Abstract
The invention provides an anti-explosion dehumidifying solvent for a transformer, aiming at the defects of easy kerosene volatilization and accident occurrence of a dewatering medium, i.e. kerosene used for large-size oil transformer, in operation. The anti-explosion dehumidifying solvent for the transformer is prepared by a plurality of chemical raw materials according to a certain process. The invention has few raw materials, simple production process, production without three wastes discharge and low boiling point of produced mixed solvent, can greatly enhance the production safety factor of the large-size oil cooling transformer, prevents the accidents, can be repeatedly used for multiple times and reduces the production cost.
Description
Affiliated technical field
The invention discloses a kind of anti-explosion dehumidifying solvent for transformer and manufacture method thereof, belong to the chemical products production technical field, the product that this method is produced is mainly used in the large-scale oil cooled transformer of ultra-high voltage transformer station.
Background technology
The high-power transformer that ultra-high voltage transformer station is used needs oil cooling but, in the cooling transformer process that produces oil, before perfusion transformer heat conduction cold oil operation, the high-power transformer integrated member must be carried out the dehumidifying processed, make the moisture content of high-power transformer integrated member drop to ten thousand/below, during processing integrated member is flooded kerosene in the vacuum impregnation jar, allow kerosene be penetrated in the capillary micropore of insulating material, utilize the dissolution of kerosene to micro-moisture, micro-moisture in the transformer integrated member and kerosene are thoroughly removed totally, in the horizontal degassing tank of high vacuum, heat then and carry out secondary vacuum and handle, the lamination wood that uses in the particularly large-scale oil cooled transformer, cable paper, hydrophilic insulants such as fiberglass products, all need handle, to guarantee its insulativity through this operation.But there is following defective in this treatment process: this is because kerosene can volatilization gas when handling, the gas that kerosene volatilizes is flammable explosive gas, though the operation of this link requirement is very strict, potential risks still exist, in case misoperation will set off an explosion, consequence is very serious.
Summary of the invention
Volatile at the kerosene that this dehydration medium of kerosene of large-scale oil change use is in operation, as to cause the accident easily defective, the invention provides a kind of anti-explosion dehumidifying solvent for transformer, it is not only simple to operate but also be safe from danger to utilize this anti-explosion dehumidifying solvent for transformer that transformer is carried out the deep dehydration of integrated member.
Taked following technical scheme for realizing purpose of the present invention:
A kind of anti-explosion dehumidifying solvent for transformer, this anti-explosion dehumidifying solvent for transformer are that the feedstock production by following weight portion forms: industry anhydrous ethanol, acetone, toluene, ethyl acetate, carbon dichloride, inorganic dehydrating agent; The consumption of each raw material is respectively by weight:
Industry anhydrous ethanol 5-70 part, acetone 5-90 part, toluene 5-30 part, ethyl acetate, 5-30 part, carbon dichloride 5-20 part, inorganic dehydrating agent 5-15 part.
The present invention also provides the preparation method of this anti-explosion dehumidifying solvent for transformer simultaneously, and its preparation method is:
Raw material → add inorganic dehydrating agent → stirring → filtration → finished product.
Whipping temp among the preparation technology of the present invention is 20 ℃-30 ℃, and mixing time is 1-2 hour.
Raw material of the present invention can be one or more in ethanol, acetone, toluene, ethyl acetate, the carbon dichloride.
Remarkable advantage of the present invention is raw materials used few, and production technology is simple, three-waste free discharge in the production; The mixed solvent boiling point of producing is low, can greatly improve the production safety coefficient of large-scale oil cooled transformer, and the accident of stopping takes place; Can repeatedly use repeatedly, reduce production costs.
