Abstract

The invention provides a lightning arresting method and device with function of inhibiting lightning stroke current intensity and relates to a lightning arresting method and device with function of inhibiting lightning stroke current intensity which are applied to direct lightning flash protection of buildings. The device comprises a lightning arrester, at least one high-frequency impulse transformer and a grounded device, wherein the high-frequency impulse transformer comprises a primary coil, a magnetic core and a secondary short circuit coil; the primary coil and the secondary short circuit coil form electromagnetic coupling through the magnetic core; a loop is formed by the secondary short circuit coil; and when more than two high-frequency impulse transformers are arranged, the primary coils of the high-frequency impulse transformers are connected in series with a loop formed by the lightning arrester and the grounded device. When lightning stroke current passes through the lightning arrester, the primary coils of the high-frequency impulse transformers and a lightning stroke release loop, energy in the primary coils is coupled to the secondary short circuit coils through the magnetic cores of the high-frequency impulse transformers and is consumed by internal resistors of the secondary short circuit coils, and thus the size of the lightning stroke current in the lightning stroke release loop is limited and the purpose of inhibiting the lightning stroke current is achieved.

Description

technical field [0001] The present invention relates to a lightning receiving method with suppression of lightning current intensity and a device thereof, which are applied to protection against direct lightning strikes such as buildings, and more specifically relates to a method and a device thereof capable of greatly reducing lightning current intensity. It is widely used in the protection of lightning strikes in buildings, wind power impellers, solar power, ships, and communication stations. Background technique [0002] At present, there is no device for effectively suppressing the current intensity of lightning strikes in lightning protection devices (commonly known as lightning rods) and lightning energy discharge circuits used in buildings and other lightning protection. The amount of charge in the charged cloud layer, the level of voltage, the impedance of the discharge circuit and the grounding resistance, due to the small impedance and grounding resistance of the l...
