Anotation

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. IEC 61643-341:2020 specifie les circuits dessai et les methodes normalises pour les composants de parafoudre a thyristor (TSS, Thyristor Surge Suppressor). Ces composants de protection contre les surtensions (SPC, Surge Protective Components) sont des thyristors specialement concus pour limiter les surtensions et ecouler les courants de surcharge par des actions decretage et de commutation. Ces SPC sont utilises dans la construction de parafoudres (SPD, Surge Protective Devices) et dequipements utilises dans les reseaux de technologies de linformation et de la communication (TIC) dont les tensions atteignent 1 000 V CA et 1 500 V CC. Le present document sapplique aux composants TSS a gachette ou non, equipes dun troisieme quadrant (-v et –i) ayant des caracteristiques de blocage, de conduction ou de commutation. Le present document contient des indications sur: - la terminologie; - les symboles litteraux; - les valeurs assignees et les caracteristiques essentielles; - la verification des valeurs assignees et la mesure des caracteristiques. Le present document ne sapplique pas aux thyristors conventionnels a trois bornes couverts dans lIEC 60747-6. Cette deuxieme edition de lIEC 61643-341 annule et remplace la premiere edition parue en 2001. Cette edition constitue une revision technique. Cette edition inclut la modification technique majeure suivante par rapport a ledition precedente: Ajout de valeurs de performances.
