Problems solved by technology

This will lead to condensation or ice crystal effect on the surface of the object to be cleaned, forming a water film or thin ice, resulting in a sharp drop in the surface insulation resistance of the equipment, an increase in leakage current, and even a short circuit, causing an accident
[0004] Chinese patent published No. 96102785 patent application for invention in 1996. The invention claimed that electrical and electronic equipment can be charged and cleaned, but did not provide important indicators such as withstand voltage and the upper limit of voltage allowed during charging cleaning. In addition, the item CFC-113 is used in the invented cleaning agent formula. This substance has been proved to be an ozone depleting substance (ODS), which will destroy the ecological environment of the earth and cause serious harm to humans and other organisms. It is expressly prohibited by international conventions. Ozone Depleting Substances (ODS) Used

Embodiment Construction

[0034] As can be seen from the test results of Table 1, Table 2 and Table 3, the high-voltage electrified cleaning agent involved in the present invention has the following novelties:

[0035] (1) Does not contain ozone-depleting substances (ODS) banned by international conventions;

[0036] (2) The lifetime in the troposphere is less than 10 years, the ozone depletion potential (ODP) is not greater than 0.03, and the global warming potential (GWP) is not greater than 0.1.

[0037] (3) It has the advantages of no flash point and no combustion;

[0038] (4) It is safe to clean high-voltage power equipment under the working voltage of up to 500KV;

[0039] (5) There will be no ice crystal effect during live cleaning of high-voltage power equipment;

[0040] (6) There will be no condensation when the high-voltage power equipment is charged and cleaned;

[0041] (7) When the high-voltage power equipment is charged and cleaned, the surface insulation value of the equipment will ...

Abstract

The cleaning agent consists of HFE7100, C11-C17 high-boiling point alkane, tetrachloroethylene, C4-C11 alkane, acetone and stabilizer. It may be used in the cleaning and maintenance of live high-voltage power equipment up to 500 KV. It contains no ODS, produces no daw fall and ice crystal, and is safety and high in cleaning effect.

Description

technical field [0001] The invention relates to a charged cleaning agent for high-voltage electrical equipment. Background technique [0002] All kinds of dust and dirt floating in the atmosphere include inorganic dust, oil stains, and tiny liquid droplets containing electrolytes formed by condensation. This complex atmospheric environment, under the action of various forces between substances, will cause a layer of complex dust to be deposited on electrical and electrical equipment that has been in operation for a period of time. This kind of dust will inevitably have a negative impact on electrical and electrical equipment. Slight cases will reduce the heat dissipation capacity of the equipment and affect the operating quality and reliability of electrical and electrical equipment; severe cases will cause chemical corrosion and shorten the service life of the equipment; more serious It will also cause a flashover in the power grid, and even cause a fire, which will bring ...
