Kurova kwemheni chiitiko chinowanzoitika, kunyanya munguva yemvura. Kukuvadzwa nekurasikirwa kwazvinoita zvinofungidzirwa kuva mazana emabhiriyoni emadhora eZvishandiso zvemagetsi zve LED streetlightgore rega rega pasi rose. Kurova kwemheni kunorongwa sekwakananga nekwakasanangurwa. Mheni isina kunanga inonyanya kusanganisira mheni inotungamirwa neinotungamirwa. Nekuti mheni yakananga inopa simba rakakura uye simba rekuparadza, magetsi akajairwa haagone kumira. Chinyorwa chino chichakurukura mheni isina kunanga, inosanganisira mheni inotungamirwa neinotungamirwa.
Kukwira kwesimba kunokonzereswa nekurovera kwemheni iwave inoshanduka, kupindira kwesimba, uye inogona kunge iri voltage inoshanduka kana kuti simba rinoshanduka. Rinopfuudzwa kutambo yemagetsi richitevedza tambo dzemagetsi kana dzimwe nzira (mheni inofambiswa) kana kuburikidza neminda yemagetsi (induced lightning). Mafungu aro anoonekwa nekukwira nekukurumidza kunoteverwa nekudonha zvishoma nezvishoma. Chiitiko ichi chinogona kukanganisa zvakanyanya magetsi, sezvo kukwira kwesimba panguva imwe chete kunopfuura kumanikidzwa kwemagetsi kwezvinhu zvemagetsi, zvichizvikuvadza zvakananga.
Kukosha kwekudzivirira mheni pamwenje ye LED
Kune mwenje yemumugwagwa ye LED, mheni inokonzera kukwira kwemagetsi mumitsetse yemagetsi. Simba iri rinokwira rinoburitsa mafungu akangoerekana aitika pamitsetse yemagetsi, inozivikanwa se surge wave. Kukwira kwemagetsi kunopfuudzwa nenzira iyi ye inductive. External surge wave inogadzira spike mu sine wave ye 220V transmission line. Spike iyi inopinda mu street light uye inokuvadza LED street light circuit.
Kune magetsi akangwara, kunyangwe kuvhunduka kwesimba kwenguva pfupi kusingakuvadze zvikamu, kunogona kukanganisa mashandiro akajairika, zvichikonzera mirairo isiriyo uye kudzivirira simba kuti rishande sezvaitarisirwa.
Parizvino, sezvo magadzirirwo emwenje ye LED ane zvinodiwa uye zvirambidzo pahukuru hwemagetsi ese, kugadzira simba remagetsi rinozadzisa zvinodiwa zvekudzivirira mheni munzvimbo diki hakusi nyore. Kazhinji, standard yeGB/T17626.5 iripo inongokurudzira kuti zvigadzirwa zvisangane nemiyero ye2kV differential mode uye 4kV common mode. Muchokwadi, izvi zvinodikanwa hazvikwani zvakanyanya pane zvinodiwa chaizvo, kunyanya kune mashandisirwo munzvimbo dzakagadzirwa senge maports nematerminals, mafekitori ane michina mikuru yemagetsi iri pedyo, kana nzvimbo dzinowanzoitika mheni. Kugadzirisa kusawirirana uku, makambani mazhinji emwenje yemumugwagwa anowanzo wedzera chinodzvinyirira che surge chakazvimiririra. Nekuwedzera mudziyo wekudzivirira mheni wakazvimirira pakati pechinhu chinopinzwa nedhiraivha ye LED yekunze, njodzi yekurohwa nemheni kune dhiraivha ye LED yekunze inoderedzwa, zvichiita kuti simba rive rakavimbika.
Pamusoro pezvo, pane zvinhu zvakakosha zvekufunga nezvazvo pakuiswa uye kushandiswa kwemutyairi nemazvo. Semuenzaniso, simba rinofanira kunge rakavakirwa zvakanaka kuti pave nenzira yakatarwa yekuti simba rekukwira kwemagetsi riparare. Mitsetse yemagetsi yakatsaurirwa inofanira kushandiswa kumutyairi wekunze, kudzivirira michina mikuru yemagetsi iri pedyo kudzivirira kukwira kwemagetsi panguva yekutanga. Mutoro wese wemarambi (kana magetsi) pamutsetse wega wega webazi unofanirwa kudzorwa nemazvo kudzivirira kukwira kwemagetsi kunokonzerwa nekurema kwakawandisa panguva yekutanga. Maswichi anofanirwa kugadziriswa nemazvo, kuve nechokwadi chekuti swichi yega yega yakavhurwa kana kuvharwa nenzira nhanho nhanho. Matanho aya anogona kudzivirira kukwira kwemagetsi, zvichiita kuti mutyairi we LED ashande nemazvo.
TIANXIANG akaona kushanduka-shanduka kweMwenje wemugwagwa we LEDindasitiri uye yakaunganidza ruzivo rwakakura mukugadzirisa zvinodiwa nemamiriro akasiyana-siyana. Chigadzirwa ichi chine nzvimbo dzekudzivirira mheni dzakavakirwa mukati uye chakapasa chitupa chekudzivirira mheni. Chinogona kutsungirira kukanganiswa nemamiriro ekunze ane mheni akasimba padunhu, kudzivirira kukuvara kwemidziyo uye kuona kuti mwenje wemumugwagwa unoshanda zvakanaka kunyangwe munzvimbo dzinoitika dutu. Chinogona kutsungirira bvunzo dzenzvimbo dzakaoma dzekunze kwenguva refu. Mwero wekuora kwechiedza wakaderera zvikuru pane avhareji yeindasitiri, uye hupenyu hwebasa hwakareba.
