Yintoni iswitshi yoMhlaba?

Iswitshi yomhlaba, eyaziwa ngokuba yiswitshi yokwahlukanisa umhlaba, yenzelwe ukubonelela ngendlela yokunciphisa amandla nokwahlula isekethe kumthombo wayo. Injongo ephambili yeswitshi yomhlaba kukumisela indlela ethe ngqo emhlabeni, ngaloo ndlela ikhuphe ngokukhuselekileyo nawuphi na umbane ogqithisileyo. Ngokumisa isekethe phantsi, iswitshi ikhusela abantu nezixhobo kwiingozi ezinokubakho ezifana nokutshayiswa ngumbane, ii-short circuits, kunye nomlilo.

Iiswitshi zokufaka umhlaba zihlala zifakelwa kumbane ophambili okanye kwibhodi yokutshintsha. Oku kuvumela iinkqubo zombane ukuba ziqhagamshelwe kwaye zibekwe phantsi ngokulula xa kufuneka ukulungiswa, ukulungiswa okanye ukufakwa. Ngokwenza oku, uqinisekisa ukuba isekethe ayisebenzi kakuhle, nto leyo enciphisa umngcipheko weengozi zombane ngexesha lezi nkqubo. Ukuqukumbela, iiswitshi zokufaka umhlaba zidlala indima ebalulekileyo kukhuseleko lombane ngokubonelela ngeendlela ezikhuselekileyo zokufaka iisekethe phantsi.

Iingenelo ze-earth switch zezi zilandelayo:

Ukhuseleko oluphezulu: Iswitshi yomhlaba ingaqhagamshela ngokufanelekileyo isekethe kwintambo yomhlaba. Xa kuvuza okanye kungasebenzi kakuhle kwisekethe, umbane ungaqondiswa emhlabeni ngexesha elifanelekileyo ukuze kuthintelwe ubungozi kukhuseleko lomntu.

Izixhobo zokukhusela: Iswitshi yomhlaba inokubonelela ngokhuseleko kwizixhobo zombane. Xa i-voltage yezixhobo iphezulu kakhulu okanye igcwele kakhulu, iswitshi yokumisa umhlaba iya kuyinqumla ngokuzenzekelayo isekethe ukuze ithintele umonakalo kwizixhobo.

Nciphisa ukuphazamiseka kombane: Iswitshi yomhlaba inganciphisa ngempumelelo ukuphazamiseka kombane, okufana nokugqithisa kwamandla ombane, ukuphazamiseka kwamaza ombane, njl.njl., kwaye ibonelele ngendawo efanelekileyo yombane.

Ukonga amandla kunye nokukhuselwa kokusingqongileyo: Ukusetyenziswa kwe-earth switch kunokuthintela ukuvuza kwamandla ombane kwaye kunciphise inkcitho yamandla ombane, ngaloo ndlela kufezekiswa injongo yokonga amandla kunye nokukhusela okusingqongileyo.

Ukugcinwa lula: Iswitshi yoMhlaba idla ngokuba neempawu zokuthembeka okuphezulu, ubomi obude, ukusebenza lula, njl.njl., kwaye ukugcinwa nolawulo kulula kakhulu.
