标准范围

IEC TS 62257-5:20 15（E）规定了分散式农村电气化系统中保护人员和设备免受电气危害的一般要求。关于电击防护的要求基于IEC 61140和IEC 60364的基本规则。分散式农村电气化系统旨在为未连接到大型互联系统或国家电网的站点供电，以满足基本需求。这类地点的例子:独立住宅、村屋、社区服务、经济活动等。与上一版相比，主要技术变化如下:-将最大AC电压从500V重新定义为1000V，将最大DC电压从750V重新定义为1500V；-取消100千伏安系统规模的限制。本出版物应与IEC 62257系列一起阅读。

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.
