Type chopper is compared, have safe and reliable, life-span length, maintenance load are little, environment is the most contaminated
Advantage.
Vacuum interrupter is the core of vacuum circuit breaker.In order to realize disjunction and the arc extinguishing of electric current,
The pressure of vacuum extinction indoor is generally not more than 10-2Pa.Therefore, vacuum is to determine vacuum extinction
One of principal element of break performance of room, the reduction of vacuum will directly affect opening of vacuum circuit breaker
Cutting capacity, will cause it to cut-off complete failure time serious.Therefore, practical application area in the urgent need to
Measure and the vacuum of vacuum interrupter in record operation.
In actual application, the method for testing of vacuum level of vacuum arc-quenching chamber mainly has: industrial frequency withstand voltage method, height
Frequently electric discharge, observational method, spark meter method, getter color change criterion, high frequency electric method,
Coupling capacitance method, magnetic control discharge method, electro-optical conversion method and ray method etc..
In above-mentioned several vacuum monitor method, adopted by vacuum interrupter manufacturer at present
The most universal method be impulse magnetron electric discharge, but it can not realize on-line testing.Power frequency
Resistance to platen press is only used for observation measurements, determines that vacuum interrupter whether can normal breaking and making electric current.
Electro-optical conversion method is good at efficacy in laboratory, but is influenced by temperature at the scene, can accurately be not quantitative
Measurement of vacuum.
Therefore, it is necessary to provide a kind of Vacuity of Vacuum Circuit Breakers on-line measuring device.
Summary of the invention
The purpose of this utility model is to provide a kind of Vacuity of Vacuum Circuit Breakers on-line measuring device.
The technical solution of the utility model is as follows: a kind of Vacuity of Vacuum Circuit Breakers on-line measuring device,
The first temperature sensor, the second temperature sensor, control module and the monitoring device connected including signal,
