Vacuum Circuit Breaker Vacuum Circuit Breaker Technical Standards

Usually divided into a plurality of voltage levels. Low pressure type generally used for explosion-proof electrical use. Like coal and so on.
Edit this paragraph vacuum circuit breaker main structure consists of three main parts: the vacuum interrupter, mcb circuit breaker or spring actuator, brackets and structure his parts.
Vacuum Circuit Breaker Vacuum Circuit Breaker technical standards in our country over the past decade has mcb circuit breaker development. Products from the past ZN1 ~ ZN5 several varieties grown to tens of multiple models, varieties, rated current up to 5000A, 50kA breaking current reaches a good level, and has been developed to voltages up to 35kV level.
Before the 1980s, the development of vacuum circuit breaker is in its infancy, technically keep groping, it can not develop technical standards until 1985 after the development of relevant product standards.
