High Voltage vacuum circuit breaker tester Vacuum Switch circuit-breaker analyzer

Vacuum switch vacuity tester circuit breaker analysis Introduction:

In JB8738-1998(vacuum interrupter arc chamber of 3.6-40.5KV AC high voltage switchgear)established by high-voltage switchgear National Standardization Technical Committee, it is prescribed that the internal gas pressure measurement and allowable storage time limit inspection must be executed for any user and producer of interruption arc chamber of high-voltage vacuum switchgear. At the same time, in National Standardization -JB8738-1998, it is also noticed that allowable storage time limit of interruption arc chamber should be 20 years, and internal gas pressure of the vacuum interrupter arc chamber should be less than 6.6×10^-2Pa.
