I-38kV 630A Uhlobo Lwe-Four-Position Oil Emmersed Load Switch

Ngowoyela we-transformer njengowoyela ohlanganisa nokuqothulwa kwe-arc okumaphakathi kanye nendlela yokusebenza yasentwasahlobo egcina amandla, le switch kawoyela enezimo ezimbili isebenza ku-transformer ehlanganisiwe enefrikhwensi engu-50Hz kanye ne-voltage elinganiselwe engu-25kV, iyakwazi ukuvula nokuvala umthamo wamanje. Ifakwe IVULIWE futhi IVALIWE izindawo ezimbili, ukujika kwewashi okuthi “VULIWE”, kuyilapho i-anticlockwise ithi “VALIWE”, i-engeli yokuzungezisa kufanele ilawulwe ngaphakathi kuka-90°. Ngaphezu kwalokho, ingafanelekela isistimu yokusabalalisa amandla okuphela noma isistimu yokusabalalisa amandla e-ring-network uma ifakwe ukulungiselelwa okwengeziwe.

Usayizi wokufaka wokubhuka wezindlu ze-transformer

Ukufakwa kweswishi yokulayisha

Ngaphambi kokufaka, sicela uhlole ukuthi ukunyakaza kokushintsha kuyavumelana nezimo futhi kunembile ngokucophelela, kuphela ngemva kokuqinisekiswa ukuthi kungaphansi kwesimo esihle, ukufakwa kungenziwa, ngaphezu kwalokho, ukushintsha komthwalo kufanele komiswe ngaphansi kwe-65±5ºCcondition ngo-24h.

5) Ngemuva kokufakwa nokuxhumeka, kuphakanyiswa ukuthi kwenziwe umsebenzi othi "vula" kanye "nokuvalwa" ukuze uhlole ukuthi iswishi inganyakaziswa kalula futhi uma inkomba yendawo ilungile, uma kukhona okungajwayelekile, sicela uhlole ukufakwa kweswishi kanye nokuxhumeka kwebha yebhasi ngokuya nge-athikili 2 no-4.
Amaphuzu okunakwa

1) Lokhu kushintsha kokulayisha kungasetshenziswa ukuvula noma ukuvala okwamanje okulinganiselwe kuphela, kuyilapho uhlelo lokusebenza lokuvala nokuvula ukwehluleka kwamanje. Uma i-current ilinganiselwe, kwenqatshelwe ukusebenzisa iswishi.

I-2) Ingalo ekhethekile yokusebenza evinjiwe kuphela engasetshenziswa ukusebenzisa lolu shintsho lomthwalo ukuze kuqinisekiswe ukuphepha komuntu siqu.
