Abstract

The invention discloses a novel transformer. The novel transformer comprises a shell, an iron core and a winding, and is characterized in that: a resin curing layer is adhered to the periphery of a conducting wire in the winding, and the iron core and the winding are soaked in insulating liquid in the shell. The conducting wire in the winding is cured by an insulating material with higher heat resistance, such as resin, has a fixed relative position, enhances the mechanical strength and the heat resistance of the entire winding, has stable running quality, strong short-circuit resisting and overloading capacity, and adopts the liquid with high insulating property and strong convective heat-sinking capacity for insulation so as to keep the high efficiency of an oil-immersed transformer. The novel transformer is particularly suitable for environments with high short circuit probability and frequent overloading impacts.

Description

technical field [0001] The invention relates to a power transformer, in particular to a novel transformer with high mechanical strength, strong short-circuit resistance capability and high efficiency. Background technique [0002] At present, power transformers mainly include dry-type transformers and oil-immersed transformers. The winding wires of dry-type transformers are sealed with epoxy resin or wrapped with NOMEX paper, and air is used as the insulating medium. They have high mechanical strength and strong short-circuit resistance, but low efficiency. The winding wires of oil-immersed transformers are wrapped with cable paper, and transformer oil is used as the insulating medium. The efficiency is high, but the overall mechanical strength is poor and the short-circuit resistance is weak. Contents of the invention [0003] The object of the present invention is to overcome the above disadvantages and provide a novel transformer with high mechanical strength, strong s...
