[0035] In combination with the first and second embodiments, the main transformer can be effectively fixed by using the normal fixed structure, and the station external maintenance of the main transformer is more convenient by using the flexible inclined outward moving structure, so that the cumbersome operation of temporarily laying the station external track when the main transformer needs to be urgently repaired is avoided; the station external movement of various electrical equipment in the transformer substation can be realized by using the inclined transposition mode, and the transformer substation can always be kept dry by using the overhead and convection ventilation structure during the normal operation of the transformer substation; the mutual use of the two can effectively improve the station external repair efficiency of the main transformer and the operation and stability of the transformer substation.

[0036] The process and principle of the utility model are as follows:

[0037] Step 1: when the main transformer is moved outward, first, the maintenance rail plate 10 is lowered, so that the bottom of the maintenance rail plate 10 is in contact with the bottom plate 1, and then the self-propelled wheels on the bearing table 15 are started, the self-propelled wheels drive the bearing table 15 and the main transformer above to move, in this process, the main transformer on the unit guide rail 8 is moved to the straight rail plate 7 through the direction-changing guide rail 9;

[0039] Step 3: then the electric push rod 21 is started to extend, which drives the maintenance rail plate 10 to gradually present a horizontal state, that is, to move outward from the transformer substation, so as to achieve the purpose of convenient maintenance.
