A umephuli wojikelezolutshintsho olunokuthi ludibanise kwaye lukhuphe isekethe.Ngokutsho kwemisebenzi yayo eyahlukeneyo, inokwahlulwa ibe yi-air circuit breakers kunye ne-gas-insulated metal-enclosed switchgear (GIS).
Iingenelo ze-breaker circuit: isakhiwo esilula, ixabiso elincinci, linokuphucula kakhulu umgangatho wokwakhiwa kweprojekthi;umthamo omkhulu wokuqhawula, umthamo oqinileyo womthwalo, ukudibanisa okungaqhelekanga kunye nokuphulwa komgca;umsebenzi opheleleyo wokukhusela, unokunqumla ngokukhawuleza isiphaluka ngexesha elifutshane kakhulu.
Ukungalungi kwabaphuli beesekethe: ukushisa okukhulu kunye nokukhanya okuphezulu kwe-arc kuveliswa ngexesha lesiphaluka esifutshane;imisebenzi rhoqo ayinakwenziwa;ixesha elaneleyo lifunekayo ukuze isinyithi kwi-fuse sibuyele kwindawo yokunyibilika.
Xa iumephuli wojikelezoiguqulwa ukusuka kumatshini womoya ukuya kwi-GIS, le migaqo ilandelayo iya kuhlangatyezwana nayo:
1) I-breaker circuit kufuneka isekelwe kakuhle ngexesha lofakelo kunye nokusetyenziswa;
2) Ukugquma okulungileyo kufuneka kugcinwe phakathi kwe-GIS switchgear kunye nomhlaba;
3) Indawo yokufakela kufuneka ibe nezixhobo ezilungileyo zokuhambisa amanzi.
Umsebenzi
A umephuli wojikelezosisitshixo esisetyenziselwa ukuvula nokucima isiphaluka, kwaye ngokuqhelekileyo sinomsebenzi wokuvula nokucima isekethe, kwaye sinemisebenzi efana nokukhusela isiphaluka esifutshane kunye nokukhusela umthwalo ogqithiseleyo.Ngelo xesha, ukuphulwa kwayo kunamandla kakhulu, kwaye kunokukhawuleza ukunqumla isiphaluka ngexesha elifutshane kakhulu.
1. Njengesixhobo sokusabalalisa amandla aphantsi-i-voltage, i-breaker circuit inomsebenzi wokukhusela isiphaluka kwi-overload, i-short circuit kunye ne-undervoltage.
2. I-circuit breaker ineenzuzo zokukwazi okunamandla ukunqumla isenzo sangoku kunye nokukhawuleza;ikwanayo nomsebenzi wokukhusela i-short-circuit current ye-short-circuit current ye-fracture yesigaba esinye.
3. Njengesixhobo sokusabalalisa umbane ophantsi-voltage, i-breaker circuit ingavala okanye ikhuphe isiphaluka sombane osebenzayo oqhelekileyo ngaphakathi kwexesha elichaziweyo;iyakwazi ukubonelela ngokuqhubekayo amandla kumgca ngaphandle kokusilela, kwaye ingasetyenziselwa njenge-motor stator insulation kunye nesiphaluka xa kuyimfuneko.Iisekethe ezincedisayo kwizixhobo ezahlukeneyo zombane.
Faka
1. Ngaphambi kokufakela, jonga ukubonakala kwesiphakeli sesekethe ngenxa yokuqhekeka, emva koko uvule isiciko sokugqibela sesiphakeli sesiphaluka, kwaye ukhangele ukuchongwa kunye ne-nameplate kwi-cover yokugqibela.Jonga ngokuchasene nemodeli echazwe kwincwadana yemveliso.
2. Ukufakwa kwe-breaker circuit kufuneka kuhlangabezane neemfuno zokuyila, kwaye kufuneka kuhambelane nendawo yokufakela ezinye izixhobo zombane kwiphaneli yokusabalalisa amandla okanye isixhobo sokuhambisa amandla.Akuvumelekanga ukufaka okanye ukudlula kufuphi nezinye izixhobo zombane kunye nezixhobo (iiswitshi).
3. I-breaker circuit kunye nezixhobo zayo kufuneka zisekelwe ngokuthembekileyo.Kwi-wiring ye-multi-layer, i-socket ephezulu kunye ne-cable shielding layer kufuneka ibekwe phantsi.
4. Inkqubo yokusebenza kufuneka ifakwe kuvavanyo lomthwalo ngaphambi kokuqhawulwa ukuze kuqinisekiswe ukuba isenzo sayo siguquguqukayo kwaye sinokuthenjwa ngaphambi kokuchithwa.Khangela ukuba i-wiring ichanekile na phambi kokuba uqhaqhe, kungenjalo ayinakuchithwa ngokungaboniyo.
5. Xa i-circuit breaker ifakwe kwibhokisi yensimbi, i-bolts yokuqinisa kwibhokisi ayivumelekanga ukuba ikhulule;uxhulumaniso phakathi kweebholiti zokulungisa ibhokisi kunye nentambo kufuneka ithembeke;amantongomane okulungisa kufuneka abe yi-screws anti-loosening;imingxuma ye-screw kufuneka igrunjwe ngoomatshini;
Khusela
Xa inkqubo ingaphumeleli, njenge-motor overload, isiphaluka esifutshane, njl., iingozi ezinkulu kunye nemiphumo emibi inokuphetshwa, efuna ukusetyenziswa kweesekethe zokukhusela izixhobo zombane okanye iisekethe kumonakalo.Nangona kunjalo, i-breaker circuit ayikwazi ukuphumeza ngokwenene "i-maintenance-free".Kwezinye iimeko, ulondolozo oluthile lusafuneka.
1. Xa uhambo oludlulayo lwenzeka ngexesha lokusebenza kwe-circuit breaker, khangela ukuba ezinye izixhobo zombane zisebenza kakuhle;
2. Khangela ukusebenza kwesixhobo sokukhusela ukuvuza, kwaye kufuneka sisebenze phantsi kweemeko eziqhelekileyo zokusebenza;
3. Xa umbane wokusebenza ungasebenzi, khangela ulungelelwaniso phakathi kwendlela yokusebenza yombane kunye ne-circuit breaker;
4. Xa i-short-circuit iphutha lenzeka kumgca, ukunikezelwa kwamandla kufuneka kunqanyulwe;
5. Ngenxa yokuguga kwe-insulation yangaphakathi ye-breaker circuit emva kokusebenza kwexesha elide.Ngoko ke, i-breaker circuit kufuneka igcinwe rhoqo.
Ukulumkela
1. Indlela yokusebenza kufuneka ithembeke ukuphepha iingozi.Kufuneka kubekho izalathisi ezicacileyo kunye nezenzo zesenzo secandelo ngalinye kwindlela, kwaye ukungasebenzi kufuneka kuthintelwe.
2. Kwi-circuit breaker esebenzayo, nokuba isibambo saso sikwimeko yokukhwela, i-arcing isenokuthi yenzeke kubafowunelwa okanye kwiisekethe zokuvula nokuvala.Kufuneka kuthathelwe ingqalelo ukuthintela ukusetyenziswa kakubi ngexesha lokusebenza.
3. Xa i-circuit breaker isebenza (ngokukodwa xa usika umsinga omkhulu), awukwazi ukutsalwa ngokunyanzeliswa, ukuze ungonakalisi amacandelo ombane.
4. I-breaker yesekethe kufuneka ihlale ihlola iimeko zayo zokuvula kunye nokuvala uqhagamshelwano ukuze ugweme ukugqithisa okanye iimpazamo eziphantsi kwe-undervoltage.
5. Xa kusenzeka impazamo, zama ukubuyisela ukucinywa kombane kuqala.
