Zigzag sync compression arc extinction and lightning protection device of parallelly arranged arc extinction channels

Abstract

The invention discloses a zigzag sync compression arc extinction and lightning protection device of parallelly arranged arc extinction channels. The zigzag sync compression arc extinction and lightning protection device comprises a lightning protection device body (1) and an arc striking electrode (3), wherein an arc extinction path composed of the several arc extinction channels parallelly arranged from top to bottom is arranged inside the lightning protection device body; arc extinction pipes (5) are placed in all the arc extinction channels, wherein the head end of the arc extinction pipe in the first arc extinction channel is electrically connected with the arc striking electrode (3), the tail end of the arc extinction pipe in the last arc extinction channel is electrically connected with a connecting hardware fitting (4), and the ends of every two adjacent arc extinction pipes are connected through a three-way pipe (6) and two T-shaped arc guide pipes (9); the transverse ends andthe longitudinal ends of the T-shaped arc guide pipes (9) are embedded in the arc extinction pipes (5) and the three-way pipes (6) respectively. The zigzag sync compression arc extinction and lightning protection device is simple in structure, reasonable in design, higher in arc extinction capability and stable and reliable in work.

Description

Technical field [0001] The invention relates to a lightning protection device for power transmission lines, in particular to a zigzag synchronous compression arc extinguishing lightning protection device with parallel arc extinguishing channels. 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 yet been controlled. But we can analyze the frequent accidents to find the law of lightning strikes and strengthen prevention. For example, poles and towers on high mountains or peaks, power transmission lines near ponds or reservoirs, poles that cross mountains or rivers and lakes, poles and towers installed on high grounding resistance, rock tower foundations, and transmission lines are all vulnerable to lightning damage Focus. [0003] Lightning strikes can bring different forms of damage and destruction to powe...

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.
