Description
Technical field
The utility model relates to instrument transformer, particularly relates to a kind of current transformer.
Background technology
Current transformer principle is according to electromagnetic induction principle, and current transformer is made up of the iron core closed and winding.Its armature winding number of turn is little, and go here and there in the circuit needing the electric current measured, therefore it often has whole electric currents of circuit to flow through, and secondary winding turns is many, is serially connected in measuring instrument and protective loop.In whole current transformer, there is more difficult replacing individual parts, as magnetic core or coiling; At the welded current transformer connected, if welding pin is damaged, be then unfavorable for changing.
Utility model content
The utility model provides a kind of current transformer, for the parts changing instrument transformer are provided convenience, thus cost-saving.
In order to solve the problems of the technologies described above, technical solution adopted in the utility model is:
A kind of current transformer, comprise skeleton, coil and magnetic core, described coil, around on described skeleton, described skeleton is provided with draw-in groove, described magnetic core is socketed with the insulation plastic cement of described pocket matches protruding; Described skeleton both sides are provided with Connection Block, and described Connection Block side is connected with pin, and opposite side is provided with hole clipping, and described pin is electrically connected described hole clipping, and described coil is electrically connected described hole clipping.
Preferably, described coil comprises armature winding and secondary winding, and the number of turn of described armature winding is 5-100 circle, and the number of turn of described secondary winding is 100-10000 circle.
Preferably, the number of turn of described armature winding is 50 circles, and the number of turn of described secondary winding is 5000 circles.
Preferably, described magnetic core is E-type magnetic core.
Alternatively, described magnetic core is U-shaped magnetic core.
Preferably, the material of described magnetic core is Fe-based amorphous alloy.
Preferably, described skeleton is " day " font skeleton.
The utility model provides a kind of current transformer, and this current transformer is provided with the fixing structure being convenient to magnetic core, is provided with middle Connection Block simultaneously, conveniently can realize the inner components changing instrument transformer.
Accompanying drawing explanation
Fig. 1 is a kind of current transformer structure schematic diagram of the utility model.
Embodiment
Below in conjunction with accompanying drawing, specifically illustrate execution mode of the present utility model, accompanying drawing is only for reference and use is described, does not form the restriction to the utility model scope of patent protection.
As shown in Figure 1, a kind of current transformer, comprises skeleton 1, coil and magnetic core, and described coil, around on described skeleton 1, described skeleton 1 is provided with draw-in groove, described magnetic core is socketed with the insulation plastic cement of described pocket matches protruding; Described skeleton 1 both sides are provided with Connection Block 2, and described Connection Block 2 side is connected with pin 3, and opposite side is provided with hole clipping 4, and described pin 3 is electrically connected described hole clipping 4, and described coil is electrically connected described hole clipping 4.Described coil comprises armature winding and secondary winding, and the number of turn of described armature winding is 5-100 circle, and the number of turn of described secondary winding is 100-10000 circle.The number of turn of described armature winding is 50 circles, and the number of turn of described secondary winding is 5000 circles.Described magnetic core is E-type magnetic core.Described magnetic core is U-shaped magnetic core.The material of described magnetic core is Fe-based amorphous alloy.Described skeleton 1 is " day " font skeleton.
Above disclosedly be only preferred embodiment of the present utility model, rights protection scope of the present utility model can not be limited with this, therefore according to the equivalent variations that the utility model claim is done, still belong to the scope that the utility model is contained.
