Abstract

The invention discloses a skirt having an arc extinguishing path, which is disposed at the outer surface of a lightning protection device. The internal part of the skirt is provided with an arc extinguishing path I formed through arranging a plurality of arc extinguishing pipes along the circumferential direction, and the arc extinguishing path I is in series connection with an arc extinguishing path II of the lightning protection device. The end parts of two adjacent arc extinguishing pipes in the arc extinguishing path I are directly connected to each other in a contacting manner or are connected to each other through a connecting piece. A connecting part of two adjacent arc extinguishing pipes close to the outer edge of the skirt is provided with an airflow spraying channel. The airflowspraying channel extends to the outer surface of the skirt, which means that the outer surface of the skirt is provided with an airflow spraying outlet. The invention is advantageous in the structureis simple, design is reasonable, arc extinguishing capability is strong, and work is stable and reliable.

Description

technical field [0001] The invention relates to a lightning protection device for a power transmission line, in particular to a skirt provided with an arc-extinguishing path. 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 lightning overvoltage in the power...
