U-Liper, umhlinzeki oholayo wezixazululo zokukhanyisa ezintsha, namuhla ugcizelela isidingo esibalulekile sokuvikelwa kokuhlinzwa kuzo zombili izinhlelo zokukhanyisa zokuhlala nezokuhweba. Ukwenyuka kwamandla, ngokuvamile okungaqondwa kahle, kubangela usongo olukhulu ekuphileni isikhathi eside nokusebenza kokukhanya kwesimanje.
Kuyini Ukuhlinza Amandla?
Ukuphakama kwamandla ukukhuphuka okungazelelwe, okufushane ku-voltage kagesi okudlula kude ukugeleza okujwayelekile (isb., 100V/240V AC). Lezi zici, ezithatha izigidi zesekhondi, zingasuka ku:
1.Umbani: Amahithi aqondile noma iziteleka eziseduze eziheha ukwanda kwezintambo zamandla.
2.Ukusebenza Kwegridi: Ukushintsha kwezinsiza, ukwenziwa kusebenze kwebhange le-capacitor, noma ukusula amaphutha.
3.Imithombo Yangaphakathi: Amamotho amakhulu (amakheshi, umshini kagesi) agibela/avaliwe ngaphakathi kwebhilidi.
Usongo Olufihliwe Ekukhanyeni Kwakho
Ukwenyuka kubangela umonakalo oyinhlekelele noma okhulayo:
1.Ukwehluleka Okusheshayo: Ukutubeka okungazelelwe kwezishayeli ze-LED, izilawuli, noma izinsiza zikagesi.
2.Ukusebenza Kwehlisiwe: Ukulimala kancane kancane kwenza ubude bempilo bube bufushane, okubangela ukucwayiza, ukushintsha kombala, noma ukunciphisa ukukhanya.
3.Lawula Ukonakala Kwesistimu: Amanethiwekhi okukhanyisa ahlakaniphile akhubazayo, izinzwa, namasistimu wokufiphalisa.
4.Izingozi Zokuphepha: Izingozi zomlilo ezingaba khona ezivela ezingxenyeni ezilimele.
5.Isikhathi Sokuphumula Esibizayo Nokushintsha: Izindleko zokulungisa nokulungisa izinto ezingahleliwe.
Ngemva kokufunda lolu lwazi, mhlawumbe uyazibuza ukuthi ungazigwema kanjani lezi zinkinga...Futhi empeleni, I-International Electrotechnical Commission (IEC) ibeka amabhentshimakhi acacile wokuvikeleka kokuhlinzwa ezimpahleni zokukhanyisa ngokusebenzisaI-IEC 60598-1kanye namazinga athile okusebenza afanaI-IEC 61547. Izidingo ezibalulekile zifaka:
1.Izibani zasendlini: Ngokuvamile kuyadingeka ukuze umelane nokunyuka kweLeveli 2 (okuvamile emabhilidini):
·Umugqa-kuya-Ulayini:1 kV
·Ulayini-kuya-Emhlabeni (Ephansi): 2 kV
2.Izibani zangaphandle: Ichayeke ezingozini eziphakeme (umbani, ukugijima kwekhebula elide), edinga ukungatheleleki kweLeveli 3 noma 4:
·Ulayini ukuya kuLayini: 2 kV noma 4 kV
·I-Line-to-Earth (Ground):4 kV noma 6 kV – Ibalulekile ekufakweni kwezigxobo, amapherimitha esakhiwo, noma indawo.
Wenzani uLiper ukuze aqinisekise ukuthi izibani zingaphepha futhi zibe nokuphila isikhathi eside?
U-Liper uyakukhathalela ukuphepha ngaso sonke isikhathi, ngakho onjiniyela bethu bagxila ekwengezeni izisetshenziswa zokuvikela ukuhlinza futhi osolwazi bethu bazohlola izibani zethu egumbini lokuhlola le-EMC ukuze baqinisekise ukuthi izibani zethu zinezinga eliphezulu lezinga lokuhlinzwa.
1.Yengeza okunyeamadivaysi okuvikela ukukhuphukangenkathi wenza ibhodi le-PCB.
·Ama-Varistors: I-clamp voltage ngokuphambukisa amandla akhona.
·Fuse resistor: vuthela ngokushesha ukuze uvimbele izehlakalo zokuphepha ezibucayi (ezifana nemililo).
·I-Transient Voltage Suppression (TVS): impendulo eshesha kakhulu, ivikela ama-IC azwelayo kubashayeli/izilawuli. Ukuphatha amandla aphansi.
·Ama-inductors emodi evamile: yenza i-current ingakwazi ukukhuphuka ngokuzumayo kodwa ikhule kancane futhi imunce amandla angazelelwe.(kudingeka ku-streetlight, ama-floodlights namalambu aphezulu)
(ngaphambi kokusebenzisa i-inductor yemodi evamile)
(ngemuva kokusebenzisa i-inductor yemodi evamile)
2.Hlola izibani elabhorethri yethu yobungcweti
·Ijeneretha yokuhlinza: izinga lokuhlolwa liphezulu kunezinga le-IEC. Ezibani zasemgwaqweni, singafinyelela ku-10kV ngemva kokwengeza izinto ezivimbela umbani.
·Igumbi lokuhlola le-EMC: hlola amandla okumelana nokuphazamiseka futhi uhlole ukuthi izibani zethu zizoba nomthelela yini kwezinye izinto zikagesi noma cha. Lokhu kuhlolwa kungaphansi kwezinga le-CB.
Ngemuva kwalezi zenzo, ungathembela ukusebenzisa izibani zethu kuphrojekthi! I-Liper, uphawu ongalethemba kuze kube phakade!
