Description

Drainage base and box-type transformer substation Technical Field The utility model relates to the technical field of box-type substations, in particular to a drainage base and a box-type substation. Background The novel box-type transformer substation plays an important role in the field of new energy power generation, is widely applied to photovoltaic power generation and wind power generation projects, fully fuses the technical characteristics of American box-type transformer substation and European box-type transformer substation in the design process, and has the advantages of small occupied area, high operation safety, high maintenance convenience and the like. The existing Hua type box-type transformer substation mainly comprises a high-voltage chamber, a low-voltage chamber and a transformer, and the three parts are fixedly arranged on a base.
