Umphunga wesekethe (Elcb)

Kwicandelo lokhuseleko lombane, esinye sezixhobo eziphambili ezisetyenzisiweyo ngumhlaba wesekethe wesekethe (Elcb). Esi sixhobo sibalulekileyo sokhuseleko senzelwe ukuthintela ukothuka kunye nemibane ngokubeka iliso kwindlela yokuhamba ngoku ngesekethe kwaye icinyiwe phantsi xa kufunyanwa i-voltages eyingozi. Kwezi bhlog, siya kuhlolisisa ukuba yeyiphi i-ELCB kunye nendlela esisigcina ngayo.

I-ELCB sisixhobo sokhuseleko esisetyenziselwa ukufaka izixhobo zombane kunye ne-World Foldence ephezulu ukuthintela ukothuka kombane. Isebenza ngokuchonga i-Const kuchonga i-voltages encinci engafunekiyo kwizixhobo zombane kwindawo evaliweyo yentsimbi kwaye iphazamisa isekethe xa kufunyanwa i-voltages eyingozi. Eyona njongo iphambili kukunqanda abantu kunye nezilwanyana ukuba ziboshwe ngothuthu lombane.

Umgaqo wokuSebenza we-Elcb ulula kakhulu. Ibeka iliso ukungalingani kwangoku phakathi kwabaqhubi besigaba kunye nomqhubi ongathathi hlangothi. Ngokwesiqhelo, ukuqukuqela kwangoku kubaqhubi besigaba senqanaba kunye nokuhamba kwangoku ngokuhamba nangokungathathi hlangothi kufanele ukuba kulingane. Nangona kunjalo, ukuba impazamo yenzekile, ngenxa yokuba i-wiring ephosakeleyo okanye i-subsal enokubangela ukuba ivuza umhlaba, kuya kwenzeka. I-ELCB ifumana le ndlela yokungalingani kwaye ikhawuleza inciphise umbane ukuthintela nawuphi na umonakalo.

Zimbini iintlobo ze-ELCBs: I-ELCBS ye-Voltage-eSebenzayo kunye ne-ELCB esebenzayo. I-Elcbs-eSebenzayo-eSebenzayo isebenza ngokuthelekisa igalelo kunye ne-Elcbs esebenzayo, ngelixa i-ELCB esebenzayo isebenzisa i-toroidal yokuguqula ukufumana naluphi na ukungalingani ekuhambeni nasekuqalekeni kwangoku kunye nabaqhubi bexeshana. Zombini ezi ntlobo zichonge ngokufanelekileyo kwaye ziphendule kwiimpazamo zombane eziyingozi.

Kubalulekile ukuba uqaphele ukuba i-Elcbs yahlukile kwisekethe yesekethe, eyenzelwe ukukhusela ukugcwala komthwalo kunye nesekethe ezifutshane. Ngelixa abaphulaphuli besekethe banokubona iimpazamo ezikwinqanaba eliphantsi, i-ELCBs yenzelwe ngokukodwa ukuphendula kwi-voltages encinci yelahlekileyo kwaye ikhusele ngokuchasene nokothuswa kombane.

Isishwankathelo, umphula umthetho ovuza umhlaba (ELCB) sisixhobo esibalulekileyo sokhuseleko esidlala indima ephambili ekuthinteleni umlilo wombane kunye nemitya yombane. Ngokubeka iliso kuhambo lwangoku kwaye luphendula kulo naluphi na ukungalingani okanye impazamo, i-ElCB iyakwazi ukukhawulezisa amandla kwaye ithintele nakuphi na ukwenzakala ebantwini nakwizilwanyana. Njengoko siqhubeka nokubeka phambili ukhuseleko ekhaya nakwindawo yokusebenza, kubalulekile ukuba uqonde ukubaluleka kwe-ELCBs kunye nendlela abasebenza ngayo.
