摘　　要：在10kV电压等级的少油断路器中,由于在开断大电流和小电流时,对空气室的体积有不同的要求,同时选择合理的油气分离器,可以实现良好的冷却作用和分离油气的能力,避免出现喷油的事故。因此要重视少油断路器的空气室及油气分离器对开断能力的影响。In the oil-minimum brenker of 10kV,when heavy current and small current are switched off,they have different requirements to air cell volume. If a rational gas oil separator is selected,it can achieve fine cooling effect and separating oil gas ability to avoid oil injection. Thus it is important for effect of the air cell of the oil-minimum breaker and gas oil seperator on breaking capacity.
