Abstract
The utility model discloses a pouring type voltage transformer body and belongs to the technical field of voltage transformers. The pouring type voltage transformer body comprises a primary coil (1), a secondary coil (2) and an iron core (3). The secondary coil (2) winds the iron core (3). The primary coil (1) penetrates the window of the iron core (3). The pouring type voltage transformer body further comprises a support part (4) and a positioning plate (5). The support part (4) is fixed outside the primary coil (1) and fixedly connected with a die. The outgoing line of the primary coil (1) is welded to the support part (4). The positioning plate (5) is fixed at the bottom of the iron core (3) and fixedly connected with the base plate of the die. The pouring type voltage transformer body has the advantages that when the pouring type voltage transformer body is used for die filling, due to the fact that the primary coil and the secondary coil are fixed respectively, only one kind of insulating material is directly poured into the die for curing and forming, and due to the fact that only one kind of insulating material is used, good insulating performance is achieved.
Description
Technical field
The utility model relates to a kind of casting type voltage mutual inductor device body, belongs to voltage transformer technical field.
Background technology
Existing casting type voltage mutual inductor device body is normally made up of primary winding, secondary coil, iron core, make primary winding and secondary coil location by fill in resin mass or insulating board between primary winding shielding cylinder and secondary coil, when dress mould, a lead terminal is received to water in outlet newel post of injection molding and is drawn.Need to jump a queue between primary winding and secondary coil resin mass or cardboard of this machine body structure positions, and resin mass fineness and cleannes required high especially, cardboard is also required to dry cleansing, and operation easier is larger; Meanwhile, owing to there being different dielectrics, between primary winding and secondary coil, inner bubble and the crack of easily producing of main insulation, causes insulation property not good.
Summary of the invention
The problem existing for above-mentioned prior art, the utility model provides a kind of casting type voltage mutual inductor device body, realizes primary winding and secondary coil fixing respectively, ensures a kind of dielectric of cast, and then improves the insulation property of product.
To achieve these goals, the technical solution adopted in the utility model is: a kind of casting type voltage mutual inductor device body, comprise primary winding, secondary coil and iron core, secondary coil is wound on iron core, primary winding, through core window, also comprises supporter and location-plate, and supporter is fixed on outside primary winding and is fixedly connected with mould, primary winding lead-out wire is welded on supporter, and location-plate plate is fixed on iron core bottom and is fixedly connected with die bottom plate.
Preferably, described supporter is wrapped up in primary winding outside with bandage.
Preferably, described location-plate is fixed on iron core bottom with bandage wrapping.
Preferably, described location-plate is fixedly connected with die bottom plate by screw bolt and nut.
The beneficial effects of the utility model are: while adopting this device to fill mould, owing to respectively primary winding and secondary coil being fixed, in the time of cast, only need to adopt a kind of insulating material to be directly poured into curing molding in mould, owing to only using a kind of insulating material, insulation property are better.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1: the utility model comprises primary winding 1, secondary coil 2 and iron core 3, secondary coil 2 is wound on iron core 3, primary winding 1 is through iron core 3 windows, also comprise supporter 4 and location-plate 5, supporter 4 is fixed on outside primary winding 1 and is fixedly connected with mould, primary winding 1 lead-out wire is welded on supporter 4, and location-plate 5 plates are fixed on iron core 3 bottoms and are fixedly connected with die bottom plate.
Supporter 4 use bandages are wrapped up in primary winding 1 outside; Location-plate 5 use bandage wrappings are fixed on iron core 3 bottoms; Described location-plate 5 is fixedly connected with die bottom plate by screw bolt and nut; This fixed form operation is simple, good fixing effect.
Voltage transformer device body in the utility model, carrying out before insulation pouring, is fixedly connected with location-plate 5 supporter 4 respectively with mould, by the fixing primary winding 1 of supporter 4, by the fixing secondary coil 2 of location-plate 5; This fixed form operation difficulty is little, good fixing effect, and the fixing rear insulating material that directly adopts is poured into a mould, and insulating material can adopt resin.Pouring technology is simple, and after cast, product partial discharge quantity is lower, has reduced product cost.
