Abstract
The existing problems in the field of controlling the insulation thickness of cylindrical frames in the process of automatic winding are shown. Methods of controlling the insulation thickness of steel and plastic frames used in the electrical industry are also analyzed.Control of the insulation thickness after winding increases the amount of waste thermal insulation from expensive materials (for example, glass insulation), eliminating the identified violations is rather time-consuming and can make products unusable. Therefore, automation of the insulation thickness control process during winding has always been a difficult but urgent task. The solution to this problem can eliminate manual labor, reduce waste and improve the quality of industrial products used in the electrical and radio engineering industries. Operation principles, physical models and applications of various types of electromagnetic transducers of non-electrical quantities to electrical ones are considered. Features and characteristics of the main types of electromagnetic transducers of the insulation thickness of frames are analyzed. The characteristics of the main types of electromagnetic transducers of the thickness of glass insulation of frames are compared, their relative advantages and disadvantages are shown. Based on the analysis of the appropriate methods for controlling the thickness of various elements, problems are identified in the automation of insulation thickness control of plastic and steel frames in the winding process. Comparative analysis of the designs and characteristics of existing transducers shows that it is necessary to improve the design of linear induction levitation-screen suspensions and create effective methods of transmitting displacements to the levitation screen. Then the obtained unconventional designs can be successfully used for automatic control of the insulation thickness during winding it on rotating frames. For this purpose, differential inductive and transformer transducers with levitation screens and moving measuring windings are recommended. These transducers provide the required measurement accuracy, unambiguous continuous conversion of the insulation thickness into an electric signal in the winding process.
Highlights
In the radio engineering and electrical industries, fiberglass and steel elements of a cylindrical profile with external insulation are widely used
Detection and elimination of deviations of the linear dimensions of the frames from those established after the completion of the process lead to additional material costs
To ensure accurate control of the insulation thickness in the winding process, transducers are subject to the following requirements: linearity of the static characteristic, high sensitivity, minimum influence of auxiliary elements on transducer characteristics and the least residual signal at the output
Summary
In the radio engineering and electrical industries, fiberglass and steel elements of a cylindrical profile with external insulation are widely used. Controlling the thickness of insulation winding on rotating frames is a more difficult task than controlling the linear dimensions of non-moving parts. Mass production of such frames requires automation of control of linear dimensions (frame diameter) in the winding process. Measurement of the insulation of frames after winding by non-electric methods is inaccurate and leads to a decrease in the quality of industrial products based on fiberglass elements. When using non-electric methods in the winding process, relative inaccuracy is preserved, adjustment and matching of the transducer design with the object are complicated. One of the solutions to the problems is the development of contactless electromagnetic and electromechanical automation devices, among which primary electromagnetic displacement transducers of inductive and transformer types are of great importance. It becomes necessary to determine the optimal method and design to solve this problem
