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。

GB/T 20840.8-2007互感器 第8部分:电子式电流互感器

本部分适用于新制造的电子式电流互感器，它具有模拟量电压输出或数字量输出，供频率为15Hz～10OHz的电气测量仪器和继电保护装置使用。 第 12 章所列的准确度要求，适用于电气测量仪器用电子式电流互感器。 第 13 章所列的准确度要求，适用于继电保护装置用电子式电流互感器，特别是那些以电流达额定电流很多倍时仍保持其准确度为主要要求的保护方式。如有要求，电子式电流互感器在电力系统故障时的暂态准确度也列于本章。 测量和保护两用的电子式电流互感器应遵循本部分的所有条款，且被称为多用途电子式电流互感器。 这种互感器技术可以用带有电子器件的光学装置，采用空心线圈（有或无内置积分器）或内装并联电阻的铁心线圈作为电流变电压的转换器，它们可单独使用或配装电子器件。 对于模拟量输出，电子式电流互感器可包括二次信号电缆。采用空心线图及内装并联电阻的铁心线圈的电子式电流互感器技术实例，列于附录 D 。 对于数字量输出，本部分采纳电子式互感器到电气测量仪器和电气装置为点对点链接（见附录 E）。 为了保证这种点对点链接对整个变电站通讯系统的兼容性，从而允许所有各类变电站装置之间的数据交换，增加了一些内容。这些内容建立了所谓点对点串行链接的链路层映射。总线通讯正在考虑中。 此映射允许不同制造单位的设备可以交互使用。 本部分既不规定特定的实施方案或产品，也不限定计算机系统的各种实施方案和接口。本部分规定各种实施方案的外部可见功能，以及这些功能所应遵守的要求。

DIN EN 1012-3-2014压缩机和真空泵. 安全要求. 第3部分:加工压缩机; 德文版本EN 1012-3-2013

This part of EN 1012 is applicable to compressors having an operating pressure greater than 0,5 bar and designed to utilise all gases other than air, nitrogen or inert gases which are covered in part 1. The standard lists the significant hazards associated with compressors and specifies safety requirements applicable to the design, installation, operation, maintenance and dismantling of compressors during their foreseeable lifetime and subsequent disposal.This part of EN 1012 includes under the general term compressors, those machines which comprise;- the compressor itself- a prime mover- any component or device supplied which is necessary for safe operation of the compressor.In addition it applies to partly completed compressors having a compressor in combination with some of these components as well as compressor assemblies operating in combination.Excluded are refrigerant compressors used in refrigerating systems or heat pumps as defined in EN 378-1.

BS EN 60044-8-2002仪表变压器.电流变压器

This part of IEC 60044 applies to newly manufactured electronic current transformers havingan analogue voltage output or a digital output, for use with electrical measuring instrumentsand electrical protective devices at nominal frequencies from 15 Hz to 100 Hz.NOTE Additional requirements due to the bandwidth are considered. The accuracy requirements on harmonics aregiven in annex D.Clause 12 covers the accuracy requirements that are necessary for electronic currenttransformers for use with electrical measuring instruments.Clause 13 covers the accuracy requirements that are necessary for electronic currenttransformers for use with electrical protective relays, and particularly for forms of protection inwhich the prime requirement is to maintain the accuracy up to several times the rated current.If required, the transient accuracy of an electronic current transformer during fault is also givenin this clause.Electronic current transformers intended for both measurement and protection should complywith all the clauses of this standard and are called multipurpose electronic currenttransformers.The transformer technology can be based on optical arrangements equipped with electricalcomponents, on air-core coils (with or without a built-in integrator), or on iron-core coils withintegrated shunt used as a current-to-voltage converter, alone or equipped with electroniccomponents.For analogue output, the electronic current transformer may include the secondary signalcable. Examples of electronic current transformer technologies using air-core coils and ironcorecoils with integrated shunt are given in annex C.For digital output, this standard takes into account a point-to-point connection from theelectronic transformer to electrical measuring instruments and electrical devices (see annex B).Some information has been added in order to ensure the compatibility of this point-to-point linkwith the overall system of communication in the substation, thus allowing data exchangebetween all kinds of substation devices. This information builds what is called the mapping ofthe link layer of the point-to-point serial link. Processbus communication is underconsideration.This mapping allows interoperability between devices from different manufacturers.This standard does not specify individual implementations or products, nor does it constrain theimplementation of entities and interfaces within a computer system. This standard specifies theexternally visible functionality of implementations together with conformance requirements forsuch functionalities.
