Yintoni ii-breaker yesekethe evuzayo?
Isixhobo sokwaphula isekethe esivuzayo, isetyenziselwa ukuthintela ukutshayiswa kombane. Xa kuvuza, intsimi yemagnethi iveliswa yi-contact ephambili, i-coil yoqhagamshelwano ehlukanisayo, i-coil yoqhagamshelwano ehlukanisayo kunye neswitshi ephambili.
Isixhobo sokwaphula isekethe esivuzayoumsebenzi: xa isekethe imfutshane okanye ukugqithiswa kakhulu kunokuba yinto eyenzeka ngexesha elifanelekileyo, nqumla umbane.
Xa kukho isithinteli sokuvuza kwisekethe, ukuba kukho impazamo yokuvuza okanye ukugqithisa kakhulu, isithinteli sokuvuza asiyi kusebenza kwaye siya kuthumela isignali yesandi kunye nesibane. Akukho mfuneko yokuqhawula ngesandla.
Iinjongo eziphambili:
1. Ukukhusela ukhuseleko lomntu xa kuvuza izixhobo zombane zasekhaya okanye ezidityanisiweyo.
2. Iza kufakelwa kwiindawo zikawonke-wonke nakwiindawo ezinokutsha neziqhumayo (ezifana neeworkshops zemveliso, ii-warehouses, njl.njl.) apho abantu bahlala befuduka khona ukuze bathintele umlilo nezinye iingozi ezibangelwa kukuvuza kombane.
Ayikwazi ukwabelana ngomthombo wamandla nezinye izixhobo zombane.
1. Iswitshi yokukhusela ukuvuza ingawunqumla ngokukhawuleza umbane xa kukho i-short grounding circuit okanye i-grounding error kwinethiwekhi yamandla aphantsi, ngaloo ndlela iqinisekisa ukhuseleko lomntu kunye nokhuseleko kwizixhobo ezonakeleyo.
2. Kwimeko apho iswitshi yokukhusela ukuvuza kunye nezixhobo zombane zingasebenzi ngaxeshanye, ingxaki yokuvuza kwizixhobo zombane ingasuswa ngokukhetha ukuze ingabangela ukulahleka ngokupheleleyo kombane, ngaloo ndlela kuqinisekiswa ukhuseleko lomntu kunye nokuthintela ukwanda kweengozi zombane.
3. Kwigridi yamandla e-low-voltage enezintambo ezine enamanqanaba amathathu, xa kuvela impazamo yokumisa umhlaba enesigaba esinye, umbane unokucinywa ngokukhawuleza nangexesha elifanelekileyo ukuthintela ukwanda kwengozi.
4. Ukukhetha kweswitshi yokukhusela ukuvuza kulungile kakhulu ngenxa yemisebenzi yayo emibini yokukhululwa kombane ogqithisileyo (TN -C) kunye nokukhululwa komthwalo ogqithisileyo (TT-B).
5. Xa iindawo ezimbini zemoto ziphantsi komhlaba ngenxa yokutshayiswa ngumbane okanye ngesizathu esithile, umbane unokunqanyulwa ngokukhawuleza nangokuthembekileyo.
Musa ukusebenzisa umbane wesigaba esinye ekukhanyiseni.
Ukufakelwa kokhuseleko lokuvuza: 1. Ukufakelwa kokhuselo lokuvuza kufuneka kuhambelane nemigaqo efanelekileyo, indawo ekuyo kufuneka iqine kwaye ithembeke, kwaye kufuneka itshixwe njengoko kufuneka.
2. Uvavanyo lwesithinteli sokuvuza kufuneka lumiselwe ngumsebenzisi ngokwendlela esetyenzisiweyo ngayo, kodwa ngokubanzi akufuneki ludlule umbane osebenzayo okhuselekileyo (30mA).
3. Imodeli kunye neenkcukacha zesithinteli sokuvuza kufuneka zilungele umgca wokudibanisa.
4. Iitheminali zomkhuseli wokuvuza kunye neziphelo zombini zomgca womthwalo mazibe nonxibelelwano oluhle kwaye ziqine kwaye zithembeke.
5. Ukuba kufunyenwe ukuba isikhuseli sokuvuza sinomsindo ongaqhelekanga, ukunyuka kobushushu, ukuziva isandla ngendlela engaqhelekanga, njl.njl., kufuneka kufunyanwe ingcali yombane ngexesha elifanelekileyo ukuze ihlolwe kwaye ilungiswe.
6. Izikhuseli zokuvuza azinakusetyenziswa ixesha elide kwaye ngokubanzi azinakusetyenziswa ixesha elingaphezu kwesiqingatha sonyaka. Ukuba kuyimfuneko ukuqhubeka nokusebenzisa ezo zikhuseli, mazihlolwe ngokupheleleyo ngaphambi kokuba zisetyenziswe.
Ayinakutshintshwai-breaker yesekethe evuzayongesokhethi eqhelekileyo.
Ngenxa yokuba isokhethi eqhelekileyo ngokwayo igobolondo lesinyithi kunye nokufakwa kwe-insulation kweengcingo zangaphakathi azinakudlala indima yokukhusela, ngoko ke xa kuvela ukuvuza, umbane uya kungena emzimbeni ngesokhethi, nto leyo ekhokelela kwingozi yokutshona kombane.
Ukusetyenziswa kombane ngokukhuselekileyo kubaluleke kakhulu. Akukhathaleli nje ukhuseleko lwethu, kodwa nabantu abasingqongileyo. Ukuba awuyinaki indlela osetyenziswa ngayo umbane kwinkqubo yokhuseleko, ukungakhathali kuya kukhokelela ekutshatyalalisweni kombane. Ke ngoko, kubomi bemihla ngemihla kufuneka uphuhlise umkhwa olungileyo wombane okhuselekileyo.
Iswitshi yokukhusela ukuvuza inokwenza isilumkiso somlilo ngombane kwangethuba, ukujonga umlilo ngombane, ukulahla umlilo ngombane kunye neminye imisebenzi. Iswitshi yokukhusela ukuvuza ingafakwa kwigumbi lokusasaza kwaye ingafakwa kuyo yonke imfuneko yokukhusela indawo, inokunciphisa ngempumelelo amathuba eengozi ezibangelwa kukuvuza.
Xa usebenzisai-breaker yesekethe evuzayo, le micimbi ilandelayo iya kuqatshelwa:
1. Ngaphambi kokufaka i-circuit breaker evuzayo, kuyimfuneko ukujonga ngononophelo ukuba imbonakalo kunye nemigca yokudibanisa ye-circuit breaker evuzayo ilungile na kwaye ingaba iingcingo ezisetyenzisiweyo ziyahlangabezana nemigangatho. Ukulinganisa ukuba ixabiso langoku le-zero sequence ye-leaky circuit breaker lingaphakathi koluhlu oluqhelekileyo, akufuneki kubekho nto ingaqhelekanga ecacileyo ngaphambi kokuba i-leaky circuit breaker isebenze.
2. Xa ufaka i-leaking circuit breaker, kufuneka kuqwalaselwe ukusetyenziswa ngokuchanekileyo kwe-fuse enexabiso langoku elilinganisiweyo kwaye umbane kufuneka unqunyulwe ngaphambi kokuba ujonge i-leaking protector. I-leaking circuit breakers akufuneki zisetyenziswe ukuba i-external circuit ingena kwigumbi okanye ukuba kukho i-short-circuit error.
3. Xa ufaka i-circuit breaker evuzayo, i-circuit breaker mayibekwe kumhlaba othe tyaba noqinileyo kwaye isekelwe ngokuthembekileyo okanye ibekwe zero.
4. Emva kokufakelwa, i-leaking circuit breaker kufuneka ivavanywe rhoqo ngokunqumla umbane, kwaye ukuba ayinakudityaniswa kwimizuzu emi-2, umbane ungadityaniswa kwakhona.
