The Plateau type monopole high voltage vacuum contactor is designed for the special requirements of high voltage electrical products in high altitude areas. The installation altitude can reach 3500 meters. The switch is used as an indoor device in single-phase power system with rated working voltage up to 12kV and rated working current up to 630A. It can be used for remote switching, closing, frequent starting and controlling the load loop of high-voltage electrical equipment.
Contactor adopts high voltage and low voltage control circuit and main circuit layout structure, this kind of arrangement direct-viewing, safe and reliable, easy to install and maintain.Permanent magnetic actuator with permanent magnet contactor, middle ndfeb material is placed, after electrify to complete the closing coil, and the permanent magnets to keep, to release the magnetic field generated by the coil and permanent magnet opposite after offset, the counterforce spring brake assist. For electricity to maintain contact, after when coil charged, make through axial stud valve dynamic contact motion and static contact contact, make the contactor is in closed position, after the coil power, under the influence of reaction springs, dynamic and static contact apart, contactor in the breaking state
