爆炸性环境 第 17 部分：电气装置检查和维护

[中文适用范围]： 本部分IEC 60079适用于用户，仅涵盖与专门为危险区域设计的电气装置的检查和维护直接相关的因素，其中危险由爆炸性环境引起。不包括： • 电气装置的其他基本安装和检查要求； • 电气设备的验证； • 房间的保护或通风； • 气体检测系统； • 爆炸防护设备的修理、大修和回收（见IEC 60079-19）。 本文件不包括通风房间中使用的安全装置的检查（见IEC 60079-13），但包括对此类系统组成部分的个别设备（如电机或传感器）的检查和维护要求。 本文件补充了IEC 60364-6中非危险区域的检查和测试要求。本文件旨在应用于存在爆炸性气体或粉尘混合物与空气或可燃粉尘层在正常大气条件下存在风险的情况下。不适用于： • 地下采矿区域； • 爆炸性粉尘； • 自燃物质。 [外文原描述]： IEC 60079-17:2023 applies to users and covers only those factors directly related to the inspection and maintenance of electrical installations specifically designed for hazardous areas, where the hazard is caused by explosive atmospheres. It does not include: - other fundamental installation and inspection requirements for electrical installations; - the verification of electrical equipment; - protection or ventilation of rooms; - gas detection systems; - the repair, overhaul and reclamation of explosion protected equipment (see IEC 60079-19). While this document does not include inspection of safety devices such as used in ventilated rooms (see IEC 60079-13), it does include the requirements for inspection and maintenance of individual items of equipment that will be part of such systems, for example motors or sensors. This document supplements the requirements for inspection and testing in non-hazardous areas in IEC 60364-6. This document is intended to be applied where there is a risk due to the potential presence of explosive gas or dust mixtures with air or combustible dust layers under normal atmospheric conditions. It does not apply to: - underground mining areas, - dusts of explosives, - pyrophoric substances. This sixth edition cancels and replaces the fifth edition published in 2013. This edition constitutes a technical revision.
