Compared with prior art, when this utility model uses, cold air is blown into by air intake cross flow fan, sets through transformator etc.
Standby air heats, rises to air-out cross flow fan and flows out, and makes air-flow define natural wind circulation in electric substation, needs to change
During maintenance transformator, promote two grades of lifting columns, make hoistable platform maintain an equal level with ground, complete to change so that staff keeps in repair
Need not be directly entered melt pit during replacing, work convenient safety；And this utility model simple in construction, practical.
Accompanying drawing explanation
Fig. 1 is the structural representation of buried electric substation.
Detailed description of the invention
Below in conjunction with detailed description of the invention, the technical scheme of this patent is described in more detail.
Referring to Fig. 1, a kind of buried electric substation, including underground box 1, sunk elevator 2, air intake cross flow fan 5 and
Air-out cross flow fan 6, is provided with sunk elevator 2 in described underground box 1, sunk elevator 2 includes two grades of lifting columns
21, two grades of lifting column 21 case located underground 1 both sides, two grades of lifting column 21 subordinate upper ends are provided with hoistable platform 22, and lifting is flat
Platform 22 is interval with low-voltage cabinet, high-voltage board and transformator；During installation, first hoistable platform 22 is risen and maintains an equal level with ground,
The reversing of equipment waggon charging appliance enters hoistable platform 22, makes transformator fall on hoistable platform 22, controls two grades of liftings
The subordinate of post 21 declines, and makes transformator be down in melt pit；When needing repair and replacement transformator, promote two grades of lifting columns 21,
Make hoistable platform 22 maintain an equal level with ground, complete to change so that melt pit, work when staff keeps in repair replacing, need not be directly entered
Make convenient safety；Described sunk elevator 2 top is fixedly connected with top cover 3, and described top cover 3 left and right sides is symmetrical
It is provided with through hole 4, the through hole 4 on the left of top cover 3 is provided with air intake cross flow fan 5, the through hole 4 on the right side of top cover 3 is installed
