A surge arrester disconnector

Abstract

This utility model discloses a surge arrester disconnector, including a disconnector housing, a high-voltage electrode disposed inside the disconnector housing, and a grounding electrode installed at the bottom of the disconnector housing. An electronic resistor is disposed inside the disconnector housing, and a second spring is sleeved on the outside of the electronic resistor. A thermal nail gun is installed at the bottom of the electronic resistor. An indicator shell is slidably mounted on the outside of the disconnector housing. Connecting rods are symmetrically arranged on the outside of the high-voltage electrode. Low-temperature solder is provided between the two connecting rods and the indicator shell. Multiple vertical rods are integrally formed on the inner side of the indicator shell, and a first spring is sleeved on the outside of the vertical rods. This utility model, through the use of low-temperature solder, the first spring, the vertical rods, and the connecting rods, ensures that when the surge arrester malfunctions or ages, the indicator shell will automatically separate from the disconnector housing, thus exposing the red outer shell of the disconnector housing for indication, resulting in a very clear indication effect.
