Imodi yokuqala yesiqalisi
Imodi yokuqala ye-asynchronous motor enezigaba ezintathu
1, isiqalo esiqondile. Kodwa-ke, lapho i-motor ye-asynchronous enezigaba ezintathu iqala ngokuqondile, yamanje ingafinyelela izikhathi ezingu-6-7 zamanje ezilinganiselwe, ezinomthelela omkhulu kugridi yamandla, ikakhulukazi i-motor enamandla amakhulu.
2, ukuqala kwe-voltage encishisiwe. Isiqalo sembabala ikakhulukazi sihlanganisa isiqalo senyamazane eshisayo ye-autoroot kanye nesiqalo sembabala esingunxantathu wenkanyezi.
Ukuqala kwe-autobuck eshisayo kusho ukuthi i-motor voltage iyancishiswa futhi i-current current iyancipha ngesikhathi esifanayo lapho i-autotransformer iqalwa. Ngokuvamile yehliswa ibe cishe ku-55% -75% we-voltage elinganisiwe. Inzuzo ukuthi i-voltage yokuqala ingashintshwa kalula ngokushintsha inani lompompi we-autotransformer. Okubi kuyisidingo sokusebenzisa i-autotransformer, izindleko zikhulu.
Ukuqala kukanxantathu wenkanyezi kubhekisela endleleni yokuguqula i-voltage yokuqala ngokushintsha imodi yokuxhuma ye-motor, ukuze kuncishiswe ukuqala kwamanje, okungasetshenziswa kuphela kumodi evamile yokuxhumana yokuxhuma kukanxantathu we-motor. Lapho uqala, indlela yokudlulisela isetshenziswa ukwenza imodi ye-motor wiring ibe njengenkanyezi, ngalesi sikhathi, amandla kagesi esigaba ngasinye semoto ancishiswa abe ingxenye eyodwa kwezintathu yophawu lwempande yasekuqaleni, isivinini semoto sifinyelela cishe ku-80% isivinini esilinganisiwe, futhi i-relay yokulawula ishintsha imodi ye-motor wiring ibe ngunxantathu, futhi injini iqala ukusebenza ngokujwayelekile. Inzuzo yukuthi ingasindisa i-autotransformer, inciphise izindleko, futhi indlela ye-wiring ilula futhi ukwethembeka kukhulu. Okubi ukuthi isilinganiso se-voltage yokuqala asikwazi ukushintshwa, futhi injini ayikwazi ukusetshenziswa ekuxhumekeni kwenkanyezi.
3, imvamisa resistor ukuqala. Ukuqala kokumelana okuzwelayo kwe-frequency kusho ukuthi ukumelana ne-frequency sensitive sensitive kuxhunywe ochungechungeni lwesekethe eyinhloko lapho injini iqaliswa, ngaleyo ndlela kunciphisa imanje yokuqala. Ukumelana nemvamisa okuzwelayo kungashintsha isiqalo ngokushelela futhi kunomthelela omncane kugridi yamandla, ngakho kuyimodi yokuqala ekahle. Kodwa-ke, ama-resistors anamandla aphezulu azwela imvamisa asesimweni sama-inductors, ngakho-ke azokhiqiza i-electromagnetic eddy current enkulu esetshenziswayo, ezonciphisa isici samandla segridi.
