Kuyini ukushintsha komhlaba?

Iswishi yomhlaba, eyaziwa nangokuthi iswishi yokuhlukanisa umhlaba, yenzelwe ukuhlinzeka ngendlela yokunciphisa amandla nokuhlukanisa isekethe emthonjeni wayo. Inhloso eyinhloko yeswishi yomhlabathi ukusungula indlela eqondile eya emhlabathini, ngaleyo ndlela ikhiphe ngokuphephile noma yimuphi ugesi oweqile. Ngokumisa isekethe phansi, iswishi ivikela abantu nemishini ezingozini ezingaba khona njengokushaqeka kukagesi, amasekethe amafushane, nomlilo.

Amaswishi okufaka umhlaba ngokuvamile afakwa ku-mains supply noma i-switchboard. Ivumela izinhlelo zikagesi ukuthi zinqanyulwe futhi zibekwe phansi kalula lapho kudingeka umsebenzi wokulungisa, ukulungisa noma wokufaka. Ngokwenza lokhu, uqinisekisa ukuthi isekethe ayisebenzi kahle, okunciphisa ingozi yezingozi zikagesi phakathi nalezi zinqubo. Ekuphetheni, amaswishi okufaka umhlaba adlala indima ebalulekile ekuphepheni kukagesi ngokuhlinzeka ngezindlela eziphephile zokufaka amasekethe okufaka phansi.

Izinzuzo ze-earth switch yilezi ezilandelayo:

Ukuphepha okuphezulu: I-earth switch ingaxhumanisa ngempumelelo isekethe nentambo yomhlabathi. Uma kwenzeka ukuvuza noma ukwehluleka kwesekethe, ugesi ungaqondiswa phansi ngesikhathi ukuze kugwenywe ukulimala kokuphepha komuntu siqu.

Imishini yokuvikela: Iswishi yomhlaba ingahlinzeka ngesivikelo semishini kagesi. Uma i-voltage yemishini iphezulu kakhulu noma igcwele ngokweqile, iswishi yokumisa izonqamula ngokuzenzakalelayo isekethe ukuze igweme ukulimala kwemishini.

Nciphisa ukuphazamiseka kukagesi: I-earth switch inganciphisa ngempumelelo ukuphazamiseka kukagesi, njengokusebenzisa i-overvoltage, ukuphazamiseka kwamagagasi kagesi, njll., futhi inikeze indawo enhle kagesi.

Ukonga amandla nokuvikelwa kwemvelo: Ukusetshenziswa kwe-earth switch kungagwema ukuvuza kwamanje futhi kunciphise ukumoshwa kwamandla kagesi, ngaleyo ndlela kufezwe injongo yokonga amandla nokuvikela imvelo.

Ukulungiswa okulula: I-Earth switch ivame ukuba nezici zokuthembeka okuphezulu, impilo ende, ukusebenza okulula, njll., kanti ukulungiswa nokuphathwa kulula kakhulu.
