High-voltage vacuum circuit breaker with anti-tripping function

Abstract

The invention provides a high-voltage vacuum circuit breaker with an anti-tripping function, relates to the technical field of circuit breakers, and solves the problems that the anti-tripping of a switch cannot be realized when the switch is pressed and the impact protection of hands cannot be realized when the anti-tripping is realized, and that unpowered heat dissipation cannot be realized by realizing mutual linkage between a a heat dissipation structure and the cable swinging with wind by structure improvement . The high-voltage vacuum circuit breaker with the anti-tripping function comprises a circuit breaker box body, the circuit breaker box body is fixedly connected with an elastic bayonet lock through a bolt, and the circuit breaker box body is provided with a sliding structure. When a pressing switch is pressed, the elastic bayonet lock is in an extending state, and the pressing switch is in a limiting state at the moment; a baffle is welded on the pressing switch, and the elastic bayonet lock is in contact with the top end surface of the baffle when the push switch is pressed, so that the elastic bayonet lock can be prevented from being in contact with a hand to cause hand injury when extending out.

Description

technical field [0001] The invention belongs to the technical field of circuit breakers, and more specifically relates to a high-voltage vacuum circuit breaker with anti-jump function. Background technique [0002] "Vacuum circuit breaker" is named because the arc extinguishing medium and the insulating medium of the contact gap after arc extinguishing are high vacuum; it has the advantages of small size, light weight, suitable for frequent operation, and no maintenance for arc extinguishing. It is widely used in power grid. [0003] For example, the application number: CN201610985041.X, the present invention provides a high-voltage vacuum circuit breaker, including a switch tube installation box, an opening and closing control box, a linkage rod, three connecting rods, a driving servo, an opening and closing handle, and a tension spring and three vacuum switches. The vacuum switching tube of the high-voltage vacuum circuit breaker uses a rotary drive mechanism to realize ...

Problems solved by technology

[0007] In order to solve the above technical problems, the present invention provides a high-voltage vacuum circuit breaker with an anti-jump function to solve the existing problem that the existing device cannot realize the anti-jump of the switch when the switch is pressed, and cannot realize the anti-jump The impact protection of the hand can be realized at the same time; moreover, most of the existing devices are equipped with heat dissipation fans to realize the heat dissipation of the internal electrical components, but the heat dissipation structure and the swinging of the cable with the wind cannot be realized through the improvement of the structure. The problem of no power cooling
