Description
Technical field
The present invention relates to vacuum arc extinguishing chamber corrugated tube technical field, the vacuum interrupter ripple of specially a kind of bounce-proof
Pipe.
Background technique
Vacuum interrupter also known as vacuum switch tube are the core components of mesohigh power switch, and main function is to lead to
Crossing the excellent insulating properties of vacuum in managing makes after mesohigh circuitry cuts power supply blow-out and to inhibit electric current rapidly, avoids accident and meaning
Outer generation is mainly used in the transmission & distribution electric control system of electric power, is also applied to metallurgy, mine, petroleum, chemical industry, railway, wide
It broadcasts, communicate, the distribution systems such as industrial high-frequency heating.With energy conservation, section material, fire prevention, explosion-proof, small in size, the service life is long, maintenance cost
The features such as low, reliable for operation and pollution-free.Vacuum interrupter is divided into arc extinguishing chamber for breaker again from purposes and on-load switch is used
Arc-chutes, arc-extinguishing chamber of circuit breaker are mainly used for substation and electrical network facilities in power department, and on-load switch arc-chutes are main
Terminal user for power grid.
Dynamic/static contact in vacuum switch tube realizes the folding control to circuit by mutual contact with separating.Dynamic
In the making process of static contact, closing rebound can be generated by touching contact for the first time from contact and stably turning on.
In order to shorten bounce time when combined floodgate, Chinese patent CN2736910Y is disclosed and is touched in a kind of vacuum interrupter
The reinforcing rib of head support device.It includes reinforcing rib that it, which is constructed, and feature is to offer one or more on reinforcing rib top
Groove.This structure not only ensure that enough support strengths, but also guarantee there be the dynamic of certain snubber contact closing time
Can, the spring that contact generates when vacuum interrupter closes a floodgate is reduced, the reliability of product is effectively increased；Chinese patent
