Laser type demagnetizing and arc-extinguishing lightning arrester

Abstract

The invention relates to a lightning arrester, in particular to a laser type demagnetizing and arc-extinguishing guide lightning arrester. The guide lightning arrester comprises a lightning receiver, a metal lightning arresting tower body and a lightning arrester downlead, wherein an electric spark-isolated metal reflection net is arranged between the lightning receiver and the metal lightning arresting tower body. The guide lightning arrester is characterized in that the lightning receiver is a hollow metal lightning receiver which is at least provided with one lightning receiver needle, a laser generating equipment chamber is arranged between the electric spark-isolated metal reflection net and the metal lightning arresting tower body, the laser generating equipment chamber is communicated with the hollow metal lightning receiver, a solar cell panel is fixedly connected on the outer wall of the laser generating equipment chamber, an electrical storage device and a laser generator are fixedly arranged in the laser generating equipment chamber, the electrical storage device comprises a storage battery, a power supply control switch and remote control equipment, the laser generatoris provided with a laser transmitting terminal, the extension line of the laser transmitting terminal penetrates through the hollow metal lightning receiver, and at least one lightning receiver needle on the hollow metal lightning receiver and the extension line of the laser transmitting terminal converge.

Description

technical field [0001] The invention relates to a lightning rod, in particular to a laser-type degaussing and arc-extinguishing lightning rod. Background technique [0002] Existing lightning rod, has another name called lightning protection rod, is the device that is used to protect buildings etc. from being struck by lightning. Install a metal rod on the top of a tall building (also known as: air receptor or grounding device or guide tower according to the complexity), connect it with a metal plate buried in the ground with a metal wire, and use the tip of the metal rod to discharge, Neutralize the charge carried by the cloud layer and the opposite-sex charge induced by the ground, so as to prevent lightning from directly hitting the protection target. With the advancement of science and technology and people's further understanding of lightning, the existing lightning rods have undergone a lot of improvements, from the original passive lightning to active lightning, whic...

Problems solved by technology

[0004] But, the region defense lightning strike device in the existing active lightning device, especially the laser ionization channel that all exists in the laser type lightning device is too prolonged, and the laser consumes too much in the air (the nearer the distance from the laser transmitter, the laser produced The more obvious the ionization effect is, the worse the effect of ionized air is as the distance increases), that is, the laser that shoots obliquely through the lightning rod to the sky can only form a short ionization channel between the lightning rod and the thunderstorm cloud layer, and the thunderstorm cloud layer needs to be particularly low and Only by entering the ionization channel can it be effectively guided to the lightning rod

Both of the above two laser lightning protection devices have a long laser emission channel. If the ionization channel is to be effectively formed between the lightning rod (guiding tower) and the thunderstorm cloud layer, a high-power laser transmitter is required, which consumes a lot of energy, and it is not guaranteed to pass through. The thunderstorm cloud that breaks away from the laser ionization channel directly above the lightning rod can be effectively intercepted, and real area defense cannot be achieved

Another example is the above two laser lightning protection devices, both let the laser light pass through the lightning rod obliquely to the sky, not only the rest of the ionization channel (between the laser transmitter and the lightning rod) is usually wasted, but also it is very easy for the guided lightning to pass through the ionization channel. Channel hits laser system directly, causing unexpected damage
