Specific embodiment
In order to clarify the technical characteristics of the invention, being illustrated below by specific embodiment to this programme.
A kind of dry-type transformer cooling system as shown in Figure 1, including the transformer case 8 and air-conditioning being located in switchgear house 9
5, a side bottom of the transformer case 8 is equipped with several air inlets transversely arranged, and air inlet quantity is in the present embodiment
Three, and the spacing between each air inlet is equal.
Air inlet is provided with choke plate 7, and choke plate can close air inlet, and the choke plate 7, which is connected with, drives its edge
The electric pushrod 6 of side wall of outer shell sliding, is additionally provided with the upright guide rail positioned at air inlet two sides, two guide rail phases on transformer case
Pair side be equipped with the track groove slided up and down for the choke plate, when can avoid choke plate by setting track groove and moving
Deflection, and when choke plate is fallen, choke plate is improved to the leakproofness of air inlet.It is fixedly installed in the inner cavity of air inlet
Filter screen prevents the sundries such as insect from entering, ensure that the operational safety of transformer.
Air outlet that is several and transversely arranging is provided at the top of transformer case, air outlet and air inlet are in the longitudinal direction
Interlaced arrangement, each air outlet pass through branch pipe 3 respectively and are connected to discharge pipe, and the connection of discharge pipe 2 is located at the air-introduced machine 1 outside switchgear house,
Solenoid valve 4 is installed, for controlling the on-off of branch pipe on each branch pipe.
2 section of discharge pipe of the present embodiment is rectangle, and discharge pipe is interior to be prevented equipped with top edge and top plate by the way that horizontal axis is hinged
The height of contrary wind plate 10, anti-reverse aerofoil is greater than discharge pipe cavity heights, and the width of anti-reverse aerofoil is adapted to discharge pipe lumen width,
Anti-reverse aerofoil is obliquely installed, and the lower edge of anti-reverse aerofoil is located at horizontal axis close to the side of air-introduced machine.By the way that anti-reverse aerofoil is arranged, subtract
The hot outdoor air in transformer case is back to by discharge pipe less, anti-reverse aerofoil uses plastic plate, lighter in weight, transformer

The controller connect is equipped with temperature sensor in transformer case, and the temperature sensor is also electrically connected with controller, and will
Temperature signal reaches controller.
In use process, distribution room temperature lowering is given by air-conditioning, if the received temperature signal of controller is greater than the set value,
Air-introduced machine starting is then controlled, and is lifted up choke plate by electric pushrod, the indoor cold air of distribution is changed with winding surface
Outdoor is drained into through air-introduced machine after heat and reaches cooling purpose, until temperature is less than setting value, air-introduced machine stops, and will by electric pushrod
Choke plate pushes down on, and air inlet is closed, and the heat in transformer case is avoided to enter switchgear house；In air-introduced machine work,
Choke plate can also be moved to the semi-closed position to air inlet, make to enter the wind sectional area less than outlet air sectional area, air-introduced machine exhausting
In the process, cold air is improved using pressure difference and enter the speed of transformer case, to improve cooling effect；Also it can control air inducing
Machine and electric pushrod staggeredly act, and when air-introduced machine works, choke plate completely encloses air inlet, and air-introduced machine is empty by the heat in shell
Then gas extraction stops air-introduced machine to make shell is inside and outside to have pressure difference, open air inlet, make indoor cold sky using pressure difference
Gas, which enters in transformer case, to exchange heat, and is then shut off air inlet, keeps cold air heat exchange more abundant, until temperature is more than to set
When definite value, restart air-introduced machine, so recycle, the cooling effect both realized also reduces energy consumption, save run at
This.
