Live working - Insulating aerial devices for mounting on a chassis

IEC 61057:2017 is applicable to insulating aerial devices for mounting on a chassis, to be used for live working on electrical installations at nominal voltages above 1 000V r.m.s. AC in the range 45 Hz to 65 Hz and 1 500V DC. This second edition cancels and replaces the first edition published in 1991 and IEC TS 61813:2000. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) general review of the requirements and test provisions; b) preparation of the elements of evaluation of defects, and general application of IEC 61318:2007; c) distinguishes between tests for hollow booms and those for foam filled booms; d) references ISO 16368 for particular mechanical tests; e) further information on vacuum protection and leakage current monitoring and a mandatory requirement that aerial devices for bare hand work be fitted with a permanently installed lower test electrode system; f) controls of high electrical resistance; g) reference to SAE for insulating hydraulic hoses; h) inclusion of IEC TS 61813 for care, maintenance and in-service testing of aerial devices with insulating booms.

Travaux sous tension - Dispositifs élévateurs isolants pour montage sur un châssis

L'IEC 61057:2017 s'applique aux dispositifs élévateurs isolants destinés à être montés sur un châssis, utilisés pour les travaux sous tension sur les installations électriques à des tensions nominales supérieures à 1 000 V en courant alternatif en valeur efficace dans la plage comprise entre 45 Hz et 65 Hz et à 1 500 V en courant continu. Cette deuxième édition annule et remplace la première édition, parue en 1991, ainsi que l’IEC TS 61813:2000. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: a) examen général des exigences et dispositions d'essai; b) préparation des éléments d'évaluation des défauts et application générale de l'IEC TS 61318:2007; c) distinction entre les essais pour bras creux et ceux pour bras remplis de mousse; d) référence à l'ISO 16368 pour les essais mécaniques particuliers; e) de plus amples informations sur la protection contre le vide et le contrôle du courant de fuite ainsi qu’une exigence obligatoire selon laquelle les dispositifs élévateurs destinés à des travaux au potentiel doivent être équipés de manière permanente d’un système d’électrode d’essai inférieure; f) contrôles de la résistance électrique élevée; g) référence à SAE pour les flexibles hydrauliques isolants; h) inclusion de l’IEC TS 61813 concernant les précautions à prendre, l’entretien et les essais en service des élévateurs à bras isolants.

Delo pod napetostjo - Izolacijske naprave za montažo na ohišja

Ta dokument se uporablja za izolacijske naprave za montažo na ohišja, ki so namenjene za delo pod napetostjo pri električnih napeljavah z nazivnimi napetostmi nad 1000 V RMS pri izmeničnem toku 45–65 Hz in 1500 V pri enosmernem toku.
Primarni namen teh naprav je namestitev pri delu osebja. Namestiti je mogoče tudi druge naprave (npr. ročice), ki so upravljavcu v pomoč pri izvajanju del.
Ta dokument vključuje tudi zahteve in preskuse za dele ohišij, ki vplivajo na lastnosti izolacijskih naprav, ki se uporabljajo za delo pod napetostjo.
Izolacijska naprava, nameščena na ohišju, postane sestavni del premične dvižne delovne ploščadi (MEWP). Dopolnilne zahteve glede ploščadi MEWP so zajete v standardu ISO 16368.
OPOMBA 1: V Evropi se kot referenca za dopolnilne zahteve namesto standarda ISO 16368 pogostokrat uporablja standard EN 280.
Proizvodi, zasnovani in izdelani v skladu s tem dokumentom, prispevajo k varnosti uporabnikov, kadar jih uporabljajo usposobljene osebe v skladu z varnimi metodami dela in navodili za uporabo.
OPOMBA 2: Morebitne zahteve, ki so v nasprotju z določili standarda ISO 16368 ali jih predvidoma dopolnjujejo, so razčlenjene v tem dokumentu.
Ta dokument ne zajema žerjavov z radialno roko (kopač).
