Description
Technical field
A kind of current transformer is the utility model is related to, particularly a kind of current transformer of diamagnetic field force interference.
Background technology
In the prior art, the manufacture craft of current transformer mainly has two kinds：First, after coil being pricked into upper wire, even
The place of connecing puts small casing (preventing short circuit), then winds coil with insulating tape and wraps up, then puts heat-shrinkable T bush insulation, then will
U-shaped copper bar passes through coil, is finally fixed coil and U-shaped copper bar with gluing process；2nd, coil is pricked after upper wire and be put into
In the plastic casing of PBT material, then filled with epoxy resin material, cover with ferrous material, then again put plastic casing
Enter in U-shaped ferrous material housing, then sealed iron covering with epoxy resin material.
But the current transformer that prior art first way is prepared by the manufacture craft, diamagnetic field energy power are paid no attention to
Think, such as to reach it is high it is diamagnetic be put into requirements, magnetic core dosage, cost height need to be increased；Meanwhile insulation mainly passes through adhesive tape and thermal shrinkable sleeve
Pipe realizes that insulation effect is bad, and the mechanical strength of current transformer is low.The prior art second way is by using ferrous material
The mode of sealing improves diamagnetic effect, but complex process, cost are higher.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of strong diamagnetic of cost-effective, diamagnetic field interference performance
The current transformer of field force interference.
In order to solve the above technical problems, the utility model provides a kind of current transformer of diamagnetic field force interference, including
Shell, coil and upper lid, shell are provided with mounting groove, and coil is placed in the mounting groove of shell, and the binding post stretching of coil is outer
On the outside of shell, upper lid is covered at shell aperture, is filled between upper lid and shell mounting groove with epoxy resin material；
Shell includes the shell core of housing and tubulose, and housing upper surface is provided with mounting groove, and housing lower surface is provided with and mounting groove
The through hole communicated, shell core coordinate with housing, and shell core bottom outer wall is provided with projection, and shell core lower end is stretched into through hole, the projection of shell core
It is resisted against on the lower surface of housing mounting groove, in the middle part of shell core and top is all in mounting groove, and mounting coil is on the outside of shell core, line
The lower surface of circle is contacted with the raised upper surface of shell core, and the upper end of shell core is resisted against on lid.
Technology contents of the present utility model are understood in order to clearer, below by the current transformer of this diamagnetic field force interference
Referred to as this current transformer.
The material of this current transformer housing is ferrous material；The material of the shell core is plastic material.
After such structure, coil is put into housing and filled with epoxy, then is sealed with ferrous material, and the purpose is to generation
For to the mode that insulating tape is wound in existing technique (efficiency far of epoxy material filling is higher than winding insulating tape), ensure coil
Pressure-resistant insulation.
Shell includes housing and shell core, two parts assemble be exactly an entirety shell, instead of original two shells
The trouble of son.
Coil is put into shell, and the material of shell core is insulation, but housing is ferrous material, and on-insulated, if will
Coil directly contacts with housing will be short-circuit, so in shell as design, shell core is provided with projection, and such coil is put into outer
There is a safe distance after shell, between coil and housing, the inside is filled with epoxy material again, can reach the effect of insulation.
Advantageous effects of the present utility model are：Auxiliary material is reduced, reduces cost, the step of reducing technological process, is carried
High manufacture and processing efficiency.
Brief description of the drawings
Fig. 1 is the sectional view of this current transformer embodiment.
Fig. 2 is Fig. 1 along A-A to sectional view.
Embodiment
As shown in Fig. 1 to 2 (technical pattern of the application is observed for convenience, epoxy resin is omitted in Fig. 2)
This current transformer includes shell, coil 2 and upper lid 3.
