PROSPECTS FOR THE APPLICATION OF SYNTHETIC LIQUID DIELECTRICS IN TRANSFORMERS

Y PRIMENENIIA SINTETICHESKIKH ZHIDKIKH DIELEKTRIKOV V TRANSFORMATORAKH

There exists a need for liquid dielectrics capable of operating in conditions under which the requirements for insulating liquids cannot by fully satisfied by petroleum derived oils. This applies to electro-physical parameters, the incombustibility of antiacid stability, and the temperature range of operational capability, which has special significance in the case of utilization of liquids in transformers installed on fire- and explosion-hazardous objects, aircraft, water and underwater vessels, etc. The study examined the properties of various types of synthetic oils (liquids) which appear promising as regards application in transformer construction. These types are oils based on synthetic hydrocarbons and oils based on chlorinated hydrocarbons. The figures and charts include the basic indicators of synthetic hydrocarbon oils, the influence of the structure of alkylbenzyl transformer oils upon their oxidation rate in the electrical field at 95 degrees C., and physical heat characteristics and relative prices of various types of synthetic liquid transformer oils.
