Less oil circuit breaker itself caused many of its structural characteristics of insecurity
One important reason is that the older less oil circuit breakers caused. Less oil circuit breaker itself caused many of its structural characteristics of insecurity, such as the impact of closing when the current, the DC system voltage fluctuations; circuit
mcb circuit breaker operating time is longer, affecting accident rapid removal of the fault point; caused due to years of operation switch aging, usually oil spills oil leakage
Voltage stabilizer often occur, so that the circuit breaker overhaul cycle is shortened, operating personnel should also increase
Air circuit breaker ; especially when a major accident cut off the fault current circuit breaker, it is likely to cause the circuit breaker injector even explosion. These factors have a serious impact on the company's safety and economic operation.
