Problems solved by technology

[0011] Although the above patents have played a very good role in lightning protection, there are still some deficiencies, such as, for multiple lightning, the arc extinguishing effect is not obvious, there is a re-ignition phenomenon, etc., and the volume of the discharge counter is large, which is difficult to install in some In specific occasions, the anti-interference ability is weak, it is easy to generate wrong counts, the data cannot be stored, manual records are required, and a lot of labor is wasted; in addition

Abstract

The invention discloses an arc extinguishing lightning protection device capable of excluding bomb jamming. The device comprises a lightning protection device body and an arc striking electrode. The lightning protection device body is fixedly arranged on a cross arm or one end of an insulator string through a connection fitting. A left bomb storing bin and a right bomb storing bin are arranged in the lightning protection device body. The device further comprises a double pointer digital counter which is fixedly arranged on the outer surface of the lightning protection device body. A counting press point I and a counting press point II are respectively arranged on a preliminary track I of the left bomb storing bin and a preliminary track II of the right bomb storing bin. Two elastic rubber blocks are respectively arranged above a pill trigger position I and a pill trigger position II. A face change switch which is connected in series with the connection loop of a trigger electrode II and an induction coil is arranged on the preliminary track II of the right bomb storing bin. The arc extinguishing lightning protection device provided by the invention has the advantages of simple structure, reasonable design, strong arc extinguishing ability, stable and reliable work and easy post maintenance and replacement, and is capable of counting.

Description

technical field [0001] The invention relates to a lightning protection device for a power transmission line, in particular to an arc extinguishing lightning protection device capable of eliminating stuck bullets. 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 ca...
