Description

[Technical Field]

[0001] The present invention relates to the technical field of circuit breakers, and in particular to electrical operating devices for circuit breakers. [Background technology]

[0002] Existing communication cabinets or high-performance control cabinets must all be equipped with automatic control and remote control functions. For convenience, they generally use contact devices for control. However, due to the low frequency of operation, using contact devices has the disadvantage of high energy consumption and high costs. Replacing the contact devices with electrically operated circuit breakers requires the installation of electrical operating devices, which increases costs. Therefore, devising a device that allows one electrical operating mechanism to control multiple handles of multiple miniature circuit breakers by combining other mounting devices is essential to achieving energy consumption and cost reductions for communication cabinets or high-performance control cabinets.

DETAILED DESCRIPTION OF THE INVENTION

[0025] Specific embodiments of the electrical operating device for a circuit breaker of the present invention will now be further described in conjunction with the examples given in Figures 1 to 20. The electrical operating device for a circuit breaker of the present invention is not limited to the description of the following examples.

[0026] As shown in Figures 1-5, the electrical operating device of the circuit breaker has a first slide groove 101 on one side wall of its housing 1 as an operating surface 11, and the first slide groove 101 faces the handle 5 of the circuit breaker. A driving member for moving the handle 5 of the circuit breaker to turn the switch on or off is provided inside the housing 1, and a slide bar 102 is attached to the inside of the housing 1, and the driving member is attached to the slide bar 102. The driving member protrudes from the first slide groove 101 to the outside of the housing 1, and moves along the first slide groove 101 under the operation of a transfer mechanism inside the housing 1, so as to actuate the handle 5 of the circuit breaker to turn the switch on or off.

[0027] The driving member includes a switch-on operation unit 31a and a switch-off operation unit 31b. As shown in FIG. 3, in the initial state, there is a space between the switch-on operation unit 31a and the switch-off operation unit 31b of the driving member. The switch-on operation unit 31a is located below the switch-off operation unit 31b, and the circuit breaker handle 5 extends into that space. As shown in FIG. 4, when the circuit breaker needs to be switched on, the transfer mechanism moves the switch-on operation unit 31a upward along the first slide groove 101 and pushes the circuit breaker handle 5 upward to switch it on. As shown in FIG. 5, when the circuit breaker needs to be switched off, the transfer mechanism moves the switch-off operation unit 31b downward and pushes the circuit breaker handle 5 downward to switch it off. If the vertical arrangement were relative, it is of course possible that the switch-off operation unit 31b would be located below the switch-on operation unit 31a and the switch-off operation unit 31b would move upward to push the circuit breaker handle 5 to switch it off. Preferably, in the initial state, i.e., when no switching on / off is performed, neither the switch-off operating unit 31b nor the switch-on operating unit 31a comes into contact with the circuit breaker handle 5, and after the switch-off operating unit 31b or the switch-on operating unit 31a operates the circuit breaker handle, the circuit breaker automatically returns to the initial state and waits for the next operation command. The spare space between the switch-off driving member and the switch-on driving member prevents the switch-off driving member and the switch-on driving member from coming into contact with the handle 5 in the initial state, allowing the switch-off driving member or the switch-on driving member to return to the initial state after operating the handle 5, thereby avoiding the switch-off driving member or the switch-on driving member from malfunctioning and causing damage to the circuit breaker. Specifically, when the switch-on driving member operates on the handle 5 of the circuit breaker to turn on the switch and then return the circuit breaker to its initial state, the switch-off driving member operates on the handle 5 of the circuit breaker to turn off the switch and then return the circuit breaker to its initial state, thereby preventing the switch-on driving member from interfering with the switch-off operation of the switch-off driving member and preventing the switch-off driving member from interfering with the switch-on operation of the switch-on driving member.In one embodiment, a position identification switch is provided on the rolling mechanism, and after the position identification switch is triggered, the control circuit controls the operation of the rolling mechanism to actuate the switching-off drive member or the switching-on drive member to return to the initial position.

[0028] The electrical operating device provided on the front of the circuit breaker handle is suitable for installation inside a cabinet with limited lateral space instead of on the side wall of a conventional circuit breaker, and also avoids the resulting tilting and desynchronization of the circuit breaker contacts while operating the circuit breaker handle 5, or the need to place a separate electrical operating device on each pole of the circuit breaker.

[0029] In one embodiment, the width of the switch-off operating part 31b and the switch-on operating part 31a can be increased as required and actuate the handle 5 of a multi-pole circuit breaker.

[0030] Preferably, as an embodiment, a moving device is also provided in the electric operating device as shown in Fig. 3, and a side wall opposite to the operating surface 11 serves as a connecting surface 12 to which a moving device 6 for displacement is attached. The connecting surface 12 is shown in Fig. 2. The electric operating device is attached to a moving track (not shown) via the moving device 6. The moving device 6 moves the electric operating device along the moving track to correspond to the handles 5 of the various circuit breakers, respectively, and the various circuit breakers are driven to perform a switching-on operation or a switching-off operation.

[0031] 6 and 7, a support plate is provided inside the housing 1 of the circuit breaker's electrical operating device, and the support plate divides the space within the housing 1 into a driving space and a rolling space. The support plate includes a first support plate 103 and a second support plate 104 spaced apart. The space between the first support plate 103 and the second support plate 104 forms the rolling space for mounting the rolling device, and the space between the first support plate 103 and the operating surface 11 forms the driving space for mounting the driving member. Preferably, a slide bar 102 is mounted in the driving space, and the driving member is slidably mounted on the slide bar 102 and moves along the first slide groove 101 on the slide bar 102 under the operation of the rolling mechanism. The first support plate 103 and the second support plate 104 divide the interior space of the housing 1 into two relatively independent sections, providing operating areas for the rolling mechanism and the driving member, and preventing unstable performance due to interference between various functional components.

[0032] Preferably, the rolling mechanism includes a motor 201 and a gear set connected to the motor 201. The gear set includes a switch-on / off output gear, and the switch-on / off output gear has a rolling shaft. The drive member has an interlocking groove that mates with the rolling shaft, and the motor 201 rotates the gear set, and the rolling shaft of the switch-on / off output gear mates with the interlocking groove of the drive member, causing the drive member to slide on the slide bar 102, which operates the handle 5 of the circuit breaker to turn on or off the switch. The gear set is mounted in the rolling space between the first support plate 103 and the second support plate 104.

[0033] Preferably, the speed ratio of the switch-on output gear varies periodically, providing the driving member with a periodically varying driving force and operating speed. The periodically varying speed ratio of the switch-on output gear provides a large driving force to the driving member in the early stage of switch-on and a high switching speed to the driving member in the later stage of switch-on, thereby reducing contact burnout or circuit breaker failure. As a preferred technical measure, the switch-on output gear is an elliptical gear, which allows for setting an appropriate speed ratio and lever ratio, providing the driving member with a periodically varying driving force and operating speed during switch-on and switch-off, thereby avoiding contact burnout or circuit breaker failure. A gear pair composed of non-circular gears is used to achieve a periodically varying speed ratio, has a compact structure, good rigidity, and maintains relatively stable rolling. Of course, the switch-on output gear could also be a non-circular gear, but a periodically varying speed ratio would not be achieved.

[0034] 10 and 11, the switch-on output gear includes a switch-on output gear 205 and a switch-off output gear 206. The rolling shafts of the switch-on output gear include a switch-on rolling shaft 205a provided in the switch-on output gear 205 and a switch-off rolling shaft 206a provided in the switch-off output gear 206. The switch-on rolling shaft 205a is used to operate the switch-on operating part 31a of the driving member so that the handle 5 of the circuit breaker turns on the switch, and the switch-off rolling shaft 206a is used to operate the switch-off operating part 31b of the driving member so that the handle 5 of the circuit breaker turns off the switch. Preferably, the switch-on output gear 205 and the switch-off output gear 206 are meshed with each other and can be driven and controlled simultaneously.

[0035] Preferably, the turn-on output gear 205 and the turn-off output gear 206 are elliptical gears made of metal. The pitch curve of an elliptical gear is an ellipse or a high-order ellipse, and the central angles corresponding to the teeth of the elliptical gears are not always equal. Therefore, the turn-on output gear 205 rotates unevenly while meshing with the turn-off output gear 206. This uneven rotation also exhibits periodic speed changes. In response to this characteristic, an appropriate speed ratio and lever ratio are created to provide a large driving force to the turn-on operation unit 31a in the initial stage of turn-on and a high turn-on speed in the later stage of turn-on. In the initial stage of turn-on, i.e., from the beginning of turn-on to the actual turn-on, the long side of the ellipse of the turn-off output gear 206 contacts the short side of the ellipse of the turn-on output gear 205, thereby providing a large turn-on driving force to the turn-on operation unit 31a. During the latter stage of the switch-on phase, i.e., from the moment of switch-on to the end of the switch-on phase, the short side of the ellipse of the switch-off output gear 206 contacts the long side of the ellipse of the switch-on output gear 205, providing a higher switch-on speed to the switch-on operating part 31a. The center distance between the switch-on output gear 205 and the switch-off output gear 206 is fixed as they rotate, maintaining good meshing. The rotation force and lever work in conjunction with the circuit breaker's operating process to speed up the switch-on operation, increasing the initial switch-on force at the moment the moving contacts come into contact with the stationary contacts. The switch-on output gear 205 and the switch-off output gear 206 achieve a periodically varying speed ratio using a gear pair composed of non-circular gears, providing a compact structure, good rigidity, relatively stable rolling, and a prolonged service life due to the metal material. Obviously, both the switch-on output gear 205 and the switch-off output gear 206 could be circular gears, but they would not achieve a periodically varying speed ratio.

[0036] Specifically, the gear set includes a first-stage gear 202, a second-stage gear 203, and a third-stage gear 204. The motor 201 meshes with the first-stage gear 202 via a worm, the first-stage gear 202 meshes with the second-stage gear 203, the second-stage gear 203 meshes with the third-stage gear 204, and a switch-on output gear is attached to the third-stage gear 204. As shown in Figures 8, 10, and 11, the third-stage gear 204 includes a switch-on output gear 205 and a switch-off output gear 206 that mesh with each other. The switch-on output gear 205 and the third-stage gear 204 are driven by the same rotation axis, and the rotation axis of the switch-on output gear 205 is arranged eccentrically, that is, the rotation axis of the switch-on output gear 205 is not located at the center of the switch-on output gear 205. The switch-off output gear 206 meshes with the switch-on output gear 205, and the rotation axis of the switch-off output gear 206 is arranged eccentrically, that is, the rotation axis of the switch-off output gear 206 is not provided at the center of the switch-off output gear 206. A switch-on rolling axis 205a is provided in the switch-on output gear 205, and a switch-off rolling axis 206a is provided in the switch-off output gear 206, and the eccentric arrangement keeps the rotation centers of the two elliptical gears at a fixed distance. Of course, the third gear 204 and the switch-off output gear 206 may also be driven by the same rotation axis, and the switch-off output gear 206 rotates the switch-on output gear 205.

[0037] As shown in Figures 21 and 22, the transfer mechanism further includes a control gear 207 and a plurality of position identification switches. The control gear 207 is provided with a raised trigger protrusion 207a. The plurality of position identification switches are fixed inside the housing 1 and are spaced apart on a circumference coaxial with the control gear 207, with their preferred positions being close to one side of the second support plate 104 (see Figures 6 and 7 for the second support plate 104). The plurality of position identification switches cooperate with the trigger protrusion 207a to provide position signals to control the motor to rotate forward, reverse, or stop. The plurality of position identification switches include an initial position identification switch 208a, a switch-on position identification switch 208b, and a switch-off position identification switch 208c. The control gear 207 and the switch-off output gear 206 are mounted on the same rotation axis, and the rotation of the switch-off output gear 206 drives and rotates the control gear 207. The motor 201 sequentially drives and rotates a switch-on output gear 205, a switch-off output gear 206, and a control gear 207.

[0038] During the on-state, the motor 201 rotates the on-state output gear 205 in the on-state direction under the rolling of the first-stage gear 202, the second-stage gear 203, and the third-stage gear 204. Taking the counterclockwise rotation of the on-state output gear as an example (see the direction in FIG. 22), the off-state output gear 206, the control gear 207, and the trigger protrusion 207a all rotate clockwise at this time (see the direction in FIG. 21 as counterclockwise rotation). The trigger protrusion 207a rotates from the initial position identification switch 208a to the on-state position identification switch 208b, and the on-state output gear 205 operates the handle 5 of the circuit breaker via the on-state rolling shaft 205a to the on-state operating part 31a of the on-state driving member to turn on the circuit breaker. When the trigger protrusion 207a triggers the on-state position identification switch 208b, the motor 201 is controlled to rotate in the reverse direction in the off-state direction. When the trigger protrusion 207a triggers the initial position identification switch 208a, the switch-on operation unit 31a is controlled to return to the initial position, causing the motor 201 to stop rotating.

[0039] While the switch is turned off, the motor 201 rotates the switch-off output gear 205 in the switch-off direction under the rolling of the first-stage gear 202, the second-stage gear 203, and the third-stage gear 204. Taking the clockwise rotation of the switch-on output gear 205 as an example (see the direction in FIG. 22), the switch-off output gear 206, the control gear 207, and the trigger protrusion 207a all rotate counterclockwise at this time (see the direction in FIG. 21 as clockwise rotation). The trigger protrusion 207a rotates from the initial position identification switch 208a to the switch-off position identification switch 208c, and the switch-off output gear 206 rotates in the switch-off direction, which activates the switch-off operating unit 31b via the switch-off rolling shaft 206a to operate the handle 5 of the circuit breaker, turning off the switch. When the trigger protrusion 207a triggers the switch-on / off position identification switch 208c, the motor 201 is controlled to rotate in the reverse direction and rotates in the switch-on direction. When the trigger protrusion 207a triggers the initial position identification switch 208a, the switch-off operation unit 31b is controlled to return to the initial position.

The switch-on drive member and the switch-off drive member are provided with a switch-on operation unit 31a and a switch-off operation unit 31b, respectively. The switch-on drive member and the switch-off drive member are provided with interlocking grooves, each with openings facing in opposite directions, which periodically engage or disengage the rolling shaft of the rolling mechanism. Preferably, the drive member includes an interlocking member connected to the rolling mechanism, and the interlocking groove is provided on the interlocking member and used to connect to the rolling shaft.

[0042] The interlocking groove of the driving member converts the circular motion of the switch-on output gear into linear motion, and the driving member performs linear motion within the first slide groove 101 in accordance with the cooperation of the interlocking groove and the rolling shaft. The switch-on operation part 31a and the switch-off operation part 31b of the driving member respectively operate the circuit breaker handle 5 to turn the switch on or off. Preferably, the driving member performs linear motion along the slide bar 102. Specifically, as shown in FIG. 8 , the interlocking groove of the switch-on driving member is the first interlocking groove 30a, and the interlocking groove of the switch-off driving member is the second interlocking groove 30c. When the rolling shaft is aligned with the first interlocking groove 30a of the switch-on driving member, the rolling shaft is spaced from the second interlocking groove 30c of the switch-off driving member to prevent malfunction of the switch-off driving member. When the rolling shaft is aligned with the second interlocking groove 30c of the switch-off driving member, the rolling shaft is spaced from the first interlocking groove 30a of the switch-on driving member to prevent malfunction of the switch-off driving member.

Similarly, the closed end of the second interlocking groove 30c cooperates with the off-switch rolling shaft 206a to move the second interlocking member, and the open end of the second interlocking groove 30c rolls out after the off-switch rolling shaft 206a is released from the second interlocking member to prevent the off-switch operating unit 31b from malfunctioning while the switch is turned on.

[0044] Specifically, as shown in Figures 7 and 8, the driving member includes an interlocking member and an actuating member driven by the interlocking member. The rolling mechanism is connected to the interlocking member, which is attached to the slide bar 102. The actuating member is interlocked with the interlocking member. The interlocking groove is provided on the interlocking member and used to connect with the rolling shaft. The switch-on operation unit 31a and the switch-off operation unit 31b are provided on the actuating member. The interlocking member specifically includes a first interlocking member and a second interlocking member. The first interlocking member has a first interlocking groove 30a that periodically cooperates with the switch-on rolling shaft 205a, and the second interlocking member has a second interlocking groove 30b that periodically cooperates with the switch-off rolling shaft 206a. The actuating member includes a switch-on member with a switch-on operation unit 31a and a switch-off member with a switch-off operation unit 31b. Preferably, an elastic buffer member 4 is provided between the interlocking member and the actuating member. The elastic buffer member is used to absorb the residual amount of switching on / off, and prevents the switch-on operation part 31a and the switch-off operation part 31b from hitting the handle 5, causing the handle 5 to be pushed to the intended position and thus breaking. Of course, the elastic buffer member 4 may not be provided at all, or may be provided only on the switch-on drive member and not on the switch-off drive member.

[0045] Specifically, as shown in Figures 12 and 14, the driving member includes a switch-on driving member having a switch-on operation portion 31a and a switch-off driving member having a switch-off operation portion 31b. The switch-on driving member and the switch-off driving member are operating components driven by the interlocking member. Specifically, the switch-on driving member includes a first interlocking member and a switch-on member, the first interlocking member is attached to the slide bar 102, and the switch-on member is attached to the slide bar 102 and interlocks with the first interlocking member.

As shown in FIG. 6 , a compression spring 7 is provided between the turn-on drive member and the turn-off drive member. The compression spring 7 assists in the return of the turn-on drive member and the turn-off drive member, and also reduces the effect of a gap when the turn-on drive member and the turn-off drive member cooperate. The linear movement of the turn-on drive member deforms the compression spring 7 during the turn-on period, storing energy. After the turn-on period is completed, the elastic force of the compression spring 7 provides an auxiliary driving force for the turn-on drive member to return to its initial position. Similarly, the linear movement of the turn-off drive member deforms the compression spring 7 during the turn-off period, storing energy, and the elastic force of the compression spring 7 provides an auxiliary driving force for the turn-off drive member to return to its initial position. Preferably, the compression spring 7 is wound around the slide bar 102 between the switch-on drive member and the switch-off drive member, and may be used as the compression spring 7 or may provide a driving force for the first linkage member and the second linkage member to return to their original position in order to ensure their return speed.

The switch-off member sequentially connects the third side wall 313, the second connecting wall 316, and the fourth side wall 314 to form a U-shaped structure. A through-hole for the slide bar 102 to pass through is provided in the opposing third side wall 313 and fourth side wall 314. A switch-off operating unit 31b for operating the circuit breaker handle 5 to turn off the switch is provided in the third side wall 313 or the fourth side wall 314.
