Prefabricated accident oil pool for transformer substation

The utility model provides a prefabricated accident oil pool of a transformer substation, and belongs to the technical field of accident oil pools. The purpose is to solve the problems of construction period and environmental protection caused by cast-in-place concrete foundations and the problem of multiple types of consumed formworks. According to the technical scheme, the accident oil pool comprises a plurality of prefabricated standard oil pools, each standard oil pool is of a closed cavity structure, an oil inlet and an oil outlet are formed in each standard oil pool, each standard oil pool is communicated with the adjacent standard oil pool through an oil pipe at the oil inlet or the oil outlet, and the accident oil pool forms a communicating vessel structure; the standard oil pool has the advantages that the standard oil pool is completely prefabricated in a factory, construction procedures are reduced, and the construction period is shortened; the template types are reduced, the influence on the envir
