High-voltage switchgear and controlgear. Part 106: Alternating current contactors, contactor-based controllers and motor-starters (IEC 62271-106:2011)

Alkalmazási terület

This part of IEC 62271 is applicable to a.c. contactors and/or contactor-based controllers and motor-starters designed for indoor installation and operation at frequencies up to and including 60 Hz on systems having voltages above 1 000 V but not exceeding 24 000 V. It is applicable only to three-pole devices for use in three-phase systems, and single-pole devices for use in single-phase systems. Two-pole contactors and starters for use in singlephase systems are subject to agreement between manufacturer and user. Contactors and/or starters dealt with in this standard typically do not have adequate short-circuit interruption capability. In this context, this standard gives requirements for – motor starters associated with separate short-circuit protective devices; – controllers - contactors combined with short-circuit protective devices (SCPD). Contactors intended for closing and opening electric circuits and, if combined with suitable relays, for protecting these circuits against operating overloads are covered in this standard. This standard is also applicable to the operating devices of contactors and to their auxiliary equipment. Motor-starters intended to start and accelerate motors to normal speed, to ensure continuous operation of motors, to switch off the supply from the motor and to provide means for the protection of motors and associated circuits against operating overloads are dealt with. Motor-starter types included are – direct-on-line starters; – reversing starters; – two-direction starters; – reduced kVA (voltage) starters; · auto-transformer starters; · rheostatic starters; · reactor starters. This standard does not apply to – circuit-breaker-based motor-starters; – single-pole operation of multi-pole contactors or starters; – two-step auto-transformer starters designed for continuous operation in the starting position; – unbalanced rheostatic rotor starters, i.e. where the resistances do not have the same value in all phases; – equipment designed not only for starting, but also for adjustment of speed; – liquid starters and those of the "liquid-vapour" type; – semiconductor contactors and starters making use of semiconductor contactors in the main circuit; – rheostatic stator starters; – contactors or starters designed for special applications. This standard does not deal with components contained in contactors and contactor-based motor-starters, for which individual specifications exist. NOTE 1 Thermal electrical relays are covered by IEC 60255-8. NOTE 2 High-voltage current-limiting fuses are covered by IEC 60282-1 and IEC 60644. NOTE 3 Metal-enclosed switchgear and controlgear for rated voltages above 1 kV and up to and including 52 kV are covered by IEC 62271-200. NOTE 4 Disconnectors and earthing switches are covered by IEC 62271-102. NOTE 5 High-voltage switches above 1 kV and less than 52 kV are covered by IEC 62271-1031. The object of this standard is to state a) the characteristics of contactors and starters and associated equipment; b) the conditions with which contactors or starters shall comply with reference to: 1) their operation and behaviour, 2) their dielectric properties, 3) the degrees of protection provided by their enclosures, where applicable, 4) their construction, 5) for controllers, interactions between the various components, for example SCPD co-ordination; c) the tests intended for confirming that these conditions have been met, and the methods to be adopted for these tests; d) the information to be given with the equipment or in the manufacturer's literature.
