Abstract
A modular vault type load break switch wherein the switching assembly is carried within an oil filled vault such that the operation of the switching mechanism is independent of the vault structure. The switching contact mechanism employs a positive actuator which is energized by the operator and contact movement effected by a remotely controlled mechanism independent of operator contact.
Claims10
A modular vault-type load-break switch comprising
- stationary electrical contact means for coupling to an electrical conductor to form an electrical circuit upon the closing of movable electrical contact means thereinto,
- movable electrical contact means for coupling to an electrical conductor to form an electrical circuit upon closing into said stationary electrical contact means,
- drive means operatively connected to said movable electrical contact means for applying a driving force thereto to close said movable electrical contact means into said stationary electrical contact means and to open said movable electrical contact means from engagement with said stationary electrical contact means,
- control means operatively connected to said drive means for actuating said drive means to apply the driving force to said movable electrical contact means to effect movement of said movable electrical contact means in the direction in which said drive means applies the driving force, and
- latch means for preventing the movement of said movable electrical contact means in a direction opposed to the movement effected by the driving force applied by said drive means thereby providing a positive closing of said movable electrical contact means into said stationary electrical contact means and a positive opening of said movable electrical contact means from engagement with said stationary electrical contact means.

A pre-assembled modular vault-type loadbreak switch for use in a below grade tank comprising
- a frame having spaced vertically extending supports adapted for insertion into a tank for containing said frame,
- stationary electrical contact means supported from said frame between the spaced vertically extending supports for coupling to an electrical conductor to form an electrical circuit upon the closing of movable electrical contact means thereinto,
- movable electrical contact means supported from said frame between the spaced vertically extending supports adjacent said stationary electrical contact means in operable contact therewith for coupling to an electrical conductor to form an electrical circuit upon closing into said stationary electrical contact means,
- rotatable drive means supported by one of said supports and operatively connected to said movable electrical contact means and actuable for applying a driving force to close said movable electrical contact means into said stationary electrical contact means and to open said movable electrical contact means from engagement with said stationary electrical contact means,
- control means carried by one of said supports and operatively connected to said drive means for controlling the actuation of said drive to apply the drive force to said movable electrical contact means to effect movement thereof in the direction in which the driving force is applied, and
- latch means for preventing the movement of said movable electrical contact means in a direction opposed to the movement effected by said drive means thereby providing a positive closing of said movable electrical contact means into said stationary electrical contact means and a positive opening of said movable electrical contact means from engagement with said stationary electrical contact means.
