Abstract

The invention discloses a fire-proof and explosion-proof three-phase power supply lightning protection device, which comprises a circuit board and a lightning protection device housing, wherein the circuit board is provided with a lightning protection circuit; the lightning protection device housing is made of an all-metal material; and the circuit board is arranged in the lightning protection device housing. The lightning protection device housing made of the all-metal material is adopted by the fire-proof and explosion-proof three-phase power supply lightning protection device disclosed by the invention; and the circuit board and components of the power supply lightning protection device are arranged in the metal housing. The metal housing can play fire-proof and explosion-proof roles; the safety when the power supply lightning protection device works is increased; the housing is simple in structural design; and the fire-proof and explosion-proof three-phase power supply lightning protection device is relatively convenient to install and maintain.

Description

technical field [0001] The invention relates to the technical field of lightning protectors, in particular to a fireproof and explosion-proof three-phase power supply lightning protector. Background technique [0002] Surge protector, also called surge protector, is an electronic device that provides safety protection for various electronic equipment, instruments, and communication lines. When the electrical circuit or communication line suddenly generates a peak current or voltage due to external interference, the surge protector can conduct the shunt in a very short time, so as to avoid the damage of the surge to other equipment in the circuit. [0003] Among them, the power surge protector is mainly for the surge protection selected by the power system, and is used to prevent the equipment from being struck by lightning. Avoid a series of damage caused by lightning strikes such as damage to equipment or components, casualties, interference or loss of transmitted or store...
