摘要： A switchgear system includes a switchgear frame having an interior compartment and front opening and containing therein at least one electrical switchgear component. A truck carries an electrical component and is supported for movement on the switchgear frame. A drive mechanism connects the truck and is configured to rack in the truck into an electrically connected position with the at least one electrical switchgear component, rack out the truck from the electrically connected position into an electrically disconnected position, and rotate the truck upward from its disconnected position into a rotated position to allow operator access through the front opening to the at least one electrical component.

摘要： Power receiving/distributing equipment is composed of a switchgear incorporated for each major electric path section, wherein, when arc fault occurs on an electric path to which a circuit breaker is connected, a high-speed closing device closes to detour arc current so as to flow to a ground conductor, thereby eliminating arc at a fault electric path portion. The high-speed closing device is connected to one pole or both poles of a breaking portion of the circuit breaker, and is incorporated into an insulating support member on a corresponding pole electric path so as to be able to be drawn as a whole.

摘要： An operating modes selector is for an earthing switch that includes power contacts and a motor for moving the power contacts. The selector includes a plurality of positions corresponding respectively to various operating modes of the earthing switch, and includes cams whose positions are defined by the selector position. The selector contains a first cam which pulls a first locking organ designed to mechanically block the motor of the earthing switch when the selector is in a position corresponding to a locked closed mode wherein the earthing switch is closed.
