电气设备中的矿物绝缘油.监督和维护指南

[中文适用范围]： 本国际标准为电气设备绝缘油质量的监督和维护提供指导。本标准适用于最初供应符合 IEC 60296 的矿物绝缘油，并用于变压器、开关设备和其他电气设备，其中油样取样是合理可行的，并且适用设备规范中规定的正常工作条件。该标准帮助电力设备操作员评估油的状况并将其保持在可用状态。它还为制定更具体、更完整的地方实践守则提供了共同基础。该标准包括有关测试和评估程序的建议，并概述了修复和回收油以及净化受 PCB 污染的油的方法。注：电气设备的状态监测，例如通过溶解气体、呋喃化合物或其他方法的分析，不属于本标准的范围。 [外文原描述]： Gives guidance on the supervision and maintenance of the quality of the insulating oil in electrical equipment. This standard is applicable to mineral insulating oils, originally supplied conforming to IEC 60296, and used 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 standard assists 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. This standard includes recommendations on tests and evaluation procedures and outlines methods for reconditioning and reclaiming oil and the decontamination of oil contaminated with PCB. NOTE The condition monitoring of electrical equipment, for example by analysis of dissolved gases, furanic compounds or other means is outside the scope of this standard. The main changes with regard to the previous edition are as follows: This standard has been revised to take into account changes in oil and equipment technology and to have due regard for the best practices currently in use world-wide. 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. This guidance incorporates changes introduced in associated standards since the publication of the second edition.
