Description
[technical field]
The utility model relates to send field of power transformation more particularly to a kind of current transformer core.
[background technique]
Want cube smaller and smaller current transformer currently on the market, detection electric current is increasing, and precision is also increasingly
Height, and traditional mutual inductor is ultramicro-crystal alloy and silicon steel sheet, ultramicro-crystal alloy can satisfy requirement in precision, but right
Volume can increase with it much when detecting high current signal, can not meet the requirement of miniaturization.And silicon steel sheet can with it is super
Detect high several times of high current in the case where microcrystallizing alloy equal volume, the shortcomings that silicon steel sheet is can not in low current signal
Meet high-precision requirement.
Therefore it provides the problem of a kind of improved current transformer core is this field urgent need to resolve.
[utility model content]
The utility model is in view of the above-mentioned problems, provide a kind of high-acruracy survey, current transformer core small in size.
To solve the above-mentioned problems, the utility model provides a kind of current transformer core, the current transformer core
Annularly, the current transformer core include cyclic annular box body, the ultramicro-crystal alloy being installed in the box body, be installed on it is described
Silicon steel sheet below cyclic annular box body, the box body have opening, and the current transformer core, which also has, is installed on the box body
The cover board of opening, the ultramicro-crystal alloy are fixed in the box body by cohesive material, the silicon steel sheet and the box
Body is fixed together by cohesive material.
Further, the box body is that stainless steel protects box.
Further, the cover board is epoxy plate.
Furthermore the current transformer core in the utility model can meet the requirement of high-acruracy survey and protection simultaneously,
The volume of mutual inductor can be effectively reduced.
[Detailed description of the invention]
Fig. 1 is the current transformer iron core structure schematic diagram of the utility model.
[specific embodiment]
It is shown in Figure 1, give the structural schematic diagram of current transformer core in the utility model.
In a ring, the stainless steel including ultramicro-crystal alloy 1, the receiving ultramicro-crystal alloy 1 protects box to current transformer core
2, the epoxy plate 4 that covers on stainless steel shield box 2, the silicon steel sheet 5 for being fixedly connected on stainless steel shield box 2, the ultra micro
Peritectic alloy 1 protects box 2 with the installation of glue 3 to the stainless steel by the way that alloy is fixed, and the silicon steel sheet 5 passes through whole fixed solid with glue 6
It is scheduled on the lower section of the stainless steel shield box 2.The stainless steel shield box 2 is open annular, and the epoxy plate 4 is covered in the stainless steel
It protects on box 2.Current transformer core in the utility model can meet the requirement of high-acruracy survey and protection, Neng Gouyou simultaneously
The volume of the reduction mutual inductor of effect.
In addition, it should be understood that although this specification is described in terms of embodiments, but not each embodiment is only wrapped
Containing an independent technical solution, this description of the specification is merely for the sake of clarity, and those skilled in the art should
It considers the specification as a whole, the technical solutions in the various embodiments may also be suitably combined, forms those skilled in the art
The other embodiments being understood that.
