MLM1 Mulang Electric kwisigaba sesithathu-sine-wire switch yomoya MLM1 MCCB main gate switch of MCCB

amagqabantshintshi
I-MLM1 yochungechunge lwecala leplastiki yesaphuli sesekethe (emva koku kubhekiselwa kuyo njengesaphuli sesekethe), ilungele i-AC 50Hz okanye i-60Hzits ekalikelwe umbane wokufakelwa kwe-insulation yi-800V (MLM1-63 yi-500V), umbane osebenzayo olinganisiweyo yi-690V (MLM1-63 yi-400V nangaphantsi), isetyenziselwa ukutshintshela okungaqhelekanga kunye nokuqala okungaqhelekanga kweenjini kwiisekethe kunye nokusebenza okulinganiselwe ngoku ukuya kwi-1250A (Inm <630Aand ngaphantsi) .I-breaker circuit ine-overload, isiphaluka esifutshane kunye nemisebenzi yokukhusela i-undervoltage enokukhusela isekethe kunye nezixhobo zokubonelela umbane kumonakalo.
Izaphuli zesekethe zahlulwe zaba ziindidi ezintathu: uhlobo lwe-L (uhlobo oluqhelekileyo), iMtype(uhlobo oluphezulu lokuqhawuka), kunye nohlobo lwe-H (uhlobo oluqhawukayo oluphezulu) ngokomlinganiselo wabo olinganiselweyo wokuqhekeka kwesekethe emfutshane. Isaphuli sesekethe sineempawu zobukhulu obuncinci, ukophuka okuphezulu kwe-flashover, i-anti-vibration, njl. Yimveliso efanelekileyo yomhlaba kunye neenqanawa.
I-breaker circuit inokufakwa ngokuthe nkqo (oko kukuthi ufakelo oluthe nkqo) okanye ngokuthe tye (oko kukuthi, ufakelo oluthe tye).
I-breaker circuit ihlangabezana nemigangatho: EC60947-2 kunye neGB14048.2

Qaphela: Kukho iintlobo ezine zepali engathathi hlangothi (i-N pole yemveliso yeepali ezine
Uhlobo lwe-N-pali aluxhotyiswanga ngento yokukhubeka,
Kwaye iN pole isoloko iqhagamshelwe, kwaye ayivali kwaye ivuleke ngezinye iipali ezintathu;
Udidi lwe-N-pali alufakelwanga lunezinto ezikhubekayo zangoku,
Ipali ye-N idityaniswe nezinye izibonda ezintathu;
Ipali yohlobo lwe-N ixhotyiswe ngezinto ezikhubekayo ngoku,
Ipali ye-N idityaniswa nezinye izibonda ezintathu;(Ipali engu-N idityaniswa kuqala ize yahlulwe):
Ipali ye-D yohlobo lwe-N ixhotyiswe nge-element yokukhulula i-overcurrent, kwaye i-Npole ihlala iqhagamshelwe, kwaye ayivali kwaye ivule nezinye iipali ezintathu;

iimeko eziqhelekileyo zokusebenza
Ubushushu obujikelezayo obuphakathi: bungekho ngaphezulu kwe +40°C(+45*C kwiimveliso ezisetyenziswa ngokuqhelekileyo)kwaye bungekho ngaphantsi kwe -5°C, kwaye ixabiso eliqhelekileyo leeyure ezingama-24 alidluli +35C(+40°C kwiimveliso ezisetyenziswa ngokuqhelekileyo) ;
Indawo yokufakela: ukuphakama akudluli kwi-2000m;
Indawo yokufakela: Ukufuma komoya okuhambelanayo akudluli kwi-50% xa elona qondo lobushushu liphezulu +40 ° I-Cand inokuba nobushushu obuphezulu ngokwentelekiso kwiqondo lobushushu elisezantsi, umzekelo, inokufikelela kwi-90% kwi-20 ° c; ukuxinana ngamaxesha athile ngenxa yotshintsho lobushushu Kufuneka kuthathwe amanyathelo akhethekileyo;
Inqanaba longcoliseko: Inqanaba lesi-3;
Udidi lofakelo: Udidi lofakelo lwesekethe ephambili ye-breaker circuit kunye ne-undervoitage release i-ll, kunye nodidi lofakelo lwezinye iisekethe ezincedisayo kunye neesekethe zokulawula ngu-I;
I-breaker circuit inokumelana nempembelelo ye-airsait sprayoil mistmold kunye nemitha yenyukliya;
Ukuthambekela okuphezulu kofakelo lwe-circuit breaker yi-±22.5 °;
I-breaker circuit inokusebenza ngokuthembekileyo phantsi kwemeko yenyikima (4g);
I-breaker sekethe kufuneka ifakwe kwindawo apho kungekho ngozi yokudubula, akukho luthuli oluqhubayo, akukho ukubola kwentsimbi kwaye akukho monakalo kwi-insulation;
I-breaker circuit kufuneka ifakwe kwindawo engenamvula kunye nekhephu.

Ulwahlulo lwabaphuli beesekethe
Uhlobo A: Akukho kukhutshwa kwe-overcurrent efakwe kwi-N pole, kwaye i-Npole ihlala iqhagamshelwe, kwaye ayivali kwaye ivule nezinye iipali ezintathu.
Uhlobo B: Akukho kukhutshwa okugqithisiweyo kufakwe kwi-N pole, kwaye i-N pole iyavalwa kwaye ivulwe kunye nezinye iipali ezintathu (i-N pole ivalwa kuqala ize ivulwe).
Uhlobo C: Ipali ye-N ixhotyiswe ngokukhulula okungaphaya, kwaye ke ipali iyavalwa kwaye ivulwe kunye nezinye iipali ezintathu (i-N pole ivalwa kuqala ize ivulwe). ,kwaye i-N pole isoloko iqhagamshelwe, kwaye ayivali kwaye ivuleke ngezinye iipali ezintathu.

Ngokwereyithingi yangoku (A)
I-MLM1-63is(6),10,16,20,25,32,40,50,63A amanqanaba alithoba(6Ukucaciswa ngaphandle kokhuseleko lomthwalo);MLM1-125 s(10),16,20,25,32,40,50, 63,80,100,125A level elever;
MLM1-250is100,125,140,160,180,200,225,250A amanqanaba asibhozo;MLM1-400 yi-225,250,315,350,400A amanqanaba amahlanu;
I-MLM1-630 inamanqanaba amathathu e-400,500, kunye ne-630A; i-MLM1-800 inamanqanaba amathathu e-630,700, kunye ne-800A.[Nge() akukhuthazwa ukucaciswa]

Ngokwemowudi yocingo, yahlulwe yaba ziindidi ezine: i-wire-panel wiring, i-back-panel wiring, i-plug-in front-panel wiring, kunye ne-plug-in back-panel wiring.
Ngokohlobo lokukhutshwa ngokugqithisileyo, inokwahlulwa ibe yi-thermal-electromagnetic (complex) uhlobo kunye nohlobo lwe-electromagnetic (ngoko nangoko).
Ngokubhekiselele ekubeni i-breaker circuit ine-accessories.zimbini iintlobo: kunye nezixhobo kunye nangaphandle kwezixhobo:
Iziqhotyoshelwano zihlulwe zibe ziqhotyoshelweyo zangaphakathi kunye neziqhotyoshelo zangaphandle;
Izixhobo zangaphakathi zibandakanya ukukhutshwa kwe-shunt, ukukhutshwa kwe-undervoltage, uqhagamshelwano oluncedisayo, kunye noqhagamshelwano lwe-alamu.Izixhobo zangaphandle ziquka indlela yokusebenza ye-rotary, indlela yokusebenza yombane, i-interlocking structure kunye ne-terminal block yezixhobo ezincedisayo, njl.

Phawula:
1.200: Ibonisa isaphuli sesekethe esinokukhutshwa kombane kuphela; 300: Ibonisa isaphuli sesekethe esinokukhutshwa kwe-thermal-electromagnetic;
2. Kwi-MLM1-125,250 i-four-pole breakers, akukho 240,340,260,360,268,368 xa ipali ye-N iluhlobo A kunye nohlobo D.
3. Kwi-MLM1-400.MLM1-630 kunye ne-MLM1-800, abafowunelwa abancedisayo kwi-248.348.278.kunye ne-378 specication yipere yoqhagamshelwano (oko kukuthi. intloko zizibini ezithathu zoqhagamshelwano (ezithathu ziqhele ukuvulwa kwaye ezintathu ziqhele ukuvalwa).
Iinkcukacha eziphawulwe ngazo zinokubonelela ngeeseti ezimbini zoqhagamshelwano oluncedisayo (ngaphandle kweMLM1-63), kodwa kufuneka zicaciswe xa kuodolwa.
