Problems solved by technology

However, it does not have the ability to actively extinguish the arc, and cannot automatically extinguish the power frequency freewheeling arc caused by the breakdown of the air gap. Only when it is used in conjunction with the automatic reclosing device can a better lightning protection effect be obtained
However, due to the need to wait for the circuit breaker to operate, it takes a long time to extinguish the arc on the series gap. Every time the overvoltage on the line is released to the ground, it may cause the metal fittings to be burned by the arc, and even burn the wire in severe cases.

Abstract

The invention relates to a lightning arrester. The lighting arrester comprises a main body and a connecting assembly, the main body is fixedly connected with the connecting assembly, the main body comprises steel electrodes and discharge chambers, the steel electrodes and the discharge chambers are arranged at intervals, the connecting assembly comprises long clamping pieces and short clamping pieces, and the long clamping pieces and the short clamping pieces are connected through bolts. The lighting arrester can be directly installed on an overhead distribution line, does not need to be grounded, can effectively discharge an overvoltage, and achieves the active arc extinguishing effect.

Description

technical field [0001] The invention relates to the technical field of lightning protection, in particular to a lightning arrester. Background technique [0002] Installing surge arresters with series gaps on overhead distribution lines can effectively discharge overvoltage and protect insulators from burning by discharge arcs when the lines are struck by lightning. Ordinary surge arresters with series gaps can effectively absorb the overvoltage on the line, break down the air gap, and guide the overvoltage to the ground. However, it does not have the ability to actively extinguish the arc, and cannot automatically extinguish the power-frequency freewheeling arc caused by the breakdown of the air gap. Only when it is used in conjunction with an automatic reclosing device can a better lightning protection effect be obtained. However, due to the need to wait for the circuit breaker to operate, it takes a long time to extinguish the arc on the series gap. Every time the overvo...
