Entropy Weight Detection Technology of Special Transformer Capacity Under Complex Working Conditions Without Power Failure

The capacity detection of special transformer under complex working conditions is easily affected by random noise on site, which leads to poor detection effect. In order to solve this problem, the entropy weight method is proposed to detect the capacity of special transformers under complex working conditions without power failure. Constrained variational model is constructed to obtain fault detection information. Detect the connection of transformer winding wires, calculate the power supply voltage on the loop, and detect the defects of transformer insulation winding. By calculating the contact point temperature between the bushing lead and the inner conduit, the defects of transformer insulation bushing are analyzed, and the capacity entropy weight method for special transformer under complex working conditions is realized. The experimental results show that the proposed technology can accurately detect the turn-to-turn short circuit fault of special transformer, and the fitness curve approaches the optimal value with iteration.
