Izimfanelo ezintathu eziyinhloko ze-AC contactor

Izixhumi ze-ACziyizingxenye ezibalulekile ezinhlelweni zikagesi, ikakhulukazi ekulawuleni ukuqala nokuma kwama-motor neminye imishini. Lawa ma-contactor anezici eziningana ezibalulekile ekusebenzeni kahle kwesekethe. Izimfanelo ezintathu ezinkulu ze-AC contactor zifaka phakathi i-AC contactor coil, oxhumana nabo abayinhloko kanye noxhumana nabo abasizayo. Isici ngasinye sidlala indima ebalulekile ekuqinisekiseni ukusebenza kahle kwesistimu kagesi.

Okokuqala, ikhoyili ye-AC contactor iyisakhi esiyisisekelo esihlukanisa ama-AC contactor kanyeAma-contactor e-DCAmakhoyili anelebula elithi A1 kanye nelithi A2 futhi ngokuyinhloko anesibopho sokukhiqiza insimu kazibuthe edingekayo ekusebenzeni kwe-contactor. Ngokuvamile, amakhoyili e-AC asetshenziswa ezinhlotsheni eziningi zokusebenza, ayakwazi ukuguqula amandla kagesi abe amandla omshini, okuvumela i-contactor ukuthi ivale futhi iqedele isekethe. Lesi sici senza i-AC contactor ikwazi ukulawula kahle ukugeleza kwamandla kagesi futhi yenze kube lula ukuqala nokuma kwemishini ehlukahlukene kagesi.

Okwesibili, ukuthintana okuyinhloko kwe-contactor ye-AC kuyingxenye ebalulekile yokuxhumanisa umugqa wamandla ongenayo wezigaba ezintathu kanye nomugqa wamandla ophumayo. Izintambo ezingenayo ziphawulwe ngokuthi yi-L1-L2-L3 kanti izintambo eziphumayo ziphawulwe ngokuthi yi-T1-T2-T3. Oxhumana nabo abakhulu bavame ukuvuleka futhi badlala indima ebalulekile ekulawuleni ukusebenza kwama-motor kanye neminye imishini. Oxhumana nabo abakhulu baqinisekisa ukusebenza kahle kohlelo lukagesi ngokubangela ukuthi isekethe ivuleke noma ivalwe, okuvumela ukulawulwa okunembile kokusebenza kwemishini.

Okokugcina, oxhumana nabo abasizayo be-contactor ye-AC banikeza ukusebenza okwengeziwe ngokuhlinzeka ngamaphuzu avame ukuvuleka (CHA) kanye namaphuzu avame ukuvaliwe (NC). Iphuzu elivame ukuvuleka livame ukusetshenziselwa ukulawula ukuzikhiya kwe-contactor kanye nokudlulisa isignali yokusebenza. Ngokuphambene nalokho, iphuzu elivame ukuvaliwe le-contactor ye-AC lisetshenziswa kakhulu ekuxhumeni kwesekethe kanye nokudlulisa isignali. Lesi sici sivumela ukuguquguquka okukhulu kumjikelezo wokulawula, okuqinisekisa ukusebenza kahle kanye nokuphepha.

Ngamafuphi, izici ezintathu ezinkulu ze-AC contactor—ikhoyili ye-AC contactor, ukuxhumana okuyinhloko, kanye nokuxhumana okusizayo—kufakazela indima ebalulekile edlalwa yilezi zingxenye ohlelweni lukagesi. Ama-AC contactor angaguqula amandla kagesi abe amandla omshini, alawule ugesi futhi anikeze imisebenzi eyengeziwe ngokusebenzisa ukuxhumana okusizayo. Ayingxenye ebalulekile yokuqinisekisa ukusebenza kahle nokuphephile kwamasekethe. Kungakhathaliseki ukuthi asetshenziswa ezinhlotsheni zezimboni noma zezentengiselwano, lezi zici zenza ama-AC contactor abe yinto ebalulekile ekuhlinzekeni ukulawula okuthembekile nokunembile kwemishini kagesi. Ngakho-ke, ukuqonda lezi zakhiwo ezibalulekile kubalulekile ekunqumeni ukufaneleka nokusebenza kahle kwama-AC contactor ezinhlelweni ezahlukene zikagesi.
