Abstract

The invention discloses a high temperature and high voltage resistance switch cabinet, and relates to the technical field of switch cabinets. The high temperature and high voltage resistance switch cabinet comprises a box, a protective coating layer is arranged on the surface of the box and comprises, by weight, 15-23 parts of resin, 6-9 parts of styrene-acrylonitrile-butadiene terpolymer, 5-10 parts of polyacrylamide, 2-5 parts of UV (ultraviolet) anti-aging particles, 4-6 parts of hollow ceramic micro-beads, 7-9 parts of ceramic clay, 5-7 parts of silicon carbide, 2-4 parts of mullite and 1-2 parts of zinc iron phosphate. The switch cabinet not only has a certain high-temperature resistance, but also has strong light stability.

Description

technical field [0001] The invention relates to the technical field of switch cabinets, in particular to a high temperature and high pressure resistant switch cabinet. Background technique [0002] High and low voltage switchgear is an important equipment used in the power supply and distribution system. It is the main component of the power transmission and distribution industry. It is widely used in different places, such as high-rise buildings, residential quarters, industrial and mining enterprises, construction sites and other places. The use environment Harsh, the existing switchgear is used in a high temperature and high pressure environment, which may lead to a high temperature on the surface of the box. At present, the surface of the box may crack, swell, fall off, etc. when using ordinary paint at high temperature, which greatly reduces the service life of the switchgear. Contents of the invention [0003] The technical problem to be solved by the invention is t...
