A I-circuit breakeriyiswishi engaxhuma futhi inqamule isekethe. Ngokwemisebenzi yayo ehlukene, ingahlukaniswa ibe ama-air circuit breaker kanye ne-gas-insulated metal-enclosed switchgear (GIS).
Izinzuzo ze-circuit breaker: isakhiwo esilula, intengo ephansi, ingathuthukisa kakhulu ikhwalithi yokwakha yephrojekthi; amandla amakhulu okuphuka, amandla amakhulu okulayisha ngokweqile, ukuxhumana okungajwayelekile kanye nokuphuka komugqa; umsebenzi wokuvikela ophelele, inganqamula isekethe ngokushesha ngesikhathi esifushane kakhulu.
Okubi ngama-circuit breaker: ukushisa okukhulu kanye nokukhanya okuphezulu kwe-arc kukhiqizwa ngesikhathi se-short circuit; imisebenzi evame ukwenziwa ayikwazi ukwenziwa; kudingeka isikhathi esanele ukuze insimbi e-fuse ibuyele endaweni yokuncibilika.
LaphoI-circuit breakeruma iguqulwa kusuka kuswishi lomoya iye kwi-GIS, imithetho elandelayo kufanele ihlangatshezwe:
1) I-circuit breaker kumele ibe nesisekelo esihle ngesikhathi sokufakwa nokusetshenziswa;
2) Ukuvikela okuhle kufanele kugcinwe phakathi kwe-GIS switchgear kanye nomhlabathi;
3) Indawo yokufaka kufanele ibe nezindawo ezinhle zokukhipha amanzi.
Umsebenzi
A I-circuit breakeriyiswishi esetshenziselwa ukuvula nokuvala isekethe, futhi ngokuvamile inomsebenzi wokuvula nokuvala isekethe, futhi inemisebenzi efana nokuvikela isekethe emfushane nokuvikela ukulayisha ngokweqile. Ngesikhathi esifanayo, ikhono layo lokuphuka linamandla kakhulu, futhi linganqamula isekethe ngokushesha ngesikhathi esifushane kakhulu.
1. Njengedivayisi yokusabalalisa amandla ane-voltage ephansi, i-circuit breaker inomsebenzi wokuvikela i-circuit ekugcwaleni ngokweqile, i-short circuit kanye ne-undervoltage.
2. I-circuit breaker inezinzuzo zekhono elinamandla lokunqamula ugesi kanye nesenzo esisheshayo; futhi inomsebenzi wokuvikela ugesi omfushane wogesi omfushane wokuqhekeka kwesigaba esisodwa.
3. Njengedivayisi yokusabalalisa amandla ane-voltage ephansi, i-circuit breaker ingavala noma inqamule i-circuit yokunikezwa kwamandla okusebenza okuvamile ngaphakathi kwesikhathi esibekiwe; ingahlinzeka ngamandla njalo entanjeni ngaphandle kokwehluleka, futhi ingasetshenziswa njenge-motor stator insulation kanye ne-circuit uma kudingeka. Ama-circuit asizayo emishini kagesi eyahlukahlukene.
Faka
1. Ngaphambi kokufaka, hlola ukubukeka kwe-circuit breaker ukuze kungabikho imifantu, bese uvula isembozo sokugcina se-circuit breaker, bese uhlola ukuhlonza kanye ne-nameplate esembozweni sokugcina. Hlola ngokumelene nemodeli echazwe encwadini yomkhiqizo.
2. Ukufakwa kwe-circuit breaker kufanele kuhlangabezane nezidingo zomklamo, futhi kufanele kuhambisane nendawo yokufaka yeminye imishini kagesi kuphaneli yokusabalalisa amandla noma idivayisi yokusabalalisa amandla. Akuvunyelwe ukufaka noma ukudlula eduze kweminye imishini kagesi nezinto zikagesi (amaswishi).
3. I-circuit breaker kanye nezesekeli zayo kumele zisekelwe ngokuqinile. Ukuze kube nezintambo eziningi, isokhethi ephezulu kanye nesendlalelo sokuvikela ikhebula kufanele futhi kusekelwe ngokuqinile.
4. Indlela yokusebenza kufanele ihlolwe umthwalo ngaphambi kokuyiqaqa ukuqinisekisa ukuthi ukusebenza kwayo kuyaguquguquka futhi kuthembekile ngaphambi kokuyiqaqa. Hlola ukuthi izintambo zilungile yini ngaphambi kokuyiqaqa, ngaphandle kwalokho ayikwazi ukuqaqa ngaphandle kolwazi.
5. Uma i-circuit breaker ifakiwe ebhokisini lensimbi, amabhawodi okubopha ebhokisini awavunyelwe ukukhululeka; ukuxhumana phakathi kwamabhawodi okulungisa ibhokisi kanye nentambo kufanele kube okuthembekile; amantongomane okulungisa kufanele abe yizikulufo ezivimbela ukukhululeka; imigodi yezikulufo kufanele ibholwe ngomshini;
Vikela
Uma uhlelo luhluleka, njengokugcwala ngokweqile kwenjini, i-short circuit, njll., izingozi ezinkulu nemiphumela emibi kakhulu kungagwenywa, okudinga ukusetshenziswa kwama-circuit breaker ukuvikela imishini kagesi noma ama-circuit ekulimaleni. Kodwa-ke, i-circuit breaker ayikwazi ngempela "ukuthola ukunakekelwa". Kwezinye izimo, kusadingeka ukulungiswa okuthile.
1. Uma kwenzeka ukuqhuma komsinga ngesikhathi sokusebenza kwe-circuit breaker, hlola ukuthi ezinye izinto zikagesi zisesimweni esihle sokusebenza yini;
2. Hlola ukusebenza kwedivayisi yokuvikela ukuvuza, futhi kufanele isebenze ngaphansi kwezimo zokusebenza ezijwayelekile;
3. Uma indlela yokusebenza kagesi yehluleka, hlola ukuhlangana phakathi kwendlela yokusebenza kagesi kanye ne-circuit breaker;
4. Uma kwenzeka iphutha le-short-circuit entanjeni, ugesi kufanele unqanyulwe;
5. Ngenxa yokuguga kokufakwa kokushisa kwangaphakathi kwe-circuit breaker ngemva kokusebenza isikhathi eside. Ngakho-ke, i-circuit breaker kufanele inakekelwe njalo.
Izinyathelo zokuzivikela
1. Indlela yokusebenza kumele ithembeke ukuze kugwenywe izingozi. Kufanele kube nezinkomba nezenzo ezicacile zesenzo sengxenye ngayinye emshinini, futhi ukungasebenzi kahle kufanele kuvinjelwe.
2. Uma i-circuit breaker isebenza, noma ngabe isibambo sayo sisesimweni sokukhubeka, ukugoba kungase kwenzeke ezindaweni ezixhumanayo noma ezisekelweni zokuvula nokuvala. Kumelwe kuqashelwe ukuvimbela ukusebenza kabi ngesikhathi sokusebenza.
3. Uma i-circuit breaker isebenza (ikakhulukazi uma inqamula ugesi omkhulu), ayikwazi ukudonswa ngenkani, ukuze ingalimazi izingxenye zikagesi.
4. I-circuit breaker kufanele ihlole njalo izimo zayo zokuvula nokuvala ukuze igweme amaphutha e-overvoltage noma i-undervoltage.
5. Uma kwenzeka iphutha, zama ukubuyisela ugesi onqanyuliwe kuqala.
