Background technology
At present, current transformer is commonly used in power network line and switch cubicle, the equipment as current measurement and protection.It is existing
The structure design of some current transformers is unreasonable, and for the current transformer in cast, the coil inside current transformer can not
It is fixed, cause to pour into a mould inconvenient, so as to which the current transformer has the defects of production efficiency is relatively low, and the current transformer is interior
Portion's coil layout is unreasonable, so as to which the current transformer has the defects of cost is high, performance is unstable.
The content of the invention
The defects of the purpose of this utility model is to overcome prior art, there is provided it is a kind of it is compact-sized, stable and reliable for performance,
The low current transformer of cost.
To achieve the above object, the utility model uses a kind of current transformer, including primary winding, multiple secondary lines
Circle, two leads, epoxy resin poured body, the P1 copper busbars being arranged in epoxy resin poured body and P2 wiring copper
Row, described primary winding is in box shape, and described multiple secondary coils are divided into two groups of secondary windings, described two groups of windings pair
Title is arranged on the both sides of primary winding, and fixation kit, described fixation kit bag are provided with described two groups of secondary windings
Include the upper mounted plate for the lower surface for being arranged on two groups of secondary windings, the lower fixation being arranged on the upper surface of two groups of secondary windings
Plate, the screw rod being connected between upper mounted plate and bottom plate, the exit of described two leads sequentially pass through respectively
The upper through hole of upper mounted plate, the center hole of two groups of secondary windings, bottom plate lower through-hole and be connected to P1 copper busbars,
On P2 copper busbars, described primary winding, multiple secondary coils, fixation kit are integrally made up of institute poured with epoxy resin
The epoxy resin poured body stated.
The beneficial effect of said structure is：Fixation kit is provided with the secondary coil of the current transformer, in cast,
Primary winding, secondary coil disposably can load in casting mold, substantially increase production efficiency, while also ensure that once
Insulation distance between coil and secondary coil, improve the reliability of the operation of current transformers, and two leads point
Not Chuan Guo two secondary windings, be advantageous to shorten two leads extraction length, so as to save cost and energy consumption, so as to
The current transformer has the advantages of compact-sized, stable and reliable for performance, cost is low.
Especially, the shape of described upper mounted plate, bottom plate is in long circular, described upper through hole, lower through-hole
It is Long Circle, multiple copper inserts is provided with the lower surface of described upper mounted plate.Copper insert on upper mounted plate can be fixed
On the bottom plate of casting mold, secondary coil will not offset out installation site, ensure that the insulation of primary winding and secondary coil
Distance.

111, described two groups of windings 111 are symmetricly set on the both sides of primary winding 10, are set in described two groups of secondary windings 111
There is fixation kit, described fixation kit includes being arranged on the upper mounted plate 21 of the lower surface of two groups of secondary windings 111, is arranged on
Bottom plate 22 on the upper surface of two groups of secondary windings 111, the screw rod being connected between upper mounted plate 21 and bottom plate 22
23, described upper mounted plate 21, the shape of bottom plate 22 are equal in long circular, described upper through hole 211, lower through-hole 221
For Long Circle, multiple copper inserts 212 are provided with the lower surface of described upper mounted plate 21.Copper insert on upper mounted plate can be consolidated
It is scheduled on the bottom plate of casting mold, secondary coil will not offset out installation site, ensure that the exhausted of primary winding and secondary coil
Edge distance.211, two groups of the upper through hole that the exit of two described leads 12 sequentially passes through upper mounted plate 21 respectively is secondary
The center hole 112 of winding 111, the lower through-hole 221 of bottom plate 22 and it is connected to P1 copper busbars 14, P2 copper busbars 15
On, described primary winding 10, multiple secondary coils 11, fixation kit are integrally made up of described ring poured with epoxy resin
Oxygen resin-cast body 13.
Fixation kit is provided with the secondary coil of the current transformer, in cast, primary winding, secondary coil can one
In the loading casting mold of secondary property, production efficiency is substantially increased, while also ensure that between primary winding and secondary coil
Insulation distance, the reliability of the operation of current transformers is improved, and two leads are each passed through two secondary windings, have
Beneficial to the extraction length for shortening two leads, so as to save cost and energy consumption, so as to which the current transformer has structure
The advantages of compact, stable and reliable for performance, cost is low.
