Xa kukhethwa usasazo lwamandla kwimizi-mveliso, iifusi zihlala zithathwa njengeendawo ezilula zokuncedisa. Iinjineli ezininzi kunye nabasebenzi bokuthenga baneengxaki ezinzulu zokungaqondani:Xa ukhetha i-industrial fuse, ukuthelekisa umbane olinganisiweyo nomthwalo kwanele. Bayityeshela nje kancinci i-voltage elinganisiweyo, abayinaki into yokuba amandla ombane aphukile, kwaye bade bayityeshele nemigangatho yokusebenza. Olu khetho lungenankathalo aluyi kubangela kuphela ukutsha kwezixhobo kunye nokuvalwa rhoqo kwenkqubo kwiimeko ezincinci kodwa lukwabangela ukufiphaza kwe-arc, ukuqhuma kwekhabhathi, umlilo kunye nezinye iingozi zokhuseleko kwiimeko ezinzima.
Namhlanje, siza kuthathaI-People Electric RDT16(NT0) Series Knife Blade Fusenjengemeko esebenzayo yokuchasa ngokupheleleyo umbono ongalunganga "wokwanela ngombane ohambelanayo kuphela". Siza kuchaza eyona nto iphambili yokukhetha i-fuse yemizi-mveliso: umbane olinganisiweyo yimfuneko esisiseko kuphela; umthamo wokuphuka ngumgca obomvu wokhuseleko; ukuthotyelwa kwe-IEC60269-2 yeyona nto iphambili yomgangatho, kwaye iimpawu zokhuseleko zibalulekile kwisiqinisekiso sokusebenza.
1. Ingcamango Ephosakeleyo Ebulalayo: Ukugxila Kuphela Kwimingxunya Yangoku Elinganisiweyo Iingozi Ezifihliweyo Zeenkqubo Zokusasazwa
Uninzi lwabantu lucinga ukuba i-fuse isebenza kuphela xa i-overcurrent inqunyulwa, kwaye inokukhusela isekethe logama nje i-current yayo elinganisiweyo ihambelana nezixhobo okanye umthwalo wesekethe. Olu lwazi luchanekile kwisithathu esinye kuphela. Isibini kwisithathu esisele seeparameter eziphambili asihoywa, eziyimbangela yeengozi ezininzi zombane.
⭕️Iziphumo Ezintathu Ezinzima Zokujonga Kuphela Uvavanyo Lwangoku LweFuse
1.Ukungaphumeleli ngokupheleleyo koKhuseleko lweSijikelezo esifutshane
Umsinga we-short-circuit kwiindawo zoshishino unokufikelela ngokulula kumashumi amawaka ukuya kumakhulu amawaka ee-ampere. Ukuba amandla okuqhekeza i-fuse awanelanga, i-fuse ayinakuyinqumla ngokukhuselekileyo i-fault current. Ayiyi kuyicima i-arc yangaphakathi, nto leyo ekhokelela ekuqhekekeni kwegobolondo, ukuvuza kwe-arc, kunye nokutsha kweentambo ezijikelezileyo kunye nezixhobo, nto leyo ebangela iintlekele zesibini.
