工业和住宅用时间继电器和耦合继电器 第1部分：要求和测试

[中文适用范围]： 本部分IEC 61812适用于工业应用（例如控制、自动化、信号和工业设备）以及用于住宅和类似用途设备的自动电气控制中的时间继电器和耦合继电器。 本文件中使用的“继电器”一词包括除测量继电器外所有类型的时间继电器和耦合继电器。 注1：时间继电器和耦合继电器可用于工业应用（例如控制、自动化、信号和工业设备）以及用于住宅和类似用途设备的自动电气控制。 注2：测量继电器由IEC TC95处理。 本文件定义了型式试验和例行试验以确认使用条件。第3.2条提供了IEC 61812系列中使用的时间继电器不同类型的定义。 [外文原描述]： IEC 61812-1:2023 applies to time relays and coupling relays for industrial applications (for example control, automation, signal and industrial equipment) and for automatic electrical controls for use in, on, or in association with equipment for residential and similar use. The term “relay” as used in this document comprises all types of time relays and coupling relays, other than measuring relays. This document defines type test and routine test to confirm the service condition. Subclause 3.2 provides definitions for different types of time relays in use in the IEC 61812 series. IEC 61812-1:2023 cancels and replaces the second edition published in 2011. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) update of references; b) addition of requirements for risk assessment; c) addition of requirements for routine test; d) renumbering of clauses to bring them into a more logical order; e) clarification of the requirement for shock; f) addition of cybersecurity requirements for industrial automation and control systems; g) addition of environmentally conscious design requirement; h) addition of common data dictionary reference; i) addition of terms and definitions of relay types; j) addition of coupling relays in title; k) addition of coupling relays in scope.
