Isandulelo: Isiqalisi esithambile esine-voltage ephezulu, eyaziwa nangokuthi isiqalisi esithambile esiphakathi nendawo naphezulu (Isiqalisi esithambile esine-voltage ephezulu), siwuhlobo olusha lwesiqalisi senjini esihlakaniphile, esiqukethe iswishi ehlukanisayo, i-fuse. , isiguquli esilawulayo, imojula yokulawula, Imojula ye-thyristor, i-vacuum bypass contactor ene-voltage ephezulu, imojuli yokulawula, imojula ye-thyristor, i-high-voltage vacuum bypass contactor, ingxenye yokuvikela i-thyristor, ingxenye ye-optical fiber trigger, ukutholwa kwesignali kanye nengxenye yokuvikela, ukulawulwa kwesistimu nengxenye yokubonisa .I-high-voltage soft starter iyisisetshenziswa sokulawula isiphetho semoto esihlanganisa ukuqala, ukubonisa, ukuvikela, nokutholwa kwedatha, futhi singabona imisebenzi yokulawula eyinkimbinkimbi kakhulu.
I-high-voltage soft starter ilawula i-voltage yokufaka ngokulawula i-angle conduction ye-thyristor ukuze iguqule inani lamandla kagesi we-stator terminal ye-motor, okungukuthi, ingakwazi ukulawula i-torque yokuqala kanye nokuqala kwamandla enjini, ukuze isiqalo esithambile se-motor singabonakala Thatha ukulawula.Ngesikhathi esifanayo, ingakwazi ukusheshisa ngokushelelayo ngokusho kwemingcele yokuqala, ngaleyo ndlela inciphise umthelela kagesi kugridi, i-motor kanye nemishini.Lapho injini ifinyelela isivinini esikaliwe, i-bypass contactor ixhunywe ngokuzenzakalelayo.I-motor ingaqashwa ngemuva kokuqala, futhi kuhlinzekwa ukuvikelwa okuhlukahlukene kwamaphutha.
Idivayisi yokuqala ene-voltage ephezulu ingaqalisa umshini endaweni, noma isebenzise othintana naye omile wangaphandle ukuze iqalise ukude.Ngesikhathi esifanayo, i-PLC nokuxhumana (i-interface ye-485, i-Modbus) nayo ingasetshenziselwa ukulawula ukuqalisa.Uma uqalisa idivayisi ene-voltage ephezulu, ungakhetha izindlela ezimbili ezihlukene zesiqalo esithambile (isiqalo esithambile esijwayelekile, isiqalo esithambile esinomsebenzi wokukhahlela, isiqalo esithambile samanje, ukuqala kwerempu kagesi ekabili, njll.) noma ukuqala okuqondile ukuhlangabezana izidingo ezahlukene zesayithi lesicelo.
Indlela yokulawula ehlakaniphile ye-high-voltage soft starter ingasetha ngokunembile imingcele efana ne-torque yokuqala, ukuqala kwamanje, isikhathi sokuqala, nesikhathi sokuvala, futhi ingalawulwa ngokuxhumanisa ama-microcomputers nama-PLC.Uma kuqhathaniswa nesiqalisi esivamile (i-liquid high-voltage soft starter), inezinzuzo zosayizi omncane, ukuzwela okuphezulu, ukungathinteki, ukusetshenziswa kwamandla okuphansi, ukwethembeka okuphezulu, nokungakhathali (i-thyristor iyisisetshenziswa se-elekthronikhi esingaxhunywanga) Ukusebenza okuqhubekayo iminyaka eminingana ngaphandle kokuphumula kokulungiswa), ukufakwa kalula (kungafakwa ekusebenzeni ngemuva kokuxhuma ulayini wamandla kanye nolayini wemoto), isisindo esilula, imisebenzi ebanzi, ukusebenza okuzinzile, ukusebenza okunembile, njll.
I-soft-starter ene-voltage ephezulu ingakhuphula ngokushelela i-voltage ephumayo, igweme ukuqala komthelela, inikeze ukuvikeleka kwamasistimu okunikezwa kwamandla kagesi namamotho kanye nezinye izingxenye, futhi yelule impilo yesevisi yezinto zokusebenza zikagesi namasekhethi.
