Abstract

The invention belongs to the technical field of insulation of electrical equipment, and particularly relates to an insulating protective agent for an electric power switch cabinet and an application of the insulating protective agent. The insulating protective agent for the electric power switch cabinet is prepared from components in parts by weight as follows: 30-35 parts of asbestos powder, 15-25 parts of porcelain clay, 10-15 parts of modified glycerol phthalate resin, 10-15 parts of phenolic resin, 5-10 parts of silicone oil, 5-8 parts of an inorganic flame retardant and 10-13 parts of inorganic fiber. The insulating protective agent for the electric power switch cabinet can form a thin film with thickness of 20-35 mu m, protects circuits against damage under the severe condition and has good insulating and moisture-resisting performance, meanwhile, the service life of the electric power switch cabinet is prolonged, safety stability and reliability in use are ensured, and the insulating protective agent is not prone to falling off and has high stability.

Description

technical field [0001] The invention belongs to the technical field of electrical equipment insulation, and in particular relates to an insulating protective agent for an electrical switch cabinet and an application thereof. Background technique [0002] With the gradual development of the social economy and the further improvement of people's living standards, the electricity demand of the majority of users has risen rapidly, and a large number of high-voltage power equipment has been put into use. However, in the actual operation of the equipment, due to various reasons, the user's Insulation faults often occur in high voltage switchgear. Among them, the high-voltage switchgear is the most used switchgear. Because there are different degrees of problems in design, manufacture, installation and operation and maintenance, the accident rate is relatively high. In various types of switchgear accidents, insulation accidents mostly occur at voltage levels of 10kV and above, an...
