High-voltage vacuum circuit breaker having protection

Abstract

The invention discloses a high-voltage vacuum circuit breaker having protection. The high-voltage vacuum circuit breaker comprises a circuit breaker and a protection box, wherein a support plate is fixedly connected to the bottom of the circuit breaker, first threaded rods are in threaded connection with two sides of the bottom of the support plate, a threaded pipe is fixedly connected to the bottom of each first threaded rod, a press disc is in threaded connection with a surface of the threaded pipe, and a cushion pad is connected to an inner cavity of the threaded pipe in a sliding way. By application of the circuit breaker, the protection box, the support plate, the first threaded rods, the threaded pipes, the press discs, the cushion pads, support rods, fixed pieces, a base, shockproofsprings, second threaded rods, reset springs, fixed plates and rubber pads in a matching way, the tension degree o the shockproof springs can be conveniently adjusted, the shockproof springs cannot be soft, and the protection performance of the circuit breaker is improved; and meanwhile, the stability of the high-voltage vacuum circuit breaker is also improved, the influence of an external forceon the circuit breaker is reduced very well, so that the circuit breaker is protected very well.

Description

technical field [0001] The invention relates to the technical field of high-voltage vacuum circuit breakers, in particular to a protective high-voltage vacuum circuit breaker. Background technique [0002] The high-voltage vacuum circuit breaker is named for its high-vacuum arc-extinguishing medium and the insulating medium of the contact gap after arc-extinguishing. It has the advantages of small size, light weight, suitable for frequent operation, and no maintenance for arc-extinguishing. It is used in power distribution The application in the network is relatively popular. Vacuum circuit breakers can be used as protection and control of electrical equipment in industrial and mining enterprises, power plants, and substations. They are especially suitable for places that require no oil, less maintenance, and frequent operations. It is used to control and protect high-voltage electrical equipment in central cabinets, double-layer cabinets, and fixed cabinets. At present, mos...
