Abstract

The invention discloses an insulating shell of a switch cabinet. The insulating shell of the switch cabinet is prepared from the following raw materials in parts by weight: 25 to 28 parts of glass fiber, 6 to 14 parts of silicon dioxide, 9 to 12 parts of fiber cotton, 20 to 24 parts of polycarbonate resin, 7 to 13 parts of polyurethane, 2 to 8 parts of polypropylene, 16 to 20 parts of poly(1-butene), 2 to 4 parts of boric oxide, 7 to 8 parts of calcium carbonate, 8 to 10 parts of barium sulfate, 6 to 14 parts of aromatic polyamide fiber, 2 to 8 parts of molybdenum disulfide, 4 to 8 parts of dibutyl phthalate, 13 to 15 parts of diisobutyl phthalate, 7 to 9 parts of sodium citrate, 3 to 8 parts of zirconium tetrafluoride, 11 to 14 parts of ethyl acetate, 6 to 12 parts of butyl methacrylate and 18 to 20 parts of N-phenyl-beta-naphthylamine. The insulating shell of the switch cabinet has high structure strength, good insulating effect and good anti-ageing effect.

Description

technical field [0001] The invention relates to an insulating shell of a switch cabinet. Background technique [0002] The switch cabinet is a kind of electrical equipment. The outside line of the switch cabinet first enters the main control switch in the cabinet, and then enters the sub-control switch. Each branch is set according to its needs. Such as instruments, automatic controls, motor magnetic switches, various AC contactors, etc., some also have high-voltage room and low-voltage room switch cabinets, high-voltage busbars, such as power plants, etc. load shedding. The main function of the switchgear is to open and close, control and protect electrical equipment during the process of power generation, transmission, distribution and power conversion in the power system. The components in the switch cabinet are mainly composed of circuit breakers, disconnectors, load switches, operating mechanisms, transformers and various protection devices. There are many classifica...
