Abstract
This disclosure relates generally to power isolation switch devices. In one embodiment, a power isolation switch device has a power insulator, an arc breaker, and a switch. The power insulator and the switch are connected in parallel. The arc contact is operably associated with the switch such that the arc contact is removed from the arc chute as the switch is opened and is inserted to contact the arc chute when the switch is closed. In this manner, the power isolation switch device does not need an interrupter and can be provided so as to be less bulky.
Claims18
A power isolation switch device, comprising:
- a first power insulator;
- a first switch, comprising:
- a first conductive member defining a first end;
- a first pair of terminals, wherein the first power insulator is connected between the first pair of terminals;
- wherein the first conductive member is connected to a first one of the first pair of terminals and is swingably attached to the first one of the first pair of terminals so as to connect to a second one of the first pair of terminals in a closed position;
- a first arc breaker comprising a first arc chute and a first arc contact, wherein the first arc contact defines a second end that is swingably attached to the first end of the conductive member;
- wherein the first power insulator and the first switch are connected in parallel;
- wherein the first arc contact is operably associated with the first switch such that the first arc contact is removed from the first arc chute as the first switch is opened and is inserted to contact the first arc chute when the first switch is closed such that the second end of the first arc contact is configured to swing about the first end of the conductive member to remain in the arc chute when the conductive member is being opened until the conductive member reaches a minimum angle whereby the first arc contact is removed from the arc chute.
