As a renewable,pollution-free clean energy source,wind energy has invested heavily in solving problems such as economic and social progress,resource and environmental coordination,and wind energy power generation under the impact of increasingly exhausted fossil fuels and as mankind pays more attention to the deterioration of the global environment.A large amount of money has been invested to develop new and renewable energy sources.Because there is no oil,there will be no problems such as fire,explosion,and pollution,and loss and noise have been reduced to a new level.Therefore,an important equipment in the wind turbine is the dry-type transformer,which is widely used in the power generation system of new energy wind turbines.The DC resistance inspection of dry-type transformers is required to be carried out in the preventive test specifications.The imbalance rate of DC resistance of a transformer is crucial to its performance.The DC resistance test is to prevent problems such as winding wire breakage,joint welding,poor contact,and inter-turn short circuits from occurring during transportation,installation and operation,and to check the winding quality and circuit integrity.The DC resistance imbalance rate of dry-type transformers also affects data parameters such as current and voltage on the high and low voltage sides of the transformer during normal operation.
