Abstract

The utility model discloses a vertical-typed voltage withstand transformer bobbin which comprises a bobbin body, a winding groove, a left stand, a right stand, primary pins and secondary pins, wherein the winding groove is arranged on the upper end of the bobbin body, a magnetic core hole is arranged in the winding groove, the primary pins are arranged under the left stand, and the secondary pins are arranged under the right stand. The vertical-typed voltage withstand transformer bobbin is characterized in that five primary pins and four secondary pins are provided, the primary pins are correspondingly provided with primary coil out grooves, the secondary pins are correspondingly provided with secondary coil out grooves, and the edge of the upper portion of the right stand is provided with a dam board. The vertical-typed voltage withstand transformer bobbin has the advantages that the primary coil out grooves are respectively provided with a coil and a groove, accordingly the possible winding problem among each winding is avoided, the insulation distance is increased, and the voltage withstand problem is solved; the secondary sides are respectively provided with a coil and a groove as well, thereby increasing the insulation distance between the primary sides and the secondary sides, so that the use of the insulation casing is canceled, production process is simplified, and production efficiency is improved.

Description

The withstand voltage skeleton of a kind of transformer vertical-type

Technical field

The utility model relates to Transformer skeleton technical field, particularly a kind of vertical withstand voltage skeleton of multiple groove that is applicable to transformer and can satisfies the requirement of Automated winding production fully.

Background technology

The structure of at present general EE16-V vertical transformer skeleton mainly contains end Tong, File wall, stitch and pin base and consists of, because elementary line arrives secondary stitch distance not, need wrap multilayer tape and cover insulating sleeve during production, increase the difficulty of operation and affected production efficiency, can not satisfy the requirement that Automated winding is produced fully, and elementary coiling and secondary rolling thread can not be accomplished a line one groove, can not satisfy the requirement of withstand voltage more than the 2KV when the input and output of many windings.

Summary of the invention

The utility model provides a kind of above skeleton of the vertical withstand voltage 2KV of multiple groove that is applicable to transformer and can satisfies the requirement of Automated winding production fully.

For the problem of mentioning above solving, reach the purpose of expection, the utility model has adopted following scheme: the withstand voltage skeleton of a kind of transformer vertical-type, comprise the skeleton body, winding slot, the left foot frame, the right crus of diaphragm frame, elementary stitch, secondary stitch, described winding slot is positioned at skeleton body upper end, be provided with the magnetic core hole in the winding slot, left foot frame and right crus of diaphragm frame are in skeleton body both sides, elementary stitch is arranged under the left foot frame, secondary stitch is arranged under the right crus of diaphragm frame, it is characterized in that: described elementary stitch is five, secondary stitch is four, and described elementary stitch correspondence is provided with elementary line outlet groove, and secondary stitch correspondence is provided with secondary line outlet groove, described right crus of diaphragm frame top edges is provided with plate washer, and plate washer has increased the distance of iron core to primary side.For convenient coiling prevents the scratch copper cash, elementary line outlet groove, secondary line outlet groove, coiling trough rim are provided with fillet.

Owing to adopted above technical scheme, the beneficial effects of the utility model are: elementary line outlet groove is a line one groove, has avoided between each winding issuable winding problem to increase insulation distance and has solved problem of withstand voltage.Primary side also is a line one groove, has increased the insulation distance between primary and secondary, thereby production process has been simplified in the use of cancellation insulating sleeve, has improved production efficiency.
