Power system vacuum circuit breaker maintenance platform

Abstract

The invention provides a power system vacuum circuit breaker maintenance platform. The power system vacuum circuit breaker maintenance platform comprises a frame, a longitudinal beam arranged on the frame, a carrying platform connected with the longitudinal beam in a sliding mode, an operation box arranged on the longitudinal beam, a winding roller arranged in the operation box, an on-beam hangingwheel arranged at the top end of the longitudinal beam, a carrying hanging wheel arranged on the carrying platform, a wire disengaging preventing device arranged on the operation box, a transverse positioning device arranged on the frame, and a longitudinal positioning device arranged on the frame. Once the carrying platform touches the frame, and a crank is reversely shaken continuously, a steelwire rope is loosened; a ratchet wheel and a pawl are locked under the action of a tension spring, so that the crank cannot be continuously reversely shaken, and therefore, maintenance vehicle faultscaused by wire disengagement and even the disordered winding of the steel wire rope are avoided; and transverse positioning and longitudinal positioning ensure that the maintenance platform is completely locked, when a pull shaft sleeve and a rotating shaft are on the same straight line, and locking failure cannot be caused by the wrong touching of the pull shaft sleeve.

Description

technical field [0001] The invention relates to the field of a vacuum circuit breaker operation and maintenance platform, which is used to realize the moving in and out of a protection box for the vacuum circuit breaker, in particular to a power system vacuum circuit breaker maintenance platform. 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 both high vacuum; it has the advantages of being suitable for frequent operation, arc extinguishing without maintenance, and is widely used in distribution networks , Circuit breakers can be configured in central cabinets, double-layer cabinets and fixed cabinets as control and protection of high-voltage electrical equipment. [0003] Vacuum circuit breaker mainly consists of three parts: vacuum interrupter, electromagnetic or spring operating mechanism, bracket and its structure diagram. Other components are as...
