Abstract
A current transformer capable of preventing electricity stealing comprises an epoxy resin main body, wherein secondary wiring terminals arranged in left-and-right mode are arranged on the upper portion of the epoxy resin main body, convex blocks are arranged on one sides of the secondary wiring terminals, correspondingly penetrating holes are arranged on the convex blocks of the secondary wiring terminals arranged in left-and-right mode, and cover bodies are fixedly arranged on the secondary wiring terminals. The cover bodies are adopted to seal the secondary wiring terminals in covering mode so that short circuits and loosening electricity stealing at positions of the secondary wiring terminals of the original transformer are avoided, and the current transformer capable of preventing electricity stealing is improved in insulation performance and safe and reliable to use.
Description
Technical field
The utility model relates to the instrument transformer technology industry, is a kind of anti-electricity-theft current transformer.
Background technology:
Present indoor metering is adopted casting insulated architecture with dry-type current transformer; Winding is on ring structure iron core; Form with poured with epoxy resin, body of epoxy resin is provided with the circular hole of wearing busbar or wearing cable, the secondary connection terminal with poured with epoxy resin on main body top.At present, the secondary connection terminal exposes, easily by lawless person's stealing.
The utility model content
The purpose of the utility model is the deficiency that overcomes prior art, and provide a kind of simple in structure, reasonable in design, easy for installation, dielectric strength is high, the dry-type current transformer of thief-proof good electrical property.
The technical scheme that technical problem adopted that the utility model solves is: a kind of anti-electricity-theft current transformer; Comprise body of epoxy resin; The secondary connection terminal of arranging about body of epoxy resin top is provided with; It is characterized in that being provided with projection in a side of secondary connection terminal, the projection of the secondary connection terminal about correspondence is provided with perforation, is fixed with cover body on the secondary connection terminal.The secondary lead wires connecting line is connected with the secondary connection terminal through the perforation of projection, is fixed with cover body on the secondary connection terminal, so just avoids adopting originally instrument transformer secondary connection terminal place short circuit and the loosening electricity of stealing, and insulation property are improved, and are safe and reliable.
During concrete the use, about the secondary connection terminal between be provided with a grade bar, a shelves bar is provided with screw, uses with the suitable screw of screw to be fixed on cover body on grade bar.
During concrete the use, on cover body, be provided with projection with holes, the head of screw is provided with the hole.The method of lead sealing can be used in the hole of projection and screw head, guarantees its anti-theft feature.
During concrete the use, cover body is a transparent cover.
The beneficial effect of the utility model is: the utility model is because the secondary connection terminal that adopted the cover body capping so just avoids adopting originally instrument transformer secondary connection terminal place short circuit and the loosening electricity of stealing, and insulation property are improved, and are safe and reliable.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified:
Fig. 1 is that the master of the utility model embodiment looks sketch map.
Fig. 2 is the schematic top plan view of the utility model embodiment.
Among the figure 1, main body 2, secondary connection terminal 3, projection 4, perforation 5, cover body 6, shelves bar 7, screw 8, projection.
Embodiment:
Like Fig. 1, shown in Figure 2; A kind of anti-electricity-theft current transformer comprises body of epoxy resin 1, winding and ring structure iron core, and winding and ring structure iron core form with poured with epoxy resin; Body of epoxy resin is provided with the circular hole of wearing busbar or wearing cable; The secondary connection terminal of arranging about body of epoxy resin 1 top is provided with 2 is provided with projection 3 in a side of secondary connection terminal 2, and the projection 3 of the secondary connection terminal 2 about corresponding is provided with perforation 4; Be fixed with cover body 5 on the secondary connection terminal 2, cover body 5 is a transparent cover.About 2 of secondary connection terminals be provided with grade bar 6, shelves a bar 6 be provided with screw, use with the suitable screw 7 of screw to be fixed on cover body on grade bar 6; On cover body 5, be provided with projection with holes 8, the head of screw 6 is provided with the hole.The secondary lead wires connecting line is connected with secondary connection terminal 2 through the perforation of projection 3; Be fixed with cover body 5 on the secondary connection terminal 2; So just avoid adopting originally instrument transformer secondary connection terminal 2 place's short circuits and the loosening electricity of stealing, insulation property are improved, and are safe and reliable.The method of lead sealing can be used in the hole of projection 8 and screw 7 heads, guarantees its anti-theft feature.
