IEC 60700-1:2015

Thyristor valves for high voltage direct current (HVDC) power transmission - Part 1: Electrical testing

IEC 60700-1:2015 applies to thyristor valves with metal oxide surge arresters directly connected between the valve terminals, for use in a line commutated converter for high voltage d.c. power transmission or as part of a back-to-back link. It is restricted to electrical type and production tests. The tests specified in this standard are based on air insulated valves. For other types of valves, the test requirements and acceptance criteria can be agreed. This edition includes the following significant technical changes with respect to the previous edition.
a) Definitions of terms "redundant thyristor levels", "thyristor level", "valve section" have been changed for clarification.
b) The notes were added to test requirements of dielectric d.c. voltage tests for valve support, MVU, valve, specifying that before repeating the test with opposite polarity, the tested object may be short-circuited and earthed for several hours. The same procedure may be followed at the end of the d.c. voltage test.
c) Table 1 on thyristor level faults permitted during type tests was supplemented.
d) The alternative MVU dielectric test method was added.
e) It was specified that production tests may include routine tests as well as sample tests.
f) It was added into test requirements for periodic firing and extinction tests that a scaling factor for tests shall be applied when testing with valve sections.
The contents of the corrigendum of January 2017 have been included in this copy.

Valves à thyristors pour le transport d'énergie en courant continu à haute tension (CCHT) - Partie 1: Essais électriques

IEC 60700-1:2015 s'applique aux valves à thyristors équipées de parafoudres à oxyde métallique directement connectés entre les bornes des valves, qui sont destinées à être utilisées au niveau d'un convertisseur commuté par le réseau pour le transport d'énergie en courant continu à haute tension ou dans une liaison dos à dos. Elle est limitée aux essais de type électriques et de série. Les essais spécifiés dans la présente norme sont basés sur des valves isolées par l'air. Pour d'autres types de valves, les exigences d'essai et les critères d'acceptation peuvent faire l'objet d'un accord. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente.
a) Les définitions des termes "niveaux de thyristors redondants", "niveau de thyristor", "section de valve" ont été modifiées dans un souci de clarification.
b) Des notes ont été ajoutées aux exigences des essais diélectriques sur support de valve sous tension continue, UVM, spécifiant qu'avant de répéter l'essai avec la polarité opposée, l'objet d'essai peut être court-circuité et mis à la terre pendant plusieurs heures. La même procédure peut être suivie à l'issue de l'essai sous tension continue.
c) Le Tableau 1 sur les défauts de niveaux de thyristors autorisés au cours des essais de type a été complété.
d) La méthode alternative pour les essais diélectriques UVM a été ajoutée.
e) Il a été spécifié que les essais de série peuvent inclure des essais individuels de série ainsi que des essais sur prélèvement.
f) Il a été ajouté dans les exigences pour les essais d'allumage et d'extinction périodiques qu'un facteur d'échelle pour les essais doit être appliqué lors des essais sur les sections de valve.
Le contenu du corrigendum de janvier 2017 a été pris en considération dans cet exemplaire.
