High-voltage DC contactor

The utility model discloses a high-voltage direct-current contactor which comprises a ceramic combination, an exhaust pipe, a magnetizer, an armature housing, an armature, a return spring, a static iron core, a transmission rod, a contact bridge, an over-travel spring, a magnetizer insulating washer, a contact bridge insulating washer, a shell, a shell bushing, a coil outgoing line, a coil combination and a magnetic steel combination. According to the utility model, the auxiliary contact is additionally arranged outside the two static contacts, when the contactor is switched on, the transmission rod drives the contact bridge to be respectively contacted with the two static contacts and the auxiliary contact, each contact in a mutually disconnected state forms conduction, and meanwhile, theswitched-on auxiliary contact and the two static contacts can form an auxiliary conduction loop in pairs. The device is used for external linkage time sequence control or contactor self-locking and interlocking functions. 本实
