Abstract
A device may include a metal-oxide varistor (MOV), wherein the MOV increases in temperature as a voltage applied across the MOV exceeds a rated voltage. The device may include a first conductor contacting the MOV and a second conductor contacting the MOV. The second conductor may be configured to disconnect from the MOV when the MOV reaches a threshold temperature. The device may include an enclosure to surround the MOV, the first conductor, and the second conductor, wherein the enclosure includes a non-conductive fluid to suppress arcing.
Claims22
A device, comprising:
- a metal-oxide varistor (MOV), wherein the MOV increases in temperature as a voltage applied across the MOV exceeds a threshold voltage;
- a first conductor electrically coupled to the MOV;
- a second conductor electrically coupled to the MOV, wherein the second conductor is configured to electrically decouple from the MOV when the MOV reaches a threshold temperature;
- and
- an enclosure to surround the MOV, the first conductor, and the second conductor, wherein the enclosure includes a non-conductive fluid to suppress arcing.
A device, comprising:
- a voltage sensitive element for shunting current when a voltage applied across the voltage sensitive element exceeds a threshold voltage;
- a first conductor electrically coupled to the voltage sensitive element;
- a second conductor electrically coupled to the voltage sensitive element, wherein the second conductor is configured to electrically decouple from the voltage sensitive element when the voltage applied across the voltage sensitive element exceeds the threshold voltage;
- and
- an enclosure to surround the voltage sensitive element, the first conductor, and the second conductor, wherein the enclosure includes a non-conductive fluid to suppress arcing.
