Abstract
A compact switchgear system employing a number of modular components that plug into their mating interface and are maintained in electrical isolation employing solid insulation in a manner that substantially shields the electrical conducting portions of the assembly from contact with lower voltage portions of the system. The assembly is primarily made up of five modules. A multi-phase load connector having integral current monitoring transformers for each of the respective phases; a voltage monitoring transformer which plugs into the load connector; an in-line actuator and vacuum interrupter module, provided for each phase, which plugs into the load connector; a three position vacuum switch connected between the vacuum interrupter module and the line or ground; and an electronic control module which receives inputs from the current and voltage monitors, circuit relays, vacuum interrupter/in-line actuator module, and temperature sensors, and provides programmed, controlling outputs to the in-line actuators of the respective vacuum interrupter modules.
