标准摘要
[中文适用范围]： 本部分规定了分散式农村电气化系统中防止人员与设备遭受电危害的通用要求。涉及电击防护的要求基于IEC 61140和IEC 60364中的基本规则。分散式农村电气化系统（DRES）旨在为未连接大型互联系统或国家电网的地点供电，以满足基本需求。这些地点主要包括：孤立住宅、村庄房屋、社区服务设施（如公共照明、抽水、卫生中心、礼拜场所、文化场所、行政建筑等）以及经济活动场所（如车间、微型工业等）。DRE系统分为三类：过程电气化系统（如抽水）、个人电气化系统（IES，供单个用户）和集体电气化系统（CES，供多个用户）。过程或个人电气化系统由两个子系统组成：电能产生子系统和用户电气装置。集体电气化系统则由三个子系统组成：电能产生子系统、配电子系统（也称为微网）、以及用户电气装置（包括与微网之间的接口设备）。本部分规定的通用要求适用于所有识别的DRES类别。 [外文原描述]： IEC TS 62257-5:2015(E) specifies the general requirements for the protection of persons and equipment against electrical hazards to be applied in decentralised rural electrification systems. Requirements dealing with protection against electric shock are based on basic rules from IEC 61140 and IEC 60364. Decentralized Rural Electrification Systems are designed to supply electric power for sites which are not connected to a large interconnected system, or a national grid, in order to meet basic needs. Examples of such sites: isolated dwellings, village houses, community services, economic activities, etc. The main technical changes with regard to the previous edition are as follows: - redefine the maximum AC voltage from 500 V to 1 000 V, the maximum DC voltage from 750 V to 1 500 V; - removal of the limitation of 100 kVA system size. This publication is to be read in conjunction with IEC 62257 series .
