes a resilient portion 153. The elastic portion 153 is connected to an end of the main body portion 151 remote from the second actuating member 13. When the second actuating member 13 is in the first position or the second position, the elastic portion 153 is pulled, and the elastic portion 153 can drive the main body portion 151 to rotate around the transmission shaft 152, so that the second actuating member 13 is reset from the first position or the second position to the original position, and the second actuating member 13 can rotate towards the trigger assembly 2 and push the trigger assembly 2 under the condition of the original position.

The elastic portion 153 according to the embodiment of the present disclosure may be various types of elastic portions 153 currently known or available in the future, and the embodiment of the present disclosure is not limited thereto. For example, in some embodiments, the resilient portion 153 is a spring.

Returning to fig. 10, in some embodiments, the trigger assembly 2 includes a trigger portion 21 and a trigger shaft 22, the trigger shaft 22 passing through the trigger portion 21 and the trigger portion 21 being rotatable about the trigger shaft 22. With the second actuator 13 in the home position, one end of the trigger 21 is spaced apart from the first actuator 11, and the other end of the trigger 21 is connected to the button 41. With the second actuator 13 in the home position and the first actuator 11 rotated toward the trigger assembly 2, the first actuator 11 pushes the trigger 21 to rotate. The trigger part 21 pushes the button 41 of the opening assembly 4 to rotate, so that the opening assembly 4 can move to release the lock of the moving assembly 3 and drive the moving assembly 3 to move, so that the dual power switch 100 can be switched from the first power position or the second power position to the dual-split position.

In some embodiments, fig. 13 shows a schematic structural view of the control assembly 1, the trigger assembly 2, and the button 41 according to some embodiments of the present disclosure, wherein the transmission 15 is not shown. As shown in connection with fig. 12 to 13, the first actuating member 11 is provided with a protruding member 16, and the protruding member 16 pushes the trigger portion 21 to rotate in the case where the second actuating member 13 is in the home position and the first actuating member 11 rotates toward the trigger assembly 2.

Returning to fig. 12, the end of the first actuator 11 remote from the second actuator 13 is a circular arc plate 111, and the center of the arc in the circular arc plate 111 faces the second actuator 13. The arc plate 111 is made of an insulating material. With the above configuration, the arc plate 111 is always attached to the panel of the dual power switch 100 during the movement of the first actuator 11, so as to avoid the exposure of the internal parts of the operating mechanism, thereby improving the insulation level of the dual power switch 100.

Continuing back to fig. 12, the side of the circular arc plate 111 facing away from the second actuator 13 is provided with a mounting groove 112. On the one hand, an operation lever (not shown in the drawings) can be provided in the mounting groove 112, by which the first actuator 11 can be conveniently operated. On the other hand, in the case of removing the operation lever, the mounting groove 112 can also prevent the internal parts of the operation mechanism from being exposed, thereby improving the insulation level of the dual power conversion switch 100.

Fig. 14 illustrates a schematic view of the movement of the first actuator 11 according to some embodiments of the present disclosure. As shown in fig. 14, the first actuator 11 can move vertically upward, vertically downward, or horizontally rightward along an arrow. It will be appreciated that during the vertical upward movement or the vertical downward movement of the first actuator 11 along the arrow, no relative rotation occurs between the second actuator 13 and the first actuator 11. Fig. 15 shows a schematic view of the movement of the first actuator 11 according to further embodiments of the present disclosure. As shown in fig. 15, the first actuator 11 can move obliquely upward, obliquely downward, or horizontally rightward along the arrow. It will be appreciated that during movement of the first actuator 11 diagonally upward or diagonally downward along the arrow, the first actuator 11 rotates relative to the second actuator 13.

The operating mechanism according to the embodiment of the present disclosure may be applied to various dual power transfer switches 100 so as to be capable of being centrally operated in the case where the operation mode of the dual power transfer switch 100 needs to be switched, thereby solving the problem of complicated operation of the dual power transfer switch 100.
