zingaki izikhathi ezingakwazi ukuqala ama-motor high-voltage

Ngokuthuthukiswa kwemishini emikhulu nemishini, amandla emoto afanayo nawo aya ngokuya eba mkhulu, njengesitshalo se-hydrogenation, i-hydrogen compressor entsha esekela amandla e-synchronous motor akalwe angu-10,000 KW.izidingo ezijwayelekile zamamotho ane-voltage ephezulu ukuze akwazi ukuhlangabezana nazo: izikhathi ezi-3 isiqalo esibandayo, isiqalo esishisayo izikhathi ezi-2.

Amanye ama-motor-voltage aphezulu (i-10KV noma ngaphezulu) ezinqubweni zokusebenza, ihora lenombolo yokuqalisa akufanele lidlule izikhathi ezi-3, ezihlukaniswe isiqalo esibandayo kanye nesiqalo esishisayo.Ukuqala okubandayo okungukuthi, ngaphambi kokuqala kwesikhawu kusukela ngesikhathi sokugcina sokugcina, uma kukhulu kunesikhathi esishiwo ivelu lomkhiqizi wesiqalo esibandayo, futhi okuphambene nalokho, okungukuthi, ukuqala okushisayo.(Kukhona futhi abakhiqizi badinga izinga lokushisa lokuvunguza kwe-motor kanye nomehluko wokushisa ozungezile) Lokhu ikakhulukazi ukuvikela injini, ngoba i-current-up current iphezulu kakhulu, i-winging izoshisa, uma ukuqaliswa kuphumelela, ukupholisa injini. izobe ijikeleza nge-rotor ku-motor ukupholisa okuphoqelekile (i-air-cooled ephoqelekile), uma ukuqala kokugcina kokushisa okukhiqizwa amandla aphezulu akukwazi ukusabalalisa ngesikhathi esifanele, kulandelwa ukuqala, bese izinga lokushisa eliphezulu lizoba izinga lokushisa lemoto eliqhubekayo Phakamisa ukukhuphuka kwezinga lokushisa kuholela ekwehleni kwekhwalithi ye-motor insulation, futhi ekugcineni kulimaze ukuqalisa kwe-motor winding motor, ukuqalisa kwamanje kukhulu, ukushisa okwengeziwe, inani lokuqalisa elivumelekile ukushisa kwenza ayithinti impilo yokufakwa kwezimoto kanye nempilo yesevisi ngomgomo wokunquma.

Ama-motor amaningi angaqalwa izikhathi eziningi, ukuzinza kwawo kokufakwa kuhlala ngaphakathi kwenani elivumelekile, kepha kunenombolo encane yamandla amakhulu noma ama-motor anenjongo ekhethekile, ngenani lokuqalwa kwezidingo zesikhathi seyunithi, lawa ma-motor azokhonjwa. ngaphandle kokucaciswa komkhiqizo wayo.

Ngaphansi kwezimo ezijwayelekile, i-squirrel-cage rotor motor, evunyelwe esimweni esibandayo, iqala izikhathi ezingu-2 - 3, isikhathi ngasinye isikhathi ngeke sibe ngaphansi kwemizuzu emi-5;kuvunyelwe esimweni esishisayo qala kanye.Kuphela uma ubhekene nezingozi, futhi isikhathi sokuqala singekho ngaphezu kwemizuzwana engu-2 - 3 yeyunithi ingaqalwa ngaphezu kwesisodwa.

Ngokuvamile, isikhawu sesimo esibandayo semoto esingaphezu kuka-10KV sesigamu sehora, isikhathi sokuphumula sesimo esishisayo amahora angu-2 – 4 noma ngaphezulu.Izidingo ezithile zihlobene nosayizi wemoto kanye nezidingo zomkhiqizi wemoto.
