Epoxy Resin Spouts Embedded Poles for ABB VD4 Vacuum Circuit Breaker

Vacuum circuit breaker pole, relates to a kind of high voltage vacuum switch with arc extinguishing or arc prevention device. With epoxy resin shell, vacuum interrupter chamber and other parts of the primary conductive circuit, vacuum interrupter chamber and other parts of the primary conductive circuit with epoxy resin cast into the shell, dynamic conductive block and the lower outlet terminal with spring coupling. The assembly process is simplified, the insulation reliability is high, from external forces and external environmental pollution, eliminating the use of ceramic material vacuum interrupter chamber and the use of epoxy resin casting shell between the contraction force inconsistent stress, to avoid damage to the vacuum interrupter chamber or epoxy resin casting body. Because of the sliding connection method of contact finger spring between the dynamic conductive block and the lower outlet terminal, the structure is simple and the contact resistance is small, especially suitable for the case of high current, which can be used for the control and protection of electrical equipment in power stations, distribution stations and substations, and suitable for frequent operation places.
