SR EN 62271-104:2010

High-voltage switchgear and controlgear -- Part 104: Alternating current switches for rated voltages of 52 kV and above

IEC 62271-104:2009 applies to three-pole alternating current switches for rated voltages 52 kV and above, having making and breaking current ratings, for indoor and outdoor installations, and for rated frequencies up to and including 60 Hz. This standard is also applicable to the operating devices of these switches and to their auxiliary equipment. The main object of this standard is to establish requirements for switches used in transmission and distribution systems. General-purpose switches for this application are designed to comply with the following service applications: - carrying rated normal current continuously; - carrying short-circuit currents for a specified time; - switching of mainly active loads; - switching of no-load transformers; - switching of the charging current of unloaded cables, overhead lines or busbars; - switching of closed-loop circuits; - making short-circuit currents. A further object of this standard is to establish requirements for limited-purpose and special- purpose switches used in transmission and distribution systems. Limited-purpos
