Abstract
The invention relates to a method for winding a stepped inductance coil for an inductance sensor. The method relates to the stepped coil, a cylindrical framework and coil sleeves, wherein the coil is supported by the cylindrical framework and the coil sleeves, and the stepped coil is divided into three sections and wound. The coil sleeves are installed on the coil to fix the coil. After the coil is wound according to the designed number of layers through a close winding method, the first coil sleeve is installed at one end of the first coil, then, the second coil is wound, the second coil sleeve is installed, eventually, the third coil is wound through the close winding method, and two layers of alkali-free glass fiber cloth coats the upper portion of the second coil sleeve and upper portion of the third coil sleeve for fixation. By the adoption of the method, wires can be orderly arranged, the original shape can be well maintained, linearity of the inductance sensor is improved, and measurement accuracy is improved.
Description
Technical field
The present invention relates to a kind of telefault method for winding, relate to the inductance sensor field, relate in particular to a kind of stepped appearance telefault winding method that is applied to inductance sensor.
Background technology
Telefault is the vital part in inductance sensor, when the magnetic core of coil inside moves, the inductance of telefault can change, can obtain the displacement of magnetic core by the variation of perception coil inductance, magnetic core is connected with gauge head usually, and then can obtain the displacement of gauge head.Can form a magnetic field after coil electricity, desirable magnetic field is uniform, the variation of the inductance value of coil keeps good linear relationship with the displacement energy of magnetic core like this, but the synergistic effect due to coil magnetic field, cause the middle zone of coil owing to being subject to the right and left magnetic field superposition that coil produces, thereby the magnetic field of coil zone line is stronger, the magnetic field of coil two end regions a little less than.So when magnetic core when section moves in coil the coil inductance value to change not be linearity, and then affect sensor performance, the reduction measuring accuracy.
For addressing the above problem, the present invention proposes a kind of stepped appearance telefault winding method that is applied to inductance sensor, and coiling forms an approximate uniform magnetic field, and the method can make the wire winding displacement neat, can well keep original shape, improve the linear sensor degree and improve measuring accuracy.
Summary of the invention
The object of the present invention is to provide a kind of stepped appearance telefault winding method that is applied to inductance sensor, the method proposes a kind of winding method for the telefault characteristics of inductance sensor, can improve the linear sensor degree, improve measuring accuracy.
For achieving the above object, it is a kind of stepped appearance telefault winding method that is applied to inductance sensor that the present invention adopts technical scheme, and the method comprises several steps: (a) on cylindrical skeleton, use close around the bottom coil of the method coiling design number of plies; (b) in the top of coil I hookup wire snare I and coiling II; (c) top hookup wire snare II and the coil III of online snare I and coil II; (d) top of online snare II and coil III is wrapped up two-layer alkali-free glass fiber cloth it is fixed.
With traditional winding method, compare, the inventive method can make the wire winding displacement neat, can well keep original shape, improves the inductance sensor linearity, improves measuring accuracy.
