Transformer oil or circuit breaker for oil as an insulating and arc-quenching medium

The use of transformer oil or circuit breakers for oil as an insulating and arc-quenching medium breaker. Its main circuit and arc conductive element is placed in a special oil filled  mcb circuit breaker  oil or ground tank shell, cabinet generally cylindrical or oval cylindrical, fuel consumption is large, such as 12kV oil circuit breaker oil level number  electric meter , 252 kV class needs more than 40 tons of oil. For fuel, the development of the 1950s had been case-shaped oil circuit breaker, but soon to be rapidly replaced by less oil circuit breakers. Structural principle of oil circuit breaker as shown.
