Isakhono sokukhetha i-MCCB

Isaphuli sesekethe iqokobhe leplastiki (igobolondo iplastiki air insulated ibreaker circuit) isetyenziswa ngokubanzi kwishishini lokuhambisa amandla aphantsi-voltage, esetyenziselwa ukunqumla okanye ukwahlula uluhlu oluqhelekileyo kunye noluhlu lwempazamo yangoku, ukuqinisekisa ukhuseleko lwemigca kunye nezixhobo.Ukongeza, ngokweemfuno zaseTshayina "zeNdawo yoLwakhiwo lweXesha loKhuseleko loBugcisa boBuchwephesha", indawo yolwakhiwo lwamandla okwethutyana kufuneka ibe yiqokobhe ecacileyo, inokwahlula ngokucacileyo indawo ephambili yokwahlula unxibelelwano, kwaye isaphuli sesekethe sokuthotyelwa kufuneka sincanyathiselwe " AJ” uphawu olukhutshwe lisebe lokhuseleko elifanelekileyo.
I-QF ukumela umaphuli wesekethe, imizobo yangaphandle ebizwa ngokuba yi-MCCB.Iindlela ezixhaphakileyo zeplastiki zesaphuli sesekethe sokukhubeka kunye neendlela zokukhubeka kukukhubeka okukodwa kumagnethi, ukukhubeka okushushu kumagnethi (ukukhubeka kabini), ukukhubeka nge-elektroniki.Ukuhamba ngemagnethi enye kuthetha ukuba umaphuli wesekethe uhamba kuphela xa isekethe inesiphako esifutshane sesekethe.Sidla ngokusebenzisa olu tshintsho kwiluphu yesifudumezi okanye iluphu yemoto enomsebenzi wokukhusela umthwalo ogqithisileyo.I-Thermal magnetic tripping yimpazamo yesiphaluka esifutshane okanye umsinga wesekethe udlula umlinganiselo okhoyo wesaphuli sesekethe ixesha elide lokuhamba, ngoko ke ikwabizwa ngokuba kukukhubeka kabini, okuhlala kusetyenziswa kwizihlandlo eziqhelekileyo zokuhanjiswa kwamandla.Ukuhamba nge-elektroniki bubuchwephesha obuvuthiweyo obuvela kwiminyaka yakutshanje, kunye ne-electronic tripping circuit breaker magnetic tripping current, i-hot tripping current, kunye nexesha lokuhamba ziyahlengahlengiswa, amaxesha asebenzayo ngokubanzi, kodwa ixabiso le-breaker circuit liphezulu.Ukongeza kwezi ntlobo zintathu zingasentla zezixhobo zokukhubeka, kukho ibreaker yesekethe esetyenziselwa ngokukodwa ukhuseleko lwesekethe yemoto, imagnethi yayo yangoku ikhubayo ingaphezulu kwamaxesha ali-10 angoku, ukunqanda incopho yangoku xa imoto iqala, ukuqinisekisa 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 indlela yokusebenza yombane, qwa lasela ingqalelo kufuneka ihlawulwe kwisakhelo sesakhelo sesakhelo sesekethe yesekethe yangoku, kuba ubungakanani bangaphandle besakhelo sesakhelo seqokobhe esahlukileyo sangoku kunye netorque yendlela yokuvala yahlukile.
Xa ukhetha ikhoyili yokuvuselela, nikela ingqalelo kwinqanaba le-voltage yesignali ekude kunye namanqaku e-AC kunye ne-DC.Iingcebiso zobuqu xa sisenza uyilo, ukuba isiginali ekude ikwinqanaba le-24V, zama ukungasebenzisi i-coil yokuvuselela i-voltage ekude, ngenxa yokuba ukusetyenziswa kwamandla e-coil e-excitation, kunokuzisa uxinzelelo kwisignali ekude, ukuba indawo yohambo ingaphezulu, izixhobo ezikude. Amandla akonelanga ukwenza lula ukubangela ukwehla koxinzelelo lwe-breaker breaker coil voltage, kwaye akakwazi ukugudisa i-buckle kwaye ibiyi-coil yokuvuselela yombane.Ngeli xesha, siya kusebenzisa i-24V encinci ye-intermediate relay ye-relay, khetha inqanaba lombane we-220V, kwaye sihambe amandla asekuhlaleni kwikhoyili yokuvuselela.
Abafowunelwa abancedisayo bahlulwe babancedisi ababodwa kunye nabancedisi kabini, kwaye iisampulu zikhethwa ngokwenani lemfuno yenyani yokugcina iindleko zokuyila.
Uninzi lwabafowunelwa be-alamu bafuna ukunikezelwa kwamandla okusebenza kwangaphandle kunye nokuqinisekiswa ngexesha lokuzoba kunye nokudibanisa.
Lo mfanekiso ulandelayo ikhowudi yasekhaya yeplastiki iqokobhe isiqhekezi isiqhoboshi, indibaniselwano kunye nekhowudi brand attachment kumazwe angaphandle ngocwangco ngakumbi musa uluhlu, ujonga ngqo iisampuli brand efanelekileyo.
Kwinkqubo yoyilo, kaninzi ukuhlangabezana nekhabhinethi idinga igobolondo esisigxina, kodwa umthwalo awuvumeli ukusilela kwamandla ngaphandle kwesizathu.Emva koko sinokusebenzisa i-plug-in circuit breaker, apho i-circuit breaker iphosakele ngokuthe ngqo inokuthi ithathe indawo enye, ayichaphazeli enye isiphaluka sombane oqhubekayo.
Faka isiseko se-breaker circuit kwisakhiwo somzimba
Esinye isalathiso esibalulekileyo sentsebenzo yesaphuli sesekethe yeplastiki silinganiswe kwisakhono esifutshane sesekethe esaphukileyo, esichaphazela ngokuthe ngqo ukhuseleko lwesekethe yokhuseleko lwangoku, ngokubanzi 25/35/50/65 kh.Kweyona nkqubo yokukhetha, sinokukhetha ngokweemfuno zemizobo yeziko loyilo, kwaye singakwazi ukubala ubuninzi obulindelekileyo bexabiso elikhoyo lesekethe emfutshane ye-loop ngokweva.I-breaker-short circuit breaking capacity iya kuba nkulu kunobuninzi obulindelekileyo be-short circuit current ye-circuit.Ukuze kugcinwe iindleko, ixabiso lesakhono sesekethe esifutshane lilungile ngokwaneleyo.
