Motorized vacuum isolation switch

摘要

Methods, systems, devices for a motorized isolation switch including a switch enclosure with a set of fixed insulated floating input line connectors and output load connectors movably fixed to the rear panel, a removable contactor bucket insertable into the isolation switch enclosure with mating movable insulated line terminals and load terminals and a set of insulated circuit interrupters, a motorized rack and pinion assembly connected to a base of the switch enclosure, coupled for moving a contactor pan connectable to the contactor bucket along a stationary rack gear along the base of the switch enclosure between and switch open position and a switch closed position, an insulating grounding block with ground connectors, the contactor bucket with corresponding movable ground terminals to mate with the insulated ground connectors in the switch open position, and ancillary controls for communicating with remotely located controls to electrically control the operation.

主权项

1. A contactor bucket for installation into a motorized stationary isolation switch enclosure comprising:
a contactor bucket frame; a rear panel with one or more insulated source terminals and one or more insulated load terminals, each source and load terminal pair corresponding to one phase of an electrical power source; a front panel with one or more grounding terminals, each one corresponding to one phase of the power source; an insulated circuit interrupter for each phase with an input terminal and output terminal and switchable contacts enclosed therein, each one or more insulated source terminals connected to a corresponding circuit interrupter input terminal and each one of the insulated load terminals connected to a corresponding circuit interrupter output terminal and to a corresponding one of the grounding terminals; a stuck bottle indicator panel assembly with an indicator corresponding to each one of the insulated circuit interrupters to show an energized state of each corresponding circuit interrupter internal switchable contacts, the indicator panel attached above the one or more grounding terminals; and a control interface for controlling a position of the one or more insulated circuit interrupter enclosed switchable contacts.
