Iimpawu zoLwakhiwo
1. I-MCB ikakhulu iqulunqwe yindlela yokusebenza, uqhagamshelwano oluguquguqukayo kunye ne-static, iyunithi yohambo, isixhobo sokucima i-arc kunye namanye amacandelo.Kwaye zonke zifakwe kwiqokobhe le-insulating elenziwe ngokumelana okuphezulu komile, iplastiki enokumelana nempembelelo.
2. Xa utyhala isibambo sokusebenza kwindawo ethi "ON", indlela yokusebenza ivala abafowunelwa abahambayo kunye ne-static ukuvala isiphaluka.Xa i-overload iphosakele kumgca, i-overload yangoku ibangela ukuba i-bimetal element ye-thermal igobe kwaye i-vertebral ehambayo ye-lever iphinda ibuyisele umatshini wokuvala umatshini, kwaye uqhagamshelwano oluhambayo lushiya ngokukhawuleza umnxeba we-static, ngaloo ndlela ufezekise ukukhuselwa kokugqithiswa komgca;xa impazamo yesiphaluka esifutshane yenzeka kumgca, i-short circuit current ibangela i-tripper esheshayo , Intonga yokutyhala ityhala i-lever ukusetha kwakhona indlela yokuvala ukuphumeza ukhuseleko olufutshane lwesiphaluka.
3. I-2P, 3P kunye ne-4P i-circuit breakers ixhotyiswe ngesixhobo sokudibanisa ukudibanisa, kwaye isibambo sokusebenza sixhunywe ngentonga yokudibanisa, engayi kubangela ingozi yesiphaluka esisodwa.
4. Ipali nganye inesalathisi sokutshintsha isimo sokusebenza
Imeko yokusebenza eqhelekileyo
1. Ubushushu bomoya we-Ambient: -5 ° C ~ + 40 ° C, kwaye ixabiso eliqhelekileyo kwiiyure ezingama-24 alidluli +35 ° C.
2. Ukuphakama: Ukuphakama kwendawo yofakelo akudluli kwi-2000m.
3. Iimeko ze-atmospheric: umswakama ohambelana nomoya awudluli i-50% kwiqondo lokushisa +40 ° C;Ukufuma okuphezulu okunxulumene nobushushu kuvumelekile kumaqondo obushushu asezantsi, kwaye i-avareji ephezulu yokufuma enxulumene nenyanga emanzi kakhulu yi-90%, kunye nenyanga yenyanga Ubuncinci beqondo lokushisa alidluli +20 ° C, kwaye kufuneka kuqwalaselwe ukufuma okwenzekayo. kumphezulu wemveliso ngenxa yokutshintsha kobushushu.
4. Isidanga songcoliseko: Iqondo longcoliseko leMCB linqanaba lesi-2.
5. Udidi lofakelo (i-overvoltage category): Udidi lofakelo lwe-MCB ngu-II.
6. Ifakwe kwindawo ngaphandle kwempembelelo ebalulekileyo kunye nokungcangcazela, akukho ndawo yokudubula eyingozi, akukho khefu lomoya okanye uthuli olwaneleyo lokutshabalalisa isinyithi kunye nokutshabalalisa i-insulation, akukho mvula kunye nokuhlaselwa kwekhephu.
7. Iimeko zokufakela: I-TH35 iileyili zesikhokelo eziqhelekileyo zisetyenziselwa ukufakwa kunye nokufakwa kwikhabhinethi yokusabalalisa amandla kunye nebhokisi lokuhambisa.Xa ufaka, kufuneka ifakwe ngokuthe nkqo, kunye nesibambo ukuya kwindawo yokubeka amandla.
Imilo kunye nemilinganiselo yoFakelo
Ufakelo, Ukusetyenziswa kunye noLondolozo
1. Ufakelo
◇ Ngexesha lofakelo, khangela ukuba idatha yobugcisa esisiseko yenameplate iyazanelisa na iimfuno zokusetyenziswa.
◇ Jonga iMCB uze uyisebenzise izihlandlo ezininzi.Isenzo siya kuba bhetyebhetye kwaye sithembeke.Ufakelo lunokwenziwa kuphela emva kokuqinisekisa ukuba lukhuselekile.
◇ I-MCB kufuneka ifakwe ngokungqinelana neemfuno ezimiselweyo.Isiphelo esingenayo sisecaleni lonikezelo lwamandla ngaphezu kwe-breaker, kwaye isiphelo esiphumayo sisecaleni lomthwalo ngaphantsi kwe-MCB, indawo ephezulu yesibambo yindawo evaliweyo yoqhagamshelwano.
◇ Xa ufaka, qala ufake i-MCB kwi-TH35 yesiporo sokunyusela esisemgangathweni.Emva koko faka iingcingo ezingenayo neziphumayo kwi-terminal, kwaye usebenzise izikrufu ukufikelela kwi-MCB.Ummandla onqamlekileyo wentambo yokudibanisa ekhethiweyo kufuneka ihambelane nesantya esilinganisiweyo (jonga iThebhile 3).
| Ilinganiswe ngoku A | ≤6 | 10 | 15 | 20 | 25 | 32 | 40 | 50 | 63 |
| Indawo yecandelo lomqhubi mm2 | 1 | 1.5 | 2.5 | 2.5 | 4.0 | 6.0 | 10 | 10 | 16 |
2. Ukusetyenziswa kunye nokugcinwa
◇ Iimpawu ezikhuselayo ze-MCB ziyakumiselwa ngumenzi, kwaye aziyi kulungelelaniswa ngokuthanda ngexesha lenkqubo yokusetyenziswa ukunqanda ukuchaphazela ukusebenza.
◇ Emva kokuba i-MCB iluhambo ngenxa yokugcwala okanye ukhuseleko olufutshane lwesekethe, impazamo iya kususwa kuqala kwaye emva koko i-MCB iya kuvalwa.Xa uvala, isiphatho siya kutsalwa ezantsi ukwenza isixhobo sokusebenza siphinde “sibophe”, emva koko sityhalelwe phezulu ukuze sivale.
◇ Xa ukhuseleko lomthwalo omninzi lwe-MCB lwaphukile kwaye impazamo isusiwe, kufuneka kube malunga nemizuzu eli-10 phambi kokuba kuvalwe.
◇ I-MCB iya kuhlolwa rhoqo ngexesha lokusebenza.Ubonelelo lwamandla luya kunqunyulwa ngexesha lokuhlolwa.
◇ I-MCB ayisayi kuhlaselwa kwaye iwiswe yimvula nekhephu ngexesha lokusetyenziswa, ukugcinwa okanye ukuthuthwa.
Ukuodola Imiyalelo
Umsebenzisi kufuneka achaze oku kulandelayo xa eodola:
