Thunder-lightening induced solid-phase arc-extinguishing lightning arrester

Abstract

The invention discloses a thunder-lightening induced solid-phase arc-extinguishing lightning arrester. The thunder-lightening induced solid-phase arc-extinguishing lightning arrester mainly consists of a lightning arrester shell, an arc-extinguishing rotary table, an electric conduction metal plate, a starting rod, a clamping rod, an induction coil, an arc-extinguishing barrel and a counting pointer; the arc-extinguishing rotary table is arranged inside the lightning arrester shell, and a flat spiral spring for pushing the arc-extinguishing rotary table to rotate is arranged at the central position of the arc-extinguishing rotary table; the electric conduction metal plate is arranged at the upper part of the arc-extinguishing rotary table; the arc-extinguishing rotary table is provided with a plurality of arc-extinguishing gas pills in the peripheral direction; one side of each arc-extinguishing gas pill is provided with a trigger electrode and a groove respectively, one end of each trigger electrode is connected with one of trigger ends of the corresponding arc-extinguishing gas pill through a lead, and the other ends of the trigger electrodes extend out of the edge of the arc-extinguishing rotary table; and the other of the trigger ends of the corresponding arc-extinguishing gas pill is connected with the electric conduction metal plate through a lead. The thunder-lightening induced solid-phase arc-extinguishing lightning arrester is simple in structure, reasonable in design, high in arc-extinguishing ability and stable and reliable to work, and the arc-extinguishing gas pills are changed quickly and conveniently.

Description

technical field [0001] The invention relates to a lightning protection device for a power transmission line, in particular to a lightning-induced solid-phase arc-extinguishing lightning protection device. Background technique [0002] Lightning is an important factor affecting the safety of transmission lines. It has long occupied the first place in line fault tripping. It is a natural process of atmospheric activity and has not been controlled so far. However, we can analyze the frequent accidents to find the law of lightning strikes and strengthen prevention. For example, towers on high mountains or peaks, transmission lines near ponds or reservoirs, towers crossing mountains or rivers and lakes, and towers installed on high grounding resistance, rocky tower foundations and transmission lines are all vulnerable to lightning damage. focus. [0003] Lightning strikes will bring different forms of damage and damage to power facilities. Thundercloud discharge will cause ligh...

Problems solved by technology

[0009] Although the above patents have played a very good role in lightning protection, there are still some deficiencies, such as only one electrode is equipped with an arc extinguishing device, and when the arc is started on the other electrode, the arc starting point cannot be cut off and extinguished. Arc and discharge counters are large in size, difficult to install in some specific occasions, weak in anti-interference ability, easy to generate wrong counts, data cannot be stored, manual records are required, and a lot of labor is wasted
