标准范围

IEC 62314:2022适用于称为固态继电器的特定全有或全无电气继电器，其旨在通过在断开状态和接通状态之间改变电路的状态来执行电气操作，反之亦然。本文件涉及打算结合到其他产品或设备中的固态继电器。因此，固态继电器被认为是组件，并且本文件定义了固态继电器作为独立组件的基本安全相关和功能要求。这种固态继电器被结合在产品或设备中，这些产品或设备本身符合相关产品和/或应用标准以满足其预期应用。作为装置的固态继电器:固体-状态继电器被指定为对最终用户具有功能的设备，本文件中给出了EMC要求。固态继电器作为组件:设备制造商对打算纳入设备的固态继电器没有EMC要求，因为性能很大程度上取决于设备中的应用。本文件的目的是说明:-固态继电器的特点-适用于固态继电器的规定a)电气安全；b)它们的操作和行为；c)它们的介电性质；d)EMC；-验证满足要求的试验，以及拟采用的试验方法；-固态继电器或产品文档中提供的信息。固体-具有单片结构的状态开关器件属于IEC分委会47E的范围，本文件不涉及。半导体控制器和接触器属于IEC小组委员会121A制定的IEC 60947系列标准——低压开关设备和控制设备的范围，不在本文档中。IEC 62314:2022取消并取代了2006年发布的第一版。本版构成技术修订版。与上一版相比，此版本包括以下重大技术变更:a)增加DC负载的负载类别；b)增加用于自镇流灯负载的负载类别；c)增加“插座”端子；d)参考文献的更新；e)介绍EMC的要求；f)整个文件的重组。

IEC 62314:2022 applies to particular all-or-nothing electrical relays denominated solid-state relays intended for performing electrical operations by single step function changes to the state of electric circuits between the OFF-state and the ON-state and vice versa.
This document deals with solid-state relays which are intended for incorporation in other products or equipment. As such, solid-state relays are considered to be components and this document defines the basic safety-related and functional requirements for solid-state relays as stand-alone components.
Such solid-state relays are incorporated in products or equipment which themselves comply with the relevant product and/or application standard(s) to meet their intended application.
Solid state relay as apparatus:
Where the solid-state relay is specified as apparatus with a function to the end-user, requirements on EMC are given in this document.
Solid state relay as component:
There are no EMC requirements for solid-state relays intended for incorporation into the equipment by the equipment manufacturer, because the performance strongly depends on the application into the equipment.
The object of this document is to state:
– the characteristics of solid-state relays
– the requirements which apply to solid-state relays with reference to
a) electrical safety;
b) their operation and behaviour;
c) their dielectric properties;
d) EMC;
– the tests verifying that the requirements have been met, and the test methods to be adopted;
– the information to be given with the solid-state relay or in the product documentation.
Solid-state switching devices with monolithic structures fall within the scope of IEC sub-committee 47E and are not covered in this document.
Semiconductor controllers and contactors fall within the scope of the IEC 60947 series of standards – low-voltage switchgear and controlgear – developed by IEC subcommittee 121A and are not covered in this document.
IEC 62314:2022 cancels and replaces the first edition published in 2006. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) addition of load categories for DC load;
b) addition of load category for self-ballasted lamp load;
c) addition of "sockets" terminal;
d) update of references;
e) introduction of the requirement of EMC;
f) restructuring of the whole document.
