Abstract
Abstract Disclosed is an electrical bushing connector (10) designed to complete a power circuit connection to a transformer or the like typically employed in a primary power distribution system. The connector will also afford capability to switch high power electrical loads. The connector will mate with and make electrical connection with a loadbreak terminator (50) as used in such systems so that an electrical circuit carrying high currents at elevated voltages may be broken in the field without harm to the service personnel making and breaking the connection. Additionally, the connector can safely connect high energy fault currents. The connector allows the design to be compatible with existing interchangeability standards. The connector is electrically isolated from the environment prior to the terminator being inserted into the bushing connector to complete a circuit. Additionally, the connector has facility to rapidly close the circuit and also to rapidly open the circuit upon connection and disconnection, thereby minimizing arcing times. The connector also has the capability to block any passage of ionized gasses as the terminator is exiting the connector, thus preventing resultant arcs in the environment from being created due to the ionized gases.
