The invention discloses a box type transformer flooding safety suspension installation mechanism. The mechanism comprises a shell, waterproof plates are uniformly distributed on the inner side wall ofthe shell in the vertical direction, a transformer is arranged on the inner side of each waterproof plate, a locating plate is relatively fixed to the upper surface of each transformer, the box typetransformer flooding safety suspension installation mechanism is simple in structure and convenient to install, by means of the shell, protection to the transformers is achieved, the lower end of theshell is of a sealed structure, heat emission holes are formed in the side face of the upper end of the shell, transformer flooding caused by poor surface drainage in rainy days is effectively avoided, normal operation of the transformer is guaranteed, the disassembling and maintaining rate is lowered, the transformers adopt the suspension installation mode of entering from the upper side of the shell, suspension of the transformers is achieved through the locating plates and bearing columns, and by means of the waterproof plates, it is guaranteed that cavity through holes between the transformers and the shell are normal; meanwhile, the phenomenon that rainwater enters from the heat emission holes is prevented, the heat dissipation effect of the transformers is guaranteed, and better convenience is brought to use.
