测定漆包和胶带缠绕绕组线温度指数的试验程序

[中文适用范围]： 本国际标准根据IEC 60216-1的规定，规定了一种在常压空气中通过定期监测交流耐压试验响应的变化来评估漆包线（无论是否含有浸渍剂）以及带包绕圆形和矩形线的温度指数的方法。本程序不适用于纤维绝缘线或覆盖有无机纤维带的线。 注：根据本试验程序获得的数据为设计人员和开发工程师提供了选择绕组线的信息，以便进一步评估绝缘系统和设备试验。 [外文原描述]： IEC 60172:2020 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 60172:2020 specifies, in accordance with the provisions of IEC 60216-1, a method for evaluating the temperature index of enamelled wire, varnished or unvarnished with an impregnating agent, and of tape wrapped round and rectangular wire, in air at atmospheric pressure by periodically monitoring changes in response to AC proof voltage tests. This procedure does not apply to fibre-insulated wire or wire covered with tapes containing inorganic fibres. NOTE The data obtained according to this test procedure provide the designer and development engineer with information for the selection of winding wire for further evaluation of insulation systems and equipment tests. This fifth edition cancels and replaces the fourth edition published in 2015. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - revision of 3.1, definition of thermal index; - revision of 3.3, time to failure; - revisions to 5.1.1 for clarity and to reduce the range wire size range to which the test applies; - revisions to 5.1.2 for tape wrapped round and enamelled or tape wrapped rectangular wire for clarity; - revision to Clause 9 to add the correlation coefficient, r to the report.
