Modular "Y"-type enclosure elements for gas insulated substations

Abstract

A modular "Y"-type enclosure element particularly adapted for gas insulated substations. The enclosure element comprises a first generally "Y"-shaped enclosure element having a circuit protective device, such as a circuit breaker or conductor, disposed therein for controlling the flow of current through the enclosure element. A flanged opening is attached to each leg of the enclosure element for electrical and mechanical attachment to another enclosure element. A second generally "Y"-shaped enclosure having a circuit control device, such as a ground switch, disposed within the enclosure element also for controlling the flow of current through said enclosure element. A flanged opening is again attached to each leg of said second enclosure element for electrical and mechanical attachment to first said enclosure element.
