Supporting mechanism for high-voltage power distribution cabinet and use method of supporting mechanism

The invention discloses a supporting mechanism for a high-voltage power distribution cabinet and a use method thereof, and relates to the technical field of high-voltage power distribution cabinet mounting, supporting and protection, the supporting mechanism comprises a power distribution cabinet and a protection foundation, and also comprises two supporting cross beams slidably mounted on two side walls in the protection foundation; the fixing part is located on the two supporting cross beams and used for installing and supporting the power distribution cabinet, a porous steel plate is fixedly installed on the two supporting cross beams jointly, and the porous steel plate is fixed to the bottom of the power distribution cabinet through bolts. When the supporting mechanism of the high-voltage power distribution cabinet operates, displacement generated by vibration is decomposed into displacement in the vertical direction and the horizontal direction, the occupied space of a vibration reduction structure in th
