Naka amaphuzu alandelayo lapho ufaka ama-low-voltage circuit breaker:
I-1.Ngaphambi kokufaka i-breaker circuit, kuyadingeka ukuhlola ukuthi i-oil stain endaweni yokusebenza ye-armature isuliwe, ukuze ingaphazamisi ukusebenza kwayo kahle.
2.Lapho ufaka i-circuit breaker, kufanele ifakwe iqonde ukuze igweme ukuthikameza ukunemba kwesenzo kanye nekhono lokuvala lokukhululwa, futhi ukuvikelwa kokufakwa kufanele kufakwe.
3.Lapho itheminali ye-circuit breaker ixhunywe kubha yebhasi, akukho ukucindezelwa kwe-torsion okuvunyelwe, futhi ukufaneleka kwevelu yokukhubeka kwesiyingi esifushane kanye nenani lokukhubeka elishisayo kufanele kuhlolwe.
4. Ulayini ongenayo wokunikezwa kwamandla kufanele uxhunywe ekhanda lekholomu engenhla ohlangothini lwegumbi lokucisha i-arc, futhi ulayini ophumayo womthwalo kufanele uxhunywe ekhanda lekholomu engezansi ohlangothini lokukhululwa, kanye nolayini wokuxhuma indawo efanele ephambanayo kufanele ikhethwe ngokuvumelana nemithethonqubo ukuze kugwenywe ukuthikameza uhambo oludlulele.Izici zokuvikela ze-clasp.
5.I-wiring yendlela yokusebenza kanye nendlela kagesi ye-breaker circuit kumele ilungile.Ngesikhathi sokusebenza kukagesi, ukugxuma kokushintsha kufanele kugwenywe, futhi isikhathi sokusebenza kwamandla akufanele sidlule inani elishiwo.
6.Ngesikhathi sokuvala nokuvula othintana nabo, akumele kube khona ukugxuma phakathi kwengxenye ehambayo kanye nezingxenye zegumbi le-arc.
7.Indawo yokuxhumana yothintana naye kufanele ibe isicaba, futhi othintana naye kufanele aqine ngemva kokuvala.
8.Inani lohambo lwesifunda esifushane kanye nenani lohambo olushisayo kufanele lusethwe ngendlela efanele ngokuya ngezidingo zomugqa kanye nomthwalo.
9.Ngaphambi kokusetshenziswa, sebenzisa i-500V megohmmeter ukukala ukumelana nokufakwa phakathi komzimba ophilayo nohlaka, phakathi kwezigxobo, naphakathi kohlangothi lwamandla kanye nohlangothi lomthwalo lapho i-breaker yesifunda inqanyulwa.Qinisekisa ukuthi ukumelana nokufakwa kwe-insulation kukhulu noma kulingana no-10MΩ (i-marine circuit breaker Hhayi ngaphansi kuka-100MΩ).
Okulandelayo yizimfuneko zezintambo ze-low-voltage circuit breaker:
1.Ezindaweni zocingo ezivezwe ngaphandle kwebhokisi futhi zifinyeleleka kalula, ukuvikelwa kokushisa kuyadingeka.
2.Uma i-low-voltage circuit breaker inedivayisi yokukhubeka ye-semiconductor, izintambo zayo kufanele zihlangabezane nezidingo zokulandelana kwesigaba, futhi isenzo sedivayisi yokukhubeka kufanele sithembeke.
Okulandelayo yizidingo zokufaka, ukulungisa kanye nokuhlola ama-DC ashesha ama-circuit breaker: 1. Ngesikhathi sokufakwa, kuyadingeka ukuvimbela i-circuit breaker ukuthi ingagingqiki, ingqubuzane futhi idlidlize okunodlame, futhi uthathe izinyathelo ezifanele zokulwa nokudlidliza phakathi kwensimbi yesiteshi sesisekelo kanye isisekelo.
2 .Ibanga phakathi kwezikhungo zezigxobo ze-breaker yesekethe kanye nebanga lezinto zokusebenza eziseduze noma izakhiwo akufanele libe ngaphansi kuka-500 mm.Uma le mfuneko ingenakufinyelelwa, kuyadingeka ukufaka umgoqo we-arc obude bungekho ngaphansi kobude obuphelele bokushintsha kwesigxobo esisodwa.Kufanele kube nesikhala esingekho ngaphansi kuka-1000mm ngaphezu kwegumbi lokucisha i-arc.Uma le mfuneko ingenakufinyelelwa, lapho ukuguqulwa kwamanje kungaphansi kwama-amps angu-3000, kuyadingeka ukufaka isihlangu se-arc 200 mm ngaphezu kwesiphazamisi se-breaker circuit;Faka ama-arc baffles.
3.I-insulating lining egumbini lokucisha i-arc kumele libe liphelele futhi i-arc passage kumele ivuleke.
I-4.Ingcindezi yokuxhumana, ibanga lokuvula, isikhathi sokuphuka, kanye nokumelana nokufakwa phakathi kwesikulufu sokusekela segumbi lokucima i-arc kanye nokuxhumana ngemva kokulungiswa kokuxhumana okuyinhloko kufanele kuhlangabezane nezidingo zemibhalo yezobuchwepheshe yomkhiqizo.
