In order to strengthen the connection stability between the base plate 310 and each of the first elastic members 330 , in one embodiment, a plurality of first fixing grooves 311 are defined on the side wall of the base plate 310 , and the end of each first elastic member 330 is inserted into a The first fixing groove 311 is connected to the base plate 310 . The first fixing groove 311 further reinforces the installation position of the first elastic member 330, and at the same time, limits the deformation direction of the first elastic member 330 to ensure structural stability. The first elastic member 330 is inserted into the first fixing groove 311 to connect to the substrate 310 , thereby enhancing the connection strength between the substrate 310 and the first elastic member 330 . In this way, the connection stability between the base plate 310 and each of the first elastic members 330 is improved, and the structural stability of the high and low voltage prefabricated substation with good protection performance is guaranteed.

Further, in order to strengthen the connection stability between the box body 100 and each of the first elastic members 330 , in one embodiment, a plurality of second fixing grooves 150 are formed on the inner side wall of the box body 100 . The end is inserted into a second fixing groove 150 and connected with the box body 100 . The second fixing groove 150 further reinforces the installation position of the first elastic member 330, and at the same time, limits the deformation direction of the first elastic member 330 to ensure structural stability. The first elastic member 330 is inserted into the second fixing groove 150 to connect the box body 100 , thereby enhancing the connection strength between the box body 100 and the first elastic member 330 . In this way, the connection stability between the box body 100 and each of the first elastic members 330 is improved, and the structural stability of the high and low voltage prefabricated substation with good protection performance is guaranteed.
