标准摘要
[中文适用范围]： 本部分IEC 61820规定了航空地面照明中由串联电路供电的灯具系统的防护措施。 此处描述的防护措施仅适用于与串联电路电气隔离的负载的二次供电系统。 本文件考虑了电气熟练人员在带电二次回路上工作时的额外人员保护，规定了SELV水平，或替代的PELV水平。本文件还涵盖了航空地面照明的特殊操作特性，并涉及IEC 61821中详述的培训水平和维护程序要求以及其他国家或地区法规。 要求和测试旨在为系统设计者、系统安装者、用户和维护人员建立一个规范框架，以确保机场信标装置中电气系统的安全和经济使用。 本文件是对现有IEC航空地面照明(AGL)标准的补充，可用作设计规范。 [外文原描述]： IEC 61820-3-4:2023 specifies protective provisions for the operation of lamp systems powered by series circuits in aeronautical ground lighting. The protective provisions described here refer only to secondary supply systems for loads that are electrically separated from the series circuit. This document specifies the level of SELV, and alternatively PELV, under consideration of additional personnel protection during work on live secondary circuits by electrically skilled persons. This document also covers the special operational features of aeronautical ground lighting and addresses the level of training and the requirements for maintenance procedures detailed in IEC 61821 and other national or regional regulation. The requirements and tests are intended to set a specification framework for system designers, system installers, users, and maintenance personnel to ensure a safe and economic use of electrical systems in installations for the beaconing of aerodromes. This document complements existing IEC aeronautical ground lighting (AGL) standards and can be used as a design specification.
