BS PD IEC/TS 62257-5:2015规定了人员和设备保护的一般要求 用于分散农村电气化的电气危害防护设备 系统。有关电击防护的要求基于基本要求 IEC 61140和IEC 60364中的规则。分散式农村电气化系统（DRES）旨在为农村供电 在国家电网中，哪一个站点与大型电网不相连 满足基本需求。这些场所中的大多数是:孤立的住宅、村舍、社区服务（公共照明、抽水、医疗中心、礼拜场所或文化场所） 经济活动（车间、微型工业等）。DRE系统分为三类:工艺电气化系统（例如泵送）、单个用户的单独电气化系统（IES）、多个用户的集体电气化系统（CES）。 工艺或单个电气化系统专门由两个子系统组成:一个发电子系统，用户的电气装置。然而，集体电气化系统由三个子系统组成:发电子系统、配电子系统（也称为微电网）、用户电气装置，包括装置和系统之间的接口设备 微电网。IEC 62257本部分规定的一般要求应适用于所有 确定了DRE的类别。DRES的每个子系统的应用程序在 IEC TS 62257-9的特定子部分。交叉引用:IEC 60364-4-41IEC 60364-4-43IEC 60364-4-44:2007IEC 60364-4-44:2007/AMD1:2015IEC 60364-5-52:2009IEC 60364-5-53:2001IEC 60364-5-53:2001/AMD1:2002IEC 60364-5-53:2001/AMD2:2015IEC 60364-5-54IEC 60364-7-712IEC 62305-2:2010IEC 62305-3:2010IEC 61140:2015IEC 62257-1EC 62257-62257- 4.IEC T6075 IEC 6066 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 IEC 62257-9IEC 62305IEC 62423所有现行修正案购买本文件时提供的信息包括在内。

BS PD IEC/TS 62257-5:2015 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 (DRES) 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.The majority of these sites are:isolated dwellings,village houses,community services (public lighting, pumping, health centers, places of worship or cultural activities, administrative buildings, etc.),economic activities (workshops, micro-industry, etc.).The DRE systems fall into three categories:process electrification systems (for example for pumping),individual electrification systems (IES) for single users,collective electrification systems (CES) for multiple users.Process or individual electrification systems exclusively consist of two subsystems:an electric energy generation subsystem,the user's electrical installation.Collective electrification systems, however, consist of three subsystems:an electric energy generation subsystem,a distribution subsystem, also called microgrid,user's electrical installations including interface equipment between the installations and the microgrid.The general requirements specified in this part of IEC 62257 should be applied to all the identified categories of DRES. Application to each subsystem of a DRES is dealt within a specific subpart of IEC TS 62257-9.Cross References:IEC 60364-4-41IEC 60364-4-43IEC 60364-4-44:2007IEC 60364-4-44:2007/AMD1:2015IEC 60364-5-52:2009IEC 60364-5-53:2001IEC 60364-5-53:2001/AMD1:2002IEC 60364-5-53:2001/AMD2:2015IEC 60364-5-54IEC 60364-7-712IEC 62305-2:2010IEC 62305-3:2010IEC 61140:2015IEC TS 62257-1IEC TS 62257-2IEC TS 62257-3IEC TS 62257-4IEC TS 62257-6IEC 60050-826:2004IEC 60364-1:2005IEC 60664-1:2007IEC TR 60755IEC 60898-1IEC 60947-2:2006IEC 60947-2:2006/AMD1:2009IEC 60947-2:2006/AMD2:2013IEC 61008-1:2010IEC 61008-1:2010/AMD1:2012IEC 61008-1:2010/AMD2:2013IEC 61009-1:2010IEC 61009-1:2010/AMD1:2012IEC 61009-1:2010/AMD2:2013IEC 61439-1IEC 61643-11IEC 61643-12IEC TR 62066IEC 62257-9IEC 62305IEC 62423All current amendments available at time of purchase are included with the purchase of this document.
