Siyakwamukela kubhulogi yethu, lapho singena khona emhlabeni wamasistimu kagesi futhi sihlole izinto ezintsha zakamuva kulo mkhakha.Namuhla sizogxila engxenyeni ebalulekile edlala indima ebalulekile ekusetshenzisweni kukagesi okuningi -DC contactors.Ngokusebenza okuphumelelayo, okuthembekile, laba abathintwayo bangamathuluzi abalulekile ekuthuthukiseni ukusebenza nokuqinisekisa ukusebenza okungenamthungo kwezinhlelo zikagesi.

Oxhumana nabo abasebenzisa i-DCzingamadivayisi kagesi aklanyelwe ngokukhethekile ukuphatha imithwalo yamanje eqondile (DC).Ngokungafani nabathintana nabo be-AC, abathintwayo be-DC bahlinzeka ngesixazululo esibalulekile sezimboni nemikhakha ethembele kakhulu kumandla e-DC.Leziabathintwayozisetshenziswa kakhulu ezinhlelweni zikaloliwe, amandla avuselelekayo, izimoto zikagesi kanye neziteshi zokushaja amabhethri.

Enye yezinzuzo eziyinhloko zeOxhumana nabo abasebenzisa i-DCamandla abo okuphatha ama-voltage aphezulu nama-currents.Leli khono libavumela ukuthi balawule ngempumelelo futhi bavikele amasekhethi, ukunciphisa ubungozi bokulimala kwemishini noma ukwehluleka.Ukwengeza, ukuklama kwayo okuhlangene nokusebenza kahle kuyenza ifanelekele izinhlelo zokusebenza ezingenasikhala, njengezimoto zikagesi, lapho ukucatshangelwa kobukhulu nesisindo kubaluleke kakhulu.
Ngaphezu kokuqina,DC contactorsfuthi inikeza ukuthembeka okuphezulu ngenxa yokuguga okuncishisiwe.Ukungabikho kwe-arcing ngesikhathi sokushintsha imisebenzi kusiza ukunciphisa izidingo zokulungisa, kuqinisekisa ukusebenza okungaphazamiseki futhi kwandise impilo yonke yesistimu kagesi.Ukwengeza, lezi zokuxhumana zenzelwe ukumelana nezimo zemvelo ezinzima, zizenze zilungele ukusetshenziswa emazingeni okushisa aphakeme nezinye izindawo ezinokhahlo.

Mayelana nokusebenza kahle kwamandla,DC contactorsukuzuza imiphumela emangalisayo.Ngokulawula ngempumelelo ukuhamba kwamandla e-DC, laba abathintwayo basiza ukunciphisa ukulahleka kwamandla, ngaleyo ndlela bakhulise ukusebenza kahle futhi behlise ukusetshenziswa kwamandla.Le nzuzo ibaluleke kakhulu ezinhlelweni ezifana nokukhiqiza amandla avuselelekayo, lapho ukuqinisa ukusetshenziswa kwamandla kubalulekile ukuze kuzuzwe izinjongo zentuthuko esimeme.
Ngaphezu kwalokho, ukuvela kobuchwepheshe obuphambili kuye kwakhuthaza nokuthuthukiswa kwabahlakaniphileOxhumana nabo abasebenzisa i-DC.Laba abathintwayo bafakwe isistimu yokulawula ehlakaniphile ehlinzeka ngokuqapha okuthuthukisiwe nokuxilonga.Lokhu kuvumela ukulungiswa okusebenzayo kanye nokuvimbela ukwehluleka okungenzeka, ukunciphisa isikhathi sokuphumula kanye nokuthuthukisa ukusebenza kahle kokusebenza.

Sekukonke,DC contactorsyizici ezibalulekile ezidlala indima ebalulekile ekusetshenzisweni okuhlukahlukene ukuze kuqinisekiswe ukusebenza okuthembekile nokusebenza kahle kwezinhlelo zikagesi.Ngekhono labo lokuphatha ama-voltage aphezulu nama-currents, ukwethembeka ngisho nangaphansi kwezimo ezinzima, nezici zokonga amandla, laba abathintwayo bawumgogodla wezimboni eziningi.Njengoba ubuchwepheshe buqhubeka buthuthuka, singalindela ukuthuthuka okwengeziweDC contactorslokho kuzokwandisa ukusebenza kahle futhi kuvule indlela yekusasa elisimeme emkhakheni wezogesi kanye nezinhlelo zikagesi.
