Intshayelelo
Xai-micro iswitshiXa ivuliwe okanye icinyiwe, "intlantsi yombane" encinci idla ngokuvela phakathi kweziqhagamshelo. Le yi-arc. Nangona incinci, inokuchaphazela ubomi beswitshi kunye nokhuseleko lwezixhobo. Ukuqonda izizathu, iingozi zee-arc, kunye neendlela zokunciphisa ezisebenzayo kubalulekile ekuphuculeni ukuthembeka kwee-micro iiswitshi.
Isizukulwana see-Arcs: "I-Small Spark" Xa i-Current iphazamiseka
Xa oonxibelelwano be-micro Ukuba iswitshi ivuliwe okanye ivaliwe, utshintsho olukhawulezileyo kumbane lunokubangela ukuba umoya ophakathi kweziqhagamshelo ube yi-ionized, nto leyo evelisa i-arc. Kufana nombane ngemini yemvula, kodwa ngomlinganiselo omncinci kakhulu. Le nto icaca ngakumbi xa iswitshi isetyenziselwa ukulawula izixhobo ezinemithwalo, ezifana neemoto okanye iibhalbhu zokukhanya. Okukhona umbane umkhulu kwaye i-voltage iphezulu, kokukhona kunokwenzeka ukuba i-arc yenzeke. I-spark ebonwayo ngamaxesha athile xa ucinezela iswitshi yasekhaya ngumzekelo wale arc.
Iingozi zeArcs: "Umbulali Othuleyo" Ogutyula iiSwitshi
Ii-arcs zishushu kakhulu kwaye zinokutshabalalisa kancinci kancinci umphezulu wee-contacts, nto leyo ebangela ukuba zingalingani. Ekuhambeni kwexesha, oku kunokukhokelela ekudibaneni kakubi, apho iswitshi ingaphenduli xa icinezelwe okanye isignali ingenamsebenzi. Umzekelo, xa amaqhosha kwimawusi eyeka ukusebenza emva kokusetyenziswa ixesha elide, oku kubangelwa kukuba ii-contacts zidilizwa zii-arcs. Kwiimeko ezinzima, ii-arcs zinokubangela ukuba ii-contacts zinamathelene, zithintele iswitshi ukuba icime kwaye zibeke umngcipheko wokusebenza rhoqo kwezixhobo, ngakumbi kwimishini yemizi-mveliso kunye neesekethe zeemoto, apho iimpazamo ezinjalo zinokukhokelela kwiingozi zokhuseleko.
Iindlela zokuCima: Ukongeza "iShield" kwiSwitch
Ukuze kuliwe nee-arcs, eli shishini liphuhlise iindlela ezininzi ezisebenzayo. Ii-RC buffer circuits, ezenziwe zii-resistors kunye nee-capacitors, zisebenza njenge-"buffer pad" ngokufunxa amandla aveliswa zii-arcs, njenge-speed bump yotshintsho lwangoku, ukunciphisa amandla ee-sparks. Ii-Varistors zisebenza "njengabagcini-masango," zihlala zingasebenzi phantsi kwe-voltage eqhelekileyo kodwa ziqhuba ngokukhawuleza xa i-arc ibangela ukunyuka kwe-voltage ngequbuliso, zijika umbane ogqithisileyo kwaye zikhusele oonxibelelwano. Ii-Solid-state relay, ezisebenzisa izinto ze-elektroniki ukulawula umbane ngaphandle koqhagamshelwano loomatshini, ngokusisiseko zisusa amathuba okuba nee-arcs kwaye zihlala zisetyenziswa kwizixhobo zonyango ezichanekileyo kunye nezixhobo.
Isiphelo
Ezi ndlela zokucinezela zenza i-micro Iiswitshi zihlala ixesha elide kwaye zithembekile. Ukunciphisa impembelelo yee-arcs kunokunciphisa amathuba okuba kubekho iimpazamo kwaye kwandise ubomi bezixhobo zasekhaya kunye nezixhobo zoshishino. Ngokuhambela phambili kwetekhnoloji, "amandla okutshabalalisa" ee-arcs ahlala ebuthathaka, okuvumela ukuba ii-micro-micro zisebenze. iiswitshi ukuze zisebenze ngokuzinzileyo kwiimeko ezininzi kwaye zikhusele ngokuzolileyo ukusebenza kwesiqhelo kwezixhobo.
