The difference between more oil circuit breaker and less oil circuit breaker: 

  1. Under normal circumstances can be understood in different circuit breakers and less oil and more oil circuit breaker literally,
  2. oil circuit breaker interrupter more oil, less oil and less oil circuit breaker interrupter.
  3. Whether oil circuit breaker or less oil circuit breakers, there are oil quenching medium, when the dynamic and static contact of circuit breaker, oil is charged into or discharged at high speed interrupter, more oil and less oil depends on the structure interrupter. More oil circuit breakers and less oil every oil-filled circuit breakers, its role is arcing, heat dissipation and insulation.
  4. Risk of extinguishing the oil not only in the event of failure may cause an explosion, and due to high temperatures after the explosion splash the oil in the oil circuit breakers, the formation of a large area of ​​the combustion, causing phase short circuit or earth fault, disruption of normal power system run the accident and even cause severe personal injury or death. Currently basically been decommissioned oil circuit breaker, a vacuum circuit breaker is generally substitute, SF6 circuit breakers (SF6 circuit breakers and vacuum circuit breakers having small compared to the volume of oil circuit breaker for breaking the ability strong, more interrupting large capacity advantage).
