Umthamo wokuqhekeza, kwelinye icala, ubhekisa kumbane ophezulu wempazamo onokuphazanyiswa yi-breaker ngokukhuselekileyo. Umthamo owaneleyo wokuqhekeza ubalulekile ekuthinteleni umonakalo ngexesha leziganeko ze-short-circuit. Ukukhetha i-MCCB enomlinganiselo ofanelekileyo wokuphazamisa kuqinisekisa ukwahlulwa kwempazamo okusebenzayo kwaye kukhusela izixhobo ezisezantsi kuxinzelelo olukhulu lombane.

2. Iindlela zoKhuselo lweThermal kunye neMagnetic zichaziwe

Ukhuseleko lwe-thermal-magnetic luphawu oluphambili lwe-molded case circuit breakers. Ukhuseleko lwe-thermal luphendula kwiimeko zokuxinana kwexesha elide ngokusebenzisa i-bimetal element egobayo xa ubushushu bunyuka, nto leyo ebangela ukuba unyawo lulibaziseke. Le ndlela inceda ekuthinteleni ukugqithisa kakhulu kweentambo kunye nezixhobo ezixhunyiweyo.

Ukhuseleko lwemagnethi luphendula ngoko nangoko kwimisinga yesekethe emfutshane ephezulu. Xa kuvela ukunyuka okukhulu ngequbuliso, indlela yemagnethi yokujika isebenza ngoko nangoko, iqhawule isekethe ngaphambi kokuba kwenzeke umonakalo omkhulu. Ukusebenza okudibeneyo kwezi ndlela zombini kuqinisekisa ukhuseleko olupheleleyo phantsi kweemeko ezahlukeneyo zempazamo.

3. Uyilo oluQhelekileyo kunye noHlanganiso oluLula kwiiphaneli zoMbane

Ukusebenza kakuhle kwendawo yeyona nto ibalulekileyo ekuyilweni kwepaneli yombane yanamhlanje. Ii-MCCB ezine-compact form factor zivumela abafaki ukuba bandise umthamo wepaneli ngaphandle kokubeka emngciphekweni ukhuseleko. Ubukhulu bazo obuqhelekileyo bokufakelwa kunye nezixhobo zemodyuli zenza kube lula ukuhlanganiswa kwiindlela ezahlukeneyo zokucwangcisa iipaneli.

Ukongeza, uyilo lwe-terminal olusebenziseka lula kunye neelebheli ezicacileyo zenza kube lula ukufakela, ukuhlola kunye nokugcina izinto zisebenza. Oku kunceda ekunciphiseni ixesha lokungasebenzi kunye nokunciphisa iindleko zokusebenza kuyo yonke inkqubo.

4.Izicelo kwiinkqubo zorhwebo nezezindlu

Olu vavanyo lwangoku lusetyenziswa rhoqo kwizakhiwo zorhwebo ezifana neeofisi, iindawo zokuthenga, kunye namagumbi amancinci edatha, apho kufuneka khona usasazo lwamandla oluzinzileyo lokukhanyisa, iinkqubo ze-HVAC, kunye nemithwalo eqhelekileyo. Kwiindawo zokuhlala, lufanelekile kwii-feeders eziphambili okanye iibhodi zokusasaza ezincinci kumakhaya amakhulu okanye kwii-apartment complexes.

Ikwasetyenziswa rhoqo kwiindawo zoshishino ezilula, apho imithwalo yoomatshini ephakathi kunye neenkqubo ezincedisayo zifuna ukhuseleko oluthembekileyo noluqhubekayo.

5. Indlela Ephucula Ngayo Ukhuseleko Lwenkqubo Nokuthembeka Kokusebenza

Ngokubonelela ngokhuseleko oluchanekileyo lokugqithisa umthwalo kunye nokhuseleko lwe-short-circuit, i-I-100 Amp MCCB Inciphisa kakhulu umngcipheko womlilo wombane kunye nokusilela kwezixhobo. Ikhusela iintambo, iiphaneli, kunye nemithwalo eqhagamshelweyo ngelixa igcina inkonzo iqhubeka phantsi kweemeko zokusebenza eziqhelekileyo.

Ngaphezu koko, ukuthobela imigangatho yamazwe ngamazwe eyaziwayo kuphucula ukuthembeka kwenkqubo iyonke kwaye kuqinisekisa ukusebenza okuzinzileyo kwexesha elide kwiindawo ezahlukeneyo zombane.

Isiphelo

I-MCCB eyilwe kakuhle idlala indima ebalulekileyo ekukhuseleni iiphaneli zombane kunye neenkqubo eziqhagamshelweyo. Ngomlinganiselo ofanelekileyo wangoku, amandla okuqhekeka athembekileyo, kunye nokhuseleko olusebenzayo lwe-thermal-magnetic, olu hlobo lwe-circuit breaker lubonelela ngesisombululo esisebenzayo kwiintlobo ngeentlobo zezicelo. Ukukhetha ngononophelo kunye nokufakelwa ngokuchanekileyo kunceda ukuqinisekisa ukhuseleko, ukusebenza kakuhle, kunye nokuthobela iinkqubo zanamhlanje zokusasaza umbane.
