The invention relates to a baffle assembly capable of preventing small animals from entering a power transformer and distribution station. The baffle assembly comprises baffle bodies, a limiting mechanism and damping springs. The number of the arranged baffle bodies is two, the baffle bodies are connected to an entrance of the power transformer and distribution station in a left-right symmetry mode, and the two baffle bodies are matched with each other to close the entrance when being closed. The limiting mechanism conducts mechanical limiting on the opened angle of the baffle bodies. The damping springs are connected and mounted on the lower portions of the baffle bodies, and the two ends of each damping spring are connected with one corresponding baffle body and a door frame of the entrance respectively. Compared with the prior art, due to the fact that the damping springs are arranged on the lower portions of the baffle bodies, when the lower portions of the baffle bodies are stressed, the baffle bodies can directly face the compressed direction of the springs, the compressed counter-acting force generated by the springs is maximum, hence, small animals can be well prevented from entering the power transformer and distribution station, and workers can go in and out without any influence.
