Varför är det nödvändigt att göra AC Hipot -testning för brytaren?
The power frequency withstands voltage test(AC hipot test) is an important method for evaluating the insulation performance of breakers, switchgear, and other breakers. The AC hipot testing examines whether the circuit breaker can withstand the high voltage without breakdown or damage, through simulating the overvoltage conditions that the equipment may encounter during actual operation. AC hipot testing helps ensure product quality and provides En stark garanti för säker drift av kraftsystemet för switchgear -tillverkare .
Vad är standarden för AC Hipot -testning för brytare?
During conducting the power frequency withstand voltage test, the test voltage for circuit breakers is generally confirmed at 80% to 100% of the test value when ex-factory. The factory value is the performance indicator set by the manufacturer when the product is manufactured, representing the working capability of the circuit breaker under ideal conditions. The factory value enables a more accurate assessment of the performance of the circuit breaker in actual Använd, genomföra motståndstestet baserat på .
