Description
Technical Field
The utility model relates to a dry-type grounding transformer coil technical field provides a high-pressure foil is around dry-type grounding transformer coil very much.
Background
At present, a known dry-type grounding transformer high-voltage coil adopts a wire winding structure, the internal insulation of the coil comprises wire turn insulation, the insulation ratio is high, the wire winding needs manual winding, the procedures of climbing layers, insulation wrapping and the like are needed in the winding process, and the winding efficiency of the coil is low.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model provides a high-pressure foil is around dry-type grounding transformer coil.
The utility model discloses a realize like this, a high-pressure foil is around dry-type grounding transformer coil, adopt the foil to wind the structure, including 3I sections of coil and 3 II sections of coil, I sections of coil and II sections alternate arrangement of coil, 3I sections of coil are connected in order through I sections of coil, and be equipped with I sections leading-out terminal of coil on first I section of coil and the I section of third coil respectively, 3 II sections of coil are connected in order through II sections of coil, and be equipped with II sections leading-out terminal of coil on first II sections of coil and the II sections of third coil respectively, it is insulating to set up the section between adjacent I sections of coil and coil, the outside is equipped with the end and insulates.
Preferably, the coil i-section outlet terminals are respectively an outlet terminal a1 and an outlet terminal X1, and the coil ii-section outlet terminals are respectively an outlet terminal a2 and an outlet terminal X2.
Compared with the prior art, the utility model has the advantages of:
the dry-type grounding transformer high-voltage coil adopts a foil winding structure, so that the material cost can be effectively saved, the coil winding efficiency is improved, the structure is simple, and the operation is convenient.
Drawings
The present invention will be described in further detail with reference to the accompanying drawings and embodiments:
FIG. 1 is a schematic sectional view of the present invention;
fig. 2 is an appearance schematic diagram of the present invention.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1 and 2, the utility model provides a high-pressure foil is around dry-type grounding transformer coil, adopt the foil to wind the structure, including I section 1 of 3 individual coils and II sections 2 of 3 individual coils, I section 1 of coil and II section 2 alternate arrangement of coil, I section 1 of 3 individual coils connects 3 in order through I section intersegmental connection of coil, and be equipped with I section leading-out terminal 4 of coil on I section 1 of first coil and I section 1 of third coil respectively, II section 2 of 3 individual coils connect 5 in order through II intersegmental connections of coil, and be equipped with II section leading-out terminal 6 of coil on II section 2 of first coil and II section 2 of third coil respectively, set up intersegmental insulation 7 between I section 1 of adjacent coil and II section 2 of coil, the outside is equipped with end insulation 8. The inter-stage insulation 7 and the end insulation 8 are formed by pouring an insulating resin after the coil winding is completed.
In the coil provided by the utility model, the coil sections are arranged in a staggered way from top to bottom, and because the foil has no wire turn insulation and only has interlayer insulation, the insulation ratio is low, and the material cost is saved; and the foil winding structure adopts automatic equipment for winding, so that the winding efficiency is greatly improved.
Specifically, the coil i-section outlet terminal 4 is an outlet terminal a1 and an outlet terminal X1, and the coil ii-section outlet terminal 6 is an outlet terminal a2 and an outlet terminal X2.
An end insulation 7 is provided on the outside of the transformer coil.
The embodiments of the present invention have been described in detail with reference to the drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art.
