Rapid repair process for external insulation of water immersion power secondary equipment

Abstract

The invention discloses a rapid repair process for external insulation of water immersion power secondary equipment. Firstly, dirt such as silt inside and outside electric power secondary equipment are washed by using deionized water, and water is blown dry at normal temperature by using a fan after washing; a high-insulation cleaning agent is used for spraying and washing the electric power secondary equipment, and water remaining in the electric power secondary equipment, crevices and the surface of the electric power secondary equipment is removed through hydrophobicity and volatility replacement of the insulation cleaning agent; hot air drying equipment is adopted to dry and blow the surface of the power secondary equipment, so that the surface of the power secondary equipment is dry and moisture-free; the electric power secondary equipment with is sprayed an insulation repairing agent, and then the electric power secondary equipment is dried by adopting hot air drying equipment to form a layer of insulation film on the surface of the electric power secondary equipment; and the insulation value of the power secondary equipment is measured according to regulation requirements, and repair can be completed if the requirements are met. The repair process is scientific, the whole repair can be completed within two hours, the repair efficiency is high, and the power failure time is greatly shortened; and the repair is finished at a time without interruption, so that manpower is saved.

Description

technical field [0001] The invention relates to treatment after water immersion of secondary electric power equipment, in particular to a rapid repair process for external insulation of secondary electric power equipment after water immersion. Background technique [0002] In recent years, due to the destruction of the earth's environment due to the rapid development of global industry, flood disasters have become more frequent. [0003] The recent torrential rains in my country are characterized by short intervals and heavy rainfall. A total of 24 stations have reached or exceeded historical extremes in daily precipitation. Every flood is a serious damage to the relay protection system in the substation. Since the general power distribution room or communication room is placed on the ground floor or first floor, the occurrence of waterlogging is a devastating blow to these power secondary equipment. Such as foreign matter, the external insulation of the equipment is damag...

Problems solved by technology

Since the general power distribution room or communication room is placed on the ground floor or first floor, the occurrence of waterlogging is a devastating blow to these power secondary equipment. Such as foreign matter, the external insulation of the equipment is damaged, which makes the power secondary equipment unable to meet the power transmission conditions, thus prolonging the power outage time of the power secondary equipment due to floods

[0004] In order to deal with the sediment and other foreign matter attached to the secondary equipment of the electric power as soon as possible, the method of washing with water is mostly used at present. Although the sediment and the like can be removed by washing with water, the moisture remaining on the equipment cannot be removed quickly, and it takes one to It takes two days to dry and dehumidify. At the same time, washing with water will cause corrosion and damage to the lines and equipment, which will lay the foundation for future safe power supply.
