Ungayikhetha njani i-MCCB?

I-shell shell circuit breaker (igobolondo yeplastiki i-air insulated circuit breaker) isetyenziswa ngokubanzi kwishishini lokusabalalisa i-voltage ephantsi, esetyenziselwa ukunqumla okanye ukwahlula uluhlu oluqhelekileyo kunye noluhlu lwempazamo yangoku, ukuqinisekisa ukhuseleko lwemigca kunye nezixhobo. ngokweemfuno zeTshayina "iNgcaciso yoBugcisa boKhuseleko lwaMandla okwethutyana", isaphuli sesekethe samandla okwethutyana kwindawo yokwakha kufuneka sibe neqokobhe esobala, inokwahlula ngokucacileyo imeko yoqhagamshelwano ephambili, kwaye umaphuli wesekethe wokuthotyelwa kufuneka ancanyatheliswe ngophawu "AJ" ikhutshwe lisebe lokhuseleko elifanelekileyo.

QF isetyenziswa ngokubanzi ukumela umaphuli wesekethe, kwaye imizobo angaphandle zibizwa ngokubanzi ngokuba MCCB.Common iplastiki iqokobhe yesekethe sesekethe iindlela zokukhubeka kukukhubeka magnetic enye, ukukhubeka magnetic eshushu (ikhube kabini), tripping electronic.Single magnetic ukukhubeka kuthetha ukuba isekethe i-breaker kuphela iihambo xa isekethe inokusilela kwesekethe emfutshane, kwaye siqhele ukusebenzisa olu tshintsho kwiluphu yesifudumezi okanye isekethe yemoto enokhuseleko olugqithisiweyo. yangoku yesaphuli sesekethe ukuya kuhambo, ngoko ke ikwabizwa ngokuba kukukhubeka kabini, okusoloko kusetyenziswa ngamaxesha aqhelekileyo okuhanjiswa kwamandla.Ukunyathela nge-elekthronikhi bubugcisa obuqolileyo obuvela kwiminyaka yakutshanje, kunye ne-electronic tripping circuit breaker magnetic tripping current, i-hot-tripping current, kunye ixesha lokuhamba lihlehliswa, amaxesha asebenzayo ngokubanzi, kodwa ixabiso le-breaker circuit liphezulu.Ukongezwa kwezi ntlobo zintathu zingentla zezixhobo zokukhwela, ngaphezu koko, kukho i-breaker circuit esetyenziselwa ngokukodwa ukukhusela i-motor circuit.Umjelo wayo wokuhamba ngemagnethi ngokubanzi ungaphezulu kwamaxesha ali-10 angoku ukunqanda isantya esiphezulu sangoku xa i-motor iqala kwaye iqinisekisa ukuba i-motor iqala kakuhle kwaye i-breaker circuit ayihambi.

Iqhekeza leplastiki yesekethe yesekethe inezixhobo ezahlukeneyo ezinokuxhonywa, ezifana nesixhobo sokutshintsha umbane esikude, ikhoyili yokuvuselela, unxibelelwano oluncedisayo, ukunxibelelana kwe-alarm, njl.

Xa ukhetha umatshini wokusebenza kombane, ingqalelo kufuneka ihlawulwe kwisakhelo sesakhelo sesakhelo sesekethe esixhasayo, kuba ubungakanani bangaphandle besakhelo esahlukileyo sesakhelo sesakhelo sesakhelo sangoku kunye netorque yendlela yokuvala yahlukile.
