Ikhabhinethi yesimo sokuqalisa esithambile kagesi ephezulu ifaneleka kakhulu (3~10kV) ikheji lezingwejeje ukuqala kwenjini nokulawula kokumisa nokuvikela. Izingxenye zekhwalithi ephezulu ze-anti-parallel thyristor kanye nemishini yokulawula i-elekthronikhi ixhunywe phakathi kwe-stator winding ye-high voltage motor kanye nokunikezwa kwamandla. Lapho i-motor iqala, ngokomthetho othile (njengokuthambekela okungaguquki kwamanje noma i-voltage) lawula inhlanzi yokuqhuba yeshubhu le-interproduct, futhi ngokuqhubekayo uguqule okokufaka kweqembu lokugcina le-stator ukusuka ekucindezelweni kuya ekucindezelweni okugcwele, ngemuva kokuqala. sekuqediwe, isixhumi se-bypass siyadwetshwa. Inomsebenzi wokuvikela amaphutha njengokusika ngokweqile, ukuqalisa kwesigaba esifushane, i-peak overcurrent, njll. Ukuyisebenzisa kungagwema ngempumelelo umthelela oyingozi obangelwa ukuqalisa kwenjini ngokweqile kugridi yamandla, futhi ngokuvamile kungasebenzisa injini yamandla aphezulu. ngaphansi komthamo wegridi yamandla alinganiselwe futhi andise impilo yayo yesevisi. Ngaphezu kwalokho, i-High voltage soft start start state cabinet nayo inomsebenzi “we-soft stop”, lapho isitobhile, i-motor stator winding voltage izoncishiswa kahle, ngaleyo ndlela kugwemeke ukumiswa okungazelelwe kwemishini, ewusizo empompini (ingagwema). umphumela wesando samanzi) noma ibhande lokuhambisa.
1. Usayizi omncane kanye nemisebenzi egcwele
Ikhabhinethi yamapulangwe ihlanganisa ikhabethe le-high-voltage solid-state-soft-start, i-high-voltage switch, kanye nekhabhinethi ye-bypass ibe yikhabhinethi ehlanganisiwe. Incane ngosayizi. Uma kuqhathaniswa nekhabhinethi ehlukile ye-high-voltage switch kanye nekhabhinethi yokufundisa,
Indawo yekhabhinethi yokuqala iyancipha ngesigamu, futhi inemisebenzi yokuqala ethambile, isitobhi esithambile, i-switch cabinet kanye ne-bypass cabinet.
2. Umsinga wokuqalisa uncane futhi umphumela wokonga ubalulekile
Ikhabhinethi edidiyelwe yeswishi ephakathi nendawo nephezulu eqinile-isiqalo esithambile ilungisa i-voltage ngokushintsha i-engeli yokuqhuba ye-thyristor, ngaphandle kokulahlekelwa amandla kanye nokuqala kwamanje.
Incane, izikhathi ezingu-2.5~3.5 kunamanje olinganiselwe.
3. Ikhono eliqinile lokulwa nokuphazamiseka, elivumelana nezimo ezihlukahlukene zokusetshenziswa
Le khabhinethi yakhelwe ngomjikelezo okhethekile wokumunca amandla wokumelana, onokusebenza okuqinile kokulwa nokuphazamiseka. Ukusebenza komkhiqizo kuzinzile, akuthintwa izinga lokushisa le-ambient kanye nendawo, futhi kungaqalwa njalo.
4. Imisebenzi yokuvikela ephelele kanye nokuphepha okuphezulu
Inemisebenzi yokuvikela amaphutha njengokulayisha ngokweqile, ukulahleka kwesigaba, kanye nokuqala ukudlulela kwenani eliphakeme. Amapharamitha okuqala angokuzithandela, ayalungiseka futhi ayalawuleka.
5. Akukho sondlo, ukonga
Idizayini engenakulungiswa inciphisa izintambo zezintambo zamakhabhinethi okushintsha amandla kagesi aphezulu kanye namakhabethe aqala kancane. Asikho esinye isondlo esidingekayo ngemva kokusetshenziswa, esingalondoloza imali eningi ezindlekweni zokunakekela.
