Grading capacitors for high-voltage alternating current circuit-breakers - Part 1: General

IEC 62146-1:2013 is applicable to grading capacitors used on circuit-breakers. Their function is to control the voltage distribution across the individual interrupter units of a multi-break circuit-breaker. Grading capacitors can also be used in parallel to the interrupter unit on single break circuit-breakers to modify the Transient Recovery Voltage (TRV). The grading capacitor is a sub-component for the circuit-breaker and shall be specified in accordance with the circuit-breaker specifications. This standard applies to grading capacitors falling into one or both of the following categories for: - mounting on air-insulated circuit-breakers; - mounting on enclosed circuit-breakers (for example immersed in SF6, in oil, etc.). The testing for each of the above applications is in some cases different. The object of this standard is: - to define uniform rules regarding performances, testing and rating; - to define specific safety rules; - to provide a guidance for installation and operation. Keywords: grading capacitors, circuit-breakers

Condensateurs de répartition pour disjoncteurs à courant alternatif haute tension - Partie 1: Généralités

La CEI 62146-1:2013 s'applique aux condensateurs de répartition utilisés sur les disjoncteurs. Ces condensateurs ont pour fonction de contrôler la répartition de la tension entre chaque interrupteur d'un disjoncteur à coupure multiple. Les condensateurs de répartition peuvent également être utilisés parallèlement à l'interrupteur de disjoncteurs à coupure unique afin de modifier la tension transitoire de rétablissement (TRV - Transient Recovery Voltage). Le condensateur de répartition est un sous-composant du disjoncteur et il est spécifié conformément aux spécifications des disjoncteurs. La présente norme s'applique aux condensateurs de répartition à l'huile, à gaz et céramique relevant de l'une ou des deux catégories suivantes pour: - l'installation sur les disjoncteurs isolés dans l'air; - l'installation sur des disjoncteurs protégés (par exemple, immergés dans du gaz SF6, dans l'huile, etc.). L'essai applicable à chacune des applications susmentionnées est différent dans certains cas. La présente norme a pour objet de: - définir des règles uniformes concernant les performances, essais et caractéristiques assignées; - définir des règles de sécurité spécifiques; - fournir un guide d'installation et d'exploitation. Mots clés: Le condensateur de repartition, disjoncteurs

Kondenzatorji za izravnavo potenciala pri visokonapetostnih odklopnikih za izmenični tok - 1. del: Splošno (IEC 62146-1:2013)

Serija standardov EN-IEC 62146-1 se uporablja za kondenzatorje za izravnavo potenciala, ki se uporabljajo pri odklopnikih. Njihova naloga je, da nadzorujejo napetostne razdelilne sisteme v posameznih prekinitvenih enotah večprekinitvenega odklopnika. Kondenzatorji za izravnavo potenciala se lahko uporabijo tudi vzporedno s prekinitveno enoto enoprekinitvenih odklopnikov za izravnavo tranzientne povrnitve napetosti (TRV). Kondenzator za izravnavo potenciala je sestavni del odklopnika in se določi v skladu s specifikacijami odklopnika. Ta standard se uporablja za kondenzatorje za izravnavo potenciala, ki spadajo v eno ali v obe kategoriji za: – nameščanje na zračno izolirane odklopnike; – nameščanje na izolirane odklopnike (npr. potopljeni v SF6, olje itd.). Preskušanje za vsako zgoraj navedeno uporabo se v nekaterih primerih razlikuje. Namen tega standarda je: – določitev enotnih pravil glede lastnosti zmogljivosti, preskušanja in ocenjevanja; – določitev posebnih varnostnih pravil; – pomoč pri namestitvi in delovanju.
