Izindlela Ezinhle Zokulungisa Nokuhlola Ze-ACB Circuit Breaker

Ezinhlelweni zokusatshalaliswa kwamandla aphansi, ama-air circuit breaker adlala indima ebalulekile ekuvikeleni imishini kagesi nokuqinisekisa ukuqhubeka kokusebenza. Ukugcinwa nokuhlolwa okufanele kubalulekile ukuqinisekisa ukusebenza okuthembekile, ikakhulukazi ezicelweni ezinezilinganiso zamanje eziphezulu kanye nokusebenza okushintsha njalo. Ngokusebenzisa izinqubo zokuhlola nokuhlola ezijwayelekile, abaqhubi banganciphisa kakhulu ingozi yokwehluleka okungalindelekile kanye nesikhathi sokungasebenzi esibizayo.

1. Ukuhlolwa Okubonakalayo Okuvamile kanye Nezinqubo Zokuhlanza

Ukuhlolwa njalo ngokubona kwakha isisekelo sokugcinwa okuphumelelayo kokuvimbela. Ukuqongelela uthuli, ukungena komswakama, kanye nezimpawu zokushisa ngokweqile konke kungonakalisa ukusebenza kokuvikela kanye nokuthembeka kwemishini.
Imisebenzi ebalulekile yokuhlola ihlanganisa:

• Ukuhlola izindawo zangaphandle ukuthi azinamifantu, zigqwalile, noma izikhonkwane ezikhululekile

• Ukuhlola ama-arc chutes kanye nezithiyo zokuvimbela ukungcola noma umonakalo

• Ukuhlanza izingxenye zangaphakathi usebenzisa amathuluzi omile, angahambisi ugesi

Ezindaweni zezimboni ezinzima, kunconywa ukuhlolwa okuphindaphindiwe ukuze kulondolozwe izimo zokusebenza ezifanele.

2. Ukuhlolwa Kokusebenza Kwemishini kanye Nokuhlolwa Kwesimo Sokuxhumana

Ubuqotho bemishini buthinta ngqo ikhono le-breaker lokuvula nokuvala kahle ngesikhathi sezinkinga. Ukuhlolwa kwemishini okuvamile kufanele kuqinisekise:

• Ukusebenza kahle kwezindlela ezisetshenziswa ngesandla nezisebenzisa injini

• Ukuqondanisa kahle izingxenye ezihambayo kanye nezinhlangano zokunamathela

• Amazinga okuguguleka kokuthintana nesimo sobuso

Ukuguguleka okukhulu kokuthintana kungandisa ukumelana nokukhiqizwa kokushisa, okwenza ukuhlolwa kanye nokufakwa esikhundleni ngesikhathi esifanele kubalulekile ukuze kube nokuthembeka kwesikhathi eside.

3. Izindlela Zokuhlola Ugesi Zokuqinisekisa Ukusebenza Okuthembekile

Ukuhlolwa kukagesi kuqinisekisa ukuvikelwa kokushisa kanye nekhono lokuthwala ugesi ledivayisi. Ukuhlolwa okuvamile kufaka phakathi:

• Ukulinganisa ukumelana nokufakwa kwe-insulation ukuthola ukonakala kokufakwa kwe-insulation

• Ukuhlolwa kokumelana kokuxhumana ukuze kutholakale izingozi zokushisa ezingavamile

• Ukuhlolwa kokumelana ne-dielectric ukuqinisekisa amandla okuvikela ukufudumala

Imiphumela yokuhlola kufanele iqhathaniswe njalo ngokuqhathanisa nemininingwane yomkhiqizi kanye nedatha yomlando ukuze kutholakale izimpawu zokuqala zokuwohloka.

4. Ukuqinisekiswa Kwezilungiselelo Zokuvikela kanye Nokuhlolwa Kokusebenza

Izilungiselelo zokuvikela ezifanele ziqinisekisa ukuthi i-breaker isabela ngendlela efanele ekugcwaleni ngokweqile, kuma-short circuits, kanye namaphutha omhlaba. Imikhuba emihle ihlanganisa:

• Ukuqinisekisa izilungiselelo zohambo lwesikhathi eside, lwesikhathi esifushane, nolwesikhathi esifushane

• Ukwenza ukuhlolwa kwesibili kokufakwa komjovo ukuqinisekisa ukunemba kokudluliselwa

• Ukwenza izivivinyo zohambo olusebenzayo ngaphansi kwezimo zamaphutha ezilingisiwe

Ukuxhumana okufanele namadivayisi okuvikela asezingeni eliphezulu naphansi kubalulekile ukuze kugwenywe ukuphazamiseka kwesistimu okungadingekile.

5. Imvamisa Yokulungisa, Amadokhumenti, kanye Nezinyathelo Zokuphepha

Izikhawu zokulungisa kufanele zinqunywe yizimo zokusebenza, amazinga omthwalo, kanye nemvamisa yokushintsha. Konke ukuhlolwa nokuhlolwa kufanele kubhalwe phansi ngokucophelela, kufaka phakathi amanani okuhlola kanye nezinyathelo zokulungisa ezithathiwe.
Izinto okufanele uzicabangele ngokuphepha nazo zibaluleke ngokulinganayo:

• Landela izinqubo zokukhiya/ukukhiya (LOTO) ngaphambi kokulungisa

• Sebenzisa imishini yokuzivikela efanele (i-PPE)

• Qinisekisa ukuhambisana nezindinganiso ze-IEC kanye ne-IEEE ezifanele

Imibhalo ehambisanayo isekela ukuhlolwa kokuhambisana nomthetho futhi ithuthukisa izinqumo zokuphathwa kwempahla.

Isiphetho

Uhlelo lokulungisa nokuhlola oluhlelekile lubalulekile ukuqinisekisa ukuthembeka kwesikhathi eside kwe-I-ACB Circuit BreakerNgokuhlola njalo, ukuhlolwa kwemishini nogesi, kanye nokubhala imibhalo enembile, abaphathi bezikhungo bangathuthukisa ukuphepha kwesistimu, bandise isikhathi sokuphila kwemishini, futhi banciphise isikhathi sokungasebenzi esingahleliwe ezinhlelweni ezibalulekile zokusabalalisa amandla.

Izinkomba

Imibuzo Evame Ukubuzwa

Q1: Kufanele kugcinwe kangaki i-air circuit breaker?
A: Imvamisa yokulungisa incike ezimweni zokusebenza, kodwa ukuhlolwa kwaminyaka yonke kuvamile ezindaweni ezivamile, ngokuhlolwa okuvamile kwezicelo ezinzima noma ezisebenza kakhulu.

Umbuzo 2: Kungani ukuhlolwa kokumelana nokuxhumana kubalulekile?
A: Ukumelana okuphezulu kokuthintana kungabangela ukushisa ngokweqile futhi kunciphise ukusebenza kahle kwe-breaker, okwenza ukutholakala kusenesikhathi kube yinto ebalulekile.

Umbuzo 3: Ingabe ukulungiswa kungenziwa ngenkathi uhlelo lusebenza?
A: Cha. Yonke imisebenzi yokulungisa kufanele yenziwe ngaphansi kwezimo zokuphelelwa amandla ngokulandela izinqubo zokuphepha ezifanele.

UMBUZO 4: Yiziphi izindinganiso okufanele zilandelwe ukulungiswa?
A: Izindinganiso zomhlaba wonke ezifana ne-IEC 60947-2 kanye nemikhuba efanele enconyiwe ye-IEEE kufanele ilandelwe njalo.
