Imodi yokuqala yesiqalo
Imodi yokuqala yemoto engasebenzi kahle enezigaba ezintathu
1, ukuqala okuqondile. Kodwa-ke, lapho injini yesigaba esithathu i-asynchronous iqala ngqo, ugesi ungafinyelela izikhathi ezingu-6-7 kunogesi olinganisiwe, okunomthelela omkhulu kugridi yamandla, ikakhulukazi injini enamandla amakhulu.
2, ukuqala kwe-voltage encishisiwe. Ukuqala kwe-buck kuhlanganisa kakhulu ukuqala kwe-buck okushisayo kwe-autoroot kanye nokuqala kwe-buck okunenkanyezi.
Ukuqala kwe-autobuck eshisayo kusho ukuthi i-voltage yemoto incishisiwe kanti i-starting current incishisiwe ngesikhathi esifanayo lapho i-autotransformer iqalwa. Ngokuvamile incishiswa ibe cishe ngu-55%-75% we-voltage elinganisiwe. Inzuzo ukuthi i-starting voltage ingashintshwa kalula ngokushintsha inani lama-tap e-autotransformer. Inkinga isidingo sokusebenzisa i-autotransformer, izindleko zinkulu.
Ukuqala phansi kwe-star triangle kubhekisela endleleni yokushintsha i-start voltage ngokushintsha imodi yokuxhuma yemoto, ukuze kuncishiswe amandla okuqala, angasetshenziswa kuphela kwimodi yokuxhuma evamile yokuxhuma kwe-triangle yemoto. Uma uqala, indlela yokudlulisela isetshenziswa ukwenza imodi yokuxhuma yemoto ibe yinkanyezi, ngalesi sikhathi, i-voltage yesigaba ngasinye semoto yehliswa ibe yingxenye yesithathu yesibonakaliso sokuqala sempande, isivinini semoto sifinyelela cishe ku-80% wejubane elilinganisiwe, futhi i-control relay ishintsha imodi yokuxhuma yemoto ibe yinxantathu, futhi imoto iqala ukusebenza ngokujwayelekile. Inzuzo ukuthi ingasindisa i-autotransformer, inciphise izindleko, futhi indlela yokuxhuma ilula futhi ukuthembeka kukhulu. Okubi ukuthi isilinganiso se-start voltage asikwazi ukushintshwa, futhi imoto ayikwazi ukusetshenziswa ekuxhumekeni kwenkanyezi.
3, ukuqala kokumelana nemvamisa. Ukuqala kokumelana nemvamisa kusho ukuthi ukumelana nemvamisa kuxhunywe ngokulandelana kusekethe eyinhloko lapho injini iqalwa, ngaleyo ndlela kuncishiswe ugesi oqalayo. Umshini wokumelana nemvamisa ungashintsha ugesi oqalayo kahle futhi ube nomthelela omncane kugridi yamandla, ngakho-ke kuyindlela efanele yokuqala. Kodwa-ke, ama-resistor anamandla aphezulu azwela imvamisa asesimweni sama-inductor, ngakho azokhiqiza ugesi omkhulu we-electromagnetic eddy osetshenziswayo, ozonciphisa amandla egridi.
I-Zhuo Meng Shanghai Auto Co., Ltd. izibophezele ekuthengiseni izingxenye zezimoto ze-MG&MAUXS futhi wamukelekile ukuzithenga.
