Description

Technical Field

[0002] Direct-acting circuit breakers are a type of circuit breaker that performs closing operations based on the linear motion of the moving contact. Usually, a simple transmission mechanism is used to directly drive the moving contact to perform opening and closing operations. Conventional direct-acting circuit breakers use a spring mechanism for their transmission mechanism, which usually includes a ratchet, a pawl, a transmission shaft, a trip shaft, etc. The manual or electric operating mechanism can achieve fast closing and opening operations, but it cannot meet the requirements of slow closing and opening operations. It does not have the functions of slow adjustment and specified stroke measurement. In the prior art, when a direct-acting circuit breaker is closed or opened, the moving and static contacts of the closing or opening operation run fast and the moving mass of the contacts is large, resulting in a large impact on the overall switch, which is not conducive to the maintenance of mechanical life and electrical insulation performance. It is currently impossible to check the running-in status of components in different position states without disassembling the working conditions of the mechanism body.

[0003] Taking into account the arc and impact generated in the process of opening and closing during operation, under load conditions, the moving and static contacts of the arc extinguishing chamber and the moving parts have a great comprehensive impact. The existing direct-acting transmission systems are all triggered to the final state of closing and opening, and there is no integrated slow adjustment component, so the slow positioning inspection of the process reproduction of the working condition cannot be realized.

[0004] At present, the test adjustability and assembly and maintenance convenience of direct-acting circuit breakers are relatively poor, and it is impossible to more efficiently conduct insulation tests, mechanical property tests and other tests, and quantitative inspections of operation and maintenance projects.

[0033] Specifically, a transition sealing guide plate 27 is provided at the center of the top plate, a guide sleeve 28 is provided in the middle of the transition sealing guide plate 27, and the top end of the transition connecting rod 14 is connected to the insulating transmission rod 12 through the guide sleeve 28; the transition connecting rod 14 can drive the insulating transmission rod 12 to move up and down.

[0034] In some embodiments, a closing rotation positioning member 31 and an opening rotation positioning member 30 are provided at both ends of the transition connecting rod 14 .

[0035] Optionally, the closing rotation positioning member 31 may be a locking nut, which is threadedly connected to the transition connecting rod 14. The opening rotation positioning member 30 may be a set screw, which is threadedly connected to the transition connecting rod 14.

[0041] According to the embodiment of the present application, the slow opening and closing action device 1 is integrated in the transmission box 2. After the power supply of the controller is cut off, the capacitor ensures that the discharge is complete, the electric repulsion mechanism 3 loses power, and enters the manual slow opening and closing action mode.

It is also possible to position and adjust the key control quantity parameters of the arc extinguishing chamber such as the stroke and the opening distance based on the test needs of the user. The electric repulsion mechanism 3 of this embodiment receives the electric energy provided by the energy storage control component 4, discharges instantaneously to generate electromagnetic repulsion, thereby driving the transition connecting rod 14 and the insulating transmission rod 12 to move, thereby realizing the opening and closing operations of the circuit breaker.
