Yini aukuvuza kwe-circuit breaker?
Ukuvuza kwe-circuit breaker, isetshenziselwa ukuvimbela ukushaqeka kukagesi.Lapho ukuvuza kwenzeka, inkambu kazibuthe ikhiqizwa othintana naye oyinhloko, ikhoyili yokuxhumana ehlukanisayo, ikhoyili yokuxhumana ehlukanisayo kanye neswishi eyinhloko.
Ukuvuza kwe-circuit breakerumsebenzi: lapho isifunda esifushane noma ukulayishwa ngokweqile kungaba isenzo esifike ngesikhathi, nqamula ukunikezwa kwamandla.
Uma kukhona isivikelo sokuvuza kusekethe, uma iphutha lokuvuza noma ukugcwala ngokweqile kwenzeka, isivikeli sokuvuza ngeke sisebenze futhi sizothumela isignali ye-alamu yomsindo neyokukhanya.Akukho ukunqanyulwa mathupha okudingekayo.
Izinjongo eziyinhloko:
1. Ukuvikela ukuphepha komuntu siqu lapho kuvuza impahla kagesi yasendlini noma ehlangene.
2. Izofakwa ezindaweni zomphakathi nasezindaweni ezivutha umlilo neziqhumayo (njengama-workshops, izindawo zokugcina impahla, njll.) lapho abantu bevame ukuthutha ukuze bavimbele umlilo nezinye izingozi ezibangelwa ukuvuza kukagesi.
Ayikwazi ukwabelana ngomthombo wamandla nezinye izisetshenziswa zikagesi.
1. Iswishi yokuvikela ukuvuza inganqamula ngokushesha ukunikezwa kwamandla uma kwenzeka kuba nesigaba esisodwa sokumisa isifunda esifushane noma iphutha lokumisa kunethiwekhi yamandla aphansi, ngaleyo ndlela iqinisekise ukuphepha komuntu siqu nokokusebenza kokuvikela ukuthi kungonakaliswe.
2. Uma kwenzeka ukwehluleka kanyekanye kokushintshwa kokuvikela ukuvuza kanye nemishini kagesi, iphutha lokuvuza ezintweni zikagesi lingasuswa ngokukhetha ukuze kungabangela ukulahlekelwa okuphelele kwamandla kagesi, ngaleyo ndlela kuqinisekiswe ukuphepha komuntu siqu futhi kuvimbele ukwanda izingozi zikagesi.
3. Esigabeni sesithathu segridi yamandla aphansi we-voltage yezintambo ezine, lapho kwenzeka iphutha lesigaba esisodwa, ukunikezwa kwamandla kunganqanyulwa ngokushesha nangesikhathi ukuvimbela ukwanda kwengozi.
4. Ukukhethwa kweswishi yokuvikela ukuvuza kuhle kakhulu ngenxa yemisebenzi yayo emibili yokukhululwa kwe-overcurrent (TN -C) kanye nokukhululwa kokulayisha ngokweqile (TT-B).
5. Lapho amaphuzu amabili enjini esekelwe ngenxa yokushaqeka kukagesi womuntu siqu noma ngesizathu esithile, ukunikezwa kwamandla kunganqanyulwa ngokushesha nangokuthembekile.
Ungasebenzisi ugesi wesigaba esisodwa ukukhanyisa.
Ukufakwa kokuvikela ukuvuza: 1. Ukufakwa kwesivikelo sokuvuza kufanele kuhambisane nemithethonqubo efanele, indawo yaso kufanele iqine futhi ithembekile, futhi kufanele ikhiywe njengoba kudingeka.
2. Isilinganiso sesivikeli sokuvuza sizonqunywa umsebenzisi ngokuya ngokusetshenziswa okuqondile, kodwa ngokuvamile angeke seqe amandla asebenzayo aphephile (30mA).
3. Imodeli kanye nokucaciswa kwesivikeli sokuvuza kuzofaneleka ulayini wokuxhuma.
4. Amatheminali okuvikela ukuvuza kanye neziphetho zombili zolayini wokulayisha zizoxhumana kahle futhi ziqine futhi zithembeke.
5. Uma kutholakala ekusebenziseni ukuthi isivikeli sokuvuza sinomsindo ongavamile, ukunyuka kwezinga lokushisa, ukuzwa kwesandla okungavamile, njll., osebenza ngogesi uzotholwa ngesikhathi ukuze ahlolwe futhi alungiswe.
6. Izivikeli zokuvuza ngeke zisetshenziswe isikhathi eside futhi ngokuvamile ngeke zisetshenziswe isikhathi esingaphezu kwesigamu sonyaka.Uma kudingekile ukuqhubeka nokusebenzisa abavikeli abanjalo, bayohlolwa ngokugcwele ngaphambi kokusetshenziswa.
Ayikwazi ukumiselelaukuvuza kwe-circuit breakerngesokhethi evamile.
Ngenxa yokuthi isokhethi evamile ngokwayo igobolondo lensimbi kanye nokufakwa kwezintambo zangaphakathi akukwazi ukudlala indima yokuzivikela, ngakho-ke lapho ukuvuza kwenzeka, ugesi uzongena emzimbeni ngesokhethi, okuholela engozini yokushaqeka kagesi.
Ukusebenzisa ugesi ngendlela ephephile kubaluleke kakhulu.Akuthinti ukuphepha kwethu kuphela, kodwa futhi nabantu abasizungezile.Uma unganaki ukusetshenziswa kukagesi ohlelweni lokuphepha, ukunganaki okuncane kuzoholela ekushayweni kagesi.Ngakho-ke, ekuphileni kwansuku zonke kufanele ahlakulele umkhuba omuhle kagesi ophephile.
Iswishi yokuvikela ukuvuza ingabona isexwayiso sokuqala komlilo kagesi, ukuqapha umlilo kagesi, ukulahlwa komlilo kagesi neminye imisebenzi.Ukuvuza ukuvikela switch ingafakwa ekamelweni ukusatshalaliswa ingafakwa futhi isidingo ngasinye ukuvikela indawo, kunganciphisa ngempumelelo ematfuba ezingozi ezibangelwa ukuvuza.
Uma usebenzisa i-aukuvuza kwe-circuit breaker, lezi zindaba ezilandelayo zizoqashelwa:
1. Ngaphambi kokufaka i-circuit breaker evuzayo, kuyadingeka ukuhlola ngokucophelela ukuthi ukubukeka nemigqa yokuxhuma ye-circuit breaker evuzayo ilungile nokuthi izintambo ezisetshenzisiwe ziyahlangabezana yini nezincazelo.Ukuze ulinganise ukuthi ingabe inani lamanje lokulandelana kweziro le-breaker circuit elivuzayo lingaphakathi kwebanga elivamile, akumele kube khona into engavamile esobala ngaphambi kokuthi i-breaker circuit evuzayo isebenze.
2. Lapho ufaka i-circuit breaker evuzayo, kufanele kuqashelwe ukusetshenziswa okufanele kwe-fuse enevelu yamanje elinganiselwe futhi ugesi kufanele unqanyulwe ngaphambi kokuhlola isivikelo sokuvuza.Ama-breaker circuit avuzayo akufanele asetshenziswe uma isifunda sangaphandle singena ekamelweni noma uma kwenzeka iphutha le-short-circuit.
3. Uma ufaka i-circuit breaker evuzayo, i-circuit breaker izobekwa endaweni esezingeni futhi eqinile futhi isekelwe ngokuthembekile noma i-zeroed.
4. Ngemuva kokufakwa, i-breaker circuit breaker izohlolwa njalo ngokunqamula ukunikezwa kwamandla, futhi uma ingakwazi ukuxhunywa phakathi nemizuzu engu-2, ukunikezwa kwamandla kungaxhunywa futhi.
