电气设备中的矿物绝缘油 监督和维护指南

[中文适用范围]： 本文件提供了矿物绝缘油和其他基于碳氢化合物的液体在变压器和其他电气设备中使用和维护所需的监测指导和程序，包括战略备件和存放备件和组件的储罐。 本文件适用于变压器、开关设备和其他电气设备中最初符合IEC 60296的矿物绝缘油，在这些设备中油样采集是合理可行的，并且设备规格中规定的正常运行条件适用。 本文件还旨在协助电力设备操作员评估油的状态并保持其可用状态。它还提供了一个共同基础，用于制定更具体和完整的本地操作规范。 该文件包括关于测试和评估程序的建议，并概述了油的再处理和回收方法，以及被多氯联苯污染的油的去污方法。 注：电气设备的状态监测，例如通过分析溶解气体、呋喃化合物或其他方法，不在本文件的范围内。 [外文原描述]： IEC 60422:2024 provides monitoring guidance and procedures that are required for the use and maintenance of mineral insulating oils and other hydrocarbon-based liquids in transformers and other electrical equipment, including strategic spares and tanks for holding spare parts and components. This document 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 document 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 document includes recommendations on tests and evaluation procedures, and outlines methods for reconditioning and reclaiming oil, and the decontamination of oil contaminated with PCBs. 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 document.
