Ulwakhiwo
● Le mveliso yenziwe ngesixhobo sokusasaza amandla ombane aphezulu, isiguquli, kunye nesixhobo sokuhambisa amandla ombane ophantsi. Yahlulahlulwe yangamacandelo amathathu asebenzayo, angala, igumbi lombane ophezulu, igumbi lokutshintsha kunye negumbi lombane ophantsi. Amagumbi ombane aphezulu naphantsi anayo yonke imisebenzi, kwaye icala lamandla ombane aphezulu yinkqubo yonikezelo lwamandla ephambili. Inokucwangciswa ngokweendlela ezininzi zobonelelo lwamandla ezifana nombane womnatha weringi, unikezelo lwamandla ombane, unikezelo lwamandla amabini, njl. I-S9, i-SC kunye nolunye uchungechunge lwe-oyile yelahleko ephantsi i-transformers okanye i-transformers eyomileyo ingakhethwa kwigumbi lokuguqula; Igumbi lombane eliphantsi linokwamkela ipaneli okanye isakhiwo esixhonywe kwikhabhinethi ukwenza iskimu sobonelelo lwamandla olufunwa ngabasebenzisi. Inemisebenzi yokusasazwa kombane, ukuhanjiswa kokukhanya, imbuyekezo yamandla asebenzayo, umlinganiselo wamandla ombane kunye nomlinganiselo wobungakanani bombane ukuhlangabezana neemfuno ezahlukeneyo zabasebenzisi. Kukulungele ukuba abasebenzisi balawule unikezelo lwamandla kunye nokuphucula umgangatho wonikezelo lwamandla.
● Ulwakhiwo lwegumbi lombane ophezulu luxinene kwaye lunengqiqo, kwaye linomsebenzi we-interlock we-anti misoperation. Xa kufunwa ngabasebenzisi, i-transformer inokuxhotyiswa ngeereyili, ezinokufumaneka ngokulula kwiingcango kumacala omabini kwigumbi lokuguqula. Igumbi ngalinye lixhotyiswe ngesixhobo sokukhanyisa esizenzekelayo. Ukongeza, onke amacandelo kumagumbi aphezulu kunye naphantsi kwamandla ombane anentsebenzo ethembekileyo kunye nokusebenza kakuhle, okwenza imveliso iqhube ngokukhuselekileyo nangokuthembeka kwaye igcinwe ngokufanelekileyo.
● Ukungenisa umoya wendalo kunye nokunyanzeliswa komoya kuyamkelwa. Kukho iziteshi zokungenisa umoya kwigumbi lokuguqula, amagumbi aphezulu kunye naphantsi kwamandla ombane, kwaye i-fan yokukhupha ixhotywe ngesixhobo sokulawula ubushushu, esinokuqala ngokuzenzekelayo kwaye sivale ngokuhambelana nokushisa okumiselweyo ukuqinisekisa ukusebenza okuqhelekileyo kwe-transformer.
● Ukwakhiwa kwebhokisi kunokuthintela ukungena kwamanzi emvula kunye nokungcola. Izinto eziphathekayo zenziwe ngepleyiti yensimbi yombala kwaye inomsebenzi we-anti-corrosion kunye nokushisa ukushisa. Ngeemeko zokusetyenziswa kwangaphandle kwexesha elide ukuqinisekisa ukuchasana nokubola, ukungangeni kwamanzi, ukusebenza kothuli, ubomi benkonzo ende, kunye nenkangeleko entle.
