Eminyakeni yakamuva,izimpawu zethrafikhi zelangasezithandwa kakhulu njengesixazululo sokuphathwa kwethrafikhi esiqhubekayo nesisebenzayo. Izimpawu zihlonyiswe ngamaphaneli elanga asebenzisa amandla elanga ukusebenza, okwenza kube yindlela engcono kakhulu kunezimpawu zendabuko ezisebenzisa igridi. Kulesi sihloko, sizohlola ukuthi izimpawu zethrafikhi zelanga zisebenza kanjani nokuthi zinganikela kanjani ohlelweni lokuphathwa kwethrafikhi oluzinzile.
Isimiso sokusebenza sezimpawu zethrafikhi zelanga silula kodwa sihlakaniphile. Lezi zimpawu zifakwe amaseli e-photovoltaic (PV), avame ukubizwa ngokuthi amaphaneli elanga, aguqula ukukhanya kwelanga kube ugesi. Lo gesi ube usugcinwa kumabhethri aphinde ashajwe kabusha ukuze kunikwe amandla izibani ze-LED zesibonakaliso kanye nanoma yiziphi ezinye izingxenye ze-elekthronikhi.
Amaseli e-photovoltaic akhiqiza ugesi oqondile lapho ukukhanya kwelanga kushaya iphaneli yelanga. I-inverter ibe isiguqula amandla kagesi abe ugesi oshintshanayo (i-AC) ukuze kunikwe amandla izibani ze-LED ezimpawini zomgwaqo. Ngesikhathi esifanayo, ugesi oweqile okhiqizwa amaphaneli elanga ugcinwa ebhethri, okunikeza amandla okusekela lapho ukukhanya kwelanga kunganele.
Kunezinzuzo eziningana zokusebenzisa amandla elanga ezimpawini zomgwaqo. Okokuqala, kunciphisa ukuthembela kugridi, okwenza izimpawu zethrafikhi yelanga zibe yisisombululo esizinzile nesingabizi kakhulu. Njengoba kugcizelelwa kakhulu amandla avuselelekayo, izimpawu zethrafikhi yelanga zihambisana nokucindezela komhlaba wonke kwekusasa eliluhlaza nelizinzile.
Ngaphezu kwalokho, izimpawu zethrafikhi zelanga zinikeza ukuguquguquka okukhulu ekubekweni kwazo njengoba kungadingeki zixhunywe kugridi. Lokhu kusho ukuthi zingafakwa ezindaweni ezikude, ezindaweni zokwakha, noma ezindaweni zasemakhaya lapho ukufinyelela kugridi kungase kube kuncane noma kungabikho khona. Lokhu kuzenza zibe yisisombululo esifanele sezidingo zesikhashana zokuphathwa kwethrafikhi njengokusebenza komgwaqo noma izimpawu ezisebenzayo.
Ngaphezu kwalokho, izimpawu zomgwaqo zelanga zinegalelo ekuphepheni nasekubonakaleni okuphelele kwabasebenzisi bomgwaqo. Izibani ze-LED ezisetshenziswa ezimpawini zelanga zibonakala kakhulu ngisho nasezimweni zokukhanya okuphansi, okuqinisekisa ukuthi abashayeli nabahamba ngezinyawo bangabona kalula futhi bachaze ulwazi oluboniswe esiphambanweni. Lokhu kubaluleke kakhulu ekuphathweni nasekuphepheni kwezimoto, njengoba izimpawu ezibonakalayo zibalulekile ekuvimbeleni izingozi nasekugcineni ithrafikhi ihamba.
Ngaphezu kwezinzuzo ezingokoqobo, izimpawu zomgwaqo zelanga nazo zinezinzuzo ezibalulekile zemvelo. Ngokusebenzisa amandla elanga, lezi zimpawu zinciphisa ukusetshenziswa kukaphethiloli wezinto ezilahliwe futhi zinciphise umthelela wekhabhoni ohlotshaniswa nezimpawu zendabuko ezisebenzisa igridi. Lokhu kusiza ekudaleni indawo ehlanzekile nezinzile, ngokuhambisana nemizamo yomhlaba wonke yokulwa nokushintsha kwesimo sezulu nokunciphisa ukukhishwa kwamagesi abangela ukushisa.
Nakuba isimiso sokusebenza sezimpawu zethrafikhi zelanga silula, ubuchwepheshe obusemuva kwazo buyashintsha. Intuthuko ekusebenzeni kahle kwamaphaneli elanga, umthamo wokugcina ibhethri, kanye nobuchwepheshe bokukhanyisa i-LED kuyaqhubeka nokuthuthukisa ukusebenza nokuthembeka kwezimpawu zethrafikhi zelanga. Lokhu kusho ukuthi lezi zimpawu azigcini nje ngokuba yisisombululo esiqhubekayo kodwa futhi ziyisisombululo esisebenzayo nesisebenzayo sezidingo zokuphathwa kwethrafikhi.
Ngamafuphi, isimiso esisebenzayo sezimpawu zethrafikhi zelanga ukusebenzisa amandla elanga ukukhiqiza ugesi ngamaseli e-photovoltaic. Lesi sixazululo esiqhubekayo nesisebenzayo sinikeza izinzuzo eziningi, okuhlanganisa ukusebenza kahle kwezindleko, ukuguquguquka kwesakhiwo, ukuphepha okuthuthukisiwe nokubonakala, kanye nokusimama kwemvelo. Njengoba isidingo sezixazululo zokuphathwa kwethrafikhi esiqhubekayo nesisebenzayo siqhubeka nokukhula, izimpawu zethrafikhi zelanga zizodlala indima ebaluleke kakhulu ekwakheni ikusasa lethrafikhi kanye nokuphepha komgwaqo.
Uma unesifiso sezimpawu zethrafikhi zelanga, wamukelekile ukuxhumana nomkhiqizi uQixiang kuthola ikhotheshini.
