Description

Technical Field

[0001] The utility model relates to the technical field of circuit breakers, in particular to a circuit breaker device with a simulated permanent magnet mechanism. Background Art

[0002] The permanent magnet circuit breaker adopts a bistable permanent magnet mechanism with a built-in undervoltage release, and is integrated with a mechanical manual release to make manual opening light and reliable. The combination of permanent magnet mechanism opening and spring opening makes the distribution of opening speed more ideal. Compared with spring-operated mechanism circuit breakers, the number of moving parts is greatly reduced, which greatly improves its reliability and mechanical life. It is an ideal alternative to spring-operated mechanism type circuit breakers.

[0003] Existing permanent magnet mechanism circuit breakers all use the permanent magnet mechanism drive control module to output pulsed DC to discharge the coil. The time is in milliseconds. If the voltage is insufficient or the capacitance is insufficient, the permanent magnet mechanism circuit breaker is difficult to close. Sometimes the mechanism is stuck or the electromagnetic coil is damaged, and the permanent magnet mechanism circuit breaker cannot be closed either. In order to determine whether the permanent magnet mechanism circuit breaker has a problem with the permanent magnet mechanism drive control module, or whether the mechanism is stuck or the electromagnetic coil is damaged, a device simulating a permanent magnet mechanism circuit breaker has been specially developed. Utility Model Content

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solution: a simulated permanent magnet mechanism circuit breaker device, comprising a base, a coil provided on the top of the base, a permanent magnet mechanism connected through the top of the coil, an intermediate plate provided on the surface of the permanent magnet mechanism, a top plate provided on the top of the coil, fixed plates fixedly connected to both sides of the bottom of the top plate, and a ten-core plug socket and an eight-core plug socket connected through the surface of the fixed plate on the left side.

[0006] Preferably, a threaded rod is fixedly connected to the top of the permanent magnet mechanism, and a nut is provided on the top threaded sleeve of the surface of the threaded rod.

[0007] Preferably, a spring sheet is sleeved on the surface of the threaded rod, and a support seat is sleeved on the surface of the threaded rod, and the bottom of the spring sheet contacts the inner wall of the support seat.

[0008] Preferably, both the front and rear sides of the top of the base are fixedly connected with vertical plates, and the top of the vertical plates is fixedly connected to the bottom of the top plate.

[0009] Preferably, the top of the intermediate plate is connected to a support plate by screws, and the surface of the support plate is connected to a position sensor by screws.

[0010] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0011] This utility model has an integrated module design and is easy to carry. The control circuit inlet and outlet lines are hot-dip plug-in, which is convenient for on-site wiring. It has a contact locking function and does not affect the normal operation of the permanent magnet mechanism circuit breaker. The 10-core plug on the secondary control power inlet side simulates a real permanent magnet mechanism circuit breaker and has built-in opening and closing buttons, which can immediately determine the cause of the fault.

[0018] See also Figure 1-Figure 5 A simulated permanent magnet mechanism circuit breaker device includes a base 1, a coil 2 is provided on the top of the base 1, a permanent magnet mechanism 3 is connected to the top of the coil 2, an intermediate plate 4 is provided on the surface of the permanent magnet mechanism 3, a top plate 5 is provided on the top of the coil 2, and a fixed plate 6 is fixedly connected to both sides of the bottom of the top plate 5, and a ten-core plug-in socket 7 and an eight-core plug-in socket 8 are respectively connected to the surface of the fixed plate 6 on the left side. The permanent magnet mechanism 3 uses the magnetic field of the permanent magnet to generate mechanical force to drive the opening and closing of the circuit breaker contacts. The operating coil 2 is used to control the magnetic field change of the permanent magnet mechanism 3, thereby realizing remote control and automatic protection of the circuit breaker state. The permanent magnet mechanism 3 includes an insulating connecting rod.

[0019] See also Figure 3 The top of the permanent magnet mechanism 3 is fixedly connected with a threaded rod 9, and a nut 10 is provided on the top thread sleeve of the surface of the threaded rod 9.

[0020] See also Figure 3 The surface of the threaded rod 9 is covered with a spring sheet 11, and the surface of the threaded rod 9 is covered with a support seat 12. The bottom of the spring sheet 11 contacts the inner wall of the support seat 12. By setting the nut 10, the top of the spring sheet 11 can be limited and compressed, and the compression depth of the spring sheet 11 can be adjusted. By setting the spring sheet 11, the return of the threaded rod 9 is facilitated.

[0021] See also Figure 1 The front and rear sides of the top of the base 1 are fixedly connected with vertical plates 13, and the top of the vertical plates 13 is fixedly connected to the bottom of the top plate 5. By setting the vertical plates 13, the top plate 5 is reinforced and supported, thereby improving the stability of the simulation device.

[0022] See also Figure 3 The top of the middle plate 4 is connected to a support plate by screws, and the surface of the support plate is connected to a position sensor 14 by screws. By setting the position sensor 14, the moving position of the permanent magnet mechanism 3 can be detected to determine the closing and opening status of the circuit breaker device.

[0023] When in use, first confirm that the running or stopped permanent magnet mechanism circuit breaker is a faulty circuit breaker, then take out the ten-pin dial plug on the secondary control power input side (the running one can keep the primary working power deducted from the secondary control power), and also take out the eight-pin dial plug on the secondary control power output side (permanent magnet coil line) (the running one can keep the primary working power deducted from the secondary control power), and insert the ten-pin dial plug on the secondary control power input side to the permanent magnet mechanism 3 drive control module, and insert the eight-pin dial plug on the secondary control power output side of the permanent magnet mechanism 3 drive control module into the eight-pin dial female connector of the simulated permanent magnet mechanism 3 circuit breaker. Connect the simulated permanent magnet mechanism circuit breaker to an external DC48V power supply, or use the internal battery of the permanent magnet mechanism 3 drive control module. By simulating a real permanent magnet mechanism circuit breaker with its own opening and closing buttons, perform opening and closing operations on the simulated permanent magnet mechanism circuit breaker. If it can open and close normally, it proves that the permanent magnet mechanism circuit breaker of the main body is faulty. If it cannot open and close normally, it proves that the permanent magnet mechanism drive control module of the main body is faulty.

[0024] In summary, the simulated permanent magnet mechanism circuit breaker device, through the coil 2, permanent magnet mechanism 3, middle plate 4, top plate 5, fixed plate 6, ten-core plug socket 7, eight-core plug socket 8, threaded rod 9, nut 10 and spring sheet 11, solves the problem that the permanent magnet mechanism circuit breaker is difficult to close due to insufficient voltage or insufficient capacitance, and sometimes the mechanism is stuck or the electromagnetic coil is damaged, and the permanent magnet mechanism circuit breaker cannot be closed, and the situation of being unable to close is difficult to judge.
