Kurova kwemheni chinhu chinowanzoitika, kunyanya munguva yekunaya kwemvura. Kukuvadzwa uye kurasikirwa kwavanokonzera kunofungidzirwa kuva mazana emabhiriyoni emadhoraLED streetlight magetsi magetsigore negore pasi rose. Kurova kwemheni kunorongwa sekwakananga uye kusina kunanga. Mheni isina kunanga inonyanya kusanganisira mheni inoitiswa uye inokonzeresa. Nekuti mheni yakananga inopa simba rakawanda kudaro uye simba rekuparadza, magetsi akajairika haagone kumira nazvo. Ichi chinyorwa chichakurukura mheni isina kunanga, iyo inosanganisira zvose zviri zviviri zvakaitwa uye zvakakonzerwa nemheni.
Kuvhiya kunogadzirwa nekurova kwemheni inguva pfupi, kupindira kwenguva pfupi, uye inogona kunge iri surge voltage kana yekuvhiya ikozvino. Inoendeswa kune tambo yemagetsi pamwe netambo dzemagetsi kana dzimwe nzira (inoitisa mheni) kana kuburikidza nemagetsi emagetsi minda (inokonzeresa mheni). Yayo waveform inoratidzirwa nekukurumidza kusimuka kunoteverwa nekudonha zvishoma nezvishoma. Chiitiko ichi chinogona kukanganisa zvinhu zvemagetsi, sezvo kuvhiya kwepakarepo kunodarika kushushikana kwemagetsi ezvakajairwa zvinhu zvemagetsi, zvichivakuvadza zvakananga.
Iko Kudikanwa kweMheni Dziviriro kune LED streetlights
Kune magetsi emumugwagwa e LED, mheni inokonzera kuwedzera mumagetsi emagetsi. Iri simba rekuwedzera rinogadzira masaisai akaerekana pamagetsi emagetsi, anozivikanwa se surge wave. Masurges anofambiswa nenzira iyi inductive. Mhepo yekunze yekuwedzera inogadzira spike mune sine wave ye220V yekufambisa mutsara. Iyi spike inopinda muchiedza chemugwagwa uye inokuvadza LED streetlight circuit.
Kune magetsi emagetsi akangwara, kunyangwe kuvhunduka kwechinguvana kukasakuvadza zvikamu, zvinogona kukanganisa kushanda kwakajairika, zvichikonzera mirairo isiriyo uye kudzivirira magetsi kushanda sezvanga zvichitarisirwa.
Parizvino, nekuti zvigadziriso zvemwenje zve LED zvine zvinodiwa uye zvirambidzo pahukuru hwesimba rekupa simba, kugadzira simba remagetsi rinosangana nekudzivirira mheni zvinodiwa mukati menzvimbo shoma hazvisi nyore. Kazhinji, yazvino GB/T17626.5 chiyero inongokurudzira kuti zvigadzirwa zvisangane nezviyero zve 2kV differential mode uye 4kV common mode. Muchokwadi, aya maratidziro anowira pasi pezvinodikanwa chaizvo, kunyanya zvekushandisa munzvimbo dzakashongedzerwa senge madoko uye materminal, mafekitori ane mahombe emagetsi emagetsi padyo, kana nzvimbo dzinowanzo kurohwa nemheni. Kugadzirisa kunetsana uku, makambani mazhinji emumugwagwa anowanzo wedzera anomira akamira anodzvinyirira. Nekuwedzera yakazvimiririra yekudzivirira mheni mudziyo pakati pekupinza uye yekunze mutyairi we LED, kutyisidzira kwemheni kurova kwekunze kwemutyairi we LED kunoderedzwa, kuve nechokwadi zvakanyanya kuvimbika kwekupa magetsi.
Uye zvakare, pane akati wandei akakosha ekufunga nezve kwakakodzera mutyairi kuisirwa uye kushandiswa. Semuyenzaniso, magetsi anofanirwa kuve akadzikwa zvakavimbika kuti ave nechokwadi chekuti nzira yakagadziriswa yekuti simba rekuvhiya riparare. Matambo emagetsi akatsaurirwa anofanirwa kushandiswa kumutyairi wekunze, kudzivirira mahombe emagetsi emagetsi ari pedyo kudzivirira mavhisi panguva yekutanga. Kuremerwa kwemarambi (kana magetsi emagetsi) pamutsara wega wega webazi kunofanirwa kudzorwa nemazvo kudzivirira mashura anokonzerwa nekuremerwa kwakanyanya panguva yekutanga. Shanduko dzinofanirwa kugadzirwa nenzira kwayo, kuve nechokwadi chekuti switch yega yega inovhurwa kana kuvharwa nhanho-ne-nhanho nzira. Aya matanho anogona kudzivirira zvinobudirira kusevha kwekushanda, kuve nechokwadi chekushanda kwakavimbika kwemutyairi we LED.
TIANXIANG akaona shanduko yeLED streetlightindasitiri uye yakaunganidza ruzivo rwakakura mukugadzirisa zvinodikanwa zvezviitiko zvakasiyana. Chigadzirwa chacho chakavakirwa-mukati mehunyanzvi chekudzivirira mheni zvivakwa uye chapfuura mheni yekudzivirira bvunzo chitupa. Inogona kumira kukanganiswa kwemamiriro ekunze ane mheni yakasimba padunhu, kudzivirira kukuvara kwemidziyo uye kuona kuti chiedza chemumugwagwa chinoshanda zvakasimba kunyange munzvimbo dzinowanzoita mabhanan'ana. Inogona kumira muyedzo wenguva refu yakaoma yekunze nharaunda. Mwero wekuora kwechiedza wakadzikira zvakanyanya kupfuura avhareji yeindasitiri, uye hupenyu hwesevhisi hwakareba.
