Product Introduction
DVM-99 Vacuum Interrupter Tester
It is very important to test the vacuum degree of the vacuum switch regularly. The traditional detection method is the "withstand voltage method", that is, when the vacuum switch is in the off state, a certain voltage is applied between the static and static contacts to detect the size of the leakage current, to infer the quality of the vacuum tube.
The advantages of this method are: simple operation; The disadvantage is that the vacuum tube can only be qualitatively detected, and the vacuum can not be accurately distinguished between 10-4 and 10-1Pa, so it is impossible to judge the development trend of leakage, that is, how much leakage is the same vacuum switch compared with the last time.
DVM-99 Vacuum circuit breaker tester, without removing, directly measures the vacuum degree of the vacuum interrupter. With the quantitative measurement, it means not only can it measure whether the vacuum degree is within the normal range, but also for some vacuum circuit breakers that leak faster, it can compare with the measuring results of past years, and infer the service life to prevent accidents. This product is a compact, lightweight and compact model, with a short test time, reliable measurement results, good stability, and high precision, fully functional, and is the ideal instrument for quantitative measuring vacuum circuit breakers.
