Abstract
The transformator spiral type cooling air channel of a kind of transformer Cooling, is made up of coil body, air channel structure body and air channel, and air channel structure body spiral is arranged in the middle of loop construction body.When using this utility model, the cooling wind of blower fan is blown into coil helix shape cooling air channel, by spreading all over the interior omnibearing air channel of first circle, for coil effective temperature-reducing, it is possible to meet the demand of whole coil body effective temperature-reducings when transformator runs.
Description
Technical field
A kind of transformator spiral type cooling air channel of transformer Cooling.
Background technology
Because load loss and other added losses in transformator work process, heat can be produced.If effectively do not dispelled the heat the heat produced in transformator work process, transformer coil can be because temperature be high, and insulating paper aging speed is fast, and dielectric strength step-down makes transformator not reach requirement in service life, even burns transformator.
In order to effectively reduce the operating temperature of transformer coil, former transformator, in the middle of loop construction body, it is provided with cooling air channel.In the past, being arranged on the cooling air channel in the middle of transformer coil structure body is axial ducts version straight up and down.Although the cooling air channel of this version can play a certain degree of cooling effect, but, because wherein part air channel is affected by iron yoke position, cooling wind is difficult to enter above-mentioned air channel, greatly reduce the cooling usefulness of cooling air channel, make the coil temperature the being blocked position temperature far above other positions of coil, affect coil global design performance indications, it is impossible to meet the demand of effective temperature-reducing when transformator runs.
Summary of the invention
The purpose of this utility model is the design by spiral type cooling air channel so that transformer coil air channel spiral is through in the middle of loop construction body, and cooling wind energy is enough by spiral type cooling air channel, effectively carries out wind cooling temperature lowering for loop construction body is comprehensive.
This utility model is made up of coil body, air channel structure body and air channel, and air channel structure body spiral is arranged in the middle of loop construction body.
Air channel structure body uses elastomeric material, is supported in the middle of loop construction body.
Iron yoke blocking position does not set tunnel inlet, and tunnel inlet is arranged on iron yoke two side position.
When using this utility model, the cooling wind of blower fan is blown into coil helix shape cooling air channel, by air channel omnibearing in spreading all over coil, for coil effective temperature-reducing, it is possible to meet the demand of whole coil body effective temperature-reducings when transformator runs.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model, is also specification digest figure.Accompanying drawing 2 is top view of the present utility model.In figure, each label is respectively: (1) blower fan, (2) coil body, (3) air channel structure body, (4) air channel.
Detailed description of the invention
Provide an example in conjunction with accompanying drawing this utility model is described further.
Embodiment
Blower fan 1 is device outside, and it is 180mm that coil body 2 cross section is formed semicircular inside radius a size of 120mm outer radial dimension by two semicircles and a rectangle, and a length of 150mm of cuboid, coil body height is 600mm；The size of air channel structure body 3 is the elastomeric material of diameter 12mm；Air channel 4 width is 50mm, and spiral angle is 20 degree.
