Chinoongorora chiedza chezuva (photovoltaic panel EL detector) imhando yemudziyo unoshandiswa kuona chiedza chezuva (photovoltaic panel). Chakavakirwa papfungwa ye electroluminescence ye crystalline silicon. Electroluminescence (el) chiitiko umo voltage inoshandiswa inokurumidzisa kufamba kwevatakuri muRondedzero yezvinhu zve semiconductor pasi pesimba remagetsi, zvichishandura chikamu chesimba re kinetic kuita simba rinopenya. Chinoongorora chiedza chezuva (photovoltaic panel EL detector) chinoshandisa iyi pfungwa kutora mufananidzo we crystalline silicon uri pedyo ne infrared nekamera ye infrared ine resolution yepamusoro uye kuwana mufananidzo wesero.
Basa guru re photovoltaic panel EL detector nderekuona nemazvo zvikanganiso zvakasiyana-siyana zve photovoltaic panel, ma parameter anosanganisira gate breaking, crack, fragment, fragment, braze welding, sintered mesh, black core, Letter boxing, blending, low efficiency chip, Edge etching, PID, attenuation, hot spot attenuation, nezvimwewo. Zvikanganiso izvi zvinogona kukanganisa mashandiro uye mhando yema photovoltaic panels uye, kana zvikasaonekwa uye kugadziriswa nenguva, zvinogona kukanganisa kushanda zvakanaka uye kugadzikana kwe solar power system yese.
Pamusoro pekukwanisa kuona nemazvo zvikanganiso zvePV panels, PV panel EL detector ine zvimwe zvakanakira. Semuenzaniso, ine kunyatsojeka uye kushanda zvakanaka, inogona kuona nekukurumidza uye nemazvo nzvimbo uye rudzi rwezvikanganiso. Pamusoro pezvo, EL detector ine mukana wekuyedza Destructive wekuti haizokonzere kukuvara kwemuviri kune photovoltaic panel iri kuyedzwa kana kukanganisa mashandiro ayo.
Mifananidzo yebvunzo dzeEL dzakakodzerwa ndeiyi inotevera:
Heano mamwe ematambudziko akajairika mumapaneru e photovoltaic:
Bhatiri rakatsemuka
(1). Zvinokonzera: panel yebhatiri yakatsemuka nekuda kwesimba rekunze panguva yekuwelda kana kurapwa; patembiricha yakaderera, panel yebhatiri haina kugadziriswa preheat, uye mushure menguva pfupi yekupisa kwakanyanya, yakangoerekana yaonekwa ichikura, zvichikonzera kutsemuka; Tembiricha yebhatiri yakanyanya kukwira panguva yekuwelda kamwe chete kana serial welding.
(2). Mhedzisiro yemodule: inokonzera kudzikira kwesimba remodule, uye mhedzisiro yenzvimbo inopisa ichakonzerwa kana module ikashanda kwenguva yakareba, izvo zvinozokanganisa zvakananga mashandiro ebhatiri kusvika module yapiswa uye yabviswa.
(3). Matanho ekudzivirira: panguva yekusanganisa kana kugadzirisa kudzivirira kukanganiswa kwesimba rekunze pabhatiri, panguva yekusanganisa bhatiri nebhatiri rimwe chete kana kuti tandem kuti rigadziriswe, tembiricha yekushanda kwesimbi yemagetsi inofanira kusangana nezvinodiwa zvehunyanzvi zvekugadzirwa kwayo.
Gedhi Rakatyoka
(1). EL imaging features: kubva pamufananidzo weEl, pane mitsetse yakatwasuka pakati pemitsetse miviri yegrid, uye kune mitsetse yakasviba iri pamutsetse mukuru wegrid wesero. Panguva imwe chete, kusimba kwechiedza chisina kusimba kana kusapenya pagrid thin kunonyanya kukonzerwa nemasero asina kubatana.
(2). Zvikonzero: Chikonzero chikuru chekukuvadzwa kwegedhi ndiko kutyoka kwegedhi rakanaka uye kurasikirwa kwegedhi rakanaka, izvo zvinotungamira kumutsara wegedhi guru uye mutsara wegedhi rakanaka haugone kuumba denderedzwa. Panguva imwe chete, grid haina welding yakajairika kana kudhinda bhodhi rebhatiri, mhando yekudhinda skrini haina kunaka kana ma parameter ekudhinda skrini haana kuiswa zvakanaka, kucheka silicon isina kufanana, kukanganisa.
(3). Mhedzisiro yemodule: nepo ichideredza kushanda kwe photovoltaic module, haina kunaka pakuunganidza magetsi.
(4). Matanho ekudzivirira: kugadzirisa zvine musoro maparamita ekudhinda skrini, kuunganidzwa kwezvinhu zvechidzitiro, kugadzira maitiro ekushanda akajairwa echidzitiro, kutarisa panguva chaiyo. RS inogona kuderedza zvakanyanya kuputsika kwegedhi rekudhinda skrini, panguva imwe chete inogona kuve nemuchina wekurongedza otomatiki wekutarisa online.
Chipu nhema
(1). EL imaging features: mumufananidzo weEL, unogona kuona madenderedzwa akadzika anopenya zvishoma nezvishoma kubva pakati kusvika kumucheto wesero. Chikamu chebhatiri chitema uye mufananidzo unoita seusina kusimba kana kuti usingavhenekeri. Izvi zvinoumba nzvimbo yakamanikana, kana paine simba, pakati pebhatiri unoita senzvimbo nhema.
(2). Mukuita kwe silicon rod crystallization, high segration coefficient ye silicon rod ine chekuita zvakananga nekunyunguduka kwe oxygen, uye silicon material inosvibiswa kusvika padanho rakasiyana, zvichiita kuti chikamu chebhatiri chiite dema. Panguva imwe chete, nekuda kwekupfupisa nguva yekusimba kwedivi, kuburitswa kwekupisa kwakavanzika uye kuenderana kwetembiricha yekunyunguduka kwemvura hazvisi zvakanyanya, kukurumidza kwekukura kwe crystal kunowedzera, uye chikonzero chikuru chekusagadzikana kwemukati ndiko kushushikana kwakanyanya kwekupisa.
(3). Kukanganiswa kwechikamu: mushure mekunge chip nhema chaonekwa muchikamu, kumhanya kwenguva refu kunokonzera kuputsika kwekupisa, kana curve yechikamu chekuyedza IV, curve ikaonekwa sechimiro chemanera, kumhanya kwenguva refu kuchaita kuti simba rekubuda kwechikamu ridzike.
(4). Matanho ekudzivirira: gadzirisa zvine musoro chiyero chekuomesesa kwesimbi uye kunyungudika kweokisijeni musimbi yesilicon kuti usasvibiswe nezvinhu zvesilicon.
Chip nhema yeShort Circuit (chip nhema isiri yeshort circuit)
(1). Hunhu hwemifananidzo yeEL: mamodule e photovoltaic munzvimbo yakati achaonekwa chidimbu chimwe kana kupfuura cheBattery nhema chose.
(2). Zvinokonzera: kupfupika kwema electrode pakati pe positive ne negative, kuchinjika kwe reverse pakati pe positive ne negative electrodes e junction box diode, connection isina kunaka uye kuchinjika kwe virtual pakati pe electrodes positive ne negative, nezvimwewo, mixed low-efficiency cell units, uye silicon wafers dzisina kunaka kana ma N-type wafers anoshandiswa zvisizvo. Kusavapo kwePN junctions ndeimwe yezvikonzero nei EL imaging iri nhema zvachose.
(3). Mhedzisiro yechikamu: chiyero chekuzadza uye simba rekubuda kwechikamu zvichakanganiswa zvakanyanya. Simba rekubuda kwePV module yese raderedzwa, uye simba guru reIV characteristic curve raderedzwa.
(4). Kungwarira: kana bhatiri rakasungirirwa, solder inosiyiwa pamucheto kudzivirira majoini esolder patembiricha yakaderera. Mushure mekunge assembly yaiswa laminated, tarisa kana junction box diode yakasungirirwa uye kana lead wire yakasungirirwa zvisina kujairika.
Muchidimbu, photovoltaic panel EL detector chishandiso chakakosha chekuona, mu solar power system ine basa rakawanda. Haingogone chete kuvandudza mashandiro ekuchinja kwe photoelectric, kuderedza mari, kukurudzira kukura kwesimba rinogona kuvandudzwa, asiwo kuve nechokwadi chekugadzikana uye kushanda zvakanaka kwe solar power system.
