Moreover, due to the particularity of the structure of the transformer substation building and the operation characteristics of related equipment, the transformer substation has strict requirements on fire prevention work. In the process of designing and constructing the converter transformer, a large amount of combustible materials such as insulating materials and transformer oil are used, and meanwhile, once the power problem occurs in a high-voltage, high-current and high-load working environment, the probability of fire of the transformer substation is invisibly increased.
