Abstract
The utility model provides a current mutual inductor which comprises an epoxy resin main body, wherein left and right secondary wiring terminals are arranged on the upper part of the epoxy resin main body; a bump is arranged on one side of each secondary wiring terminal, and through holes are formed on bumps of the corresponding left and right second wiring terminals; and a strip is arranged between left and right secondary wiring terminals, and forms a T shape together with the bumps. According to the current mutual inductor, the strip and the bumps are arranged, thus avoiding short circuit happening to the tail end of a secondary lead connecting wire and improving the electric insulation and the safe performance.
Description
Technical field
The utility model relates to the instrument transformer technology industry, is a kind of current transformer.
Background technology:
Current transformer must satisfy the needs of operation of power networks and metering on electric property, on electrical structure, must satisfy the needs of installing, using.The current transformer of poured with epoxy resin be winding 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 is positioned at body of epoxy resin top, does not take corresponding measure around the secondary connection terminal, when mounted; The secondary connection terminal is with after the secondary lead wires connecting line is connected; In use, the terminal short circuit phenomenon of secondary lead wires connecting line can occur, have potential safety hazard.
The utility model content
The purpose of the utility model is the deficiency that overcomes prior art, and a kind of current transformer is provided, and the connecting line of secondary connection terminal is not easy to occur short circuit phenomenon, and it is safe and reliable.
The technical scheme that technical problem adopted that the utility model solves is: a kind of current transformer; Comprise body of epoxy resin; Two secondary connection terminals 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.During use, connecting line is fixed on connecting line on the secondary connection terminal with securing member through perforation.Side at the secondary connection terminal is provided with projection, has increased secondary connection terminal and the creepage distance that switch cabinet body is installed, and has improved the electrical insulation properties of current transformer.The secondary lead wires connecting line is connected with the secondary connection terminal through the perforation of projection, and the phenomenon of short circuit can appear in the secondary lead wires connecting line end that original technology just can not occur.
During concrete the use, about the secondary connection terminal between be provided with a grade bar, shelves bar and projection formation " T " word shape.The shelves bar can guarantee the insulation distance between the secondary connection terminal of the left and right sides, guarantees that further the end of secondary lead wires connecting line the short circuit phenomenon can not occur.
The beneficial effect of the utility model is: the utility model is provided with grade bar and projection, prevents that the phenomenon of short circuit from can appear in secondary lead wires connecting line end, improved electric insulation and security performance.
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, shelves bar 5, perforation 6, circular hole.
Embodiment:
Like Fig. 1, shown in Figure 2, a kind of current transformer comprises body of epoxy resin 1; The winding of the current transformer of poured with epoxy resin is on ring structure iron core; Winding and ring structure iron core form with poured with epoxy resin, and body of epoxy resin is provided with the circular hole 6 of wearing busbar or wearing cable, two secondary connection terminals 2 about body of epoxy resin 1 top is provided with; One side of secondary connection terminal is provided with projection 3; The projection 3 of the secondary connection terminal about correspondence is provided with perforation 5, about 2 of secondary connection terminals be provided with grade bar 4, shelves bar 4 forms " T " word shapes with projection 3.During use, the secondary lead wires connecting line is fixed on connecting line on the secondary connection terminal 2 with securing member through perforation.Side at secondary connection terminal 2 is provided with projection 3, has increased secondary connection terminal 2 and the creepage distance that switch cabinet body is installed, and has improved the electrical insulation properties of current transformer.Shelves bar 4 can guarantee the insulation distance of 2 of left and right sides secondary connection terminals, and the secondary lead wires connecting line is connected with secondary connection terminal 2 through the perforation 5 of projection 3, and the phenomenon of short circuit can appear in the secondary lead wires connecting line end that original technology just can not occur.
Claims (2)
