Yintoni umphunga wesekethe (i-ELCB) kunye nokusebenza kwayo

Abaphulaphuli besekethe abaseburhulumenteni abaziikhompyutha zizixhobo zokufumana i-Voltage Ngokubanzi, izixhobo ezikhoyo ezikhoyo zithi jikelele i-RCCB, kunye neevolthi ezifumana izixhobo ezibhalwe ngumhlaba ophule umhlaba kwi-Leakied (Elcb). Kwiminyaka engamashumi amane eyadlulayo, kwaziswa i-ECLBs yokuqala kwaye malunga neminyaka engamashumi amathandathu eyaziswayo i-ectage yokuqala ye-ectage. Kwiminyaka eliqela, zombini i-voltage kunye ne-ELCB esebenzayo yangoku yabizwa ngokuba yi-ELCBs ngenxa yegama labo elilula ukuze likhumbule. Kodwa ukusetyenziswa kwezi zixhobo zimbini kwanika ukukhula komxube obalulekileyo kushishino lombane.

Yintoni umphunga wesekethe umhlaba ovunayo (Elcb)?

I-ECLB ngolunye uhlobo lwesixhobo sokhuseleko esisetyenziselwa ukufaka isixhobo sombane esinegunya eliphezulu lokuthintela ukothuka. Ezi zixhobo zichonga voltages encinci yefowuni yefowuni yombane kwindawo ebiyelweyo kwaye ingenwe kwisiphatho sesekelo ukuba ichongiwe i-voltage eyingozi. Eyona njongo iphambili yomhlaba wesekethe (i-ECLB) kukuyeka ukonakaliswa kwabantu kunye nezilwanyana ngenxa yokothuswa kombane.

I-ELCB luhlobo oluthile lwe-latch edlulayo olwakha lona maxabiso angenayo angenayo onxulumene nonxibelelwano lwayo lokutshintsha ukuze umphuli wesekethe avelise amandla kwimo engakhuselekanga. Izaziso ze-Elcb uphosa i-upreys yomntu okanye isilwanyana emhlabeni Ukuba i-ivol yevolta enamandla ibonakala ingaphaya kwe-Elcb ye-Elcb ye-Elcb, iya kucima amandla, kwaye ihlale ihamba phantsi. I-Eltage i-Eltage i-Elcb ayifumani jelo uphoso lwempazamo kumntu okanye esilwanyana emhlabeni.

Umsebenzi we-ElCB

Umsebenzi ophambili wesekethe esekhompyutha emhlabeni okanye i-Elcb kukuthintela ukothuka ngelixa ufakelo lombane ngomhlaba ophakamileyo kuba sisixhobo sokhuseleko. Umbeki-wesekethe uchonga i-voltages encinci engagungqiyo ngaphezulu kwezixhobo zombane ezikwindawo ebiyelwe intsimbi kwaye iphazamisa isekethe ukuba kuchongiwe i-voltard yengozi. Eyona njongo iphambili ye-ELCBs kukuthintela ukwenzakala kubantu kunye nezilwanyana ngenxa yokothuswa kombane.

Ukusebenza kwe-ELCB
Iqhekeza lesekethe yombane lohlobo oluthile lokudlulisela phambili kwaye linezakhiwo zezakhiwo ezixhunyiweyo kuzo zonke iitshintshela zoqhawulo-mveliso ukuze umphunga wesekeke achongwe amandla. Ngokusebenzisa le nto, impazamo yangoku inokufunyanwa ebomini kwi-wire emhlabeni kwindawo efanelekileyo. Ukuba i-ampley voltage iphuma ngaphaya kwendlela ekhohlakeleyo yomphunga wesekethe, emva koko iya kuvala amandla kwaye ihlale iphinde isebenze ngokwasemzimbeni. I-ELCB esetyenziselwa i-voltage-imvakalelo ayiyifumani imijelo yempazamo.

Indlela yokuqhagamshela indlela yokuphula umhlaba

Isekethe yomhlaba ihlengahlengiswa xa isetyenziswa i-ELCB; Unxibelelwano lweDord lomhlaba lwamkelwe ngomhlaba otyhoboza umhlaba ophule ngokudibanisa ukuya kwi-terminals yayo yomhlaba. Omnye uye kwi-Work yoMkhuseli woMhlaba wasemhlabeni (CPC), kunye nolunye unxibelelwano lomhlaba okanye olunye uhlobo lonxibelelwano lomhlaba. Yiyo loo nto ipeyintiweyo yomhlaba ngesekethe ye-Elcb yeyakho.

Izibonelelo ze-Voltaged Elcb

I-ELCBs ayinantlonelo kwiimeko ezigwenxa kwaye ineehambo ezimbalwa zenkathazo.
Ngelixa i-voltage kumgca ophantsi komhlaba indleko ngokubanzi ngoku kwi-wire ephilayo, oku ayikokuqhubeka imeko, ke ngoko kukho iimeko apho i-ElCB inohambo lokucaphukisa.
Xa ufakelo lwesixhobo sombane lunabafowunelwa ababini emhlabeni, ukuhlasela okuphezulu kombane okukufutshane kuya kuncoma i-voltage emhlabeni, ukuhambisa i-Elcb Coil ngevoti ye-Elcb ngevolumitha yokufumana uhambo.
Ukuba enye yeengcingo zomhlaba ibanjiwe kwi-ELCB, ayisayi kuphinda ifake rhoqo ayisayi kutshatshelwa ngokuchanekileyo.
Ezi zinto ze-Elcbs ziyimfuneko yonxibelelwano lwesibini kunye nethuba lokuqhagamshelwa kolwalamano olungaphezulu komhlaba kwisiseko esisoyikisiweyo sinokusebenzisa umcuphi.
