Abstract
The invention belongs to the technical field of insulating oil, and particularly relates to insulating oil for a capacitor and a manufacturing method thereof, wherein the insulating oil is prepared from the following raw materials in parts by weight: 100-150 parts of crude oil, 15-20 parts of sodium hydroxide, 25-30 parts of EDTA, 15-20 parts of naphthenic acid, 5-10 parts of phosphate, 2-5 parts of sodium nitrite, 15-20 parts of triethanolamine and 1-5 parts of benzotriazole. The invention uses vegetable oil and waste oil as crude oil, and then deacidifies and dehydrates, adds other mixtures, the produced insulating oil still has high fluidity at low temperature, and has low pour point and low viscosity at low temperature, because of adding antioxidant, the oxidation stability is very good, and simultaneously, the waste crude oil and vegetable oil are more environment-friendly and cleaner.
Description
Technical field
The present invention relates to transformer oil technical field, relate to a kind of electrical condenser transformer oil and preparation method thereof in particular.
Technical background
Electric insulation oil usually adds oxidation inhibitor modulation by the lubricant base of deep refining and forms.The main dielectric medium being used as electrical equipment.The salient features of electrical apparatus insulation oil is low-temperature performance, oxidation stability and dielectric loss.Low-temperature performance refers under cryogenic, and oil is energy convection current automatically in electrical equipment, derives heat and the necessary mobility of instantaneous trip flame current.Generally all require that electrical apparatus insulation oil pour point is low less with viscosity during low temperature.In electrical equipment, oil is subject to the effect of heat under electric field action and oxygen for a long time and is oxidized.Add the oil product of oxidation inhibitor and metal passivator, its oxidation stability is better.
Capacitive insulation oil is that a class can improve the work field intensity of power capacitor, the electrical condenser individual capacity that increases electric power, improve the working medium of specific characteristic of power capacitor, and it plays a part very important in manufacture High-performance power electrical condenser.In recent years, along with the quick dilatation of national grid, particularly during 12, the investment of country only on extra-high voltage electric transmission and transformation is just up to 570,000,000,000 yuan; Within 2010, national transformer oil consumption is more than 5.5 ten thousand tons, and in recent years also by the rate of increase of maintenance 10%, conservative estimation can reach 80,000 tons by 2015.Therefore, be badly in need of seeking the method that can be prepared capacitor insulation oil simply, efficiently.
Summary of the invention
For solving the problems of the technologies described above, the invention provides described a kind of electrical condenser transformer oil, be made up of the raw material of following parts by weight: crude oil 100 ~ 150, sodium hydroxide 15 ~ 20, EDTA25 ~ 30, naphthenic acid 15 ~ 20, phosphoric acid ester 5 ~ 10, Sodium Nitrite 2 ~ 5, trolamine 15 ~ 20, benzotriazole 1 ~ 5.
Further, described crude oil is the abendoned oil of vegetables oil or discharge, and the abendoned oil of described discharge comprises sewer oil and waste oils and fats.
Further, described sewer oil is depickling and the oil after dewatering.
Further, described antioxidant is oil-soluble inhibitor.
Further, described EDTA is interacted by quadrol, sodium cyanide and formalin and is made.
The making method of described electrical condenser transformer oil, comprises following methods step:
1) collection refines crude oil, and carries out depickling process, carry out processed after depickling completes to sewer oil or discarded vegetable and animals oils;
2) add crude oil in reactor, then add sodium hydroxide and EDTA, fully stir and sodium hydroxide and EDTA are dissolved completely;
3) add naphthenic acid, phosphoric acid ester, Sodium Nitrite, trolamine, phenylhydrazine triazole stir and be warmed up to 70 DEG C and carry out homogeneous, be finally cooled to normal temperature and obtain transformer oil.
Further, the method for described stirring is put into still by agitator and is stirred, and stirring velocity is 100 ~ 500r/min.
Beneficial effect of the present invention is:
The present invention utilizes vegetables oil and the waste oil that dumps as crude oil, again by depickling and processed, add other class compound, the transformer oil produced still has very high mobility at low temperatures, and pour point is low less with viscosity during low temperature, owing to adding antioxidant, make its oxidation stability very good, make use of discarded crude oil and vegetables oil environment-protecting clean more simultaneously.
