Novel distribution line arc extinguishing lightning protection gap device

Abstract

The invention provides a novel distribution line arc extinguishing lightning protection gap device comprising an insulator chain; a grounding side electrode is arranged above the insulator chain through an upper connecting armour clamp; a line side electrode is arranged below the insulator chain through a lower connecting armour clamp; a lightning protection gap is formed between the grounding side electrode and the line side electrode; the grounding side electrode is provided with an inductor; an arc extinguishing device is fixed on the lower connecting armour clamp, and comprises a base plate; a cylinder support is arranged on the base plate, and fixedly provided with an oblique insulation cylinder; a plurality of gas generators are arranged in the cylinder support; a gap is formed between the insulation cylinder bottom and the base plate top surface; the insulation cylinder side on the base plate is provided with a push device; the insulation cylinder outer side is also provided with a trigger mechanism. The novel distribution line arc extinguishing lightning protection gap device can set the plurality of gas generators in one time, and can ensure the gas generators to be stably triggered in order, thus improving the arc extinguishing lightning protection gap work stability, and reducing maintenance cost.

Description

technical field [0001] The invention mainly relates to a gas arc extinguishing and lightning protection device, in particular to a novel arc extinguishing and lightning protection gap device for power distribution lines. Background technique [0002] The lightning protection of transmission lines has always been an important part of the lightning protection work of the power sector, and lightning faults are also one of the important factors affecting the safety of the power grid. At present, the gas arc extinguishing lightning protection device is widely used because of its good arc extinguishing effect. However, the traditional gas arc extinguishing and lightning protection device generally adopts the method of emitting gas pills to generate impact airflow to act on the gap arc to extinguish the arc. In the actual use process, there will be the following problems: the replacement of gas pills is extremely inconvenient, and the parts need to be disassembled. There are many ...

However, the traditional gas arc extinguishing and lightning protection device generally adopts the method of emitting gas pills to generate impact airflow to act on the gap arc to extinguish the arc. In the actual use process, there will be the following problems: the replacement of gas pills is extremely inconvenient, and the parts need to be disassembled. There are many components; the operation of the gas generating device is unstable, and it cannot be guaranteed to be triggered effectively in a timely manner; the number of gas generating devices is small, and the use time after one-time installation in places where lightning occurs frequently is short, the maintenance cycle is short, the cost is high, and multiple gas The sequence of connection between the generating devices cannot be done well, that is, after the function of the previous gas generating device, the next gas generating device cannot enter the station to be triggered in a timely and effective manner
