Uyini umfutho wesifunda lokuvuza komhlaba (i-ELCB) nokusebenza kwawo

Ama-Fricam Earth Earth Breakage BreakeAge Breakers ama-Voltage Detecting Detenting, manje aseshintshelwe ngamadivayisi azwayo wamanje (RCD / RCCB). Ngokuvamile, amadivaysi azwayo akhona manje abizwa nge-RCCB, kanye namadivayisi okuthola ama-voltage athola amadivaysi aqanjwe yi-Earth ukuvuvu (ELCB). Eminyakeni engamashumi amane edlule, kwalethwa ama-eclbs okuqala akhona futhi cishe eminyakeni engamashumi ayisithupha edlule kwenziwa i-Voltage ECLB yokuqala. Iminyaka eminingana, womabili ama-ELCS asebenza ngamandla asetshenzisiwe nawo wonke amanye abizwa ngokuthi ama-elecbs ngenxa yegama lawo elilula ukukhumbula. Kepha ukusetshenziswa kwalawa madivaysi amabili kunikeze ukukhula kokuxubha okukhulu emkhakheni kagesi.

Uyini umfutho wesekethe lomhlaba (i-ELCB)?

I-ECLB uhlobo olulodwa lwedivayisi yokuphepha esetshenziselwa ukufaka idivaysi kagesi enomhlaba ophakeme emhlabeni wokuvimbela ukugwema ukushaqeka. Lawa madivaysi akhomba ama-voltages amancane adukayo wedivayisi kagesi ekufakweni kwensimbi ekufakweni kwensimbi futhi angenele umjikelezo uma kukhonjwa i-voltage eyingozi. Inhloso esemqoka yomhlaba we-hlaba i-Breakage Breaker (ECLB) ukumisa ukulimala kwabantu nezilwane ngenxa yokushaqeka kukagesi.

I-ELCB uhlobo oluthile lokudluliswa kokuthambisa okunamandla angenayo ama-mains ahambisana noxhumana nabo obushintshayo ukuze umfukha wokujikeleza uvikele amandla esimweni esingaphephile. I-ELCB ibona amaphutha ama-currents womuntu noma wesilwane emhlabathini wire ku-uxhumano. Uma u-Ample Voltage ubonakala ngaphesheya komqondo we-ELCB's Sense Coil, uzocima amandla, futhi uhlale uze uhlele kabusha ngesandla. I-ELCB yokuzwa i-ELCB ayitholi amaphutha emfundweni kubantu noma ezilwaneni emhlabeni.

Umsebenzi we-ELCB

Umsebenzi oyinhloko we-Earth-Ukuvuza Breaker Breaker noma i-ELCB ukuvikela ukushaqeka ngenkathi ukufakwa kukagesi ngokusebenzisa i-High Earth Ukuvinjwa ngoba kuyithuluzi lokuphepha. Lo mlisa umjikelezo ukhomba ama-voltages amancane adukile ngaphezulu kwemishini kagesi enensimbi ebiyelwe ngensimbi futhi iphazamisa umjikelezo uma kukhonjwa i-voltage eyingozi. Inhloso enkulu yama-ELCBs ukugwema ukulimaza abantu kanye nezilwane ngenxa yokushaqeka kukagesi.

Ukusebenza kwe-ElcB
Umfutho wesifunda kagesi uhlobo oluthile lokudluliswa kokuthambisa futhi lunezindawo zokuhlinzekwa zezakhiwo ezixhumene kulo lonke oxhumana nabo ekushintsheni ukuze lo mphukeli wesifunda uzonqamula amandla lapho ukuvuvukala komhlaba. Ngokusebenzisa lokhu, iphutha lamanje lingatholwa empilweni liye ku-wire emhlabathini onogada abafanelekayo. Uma u-Ample Voltage uphuma emcabangweni wekhoyili we-breaker yesekethe, khona-ke izovala amandla futhi ihlale icishiwe kuze kube sethambekele emzimbeni. I-ELCB esetshenziselwa ukuzwela kwe-voltage ayitholi ama-Cuers amaphutha.

Ungakuxhuma Kanjani Ukuvuza Komsuka Wokuvuza Emjikelezayo

Umjikelezo womhlaba uguqulwa lapho kusetshenziswa i-ELCB; Ukuxhumeka kwenduku yoMhlaba kwamukelwa ngomhlaba wesekethe umjikelezo wokuvuza ngokuxhumanisa nama-terminals awo woMhlaba. Umuntu uya emkhakheni ofanele wesekethe umqhudeli (CPC), kanti omunye waya komunye emhlabathini noma olunye uhlobo lokuxhumana komhlaba. Ngakho-ke umhlaba wesekethe umhlaba uvumela ikhoyili ye-ELCB's Sense.

Izinzuzo zamandla kagesi asebenza i-ELCB

I-ELCBS ayinandaba kangako kwizimo zephutha futhi inemibala embalwa yokuhlangana.
Ngenkathi yamanje futhi i-voltage emgqeni womhlaba ngokuvamile amaphutha avela ku-wire bukhoma, lokhu akunjalo ngokuqhubekayo, ngakho-ke kunezimo lapho i-ELCB ingacasulwa khona.
Lapho ukufakwa kwensimbi kagesi kunontanga ezimbili emhlabeni, ukuhlasela okuphezulu okuphezulu okuphezulu kuzosusa i-voltage gradient emhlabeni, okunikeza i-ELCB Sense Coil nge-roil eyanele yokuyifaka ohambweni.
Uma ngabe iyiphi imibumba yenhlabathi ibanjwa kusuka ku-ELCB, ngeke isakufaka kaningi ingasabuzwa kahle.
Lawa ma-ELCBs anesidingo sokuxhuma kwesibili nethuba lokuthi noma yikuphi ukuxhumana okwengeziwe emhlabathini ohlelweni olusongelwayo kungangena umtshina.
