A maintenance platform for vacuum circuit breakers in power systems

Abstract

The invention proposes a maintenance platform for a vacuum circuit breaker in a power system, which includes a vehicle frame, a longitudinal beam arranged on the vehicle frame, a carrying platform slidingly connected with the longitudinal beam, and an operation box arranged on the longitudinal beam, which is arranged in the operation box The winding drum, the beam hanging wheel set on the top of the longitudinal beam, the carrying hanging wheel set on the carrying platform, the anti-offline device set on the operation box, the lateral positioning device set on the frame, set on the frame First, when the carrying platform touches the frame and continues to shake the crank handle, the wire rope will loosen, and the ratchet pawl will be locked under the action of the tension spring, making it impossible to continue to shake the crank handle, avoiding off-line or even wire rope The disordered winding causes the failure of the maintenance vehicle; secondly, the lateral positioning and longitudinal positioning ensure that the maintenance platform is completely locked, and when the shaft sleeve is pulled in the same line as the rotating shaft, Wu Peng pulling the shaft sleeve will not cause locking failure.

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...
