Abstract
The utility model discloses a current inducer can solve copper conductor because skin effect and the temperature rise problem that exists. Including primary coil and two wiring boards, tubulose that primary coil went up the suit by cylindrical conducting rod and its is led magnetron and is made up and form, the wiring board is " L " shape, comprises the peaceful wiring board of linking arm, is equipped with the connecting hole on this linking arm, primary coil through this connecting hole with the wiring board is connected.
Description
Technical field
The utility model is related to transformer, more particularly to great current mutual inductor.
Background technology
A copper conductor in great current mutual inductor in transformer industry is imitated by that can produce the collection skin of electric current after electric current
Should, charge concentration constantly rises on the surface of Primary Conductor, the over time temperature of conductive surface, and ascending temperature is too high
Insulation ag(e)ing can be made to shorten service life of equipment, even result in insulation breakdown, not reach the temperature increase requirement of national Specification.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of current transformer, can solve the problem that a copper conductor by
In the problem of temperature rise that kelvin effect is present.
In order to solve the above technical problems, the technical solution of the utility model is：Including primary winding and two primary connections
Plate, the primary winding is combined by cylindrical conductive bar and the tubular conductive pipe being set with thereon, and the terminal plate is L-shaped
Shape, is made up of linking arm peace terminal plate, and the linking arm upper end is provided with connecting hole, and the primary winding passes through the connecting hole and institute
State terminal plate connection.
The contact tube two ends are provided with step and are used to be installed in the connecting hole.
The beneficial effects of the utility model are that a copper conductor is by cylindrical conductive bar and the tubular conductive pipe being set with thereon
Composition, this split-type structural generates the effect of shunting, for overcoming the influence produced by kelvin effect, makes a copper conductor
Increased by the net sectional area of electric current, effective resistance diminishes, so as to solve problem of temperature rise.Switch cubicle can also be solved simultaneously
Installation question, reduces volume, reduces cost.

Specific embodiment
As shown in Figure 1, Figure 2, Figure 3 shows, primary winding 3 is split-type structural, by cylindrical conductive bar 1 and tubular conductive pipe 2
Be welded with silver soldering after suit, this split-type structural causes have electric current to flow through on conducting rod 1 and contact tube 2, can with gram
Take the influence produced by kelvin effect；As shown in Figure 4, Figure 5, primary connection plate 4 is in the form of an " L ", by the peaceful terminal plate of linking arm 5
6 compositions, flat terminal plate 6 is threaded hole 8, and the upper end of linking arm 5 is provided with connecting hole 7, and the two ends of contact tube 2 are provided with step 9 and are arranged on
Welded in connecting hole 8 and with silver soldering so that primary winding 3 links together with terminal plate 4.
