Description
Technical field
The present invention relates to industrial lubricant technical field, particularly relate to a kind of transformer oil having lubricant effect concurrently.
Background technology
In recent years, occur in electric power accident both domestic and external people are recognized the safety of power system relates to the safety of entire society's economic life.In the process of power system power transmission and transformation, transformer is as the tie of delivery of electrical energy, and be one of equipment of most important and most critical in power equipment, its safe and stable operation is related to the steady running of whole electrical network.Operation transformer in systems in which, once there is major accident, not only can cause the autoclasia of equipment, also can interrupt the electric power supply of power network, causes tremendous influence to the production of society and life.Especially the voltage range along with power system is more and more higher, the progressively deterioration problem of the transformer insulated characteristic of long-time running in power system seems more outstanding, therefore, improve the insulation characterisitic that transformer runs, suppress aging of insulation in transformer, thus reduce that insulating fault become a reality in the urgent need to.Transformer oil is as dielectric most important in power transformer, and assume responsibility for the dual role of heat radiation and insulation, therefore, the heat dispersion and the insulating property that how to improve transformer oil receive more concern.Traditional transformer oil thermal conductivity is less, do not meet more and more higher radiating requirements, secondly more and more higher voltage range and miniaturization all require that dielectric must have higher insulation strength, based on this, in order to adapt to the developing direction of transformer Large Copacity, extra-high pressure grade and miniaturization, improve the insulation characterisitic of traditional transformer oil long-time running, research insulating property are higher, the better transformer oil of thermal ageing properties is extremely urgent.
