Series capacitors for power systems - Part 3: Internal fuses

IEC 60143-3:2015 applies to internal fuses designed to isolate faulty capacitor elements, to allow operation of the remaining parts of that capacitor unit and the bank in which the capacitor unit is connected. Such fuses are not a substitute for a switching device such as a circuit-breaker, or for external protection of the capacitor bank, or any part thereof. The object of this part of IEC 60143 is: - to formulate requirements regarding performance and testing; - to provide a guide for coordination of fuse and bank protection. This second edition cancels and replaces the first edition published in 1998. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: The test procedure has been largely simplified. Keywords: faulty capacitor elements, fuse and bank protection

Reihenkondensatoren für Starkstromanlagen - Teil 3: Eingebaute Sicherungen

Condensateurs série destines à être installés sur des réseaux - Partie 3: Fusibles internes

L'IEC 60143-3:2015 s'applique aux fusibles internes destinés à isoler les éléments en défaut d'un condensateur, et permettre ainsi le maintien en service de la partie saine de l'unité de condensateur et de la batterie à laquelle cette unité est raccordée. Ils ne sont pas destinés à se substituer à un dispositif de coupure, par exemple un disjoncteur ou une protection externe de la batterie de condensateurs ou une partie de celle-ci. La présente partie de l'IEC 60143 a pour objet: - de formuler des exigences relatives aux performances et aux essais; - de fournir un guide pour la coordination de la protection par fusibles et de la protection de la batterie. Cette deuxième édition annule et remplace la première édition paru e en 1998. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: Les procédures d'essai ont été simplifiée. Mots clés: éléments en défaut d'un condensateur, protection par fusibles et de la protection de la batterie

Serijski kondenzatorji za elektroenergetske sisteme - 3. del: Notranje varovalke

Ta del standarda IEC 60143 velja za notranje varovalke, ki so namenjene izolaciji okvarjenih kondenzatorskih elementov, da bi se omogočilo delovanje preostalih delov take kondenzatorske enote in baterije, v katero je priključena kondenzatorska enota. Take varovalke niso nadomestek za stikalno napravo, kot je odklopnik, ali za zunanjo zaščito kondenzatorske baterije ali kateregakoli njenega dela.
Namen tega dela standarda IEC 60143 je:
– določitev zahtev glede zmogljivosti in preskušanja;
– zagotovitev navodil za usklajevanje varovalke in zaščite baterije.
OPOMBA Zunanje varovalke za zaporedne kondenzatorje so zajete v dodatku A standarda IEC 60143-1:2004: »Test requirements and application guide for external fuses and units to be externally fused«.
