Uhlobo lokuqala: kumqhubi oza kugoba ngexesha lokusebenza okuqhelekileyo, yongeza umthwalo we-2kg kumgca wamandla kwaye ujiwule amaxesha angama-20000 ngokuthe nkqo (45 ° kumacala omabini omgca). Umzimba wentambo yombane kunye neplagi kufuneka ivulwe ngaphandle kokungaqhelekanga (i-frequency: amaxesha angama-60 kwi-1 ngomzuzu);
Uhlobo lwesibini: sebenzisa i-2kg yomthwalo we-180 ° kumgca wamandla ngamaxesha angama-200 kwi-conductor egobileyo ngexesha lokugcinwa komsebenzisi (i-conductor engayi kugoba ngexesha lomsebenzi oqhelekileyo), kwaye akukho nto ingaqhelekanga (i-frequency ngamaxesha angama-6 kwi-1 mzuzu).
Iiparamitha zezobugcisa zomgca wamandla
umgangatho wobugcisa
Ukukhethwa kwentambo yamandla kuqhutyelwa ngokwemigaqo ethile. Into ebizwa ngokuba yi " can't fail to form a chapter". Ukubonakalisa akwenziwa ngomoya obhityileyo, kwaye kunjalo nangentambo yamandla. Umgangatho, inkangeleko kunye nezinye iimfuno ezifanelekileyo nazo ziphunyezwa ngokuhambelana nezibonelelo zesatifikethi sentambo yamandla. Imigaqo yokwenziwa kwentambo yombane yile ilandelayo:
(1) Ngokwekhowudi yobugcisa yoyilo lwenkqubo yamandla (sdj161-85) ekhutshwe nguMphathiswa
Ngokweemfuno zokhetho lwecandelo lomqhubi wothumelo lwamandla, icandelo lomqhubi wentambo yothumelo lombane yeDC likhethiwe;
(2) Ikhowudi yobuchwephesha yoyilo lwe-110 ~ 500kV iintambo zothumelo oluphezulu (DL / t5092-1999);
(3) Izikhokelo zobuchwephesha zombane ophezulu wombane we-DC wothungelwano lwemigca ephezulu (dl436-2005).
