Ingabe isixhumi se-voltage ephansi kufanele sisale ngemuva kwe-low voltage circuit breaker?

Ingabe kukhona umbono onjalo wokuthi i-disconnector iyizinga eliphansi, futhi i-breaker circuit iyizinga eliphezulu, lapho i-disconnector isetshenziswa khona, i-breaker circuit ingasetshenziswa esikhundleni salokho?Lo mbono uyaphikiswana ngawo, kodwa izinqamuli kanye nama-circuit breaker anezinhlelo zawo zokusebenza.

I-low voltage circuit breaker iyisisetshenziswa somshini sokushintsha esingakwazi ukwenza, ukuthwala, futhi sinqamule amandla ngaphansi kwezimo ezivamile zesekhethi, futhi singakwazi nokwenza, ukuthwala, nokunqamula amandla akhona isikhathi esithile ngaphansi kwezimo ezingavamile njengokujikeleza okufushane.Ama-breaker voltage circuit breaker angahlukaniswa abe ama-frame circuit breaker (ACB), ama-molded case circuit breaker (MCCB) nama-micro circuit breaker (MCB).I-voltage ephansi ye-isolator switch inomsebenzi we-isolator nokushintsha.Okokuqala, inomsebenzi wokuzihlukanisa.Ngesikhathi esifanayo, ingaxhunywa, imelane futhi iphule umthwalo wamanje ngaphansi kwezimo ezivamile.Okusho ukuthi, iswishi ye-isolator inomsebenzi wakho kokubili isihlukanisi nokushintsha.

Umsebenzi we-isolator ukunqamula ukunikezwa kwamandla kagesi noma impahla kagesi.Ngesikhathi esifanayo, ungabona iphuzu elicacile lokunqamula.Isihlukanisi asikwazi ukuvikela ulayini noma okokusebenza.Kodwa ukushintshwa akusho ukuthi kunomsebenzi wokuzihlukanisa, kunomsebenzi wokushintsha nokuvala umthamo wamanje, ungamelana nenkathi ethile yamanje yesifunda esifushane.Isibonelo, iswishi ye-semiconductor ayikwazi ukusetshenziswa njengesihlukanisi, ngenxa yokuthi izinto zikagesi ze-semiconductor azihlukanisiwe, okweqa izimfuneko zokuvuza kwamanje kwe-isolator kungaphansi kuka-0.5mA, ngakho-ke i-semiconductor akufanele isetshenziswe njenge-isolator. isihlukanisi.

Eqinisweni, kunezinhlelo zokusebenza eziningi ze-switch isolator, kodwa kwezinye izindawo, ukusetshenziswa kwe-isolator switch ithathelwa indawo yi-breaker circuit, ikakhulukazi emkhakheni wezomphakathi, ongagcini nje ngokuhluleka ukuklama nokwakhiwa ngokuhambisana nezidingo ukucaciswa, kodwa futhi kwandisa izindleko zephrojekthi.Izicelo zeswishi yokunqamula zimi kanje:

(1) Ikhabhinethi yokusabalalisa eyinhloko ephezulu ivikelwe ama-circuit breaker noma ama-fuse, futhi imodi yokuphakelwa kwamandla yohlobo lwe-radiation iyamukelwa ukuze ingene endlini.Alikho igatsha maphakathi nolayini wokuphakela amandla.I-cable inlet switch kwikhabhinethi yokusabalalisa kufanele ihlukaniswe.

(2) Izinto ezisetshenziswayo ezihlukanisayo kufanele zisethwe kuyisekethe eyinhloko yezintambo ezimbili zokungena kwamandla kagesi wensimbi yokusika yomthombo kagesi kabili, futhi kufanele kusetshenziswe amaswishi akhethekile ahlukanisayo.

(3) ukuthi iKhabhinethi yokusabalalisa amandla kagesi aphansi idinga ukufakwa ngokuhlukile idinga ukuhlaziywa okuthile, uma ikhabethe lokusatshalaliswa kwamandla kagesi eliphansi liyikhabethe lamadrowa, awukwazi ukumisa umshini wokuhlukanisa abantu, ngoba ikhabhinethi yabadwebi ingaba yisekethe. i-breaker kanye nokunye ukuphuma okuphelele;Uma iKhabhinethi yokusabalalisa i-voltage ephansi iyikhabhinethi engaguquki, inkinobho yokunqamula kufanele ifakwe noma i-circuit breaker enomsebenzi wokuhlukanisa kufanele isetshenziswe.

(4) Ulayini ongenayo ophelele webhokisi legatsha lekhebula kufanele usebenzise iswishi ekhethekile yokunqamula, futhi isifunda segatsha ngasinye kufanele sisebenzise iswishi yokunqamula yohlobo lwe-fuse noma i-MCCB enomsebenzi ophelele wokuhlukanisa.

Ngamafuphi, ukuze kube lula ukugcinwa, ukuhlolwa kanye nokulungiswa kabusha kwezintambo zikagesi noma impahla kagesi, kubalulekile ukufaka inkinobho yokunqamula endaweni okulula ukuyisebenzisa futhi okulula ukuyibona.
