AEW-ZN85-40.5ZN85-40.5/T(3AV3)indoor handcar vacuum circuit breaker is suitable for three-phase,Ac50Hzwith 40.5KV rated voltage. It can be used for industrial and mining enterprises, power plants and substations as load current and overload current fault current, and is suitable for the occasion with frequent operation. The circuit breaker adopts an upper and lower arrangement structure to effectively reduce the depth of the circuit breaker. It adopts the composite insulation structure, the three-phase arc extinguishing chamber and the associated electrified body. Separated by three independent epoxy insulation cases, the circuit breaker meets the air distance and creepage requirements under normal operating conditions after the composite insulation structure and it effectively reduces the size of the circuit breaker. The main conductive circuit vacuum interrupter and the dynamic and static conduclive conneclion are installed in the insulation tube, so that the phase to phase distance is only 300mm.The main circuit electrical connections are all fixed connections with high reliability.
