Problems solved by technology

[0005] However, if the lightning protection module is in the conduction state for a long time, it will generate a lot of heat. When the heat accumulates to a certain extent, it will burn and catch fire, which will ignite the power supply part and cause losses.

Abstract

The invention discloses a power lightning protection box. The power lightning protection box comprises a casing (1), wherein a baffle (2) is arranged in the casing (1) to separate the internal space of the casing (1) into a power part (1a) and a lightning protection part (1b); a power line (3) is arranged in the power part (1a); a lightning protection module (4) is arranged in the lightning protection part (1b); one end of the lightning protection module (4) is electrically connected with the power line (3); and the other end of the lightning protection module (4) is grounded. After the interior of the power lightning protection box is divided into the lightning protection part and the power part through the baffle, the power line in the power part can not be ignited, even if the lightning protection module in the lightning protection part is overheated and on fire.

Description

technical field [0001] The invention relates to a lightning protection box for a power supply. Background technique [0002] Usually the so-called lightning strike refers to the rapid discharge between a part of the charged cloud layer and another part of the cloud layer with different charges, or between the charged cloud layer and the earth. This rapid discharge produces an intense flash of light accompanied by a loud sound. Of course, the discharge between the clouds is mainly harmful to the aircraft, and has no great impact on the buildings, people and animals on the ground. However, the discharge of the cloud layer to the earth is very harmful to buildings, electrical and electronic equipment, and people and animals. [0003] Due to the effect of electrostatic induction, the charged cloud layer causes a certain area of ​​the ground to be charged with a different kind of charge. When the direct lightning strike occurs, the charge on the cloud layer disappears quickly, ...
