IEC 61643-341:2020规定了晶闸管浪涌抑制器（TSS）元件的标准测试电路和方法。这些浪涌保护元件SPC是特殊配方的晶闸管，旨在通过箝位和开关动作来限制过电压和转移浪涌电流。这些SPC用于构建电压高达交流1 000 V和DC 1 500 V的电涌保护装置（SPD）和信息通信技术（ICT）网络中使用的设备。本文档适用于具有阻断、导通或开关第三象限（-v和-i）特性的门控或非门控TSS组件。本文档包含以下信息 -术语； -字母符号； -基本评级和特征； -额定值验证和特性测量； 本文件不适用于常规三-IEC 60747-6涵盖的端子晶闸管。IEC 61643-341的第二版取消并取代了2001年发布的第一版。本版构成技术修订版。与上一版相比，该版本包括以下重大技术变化:增加了性能值。

IEC 61643-341:2020 specifies standard test circuits and methods for thyristor surge suppressor (TSS) components. These surge protective components, SPCs, are specially formulated thyristors designed to limit overvoltages and divert surge currents by clamping and switching actions. These SPCs are used in the construction of surge protective devices (SPDs) and equipment used in Information & Communications Technologies (ICT) networks with voltages up to AC 1 000 V and DC 1 500 V. This document is applicable to gated or non-gated TSS components with third quadrant (-v and –i) characteristics of blocking, conducting or switching. This document contains information on
- terminology;
- letter symbols;
- essential ratings and characteristics;
- rating verification and characteristic measurement;
This document does not apply to the conventional three-terminal thyristors as covered by IEC 60747-6. This second edition of IEC 61643-341 cancels and replaces the first edition published in 2001. This edition constitutes a technical revision.This edition includes the following significant technical changes with respect to the previous edition: Addition of performance values.
