Description
Technical field
The utility model belongs to low-voltage electric energy metering field, and especially a kind of small area analysis is than electricity stealing preventive metering Current Transformer.
Background technology
Existing low-temperature measurement small area analysis is than instrument transformer general employing bus type instrument transformer, because bus type instrument transformer does, its small area analysis specific volume of punching one circle is large, error large, Heavy Weight, cost are high, multiplex bus type big current changes its current ratio than instrument transformer by winding cable number of turn and realizes, its shortcoming is as follows: winding cable number of turn can reduce by user, more time-dependent current ratio, increase multiplying factor, thus realize stealing object; Its primary line outlet pillar is porcelain vase formula, centre have conducting rod, accessory many, not easily organize production; Porcelain vase and casing are used rubber gasket between fixing or are sealed with glass cement, easy aging infiltration; The multiplex riveting of label or stickup, easily change label stealing; Therefore should improve prior art.
Utility model content
For the problems referred to above, the utility model aim to provide a kind of accessory few, be easy to that tissue is produced, the low small area analysis of cost is than electricity stealing preventive metering Current Transformer.
For realizing this technical purpose, the utility model provides following technical scheme:
A kind of small area analysis is than electricity stealing preventive metering Current Transformer, comprise multiple circle formula current transformer body, casing, mounting panel, lead seal hole, cover plate and holding screw, described multiple circle formula current transformer body is provided with label and copper Wiring nose, described three multiple circle formula current transformer bodies evenly embed in casing successively, described copper Wiring nose is connected with the end being arranged on the intrinsic cable of multiple circle formula current transformer, described copper Wiring nose is positioned at casing, the framework of described casing side is provided with two lead seal holes, and described box inside is provided with mounting panel.
As further program of the utility model: described label four limit all embeds in multiple circle formula current transformer body.
As further program of the utility model: be provided with cover plate outside described casing, and cover plate is fixed on casing by holding screw.
Compared with prior art, the beneficial effects of the utility model are: reduce by this kind of metering instrument transformer accessory, make it handsome in appearance generous, are easy to produce; A cable resin mixture of instrument transformer and winding is cast for one, change instrument transformer and casing fix between sealing means.Semi-finished product large velocity ratio bus type instrument transformer is made multiple circle formula instrument transformer by winding primary line, obtains little no-load voltage ratio; The primary line of winding and instrument transformer directly pour into a mould one by resin mixture.Instrument transformer label and no-load voltage ratio indication plate adopt embedded structure to be directly cast for one with instrument transformer, make label never drop-off, and instrument transformer outlet employing copper bar formula, contacts effective.Instrument transformer and casing have waterproof silicone rubber O-ring in the middle of fixing.Never leak during fixed installation.Casing is directly installed and is covered in transformer secondary outgoing line side, and is added with lead seal hole, can reach power-steeling preventing effect.
Accompanying drawing explanation
Fig. 1 is internal structure schematic diagram of the present utility model;
Fig. 2 is overall structure schematic diagram of the present utility model;
In figure: 1-multiple circle formula current transformer body, 2-label, 3-copper Wiring nose, 4-casing, 5-mounting panel, 6-lead seal hole, 7-cover plate, 8-holding screw.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1 and Fig. 2, in the utility model embodiment, a kind of small area analysis is than electricity stealing preventive metering Current Transformer, comprise multiple circle formula current transformer body 1, casing 4, mounting panel 5, lead seal hole 6, cover plate 7 and holding screw 8, described multiple circle formula current transformer body 1 is provided with label 2 and copper Wiring nose 3, described three multiple circle formula current transformer bodies 1 evenly embed in casing 4 successively, described label 2 four limit all embeds in multiple circle formula current transformer body 1, described copper Wiring nose 3 is connected with the end of the cable be arranged in multiple circle formula current transformer body 1, described copper Wiring nose 3 is positioned at casing 4, cover plate 7 is provided with outside described casing 4, and cover plate 7 is fixed on casing 4 by holding screw 8, the framework of described casing 4 side is provided with two lead seal holes 6, mounting panel 5 is provided with inside described casing 4.
To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the utility model.Any Reference numeral in claim should be considered as the claim involved by limiting.
In addition, be to be understood that, although this specification is described according to execution mode, but not each execution mode only comprises an independently technical scheme, this narrating mode of specification is only for clarity sake, those skilled in the art should by specification integrally, and the technical scheme in each embodiment also through appropriately combined, can form other execution modes that it will be appreciated by those skilled in the art that.
