Abstract
A kind of electronic current mutual inductor of band support is the utility model is related to, specifically includes air core coil, U-shaped folder, fishbolt and studdle；Air core coil is fixed on to the bottom of four U-shaped folders by fishbolt, tested power line is adjusted through the position of air core coil using studdle dynamic；The utility model is simple in structure, install convenient, avoids due to the problem of electronic current mutual inductor measurement accuracy caused by tested power line punching position and angle difference reduces, the current measurement suitable for the electric system under each voltage class.
Description
Technical field
Present document relates to a kind of electronic current mutual inductor of band support, belong to power electronic equipment field.
Background technology
Current transformer is widely used in the measurement and protection of electric system, is primary equipment important in electric system.
As power system device is towards miniaturization, intelligent, the direction of networking is developed, and electronic current mutual inductor is in every field
In application it is more and more extensive, be free of iron core yet with electronic current mutual inductor so that electronic current mutual inductor is having
Have the advantages that also have output induced potential amplitude minimum while light-weight, insulation is simple and reliable, the characteristics of being easily disturbed.Reason
The electronic current mutual inductor thought will not be influenced be subject to tested conducting wire punching position, punching angle, but in actual production
It is difficult to ensure that the craft precision of electronic current mutual inductor in journey, thereby, it is ensured that to pass perpendicularly through electronic current mutual for tested power line
The center of circle of sensor is the key issue that electric current metering is carried out using electronic current mutual inductor.
Utility model content
For above-mentioned deficiency of the prior art, the utility model proposes a kind of electronic current mutual inductance of band support
Device, by adjusting studdle, realizes the dynamic adjustment of the punching position of tested power line.
In order to achieve the above objectives, the technical solution of the utility model is：
A kind of electronic current mutual inductor of the band support of the utility model, including：Air core coil, U-shaped folder, fishbolt
And studdle；Four U-shaped folders are placed at the position at 90 ° of the air core coil interval, by fishbolt air core coil
It is fixed on the bottom of four U-shaped folders；Screw hole is provided with the U-shaped folder；Described studdle one end is knob, and the other end is
Rubber washer, studdle are screwed into the screw hole in U-shaped folder, and the position of studdle is adjusted by knob.
The framework material of the air core coil is epoxy resin.
The coil of the air core coil is enameled wire, winding mode using it is double-deck it is close around.
The air core coil shell uses ABS plastic housing.
The material of the U-shaped folder, fishbolt and studdle is ABS plastic.
The studdle is marked with the scale of distance between knob center and the air core coil center of circle.
The beneficial effects of the utility model are：The punching position of tested power line is adjusted by four studdle dynamics,
It ensure that the vertical positional relationship of air core coil and tested power line, the mutual inductor adjustment mode is simple, avoids conditional electronic
Formula current transformer is tested the inconvenience of the punching position of power line by ground supports structural adjustment when installing, preferably ensure that
The measurement accuracy of electronic current mutual inductor.
