Description

A kind of air water cooling but dry-type transformer cabinet wind path structure
Technical field
The utility model relates to the but dry-type transformer cabinet wind path structure design of a kind of air water cooling, belongs to transformer technology field.
Background technology
Along with the increase of dry-type transformer capacity, air water cooling but dry-type transformer by more and more many application.Identical capacity, air water cooling but the general transformer of transformer ratio to have volume little, empty calory distributes and can in advantages such as the higher applications of volume requirement, environmental requirement.Particularly in warship cabin, adopt air water cooling but dry-type transformer, can conserve space, and without cabin heat dissipation problem.
For air water cooling dry-type transformer cabinet but, its cooling effectiveness decides volume and the capacity of cooling device.When cooling effectiveness height, the cooling blower in cooling device and cooling heat exchanger just can be raised the efficiency, and reduce cooling blower volume and power, and then reduce volume and the airborne noise of whole dry-type transformer cabinet.Therefore, the design of dry-type transformer cabinet wind path is the key technology of Cooling Design.
Summary of the invention
The technical problems to be solved in the utility model improves the cooling effectiveness of air water cooling dry-type transformer cabinet but.
In order to solve the problems of the technologies described above, the technical solution of the utility model there is provided a kind of air water cooling but dry-type transformer cabinet wind path structure, comprise cabinet, cabinet is provided with the blower fan system forming vertical direction flowing wind for the space in cabinet, iron core is provided with in cabinet, iron core is enclosed with three low pressure windings respectively, a high pressure winding is enclosed with outward respectively at each low pressure winding, it is characterized in that: in cabinet, be provided with guide plate, by guide plate, the space in cabinet is divided into upper room and lower room, guide plate has three air-guiding holes, three high voltage winding groups are passed respectively thus form wind-guiding gap between the outer circumference surface of each high pressure winding and the inwalls of corresponding air-guiding hole in three air-guiding holes.
Preferably, described guide plate is positioned at 1/2 position of described high pressure winding height, and the width in described wind-guiding gap is suitable with the chimney width of described low pressure winding.
Preferably, described blower fan system comprises the air outlet being positioned at position, described upper room and the air inlet being positioned at position, described lower room, and air outlet is provided with blower fan.
Transformer case is separated by the utility model, forms directed air path system.This structure can improve transformer Cooling efficiency, has again structure simple, is easy to the advantage realized.Can effectively solve air water cooling but in dry-type transformer cabinet dry-type transformer winding to dispel the heat problem pockety and the low problem of cooling effectiveness.
The utility model has the advantages that: can cooling effectiveness be improved, reduce the dry-type transformer three-phase windings temperature difference, reduce power and the heat exchanger area of centrifugal blower, thus reduce dry-type transformer cabinet sum airborne noise.

Embodiment
For making the utility model become apparent, hereby with preferred embodiment, and accompanying drawing is coordinated to be described in detail below.
As shown in Figure 1, a kind of air water cooling that the utility model provides but dry-type transformer cabinet wind path structure comprises cabinet 3, is provided with iron core 2 in cabinet 3, composition graphs 3, iron core 2 is enclosed with three low pressure windings 8 respectively, outside each low pressure winding 8, is enclosed with a high pressure winding 1 respectively.
In cabinet 3, be also provided with guide plate 4, guide plate 4 is positioned at 1/2 position of high pressure winding 1 height, by guide plate 4, the space in cabinet 3 is divided into upper room and two, lower room part.Composition graphs 2, guide plate 4 has three air-guiding holes, three high pressure windings 1 pass respectively thus form wind-guiding gap between the outer circumference surface of each high pressure winding 1 and the inwalls of corresponding air-guiding hole in three air-guiding holes, the width in this wind-guiding gap is suitable with the chimney width of low pressure winding 8, elects 10mm as in the present embodiment.
Be provided with air outlet 5 in the position, upper room of cabinet 3, this air outlet 5 is provided with blower fan 6, this blower fan 6 is air draught type.Air inlet 7 is provided with in the position, lower room of cabinet 3.
Although the utility model describes with reference to the above embodiments; but those of ordinary skill in the art; will be appreciated that above embodiment is only used to the utility model is described; should understand and wherein can make various changes and revise and not depart from the utility model in a broad sense; so be not that conduct is to restriction of the present utility model; as long as in spirit of the present utility model, all the protection range of the utility model claim will be fallen into the change of above-described embodiment, distortion.
