An isolated and grounded disconnect structure with simple operation

Abstract

The invention discloses an operable isolating and grounding circuit breaker structure. The structure herein includes an upper isolating cylinder and a circuit breaker. An upper end of the upper isolating cylinder is in fixed connection to an upper outlet seat. The upper isolating cylinder is provided with a vacuum arc-extinguishing chamber therein. The vacuum arc-extinguishing chamber is providedwith a transit chamber therebelow. Two sides of the transit chamber are each provided with a lead clamp. One end of the lead clamp is in fixed connection to a current transformer. A variation shaft isprovided with a gear therein. One side of the gear is provided with a ratch, and the ratch and the gear are both provided with a serrated knife thereon. When the ratch moves, the serrated knife on the ratch drives the serrated knife on the gear, such that the gear begins to rotate. The rotation of the gear drives the variation shaft to move up and down, and the variation shaft is fixedly providedwith a telescopic lever therebelow, such that the variation shaft can move more smoothly and swiftly. Also, the circuit breaker is easy and fast to operate. The disconnection can provide explicit disconnection distance and reduces danger to maintenance workers.

Description

technical field [0001] The invention belongs to the technical field of vacuum circuit breakers, and in particular relates to an isolation and grounding type circuit breaker structure with simple operation. Background technique [0002] Vacuum circuit breakers have the advantages of small size, light weight, suitable for frequent operations, and no maintenance for arc extinguishing. They are widely used in distribution networks. They are all named after high vacuum. Vacuum circuit breakers have the advantages of small size, light weight, suitable for frequent operation, and no maintenance for arc extinguishing. They are widely used in distribution networks. A brief history of development. Haus proposed a vacuum interrupter with a simple structure and obtained a design patent. In 1920, the Swedish Foga Company made a vacuum switch for the first time. [0003] During the use of vacuum circuit breakers currently on the market, due to the sensitivity of the circuit breakers, the...
