Rapid eccentricity detection device for enameled wire

Abstract

The invention discloses a rapid eccentricity detection device for an enameled wire. The enameled wire is arranged along a straight line. The detection device comprises a plurality of capacitor plates, a voltage recorder and a power supply, the capacitor plates are respectively arranged along the periphery of the enameled wire, the distances from the inner walls of the capacitor plates to the peripheral wall of the enameled wire are equal, and the capacitor plates, copper conductors in the enameled wire and the voltage recorder are respectively connected with the power supply. And the voltage recorder records the breakdown voltages of the plurality of capacitor plates, and judges the eccentricity degree of the paint film of the enameled wire through the range of the plurality of breakdown voltages. According to the method, the range and the variance of the breakdown voltage can be calculated, so that the effect of quickly judging the eccentricity degree of the paint film is achieved.

Description

technical field [0001] The invention relates to the technical field of enameled wire production and detection, in particular to a rapid eccentricity detection device for enameled wire. Background technique [0002] Larger specifications of enameled wire require thicker paint film thickness. In the production process, the enameled core produced is often seriously eccentric due to the problem that the surface tension of the paint cannot overcome the gravity of the paint and the eccentricity between the filament and the mold. The occurrence of eccentricity seriously affects the electrical properties of the enameled wire, resulting in unqualified enameled wire. In order to avoid substandard products, it is necessary to carry out eccentricity detection on the finished enameled wire. [0003] The traditional metallographic detection eccentricity method has many steps (inlaying→grinding→polishing→photographing detection), which takes a long time, and at the same time, the human er...
