Photoelectric controlled modular intelligent vacuum switch with phase selection function

Abstract

Vacuum switch as a great potential for development of new power switch, in the low voltage level has a strong advantage, but to the development of high-voltage level encountered a relatively large resistance. This paper provides a kind of phase selection function, photoelectric control, with multi-take energy operate the power system, with permanent magnetic actuator of the modular smart vacuum switch. Its structure includes smart selection phase controller, power drive unit, multi-taking energy operate power systems, permanent magnet actuator, vacuum interrupter chamber and the outer insulation systems.
