Pad-mounted transformer is a widely used product in distribution systems. Unlike European style box transformers, it is not a simple combination of transformers and high/low switchgear, but a comprehensive electrical equipment developed on the basis of transformers. Its characteristic is to comprehensively simplify the structure of the high-voltage side load switch and the ring network switch, and immerse them in the same oil tank as the transformer, thus greatly reducing the volume and corresponding cost reduction; Another characteristic is the use of dual fuse protection, where the fuse has current and temperature dual sensitivity characteristics, greatly improving protection sensitivity and reliability. The fully enclosed and insulated performance of Pad-mounted transformer makes installation quick and simple, eliminating the need for long-term maintenance. Since the 1980s, American style box transformers have been widely used in distribution systems in Europe and the United States, especially in the United States. This type of box transformer accounts for 80% -90% of distribution transformers.
