oil-immersed transformer
1.Electromagnetic winding, motor, high temperature transformer, electric tools, special electromotor, refrigeration compressor, oil immersed transformer, etc.
2.This paper dissertates by the numbers the feasibility that the heat pipe technology applies in oil-immersed transformer, sums up the latest national inside and outside research fruits, puts forward an new scheme applying heat pipe in the transformer, sets up the way and the model of calculation according to the 10-kVA electrical transformer and designs a program written in VC++ language to calculate the temperature rise of the heat pipe transformer.
3.The oil leakage reasons of oil-immersed power transformer are analysed. The features of fibre cork rubber and its application in omni-sealed transformer are introduced.
4.This type of combined transformer consists of two single-phase all-insulated voltage transformers and two current transformers, divided into two types—oil-immersed type and dry type, its primary and secondary outlet terminals are led out respectively through insulating porcelain jacket, outside the transformer tank there is equipped with electric meter box, which can be installed integrally with the combined transformer or hung up separately.
