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 "Inkcazo yoBuchule boKhuseleko lwaMandla okwethutyana", i-breaker yesiphaluka yamandla okwethutyana kwindawo yokwakha kufuneka ibe yiqokobhe esobala, inokwahlula ngokucacileyo imeko yoqhagamshelwano ephambili, kunye nesekethe yokuthotyelwa. ibreaker mayincanyathiselwe uphawu “AJ” olukhutshwe lisebe lokhuseleko elichaphazelekayo.

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. okanye umjelo wesekethe ixesha elide udlula isantya sangoku sesaphuli sesekethe ukuya kuhambo, ngoko ke ikwabizwa ngokuba yi-double tripping, edla ngokusetyenziswa kwiimeko eziqhelekileyo zokuhanjiswa kwamandla. I-breaker magnetic tripping current, i-hot tripping current, kunye nexesha lokuhamba liyakwazi ukulungelelaniswa, amaxesha asebenzayo ngokubanzi, kodwa ixabiso le-breaker circuit liphezulu. Ukongeza kwezi ntlobo zintathu zingentla zezixhobo zokukhubeka, ngaphezu koko, kukho isekethe i-breaker isetyenziselwa ngokukodwa ukhuseleko lwesekethe yemoto. 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.
