Description
Technical Field
[0001] This utility model relates to the field of circuit breaker switch technology, and in particular to a circuit breaker switch. Background Technology
[0002] When an overload or short circuit fault occurs in the circuit, causing excessive current, the electromagnetic trip unit and thermal trip unit inside the circuit breaker will activate. When a large current is short-circuited, the electromagnetic trip unit uses electromagnetic force to activate the trip mechanism and instantly cut off the circuit. When an overload occurs, the thermal trip unit uses the heat generated by the current to heat and bend the bimetallic strip, which pushes the trip mechanism to activate and cut off the circuit.
[0003] A search revealed Chinese patent publication number CN209087694U, which discloses a circuit breaker switch, including a support frame, a vacuum interrupter, and a disconnector transmission assembly and a circuit breaker mechanism respectively disposed at both ends of the vacuum interrupter. The support frame is equipped with an isolation spindle and a circuit breaker spindle, which are connected to the disconnector transmission assembly and the circuit breaker mechanism, respectively. The circuit breaker mechanism has a flexible connection for connecting to a busbar. This utility model achieves isolation, connection, and grounding actions through the isolation mechanism. The connection between the vacuum interrupter and the circuit breaker mechanism allows for the closing or opening of the interrupter. While the utility model has a simple structure and small size, in actual use, the single-spring circuit breaker has poor structural stability and may lead to misoperation. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a circuit breaker switch, which aims to improve the existing technology where the device uses a single spring circuit breaker, resulting in poor structural stability and potential for misoperation.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a circuit breaker switch, comprising a frame one, a frame two fixedly connected to the top of the frame one, a plurality of solid-sealed poles fixedly connected at equal intervals to the front side of the frame two, an isolating blade rotatably connected to the front end of each of the plurality of solid-sealed poles, a rotating rod rotatably connected to the front side of the frame one, a plurality of pull rods one rotatably connected at equal intervals to the front side of the rotating rod, the front end of each of the plurality of pull rods one rotatably connected to the bottom of the isolating blade, a vacuum interrupter chamber slidably connected inside each of the plurality of solid-sealed poles, a movable conductive rod fixedly connected to the rear end of each of the plurality of vacuum interrupter chambers, and a movable conductive rod... The rear ends of all are through solid-sealed poles. Corrugated pipes are slidably connected to the outer walls of the multiple moving conductive rods. Connecting rods are fixedly connected to the rear ends of the multiple moving conductive rods. Overtravel springs are slidably connected to the outer walls of the multiple connecting rods. Conductive copper flexible connectors are fixedly connected to the front ends of the overtravel springs. Conductive copper busbars are fixedly connected to the top rear side of the conductive copper flexible connectors. Lever plates are rotatably connected to the rear ends of the multiple overtravel springs. Push rods are rotatably connected to the bottom of the multiple lever plates. Pull rods are fixedly connected to the front ends of the multiple push rods. Pull rods are fixedly connected to the front ends of the multiple pull rods. Grounding mechanisms are provided on the rear side of the frame.
[0006] Through the above technical solution: when the circuit breaker switch needs to be operated, rotating the rotating rod will drive multiple pull rods that are equidistant from it to move. The movement of the pull rods will cause the crank arm to rotate, causing the vacuum interrupter to slide on frame two. When the vacuum interrupter slides, its rear outer wall is slidably connected to the solid-sealed pole. The vacuum interrupter will slide along the inner wall of the solid-sealed pole. At the same time, the moving conductive rod fixedly connected to the rear end of the vacuum interrupter will also move. The rear end of the moving conductive rod passes through the solid-sealed pole. During the movement of the moving conductive rod, the bellows slidably connected to its outer wall will undergo compression or tension deformation. The bellows plays a role in buffering and storing energy, which can reduce the impact force generated when the vacuum interrupter moves, ensuring the smoothness of the switch operation, thereby making the moving conductive rod... The connecting rod, fixed at the rear end, also moves with the circuit. An overtravel spring is slidably connected to the outer wall of the connecting rod. As the connecting rod moves, the overtravel spring also expands and contracts accordingly. A conductive copper flexible connector is fixedly connected to the front end of the overtravel spring. A conductive copper busbar is fixedly connected to the top rear side of the conductive copper flexible connector, providing circuit isolation. A lever plate is rotatably connected to the rear end of the overtravel spring. As the overtravel spring expands and contracts, the lever plate rotates. A push rod is rotatably connected to the bottom of the lever plate. The rotation of the lever plate drives the push rod, which is fixedly connected to the front end of the push rod. The movement of the push rod enables the insulating pull rod to perform a grounding operation, thus ensuring the safety and stability of the entire circuit breaker switch during operation and achieving circuit on / off control functions. As a further description of the above technical solution: The grounding mechanism includes a sensor, the front side of which is fixedly connected to the rear side of frame one. A conductive busbar is fixedly connected to the rear side of the sensor. An output terminal is fixedly connected to the rear side of the conductive busbar. A grounding blade is rotatably connected to the bottom front side of the conductive busbar. A switch main grounding busbar is rotatably connected to the front end of the grounding blade. A drive crank arm is fixedly connected to the front end of the switch main grounding busbar. The front ends of the drive crank arms are all fixedly connected to the lower middle part of the rear side of frame one.
[0007] Through the above technical solution: the sensor is used to detect the energization status of the circuit in real time and transmit the signal to the control system. When the system is running normally, the current is output from the back of the sensor to the conductive busbar. The conductive busbar acts as a bridge for current transmission, guiding the electrical energy to the outgoing terminal to achieve connection with the external circuit. During circuit maintenance or fault handling, the grounding blade plays a key role. The bottom front of the grounding blade is rotatably connected to the conductive busbar, and the front end is rotatably connected to the main grounding busbar of the switch. When grounding operation is required, the drive crank arm rotates around a fixed point in the lower middle part of the rear side of the frame under the action of external driving force, driving the main grounding busbar of the switch to move, thereby causing the grounding blade to rotate around the connection point with the conductive busbar, and finally contacting the conductive busbar to form a grounding loop, introducing the residual charge or fault current in the circuit to the ground, ensuring the safety of personnel and equipment.
[0008] As a further description of the above technical solution: Multiple sensors are fixedly connected at equal intervals on the lower front side of the frame, and terminal blocks are fixedly connected to the front ends of the multiple sensors.
[0009] The above technical solution provides a stable support for the terminal block, ensuring that the terminal block is fixed in position.
[0010] As a further description of the above technical solution: A cabinet door interlock is fixedly connected to the rear right end of the frame one, and a closing interlock is fixedly connected to the bottom right side of the frame one.
[0011] The above technical solution enables the cabinet door interlock to restrict the circuit breaker when the cabinet door is open, preventing accidental operation of the circuit breaker while the cabinet door is open.
[0012] As a further description of the above technical solution: A mounting plate is fixedly connected to the middle right side of the frame, and a warning sign is fixedly connected to the right side of the mounting plate.
[0013] The above technical solutions serve to fix warning signs, provide a foundation for their installation, and convey important safety information and operational tips to operators.
[0014] As a further description of the above technical solution: Each of the multiple terminals has a connection hole on its front side, and a wiring block is slidably connected inside each of the multiple connection holes.
[0015] The above technical solution provides space for the installation and sliding of the connector block, which can slide inside the connection hole and make a tighter connection with the external wires.
[0016] As a further description of the above technical solution: A counter is fixedly connected to the upper right front end of the frame.
[0017] Through the above technical solution, maintenance personnel can understand the usage frequency and working status of the circuit breaker by using the data recorded by the counter, providing a reference for equipment maintenance and replacement.
[0018] As a further description of the above technical solution: An energy storage indicator is fixedly connected to the upper right rear end of the frame.
[0019] The above technical solution allows staff to observe the energy storage status through energy storage indicators.
[0020] This utility model has the following beneficial effects: 1. In this utility model, rotating the rotating rod drives the pull rod to push the isolating blade to close. At the same time, the moving conductive rod moves with the vacuum interrupter to make the contacts contact, and compresses the overtravel spring. When the circuit breaker is opened, the overtravel spring releases pressure and pushes the lever plate and push rod in the opposite direction. The two closing springs adopt an assembly structure of inner and outer springs with hanging plates at both ends, which effectively increases the closing function. The operation of isolating and opening is a single-hole operation, which can realize that isolation and grounding can be operated at the same time when the circuit breaker is open. When the circuit breaker is closed, grounding and isolation cannot be operated, which more effectively avoids misoperation.
[0021] 2. In this utility model, the insulation status is detected in real time by a sensor and the signal is transmitted to the control system. During normal operation, the current is connected to the external circuit through the conductive busbar and the outgoing terminal. During maintenance or fault, the drive crank arm rotates to drive the main grounding busbar of the switch, so that the grounding blade rotates and contacts the conductive busbar to form a grounding loop. This realizes the real-time monitoring of the circuit insulation status and reliable grounding protection function, effectively ensuring the safety of personnel and equipment and improving the stability of circuit operation.

The front ends of multiple pull rods 17 are fixedly connected to the rear side of frame 1 to ensure the installation stability of pull rods 17. Grounding mechanism 2 is provided on the rear side of frame 1. Grounding mechanism 2 facilitates the installation and fixing of circuit breaker switches. Specifically, the circuit breaker switch mainly consists of a frame module, a switch module, an isolating module, a grounding module, and a mechanism. The frame module acts as a general support. Three vacuum interrupters 4 are sealed in epoxy resin-sealed poles 8 as the main switches and are located in the upper part of the frame 3. The isolating module is located on the left side of the frame, the grounding module is located on the right side of the frame, and the mechanism is located at the front of the frame. The main shaft, isolating shaft, and grounding shaft are arranged longitudinally. The main shaft linkage lever plate 15 enables the three-phase switch poles to open and close simultaneously. A reliable linkage rod is provided between the isolating shaft and the grounding shaft, so that when the grounding shaft is operated to close or open, the isolating shaft is simultaneously operated to open or close. The circuit breaker's pull rod 7 is positioned below the solid-sealed pole 8, effectively reducing the overall size of the switch. The rotation of the mechanism's energy output spindle is transmitted through the pull rod to the lever arm fixed on the modular retainer, causing the sliding sleeve to slide left and right within the guide rod. This compresses the circuit breaker's closing overtravel spring 12 and opens the circuit breaker's contact point, enabling closing and opening. This transmission structure efficiently ensures the high energy holding force required by the circuit breaker during closing. The guide post in the sliding sleeve effectively provides guidance and support, allowing the moving contact of the vacuum tube to move linearly, greatly increasing the lifespan of the vacuum tube. It is used to control the circuit breaker's closed circuit, ensuring normal power transmission.

The front side of the sensor 201 is fixed to the rear side of the frame 1 by bolts to provide stable support for the sensor. A conductive bus 202 is fixedly connected to the rear side of the sensor 201 to guide the current to the subsequent circuit. A terminal 203 is fastened to the rear side of the conductive bus 202 by bolts to realize a reliable connection with the external circuit. A grounding blade 204 is rotatably connected to the bottom front side of the conductive bus 202 by a pin shaft, which can rotate around the shaft to realize the grounding function. The front end of the grounding blade 204 is rotatably connected to the main grounding bus 206 of the switch by a joint bearing to transmit driving force and ensure rotational flexibility. The front end of the main grounding bus 206 of the switch is fixedly connected to the drive crank arm 205 by a key to convert the rotational motion into linear motion. The front ends of the drive crank arms 205 are all fixedly connected to the lower middle part of the rear side of the frame 1 by bolts. Specifically, sensor 201 is used to detect the power-on status in real time. When the system is running normally, the current is output from the rear of sensor 201 to conductive bus 202. Conductive bus 202 acts as a bridge for current transmission, guiding electrical energy to the output terminal 203 to achieve connection with the external circuit. During circuit maintenance or fault handling, grounding blade 204 plays a key role. The bottom front of grounding blade 204 is rotatably connected to conductive bus 202, and the front end is rotatably connected to the main grounding bus 206 of the switch. When grounding operation is required, the drive crank arm 205 rotates around the fixed point in the lower middle part of the rear of frame 1 under the action of external driving force, driving the main grounding bus 206 of the switch to move, thereby causing grounding blade 204 to rotate around the connection point with conductive bus 202, and finally contacting conductive bus 202 to form a grounding loop, introducing the residual charge or fault current in the circuit to the ground, ensuring the safety of personnel and equipment.

Terminal blocks 19 are fixedly connected to the front ends of the signal sensors 18, enabling reliable connection between external wires and the internal circuitry of the circuit breaker. A cabinet door interlock 20 is fixedly connected to the rear right end of frame 1, preventing accidental operation of the circuit breaker when the cabinet door is open, thus ensuring operator safety. A closing interlock 21 is fixedly connected to the bottom right side of frame 1, and a mounting plate 22 is fixedly connected to the middle right side of frame 1, providing a mounting base for warning signs 23.

The energy storage indicator 27 allows the staff to see the energy storage status.
[0028] Working principle: When using this circuit breaker switch, when a closing operation is required, rotating rod 6 is rotated. The rotation of rotating rod 6 drives multiple pull rods 7 that are equidistantly connected to it to move. The front end of pull rod 7 pushes the isolating blade 5 to rotate around the rotation point between itself and the front end of the solid-sealed pole 8, causing the isolating blade 5 to close. At the same time, the vacuum interrupter 4 inside the solid-sealed pole 8 works under the action of related components. The moving conductive rod 9 is fixedly connected to the rear end of the vacuum interrupter 4 and passes through the solid-sealed pole 8. Its outer wall is slidably connected to a bellows 10 for sealing. 9 is connected to a connecting rod 11 at the rear end. The overtravel spring 12 on the outer wall of the connecting rod 11 is compressed during the closing process. The front end of the overtravel spring 12 is connected to a conductive copper flexible connector 13. The top rear side of the conductive copper flexible connector 13 is connected to a conductive copper busbar 14 to ensure the continuity of the circuit. The rear end of the overtravel spring 12 is rotatably connected to a lever plate 15. The bottom of the lever plate 15 is rotatably connected to a push rod 16. The front end of the push rod 16 is connected to a pull rod 17. The front end of the pull rod 17 is fixed to the rear side of frame 1. During closing, the compression of the overtravel spring 12 is transmitted through the lever plate 15 and the push rod 16, so that the vacuum interrupter 4 is closed. With good contact between the contacts, the circuit breaker is closed. When opening is required, the overtravel spring 12 releases pressure and rotates the rotating rod 6 in the reverse direction, reversing the process. After the isolating blade 5 opens, the moving conductive rod 9 moves backward under the action of the overtravel spring 12, causing the contacts in the vacuum interrupter 4 to separate, cutting off the circuit and realizing the opening operation. When the system is running normally, the current is output from the rear side of the sensor 201 to the conductive bus 202. The conductive bus 202 acts as a bridge for current transmission, guiding electrical energy to the output terminal 203 to achieve connection with the external circuit. During circuit maintenance or fault handling... The grounding blade 204 plays a crucial role. The bottom front side of the grounding blade 204 is rotatably connected to the conductive busbar 202, and the front end is rotatably connected to the main grounding busbar 206 of the switch. When grounding operation is required, the drive crank arm 205 rotates around the fixed point in the lower middle part of the rear side of the frame 1 under the action of external driving force, which drives the main grounding busbar 206 of the switch to move, thereby causing the grounding blade 204 to rotate around the connection point with the conductive busbar 202, and finally contact the conductive busbar 202 to form a grounding loop, introducing the residual charge or fault current in the circuit to the ground, ensuring the safety of personnel and equipment.
