Background
In order to meet the requirement of the high-voltage high-capacity high-frequency transformer on the insulating property and reduce the size of the high-frequency transformer, an epoxy resin pouring mode is often adopted, but the epoxy resin is low in heat conductivity coefficient, and the high-frequency transformer is small in size and large in heat quantity per unit volume, so that the air cooling cannot meet the requirement of power conversion. The water cooling needs to embed a metal water pipe with good heat conduction performance in the high-frequency transformer in advance, in order to ensure that heat generated by the primary winding, the secondary winding and the iron core of the transformer is taken away by cooling water as far as possible, the water pipe should be close to a heat source as far as possible, but the insulation requirements among the primary winding, the secondary winding and the iron core of the high-voltage large-capacity high-frequency transformer cannot ensure that the water pipe can penetrate through each heat source position. When the mode of radiating by a plurality of groups of water pipes is adopted, the number of the interfaces is increased, the probability of water leakage and seepage is improved, the potential of the high-frequency transformer winding is higher, the cooling water and the metal water pipe can generate electrochemical reaction, and the water pipe is blocked after time accumulation. On one hand, the strong oil cooling needs to be provided with an oil storage tank, the size of the high-frequency transformer is increased, on the other hand, when transformer oil leaks, the phenomena of combustion and explosion easily occur, great potential safety hazards are brought to a peripheral power electronic converter, the danger is high, and meanwhile, the complexity of the fire protection design of the device is greatly increased.
