| Abstract: | In this paper, on the basis of CJ20-40 contactor, various structures of arc quenching systems are designed, and blow-out magnetic field of contact is calculated with integral equation method. Through the tests, the re-ignition rates of arc under various structures are obtained. Meanwhile, the influences of width and number of slot in multiple-narrow slot chamber to arc movement and extinction under the actions of different self-exciting blow-out magnetic field are investigated, and therefore, the optimal arc quenching system for CJ20-40 contactor is obtained. |
