Abstract
The utility model discloses a current transformer which comprises a framework and a coil wound on the framework, wherein welding pins are arranged on the framework; the framework is in a shape of a Chinese character 'RI' and is 2 to 5-millimeter high; E-shaped magnetic cores which are 1 to 3-millimeter high are inserted into two sides of the framework and are fixed on the framework by magnetic core steel clamps; the coil is wound on one side of the framework; and a copper sheet is arranged on the other side of the framework. The current transformer has the advantages of flattening, modularization and reliable performance.
Description
Technical field
The utility model relates to instrument transformer, specifically is meant a kind of current transformer.
Background technology
Current transformer is according to electromagnetic induction principle.Current transformer is made up of the iron core and the winding of closure.Its umber of turn seldom, string is in the circuit of the electric current that needs are measured, so it often has whole electric currents of circuit to flow through, the secondary winding turn ratio is more, is serially connected in measuring instrument and the protection loop.
The effect of current transformer is to convert the bigger primary current of numerical value into numerical value less secondary current through certain no-load voltage ratio, is used for protecting, purposes such as measurement.
Along with the develop rapidly of digital electronic goods, to current transformer require increasingly high, pursue its electric property require higher in, volume requirement is more and smaller and more exquisite.
The utility model content
The purpose of the utility model provides the current transformer of a kind of flattening, modularization, dependable performance.
To achieve these goals, the utility model is designed a kind of current transformer, and it comprises skeleton and the coil on the skeleton; Leg is installed on the skeleton, and described skeleton is " day " font skeleton, and the height of skeleton is 2～5mm; Being inserted with in the both sides of skeleton highly is the E type magnetic core of 1～3mm; Magnetic core steel folder is fixed on E type magnetic core on the skeleton, is wound with coil in a side of skeleton, and opposite side is equipped with copper sheet.
The employing groove-splitting design of the utility model current transformer; Coil on the current transformer and copper sheet are horizontally set on the skeleton; Thereby current transformer is made flattening, modularization, and its overall height can be accomplished below the 4mm, its elementary electric current input that can realize 40 amperes.
Description of drawings
Fig. 1 is the plan structure sketch map of the utility model current transformer;
Fig. 2 is the side-looking structural representation of the utility model current transformer.
Embodiment
For the ease of those skilled in the art's understanding, will combine specific embodiment and accompanying drawing that the structural principle of the utility model is done further to describe in detail below.
Like Fig. 1, shown in Figure 2, a kind of current transformer, it comprises skeleton 1 and the coil 2 on the skeleton 1; Leg 6 is installed on the skeleton 1, and described skeleton 1 is " day " font skeleton, and the height of skeleton 1 is 2～5mm; Being inserted with in the both sides of skeleton 1 highly is the E type magnetic core 3 of 1～3mm; Magnetic core steel folder 4 is fixed on E type magnetic core on the skeleton 1, is wound with coil 2 in a side of skeleton 1, and opposite side is equipped with copper sheet 5.Point has G500 glue 7 between skeleton 1 and E type magnetic core 3, on the magnetic core on first leg, is equipped with white point 8 and makes marks.
Foregoing is merely the preferred embodiment of the utility model, is not the embodiment that is used to limit the utility model, and those skilled in the art are according to the design of the utility model, and appropriate adaptation of having done or modification all should be within the protection ranges of the utility model.
