A I-circuit breakeriyiswishi engaxhuma futhi inqamule isekethe.Ngokwemisebenzi yayo ehlukene, ingahlukaniswa ngama-air circuit breaker kanye ne-gas-insulated metal-enclosed switchgear (GIS).
Izinzuzo ze-circuit breaker: isakhiwo esilula, intengo eshibhile, ingathuthukisa kakhulu izinga lokwakhiwa kwephrojekthi;umthamo omkhulu wokuphuka, umthamo oqinile wokugcwala ngokweqile, ukuxhuma okungavamile kanye nokuphulwa komugqa;umsebenzi wokuvikela ophelele, unganqamula ngokushesha umjikelezo ngesikhathi esifushane kakhulu.
Ukungalungi kwama-breaker circuit: ukushisa okukhulu nokukhanya okuphezulu kwe-arc kukhiqizwa ngesikhathi sesifunda esifushane;imisebenzi kaningi ayikwazi ukwenziwa;isikhathi esanele siyadingeka ukuze insimbi eku-fuse ibuyele endaweni encibilikayo.
Lapho i-I-circuit breakeriguqulwa isuke ekushintsheni yomoya iye ku-GIS, kuzohlangatshezwana nemithethonqubo elandelayo:
I-1) I-breaker circuit kumele isekelwe kahle ngesikhathi sokufakwa nokusetshenziswa;
I-2) Ukushisa okuhle kufanele kugcinwe phakathi kwe-switchgear ye-GIS kanye nomhlabathi;
3) Indawo yokufaka kufanele ibe nezinsiza ezinhle zokudonsa amanzi.
Umsebenzi
A I-circuit breakeriyiswishi esetshenziselwa ukuvula nokuvala isekethe, futhi ngokuvamile inomsebenzi wokuvula nokuvala isekethe, futhi inemisebenzi efana nokuvikela isekethe emfushane nokuvikela ukugcwala kakhulu.Ngesikhathi esifanayo, ikhono layo lokuphuka linamandla kakhulu, futhi lingakwazi ukusika ngokushesha isifunda ngesikhathi esifushane kakhulu.
1. Njengedivayisi yokusabalalisa amandla aphansi-voltage, i-breaker circuit inomsebenzi wokuvikela isifunda ekulayisheni ngokweqile, i-short circuit kanye ne-undervoltage.
2. I-breaker circuit inezinzuzo zekhono eliqinile lokusika isenzo samanje nesisheshayo;iphinde ibe nomsebenzi wokuvikela isekethe emfishane ye-short-circuit current yokuphuka kwesigaba esisodwa.
3. Njengedivayisi yokusabalalisa amandla kagesi aphansi, i-circuit breaker ingavala noma inqamule umjikelezo wokusebenza kwamandla okusebenza okuvamile phakathi nesikhathi esishiwo;inganikeza amandla ngokuqhubekayo kulayini ngaphandle kokwehluleka, futhi ingasetshenziswa njenge-motor stator insulation kanye nesekethe uma kunesidingo.Amasekhethi asizayo ezinto ezihlukahlukene zikagesi.
Faka
1. Ngaphambi kokufaka, hlola ukubukeka kwe-circuit breaker ukuze uthole imifantu, bese uvula isembozo sokugcina se-circuit breaker, bese uhlola ukuhlonza kanye ne-nameplate esembozweni sokugcina.Hlola ngokumelene nemodeli eshiwo kubhukwana lomkhiqizo.
2. Ukufakwa kwe-circuit breaker kufanele kuhlangabezane nezidingo zokuklama, futhi kufanele kuhambisane nendawo yokufaka ezinye izinto zikagesi kuphaneli yokusabalalisa amandla noma idivayisi yokusabalalisa amandla.Akuvunyelwe ukufaka noma ukudlula eduze kwezinye izinto zikagesi nezinto ezisebenza ngogesi (amaswishi).
3. I-circuit breaker kanye nezinsiza zayo kufanele zisekelwe ngokuthembekile.Ukuze uthole izintambo ezinezingqimba eziningi, isokhethi ephezulu kanye nongqimba lokuvikela ikhebula kufanele kubekwe phansi.
4. Indlela yokusebenza kufanele ihlolwe ngomthwalo ngaphambi kokuhlakazwa ukuze kuqinisekiswe ukuthi isenzo sayo siyavumelana nezimo futhi sithembekile ngaphambi kokuhlakazwa.Hlola ukuthi izintambo zilungile yini ngaphambi kokuhlehliswa, ngaphandle kwalokho azikwazi ukuhlakazwa ngokungaboni.
5. Uma i-breaker circuit ifakwe ebhokisini lensimbi, ama-bolts okubopha ebhokisini awavunyelwe ukukhulula;uxhumano phakathi kwamabholithi okulungisa ibhokisi kanye nentambo kufanele kube okuthembekile;amantongomane okulungisa kufanele abe yizikulufa zokulwa nokukhulula;imigodi yesikulufu kufanele ibhojwe ngomshini;
Vikela
Uma isistimu ihluleka, njengokugcwala kwemoto, i-short circuit, njll., izingozi ezinkulu nemiphumela emibi ingagwenywa, okudinga ukusetshenziswa kwama-circuit breaker ukuvikela imishini kagesi noma amasekhethi emonakalweni.Kodwa-ke, i-circuit breaker ayikwazi ukufeza ngempela "i-maintenance-free".Kwezinye izimo, ukunakekelwa okuthile kusadingeka.
1. Uma uhambo lwe-overcurrent lwenzeka ngesikhathi sokusebenza kwe-circuit breaker, hlola ukuthi ingabe ezinye izinto zikagesi zisesimweni esihle sokusebenza;
2. Hlola ukusebenza kwedivayisi yokuvikela ukuvuza, futhi kufanele isebenze ngaphansi kwezimo ezijwayelekile zokusebenza;
3. Uma indlela yokusebenza kagesi ihluleka, hlola ukuxhumanisa phakathi kwendlela yokusebenza kagesi kanye ne-circuit breaker;
4. Uma iphutha le-short-circuit lenzeka kulayini, ukunikezwa kwamandla kufanele kunqanyulwe;
5. Ngenxa yokuguga kwe-insulation yangaphakathi ye-circuit breaker ngemva kokusebenza isikhathi eside.Ngakho-ke, i-circuit breaker kufanele igcinwe njalo.
Izinyathelo zokuzivikela
1. Indlela yokusebenza kufanele ithembeke ukugwema izingozi.Kufanele kube nezinkomba ezisobala nezenzo zesenzo sengxenye ngayinye kumshini, futhi ukungasebenzi kahle kufanele kugwenywe.
2. Ukuze i-circuit breaker isebenze, noma ngabe isibambo saso sisesimweni sokukhubeka, i-arcing isengenzeka koxhumana nabo noma kumasekethe okuvula nokuvala.Ukunakekelwa kufanele kuthathwe ukuze kuvinjelwe ukusebenzisa kabi ngesikhathi sokusebenza.
3. Lapho i-circuit breaker isebenza (ikakhulukazi lapho inqamula umsinga omkhulu), ayikwazi ukudonswa ngenkani, ukuze ingalimazi izingxenye zikagesi.
4. I-circuit breaker kufanele ihlale ihlola izimo zayo zokuvula nokuvala ukuze zigweme amaphutha e-overvoltage noma ama-undervoltage.
5. Uma kwenzeka iphutha, zama ukubuyisela ugesi owawunqamukile kuqala.
