Detailed description of the invention
As Figure 1-Figure 4, for a kind of air-cooled transformer of the present invention, including transformer base, iron core and coil windings
(not shown), described coil windings parcel is around being located on iron core, and described iron core and coil windings are arranged in transformer base
Portion, this transformer base includes the second pedestal 2 that the first pedestal 1 is in mating connection with the first pedestal 1；First pedestal 1 includes
One pedestal matrix 11, the first arc groove 16 being located on the first pedestal matrix 11, be located on the first arc groove 16 first
Center pillar 14, the power lug connector 15 being located on the first center pillar 14 upper surface；Second pedestal 2 include the second pedestal matrix 21,
The second arc groove 25 of being located on the second pedestal matrix 21, it is located on the second arc groove 25 and matches with the first center pillar 14
Second center pillar 24；It is provided with the first cooling pipe 13 for cooling bottom first pedestal 1, is provided with for cold bottom the second pedestal 2
But the second cooling pipe 23.First center pillar 14 is one-body molded with the first pedestal matrix 11, the second center pillar 24 and the second pedestal base
Body 21 is one-body molded, so facilitates the processing of transformer base and ensures transformator stability in use and safety
Property.
First center pillar 14 is semicylinder, and the second center pillar 24 is the semicylinder matched with the first center pillar 14, this sample prescription
Just iron core and the installation of primary side winding.Power lug connector 15 includes cylinder and is arranged on power lug connector 15 lower end
The projection matched with the first center pillar 14 on face, projection is that the semicylinder equal with cylinder diameter, cylinder and projection are adopted
With the integral forming process of convenient processing, make cylindrical lower surface higher than the second center pillar 24 by projection, it is ensured that power lug
Connector does not directly contact with the second center pillar.The type of cooling of general transformator is all at the first pedestal 1 and the second pedestal 2
Side opening is provided with water-cooled or oily cold pipeline, the heat radiation in the middle of transformer bottom so can be caused bad, cause local temperature
Too high, easily cause the damage of transformator, the first cooling pipe 13 and the second cooling pipe 23 that the present invention offers are positioned at transformation
Centre bottom device pedestal, in use can make cooling rapidly in the middle of transformer bottom, improve the service life of transformator.
First cooling pipe 13 is connected by Petrochemical Pipe Joints with the second cooling pipe 23, the first cooling pipe 13 and second
Cooling pipe 23 is respectively through the first pedestal 1 and through hole of the second pedestal 2, and transformer bottom so can be made to cool down more
Fully, by Petrochemical Pipe Joints connection can regular check the first cooling pipe 13 and the stopping state of the second cooling pipe 13, guarantor
Hinder the properly functioning of cooling system.Certainly, the first cooling pipe 13 and the second cooling pipe 23 can be according to actual service conditions
It is designed to single cooling pipe；Or do not use Petrochemical Pipe Joints, and be made as and the 3rd cooling pipe 12 and the 4th cooling
The design of pipeline 22, specifically can refer to the U-shaped pipe design of the 4th cooling pipe 22 of Fig. 4, and is not limited to be preferable to carry out
In example by pipe joint connect with the use of.
Power lug connector 15 is detachably connected on the first center pillar 14 by hexagon socket head cap screw, passes through hexagon socket head cap screw
Fixing bolt head can be avoided to protrude cause bad impact, certainly, the connected mode of power lug connector also can use tack
Other non-bulging next connectors such as bolt connection connect, and the hexagon socket head cap screw being not limited in preferred embodiment connects.
First pedestal 1 left surface is provided with the 3rd cooling pipe 12, and the second pedestal 2 right flank is provided with the 4th cooling pipe 22.
4th cooling pipe 22 is U-shaped shape inside the second pedestal 2, and it is by the inlet being located on side and a liquid mouth of a river
Cool down, be specifically shown in Fig. 4.3rd cooling pipe 12 portion in First body is U-shaped shape, and it is by be located on side one
Inlet and a liquid mouth of a river cool down, and specifically refer to the design of the 4th cooling pipe 22, by the 3rd cooling duct 12
With the temperature that the 4th cooling duct 22 can reduce transformator both sides, prevent temperature too high damage transformator.
It is provided with insulating trip between first pedestal 1 and the second pedestal 2, prevents the first pedestal 1 and the second pedestal 2 by insulating trip
Directly contact, ensures the normal use of transformator.
First arc groove 16 and the second arc groove 25 cooperatively form the storage tank of accommodating iron core and primary side winding, and first
Arc groove 16 is all the groove that radius is identical with the second arc groove 25, so facilitates joining of the first pedestal and the second pedestal
Closing, be also convenient for the installation of iron core and primary side winding, certainly, the shape of the first arc groove 16 and the second arc groove 25 can basis
Actual needs makes corresponding change so that it is adapt to the use requirement of transformator.
In sum, the present invention, on the basis of traditional transformer, adds an air-cooled pedestal to iron core, this pedestal four
There is air channel in week, walks heat by blower fan cooling zone.Add the safeguard procedures of traditional transformer, increase the service life, preferably
Solve heat dissipation problem, it is adaptable to more severe corrosive gas, the hydropenia environment of corrosivity dust.By at the first center pillar
Dismountable power lug connector is set on upper surface, surface area can be increased, improve the output of electric current, can be simultaneously connected with again
More lug.By the first cooling pipe offered respectively with the second pedestal base bottom the first pedestal and the second cooling
Pipeline, the radiating effect making transformator is more preferable, improves the service life of transformator, the simple in construction of the present invention and need not be additional
Chiller just can solve the problem that transformator cost of manufacture is high.
The foregoing is only the preferred embodiments of the present invention, the present invention is not limited to above-mentioned embodiment, as long as with
Essentially identical means realize within the technical scheme of the object of the invention broadly falls into protection scope of the present invention.
