Ukuqonda Indima Yokutshintsha Umthwalo Kwiinkqubo Zokusasazwa Kombane Zanamhlanje

Iinkqubo zokusasazwa kombane zanamhlanje ziye zaba nzima ngakumbi njengoko amashishini, izakhiwo zorhwebo, kunye neziseko zophuhliso zifuna umbane ozinzileyo nongaphazanyiswayo. Ukuqinisekisa ukusebenza ngokukhuselekileyo kunye nokugcinwa ngokufanelekileyo, iinethiwekhi zombane zixhomekeke kuluhlu lwezixhobo zokutshintsha nokukhusela. Phakathi kwezi zinto, Ukutshintsha Umthwaloidlala indima ebalulekileyo ekulawuleni nasekuhlukaniseni iisekethe zombane phantsi kweemeko zomthwalo eziqhelekileyo.

Nangona ingaboneleli ngokhuseleko lwe-short-circuit njenge-circuit breaker, isetyenziswa kakhulu kwiinkqubo zokusasaza ukulawula ukusebenza, ukwahlukanisa ukugcinwa, kunye nokuthembeka kwenkqubo.Ukutshintsha Umthwaloimisebenzi kunye nalapho isetyenziswa khona inceda iinjineli kunye nabaphathi bezakhiwo ukuba bayile iinkqubo zamandla ezikhuselekileyo nezisebenza kakuhle.

1. Yintoni i-Load Switch kwaye isebenza njani kwiinkqubo zombane?

Iswitshi yomthwalo sisixhobo sokutshintsha umbane esenzelwe ukuqhagamshela okanye ukukhupha iisekethe zombane ngokukhuselekileyo ngelixa zithwele umsinga womthwalo oqhelekileyo. Ngokungafaniyo nee-isolators, ezimele zisebenze kuphela xa isekethe ingasebenzi kakuhle, iiswitshi zomthwalo ziyakwazi ukuphazamisa umsinga phantsi kweemeko zokusebenza eziqhelekileyo.

Esi sixhobo sidla ngokuba nezinto ezininzi ezibalulekileyo:

• Inkqubo yoQhagamshelwanoevula okanye evala isekethe

• Indlela yokusebenzanjengesiphatho sesandla okanye i-actuator enenjini

• Ulwakhiwo lokucima i-arcukulawula nokucinezela ii-arcs zombane ngexesha lokutshintsha

Xa iswitshi isebenza, oonxibelelwano bayahlukana okanye badibane, nto leyo evumela abaqhubi ukuba balawule ukuhamba kombane. Lo msebenzi wenzaUkutshintsha Umthwaloiluncedo kakhulu kwiiphaneli zokusasaza, iikhabhinethi zolawulo lwemizi-mveliso, kunye neenkqubo zokudlulisa umbane.
