巴慕达手冲壶售后网点高压隔离

　　in110kVVoltage grade is above substation，Through a simple statistical discovery of a device maintenance work，Isolation switching related maintenance work has become a single device type for maintenance workload。There are many reasons why the isolation of isolation is faulty.，Early circuit breaker failure rate、Short inspection cycle，The circuit breaker is much higher than the failure rate of separation of isolation at the time.，Circuit breaker maintenance cycle is1～2year，The isolation switching cycle is4～5year。For the convenience of the circuit breaker，Spacer design is generally used 巴慕达电水壶在那修 in substations to isolate the circuit breaker as much as possible，Reduce the impact of circuit breaker maintenance and repair on other equipment;This BALMUDA中国维修网点 is why the interval in the substation is basically based on the circuit breaker.。All sides of the circuit breaker are set off，In the double bus system，The bus side also sets two isolation off。If you take into account the equipment such as bus voltage transformers, you can only need to set the isolation switch.，And busbars need to set a ground switch separately，In fact，in110kVAnd above，The quantity of isolation switch is much larger than the number of circuit breakers.、Low price，Equipment manufacturers have insufficient degree of importance，Input energy limited;on the other hand，The research and development improvement focus of isolation switch is concentrated in controlling product costs by 巴慕达净化器售后服务 optimizing product selection.。and so，The reliability of isolation switch is not significantly improved，Now its average maintenance cycle is6year。It 巴慕达音箱维修 is especially worth mentioning.，Domestic equipment manufacturers compete with foreign advanced equipment manufacturers，Often the order through the price advantage，Further leading to domestic separation off equipment product failure rate is higher。
