I-Liper, umboneleli okhokelayo wezisombululo zokukhanyisa ezitsha, namhlanje ugxininisa imfuneko ebalulekileyo yokukhusela i-surgery kuzo zombini iinkqubo zokukhanyisa zokuhlala kunye nezorhwebo. Ukunyuka kwamandla, okuhlala kungaqondwa kakuhle, kubangela ingozi enkulu kubomi obude kunye nokusebenza kwezibane zanamhlanje.
Yintoni i-Power Surge?
Ukunyuka kombane kukunyuka okukhawulezileyo, okwethutyana kumbane wombane ogqithise kakhulu ukuhamba okusemgangathweni (umzekelo, i-100V/240V AC). Ezi spikes, ezihlala kwizigidi zesekondi, zinokusuka ku:
1.Imibane: Ukubethelwa ngokuthe ngqo okanye ugwayimbo olukufutshane lukhuthaza ukunyuka kwiintambo zamandla.
2.ImiSebenzi yegridi: Ukutshintshwa kwezinto eziluncedo, ukusetyenziswa kwebhanki ye-capacitor, okanye ukucoca impazamo.
3.Imithombo yangaphakathi: Iinjini ezinkulu (izinyusi, umatshini wombane) zihamba ngebhayisekile/zivaliwe ngaphakathi kwesakhiwo.
Isisongelo esifihliweyo kwisibane sakho
Ukunyuka kubangela intlekele okanye umonakalo okhulayo:
1.Ukusilela kwangoko: Ukutshiswa ngokukhawuleza kwabaqhubi be-LED, abalawuli, okanye izixhobo zombane.
2.Ukuthotywa koMsebenzi: Umonakalo ohamba kancinci wenza bufutshane ubomi, kubangela ukuqhwanyaza, ukutshintsha kombala, okanye ukunciphisa ukukhanya.
3.Ulawulo Lomonakalo Wenkqubo: Ikhubaza uthungelwano lokukhanyisa olukrelekrele, izivamvo, kunye neenkqubo zobumnyama.
4.Iingozi zoKhuseleko: Imingcipheko yomlilo enokubakho kumalungu awonakeleyo.
5.Iindleko zokuPhuhlisa kunye noTshintsho: Ugcino olungacwangciswanga kunye neendleko zokutshintsha izinto.
Emva kokufunda olu lwazi, mhlawumbi uyazibuza ukuba ungayiphepha njani le miba...Kwaye enyanisweni, IKhomishini yezoMbane yeHlabathi (i-IEC) ibeka ibhenchmarks ezicacileyo zokugonyeka kombane kwizibane zokukhanyisa.IEC 60598-1kunye nemigangatho ethile yokusebenza efanaIEC 61547. Iimfuno eziphambili ziquka:
1.Izibane zangaphakathi: Ngokwesiqhelo kufuneka umelane nokunyuka kweNqanaba lesi-2 (ixhaphakile kwizakhiwo):
·Umgca-kuMgca:1 kV
·Umgca ukuya kuMhlaba (Umhlaba): 2 kV
2.Izibane zangaphandle: Ivezwe kwimingcipheko ephezulu (umbane, ukubaleka kwentambo ende), efuna iNqanaba lesi-3 okanye le-4 lokungakhuseleki:
·Umgca kumgca: 2 kV okanye 4 kV
·Umgca ukuya kuMhlaba (Umhlaba):4 kV okanye i-6 kV – Ibalulekile kwizithintelo kwiipali, iiperimitha zesakhiwo, okanye imbonakalo-mhlaba.
Wenza ntoni uLiper ukuqinisekisa ukuba izibane zinokukhuseleka kunye nobomi obude?
I-Liper ikhathalele ukhuseleko ngalo lonke ixesha, ngoko ke iinjineli zethu zijolise ekongezeni izixhobo zokhuselo lotyando kwaye oonjingalwazi bethu baya kuvavanya izibane zethu kwigumbi lovavanyo lwe-EMC ukuqinisekisa ukuba izibane zethu zinenqanaba eliphezulu lotyando.
1.Yongeza ezinyeizixhobo zokukhusela isantyangelixa usenza ibhodi yePCB.
·Varistors: i-clamp voltage ngokuphambukisa amandla akhoyo.
·Fuse resistor: vuthela ngokukhawuleza ukuthintela izehlo ezinobuzaza zokhuseleko (ezifana nemililo).
·Uxinzelelo lwamandla ombane oThutyanayo (TVS): impendulo ekhawulezayo kakhulu, ikhusela ii-ICs ezinovakalelo kubaqhubi/abalawuli. Ukuphathwa kwamandla aphantsi.
·Ii-inductors zendlela eqhelekileyo: yenza umsinga unganyukeli ngesiquphe kodwa wonyuke kancinane kwaye ufunxe amandla ngesiquphe.

(emva kokusebenzisa i-inductor yendlela eqhelekileyo)
2.Vavanya izibane kwilabhoratri yethu yobungcali
·Surge generator: umgangatho wovavanyo uphezulu kunomgangatho we-IEC. Kwizibane zasezitalatweni, sinokufikelela kwi-10kV emva kokongeza izithinteli zombane.
·Igumbi lovavanyo lwe-EMC: Vavanya amandla okuthintela ukuphazamiseka kwaye uvavanye ukuba izibane zethu ziya kuba nefuthe kwesinye isixhobo okanye hayi. Olu vavanyo luphantsi komgangatho we-CB.
Emva kwezi zenzo, unokuthembela ekusebenziseni izibane zethu kwiprojekthi! I-Liper, uphawu onokuthi uluthembe ngonaphakade!
