用于中压交流回路中的断路器，利用阴极辉点现象的方法和拉长电弧去游离的方法相结合。
In breakers for medium-voltage ac circuits, the cathode-spot phenomena may be combined with methods for bringing about the lengthening and deionization of the arc path.
用于低压交流回路的断路器，由于在过零换向电压不能满足再次阴极放电起弧的需要，因此具有容易灭 弧的优点。
In breakers for operation in low-voltage ac circuits, advantage is taken of the voltage required to establish a cathode spot.
