The utility model provides a high voltage coil's insulating cylinder structure, it is including installing in the outside insulating cylinder of high voltage coil, the insulating cylinder outside is provided with heat dissipation wind channel structure, and the upper and lower tip of heat dissipation wind channel structure all is provided with insulating end circle, and insulating cylinder and insulating end circle are not on a plane, and the upper end of insulating cylinder has the last extension that exceeds heat dissipation wind channel structure top insulating end circle, and the lower tip of insulating cylinder has the lower extension that surpasss heat dissipation wind channel structure bottom insulating end circle. The utility model provides a high tension coil's insulating cylinder structure is owing to all set up the extension that one end surpassed insulating end circle with the upper and lower tip of insulating cylinder to can effectual increase creepage distance, so then can reduce high tension coil to the main control of iron core says insulating distance, effectual reduction holistic volume can also reduce the cost of product.

Description

Insulating cylinder structure of high-voltage coil

Technical Field

The utility model relates to a transformer field especially relates to a high tension coil's insulating cylinder structure.

Background

The high-voltage coil outside of transformer need arrange a high-voltage tube, because the security is considered, high-voltage tube and high-voltage coil's distance is great, and then causes the outside heat radiation structure external diameter of high-voltage tube also great (heat radiation structure's upper and lower tip all is provided with insulating end ring, and the upper and lower tip of high-voltage tube flushes with the insulating end ring of heat radiation structure installation), so then causes overall structure bulky, with high costs.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a high-tension coil's insulating cylinder structure, its volume that can reduce the outside heat radiation structure of high-tension coil reduces whole manufacturing cost.

The utility model provides a pair of high tension coil's insulating cylinder structure, it is including installing in the outside insulating cylinder of high tension coil, the insulating cylinder outside is provided with heat dissipation wind channel structure, and the upper and lower tip of heat dissipation wind channel structure all is provided with insulating end circle, and insulating cylinder and insulating end circle are not on a plane, and the upper end of insulating cylinder has the last extension that exceeds heat dissipation wind channel structure top insulating end circle, and the lower tip of insulating cylinder has the lower extension that surpasss heat dissipation wind channel structure bottom insulating end circle.

Compared with the prior art, the utility model provides a high tension coil's insulating cylinder structure is owing to all set up the extension that one end surpassed insulating end circle with the upper and lower tip of insulating cylinder to can effectual increase creepage distance, so then can reduce high tension coil to the main control of iron core way insulation distance, the holistic volume of effectual reduction can also reduce the cost of product.

Further, go up the extension, the size of extension down is 20mm, and under the condition that the upper and lower tip of insulating cylinder all exceeds insulating end ring 20mm, creepage distance can increase 40mm, so can reduce 5mm with the wind channel interval to reduce the whole size of product.

Further, go up extension, lower extension and insulating cylinder integrated into one piece, of course, can also adopt assembled structure between extension and lower extension and the insulating cylinder, for example, set up annular embedding recess at the upper and lower end of insulating cylinder, set up at extension and lower extension and annular embedding arch with annular embedding recess complex, consider the stability of extension installation down, can set up the elastomer of the tight fit installation of being convenient for, for example, elastic rubber at the internal surface or the surface of extension down to can let the extension tight fit installation of down take one's place. The heights of the upper and lower extensions can be adjusted by the assembly structure.

Further, the upper extension is coaxially arranged with the insulating cylinder.

Further, the lower extension is arranged coaxially with the insulating cylinder.

Further, the upper and lower extensions have the same wall thickness as the insulating cylinder.

Detailed Description

The present invention will now be described in more detail with reference to the drawings, in which preferred embodiments of the invention are shown, it being understood that one skilled in the art could modify the invention herein described while still achieving the beneficial effects of the invention. Accordingly, the following description should be construed as broadly as possible to those skilled in the art and not as limiting the invention.

As shown in fig. 1-2, the utility model discloses a high voltage coil's insulating cylinder structure, it is including installing in the outside insulating cylinder 1 of high voltage coil, this insulating cylinder is the cylinder, the inner space of insulating cylinder then is used for installing high voltage coil, the insulating cylinder outside is provided with heat dissipation wind channel structure 2, the upper and lower tip of heat dissipation wind channel structure all is provided with insulating end ring 3, insulating cylinder and insulating end ring are not on a plane, the upper end of insulating cylinder has the last extension 4 that exceeds heat dissipation wind channel structure top insulating end ring, the lower tip of insulating cylinder has lower extension 5 that surpasss heat dissipation wind channel structure bottom insulating end ring.

In this embodiment, the size of going up extension, extension down is 20mm, and under the condition that the upper and lower tip of insulating cylinder all exceeds insulating end circle 20mm, creepage distance can increase 40mm, so can reduce 5mm with the wind channel interval to reduce the whole size of product.

This high voltage coil's insulating cylinder structure is owing to all set up the extension that one end surpassed insulating end circle with the upper and lower tip of insulating cylinder to can effectual increase creepage distance, so then can reduce high voltage coil to the main control of iron core says insulating distance, effectual reduction holistic volume, can also reduce the cost of product.

In this embodiment, the upper and lower extensions are coaxially arranged with the insulating cylinder, and the upper and lower extensions have the same wall thickness as the insulating cylinder, and the upper and lower extensions may be integrally formed with the insulating cylinder main body.

The above description is only for the preferred embodiment of the present invention, and does not limit the present invention. Any technical personnel who belongs to the technical field, in the scope that does not deviate from the technical scheme of the utility model, to the technical scheme and the technical content that the utility model discloses expose do the change such as the equivalent replacement of any form or modification, all belong to the content that does not break away from the technical scheme of the utility model, still belong to within the scope of protection of the utility model.
