Omaka bomkhiqizo

I-PGS-630A iswishi yekhefu lokulayisha efakwe esigxotsheni isetshenziselwa ukwephula i-voltage elinganiselwe engu-12/24/40.5kV, ilinganiselwe i-630A yamanje, isistimu yokusabalalisa amandla angu-50/60Hz, ukuvala umthwalo wamanje kanye nomthwalo wamanje wesistimu yamandla, ingahlukanisa ngokuzenzakalelayo izingxenye zokulandelela ukusatshalaliswa kwamandla okuba khona amaphutha. Iswishi ifaniswe nesilawuli sikagesi esinobuchwepheshe bamuva nje. Iswishi ine-manual, motor, izindlela zokusebenza ezikude. Isilawuli se-elekthronikhi sizofakwa ngaphakathi kwebhokisi lensimbi engagqwali, ngakho-ke singasetshenziswa ezimweni zezulu ezihlukahlukene. Ngaphandle kwalokho, imodemu yocingo/engenantambo efakwe ngaphakathi kwebhokisi lokulawula ingafinyelela ukuqapha nokulawula kude. Kulula futhi kulungele ukufaka iswishi esigxotsheni, futhi lokho kungehlisa izindleko zokusebenzisa.
