Abstract
A kind of automatic laminating type current transformer, the current transformer is rectangular-ambulatory-plane current transformer, including two coils, coil rack and the tinertoy steel disc passed through from coil, two coils are connected by shorting stub is first, it is connected again by terminal line tail tail, two coils are together in series and form a coil, the tinertoy steel disc is formed by tinertoy after two pieces of axially symmetric steel disc connections, described two pieces axially symmetric steel discs pass through coil rack clamping, form field circuit, described two pieces axially symmetric steel disc junctions are the groove and protrusion mutually agreed with, one length of side of groove is short on one side, the protrusion can just be embedded in the groove.The problem of the utility model carries out intersection lacing film to solve traditional silicon steel sheet using UI shaped steel piece, is then fixed with rivet, and efficiency is low provides a kind of quick automatic laminating type current transformer easy for installation.
Description
Technical field
The utility model belongs to current transformer, and in particular to tinertoy type current transformer field.
Background technology
Current transformer is made of the iron core and winding being closed.Its first side winding number of turn is few, and going here and there is needing to measure
Electric current circuit in, secondary side winding turn ratio is more, is serially connected in measuring instrumentss and protective loop.It is closed using rectangular-ambulatory-plane
In the current transformer for closing iron core, traditional silicon steel sheet carries out intersection lacing film using UI shaped steel piece, is then fixed with rivet, efficiency is non-
It is often low, using a large amount of artificial.There are no a kind of effective and convenient current transformer core installation methods currently on the market.
Invention content
The utility model to solve the above-mentioned problems, provides a kind of automatic laminating type current transformer easy for installation.
A kind of automatic laminating type current transformer, the current transformer is rectangular-ambulatory-plane current transformer, including two lines
Circle, coil rack and the tinertoy steel disc passed through from coil, two coils are connected, then pass through terminal line tail tail by shorting stub is first
It is connected, two coils is together in series and form a coil, the tinertoy steel disc is folded after being connected by two pieces of axially symmetric steel discs
Riveting forms, and described two pieces axially symmetric steel discs pass through coil rack clamping, form field circuit, two blocks of axially symmetric steel
Piece junction is the groove and protrusion mutually agreed with, and one length of side of groove is short on one side, and the protrusion can just be embedded in described
Groove.
Be equipped with bump structure on the inside of the long side of the groove, another piece of axis relative into tinertoy steel disc relative position be equipped with it is recessed
Into structure, when described two pieces axially symmetric steel discs fasten, the bump structure is embedded in the recessed structures.
Compared with prior art, the utility model has the advantages that：
Utility model is molded using silicon steel sheet automatic laminating, and symmetrical two tinertoy steel discs are compressed, pass through two pieces of steel discs
Groove decoupling fix, easy to operate, efficiency is 10 times of original technique or more.
Description of the drawings
Fig. 1 is the connection figure of 4 automatic laminating type current transformers；
Fig. 2 is the sectional view of automatic laminating type current transformer；
Fig. 3 is the junction enlarged drawing of two pieces of steel discs of automatic laminating type current transformer.
Specific embodiment
The structure of the utility model and the course of work are described further below in conjunction with the accompanying drawings.
As shown in Figure 1：A kind of automatic laminating type current transformer, current transformer are rectangular-ambulatory-plane current transformer, including
Two coils 1, coil rack and the tinertoy steel disc 2 passed through from coil, two coils are connected, then pass through by shorting stub 3 is first
4 tail tail of terminal line is connected, and two coils are together in series and form a coil, and tinertoy steel disc is connected by two pieces of axially symmetric steel discs
It connects rear tinertoy to form, two pieces of axially symmetric steel discs pass through coil rack clamping, form field circuit.
As shown in Figure 2,3：Two pieces of axially symmetric steel disc junctions are the groove 5 and protrusion 6 mutually agreed with, and groove is on one side
Long short on one side, protrusion can just be embedded in groove.Be equipped with bump structure 8 on the inside of the long side of groove, another piece of axis relative into it is folded
Riveting steel disc relative position is equipped with recessed structures 9, when two pieces of axially symmetric steel discs fasten, in bump structure insertion recessed structures.
In use, 4 identical mutual inductors are inserted into same shell son terminal 10 by terminal line forms complete set
Current transformer.
Embodiment described above only expresses a kind of embodiment of the utility model, and description is more specific and detailed,
But it should not be interpreted as limiting the scope of the present invention.It should be pointed out that for the common of this field
For technical staff, without departing from the concept of the premise utility, various modifications and improvements can be made, these all belong to
In the scope of protection of the utility model.
