I-Liper, umhlinzeki ohamba phambili wezixazululo zokukhanyisa ezintsha, namuhla igcizelela isidingo esibalulekile sokuvikelwa kokukhuphuka kwamandla kuzo zombili izinhlelo zokukhanyisa zasemakhaya nezebhizinisi. Ukukhuphuka kwamandla, okuvame ukungaqondwa kahle, kuyisongo esikhulu ekudeleni nasekusebenzeni kokukhanya kwesimanje.
Kuyini Ukunyuka Kwamandla?
Ukwanda kwamandla kungukunyuka okusheshayo, okufushane kwamandla kagesi okudlula kakhulu ukugeleza okujwayelekile (isb., 100V/240V AC). Lokhu kuphakama, okuhlala isikhathi esiyizigidi zomzuzwana, kungavela ku:
1.Ukushaya Kombani: Ukushaya okuqondile noma ukushaya okuseduze okubangela ukukhuphuka kwezintambo zikagesi.
2.Ukusebenza kwegridi: Ukushintsha izinsiza, ukusebenza kwe-capacitor bank, noma ukuhlanza amaphutha.
3.Imithombo Yangaphakathi: Ama-motor amakhulu (ama-lifti, umshini kagesi) ahamba ngebhayisikili ngaphakathi kwesakhiwo.
Usongo Olufihliwe Ekukhanyeni Kwakho
Ukwanda kwezifo kubangela umonakalo omkhulu noma oqongelelekayo:
1.Ukwehluleka Okusheshayo: Ukusha okungazelelwe kwabashayeli be-LED, abalawuli, noma izinsiza zikagesi.
2.Ukusebenza Okuphansi: Umonakalo ohamba kancane kancane onciphisa isikhathi sokuphila, okubangela ukucwazimula, ukushintsha kombala, noma ukwehla kokukhanya.
3.Umonakalo Wesistimu Yokulawula: Amanethiwekhi okukhanyisa ahlakaniphile, izinzwa, kanye nezinhlelo zokufiphaza ezikhubazayo.
4.Izingozi Zokuphepha: Izingozi zomlilo ezingaba khona ezivela ezingxenyeni ezonakele.
5.Isikhathi Sokuphumula Esibizayo Nokushintsha: Izindleko zokulungisa ezingahleliwe kanye nokushintsha izinto.
Ngemva kokufunda lolu lwazi, mhlawumbe uyazibuza ukuthi ungazigwema kanjani lezi zinkinga...Eqinisweni, i-International Electrotechnical Commission (IEC) ibeka izilinganiso ezicacile zokuzivikela ekukhuphukeni kwezibani ngokusebenzisaI-IEC 60598-1kanye nezindinganiso zokusebenza ezithile ezifanaI-IEC 61547Izidingo ezibalulekile zifaka:
1.Izibani zangaphakathi: Ngokuvamile kuyadingeka ukuze kumelwane nokuphakama kwezinga lesi-2 (okuvamile ezakhiweni):
·Umugqa kuya kumugqa: 1 kV
·Umugqa-kuya-Emhlabeni (Phansi): 2 kV
2.Izibani Zangaphandle: Ukuchayeka ezingozini eziphezulu (umbani, ukuhamba kwekhebula isikhathi eside), okudinga ukuzivikela kweLevel 3 noma 4:
·Umugqa nomugqa: 2 kV noma 4 kV
·Umugqa-Ukuya-Emhlabeni (Phansi): 4 kV noma 6 kV – Kubalulekile ezintweni ezifakwe ezinsikeni, emaphethelweni esakhiwo, noma ezindaweni ezizungezile.
Yini eyenziwa yiLiper ukuqinisekisa ukuthi izibani zingaba ziphephile futhi ziphile isikhathi eside?
I-Liper ikhathalela ukuphepha ngaso sonke isikhathi, ngakho onjiniyela bethu bagxila ekufakeni amadivayisi okuvikela ukukhuphuka kwegesi futhi oprofesa bethu bazohlola izibani zethu egumbini lokuhlola le-EMC ukuqinisekisa ukuthi izibani zethu zinezinga eliphakeme lokukhuphuka kwegesi.
1. Engeza okunyeamadivayisi okuvikela ukukhuphukangenkathi kwenziwa ibhodi le-PCB.
·Ama-Varistors: i-clamp voltage ngokuphambukisa i-surge current.
·Isivikelo sefusi: shaya ngokushesha ukuze uvimbele izehlakalo zokuphepha ezingathi sína (njengemililo).
·Ukucindezela I-Voltage Yesikhashana (i-TVS): impendulo eshesha kakhulu, evikela ama-IC abucayi kubashayeli/abalawuli. Ukuphathwa kwamandla aphansi.
·Ama-inductor emodi evamile: ukwenza ugesi awukwazi ukwanda ngokuzumayo kodwa ukwanda kancane futhi umunce amandla angazelelwe. (kuyadingeka ekukhanyeni komgwaqo, izibani ezikhanyayo kanye nezibani zase-highbay)
(ngaphambi kokusebenzisa i-common mode inductor)
(Ngemva kokusebenzisa i-common mode inductor)
2. Hlola izibani elabhorethri yethu yobungcweti
·Ijeneretha yokwanda: izinga lokuhlolwa liphakeme kunezinga le-IEC. Ezibanini zasemgwaqweni, singafinyelela ku-10kV ngemuva kokufaka izibambi zombani.
·Igumbi lokuhlola le-EMC: hlola amandla okuvimbela ukuphazamiseka bese uhlola ukuthi izibani zethu zizothinta yini ezinye izinto zokusebenza noma cha. Lokhu kuhlola kungaphansi kwezindinganiso ze-CB.
Ngemva kwalezi zenzo, ungathemba ukusebenzisa izibani zethu kuphrojekthi! I-Liper, uhlobo ongaluthemba kuze kube phakade!
Isikhathi sokuthunyelwe: Juni-17-2025
