Embodiment 1

[0036] A composite flame-retardant organic decontamination agent for live insulation equipment, which consists of the following raw materials in parts by weight: 85-95 parts of organic solvent, 5-15 parts of stabilizer, and the organic solvent is calculated by percentage by weight: refined Oil 20-40%, flame retardant 15-25%, cleaning agent 20-40%, emulsifying penetrating agent 5-10% and dispersant 5-15%.

[0037] The stabilizer is tert-butylhydroquinone or 1,3-dimethylurea; the flame retardant is Chlorowax-52, Chlorowax-40, decabromodiphenyl ether, four Australian bisphenol A, pentabromotoluene or Hexabromocyclododecane; refined oil after desulfurization treatment, the composition is 8-10C saturated alkanes and unsaturated alkanes; the cleaning agent is a non-aqueous cleaning agent, which can be hydrocarbon solvents, alcohol solvents, ether solvents or hydrocarbons Mixed solvent of solvent and alcohol solvent; emulsifying penetrating agent is fatty alcohol polyoxyethylene ethe...

Embodiment 2

[0039] Composite flame retardant organic detergent for live insulation equipment, 92 parts of organic solvent, 8 parts of stabilizer, organic solvent by weight percentage: 30% of refined oil, 20% of flame retardant, 30% of cleaning agent, emulsified Penetrant 8% and dispersant 12%. Refined oil is desulfurized, the composition is 8-10C saturated alkanes and unsaturated alkanes, the emulsifying penetrating agent is fatty alcohol polyoxyethylene ether, the stabilizer is tert-butyl hydroquinone, and the flame retardant is hexabromocyclododecane Alkanes, the cleaning agent is C12-C16 coconut oil alcohol.

[0040] This composite flame retardant organic detergent is tested as follows:

[0041] Test equipment and conditions: 1) Conductivity tester; 2) Power frequency test transformer 1000KV;

[0042] 3) According to the national standard, the insulator withstand test voltage is as follows:

[0043] Table 1 is the insulator withstand test voltage

[0044]

[0045] 2 Test voltage...

Embodiment 3

[0084] Composite flame retardant organic detergent for live insulation equipment, 90 parts of organic solvent, 10 parts of stabilizer, organic solvent by weight percentage: 32% of refined oil, 25% of flame retardant, 30% of cleaning agent, emulsified Penetrant 6% and dispersant 7%. Others are the same as embodiment 1.

[0085] The composite flame retardant organic detergent is used for the power frequency flashover voltage test on the insulator. The test shows that: during the test, about 75% of the specified flashover voltage is applied first, and then it rises to the flashover voltage at a rate of about 2% of the test voltage per second. The flashover voltage is calculated as the arithmetic mean of 5 consecutively measured flashover values.

[0086] Selected sample: hanging bottle model XP70

[0087] Test transformer: 1000kV

[0088] In order to test the accurate measurement of the voltage step-up process of the transformer, 5 test samples are formed into a string, a tota...

Abstract

The invention discloses a composite flame-retardant organic detergent for charged insulating equipment. The composite flame-retardant organic detergent is prepared from the following raw materials in parts by weight: 85-95 parts of organic solvent and 5-15 parts of stabilizing agent. The organic solvent consists of the following components in percentage by weight: 20-40 percent of refined oil, 15-25 percent of flame retardant, 20-40 percent of cleaning agent, 5-10 percent of emulsification penetrant and 5-15 percent of dispersing agent. The composite flame-retardant organic detergent is wide in application range, can be used for cleaning porcelain insulating electrical appliance equipment of various voltage grades, is high in cleaning degree and can be used for cleaning rapidly and completely. The composite flame-retardant organic detergent is neutral, nontoxic and harmless, and volatilizes completely in a short period of time after being contacted with the air without leaving residual liquid. The composite flame-retardant organic detergent is non-corrosive to equipment, harmless to a human body, and environment-friendly.

Description

technical field [0001] The invention belongs to the field of power grid maintenance, in particular to a composite flame-retardant organic detergent used for cleaning the outer surfaces of medium and high-voltage equipment in substations, switch cabinets, secondary line terminal blocks, oil-carrying equipment and transformer bushings. Background technique [0002] At present, pollution flashover accidents of power equipment in my country occur from time to time. There have been many large-scale pollution flashovers in Northeast China and North China, and each pollution flashover will cause heavy losses. According to the analysis, the main reasons for the harm of pollution (dirt) to power equipment are as follows: [0003] 1. The fine dust in the environment deposits on the outer insulating surface to form a layer of dirt. The dirt layer contains metal particles, oil, dust, and moisture-soluble salts, acids, and alkalis. When encountering fog, dew, and drizzle, etc. In humid ...
