Less oil circuit breaker role of transformer oil

The use of transformer oil or oil as a dedicated circuit breaker contact between the insulation and arc-quenching medium, and the insulation of the circuit breakers with solid insulation. Less oil circuit breaker transformer oil's role and interrupter  air circuit breaker  types and more oil is basically the same, but the fuel consumption is a lot less than the oil circuit breaker. Typical outdoor high-voltage circuit  mcb circuit breaker  less oil as shown schematically, which contains interrupter, intermediaries boxes, porcelain pillar and base, and several  Circuit breaker . Less oil circuit breakers are mainly developed European countries, the purpose is fuel efficient. In the 1940s, less oil circuit breaker breaking capacity and service life are very limited.
