Description

Technical Field

[0001] This application belongs to the field of electrical equipment technology, and in particular relates to a multi-functional integrated device and circuit breaker. Background Technology

[0002] With the continuous development of power systems, the demand for circuit breakers is increasing, especially in high-voltage AC / DC applications. Current circuit breakers typically employ a split accessory structure, where components such as shunt trip units, auxiliary contacts, and alarm contacts all require independent installation. However, these independently installed accessory structures usually occupy a significant amount of space within the circuit breaker, resulting in an excessively large overall size and increased installation and maintenance costs. Utility Model Content

[0003] This application provides a multifunctional integrated device and circuit breaker that can achieve a miniaturized design of the circuit breaker as a whole and reduce installation and maintenance costs.

[0004] This application provides a multifunctional integrated device, comprising: a support frame including a first side and a second side disposed opposite to each other along a first direction; an auxiliary signal unit disposed on the first side of the support frame, including a first linkage component and an auxiliary signal element disposed sequentially along a second direction, wherein at least a portion of the first linkage component is movably disposed along the second direction to contact or disconnect from the auxiliary signal element; a shunt trip unit disposed on the first side of the support frame and spaced apart from the auxiliary signal unit in a third direction, the shunt trip unit including an electromagnetic drive component and a trip rod, the electromagnetic drive component being capable of driving the trip rod to move along the second direction to achieve active tripping operation; and an alarm signal unit disposed on the second side of the support frame, the alarm signal unit including a second linkage component and an alarm signal element, the second linkage component being movably disposed along a direction toward or away from the alarm signal element to contact the alarm signal element to trigger a tripping alarm signal, or to disconnect to achieve a re-tripping operation.

[0005] In the above-mentioned multifunctional integrated device, the first linkage component includes a rotatable transmission mechanism and a first trigger element movable in a second direction. The transmission mechanism and the auxiliary signal element are spaced apart in the second direction. The first trigger element is located between the transmission mechanism and the auxiliary signal element and is movably connected to the transmission mechanism. The transmission mechanism is used to abut against the contact structure of the circuit breaker to rotate.

[0006] In the above-mentioned multifunctional integrated device, the transmission mechanism includes a first transmission component and a first reset component. The first transmission component includes a first transmission part, a second transmission part, and a sleeve connection part. The sleeve connection part is a cylindrical structure sleeved on the first reset component. The first reset component has elastic force along its circumference. The first transmission part and the second transmission part are circumferentially connected to the outer circumferential surface of the sleeve connection part. The first transmission part is used to abut against the contact structure, and the second transmission part is rotatably connected to the first trigger component.

[0007] In the above-mentioned multifunctional integrated device, the auxiliary signal unit includes two auxiliary signal elements spaced apart along a third direction, and a guide channel extending along a second direction is formed between the two auxiliary signal elements. The first trigger element is movably installed in the guide channel along the second direction.

[0008] In the above-mentioned multifunctional integrated device, the electromagnetic drive component includes an electromagnetic control component, a second transmission component, and a second reset component. The electromagnetic control component and the tripping rod are spaced apart along the second direction. The second transmission component and the second reset component are both located between the electromagnetic control component and the tripping rod. The second transmission component is movably connected to the tripping rod. The electromagnetic control component drives the second transmission component to move through a magnetic field and causes the tripping rod to move along the second direction. The second reset component has an elastic force and abuts against the end face of the tripping rod perpendicular to the second direction.

[0009] The multifunctional integrated device described above includes a trip lever comprising a lever body, a trip connection portion, a third transmission portion, and a reset protrusion portion. The lever body extends along a second direction. The third transmission portion is located at one end of the lever body near the second transmission member and is movably connected to the second transmission member. The trip connection portion is located at the other end of the lever body and extends along a third direction. The reset protrusion portion protrudes from the middle of the lever body in a third direction and is used to abut against and cooperate with the second reset member.

[0010] In the above-mentioned multifunctional integrated device, the second linkage component includes an alarm drive component, a fourth transmission component, and a third reset component. The alarm drive component is used to cooperate with the locking structure of the circuit breaker. The alarm drive component and the alarm signal component are spaced apart in the second direction. The fourth transmission component is movably disposed between the alarm drive component and the alarm signal component and cooperates with the alarm drive component. The third reset component is connected to the side of the fourth transmission component away from the alarm signal component to provide a reset force to the fourth transmission component.

[0011] The multifunctional integrated device described above includes an alarm drive unit comprising a rotating shaft and a drive unit protruding from the outer circumference of the rotating shaft. The alarm drive unit is rotatably mounted on a support frame with the rotating shaft as its center. The fourth transmission unit comprises a fourth transmission unit and a fifth transmission unit connected at a bending angle and rotatably mounted on the support frame with the connection point of the two as the rotating shaft. The fourth transmission unit is positioned opposite to the drive unit. One side of the fifth transmission unit is positioned opposite to the alarm signal unit, and the other side is connected to the third reset unit.

[0012] On the other hand, this application embodiment also provides a circuit breaker, which includes the above-mentioned multifunctional integrated device. The circuit breaker further includes: a contact structure, the contact structure including a moving contact and a stationary contact, the moving contact being rotatably disposed to contact or separate from the stationary contact, the moving contact including a protruding trigger portion, the trigger portion being disposed opposite to and abutting against the first linkage component.

[0013] The circuit breaker described above also includes a traction rod, a locking structure, and a tripping structure. The traction rod extends along a first direction, and its first end is connected to the tripping rod of the shunt tripping unit. The second end of the traction rod is connected to the second linkage component of the alarm signal unit through the locking structure. The locking structure is detachably connected to the tripping structure to realize the tripping and re-tripping of the circuit breaker.

[0014] The multifunctional integrated device of this application embodiment includes a support frame, an auxiliary signal unit, a shunt trip unit, and an alarm signal unit. The auxiliary signal unit and the shunt trip unit are installed on a first side of the support frame in a first direction, and are spaced apart in a third direction. The alarm signal unit is installed on a second side of the support frame in the first direction. Therefore, the auxiliary signal unit, the shunt trip unit, and the alarm signal unit can be integrated into the support frame and are all independently set to realize the functions of auxiliary signal output, shunt trip, and alarm signal output, respectively.

[0015] At least a portion of the first linkage component of the auxiliary signal unit is movably disposed along a second direction to contact or disconnect from the auxiliary signal element, thereby outputting an auxiliary signal. The electromagnetic drive component of the shunt trip unit can drive the trip lever to move along the second direction to achieve an active trip operation. The second linkage component of the alarm signal unit is movably disposed in a direction toward or away from the alarm signal element to contact the alarm signal element to trigger a trip alarm signal, or to disconnect to achieve a re-trip operation.

[0016] When the auxiliary signal unit and the shunt trip unit located on the same side perform driving actions, since at least part of the first linkage component and the trip lever both move along the second direction, their actions will not interfere with each other. Furthermore, the second linkage component of the alarm signal unit located on the other side performs independent actions and will not interfere with the movement of the first linkage component and the trip lever, thus realizing a multi-functional, independent, and integrated setup.

[0017] Therefore, the multi-functional integrated device in this application embodiment achieves the integrated setting of multiple functions while ensuring the independence of multiple functions, making the overall size of the multi-functional integrated device smaller, thereby realizing the miniaturization design of the circuit breaker as a whole and reducing installation and maintenance costs.

[0036] The features and exemplary embodiments of various aspects of this application will be described in detail below. To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain this application and not to limit it. For those skilled in the art, this application can be implemented without some of these specific details. The following description of the embodiments is merely to provide a better understanding of this application by illustrating examples.

[0037] like Figures 1 to 8 As shown, this application embodiment provides a multifunctional integrated device, comprising: a support frame 1, including a first side and a second side disposed opposite to each other along a first direction X; an auxiliary signal unit 2, disposed on the first side of the support frame 1, including a first linkage component 21 and an auxiliary signal component 22 disposed sequentially along a second direction Y, wherein at least a portion of the first linkage component 21 is movably disposed along the second direction Y to contact or disconnect from the auxiliary signal component 22; a shunt trip unit 3, disposed on the first side of the support frame 1 and spaced apart from the auxiliary signal unit 2 along a third direction Z, the shunt trip unit 3 including an electromagnetic drive component 31 and a trip rod 32, the electromagnetic drive component 31 being able to drive the trip rod 32 to move along the second direction Y to achieve active tripping operation; and an alarm signal unit 4, disposed on the second side of the support frame 1, the alarm signal unit 4 including a second linkage component 41 and an alarm signal component 42, the second linkage component 41 being movably disposed along a direction toward or away from the alarm signal component 42 to contact the alarm signal component 42 to trigger a tripping alarm signal, or disconnect to achieve a re-tripping operation.

[0038] In specific implementation, the multifunctional integrated device of this application embodiment includes a support frame 1, an auxiliary signal unit 2, a shunt trip unit 3, and an alarm signal unit 4. The auxiliary signal unit 2 and the shunt trip unit 3 are installed on the first side of the support frame 1 in the first direction X, and the two are spaced apart in the third direction Z. The alarm signal unit 4 is installed on the second side of the support frame 1 in the first direction X. Therefore, the auxiliary signal unit 2, the shunt trip unit 3, and the alarm signal unit 4 can be integrated into the support frame 1 and all three are set independently to realize the functions of auxiliary signal output, shunt trip and alarm signal output, respectively.

[0039] At least a portion of the first linkage component 21 of the auxiliary signal unit 2 is movable along the second direction Y to contact or disconnect from the auxiliary signal component 22. When the first linkage component 21 contacts the auxiliary signal component 22, the auxiliary signal component 22 is energized and outputs a trip position signal. When the first linkage component 21 disconnects from the auxiliary signal component 22, the auxiliary signal component 22 is de-energized and reset to output a closing position signal, thereby realizing the output of tripping and closing auxiliary signals.

[0040] The electromagnetic drive assembly 31 of the shunt trip unit 3 can drive the trip rod 32 to move along the second direction Y. When the electromagnetic drive assembly 31 is energized, the trip rod 32 moves towards the direction close to the electromagnetic drive assembly 31, and the trip rod 32 sequentially drives the traction rod 6 and the locking structure 7 to perform an active tripping operation, thereby releasing the latch between the locking structure 7 and the tripping structure. When the electromagnetic drive assembly 31 is de-energized, the trip rod 32 moves away from the electromagnetic drive assembly 31, causing the trip rod 32 to separate from the traction rod 6, and the circuit breaker remains in the tripped state. Therefore, the shunt trip unit 3 can shunt trip the circuit breaker when it is closed, so as to cut off the circuit breaker circuit in an emergency.

[0041] The second linkage component 41 of the alarm signal unit 4 is movably arranged in a direction toward or away from the alarm signal element 42. When a passive trip occurs between the locking structure 7 and the tripping structure, the second linkage component 41 moves toward the alarm signal element 42 and comes into contact with it, causing the alarm signal element 42 to output a tripping alarm signal. When a re-clamping operation is required between the locking structure 7 and the tripping structure, the second linkage component 41 needs to be controlled to move away from the alarm signal element 42, so that the locking structure 7 and the tripping structure are re-clamped. At this time, the second linkage component 41 also separates from the alarm signal element 42, and the alarm signal element 42 outputs a re-clamping reset signal, allowing the circuit breaker to resume normal opening and closing operations.

[0042] When the auxiliary signal unit 2 and the shunt trip unit 3, which are located on the same side, are driven, their actions will not interfere with each other because at least part of the first linkage component 21 and the trip lever 32 both move along the second direction Y. Furthermore, the second linkage component 41 of the alarm signal unit 4, which is located on the other side, will operate independently and will not interfere with the movement of the first linkage component 21 and the trip lever 32. This achieves a multi-functional, independent, and integrated setup.

[0043] Therefore, the multi-functional integrated device in this application embodiment achieves the integrated setting of multiple functions while ensuring the independence of multiple functions, making the overall size of the multi-functional integrated device smaller, thereby realizing the miniaturization design of the circuit breaker as a whole and reducing installation and maintenance costs.

[0044] like Figure 1 and Figure 3 As shown in the embodiment of this application, the multifunctional integrated device includes a first linkage component 21 comprising a rotatable transmission mechanism 211 and a first trigger 212 movable along the second direction Y. The transmission mechanism 211 and the auxiliary signal component 22 are spaced apart in the second direction Y. The first trigger 212 is disposed between the transmission mechanism 211 and the auxiliary signal component 22 and is movably connected to the transmission mechanism 211. The transmission mechanism 211 is used to abut against and cooperate with the contact structure 5 of the circuit breaker to rotate.

[0045] In specific implementation, the transmission mechanism 211 abuts against the contact structure 5 of the circuit breaker. The rotation of the contact structure 5 can drive the transmission mechanism 211 to rotate. Since the first trigger 212 is movably connected to the transmission mechanism 211, the rotation of the transmission mechanism 211 can be converted into the linear movement of the first trigger 212 along the second direction Y, so that the first trigger 212 can reach the position of the auxiliary signal element 22 along the second direction Y, so as to contact the auxiliary signal element 22 and realize the output of the auxiliary signal.

[0046] Therefore, the transmission mechanism 211 and the first trigger 212 decompose the large-amplitude rotation of the contact structure 5 into small-amplitude rotation and translational movement along the second direction Y, so that the overall moving area of ​​the first linkage component 21 within the support frame 1 is small, thereby reducing the overall layout space and realizing the miniaturization design of the multifunctional integrated device.

[0047] In the multifunctional integrated device of this application embodiment, the auxiliary signal unit 2 includes two auxiliary signal elements 22 spaced apart along the third direction Z, and a guide channel 221 extending along the second direction Y is formed between the two auxiliary signal elements 22. The first trigger element 212 is movably installed in the guide channel 221 along the second direction Y.

[0048] In specific implementation, the guide channel 221 extending along the second direction Y plays a guiding role in the movement of the first trigger 212, so that when the first trigger 212 moves, it can be blocked by the auxiliary signal elements 22 on both sides in the third direction Z, so that the first trigger 212 can accurately reach the contact position of the auxiliary signal element 22, thereby achieving stable auxiliary signal output.

[0049] Specifically, in the two auxiliary signal elements 22, each auxiliary signal element 22 has a contact point on its surface facing the other auxiliary signal element 22, so that the first trigger element 212 can make contact with the contact point when it passes through the guide channel 221.

[0050] Specifically, the first trigger 212 is arranged in a rod-shaped structure. One end of the first trigger 212 is rotatably connected to the transmission mechanism 211, and the other end is inclined on both sides in the third direction Z, so as to facilitate the pressing of the contact and avoid damage to the contact structure.

[0051] like Figure 1 and Figure 3 As shown in the embodiment of this application, the multifunctional integrated device includes a transmission mechanism 211 comprising a first transmission member 2111 and a first reset member 2112. The first transmission member 2111 includes a first transmission part 21111, a second transmission part 21112, and a sleeved connecting part 21113. The sleeved connecting part 21113 is a cylindrical structure sleeved on the first reset member 2112. The first reset member 2112 has an elastic force along its circumference. The first transmission part 21111 and the second transmission part 21112 are circumferentially spaced and connected to the outer circumferential surface of the sleeved connecting part 21113. The first transmission part 21111 is used to abut against the contact structure 5, and the second transmission part 21112 is rotatably connected to the first trigger member 212.

[0052] In specific implementation, such as Figure 5 As shown, when the contact structure 5 rotates to open, it can abut against the first transmission part 21111, thereby driving the first transmission member 2111 to rotate around the sleeve connection part 21113 of the cylindrical structure. During the rotation of the sleeve connection part 21113, the second transmission part 21112, which is circumferentially spaced from the first transmission member 2111, can move circumferentially, thereby driving the first trigger member 212 to move along the second direction Y and make contact with the contact. The auxiliary signal member 22 outputs the opening signal.

[0053] like Figure 4As shown, when the contact structure 5 rotates during closing, it separates from the first transmission part 21111. The first transmission part 21111 loses its resisting force. Since the first reset member 2112 has elastic force along its circumference, it can cause the sleeve connection part 21113 to rotate and reset, thereby causing the second transmission part 21112 to drive the first trigger member 212 to retract along the second direction Y. The first trigger member 212 releases its contact with the contact, and the auxiliary signal member 22 outputs a closing signal.

[0054] Therefore, the first transmission component 2111 and the first reset component 2112 of the transmission mechanism 211 achieve the output of opening and closing signals through abutting cooperation and elastic reset, without the need for a more complex structure, simplifying the overall structure of the multi-functional integrated device and further realizing the miniaturization design of the circuit breaker.

[0055] Specifically, the first reset element 2112 is a reaction torsion spring.

[0056] like Figure 1 and Figure 3 As shown in the embodiment of this application, the multifunctional integrated device includes an electromagnetic drive assembly 31 comprising an electromagnetic control component 311, a second transmission component 312, and a second reset component 313. The electromagnetic control component 311 and the tripping lever 32 are spaced apart along the second direction Y. The second transmission component 312 and the second reset component 313 are both disposed between the electromagnetic control component 311 and the tripping lever 32. The second transmission component 312 is movably connected to the tripping lever 32. The electromagnetic control component 311 drives the second transmission component 312 to move through a magnetic field, thereby moving the tripping lever 32 along the second direction Y. The second reset component 313 has an elastic force and abuts against the end face of the tripping lever 32 perpendicular to the second direction Y.

[0057] In practical implementation, when an active tripping operation is required in an emergency, a control voltage is applied to the electromagnetic control component 311 to generate an electromagnetic field, thereby driving the second transmission component 312 to move along the second direction Y. This causes the tripping lever 32 to drive the traction rod 6, achieving the tripping between the locking structure 7 and the tripping structure. When an active tripping operation is not required, the electromagnetic control component 311 is kept de-energized to prevent the tripping lever 32 from pulling the traction rod 6 and causing a tripping situation.

[0058] Therefore, the electromagnetic control component 311 of the electromagnetic drive assembly 31 can be controlled by switching the power on and off, thereby enabling active tripping operation in a remote state, which facilitates timely and convenient control in emergency situations.

[0059] Specifically, the second transmission member 312 is rotatably configured. Under the electromagnetic drive of the electromagnetic control member 311, one end of the second transmission member 312 connected to the trip rod 32 can rotate around the fixed shaft connected to the other end. Since the second transmission member 312 is movably connected to the trip rod 32, the rotational action can be converted into a linear action of the trip rod 32 along the second direction Y, thereby avoiding interference between the trip rod 32 and the first linkage component 21, and not affecting the realization of the functions of the auxiliary signal unit 2 and the shunt trip unit 3.

[0060] The multifunctional integrated device of this application embodiment includes a tripping lever 32 comprising a lever body 321, a tripping connection portion 322, a third transmission portion 323, and a reset protrusion 324. The lever body 321 extends along the second direction Y. The third transmission portion 323 is disposed at one end of the lever body 321 near the second transmission member 312 and is movably connected to the second transmission member 312. The tripping connection portion 322 is disposed at the other end of the lever body 321 and extends along the third direction Z. The reset protrusion 324 protrudes from the middle of the lever body 321 in the third direction Z and is used to abut against the second reset member 313.

[0061] In specific implementation, the third transmission part 323 is located at one end of the rod body 321 near the second transmission member 312, so as to facilitate its movable connection with the second transmission member 312, thereby realizing the conversion of rotational action to linear action. The release connection part 322 located at the other end of the rod body 321 extends in the third direction Z to form a hook-shaped structure, which facilitates the engagement and connection between the release connection part 322 and the traction rod 6, thereby driving the traction rod 6 to move for active release operation.

[0062] The reset protrusion 324 protrudes from the middle of the rod body 321 in the third direction Z, allowing the second reset member 313 to abut against the end face of the reset protrusion 324 perpendicular to the second direction Y, thereby realizing the reset operation of the trip lever 32. Therefore, the abutment position of the second reset member 313 against the trip lever 32 and the mating position of the second transmission member 312 with the trip lever 32 are spaced apart in the third direction Z, and their movements will not interfere with each other, ensuring the stability of the tripping and reset operations.

[0063] Specifically, the tripping connection 322 and the third transmission part 323 are arranged to protrude to the same side in the third direction Z, while the reset protrusion 324 is arranged to protrude to the other side in the third direction Z, thereby avoiding the impact of the reset action on the transmission action and the tripping action.

[0064] Specifically, the third transmission part 323 has a through hole extending in the third direction Z, and the second transmission member 312 is rotatably disposed in the through hole and movable in the third direction Z, so as to convert the rotational motion into linear motion.

[0065] Specifically, the support frame 1 has a through hole on the wall portion perpendicular to the second direction Y. The release rod 32 can slide in the through hole along the second direction Y. The through hole provides a limiting effect for the release rod 32, so that the release rod 32 can only slide along the second direction Y, thereby achieving a stable release effect.

[0066] like Figure 2 and Figure 8 As shown in the embodiment of this application, the multifunctional integrated device includes a second linkage component 41 comprising an alarm drive component 411, a fourth transmission component 412, and a third reset component 413. The alarm drive component 411 is used to cooperate with the locking structure 7 of the circuit breaker. The alarm drive component 411 and the alarm signal component 42 are spaced apart in the second direction Y. The fourth transmission component 412 is movably disposed between the alarm drive component 411 and the alarm signal component 42 and is movably cooperated with the alarm drive component 411. The third reset component 413 is connected to the side of the fourth transmission component 412 away from the alarm signal component 42 to provide a reset force to the fourth transmission component 412.

[0067] In practical implementation, the alarm drive component 411 can drive the fourth transmission component 412 to move between the alarm drive component 411 and the alarm signal component 42. The third reset component 413 is connected to the side of the fourth transmission component 412 away from the alarm signal component 42 to facilitate reset driving. The third reset component 413 is positioned in the third direction Z, spaced apart from both the alarm drive component 411 and the alarm signal component 42. Therefore, when it undergoes elastic deformation, it will not interfere with the driving action of the alarm drive component 411, thereby realizing independent driving and reset operations. This allows the fourth transmission component 412 to contact the alarm signal component 42 to trigger a trip alarm signal, or to disconnect and realize a re-trigger operation.

[0068] like Figure 2 and Figure 8 As shown in the embodiment of this application, the multifunctional integrated device includes an alarm drive member 411 comprising a rotating shaft portion 4111 and a drive portion 4112 protruding from the outer peripheral surface of the rotating shaft portion 4111. The alarm drive member 411 is rotatably mounted on the support frame 1 with the rotating shaft portion 4111 as the center. The fourth transmission member 412 comprises a fourth transmission portion 4121 and a fifth transmission portion 4122 connected at a bending angle and rotatably mounted on the support frame 1 with the connection point of the two as the rotating shaft. The fourth transmission member 412 and the drive portion 4112 are positioned opposite each other. One side of the fifth transmission portion 4122 is positioned opposite to the alarm signal member 42, and the other side is connected to the third reset member 413.

[0069] In specific implementation, such as Figure 6 and Figure 7As shown, during the re-clamping operation, the rotating shaft 4111 and the driving part 4112 rotate together. The driving part 4112 can abut against the outside of the fourth transmission part 4121 of the fourth transmission member 412, thereby driving the fourth transmission part 4121 and the fifth transmission part 4122 to rotate around their connection point. This allows the fifth transmission part 4122 to move away from the alarm signal member 42, thereby canceling the alarm signal and simultaneously compressing the third reset member 413. After the re-clamping, the locking structure 7 and the release structure are in the locked state, and the overall position of the alarm driving member 411 remains unchanged, thus preventing the alarm signal from being triggered.

[0070] like Figure 2 and Figure 8 As shown, when the locking structure 7 and the release structure are passively released, they lose the holding force on the alarm drive component 411 as a whole. The third reset component 413 performs elastic reset, thereby pushing the fifth transmission part 4122 to move in the direction toward the alarm signal component 42 and come into contact with the contact of the alarm signal component 42, triggering the alarm signal.

[0071] Therefore, through the transmission cooperation of the alarm drive component 411, the fourth transmission component 412 and the third reset component 413, the alarm signal can be automatically triggered in the tripped state, so as to perform the re-tripping operation in a timely manner, ensure the normal operation of the circuit breaker, and thus ensure the normal production rhythm.

[0072] like Figures 1 to 8 As shown, this application embodiment also provides a circuit breaker, which includes the above-mentioned multi-functional integrated device. The circuit breaker further includes: a contact structure 5, which includes a moving contact 51 and a stationary contact 52. The moving contact 51 is rotatably disposed to contact or separate from the stationary contact 52. The moving contact 51 includes a protruding trigger part 511, which is positioned opposite to and abuts against the first linkage component 21.

[0073] In specific implementation, the contact structure 5 of the circuit breaker is arranged opposite to the auxiliary signal unit 2 of the multi-functional integrated device. The moving contact 51 and the stationary contact 52 of the contact structure 5 are separately and jointly arranged. By rotating the moving contact 51, it can come into contact with or separate from the stationary contact 52 to realize the opening and closing of the circuit breaker. The protruding trigger part 511 of the moving contact 51 can rotate to abut against the first transmission part 21111 of the first linkage assembly 21 during the rotation of the moving contact 51 as a whole, thereby causing the first transmission member 2111 to rotate, and then causing the first trigger member 212 to translate along the second direction Y to realize the output of the auxiliary signal.

[0074] The circuit breaker of this application embodiment further includes a traction rod 6, a locking structure 7, and a tripping structure. The traction rod 6 extends along a first direction X. The first end of the traction rod 6 is connected to the tripping rod 32 of the shunt tripping unit 3. The second end of the traction rod 6 is connected to the second linkage component 41 of the alarm signal unit 4 through the locking structure 7. The locking structure 7 is detachably connected to the tripping structure to realize the tripping and re-tripping of the circuit breaker.

[0075] In practical implementation, the traction rod 6 extends along the first direction X, covering both the first and second sides of the support frame 1. Its two ends can respectively connect to the shunt trip unit 3 and the alarm signal unit 4, thereby enabling the shunt trip unit 3 to actively trip on the first side, and the alarm signal unit 4 to re-trigger on the second side, as well as outputting an alarm signal after passive tripping, thus improving the overall operational coordination of the circuit breaker. Therefore, by setting the traction rod 6, the shunt trip unit 3 and the alarm signal unit 4 in the circuit breaker can be integrated into a multi-functional integrated device, achieving a miniaturized circuit breaker design.

[0076] Furthermore, only the alarm signal unit 4 is provided on the second side of the support frame 1. The locking structure 7 and the tripping structure are located on the second side of the support frame 1, which can improve the space utilization rate inside the circuit breaker and further realize the miniaturization of the circuit breaker.

[0078] The above description is merely a specific implementation of this application. Those skilled in the art will clearly understand that, for the sake of convenience and brevity, the specific working processes of the systems, modules, and units described above can be referred to the corresponding processes in the foregoing method embodiments, and will not be repeated here.
