Abstract

The invention discloses a grounding device with spark thorns. The grounding device comprises a horizontal grounding body, the horizontal grounding body comprises a grounding body main body and a plurality of grounding body branches connected with the grounding body main body; and a plurality of spark thorns are arranged on each grounding body branch at equal intervals, and an included angle is formed between adjacent spark thorns. According to the invention, the spark thorns are designed at equal intervals and form a certain included angle with each other, so that the shielding effect betweenthe spark thorns can be weakened.

Description

technical field [0001] The disclosure belongs to the technical field of lightning protection and grounding of power systems, and in particular relates to a grounding device with spark spikes. Background technique [0002] Lightning strike is an important threat to the safe and reliable operation of power systems. my country's power grid fault statistics show that in areas with a high trip rate of transmission lines, the number of trips caused by lightning strikes on towers or transmission lines accounts for about 40-60% of the total number of trips on transmission lines. Improving the lightning resistance level of transmission lines and reducing the lightning trip rate are of great significance to the safe and stable operation of power systems. Lightning protection grounding is a key measure to reduce the lightning tripping rate of transmission lines, and reducing the grounding resistance of the grounding device is crucial to lightning protection. [0003] For a long time,...
