ZGS -F35 series of wind turbines with a combined transformer is a wind turbine components will be sent to the high voltage of 0.6-0.69 KV after 35 KV, and net output of special equipment. Different from the traditional box-type substation, the high voltage load switch, fuse, and high-voltage componets and the transformer device body, no circuit tap were sealed in two separate oil chamber, the structure bu Minato. According to the configuration of low-voltage power distribution needs
