Can, and ensure that vacuum interrupter has very high mechanical life.Vacuum switch is during division, and arc extinguishing chamber bellows are by flexible
Effect, by stress on ripple tube section, so the service life of bellows should be determined according to stroke repeatedly and using pressure.
The fatigue life of bellows is related with the heating temperature of operating condition, and vacuum interrupter is conductive after big short circuit current flow is segmented
The waste heat of bar is transferred on bellows, raises the temperature of bellows, when temperature is raised to a certain degree, will influence bellows
Fatigue strength.So how the service life that bellows is protected not to be damaged and extends vacuum interrupter is art technology
Personnel need to overcome the problems, such as.

Specific embodiment
As shown in Figs. 1-2, stent of the present invention, installation vacuum interrupter on the bracket, armature, with the armature phase
Mutual matched electromagnet, battery component and wireless switching, the electromagnet, the battery component, the wireless switching and
The electromagnet is sequentially connected electrically forming circuit, and the vacuum interrupter is equipped with insulation push rod, and one end connection for the push rod that insulate is true
Empty arc-chutes, the other end of the insulation push rod are connected on the side of the armature, and the armature is connected by resetting spring
To stent, the electromagnet is arranged at the back side that the armature is connected with the one side of insulation push rod.When wireless switching is closed, electricity
Magnet attracts the armature, and the armature overcomes the pulling force of the resetting spring to drive the insulation push rod disconnecting circuit.
The vacuum extinction device includes insulation shell, moving contact, static contact, moving conductive rod, static conductive rod and bellows,
Bellows one end is socketed on moving conductive rod, and the other end is fixed on insulation shell, among the bellows and moving conductive rod socket place
Equipped with thermal insulation layer, the moving conductive rod is placed in the fin that the part outside insulation shell is equipped with heat transmission.
Preferably, the thermal insulation layer is ceramic layer.
Preferably, the moving contact is elastic conduction column.
Preferably, the wireless switching is infrared switch, Bluetooth switch or RF switch.
Vacuum circuit breaker of the present invention can control the vacuum circuit breaker due to being provided with wireless switching by wireless signal
Switch, due to being provided with temperature sensor, ceramic heat layer and temperature controller, can realize the temperature to vacuum interrupter
Degree controls, and can also work normally vacuum circuit breaker under severe working environment so that the vacuum circuit breaker is at low ambient temperatures
It can also normal use.
The present invention has abandoned directly to be socketed on bellows one end on moving conductive rod and joins with moving conductive rod in the prior art
Dynamic structure, for traditional technology since moving conductive rod is directly contacted with bellows, heat transmitting is high, and bellows and moving conductive rod set
