For one of the important content of most vacuum circuit breaker repairs based on condition of component.Actually, vacuum level of vacuum arc-quenching chamber is also to determine very
One of the principal element of empty arc-chutes break performance, in order to realize that disjunction and the arc extinguishing of electric current, the pressure in vacuum extinction room are answered
1.33 × 10 should be not higher than-2Pa, the reduction of vacuum degree will directly affect the break performance of vacuum circuit breaker.Since vacuum switch passes through
The use for spending many years, with during drop-out current contact material generate gas increase and vacuum interrupter itself is faint
The reduction that leakage will cause vacuum degree in arc-chutes nor affects on the reality of switch but as long as not generating leakage under normal circumstances
It cut-offs.It is final the result is that arc-chutes vacuum regardless of leakage point size and leakage speed but when vacuum interrupter generates leakage
Environment will be destroyed completely, is not taken timely measure such as and is replaced, once generating switch division movement will cause seriously to ask
Topic and accident, it is therefore desirable to a method of simple effective and controllable cost energy real time on-line monitoring vacuum degree and judgement leakage
And realization device.
In Vacuity of Vacuum Circuit Breakers monitoring technical field, off-line monitoring technology is widely used.Off-line monitoring needs to break
Electricity detects system, therefore certain influence can be generated on power consumer;After power-off, vacuum interrupter indoor design condition and operation
State is inconsistent, to influence judgment accuracy.How to realize that on-line monitoring is always a problem, because of the life of vacuum interrupter
Produce need integrally at a high temperature of 800 degree or sos progress material welded seal and vacuumize, therefore generally built-in sensor without
Method bears such environment, thus can not reflect its internal vacuum degree by being previously implanted sensor progress gas pressure measurement
Or leakage situation.
