Detailed Description

The utility model relates to a high security performance prepackage type transformer substation, as shown in fig. 1, including transformer substation's body 5, be provided with roof 2 on the transformer substation's

body

5, 2 lateral walls on roof can be as in fig. 1 slant setting, avoid the rainwater to squeeze into the transformer substation when rainy day, also can vertical setting. Be provided with first recess on the roof 2, sliding connection has rack 1 in the first recess, the one end of rack 1 and electric putter 10's expansion end fixed connection, electric putter 10's stiff end and first recess inner wall fixed connection can drive rack side-to-side movement (left and right direction in the picture) through electric putter 10's back and forth movement.

A plurality of half-tooth gears 3 meshed with the rack 1 are arranged below the rack 1, the half-tooth gears 3 are rotatably connected with a support shaft 9, two ends of the support shaft 9 are fixedly connected with two side walls of the first groove, and the pushing distance of the electric push rod 10 can be set, so that when the electric push rod 10 pushes, the rack 1 is always kept meshed with the half-tooth gears 3 and cannot be disengaged; and a fan blade 4 is fixedly arranged at one end of the half-tooth gear 3, which is far away from the teeth, and the lower end of the fan blade 4 extends into the transformer substation body 5. It can be understood that, when the electric push rod 10 moves back and forth, the rack 1 can drive the fan blade 4 to rotate back and forth to perform fanning by taking the support shaft 9 as a rotation center, so as to accelerate the flow speed of the gas in the substation.

The transformer substation body 5 is placed on placing platform 6, place platform 6 protrusion in ground setting, transformer substation body 5 bottom surface is provided with several through-hole 12, place on the platform 6, perpendicular and through-hole 12 axial direction is provided with ventiduct 7 that link up, ventiduct 7 and through-hole 12 intercommunication. The ventilation duct 7 is communicated with the through hole 12 formed in the bottom surface of the substation body 5 and the outside to form a duct, so that air in the substation body 5 can be connected with the outside air through the ventilation duct 7. When temperature in the transformer substation body 5, humidity are not high, only can reach the radiating purpose of cooling through-hole 12 and external intercommunication passageway, when temperature or humidity in the transformer substation body 5 reach the warning value, electric putter 10 on the roof 2 starts, and the fan is carried out in the fan 4 horizontal hunting, and wind blows from the top down this moment, and it is outside to discharge transformer substation body 5 through ventiduct 7, takes away heat and moisture in the transformer substation body 5.

And shutters 8 are symmetrically arranged on two side walls of the transformer substation body 5. When the fan blades 4 on the roof 2 start to work, the louver 8 can accelerate the speed of heat dissipation in the transformer substation body 5 so as to achieve the purpose of rapid cooling; when the fan blades 4 do not work, the symmetrically arranged shutters 8 can also form convection, so that heat in the substation body 5 can be conveniently dissipated.

A second groove is formed in the first groove in the roof 2 and in a position corresponding to the fixed end of the electric push rod 10, and the fixed end of the electric push rod 10 is fixed in the second groove. The depth of the second groove is equal to the length of the fixed end of the electric push rod 10, and the electric push rod 10 is arranged in the second groove, so that the distance between the end part of the rack 1 and the inner wall of the first groove can be shortened, the fan area of the fan sheet 4 is wider, and the fan dead angle is reduced.

Third grooves which are symmetrical are arranged in the first groove on the roof 2 along the length direction, supporting plates 11 are arranged on two sides of the rack 1, and the supporting plates 11 are in sliding fit with the third grooves. The support plate 11 can support the rack 1, limit the rack 1 and prevent the rack 1 from being disengaged from the half-tooth gear 3 due to overlarge moving distance.
