漆包线的测量（Measurement of enameled wire） Measurement of the size of enameled wire! ~! ~! Chapter 1 measurement of enameled wire The enameled wire is a wire that is insulated with paint film, mainly used for electrical, electrical and electrical instrument winding, to realize electromagnetic energy conversion. With the development of electrical industrial products, for its form a complete set of enameled wire has small volume, large capacity, high temperature resistant, resistant to high pressure, high mechanical strength, good electric performance and meet the need of special environmental conditions. In order to meet these requirements, the variety of enameled wire is more and more, the quality requirement is higher and higher. Because of this, the inspection project and detection means of enameled wire should be more and more strict. The technical quality of the inspection personnel of the lacquers is becoming higher and higher. Section 1 purpose and measuring tools for measurement of dimensions Measurement item The dimensions of the enameled circular line include five indicators, such as the diameter of the conductor, the allowable deviation of the diameter of the conductor, the thickness of the section, the thickness of the minimum paint film and the maximum outer diameter. The allowable deviation of the diameter of the conductor is the allowable deviation between the actual value of the diameter of the naked conductor and the regulation value. The minimum thickness of the paint film is the difference between the maximum diameter and the measured diameter of the conductor. (the measured diameter includes the diameter of the copper wire and the permissible deviation. The uncircularity of the wire is the maximum value of the difference between the maximum measured value and the minimum measured value of the same section diameter of each conductor. The maximum outer diameter of the enameled wire is the maximum allowable value of the index diameter, allowable positive d
