Ubufakazi bokuqhuma kwe-Shenhai
Izinga lokushisa eliphakeme lokushisisa lezinto ezingathinta ingxube yegesi-moya evuthayo ekuthuthukisweni kwemishini kagesi ephephile iyisici esibalulekile ekunqumeni ukuphepha okungaqhumeki kwamadivayisi kagesi.. Izingxenye eziphethe manje, ikakhulukazi izingxenye zamandla njengama-windings nezinto zokushisa, sebenza njengemithombo yokushisa ezintweni zikagesi.
Izinga lokushisa eliphezulu lokushisa akufanele lidlule izinga lokushisa elilinganiselwe lamadivayisi kagesi okuphepha akhuphukayo. Igama elithi ‘umkhawulo wokushisa’ ibhekisela ekushiseni okuphezulu okuvumelekile kwe izinto zikagesi ezingaqhumi, okungaphansi kwezinga lokushisa elinqunywa izinga lokushisa lemishini kanye nezinga lokushisa lapho izinto ezisetshenziswayo zithola ukuzinza kwe-thermal. Lo mkhawulo wezinga lokushisa yi- “umbundu” ukuze kuqinisekiswe ukusebenza kokuphepha kokuvikela ukuqhuma kwe ukwanda kokuphepha imikhiqizo kagesi. Uma izinga lokushisa eliphezulu lokushisisa lidlula izinga lokushisa elilinganiselwe, kungathungela okuhambelanayo eziqhumayo ingxube yegesi-yomoya noma kulimaze izakhiwo zikagesi nezinto ezisetshenziswayo. Ngokwesibonelo, ama-windings avaliwe, izinga lokushisa eliqhubekayo elingaphezu kwezinga lokushisa elizinzile linganciphisa ubude besikhathi saso sokuphila njalo ngo-8-10°C ukwanda.
Okwe-insulated windings, izinga lokushisa eliphezulu lokushisisa kwawo akufanele lidlule izinga elishiwo etafuleni.
Nciphisa Izinga Lokushisa Lama-Windings Angagqunyiwe

Okwamakhondatha aphethe amandla kagesi, ezingeni lokushisa eliphezulu lokushisa, amandla emishini yezinto ezibonakalayo akufanele ancishiswe, akufanele kube khona ukuguqulwa okungaphezu kwalokho ukucindezeleka okuvumelekile okukuvumelayo, futhi izinto eziseduze zokuvikela akufanele zonakaliswe. Ngokwesibonelo, esimweni sokuphepha okwandisiwe kwama-motor asynchronous ezigaba ezintathu, ukushisa kwe-rotor ngeke kulimaze ukufakwa kwe-stator windings.
Emklamweni we kwanda ukuphepha kwemishini kagesi, ukuvimbela izingxenye ezithile’ amazinga okushisa asuke eqe izinga lokushisa elilinganiselwe, abaklami kufanele bacabangele ukufaka izisetshenziswa ezifanele zokuvikela izinga lokushisa, ngaphezu kokusebenza kukagesi nokushisa kwezingxenye zikagesi, ukuvimbela ukushisa ngaphezu kwezinga lokushisa elilinganiselwe.
