Abstract

The utility model relates to current transformer technical field, especially a kind of novel two-sided magnetic screen instrument transformer, comprise shell, iron core, enamelled wire and lead-in wire, the iron core being wound with enamelled wire is installed in shell, lead-in wire stretches out in shell, in described shell, upper and lower end face is respectively provided with one deck shielding sheet, and described shielding sheet side is provided with half round dot groove, and it is protruding that side is provided with half round dot.Described shielding sheet is 50W800 silicon steel material.Described shielding sheet is pasted the upper and lower end face sidewall of shell one week by adhesive.The utility model not only ensure that the performance of original instrument transformer, also improves the ability of instrument transformer phasetophase current balance type, ensure that instrument transformer circuit breaker under overload current misoperation does not occur, and reduces the loss formed because of product misoperation.

Description

Novel two-sided magnetic screen instrument transformer
Technical field
The utility model relates to current transformer technical field, especially a kind of novel two-sided magnetic screen instrument transformer.
Background technology
Original instrument transformer side is provided with shielding sheet, but in practice, due to asymmetric between phase place, will affect breaker actuation, and when adding multi-disc, conventional glue is bonding, so that need clean glue when utilizing next time, cumbersome.
Utility model content
In order to overcome the deficiencies in the prior art, the utility model provides a kind of novel two-sided magnetic screen instrument transformer that can solve the circuit breaker misoperation caused because of unbalance in phase, and easy accessibility between multilayer screen sheet, be convenient to recycling.
The utility model solves the technical scheme that its technical problem adopts: a kind of novel two-sided magnetic screen instrument transformer, comprise shell, iron core, enamelled wire and lead-in wire, the iron core being wound with enamelled wire is installed in shell, lead-in wire stretches out in shell, in described shell, upper and lower end face is respectively provided with one deck shielding sheet, described shielding sheet side is provided with half round dot groove, and it is protruding that side is provided with half round dot.
According to another embodiment of the present utility model, comprising described shielding sheet is further 50W800 silicon steel material.
According to another embodiment of the present utility model, comprise described shielding sheet outermost synusia further and pasted the upper and lower end face sidewall of shell one week by adhesive.
According to another embodiment of the present utility model, comprise described adhesive further and mixed by epoxy resin and curing agent.
The beneficial effects of the utility model are, the utility model not only ensure that the performance of original instrument transformer, also improve the ability of instrument transformer phasetophase current balance type, ensure that instrument transformer circuit breaker under overload current misoperation does not occur, reduce the loss formed because of product misoperation.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is A-A segment structure cutaway view in Fig. 1.
In figure 1, shell, 11, shielding sheet, 2, iron core, 3, enamelled wire, 4, lead-in wire.
Embodiment
If Fig. 1 is structural representation of the present utility model, a kind of novel two-sided magnetic screen instrument transformer, comprise shell 1, iron core 2, enamelled wire 3 and lead-in wire 4, the iron core 2 being wound with enamelled wire 3 is installed in shell 1, lead-in wire 4 stretches out in shell 1, in described shell 1, upper and lower end face is respectively provided with one deck shielding sheet 11, described shielding sheet (11) side is provided with half round dot groove, it is protruding that side is provided with half round dot, half round dot groove and half round dot projection are superimposed, two pieces of shielding sheets can fit tightly and not easily loosen, and when not needed, can conveniently pull down.Shielding sheet 11 of the present utility model is 50W800 silicon steel material.
During enforcement, shielding sheet 11 outermost synusia is pasted the upper and lower end face sidewall of shell 1 one week by adhesive, and all the other shield sheets and are superimposed and are placed on both sides.Adhesive is mixed by epoxy resin and curing agent.Because original instrument transformer can not meet asymmetric between phase place and breaker actuation, instrument transformer of the present utility model can realize this function when not increasing cost.
The utility model not only ensure that the performance of original instrument transformer, also the ability of instrument transformer phasetophase current balance type is improved, improve the recycling property of shielding sheet, ensure that instrument transformer circuit breaker under overload current misoperation does not occur, reduce the loss formed because of product misoperation.
