High-voltage switchgear and controlgear - Part 102: Alternating current disconnectors and earthing switches (IEC 62271-102:2018)
This part of IEC 62271 applies to alternating current disconnectors and earthing switches,
designed for indoor and outdoor installations for nominal voltages above 1 000 V and for
service frequencies up to and including 60 Hz.
It also applies to the operating devices of these disconnectors and earthing switches and their
auxiliary equipment.
Additional requirements for disconnectors and earthing switches in enclosed switchgear and
controlgear are given in IEC 62271-200, IEC 62271-201 and IEC 62271-203.
NOTE Disconnectors in which the fuse forms an integral part are not covered by this standard.
This document is also applicable to switching devices having disconnecting and/or earthing
functionalities apart from other functions, such as high-speed earthing switch, circuit-breaker
and switch-disconnector.

Visokonapetostne stikalne in krmilne naprave - 102. del: Ločilna stikala za izmenični tok in ozemljitvena stikala (IEC 62271-102:2018)
Ta del standarda IEC 62271 se uporablja za ločilna stikala za izmenični tok in ozemljitvena stikala za notranje in zunanje inštalacije za nazivne napetosti nad 1000 V in storitvene frekvence do in vključno s 60 Hz.
Prav tako se uporablja za krmilne naprave teh ločilnih in ozemljitvenih stikal ter njihovo dodatno opremo.
Dodatne zahteve za ločilna in ozemljitvena stikala v zaprtih stikalnih in krmilnih napravah so podane v standardih IEC 62271-200, IEC 62271-201 in IEC 62271-203.
OPOMBA Ločilna stikala, pri katerih je varovalka bistveni del, ne spadajo na področje uporabe tega standarda. Ta dokument se uporablja tudi za stikalne naprave s funkcijo prekinjanja in/ali ozemljitve, poleg drugih funkcij, kot so hitra ozemljitvena stikala, odklopniki in stikala/ločilna stikala.
