[0036] When installing the power distribution cabinet body 1, first, the concrete base 2 is poured at the position where the power distribution cabinet body 1 is to be installed. When pouring the concrete base 2, the foot bolts 3 are poured into the concrete base 2 according to the size of the base platform 4. After the concrete platform is poured, the base platform 4 is placed on the concrete base 2 and fixed by the foot bolts 3. The base platform 4 supports the support adjusting mechanism 5. Then, the power distribution cabinet body 1 is directly placed on the support adjusting mechanism 5. When the power distribution cabinet body 1 is inclined, the support adjusting mechanism 5 is used to adjust the power distribution cabinet body 1 so that the power distribution cabinet body 1 can be kept horizontal. Then, the anti-seismic support mechanism 6 on both sides of the power distribution cabinet body 1 is used to abut against the ground to further support the power distribution cabinet body 1. The installation of the power distribution cabinet body 1 is completed. Then, the transformer is installed in the power distribution cabinet body 1. By using the support adjusting mechanism 5 on the base platform 4 to support and adjust the power distribution cabinet body 1, the possibility of the power distribution cabinet body 1 being inclined during installation can be reduced, and the possibility of the power distribution cabinet body 1 being unstable when installing the transformer later can be reduced.

[0037] With reference to Figure 1 , Figure 3 and Figure 4 , the support adjusting mechanism 5 comprises a support plate 51 arranged on the base platform 4. Four adjusting threaded rods 52 symmetrically arranged in pairs are arranged between the support plate 51 and the base platform 4. An adjusting sleeve 53 is arranged on the adjusting threaded rod 52.

Then whether the power distribution cabinet body 1 is deviated is measured again. When the power distribution cabinet body 1 is deviated, the corresponding adjusting threaded rod 52 and adjusting sleeve 53 are rotated again for adjustment. By adjusting the support plate 51 by using the adjusting threaded rod and the adjusting sleeve 53 before placing the power distribution cabinet body 1 on the support plate 51, the support plate 51 is kept in a horizontal state, so that the possibility of inclination of the power distribution cabinet body 1 during installation is reduced, and the possibility of instability of the power distribution cabinet body 1 during installation of the transformer later is reduced.
