往复式内燃机驱动的交流发电机组 第4部分：控制设备和开关设备

[中文适用范围]： 本文件规定了由往复式内燃机驱动的发电机组所用的控制设备和开关设备的标准。本文件适用于用于陆地和船舶上（不包括用于航空器或用于驱动陆地车辆和机车的发电机组）的交流（AC）发电机组。对于某些特定应用（如关键医疗设备和高层建筑），可能需要补充要求。本文件的规定可作为制定任何补充要求的基础。对于由其他原动机（如蒸汽机）驱动的发电机组，本文件也可作为制定相关要求的基础。 [外文原描述]： This document specifies the criteria for controlgear and switchgear for generating sets with reciprocating internal combustion engines. This document applies to alternating current (a.c.) generating sets driven by reciprocating internal combustion (RIC) engines for land and marine use excluding generating sets used on aircraft or to propel land vehicles and locomotives. For some specific applications (e.g. essential hospital supplies and high-rise buildings), supplementary requirements can be necessary. The provisions of this document serve as a basis for establishing any supplementary requirements. For generating sets driven by other prime movers (e.g. steam engines), this document serves as a basis for establishing requirements.
