Description
Technical field
The utility model belongs to the transformer technology field, specifically, and particularly a kind of dry-type transformer coil coiling mould.
Background technology
At present, the winding former of dry-type transformer has a variety of, and wherein the mould of oval coil majority is straight ellipse shape.Straight ellipse shape mould is that a cylinder is divided into two semicircles, connects straight plate between two semicircles, and the mould of this structure coil around straight plate part part when coiling arches upward easily, makes the size of coil be difficult to control, finally influences the performance parameter of transformer.And in the junction of semicircle with straight plate, the coil bending internal stress is bigger, not only damages the insulating barrier on the coil easily, and coil internal stress skewness, and the electric property of coil is caused certain influence.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of oval-shaped dry-type transformer coiling mould.
The technical solution of the utility model is as follows: a kind of dry-type transformer coil coiling mould, it is characterized in that: the winding section and the end plate (3) that covers at the two ends, winding section that comprise oval tubular, wherein the winding section is formed by the butt joint of laterally zygomorphic two and half ellipse shape templates (1), the opening end of described template (1) bends inwards and forms flange (1a), in the winding section, be provided with anchorage clip (4), described anchorage clip (4) is flute profile, the flange (1a) of two templates (1) all snaps in the groove of anchorage clip (4), between the groove side plate of described flange (1a) and anchorage clip (4), be lined with strip square steel (5), between the flange (1a) of two templates (1), be lined with sealing strip (6).
Adopt said structure, the winding section is designed to by the oval tubulars of two template butt joints up and down, and two templates are fastening by anchorage clip, sealing strip and square steel up and down, thereby provide a kind of pure oval-shaped dry-type transformer coil coiling mould, make the coil of coiling be standard oval, avoided original straight ellipse shape coiling mould coil to arch upward and coil internal stress problem of uneven distribution, made coil winding convenient, electric property is more stable.And the assembly and disassembly of winding section are all very convenient.
In the outside of described end plate (3) bar shaped block (2) is arranged fixedly, the outer surface welding of one end of described block (2) and end plate (3), the other end of block (2) stretches out the winding section, in described winding section, be installed with screw rod (7), corresponding end plate (3) is run through at the two ends of described screw rod (7), is with nut (8) in the termination of screw rod (7).Cooperate by block, screw rod and nut like this, end plate is covered two ends in the winding section, thus fixing entire die, and not only the fixed structure of end plate is simple; And end plate can dismantle easily, makes the two ends of winding section that location-plate can directly be installed, thereby makes the winding section except being used for coiling, also can be used as the cast internal mold of coil, further saved production equipment, reduced production operation, reduced production cost; Moreover block can also prevent the wire turn landing of end winding when coiling, cause coil slack and undisciplined.
Be placed with interior fagging (9) in described winding section, described interior fagging (9) is perpendicular with the center line of winding section, and the peripheral profile of interior fagging (9) and the inner surface of winding section coincide, and fagging can be strengthened the intensity of winding section in arranging.
Middle at described end plate (3) and interior fagging (9) has square hole, and the center line of all square holes conveniently penetrates the coiling arbor point-blank.
Beneficial effect: the winding section of the utility model by mould that dry-type transformer coil is wound the line is designed to by the oval tubular of two templates to being connected into up and down, thereby provide a kind of pure oval-shaped dry-type transformer coil coiling mould, arch upward when having avoided coil winding and the internal stress skewness, make the coil of coiling be standard oval, have be skillfully constructed, simple in structure, produce easily and characteristics such as production cost is low.
