Combination transformer is a transformer that combines the body of the step-up transformer, switchgear, fuses, tap changers, and corresponding auxiliary equipment. The high-voltage switch and fuse are installed in the oil tank, and the overall external dimensions are small. Its structural form is similar to the box transformer introduced from the United States in the 1990s. According to the product structure and component configuration, it can be divided into two types: one is a fully insulated box type product, and the other is a common box type product with dry-type bushing for high-voltage output.
