电气设备中的矿物绝缘油.监督和维护指南

[中文适用范围]： 本国际标准提供了关于电气设备中绝缘油质量监督和维护的指导。本标准适用于最初符合IEC 60296标准的矿物绝缘油，用于变压器、开关设备和其他电气设备，且在这些设备中取样是切实可行的，并适用设备规范中规定的正常运行条件。本标准还旨在协助电力设备运营商评估油的状态并将其保持在可使用的状态。它也为制定更具体和完整的本地操作规程提供了共同基础。该标准包括有关测试和评估程序的推荐，并概述了油再处理、再生以及含多氯联苯（PCB）油去污染的方法。注：电气设备状态监测（例如通过溶解气体分析、糠醛化合物分析或其他手段）不属于本标准的范围。 [外文原描述]： IEC 60422:2013 gives guidance on the supervision and maintenance of the quality of the insulating oil in electrical equipment. This International Standard is applicable to mineral insulating oils, originally supplied conforming to IEC 60296, in transformers, switchgear and other electrical apparatus where oil sampling is reasonably practicable and where the normal operating conditions specified in the equipment specifications apply. This International Standard is also intended to assist the power equipment operator to evaluate the condition of the oil and maintain it in a serviceable condition. It also provides a common basis for the preparation of more specific and complete local codes of practice. The standard includes recommendations on tests and evaluation procedures and outlines methods for reconditioning and reclaiming oil and the decontamination of oil contaminated with PCBs. This fourth edition cancels and replaces the third edition, published in 2005, and constitutes a technical revision. The main changes with respect to the previous edition are as follows: - This new edition represents a major revision of the third edition, in order to bring in line this standard with latest development of oil condition monitoring, containing new limits for oil parameters, suggested corrective actions in the tables and new test methods. - The action limits for all oil tests have been revised and changes made where necessary to enable users to use current methodology and comply with requirements and regulations affecting safety and environmental aspects. - In addition, this standard incorporates changes introduced in associated standards since the third edition was published. The contents of the corrigendum of December 2013 have been included in this copy.
