自动电气控制设备 计时器和时间开关的特殊要求

[中文适用范围]： 本部分 IEC 60730 适用于： - 用于、安装在或与家用电器及类似用途设备关联的计时器和时间开关； - 在 ISO 16484 系列和 IEC 63044 系列（HBES/BACS）范围内的楼宇自动化； - 供公众使用的设备，例如用于商店、办公室、医院、农场以及商业和工业应用的设备； - 智能启用控制； - 额定电压不超过 690 V AC 或 600 V DC 的交流或直流供电控制； - 作为控制系统的一部分，或与具有非电气输出的多功能控制机械集成的控制； - 以及当手动控制与自动控制电气和/或机械集成时的手动控制。 本文件适用于： - 计时器和时间开关的固有风险； - 计时器和时间开关及其安全相关系统的功能安全； - 产品性能（例如电磁兼容现象的影响）可能损害受控系统整体安全和性能的计时器和时间开关； - 与设备安全相关的操作值、操作时间和操作序列； - IEC 60335 系列范围内的家电用计时器； - 当手动控制与计时器电气和/或机械集成时的手动控制。 本文件规定了用于、安装在或与设备关联的计时器和时间开关的构造、操作和测试要求。 本文件不适用于： - IEC 60669-2-3 范围内的延时开关（TDS）； - 仅指示时间或时间流逝的设备； - 具有集成计时功能但该功能无法作为独立计时设备进行测试的多功能控制。 [外文原描述]： IEC 60730-2-7:2026 applies to timers and time switches: - for use in, on, or in association with equipment for household appliance and similar use; NOTE 1 Throughout this document, the word "equipment" means "appliance and equipment" and "controls" means "timer or time switches". NOTE 2 Throughout this document, the word "timers" means timers and time switches, unless the type is specifically mentioned. - for building automation within the scope of ISO 16484 series and IEC 63044 series (HBES/BACS); - or equipment that is used by the public, such as equipment intended to be used in shops, offices, hospitals, farms and commercial and industrial applications; - that are smart enabled controls; - that are AC or DC powered controls with a rated voltage not exceeding 690 V AC or 600 V DC; - utilized as part of a control system or controls which are mechanically integral with multifunctional controls having non-electrical outputs; - as well as manual controls when such are electrically and/or mechanically integral with automatic controls. NOTE 3 Requirements for manually actuated mechanical switches not forming part of an automatic control are contained in IEC 61058-1-1. This document applies to - the inherent safety of timers and time switches, and - functional safety of timers and time switches and safety related systems, - timers and time switches where the performance (for example the effect of EMC phenomena) of the product can impair the overall safety and performance of the controlled system, - the operating values, operating times, and operating sequences where such are associated with equipment safety, - timers for appliances within the scope of IEC 60335 series. - manual controls when such are electrically and/or mechanically integral with timers. This document specifies the requirements for construction, operation and testing of timers and time switches used in, on, or in association with an equipment. This document does not - apply to time-delay switches (TDS) within the scope of IEC 60669-2-3; - include devices which only indicate time or passage of time; - apply to multi-functional controls having an integrated timing function which is not capable of being tested as a separate timing device. This fourth edition cancels and replaces the third edition published in 2015. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: adoption of IEC 60730-1:2022 (Ed.6.0) with all of its significant changes to IEC 60730 1:2010 (Ed.4). This part 2-7 is intended to be used in conjunction with IEC 60730-1. It was established on the basis of the sixth edition of that standard (2022). Consideration can be given to future editions of, or amendments to, IEC 60730 1. This part 2-7 supplements or modifies the corresponding clauses in IEC 60730-1, so as to convert that publication into the IEC standard: Particular requirements for timers and time switches. Where this part 2-7 states "addition", "modification" or "replacement", the relevant requirement, test specification or explanatory matter in part 1 should be adapted accordingly. Where no change is necessary, part 2-7 indicates that the relevant clause or subclause applies
