I-Liper, umboneleli ophambili wezisombululo zokukhanyisa ezintsha, namhlanje ugxininisa imfuneko ebalulekileyo yokukhusela ukugqabhuka kombane kwiinkqubo zokukhanyisa zasemakhaya nezamashishini. Ukugqabhuka kombane, okuhlala kungaqondwa kakuhle, kuyingozi enkulu kwixesha elide kunye nokusebenza kokukhanya kwanamhlanje.
Yintoni iPower Surge?
Ukunyuka kwamandla kukunyuka ngequbuliso, okufutshane kwi-voltage yombane edlula kakhulu ukuhamba okuqhelekileyo (umz., i-100V/240V AC). Ezi spikes, ezihlala ixesha elide kwisigidi sesekhondi, zinokuvela kwi:
1.Ukubetha kombane: Ukubetha ngqo okanye ukubetha okukufutshane okubangela ukugqobhoza kwiintambo zombane.
2.Imisebenzi yeGridi: Ukutshintsha izixhobo zokusebenza, ukusebenza kwe-capacitor bank, okanye ukucoca iimpazamo.
3.Imithombo YangaphakathiIimoto ezinkulu (ii-lifti, umatshini wombane) eziqhuba/zicima ngaphakathi kwisakhiwo.
Ingozi Efihlakeleyo Kwizibane Zakho
Ukwanda kwamanzi kubangela umonakalo omkhulu okanye oqokelelweyo:
1.Ukusilela Kwangoko: Ukutsha ngequbuliso kwabaqhubi be-LED, abalawuli, okanye izixhobo zombane.
2.Ukusebenza okuphantsi: Umonakalo ohamba kancinci kancinci onciphisa ubomi, obangela ukufiphala, ukutshintsha kombala, okanye ukukhanya okunciphileyo.
3.Umonakalo weNkqubo yoLawulo: Iinethiwekhi zokukhanyisa ezikrelekrele, izinzwa, kunye neenkqubo zokufiphalisa ukukhanya.
4.Iingozi zoKhuseleko: Iingozi zomlilo ezinokubakho ezivela kwizinto ezonakeleyo.
5.Ixesha lokuphumla elibizayo kunye nokutshintshwa kwezinto: Iindleko zokulungisa ezingacwangciswanga kunye nokutshintshwa kwezinto.
Emva kokufunda olu lwazi, mhlawumbi uyazibuza ukuba ungaziphepha njani ezi ngxaki... Kwaye eneneni, i-International Electrotechnical Commission (IEC) ibeka imilinganiselo ecacileyo yokumelana nokuvuza kwezibane ngokusebenzisaI-IEC 60598-1kunye nemigangatho ethile yokusebenza efanaI-IEC 61547Iimfuno eziphambili ziquka:
1.Izibane zangaphakathi: Idla ngokufuneka ukuze imelane nokunyuka kweNqanaba lesi-2 (okuqhelekileyo kwizakhiwo):
·Umgca ukuya kumgca:1 kV
·Umgca ukuya eMhlabeni (Emhlabeni): 2 kV
2.Izibane Zangaphandle: Ichatshazelwe kwiingozi eziphezulu (umbane, ukuhamba ngentambo ixesha elide), ifuna ukhuseleko lweNqanaba lesi-3 okanye lesi-4:
·Umgca ukuya kumgca: 2 kV okanye 4 kV
·Umgca ukuya eMhlabeni (Emhlabeni):4 kV okanye 6 kV – Kubalulekile kwizinto ezifakelweyo kwiipali, imida yesakhiwo, okanye iindawo ezijonge umhlaba.
Yintoni eyenziwa yiLiper ukuqinisekisa ukuba izibane zikhuselekile kwaye zihlala ixesha elide?
ULiper ukhathalela ukhuseleko ngalo lonke ixesha, ngoko ke iinjineli zethu zigxila ekongezeni izixhobo zokukhusela ukugqobhoza kwaye oonjingalwazi bethu baya kuvavanya izibane zethu kwigumbi lovavanyo lwe-EMC ukuqinisekisa ukuba izibane zethu zinomgangatho ophezulu wokugqobhoza.
1. Yongeza ezinyeizixhobo zokukhusela ukugalelekangelixa esenza ibhodi yePCB.
·IiVaristors: i-clamp voltage ngokujika i-surge current.
·Isithinteli sefusi: vuthela ngokukhawuleza ukuthintela iziganeko zokhuseleko ezinzulu (ezifana nemililo).
·Ucinezelo lweVolthi oluThutyana (iiTVS): impendulo ekhawulezayo kakhulu, ikhusela ii-IC ezinobuthathaka kubaqhubi/abalawuli. Ulawulo oluphantsi lwamandla.
·Ii-inductors zemodi eqhelekileyo: ukwenza umsinga awukwazi ukunyuka ngequbuliso kodwa ukwandisa kancinci kwaye ufunxe amandla ngequbuliso. (iyimfuneko kwizibane zasesitalatweni, izibane ezikhanyayo kunye nezibane ze-highbay)
(ngaphambi kokusebenzisa i-common mode inductor)
(emva kokusebenzisa i-common mode inductor)
2.Vavanya izibane kwilebhu yethu yobungcali
·Umatshini wokuvelisa umbane: umgangatho wovavanyo uphezulu kunomgangatho we-IEC. Kwizibane zasezitalatweni, singafikelela kwi-10kV emva kokongeza izinto zokuthintela umbane.
·Igumbi lovavanyo lwe-EMC: vavanya amandla okulwa nokuphazamiseka kwaye uvavanye ukuba izibane zethu ziya kuba nefuthe na kwezinye izixhobo okanye akunjalo. Olu vavanyo luphantsi komgangatho we-CB.
Emva kwezi zenzo, ungathemba ukusebenzisa izibane zethu kule projekthi! I-Liper, uphawu onokuluthemba ngonaphakade!
