Abstract
A quick open and close disconnect switch suitable for use in EHV and UHV systems is disclosed. In addition to a conventional main moving contact and a conventional mechanism for operating it, a preferably much smaller, lighter auxiliary moving contact is provided. The main moving contact is moved away from (or toward) the stationary contacts to open (or close) the switch. While this is happening, the auxiliary moving contact is retained by means of a latch arrangement in its position engaged with (or remote from) the stationary contact. When the main moving contact has traversed a predetermined portion of its path, the auxiliary moving contact is released and is moved suddenly, with great speed, to its open (or close) position. The motive power for the auxiliary moving contact is preferably provided by a power spring which is compressed by the movement of the main contact.
