摘　　要：介绍了漆包线盐水针孔测试方法的发展历程、测试原理和设备,详细地表述了盐水针孔测试方法改良,即在漆包线盐水针孔测试前对漆包线进行一定量的预拉伸。经改良后的盐水针孔测试能准确反映下游厂家将漆包线绕制成线圈后漆膜的完好性。此外,对漆包线生产过程中发生盐水针孔的原因提出了整改措施。This article introduces the development process, test philosophy and experimental facilities of enameled wire brine pinhole test method, describes the improvements of brine pinhole test method in detail, which is that pre-stretching a certain amount before the pinhole test of enameled wire. The improved test can accurately reflect integrity of paint film after the downstream manufacturers made enameled wire winding coil. In addition, the improvement measures for the causes of brine pinhole appearance in the process of enameled wire production are proposed in this article.
