If the vacuum degree of the vacuum interrupter , which is used online in a vacuum breaker , is lower than an amount of magnitude , it will lead to the vacuum breaker cannot switch off normally . this will affect and damage to the power transformer system working in order 運行中的真空開關(guān),其真空滅弧室的真空度若低于一定數(shù)量級,就可能導致真空開關(guān)不能正常開斷電路,而影響配電系統(tǒng)的正常供電,這將造成極大的危害。
