低压电气装置第8-1部分:功能性节能

[中文适用范围]： 本部分 IEC 60364 为所有类型低压电气装置的规划、安装、运行和验证提供了额外的要求、措施和建议，包括能源的本地生产和储存，旨在优化电力的整体高效利用。它在能源效率管理方法的框架内，引入了用于设计和评估电气装置能源效率（EE）的要求、建议和方​​法，以获得最佳的永久功能等效服务，同时将最低的电能量消耗、最可接受的能源可用性和经济平衡结合起来。这些要求、建议和方​​法适用于 IEC 60364（所有章节）范围内新建装置和现有装置的修改。本文档适用于建筑物的电气装置或系统，不适用于产品。产品的能源效率及其运行要求由相关的产品标准涵盖。如果另一项标准对特定系统或安装应用（例如由 ISO 50001 涵盖的制造系统）提供了特定要求，则这些要求可能取代本文档。本文档不具体解决楼宇自动化系统。本组能源效率出版物主要旨在作为上述第 1 条中提到的低压电气装置的能源效率标准，但也旨在供技术委员会在根据 IEC 指南 119 和 IEC 指南 118 中确立的原则制定标准时使用。 [外文原描述]： IEC 60364-8-1:2019 provides additional requirements, measures and recommendations for the design, erection and verification of all types of low-voltage electrical installation including local production and storage of energy for optimizing the overall efficient use of electricity. It introduces requirements and recommendations for the design of an electrical installation within the framework of an energy efficiency management approach in order to get the best permanent functionally equivalent service for the lowest electrical energy consumption and the most acceptable energy availability and economic balance. These requirements and recommendations apply, within the scope of the IEC 60364 series, for new installations and modification of existing installations. This standard is applicable to the electrical installation of a building or system and does not apply to products. The energy efficiency of these products and their operational requirements are covered by the relevant product standards. This standard does not specifically address building automation systems. This edition includes the following significant technical changes with respect to the previous edition: a) revision of Annex B; b) revision of 4.2: Energy efficiency assessment for electrical installations; c) update of 8.3: Input from loads, sensors and forecasts; d) introduction of new definitions. This group energy efficiency publication is primarily intended to be used as an energy efficiency standard for the low voltage electrical installations mentioned in Clause 1, but is also intended to be used by technical committees in the preparation of standards, in accordance with the principles laid down in IEC Guide 119 and IEC Guide 118. The contents of the corrigendum of May 2019 have been included in this copy.
