M'chilimwe, mabingu amachitika kawirikawiri, kugunda kwa mphezi kumakhala kutulutsa kwamagetsi komwe nthawi zambiri kumatumiza ma volt mamiliyoni ambiri kuchokera kumtambo kupita pansi kapena mtambo wina.Ikayenda, mphezi imapanga mphamvu yamagetsi yamagetsi mumlengalenga yomwe imapanga masauzande a ma volts (otchedwa ma surges) pazingwe zamagetsi komanso mafunde omwe amapangidwa pamtunda wamakilomita mazanamazana.Kuukira kosalunjika kumeneku kumachitika panja pazingwe zamagetsi zowonekera, monga nyali zam'misewu.Zida monga magetsi apamsewu ndi masiteshoni akutumiza mafunde.Module yoteteza kuphulika imayang'anizana mwachindunji ndi kusokoneza kwapang'onopang'ono kuchokera ku mzere wamagetsi kumapeto kwa dera.Imatumiza kapena kuyamwa mphamvu yowonjezereka kuti muchepetse chiwopsezo cha ma surges kupita ku mabwalo ena ogwirira ntchito, monga mayunitsi amagetsi a AC/DC pazida zowunikira za LED.
Kwa nyali zapamsewu za LED, mphezi imapangitsa kuti pakhale kukwera kochititsa chidwi pa chingwe chamagetsi.Kuthamanga kwa mphamvu kumeneku kumapangitsa kuti pakhale phokoso lamphamvu pa waya, ndiko kunena kuti, shockwave.Kuphulika kumafalitsidwa ndi induction iyi.Dziko kunja uko likuchuluka.Mafundewa atulutsa nsonga pa sine wave motsatira mzere wotumizira wa 220 v.Pamene nsonga ikulowa mu nyali ya msewu, idzawononga dera la nyali ya msewu wa LED.
Choncho, chitetezo cha mphezi cha nyali za mumsewu wa LED chidzapindulitsa moyo wawo wautumiki, womwe ukufunikira pakali pano.
Kotero izi zimafuna kuti tichite ntchito yabwino yotetezera magetsi a magetsi a LED, apo ayi zidzakhudza kugwiritsidwa ntchito kwake, zomwe zimabweretsa chisokonezo.Ndiye momwe mungatetezere mphezi za magetsi amtundu wa LED?
1.Ikani ndodo yamakono yochepetsera mphezi pa mzati wa nyali yamtundu wa LED
Kulumikizana kodalirika kwamagetsi ndi makina kuyenera kupangidwa pakati pa pamwamba pa chothandizira ndi maziko a ndodo yochepetsera mphezi.Kenaka, chithandizocho chikhoza kukhazikitsidwa kapena kugwirizanitsidwa ndi maukonde apansi a chithandizo chokhachokha ndi chitsulo chathyathyathya.Kukana kwapansi kuyenera kukhala kosakwana 4 ohms.
2. Overvoltage protector imagwiritsidwa ntchito ngati chitetezo chamagetsi kutsogolo kwa nyali yamagalimoto a LED ndikuwongolera mawotchi ndi magwero amagetsi.
Tiyenera kulabadira madzi, chinyezi-umboni, dustproof ndi waya mkuwa wa overvoltage mtetezi chikugwirizana ndi khomo chimango grounding kiyi motero, ndi kukana grounding ndi zosakwana mtengo kukana mwachindunji.
3. Chitetezo cha pansi
Pamsewu wokhazikika, mzati wake ndi kugawa zida zam'tsogolo zimakhala zobalalika, kotero tikufuna kukwaniritsa mfundo imodzi yokhayo idzakhala yovuta.Chifukwa chake, pofuna kuwonetsetsa kuti magetsi amtundu wa LED akugwira ntchito yokhazikika komanso chitetezo chaumwini, mumzati uliwonse womwe umakhala pansi pakugwiritsa ntchito thupi loyimirira lomwe limalumikizidwa ndi netiweki, ndiye kuti, njira zambiri zoyatsira mafunde omwe akubwera pang'onopang'ono amamasulidwa ndi mphezi zina. zofunika chitetezo.
