Anti-thunder lightning arrester with automatic lifting function

Abstract

The invention discloses an anti-thunder lightning arrester with an automatic lifting function, comprising an insulating base, wherein an annular ring body is arranged on the insulating base; an opening is formed on the top of the annular ring body; a plurality of metal sheets are arranged on the outer side of the annular ring body; a groove is formed between the metal sheets; and an insulating sheet is disposed on the groove. The invention provides an anti-thunder lightning arrester with an automatic lifting function, the structure is set ingeniously, and a relatively uniform layered electricfield environment is utilized to repel the thundercloud electric field so as to achieve a significant reduction in the probability of lightning strikes. When the electric field generated by an inducedcharge layer cannot repel the excessive thundercloud electric field, the thundercloud electric field is attracted by a lightning rod, discharges and releases a large amount of energy through a discharge tungsten wire, and flows to the earth through an earth wire; moreover, when the weather is fine, the insulating base is put away to avoid affecting the space at the top of the floor; and when lightning weather occurs, the insulating base is raised for anti-thunder lightning protection.

Description

technical field [0001] The invention relates to the technical field of lightning protection equipment, in particular to a lightning protection and lightning protection device with an automatic lifting function. Background technique [0002] The modern lightning rod was invented by American scientist Franklin. Franklin believed that lightning was an electrical discharge. To prove this, on a thunderstorm day in July 1752, at the risk of being struck by lightning, he flew a kite tied with a long metal wire into a thunderstorm cloud, and tied a bunch of silver keys to the end of the metal wire. When the lightning struck, Franklin approached the key, and a string of electric sparks burst out from the key. There is also numbness in the hands. Fortunately, the lightning passed down this time was relatively weak, and Franklin was not injured. [0003] After successfully carrying out the kite experiment to capture lightning, when Franklin was studying the consistency of lightning...

AI Technical Summary

Problems solved by technology

The invention of the lightning rod was the first technical achievement with significant application value in the early electrical research. The traditional lightning rod was installed at the highest point of the building. When lightning occurs, the highest point and the thundercloud form an extremely unevenly distributed electric field. environment, the air between the thundercloud and the lightning rod is easily broken down, and the lightning current can easily discharge lightning energy to the earth through the lightning rod

In fact, this kind of lightning protection method that discharges lightning energy by guiding the lightning itself is more likely to cause direct lightning strikes.

[0004] In addition, the traditional lightning protection device has a fixed form, which affects the utilization of the space at the top of the floor when the weather is fine.
