摘要： A medium-voltage switchgear system includes a three-phase circuit breaker having first, second and third single-phase vacuum interrupters connected between respective first, second and third single-phase inputs and first, second and third single-phase outputs. Magnetic actuators are connected to first, second and third single-phase vacuum interrupters, which are configured to receive an interrupt signal and in response, actuate the respective vacuum interrupter connected thereto into an open circuit condition. A controller circuit is connected to each of the first, second and third magnetic actuators and generates an interrupt signal in response to a detected single-phase overcurrent or fault on a single-phase circuit and interrupt that single-phase circuit on which the single-phase overcurrent or fault occurred and maintain power on the remaining two single-phase circuits over which a single-phase overcurrent or fault was not detected.

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： Cradle-assist assemblies attached to the breaker cradle housing and/or base or residing at least partially in the breaker cradle housing and/or base include at least one actuator configured to laterally translate the at least one right and the at least one left lock members from the extended lock position to the retracted unlocked position in response to input from a user. The at least one actuator and/or transverse member(s) can be held in a defined position so that the lock members of the cradle can be locked in the respective retracted or extended positions until the cradle assist (internal) lock is manually or automatically released.

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.
