Abstract:
An improved circuit interrupter for high voltage and low current provides reactor and capacitor switching functions with fewer serial interrupters. Improved electrical field configuration is provided by moving and stationary contact shields, surrounding the main contacts, which aid the plain break operation of the device by elimination of critical points of dielectric stress. The plain break feature provides less mechanical complexity and consequent higher reliability.
