Injongo ephambili
I-fuse ilungele ukulayishwa komgca kunye nokukhusela i-short-circuit kwisixhobo sokusasazwa kwezixhobo zombane ze-industrial kunye ne-AC ye-AC rated frequency ye-50Hz, i-voltage elinganisiweyo ye-AC ukuya kwi-690V, i-DC 250V ukuya kwi-440V kunye ne-cunent elinganiselwe kwi-1250A.
1.2Uhlobo kunye neenkcukacha
Uhlobo kunye neenkcukacha
I-Fuse yohlulwe ngokweesayizi ezintandathu ngokobungakanani betyhubhu yefuse.Isayizi nganye inoluhlu oluhambelanayo lwangoku.Jonga kwiiparamitha eziphambili zobuchule bomgangatho we-cun ent wefuse yobukhulu obahlukeneyo.I-fuse inokuxhotyiswa nge-impactor ngokweemfuno zomsebenzisi, kwaye i- impactor ibekwe ngokubanzi phezu koqhagamshelwano lwe-fuse.
I-nomenclature ye-fuses
Iimeko eziqhelekileyo zokusebenza
◆ Ubushushu bomoya okwindawo yokuhlala
Iqondo lokushisa lomoya we-ambient aliyi kudlula i-40 ° C, ixabiso eliqhelekileyo elilinganiswe kwiiyure ezingama-24 aliyi kudlula i-35 C, kwaye ixabiso eliqhelekileyo elilinganiswe ngonyaka omnye liya kuba ngaphantsi kweli xabiso.
Ubuncinane bomoya we-ambient yi-5 C.
◆Ukuphakama
Umphakamo wendawo yofakelo awuyi kudlula i-2000m.
◆Iimeko ze-atmospheric
Ukufuma kwayo okunxulumeneyo akufunekanga kudlule kwi-50% kobona bushushu buphezulu be-40°C
Ukufuma okungaphezulu kunokufumaneka kwiqondo lobushushu elisezantsi, umzekelo, ukuya kuthi ga kwi-90% kwi-20C.
Ngaphantsi kwezi meko, ukunyuswa okuphakathi kungenzeka ngengozi ngenxa yokutshintsha kweqondo lokushisa.Ngaphandle kokubonisana nomenzi, i-fuse ayinakufakwa kwindawo enenkungu yetyuwa okanye idiphozithi engaqhelekanga yoshishino.
◆I-Voltage
Awona mandla ombane aphezulu enkqubo akayi kuba ngaphezu kwe-1 10% yombane olinganisiweyo we-fuse.
Kwi-fuse enevoltheji elinganisiweyo ye-voltage ye-690V AC kunye ne-250V 1440V DC, umbane ophezulu wenkqubo awuyi kudlula i-105% yombane olinganisiweyo we-fuse.
Iimeko zofakelo eziqhelekileyo
◆Icandelo lofakelo
Udidi lofakelo lwefuse ludidi I.
◆Inqanaba longcoliseko
Iqondo lokuchasa ungcoliseko lwefuse aliyi kuba ngaphantsi kwenqanaba3.
◆Imo yokufakela
I-fuse inokufakwa ngokuthe nkqo, ngokuthe tye okanye ngokutyibilikayo kwindawo yokusebenza ngaphandle kokungcangcazela okubalulekileyo kunye nefuthe lokungcangcazela.
Uluhlu lokuqhawula kunye nokusetyenziswa
Ikhonkco le-fuse likhonkco le-fuse elinenjongo ngokubanzi kunye noluhlu olupheleleyo lokuqhawula umthamo, okt "gG" ikhonkco ye-fuse.
Iimpawu zesakhiwo kunye nomgaqo wokusebenza
I-fuse inesiseko se-fuse kunye nekhonkco ye-fuse.Isiseko se-fuse siqulunqwe ngoqhagamshelwano olusisiseko, i-base plate, njl.
Xa i-fuse ifakwe kwisekethe, xa i-current idlula kwi-fuse idlula ixabiso elithile ixesha elaneleyo, ukunyibilika kumzimba we-fuse kuya kuxutywa, kwaye i-arc yenziwe xa i-fuse ixutywa ngesanti ye-quartz kwi-fuse. ityhubhu iya kucinywa, ukuze kufezekiswe injongo yokuphula isiphaluka.
Xa i-melt ivuthelwa, isalathisi kwikhonkco ye-fuse iya kuvela, ebonisa ukuba ikhonkco ye-fuse ivuthelwe.
Kwi-fuse exhotywe nge-impactor, xa i-melt ixutywe, impembelelo iya kuphuma ngokuzenzekelayo.Umsebenzisi ufuna kuphela ukufaka i-micro-switch okanye isixhobo esifanelekileyo sokuthumela isignali (ekhethiweyo kwaye ithengwe ngumsebenzisi) phambi kwempembelelo, kwaye emva koko isignali efunekayo inokufumaneka emva kokuba i-fuse ixutywe.

5. Ukufakwa, ukusetyenziswa kunye nokugcinwa kwe-fuse
I-fuse iya kufakwa ngaphakathi okanye kwikhabhinethi engayi kuchaphazeleka yimvula kunye nekhephu, kwaye ayiyi kubonakaliswa kwaye ifakwe kwindawo ekulula ukuyibamba.Xa ufaka i-fuse, qinisekisa ukuba ukukhutshwa kombane kukhulu kune-8 mm kwaye umgama we-creepage mkhulu kune-10 mm. Kwisekethe, indawo enqamlezayo yocingo lokudibanisa inconywa njengexabiso kwiThebhile 4.
Itheyibhile yesi-4 indawo yecandelo lokudibanisa ucingo lwe-fuse
Umzekelo | I-Fuse rated okwangoku A | Indawo yecandelo locingo lokudibanisa 9 mm |
NT-000 | 100 | 35 |
NT-00 | 160 | 70 |
NT-1 | 250 | 120 |
NT-2 | 400 | 240 |
NT-3 | 630 | 2X (40X5) |
NT-4 | 1250 | 2X (60X5) |
Xa ikhonkco le-fuse livuthelwa, ikhonkco entsha ye-fuse enemodeli efanayo, ubungakanani kunye nomlinganiselo wangoku njengekhonkco lokuqala le-fuse kufuneka itshintshwe endaweni yocingo lobhedu.
Ukutshintshwa kwamakhonkco e-fuse kuya kwenziwa ngabachwephesha abasebenzisa abathwali be-fuse abakhethekileyo.
Xa utshintsha ikhonkco ye-fuse, kufuneka iqhutywe phantsi kwemeko yokungabikho komthwalo, ngokukhethekileyo xa ukunikezelwa kwamandla kunqunyulwa.Akuvumelekanga ngokupheleleyo ukusebenzisa i-fuse ukunqumla okanye ukudibanisa umthwalo xa utshintshi lusetyenziswa.Emva kokutshintsha ikhonkco le-fuse, qinisekisa ukuba uqhagamshelwano phakathi kwekhonkco ye-fuse kunye noqhagamshelwano olusisiseko lunxibelelana kakuhle.
Xa ucima umbane kunye nokutshintsha ikhonkco ye-fuse, nceda ususe uthuli kunye nolunye ukungcola kwisiseko se-fuse, ngokukodwa uqhagamshelwano lwesiseko, ukwenzela ukuba i-fuse isebenze kakuhle.
Ngexesha lokusebenza, isalathisi sekhonkco ye-fuse iya kujongwa rhoqo ukuze kufunyanwe isigaba esinye okanye isigaba esilahlekileyo ngexesha.
Ukuthutha kunye nokugcinwa kwe-fuse
I-fuse iya kukhuselwa emvuleni nakwikhephu ngexesha lokuthuthwa nokugcinwa.Umphakamo okhululekileyo webhokisi yonke awuyi kuba mkhulu kune-250mm.
I-fuses iya kugcinwa kwindawo yokujikeleza komoya kunye nendawo eyomileyo, kwaye ukuphakama kwe-stacking akuyi kudlula imigangatho emithandathu.
Ukukhutshwa kunye nokuhlolwa kwe-fuse
Emva kokukhulula, jonga kuqala ukuba i-nameplate ye-fuse iyahambelana noluhlu lokupakisha kunye nophawu kwibhokisi yokupakisha, emva koko khangela ukuba i-fastener kwisiseko se-fuse okanye ikhonkco ye-fuse ikhululekile okanye iyawa o比 khangela ukuba ityhubhu ye-porcelain Ikhonkco le-fuse liqhekekile okanye liqhekekile, khangela ukuba isanti ye-quartz kwibhloko ye-fuse iyaphuma, kwaye khangela ukuba i-fuse ifakwe okanye ihlaselwe ngamanzi.Ukuba le miqathango ingentla ifunyenwe, i-fuse ayinakusetyenziswa, kwaye umenzi uya kuqhagamshelwa ngexesha.
Ibhokisi ye-fuse iya kuba nesatifikethi semveliso, uluhlu lokupakisha kunye nomyalelo wokusebenza.
Imiyalelo yokuodola
Xa u-odola iifusi, imodeli, iinkcukacha, ubungakanani kunye nebakala langoku lekhonkco le-fuse elihambelanayo liya kuboniswa.Isiseko se-fuse kunye nekhonkco ye-fuse inokuodolwa ngokwahlukileyo.
Kwii-fuses zeenkcukacha ezikhethekileyo kunye namanqanaba angoku, umenzi uya kuboniswa xa u-odola.
