Abstract
The invention discloses a transformer body insulation structure. The transformer body insulation structure comprises a low-voltage coil and a high-voltage coil, wherein the low-voltage coil is sleeved with the high-voltage coil, upper iron yoke insulation parts are arranged at the top of the low-voltage coil and the top of the high-voltage coil, lower iron yoke insulation parts are arranged at the bottom of the low-voltage coil and the bottom of the high-voltage coil, and iron yoke partition plates are arranged on the end faces of the upper iron yoke insulation parts and the end faces of the lower iron yoke insulation parts. According to a transformer body of the structure, due to the fact that the iron yoke insulation parts are arranged at the top and the bottom of the high-voltage coil and the top and the bottom of the low-voltage coil, the transformer body is good in insulation performance, reliable in electrical performance, small in size, high in strength and convenient to produce and manufacture.
Description
Technical field
The present invention relates to field transformer, particularly a kind of device body insulation structure of transformer.
Background technology
Transformer in electrical power distribution system is more and more at present.Loss is low, environment-friendly type, product that volume is little are more and more favored.And the little product that must cause of volume will adopt the version of the little insulation distance of high-voltage coil and low-voltage coil in manufacturing and designing, if therefore adopt traditional insulation system form, insulation processing between high-low pressure is bad, by directly affecting running quality and the useful life of transformer, to user, bring loss.
Summary of the invention
The object of the present invention is to provide and a kind ofly can strengthen electric insulation intensity, dependable performance, the device body insulation structure of the transformer of long service life.
Technical scheme of the present invention is as follows:
A kind of device body insulation structure of transformer, comprise low-voltage coil and be enclosed within the high-tension coil outside low-voltage coil, the top of described low-voltage coil and high-tension coil is provided with upper yoke insulation division, the bottom of described low-voltage coil and high-tension coil is provided with lower yoke insulation division, and the end face of described upper yoke insulation division and lower yoke insulation division is provided with iron yoke dividing plate.
Useful technique effect of the present invention is:
Transformer body of the present invention arranges core insulation portion by the top at high-tension coil and low-voltage coil and bottom, thereby makes the good insulation preformance of transformer body, and electric property is reliable, and volume is little, intensity is high, and it is convenient to manufacture.
Advantage of the present invention will provide in embodiment description partly below, and part will become obviously from the following description, or recognize by practice of the present invention.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described further.
As shown in Figure 1, the present invention includes the low-voltage coil 2(LV being wound on outside middle iron core) and be enclosed within the high-tension coil 3(HV outside low-voltage coil 2).The top of low-voltage coil 2 and high-tension coil 3 is provided with upper yoke insulation division 1, and the bottom of low-voltage coil 2 and high-tension coil 3 is provided with lower yoke insulation division 4.On low-voltage coil 2 perforate with draw screw rod colligation, make iron yoke and coil compression.The end face of upper yoke insulation division 1 and lower yoke insulation division 4 is provided with iron yoke dividing plate 5.
Above-described is only the preferred embodiment of the present invention, the invention is not restricted to above embodiment.Be appreciated that the oher improvements and changes that those skilled in the art directly derive or associate without departing from the basic idea of the present invention, within all should thinking and being included in protection scope of the present invention.
