Abstract
Disclosed is an operating mechanism for high voltage switches that incorporates certain uncoupling, drawout, and interlocking features. The operating mechanism is mounted on rollers which roll in tracks on upper and lower mounting brackets attached to the side of the equipment enclosure also containing the high voltage switches. A latching mechanism secures the switch operating mechanism in its test and maintenance positions. By operating a drawout latch lever which is located on the control panel of the operating mechanism on the outside of the equipment enclosure, the latching mechanism can release the switch operating mechanism from the test or maintenance positions permitting it to be reinserted or withdrawn farther. The drawout latch lever on the control panel of the switch operating mechanism also indicates when the switch operating mechanism is in the test or maintenance positions. The coupled position of the switch operating mechanism is sensed electrically by a position indicating switch. A locking mechanism prevents any movement of the high voltage switch while the door of the equipment enclosure is in a predetermined position or while the switch operating mechanism is un…
