(Main)High-voltage switchgear and controlgear - Part 302: Alternating current circuit-breakers with intentionally non-simultaneous pole operation
High-voltage switchgear and controlgear - Part 302: Alternating current circuit-breakers with intentionally non-simultaneous pole operation
IEC/TR 62271-302:2010 provides guidance on the design, construction, specification and testing of circuit-breakers with intentional non-simultaneous pole operation which are excluded from the scope of IEC 62271-100. In all other respects the scope of this technical report is identical to that of IEC 62271-100. This technical report provides supplementary information and guidance for this type of circuit-breaker and is intended to be used in conjunction with IEC 62271-100.
This publication is to be read in conjunction with IEC 62271-100:2008.
Appareillage à haute tension - Partie 302: Disjoncteurs à courant alternatif à fonctionnement intentionnellement non simultané des pôles
La CEI/TR 62271-302:2010 fournit des lignes directrices pour la conception, la fabrication, et les essais des disjoncteurs avec fonctionnement intentionnellement non simultané des pôles exclus du domaine d'application de la CEI 62271-100. Sur l'ensemble des autres aspects, le domaine d'application du présent rapport technique est identique à celui de la CEI 62271-100. Le présent rapport technique fournit des informations et lignes directrices supplémentaires pour ce type de disjoncteur et est destiné à être utilisé conjointement avec la CEI 62271-100.
Cette publication doit être lue conjointement avec la CEI 62271-100:2008.
