GB/T 14598.26-2015量度继电器和保护装置第26部分:电磁兼容要求

概述GB/T 14598的本部分适用于电力系统保护所用的量度继电器和保护装置，包括与这些装置一起使用的控制、监视、通信和过程接口设备。本部分规定了量度继电器和保护装置的电磁兼容要求。对于不含有电子电路的装置，例如机电式继电器，不要求做本部分规定的试验。本部分的各项要求适用于新的量度继电器和保护装置，所规定的所有试验仅为型式试验。发射本部分规定了量度继电器和保护装置可能对其他设备产生干扰的电磁发射限值和试验方法。本部分所选择的发射限值表明了电磁兼容的要求，以确保工作在变电站和发电厂中的量度继电器和保护装置所产生的骚扰不会超出规定的试验等级而妨碍其他设备的正常工作。这些试验要求是为量度继电器和保护装置的外壳和辅助电源端口规定的。抗扰度本部分规定了与连续的和瞬时的传导骚扰、辐射骚扰以及静电放电有关的量度继电器和保护装置的抗扰度试验要求。这些试验要求阐明了电磁兼容的抗扰度要求，以确保变电站和发电厂中正常运行的量度继电器和保护装置具有足够的抗扰度水平。

GB/T 20840.6-2017互感器第6部分:低功率互感器的补充通用技术要求

GB/T 20840的本部分规定了额定频率为15 Hz~100 Hz的交流用途或直流用途的低功率互感器(LPIT)的补充通用技术要求。本产品标准以GB/T 20840.1为基础，对相关的专项标准的条款进行了增补。本部分不包括互感器数字量输出格式的技术规范。本部分限定了模拟量或数字量输出的误差。互感器数字接口的其他特性见GB/T 20840.9，并应用了变电站分层通讯结构的系列标准。本部分考虑了涉及带宽的补充要求。谐波准确度要求和抗混叠滤波器要求列于附录6A.4中。单相LPIT的通用框图见图601。依据采用的技术，并非图601列出的所有部件皆为互感器必不可缺的。例如，对于无源低功率互感器(不包含有源电子器件的LPIT)，各框块仅由无源元件构成且无电源。

YD/T 1817-2017通信设备用直流远供电源系统

本标准规定了通信设备用直流远供电源系统(以下简称远供系统)的术语和定义、组成和分类、要求、试验方法、检验规则，以及标志、包装、运输和贮存。本标准适用于通过电力电缆、通信电缆进行直流电能远距离传送和接收的供电系统。本标准不适用于采用TNV电路供电的远供系统。

BS EN 61131-2-2007可编程控制器.第2部分:设备要求和试验

This part of IEC 61131 specifies requirements and related tests for programmable controllers(PLCs) and their associated peripherals (for example, programming and debugging tools(PADTs), human-machine interfaces (HMIs), etc.) which have as their intended use thecontrol and command of machines and industrial processes.PLCs and their associated peripherals are intended to be used in an industrial environmentand may be provided as open or enclosed equipment. If a PLC or its associated peripheralsare intended for use in other environments (light industrial, commercial, residential), then thespecific requirements, standards and installation practices for those other environmentsshould be additionally applied to the PLC and its associated peripherals.This standard also applies to any products performing the function of PLCs and/or theirassociated peripherals.Equipment covered in this standard is intended for use in overvoltage category II (IEC 60664-1)in low-voltage installations, where the rated equipment supply voltage does not exceed a.c.1 000 V r.m.s. (50/60 Hz), or d.c. 1 500 V. (If PLCs or their associated peripherals are appliedin overvoltage category III installations, then additional analysis will be required to determinethe suitability of the equipment for those applications.)This standard does not deal with the functional safety or other aspects of the overallautomated system. PLCs, their application programme and their associated peripherals areconsidered as components of a control system.Since PLCs are component devices, safety considerations for the overall automated systemincluding installation and application are beyond the scope of this standard. Refer toIEC 60364-1 or applicable national/local regulations for electrical installation and guidelines.However, PLC safety as related to electric shock and fire hazards, electrical interferenceimmunity and error detecting of the PLC-system operation (such as the use of parity checking,self-testing diagnostics, etc.), are addressed.This standard also specifiesa) service, storage and transportation requirements for PLCs and their associatedperipherals (Clause 4);b) functional requirements for PLCs and their associated peripherals (Clause 5);c) EMC requirements for PLCs and their associated peripherals (Clause 8);
