Power outage isolation device
View Patent ↗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.
1. A power isolation switch device, comprising:
a first power insulator;
a first conductive member defining a first end;
a first pair of terminals, the first power insulator connected between the first pair of terminals;
a first conductive member connected to a first one of the first pair of terminals and 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 and so as to be disconnected from the second one of the first pair of terminals in an open position;
a first arc chute connected to the second one of the first pair of terminals; and
a first arc contact defining a second end that is swingably connected to the first end of the first conductive member, the first arc contact operably associated with the first conductive member such that the first arc contact is inserted into the first arc chute when the first conductive member is in the closed position and is removed from the first arc chute when the first conductive member is in the open position.
2. The power isolation switch device of claim 1 , further comprising:
a second power insulator;
a second conductive member;
