Električni pogonski sistemi z nastavljivo hitrostjo - 5-1. del: Varnostne zahteve - Električne, toplotne in energijske (IEC 61800-5-1:2022 + COR1:2023)

Ta del standarda IEC 61800 določa zahteve za električne pogonske sisteme z nastavljivo hitrostjo (PDS) oziroma njihove elemente v zvezi z električno, toplotno, požarno, mehansko, energijsko nevarnostjo in drugimi pomembnimi nevarnostmi. Ne zajema pogonske opreme, razen zahtev za vmesnike. Uporablja se za električne pogonske sisteme z nastavljivo hitrostjo, ki vključujejo nadzor pretvorbe moči, osnovnega pogonskega modula/celovitega pogonskega modula in motor oziroma motorje.
Ne zajema osnovnega pogonskega modula/celovitega pogonskega modula za vleko in električna vozila.
Uporablja se za nizkonapetostne električne pogonske sisteme z nastavljivo hitrostjo, ki so namenjeni za pogon motorja ali motorjev iz osnovnega pogonskega modula/celovitega pogonskega modula, priključenega na medfazno izmenično napetost do vključno 1,0 kV (50 Hz ali 60 Hz) oziroma medfazno enosmerno napetost do vključno 1,5 kV.
Uporablja se tudi za visokonapetostne električne pogonske sisteme z nastavljivo hitrostjo, ki so namenjeni za pogon motorja ali motorjev iz osnovnega pogonskega modula/celovitega pogonskega modula, priključenega na medfazno izmenično napetost do vključno 35 kV (50 Hz ali 60 Hz) oziroma medfazno enosmerno napetost do vključno 52 kV.
OPOMBA 1: V času objave tega dokumenta je tehnična zgornja meja enosmerne napetosti za motorje na enosmerni tok znašala 2,25 kV.
OPOMBA 2: Vrednosti napetosti in frekvence nad temi mejami spadajo v področje uporabe standarda IEC 61800-1 in standarda IEC 61800-2.
OPOMBA 3: Za električne pogonske sisteme z nastavljivo hitrostjo, ki niso zajeti v področje uporabe tega standarda, je mogoče uporabiti veljavne zahteve drugih standardov, npr. IEC 62477-1 in IEC 62477-2.
Ta dokument se uporablja tudi za električne pogonske sisteme z nastavljivo hitrostjo, ki namenoma oddajajo ali sprejemajo radijske valove za namene radijske komunikacije.
Motorji za pogonsko opremo (glej sliko 1) so zajeti v standardu IEC 60034 (vsi deli).
OPOMBA 4: V nekaterih primerih lahko varnostne zahteve električnega pogonskega sistema z nastavljivo hitrostjo (na primer zaščita pred dostopom do nevarnih delov) zahtevajo uporabo posebnih sestavnih delov in/ali dodatnih ukrepov.
