Ukukhuselwa kokuvuza ukuqinisekisa ukhuseleko.

Yintoni naukuvuza isaphuli sesekethe?

Ukuvuza kwesekethe i-breaker, isetyenziselwa ukuthintela ukutshatyalaliswa kombane.Xa ukuvuza kwenzeka, intsimi yamagnetic iveliswa ngumfowunelwa oyintloko, i-coil yokudibanisa eyahlulayo, i-coil yokudibanisa eyahlula kunye nokutshintsha okuphambili.

Ukuvuza kwesekethe i-breakerumsebenzi: xa isiphaluka esifutshane okanye i-overload inokuba yintshukumo ngexesha elifanelekileyo, kunqunyulwa ukunikezelwa kwamandla.

Xa kukho umkhuseli wokuvuza kwisekethe, ukuba kukho ukuvuza okanye impazamo yokugcwala kakhulu, umkhuseli wokuvuza akayi kusebenza kwaye uya kuthumela isandi kunye nokukhanya kwe-alam yokukhanya.Akukho luqhawulo lwezandla olufunekayo.

Iinjongo eziphambili:

1. Ukukhusela ukhuseleko lomntu xa kukho ukuvuza kwendlu okanye izixhobo zombane ezihlangeneyo.

2. Iya kufakwa kwiindawo zikawonke-wonke kunye neendawo ezinokutsha kunye neziqhushumbisi (ezifana neeworkshops zokuvelisa, iindawo zokugcina iimpahla, njl.njl.) apho abantu bahlala beshukuma ukunqanda umlilo kunye nezinye iingozi ezibangelwa kukuvuza kombane.

Awunakukwazi ukwabelana ngomthombo wamandla nezinye izixhobo zombane.

1. Umtshini wokukhusela ukuvuza unokuphelisa ngokukhawuleza ukunikezelwa kombane kwimeko ye-single-phase-grounding short circuit okanye i-grounding fault ku-low-voltage network network, ngaloo ndlela iqinisekisa ukhuseleko lomntu kunye nezixhobo zokukhusela ekonakalisweni.

2. Kwimeko yokungaphumeleli ngaxeshanye kwitshintshi yokukhusela ukuvuza kunye nezixhobo zombane, impazamo yokuvuza kwisixhobo sombane inokususwa ngokukhethayo ukuze ingabangeli ilahleko epheleleyo yombane, ngaloo ndlela iqinisekisa ukhuseleko lomntu kunye nokuthintela ukwandiswa kombane. iingozi zombane.

3. Kwinqanaba lesithathu leentambo ezine-low-voltage power grid, xa i-single-phase-grounding fault yenzeke, ukunikezelwa kombane kunokunqunyulwa ngokukhawuleza nangexesha lokuthintela ukwandiswa kwengozi.

4. Ukukhethwa kokutshintshwa kokukhusela ukuvuza kuhle kakhulu ngenxa yemisebenzi yayo emibini yokukhululwa kwe-overcurrent (TN -C) kunye nokukhululwa kwe-overload (TT-B).

5. Xa iingongoma ezimbini zemoto zisekelwe ngenxa yokutshatyalaliswa kombane womntu okanye ngenxa yesizathu esithile, ukunikezelwa kombane kunokunqunyulwa ngokukhawuleza nangokuthembekileyo.

Musa ukusebenzisa umbane wesigaba esinye ekukhanyiseni.

Ukufakela ukukhuselwa kokuvuza: 1. Ukufakwa komkhuseli wokuvuza kufuneka kuhambelane nemimiselo efanelekileyo, indawo yayo kufuneka ibe yomelele kwaye inokwethenjelwa, kwaye kufuneka ivalwe njengoko kufuneka.

2. Ireyithingi yomkhuseli wokuvuza iya kumiselwa ngumsebenzisi ngokosetyenziso oluthile, kodwa ngokubanzi ayisayi kudlula umbane osebenza ngokukhuselekileyo (30mA).

3. Imodeli kunye neenkcukacha zomkhuseli wokuvuza uya kufaneleka kumgca wokudibanisa.

4. Iitheminali zomkhuseli wokuvuza kunye neziphelo zombini zomgca womthwalo ziya kuba noqhagamshelwano olulungileyo kwaye ziya kuqina kwaye zithembeke.

5. Ukuba kufunyaniswe kusetyenziswa ukuba umkhuseli wokuvuza unengxolo engaqhelekanga, ukunyuka kwamaqondo obushushu, imvakalelo yesandla engaqhelekanga, njl. njl., umntu osebenza ngombane uya kufunyanwa ngexesha elifanelekileyo ukuze ahlolwe kwaye alungiswe.

6. Izikhuseli zokuvuza aziyi kusetyenziswa ixesha elide kwaye ngokubanzi aziyi kusetyenziswa ngaphezulu kwesiqingatha sonyaka.Ukuba kuyimfuneko ukuqhubeka nokusebenzisa abo bakhuseli, baya kuhlolwa ngokupheleleyo ngaphambi kokuba basetyenziswe.

Ayinakuthatha indawoukuvuza kwesekethe umaphulikunye nesokethi eqhelekileyo.

Ngenxa yokuba i-socket eqhelekileyo ngokwayo iqokobhe lesinyithi kunye nokugquma kweengcingo zangaphakathi azikwazi ukudlala indima yokukhusela, ngoko xa ukuvuza kwenzeka, umbane uya kungena emzimbeni ngesokethi, ekhokelela kwingozi yokutshatyalaliswa kombane.

Ukusetyenziswa kombane ngokukhuselekileyo kubaluleke kakhulu.Ayikhathaleli kuphela ukhuseleko lwethu, kodwa nabantu abasingqongileyo.Ukuba awuyi kuqwalasela ukusetyenziswa kombane kwinkqubo yokhuseleko, ukungakhathali okuncinci kuya kubangela ukutshitshiswa kombane.Ngoko ke, kubomi bemihla ngemihla kufuneka baphuhlise umkhwa olungileyo wombane okhuselekileyo.

Umtshini wokukhusela ukuvuza unokuqonda isilumkiso somlilo kwangethuba, ukujonga umlilo wombane, ukulahla umlilo wombane kunye neminye imisebenzi.Ukutshintshwa kokukhusela ukuvuza kunokufakwa kwigumbi lokusabalalisa kunokufakwa kwimfuno nganye yokukhusela indawo, kunokunciphisa ngokufanelekileyo amathuba okuba neengozi ezibangelwa ukuvuza.

Xa usebenzisa iukuvuza kwesekethe umaphuli, le miba ilandelayo iya kuqatshelwa:

1. Ngaphambi kokufaka i-circuit breaker evuzayo, kuyimfuneko ukujonga ngokucophelela ukuba imbonakalo kunye nemigca yokudibanisa i-breaker circuit breaker ilungile kwaye ingaba iingcingo ezisetyenzisiweyo zihambelana neenkcukacha.Ukulinganisa ukuba ixabiso langoku lokulandelelana kwe-zero ye-breaker circuit breaker iphakathi koluhlu oluqhelekileyo, akufanele kubekho into engaqhelekanga engaqhelekanga phambi kokuba i-breaker circuit breaker isebenze.

2. Xa ufaka i-breaker circuit breaker, ingqwalasela iya kuhlawulwa ekusebenziseni ngokuchanekileyo i-fuse enexabiso elilinganisiweyo langoku kwaye umbane kufuneka unqunyulwe ngaphambi kokukhangela umkhuseli wokuvuza.Ukuvuza kweesekethe zokuvuza akufanele kusetyenziswe ukuba isiphaluka sangaphandle singena kwigumbi okanye ukuba kukho impazamo emfutshane.

3. Xa ufaka i-circuit breaker evuzayo, i-circuit breaker iya kufakwa kwinqanaba kunye nomhlaba oqinileyo kwaye uxhomekeke ngokuthembekileyo okanye u-zeroed.

4. Emva kokufakela, i-breaker circuit breaker iya kuvavanywa rhoqo ngokuqhawula umbane, kwaye ukuba ayikwazi ukuxhunywa phakathi kwemizuzu emi-2, umbane unokudibaniswa kwakhona.
