Specifications for the re-use of sulphur hexafluoride (SF6) and its mixtures in electrical equipment
This document provides criteria for the re-use of sulphur hexafluoride (SF6) and its mixtures after recovery and reclaiming from electrical equipment (e.g. for maintenance, at the end-oflife). Sulphur hexafluoride (SF6), nitrogen (N2) and carbon tetrafluoride (CF4), are gases commonly used for electrical equipment. Taking into account environmental concerns, particular attention is paid to re-use criteria for SF6 and its mixtures with N2 and CF4 for its use in electrical equipment. Procedures for recovering and reclaiming used SF6 and its mixtures are outside the scope of this document and are described in IEC 62271-4. This document provides several annexes on the description of the different methods of analysis, on by-products, on the procedure for evaluating the potential health effects from byproducts, on cryogenic reclaiming of SF6, and on reclaiming recommendations. Storage, transportation and disposal of SF6 and its mixtures are outside the scope of this document and are covered by IEC 62271-4. Procedures to determine SF6 leakages are described in IEC 60068-2-17 [4]1. For the purposes of this document, the complementary gases used in SF6 mixtures will be limited to N2 or CF4.
Spezifikationen für die Wiederverwendung von Schwefelhexafluorid (SF6) und seinen Mischungen in elektrischen Betriebsmitteln
Spécifications pour la réutilisation de l’hexafluorure de soufre (SF6) et des mélanges contenant du SF6 dans le matériel électrique
Le présent document spécifie des critères de réutilisation de l’hexafluorure de soufre (SF6) et des mélanges contenant du SF6 après reprise et régénération depuis le matériel électrique(par exemple, pour la maintenance ou en fin de vie). L’hexafluorure de soufre (SF6), l’azote (N2) et le tétrafluorure de carbone (CF4) sont des gaz communément utilisés pour le matériel électrique. Une attention particulière est accordée aux critères de réutilisation du SF6 et de ses mélanges avec N2 et CF4 pour leur utilisation dans le matériel électrique, afin de prendre en compte les aspects d’environnement. Les procédures de reprise et de régénération du SF6 usagé et des mélanges contenant du SF6 usagé ne relèvent pas du domaine d’application du présent document. Elles sont décrites dans l’IEC 62271-4. Le présent document comprend plusieurs annexes qui décrivent les différentes méthodes d’analyse, traitent des sous-produits, de la procédure d’évaluation des effets potentiels des sous-produits sur la santé, de la régénération cryogénique du SF6 et donnent des recommandations relatives à la régénération. Les procédures de stockage, de transport et d’élimination du SF6 et des mélanges contenant du SF6 ne relèvent pas du domaine d’application du présent document. Elles sont décrites dans l’IEC 62271-4. Les procédures de détermination des fuites de SF6 sont décrites dans l’IEC 60068-2-17 [4]1. Pour les besoins du présent document, les gaz complémentaires utilisés dans les mélanges du SF6 sont limités à l’azote (N2) ou au tétrafluorure de carbone (CF4).
Specifikacija za ponovno uporabo žveplovega heksafluorida(SF6) in njegovih mešanic v električni opremi
Ta dokument vsebuje merila za ponovno uporabo žveplovega heksafluorida (SF6) in njegovih mešanic po predelavi in ponovnem pridobivanju iz električne opreme (npr. za vzdrževanje, ob koncu življenjske dobe). Žveplov heksafluorid (SF6), dušik (N2) in ogljikov tetrafluorid (CF4) so plini, ki se običajno uporabljajo za električno opremo. Ob upoštevanju okoljskih vprašanj je posebna pozornost namenjena kriterijem ponovne uporabe SF6 in njegovih mešanic z N2 in CF4 za njegovo uporabo v električni opremi. Postopki za predelavo in ponovno pridobivanje uporabljenega SF6 in njegovih mešanic ne spadajo na področje uporabe tega dokumenta in so opisani v standardu IEC 62271-4.
Ta dokument vsebuje več dodatkov o opisu različnih metod analize, stranskih proizvodih, postopku ocenjevanja možnih vplivov na zdravje iz stranskih proizvodov, kriogenem ponovnem pridobivanju SF6 in priporočilih za ponovno pridobivanje.
Shranjevanje, prevoz in odstranjevanje SF6 ter njegovih mešanic ne spadajo na področje uporabe tega dokumenta in so opisani v standardu IEC 62271-4. Postopki za določanje puščanja SF6 so opisani v standardu IEC 60068-2-17 [4]1.
V tem dokumentu so plini, uporabljeni v mešanicah SF6, omejeni na N2 ali CF4.
