Nagyfeszültségű kapcsoló- és vezérlőkészülékek. 103. rész: 1 kV-nál nagyobb és legfeljebb 52 kV névleges feszültségű, váltakozó áramú kapcsolók (IEC 62271-103:2021)

Angol cím

High-voltage switchgear and controlgear. Part 103: Alternating current switches for rated voltages above 1 kV up to and including 52 kV (IEC 62271-103:2021)

Alkalmazási terület

This part of IEC 62271 is applicable to three-phase, alternating current switches and switchdisconnectors for their switching function, having making and breaking current ratings, for indoor and outdoor installations, for rated voltages above 1 kV up to and including 52 kV and for rated frequencies from 16 2/3 Hz up to and including 60 Hz. This document is also applicable to single-pole switches used on three-phase systems. This document is also applicable to the operating devices of these switches and to their auxiliary equipment. For switch-disconnectors, refer also to IEC 62271-102 for their disconnecting function. Devices not covered by this document are: - devices that require a dependent manual operation; - earthing switches. Earthing switches forming an integral part of a switch are covered by IEC 62271-102; - switching devices attached as an element of a high-voltage fuse assembly or its mounting and operated by opening and closing the fuse assembly. General principles and provisions of this document can also be applicable to single pole switches intended for application in single-phase systems, the requirements for dielectric tests and making and breaking tests being in accordance with the requirements of the specific application. This document establishes requirements for general, limited and special purpose switches used in distribution systems. NOTE Except where special clarification is required, the term "switch" is used to refer to all kinds of switches and switch-disconnectors within the scope of this document.
