Umjikelezo wesekethe lokuvuza komhlaba (i-ELCB)

Emkhakheni wokuphepha kukagesi, elinye lamadivayisi asemqoka asetshenzisiwe ngumhlaba wesekethe lomjikelezo wokuvuza komhlaba (i-ELCB). Le divayisi ebalulekile yezokuphepha yenzelwe ukuvikela imililo yokushaqeka nemililo ngokubheka ukugeleza kwamanje ngokugeleza kwesifunda nokuyicisha lapho kutholwa ama-voltages ayingozi lapho kutholwa ama-voltages ayingozi. Kule bhulogi, sizobhekisisa ukuthi yiliphi i-ELCB nokuthi lisigcina kanjani siphephile.

I-ELCB iyithuluzi lokuphepha elisetshenziselwa ukufaka imishini kagesi enomhlaba ophakeme wokuvimbela ukugwema ukushaqeka kukagesi. Isebenza ngokukhomba ama-voltages amancane adukayo avela kumathuluzi kagesi ekufakweni kwensimbi nokuphazamisa umjikelezo lapho kutholwa ama-voltages ayingozi. Inhloso yayo eyinhloko ukuvikela abantu nezilwane ukuthi zilimaze ukwethuka kukagesi.

Umgomo osebenzayo we-ELCB ulula kakhulu. Iqapha ukungalingani kwamanje phakathi kwabaqhubi besigaba kanye nomqhubi wezempi. Imvamisa, ukugeleza kwamanje kudlula kubaqhubi besigaba kanye nokugeleza kwamanje ngomqhubi we-izingalo kufanele kulingane. Kodwa-ke, uma kwenzeka iphutha, njengokuthi ngenxa ye-wiring noma ukufakwa okubangela ukuthi kube manje ukuvuza phansi, kuzovela ukungalingani. I-ELCB ithola lokhu kungalingani futhi kusika ngokushesha ukuhanjiswa kwamandla ukuvimbela noma yimuphi umonakalo.

Kunezinhlobo ezimbili zama-ELCBS: I-ELCS esebenza ngogesi kanye nama-ELCB asebenza njengamanje. I-ELCBS esebenza ngogesi isebenza ngokuqhathanisa imisinga yokufaka nokukhipha, ngenkathi ama-ElCBs asebenza njengamanje asebenzisa i-toroidal transformer ukuthola noma yikuphi ukungalingani ekuhambeni kwamanje okugeleza kwesigaba kanye nokuhamba ngokungathathi hlangothi. Zombili lezi zinhlobo zithola ngempumelelo futhi ziphendule emaphutheni kagesi ayingozi.

Kubalulekile ukuqaphela ukuthi ama-ELCBs ahluke kubaphuluki besifunda bendabuko, aklanyelwe ukuvikela ukugcwala ngokweqile kanye nemibuthano emifushane. Ngenkathi abaphukile bejikelezo kungenzeka bangahlali bahlale bebona amaphutha aphansi, ama-ELCBs aklanyelwe ukuphendula ama-voltages amancane adukayo futhi avikele ekushaqekeni kukagesi.

Ngamafuphi, i-Earth Dialoge Breaker Breaker (ELCB) iyithuluzi elibalulekile lokuphepha elidlala indima ebalulekile ekuvikeleni ukushaqeka kukagesi kanye nemililo kagesi. Ngokubheka ukugeleza kwamanje nokuphendula noma yikuphi ukungalingani noma iphutha, i-ELCB iyakwazi ukuvala amandla ngokushesha futhi ivikele noma yikuphi ukulimala okungaba khona kubantu nasezilwaneni. Njengoba siqhubeka nokubeka phambili ukuphepha ekhaya nasemsebenzini, kubalulekile ukuqonda ukubaluleka kwama-ELCB nokuthi asebenza kanjani.
