Deflection sync compression arc extinguishing and lightning protection device having zigzag-shaped arc extinguishing path at the skirt edge

Abstract

The invention discloses a zigzagging synchronous compression arc extinguishing lightning protection device with a zigzag arc extinguishing path on the skirt, comprising a lightning protector main body and an arc striking electrode, and a skirt is arranged on the outer surface of the lightning protector main body; wherein: the skirt There is an arc-extinguishing path II composed of several arc-extinguishing tubes II arranged along the circumference; The end of the arc extinguishing tube Ⅰ is electrically connected, and the end of the last arc extinguishing tube Ⅱ is electrically connected to the head end of the arc extinguishing tube Ⅰ in the main body of the arrester below the skirt and closest to the skirt; two adjacent extinguishing tubes The ends of the arc tube II are directly connected to each other or connected through the connector II; there is an air outlet channel II at the junction of two adjacent arc tube II, and the air outlet channel II extends to the outer edge of the skirt. The surface, that is, the outer surface of the skirt is provided with the airflow outlet II. The invention has the advantages of simple structure, reasonable design, stronger arc extinguishing ability and stable and reliable operation.

Description

technical field [0001] The invention relates to a lightning protection device for a power transmission line, in particular to a zigzag synchronous compression arc extinguishing lightning protection device with a zigzag arc extinguishing path on the skirt. 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...

Problems solved by technology

[0008] Although the above patents have played a very good role in lightning protection, there are still some shortcomings. There is only the vertical blowing arc extinguishing method. When the arc is strong, the arc is not easy to blow out.
