Abstract
The utility model relates to a segmental casting assembled coil. The segmental casting assembled coil comprises a coil and lead-out ends and is characterized in that the coil is assembled by an upper half coil and a lower half coil by a connecting component; a plurality of lead-out ends are arranged at the same side of the upper half coil and the lower half coil respectively; the connecting component is a pinhole structure; a hole is arranged at the lower end of the upper half coil; a pin matched with the hole is arranged at the upper end of the lower half coil; the hole is a conical hole; and the pin is a conical pin. As the coil is combined by two segments, the segmental casting assembled coil frees from limitations on the height of a casting instrument or the height of a coil mould, and the requirement of the product on the height is met.
Description
Technical field
The utility model relates to a kind of step pouring assembly type coil, is applicable to dry-type transformer.
Background technology
With respect to oily formula transformer, dry-type transformer so the iron core of dry-type transformer and coil are not immersed in the insulating oil, does not just have problems such as fire, blast, pollution because of there not being oil yet.The coil (as shown in Figure 1) of dry-type transformer receives the restriction of casting equipment height, coil die height and can't satisfy the product design needs at present, so be necessary to invent a kind of step pouring assembly type coil.
Summary of the invention
In view of the deficiency of prior art, the technical scheme purpose of the utility model is to provide a kind of step pouring assembly type coil that does not receive casting equipment height, coil die limitation in height, satisfies the needed height of product design.
To achieve these goals; The technical scheme of the utility model is: a kind of step pouring assembly type coil; Comprise coil and leading-out terminal; It is characterized in that: said coil is assembled through coupling assembling by upper semisection coil and lower semisection coil, and the same side of said upper semisection coil and lower semisection coil is equipped with a plurality of leading-out terminals.
Further, said coupling assembling is the hole latch structure.
Further, the lower end of said upper semisection coil is provided with the hole, and the upper end of said lower semisection coil is provided with the pin that matches with the hole; Perhaps, the lower end of said upper semisection coil is provided with pin, and the upper end of said lower semisection coil is provided with the hole of matching with pin.
Further, said hole is a conical bore, and said pin is a taper bolt; Perhaps, said hole is a cylindrical hole, and said pin is a straight pin.
Compared with prior art, the utlity model has following advantage: this coil is assembled by upper semisection coil and lower semisection coil, so do not receive casting equipment height, coil die limitation in height, satisfies the needed height of product design.
Description of drawings
Fig. 1 is the cross-sectional schematic of existing coil.
Fig. 2 is the cross-sectional schematic of the utility model embodiment.
Among the figure: 1-coil 1-1-upper semisection coil 1-2-lower semisection coil 2-leading-out terminal 3-coupling assembling.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further explanation.
With reference to figure 2; A kind of step pouring assembly type coil; Comprise coil 1 and leading-out terminal 2; It is characterized in that: said coil 1 is assembled through coupling assembling 3 by upper semisection coil 1-1 and lower semisection coil 1-2, and the same side of said upper semisection coil 1-1 and lower semisection coil 1-2 is equipped with a plurality of leading-out terminals 2.The utility model is divided into two the coil that script need water to one, and coil assembles to reach the design height of coil through behind the step pouring again.
In the present embodiment, said coupling assembling 3 is the hole latch structure, can also be other syndeton certainly, is not limited to this.
In the present embodiment; The lower end of said upper semisection coil 1-1 is provided with the hole; When cast, just reserve and portal, the upper end of said lower semisection coil 1-2 is provided with the pin that matches with the hole, when coil winding; Pour into a mould with lower semisection coil 1-2 the upper end that needs pin to be embedded in lower semisection coil 1-2, to guarantee mechanical strength; Can certainly be, the lower end of said upper semisection coil 1-1 be provided with pin, and the upper end of said lower semisection coil 1-2 is provided with the hole of matching with pin.
In the present embodiment; Said hole is a conical bore, and said upper semisection coil 1-1 can be evenly equipped with six conical bores, and said pin is a taper bolt; Said lower semisection coil 1-2 can be evenly equipped with six corresponding taper bolts, makes things convenient for the assembling of upper semisection coil 1-1 and lower semisection coil 1-2; Can certainly be, said hole be a cylindrical hole, and said pin is a straight pin, but is not limited to this.
In the present embodiment; Said coil 1 is a drum type brake, can adopt the glass fiber reinforced epoxy resin cast, can prevent the resin cracks of pouring into a mould effectively; The reliability of raising equipment; But be not limited to this, can also adopt the other materials cast, for example adopt epoxy resin to add quartz sand and fill methods such as cast.
Watering in the injection molding design, taking into full account the design demand of above-mentioned coil.Design at first, respectively that die cavity is identical with upper and lower half section coil shape, two pairs of consistent size water injection molding; Secondly, water at the upper semisection coil of design and to add six cone axis (being uniformly distributed with) on the injection molding bottom end cover, make the lower end of the upper semisection formed coil after the cast that six moulding conical bores arranged; Its three, water on the injection molding upper end cover at the lower semisection coil of design and to add six conical sleeves (being uniformly distributed with), make the upper end of the lower semisection formed coil after the cast that six moulding taper bolts arranged; Its four, for guaranteeing the quality of fit of conical sleeve and conical bore,, the upper semisection coil watered six cone axis water six conical sleeves on the injection molding upper end cover with the lower semisection coil on the injection molding bottom end cover in die manufacture, require the scene of implementing to prepare.
The above is merely the preferred embodiment of the utility model, and all equalizations of being done according to the utility model claim change and modify, and all should belong to the covering scope of the utility model.
