Uhlobo lokuqala: ku-conductor ozogoba ngesikhathi sokusebenza okujwayelekile, engeza umthwalo ongu-2kg kulayini wamandla futhi uwujikise izikhathi ezingu-20000 mpo (45 ° kuzo zombili izinhlangothi zomugqa).Umzimba wentambo yamandla kanye nepulaki kufanele zivulwe ngaphandle kokungajwayelekile (imvamisa: izikhathi ezingama-60 ngomzuzu ongu-1);
Uhlobo lwesibili: faka umthwalo we-2kg we-180 ° kulayini wamandla izikhathi ezingu-200 kumqhubi ogobile ngesikhathi sokugcinwa komsebenzisi (umqhubi ongeke agobe ngesikhathi sokusebenza okujwayelekile), futhi akukho okungavamile (imvamisa izikhathi ezingu-6 ku-1 iminithi).
Imingcele yezobuchwepheshe yolayini wamandla
izinga lobuchwepheshe
Ukukhethwa kwentambo yamandla kwenziwa ngokuvumelana nezimiso ezithile.Okubizwa ngokuthi "angeke kwehluleke ukwakha isahluko".Ukubukeka akwenziwa ngomoya omncane, kanjalo nentambo yamandla.Ikhwalithi, ukubukeka nezinye izidingo ezifanele nazo ziyasetshenziswa ngokuhambisana nezinhlinzeko zesitifiketi sentambo yamandla.Izimiso zokukhiqiza zezintambo zikagesi zimi kanje:
(1) Ngokwekhodi yobuchwepheshe yokuklama isistimu yamandla (sdj161-85) ekhishwe uMnyango
Ngokwezidingo zokukhethwa kwesigaba somqhubi wokudlulisa amandla, isigaba somqhubi welayini yokudluliswa kwamandla ka-DC siyakhethwa;
(2) Ikhodi yobuchwepheshe yokuklama izintambo zikagesi ezihamba phezulu eziyi-110 ~ 500kV (DL / t5092-1999);
(3) Iziqondiso zobuchwepheshe zolayini bamandla kagesi aphezulu e-DC (dl436-2005).
