电量计量.支付系统.第31部分:特殊要求.有功电能静态支付表（0,5,1和2级）

[中文适用范围]： 本部分 IEC 62055 适用于新制造的、精度等级为 0.5、1 和 2 的静态瓦时付费电表，用于直接连接，测量频率在 45 Hz 至 65 Hz 范围内的交流电能耗，包括用于根据付费电表中当前可用信用值中断或恢复电力供应的负载供应控制开关。不适用于连接端子电压超过 600 V（多相系统的线间电压为 1000 V）的静态瓦时付费电表。 适用于仅用于室内应用的付费电表，在正常气候条件下运行，电表应按照正常服务安装（即与指定的匹配插座一起安装，如适用）。 付费电表是所有主要功能元件集成在一个外壳中的实现，包括任何指定的匹配插座。还有多部分多设备的付费计量安装，其中各种主要功能元件（如测量元件、用户界面单元、令牌载体接口和负载供应控制开关）在多个外壳中实现，涉及额外的接口。本部分 IEC 62055 不适用于多部分付费计量安装。 本文件还定义了适用于付费电表的功能要求，包括附录 A 中预付费操作模式的基本功能要求和测试。考虑到实践中可能出现的广泛功能、选项、替代方案和实现。付费电表的多样性和功能使得无法全面指定所有这些要求的详细测试方法。然而，在这种情况下，要求以可以制定测试的方式来验证所测试的付费电表的特定功能。 本文件不涵盖通过参考其他规范或标准可能指定的安全、电路保护、隔离或类似目的的特定功能或性能要求。第 1.0 版中删除的安全要求已被替换为对 IEC 62052-31:2015（新制造电表的产品安全标准）中包含的安全要求的引用。在役安全测试（ISST）不在 IEC 62052-31:2015 范围内，通常作为现有在役测试（IST）的扩展由各国最佳实践决定。 本文件不涵盖软件要求。基本能量表计量的软件要求在 IEC 62059 系列标准和其他组织中正在考虑。 本文件仅涵盖型式测试要求。对于验收测试，可以使用 IEC 61358 IEC 62058-11:2008 和 IEC 62058-31:2008 中给出的概念要求作为基本指南。 可靠性方面在 IEC 62059 系列标准中解决。IEC TC 56 提供了额外的可靠性、可用性、维护和生命周期方面。 [外文原描述]： IEC 62055-31:2022 CMV contains both the official standard and its commented version. The commented version provides you with a quick and easy way to compare all the changes between IEC 62055-31:2022 edition 2.0 and the previous IEC 62055-31:2005 edition 1.0. Furthermore, comments from IEC TC 13 experts are provided to explain the reasons of the most relevant changes, or to clarify any part of the content. IEC 62055-31:2022 applies to newly manufactured, static watt-hour payment meters of accuracy classes 0,5, 1 and 2 for direct connection, for the measurement of alternating current electrical energy consumption of a frequency in the range 45 Hz to 65 Hz that include a supply control switch for the purpose of interruption or restoration of the electricity supply to the load in accordance with the current value of the available credit maintained in the payment meter. It does not apply to static watt-hour payment meters where the voltage across the connection terminals exceeds 1 000 V (line-to-line voltage for meters for polyphase systems). It applies to payment meters for indoor application, operating under normal climatic conditions where the payment meter is mounted as for normal service (i.e. together with a specified matching socket where applicable). Payment meters are implementations where all the main functional elements are incorporated in a single enclosure, together with any specified matching socket. There are also multi-device payment metering installations where the various main functional elements, such as the measuring element, the user interface unit, token carrier interface, and the supply control switch are implemented in more than one enclosure, involving additional interfaces. Functional requirements that apply to payment meters are also defined in this document, and include informative basic functional requirements and tests for the prepayment mode of operation in Annex A. Allowances are made for the relatively wide range of features, options, alternatives, and implementations that may be found in practice. The diverse nature and functionality of payment meters prevent the comprehensive specification of detailed test methods for all of these requirements. However, in this case, the requirements are stated in such a way that tests can then be formulated to respect and validate the specific functionality of the payment meter being tested. This document does not cover specific functionality or performance requirements for circuit protection, isolation or similar purposes that may be specified through reference to other specifications or standards. Safety requirements removed from Edition 1.0 have been replaced with references to the safety requirements now contained in IEC 62052-31:2015, the product safety standard for newly manufactured electricity meters. In-service safety testing (ISST) is not covered by IEC 62052-31:2015 and is left to national best practice usually as an extension of existing in-service testing (IST) of metrology stability. This document does not cover software requirements. This document covers type-testing requirements only. For acceptance testing, the requirements given in IEC 62058‑11:2008 and IEC 62058-31:2008 may be used. Dependability aspects are addressed in the IEC 62059 series of standards. Additional reliability, availability, maintenance and life cycle aspects are provided by IEC TC 56. This document does not cover conformity tests and system compliance tests that may be required in connection with legal or other requirements of some markets. This second edition cancels and replaces the first edition published in 2005. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) Title modified. b) Removal of the contents of Annex C relating to the requirements for the supply control switch, and added reference to IEC 62052-31:2015 which contains the r
