Problems solved by technology

[0004] However, when the connector body and the inner crank arm in the above technology are connected in rotation, the part of the rotation connection between the two will produce greater wear after a long time of work. If it is not handled or replaced in time, it will increase the operating torque of the crank arm shaft, which is not conducive to the smooth operation of the circuit breaker

Embodiment 1

[0030] The inner wall of the swivel 5 corresponding to both sides of the ball 7 is connected with an elastic protective strip 17, and the annular sleeve 10 is respectively provided with an annular groove 18 at the corresponding sidewall position of the rotating rod 8 and the protective strip 17, so that The free end of the protective strip 17 extends into the interior of the annular groove 18 and is attached to the side wall; the protective strip 17 and the annular groove 18 can shield and protect the rollers and the elastic ring 12 exposed to the external environment. Protection, reducing water vapor or dust impurities falling to the ball 7 or the elastic ring 12, which will affect the life of the ball 7 and the elastic ring 12.

[0031] The side of the top of the elastic ring 12 close to the protective strip 17 is connected with a shaking strip 19, and the other end of the shaking strip 19 extends into the inside of the annular groove 18, and the corresponding annular grooves...

Abstract

The invention belongs to the technical field of high-voltage switches, and particularly relates to a high-voltage circuit breaker connector which comprises a body, one end of the body is connected with a transmission pull rod, the other end of the body is rotationally connected with an inner crank arm, and the other end of the inner crank arm is connected with a crank arm rotating shaft. A rotating ring is fixedly connected to the position, connected with the body, of the inner crank arm, a group of rolling grooves which are annularly and evenly distributed are formed in the inner ring side wall of the rotating ring, balls are rotationally connected into the rolling grooves, a rotating rod is rotationally connected into the rotating ring, and the other end of the rotating rod is fixedly connected with the end of the body; the connector body and the inner crank arm are rotationally connected, so that friction and abrasion when the connector body and the inner crank arm are rotationally connected are reduced, the service life of the connector is prolonged, the situation that the operating torque of a rotating shaft of the crank arm is increased after the connector works for a long time is reduced, and the circuit breaker can work smoothly and stably.

Description

technical field [0001] The invention belongs to the technical field of high-voltage switches, in particular to a high-voltage circuit breaker connector. Background technique [0002] The operating mechanism is the mechanism that controls the opening and closing operation of the circuit breaker. At present, the commonly used operating mechanisms mainly include electromagnetic operating mechanisms, spring operating mechanisms, pneumatic operating mechanisms and hydraulic operating mechanisms. Various types of circuit breakers, regardless of whether their arc extinguishing medium and working principle are the same, have the same basic requirements for the operating mechanism, that is, sufficient operating power and operating torque are required to ensure the opening and closing speed of the circuit breaker. At present, in the existing high-voltage circuit breakers, the operating mechanism transmits the operating torque to the transmission rod through the crank arm shaft and the...
