Mumakore achangopfuura, tekinoroji yephotovoltaic industryyakagadzira nekukurumidza uye nekukurumidza.Simba rema single modules rave rakakura uye rakakura, uye ikozvino yetambo yakave yakakura uye yakakura.Ikozvino ye-high-power modules yasvika kupfuura 17A.Mukutaura kwegadziriro yehurongwa, kushandiswa kwezvikamu zvemasimba makuru uye nzvimbo yakachengetedzwa yakachengetwa inogona kuderedza mari yekutanga yekutsvaga mari uye kilowatt-awa mutengo wegadziriro.Mutengo weAC uye DC tambo muhurongwa hauna kuderera.Kugadzira uye kusarudzwa kunofanira kuitwa sei kuderedza mari?
1. Kusarudzwa kwetambo dzeDC
Iyo DC cable inoiswa kunze.Kazhinji inokurudzirwa kusarudza yakakosha photovoltaic tambo dzakave dzakachinjika-yakabatana nemwaranzi.Mushure mekukwirira-simba erekitironi beam irradiation, iyo molecular chimiro chetambo yekudzivirira tambo inoshanduka kubva pamutsara kuenda kune matatu-dimensional network yemamorekuru chimiro, uye tembiricha yekudzivirira inokwira kubva kune isiri-yakabatana 70 ° C kusvika 90 ° C, 105 °. C, 125 ° C, 135 ° C, Kunyange kusvika 150 ° C, ikozvino kutakura simba ndeye 15-50% yakakwirira kudarika iyo yetambo dzezvakatsanangurwa zvakafanana.Inogona kumira zvakanyanya kuchinja kwekushisa uye kukukurwa kwemakemikari uye inogona kushandiswa kunze kweanopfuura makore makumi maviri nemashanu.Paunenge uchisarudza tambo dzeDC, sarudza zvigadzirwa kubva kune vagadziri venguva dzose vane zvitupa zvakakodzera kuti uve nechokwadi chekushandiswa kwekunze kwenguva refu.
Parizvino, inonyanya kushandiswaphotovoltaic DC tambondiyo PV1-F1*4 4 skweya mita tambo.Zvisinei, nekuwedzera kwezvino ye photovoltaic modules uye kuwedzera kwesimba reimwe inverter, kureba kwetambo yeDC kunowedzerawo.6 square metres Kushandiswa kweDC tambo kuri kuwedzera zvakare.
Maererano nemashoko akakodzera, zvinowanzokurudzirwa kuti kurasikirwa kwe photovoltaic DC hakufaniri kudarika 2%.Isu tinoshandisa chiyero ichi kugadzira nzira yekusarudza tambo dzeDC.Mutsetse wekupokana kwePV1-F1 * 4mm² DC tambo ndeye 4.6mΩ/mita, uye mutsara wekupokana kwePV6mm² DC tambo ndeye 3.1 mΩ/mita, tichifungidzira kuti DC module inoshanda voltage i600V, 2% kudonha kwevoltage i12V, tichifungidzira. kuti iyo module yazvino ndeye 13A, uchishandisa 4mm² DC tambo, chinhambwe chiri pakati pekupedzisira kwemodule uye inverter inokurudzirwa kuti isapfuure 120 metres (tambo imwe chete, (kusina matanda akanaka uye asina kunaka), kana chinhambwe chiri chikuru kupfuura ichi. chinhambwe, zvinokurudzirwa kusarudza 6mm² DC tambo, asi zvinokurudzirwa kuti chinhambwe chiri pakati pekupedzisira kwechikamu uye inverter haifanire kudarika 170 metres.
2. Photovoltaic cable kurasikirwa kuverenga
Kuti kuderedza mari yehurongwa, zvikamu uyeinverters ye photovoltaic magetsi zviteshihaawanzo gadziridzwa muchiyero che1: 1.Pane kudaro, mamwe magadzirirwo epamusoro-soro akagadzirwa zvichienderana nemamiriro ekuvhenekesa, zvinodiwa zveprojekiti, nezvimwewo. Semuenzaniso, kune 110KW module uye 100KW inverter, inoverengerwa zvichienderana ne1.1 nguva iyo AC side overmatching ye inverter, iyo yakanyanya AC inobuda ikozvino inenge. 158A.Iyo AC tambo inogona kusarudzwa zvichibva pane yakanyanya kubuda ikozvino yeinverter.Nekuti zvisinei kuti mangani ezvikamu akagadziridzwa, iyo AC yekupinda ikozvino yeiyo inverter haizombopfuure iyo yakanyanya kuburitsa ikozvino inverter.
3. Inverter AC yakabuda parameters
Inowanzo shandiswa AC copper cables for photovoltaic systems dzinosanganisira BVR uye YJV.BVR zvinoreva copper core PVC insulated flexible waya, YJV cross-linked polyethylene insulated power cable.Paunenge uchisarudza, teerera kune voltage level uye tembiricha level yetambo., kusarudza rudzi runodzoreredza moto, iyo tambo yakatarwa inoratidzwa nehuwandu hwemacores, zita remuchinjiko-chikamu uye voltage level: Single-core bazi tambo tambo inomiririra, 1 * zita remuchinjiko-chikamu, senge: 1 * 25mm 0.6 /1kV, zvinoreva 25 square mita yetambo.Multi-core yakamonyoroka tambo yebazi tambo inomiririra, huwandu hwetambo mudunhu rimwe chete * zita remuchinjiko-chikamu, senge: 3*50+2*25mm 0.6/1KV, zvinoreva matatu 50 square live waya, imwe 25 square neutral waya. uye A 25 square ground waya.
