Description

Technical Field

[0001] The utility model relates to the technical field of electrical cabinets, in particular to a lightning protection type electrical cabinet. Background Art

[0002] Electrical cabinets are made of steel and are used to protect components. They are generally made of hot-rolled and cold-rolled steel. Cold-rolled steel is softer than hot-rolled steel, making it more suitable for electrical cabinet construction. Electrical cabinets are widely used in the chemical industry, environmental protection, power systems, metallurgy, industry, nuclear power, fire safety monitoring, transportation, and other industries.

[0003] In the prior art, when designing lightning protection for an electrical cabinet, a lightning arrester is generally installed on the electrical cabinet and connected to a grounding device through a metal wire to achieve lightning protection operation. However, when using metal wires to connect the lightning arrester and the grounding device, the metal wires are mostly exposed to the external environment, resulting in the metal wires being easily corroded by rainwater when the electrical cabinet is in the external environment, thereby affecting the lightning protection effect of the electrical cabinet and shortening its service life.
