Description
Technical field
The invention belongs to capacitor processing technique field, and in particular to a kind of soybean oil processing for capacitor impregnant
Technique.
Background technology
Insulation for oil immersed apparatus, widely used earliest is mineral oil, because it is with good thermal conductivity, insulation
Property, and it is cheap.Nineteen thirties once adopted used flame retardancy insulating oil polychlorinated biphenyls, because it has severe toxicity,
Environment is polluted, has been disabled in the whole world.Thereafter the capacitor impregnant used both at home and abroad has：Alkylbenzene（AB oil）, phenyl diformazan
Diphenylphosphino ethane（PXE, also known as diarylethane, S oil）With mono-/bis-benzyl toluene（M/DBT is also known as C101）.Wherein alkylbenzene be
Polychlorinated biphenyls once adopted a kind of used synthetic insulating oil after forbidding use, its electric physical property is better than mineral oil and price is low
It is honest and clean, but its pumping property is poor, so as to limit the raising of capacitor work field strength.Phenyl xylyl ethane and mono-/bis-benzyl
The electric durability of base toluene can be excellent, inspiratory good, but they have a kind of niff, often make one to be difficult to bear in production
By.PXE and C101 is currently mainly used as impregnating agent in China's Power capacitor industry.
Above-mentioned several impregnating agent are all hypotoxicity and are unable to complete biodegradable.With the raising of people's environmental consciousness
With the requirement of sustainable development, electric property is good, nontoxic and fully biodegradable vegetable oil becomes international academic community again
The impregnating agent of concern.Find in practical applications, although vegetable oil（Such as soybean oil oil）Thermal coefficient of expansion, flash-point, ignition point,
Breakdown voltage etc. is all relatively good, but the parameter such as its solidification point, dielectric coefficient, dielectric loss is then not satisfactory, limits it and is used as dipping
The type and function of the capacitor of agent.
The content of the invention
The present invention is intended to provide a kind of soybean oil treatment process for capacitor impregnant, the soybean oil synthesis after processing
Characteristic is preferable, optimizes it and uses characteristic.
The present invention is achieved through the following technical solutions：
A kind of soybean oil treatment process for capacitor impregnant, includes the following steps：
（1）Impurity elimination is handled：
Soybean oil to be processed is put into hermetically sealed can, attapulgite, 0.2% salt of its gross mass 0.5% is added, constantly stirs
After mixing uniformly, after standing storage 3 ~ 4 days, it is filtered, it is spare after elimination impurity；
（2）Alkalization dewaxing：
By step（1）Soybean oil after processing is put into reaction kettle, its gross mass 0.5 ~ 1.5% is added into soybean oil removes wax
Liquid, it is 8.0 ~ 8.5 to adjust soybean oil pH value, is then constantly stirred 1 ~ 2h with 400 ~ 500 revs/min of rotating speed, then
It is 1 ~ 2h of freezing processing under conditions of -4 ~ -8 DEG C to be placed on temperature, and filtration treatment standby is carried out to it with oil filter after taking-up
With；It is described to go each material composition and corresponding percentage by weight in wax liquor as follows：7 ~ 10% pentamethylene, 4 ~ 6% n-hexanes, 2 ~ 5% 4
Cycloheptane, 8 ~ 12% ether, 3 ~ 5% urea, 2 ~ 4% neopelexes, surplus are water；
（3）Acidification：
By step（2）Soybean oil after processing is put into reaction kettle, and the glue that goes of its gross mass 1 ~ 2% is added into soybean oil, is adjusted
It is 6.0 ~ 6.5 to save soybean oil pH value, is then constantly stirred 2 ~ 3h with 500 ~ 600 revs/min of rotating speed, is used after taking-up
Oil filter carries out it spare after filtration treatment；It is described to go each material composition and corresponding percentage by weight in glue as follows：6~
10% zinc chloride, 4 ~ 7% manganese sulfates, 5 ~ 8% calcium sulfate, 1 ~ 2% yttrium nitrate, 10 ~ 15% sodium sulfate of polyethenoxy ether of fatty alcohol, surplus
For water；
（4）Purification processes：
By step（3）Soybean oil after processing is put into distiller, and it is 200 ~ 210 DEG C that heating, which keeps temperature, and holding vacuum is
60 ~ 70Pa, the condensed device of obtained component are collected after being cooled to 17 ~ 25 DEG C.
Further, step（1）Described in attapulgite granular size be 500 ~ 600 mesh.
Further, step（2）Described in the pressure of oil filter be 0.3 ~ 0.4MPa.
Further, step（3）Described in the pressure of oil filter be 0.4 ~ 0.5MPa.
The present invention has the advantages that：
The defects of present invention is directed to existing soybean oil has carried out it improvement processing, and alkalization dewaxing operation reduces its wax, phosphorus
The content of fat etc., acidification operate the content for reducing colloid, gossypol etc., and purification processes operation reduces moisture, saturated fat
The content of fat acid etc., improves the content of monounsaturated fatty acid, and reduce influences soybean oil to the full extent uses quality
Component content, improve the performance parameters such as its solidification point, dielectric coefficient, dielectric loss, enhance its usability as impregnating agent
And function, and holistic approach processing is simple, can complete to improve operation under condition of normal pressure, there is good promotional value.
