Mumakore achangopfuura, teknolojia ye photovoltaic industry yakagadzirwa nekukurumidza uye nekukurumidza, simba rezvikamu rimwechete rave rakakura uye rakakura, ikozvino yetambo yakave yakakura uye yakakura, uye ikozvino yezvikamu zvepamusoro-simba zvasvika kupfuura kupfuura. 17A.
Mukutaura kwegadziriro yehurongwa, kushandiswa kwezvikamu zvepamusoro-simba uye zvinonzwisisika pamusoro-kufananidza zvinogona kuderedza mari yekutanga yekutsvaga mari uye mari pa kilowatt-awa yegadziriro.
Mutengo weAC uye DC tambo muhurongwa unotora chikamu chikuru.Kugadzira uye kusarudzwa kunofanira kuderedzwa sei kuderedza mari?
Kusarudzwa kweDC cables
DC tambo dzinoiswa panze.Inowanzokurudzirwa kusarudza irradiated uye cross-linked photovoltaic special cables.
Mushure mekukwirira-simba erekitironi beam irradiation, chimiro chemorekuru cheiyo insulation layer yetambo inoshanduka kubva pamutsara kuenda kune matatu-dimensional mesh molecular chimiro, uye tembiricha yekudzivirira inokwira kubva kune isiri-yakabatana 70 ℃ kusvika 90 ℃, 105 ℃ , 125 ℃, 135 ℃, uye kunyange 150 ℃, iyo iri 15-50% yakakwirira kudarika ikozvino kutakura kukwanisa kwetambo dzezvakatemerwa zvakafanana.
Inogona kumira zvakanyanya kuchinja kwekushisa uye kukukurwa kwemakemikari uye inogona kushandiswa kunze kweanopfuura makore makumi maviri nemashanu.
Paunenge uchisarudza tambo dzeDC, unofanirwa kusarudza zvigadzirwa zvine zvitupa zvinoenderana kubva kuvagadziri venguva dzose kuti uve nechokwadi chekushandiswa kwekunze kwenguva refu.
Iyo inonyanya kushandiswa photovoltaic DC tambo ndiyo PV1-F 1*4 4 skweya tambo.Nekudaro, nekuwedzera kweiyo photovoltaic module ikozvino uye kuwedzera kweimwe inverter simba, kureba kweDC tambo iri kuwedzera zvakare, uye kushandiswa kwe6 square DC cable kuri kuwedzerawo.
Maererano nemashoko akakodzera, zvinowanzokurudzirwa kuti kurasikirwa kwe photovoltaic DC hakufaniri kudarika 2%.Isu tinoshandisa chiyero ichi kugadzira nzira yekusarudza DC tambo.
Mutsara wekupokana kwePV1-F 1 * 4mm2 DC tambo ndeye 4.6mΩ/mita, uye mutsara wePV 6mm2 DC tambo ndeye 3.1mΩ/mita.Tichifunga kuti simba rekushanda reDC module i600V, kupera kwemagetsi kwe2% ndeye 12V.
Tichifunga kuti iyo module ikozvino 13A, uchishandisa 4mm2 DC cable, kureba kubva kumagumo ekupedzisira kwe module kusvika kune inverter inokurudzirwa kuti isapfuure mamita zana nemakumi maviri (tambo imwe chete, isingabatanidzi matanda akanaka uye asina kunaka).
Kana iri yakakura kudarika chinhambwe ichi, zvinokurudzirwa kusarudza 6mm2 DC tambo, asi zvinokurudzirwa kuti chinhambwe kubva kumagumo ekupedzisira emodule kusvika kune inverter hachipfuuri 170 metres.
Kusarudzwa kwetambo dzeAC
Kuti uderedze mutengo wehurongwa, zvikamu uye inverters yemagetsi emagetsi e photovoltaic haawanzo gadziridzwa muchiyero che1: 1.Pane kudaro, imwe chiyero chepamusoro-kuenzanisa inogadzirwa zvinoenderana nemamiriro ekuvhenekesa, zvinodiwa zveprojekiti, nezvimwe.
Semuenzaniso, kune chikamu che110KW, inverter ye100KW inosarudzwa.Zvinoenderana neiyo 1.1 nguva pamusoro-inofananidza kuverenga paA AC padivi reiyo inverter, iyo yakanyanya kubuda AC inobuda ingangoita 158A.
Kusarudzwa kwetambo dze AC kunogona kutariswa zvichienderana nehupamhi hwekubuda ikozvino kweiyo inverter.Nekuti kunyangwe zvakadii izvo zvikamu zvakapfuura-zvichienderana, iyo yazvino yeiyo inverter AC yekupinda haizombopfuure iyo yakanyanya kuburitsa ikozvino inverter.
Inowanzo shandiswa photovoltaic system AC copper cables dzinosanganisira BVR neYJV nemamwe mamodheru.BVR zvinoreva copper core polyvinyl chloride insulated soft wire, YJV cross-linked polyethylene insulated power cable.
Paunenge uchisarudza, teerera kune voltage level uye tembiricha level yetambo.Sarudza rudzi rwemoto-retardant.Tsanangudzo dzetambo dzinoratidzwa nenhamba yepakati, yezita remuchinjiko-chikamu uye voltage level: single-core bazi tambo tambo yakatarwa kutaura, 1 * zita remuchinjiko-chikamu, senge: 1 * 25mm 0.6 / 1kV, inoratidza 25 square tambo.
Zvinotsanangurwa zveakawanda-musimboti akamonyoroka tambo dzebazi: huwandu hwetambo mune imwechete loop * zita remuchinjiko-chikamu, senge: 3*50+2*25mm 0.6/1KV, inoratidza 3 50 square live waya, 25 square neutral waya uye 25 square ground waya.
Ndeupi musiyano uripo pakati pe-single-core cable uye multi-core cable?
Single-core cable inoreva tambo ine chete conductor mune imwe insulation layer.Multi-core cable inoreva tambo ine inodarika imwe insulated core.Panyaya yekushanda kwekudzivirira, ese ari maviri-musimboti uye akawanda-musimboti tambo dzinofanirwa kusangana nenyika.
Musiyano uripo pakati pe-multi-core cable uye single-core tambo ndeyekuti imwechete-core tambo inodzika yakananga kumagumo ese, uye simbi inodzivirira tambo yetambo inogonawo kugadzira inotenderera ikozvino, zvichikonzera kurasikirwa;
Multi-core tambo inowanzoita matatu-yakakosha tambo, nekuti panguva yekushanda kwetambo, huwandu hwemhepo inoyerera nepakati pematatu cores i zero, uye hapana chakanyanya kukonzeresa voltage kumagumo ese etambo simbi inodzivirira layer.
Kubva pakuona kwesimba redunhu, kune imwechete-musimboti uye akawanda-core tambo, yakayerwa ikozvino kutakura inotakura tambo imwe-yepakati tambo yakakura kupfuura iyo yetatu-yapakati tambo dzechikamu chimwe chete;
Kupisa kwekupisa kwetambo dze-single-core kwakakura kupfuura kwetambo dzema-multi-core.Pasi pemutoro wakafanana kana mamiriro epfupi, kupisa kunogadzirwa ne-single-core cables kuduku kudarika kwe-multi-core cables, iyo yakachengeteka;
Kubva pakuona kwekuiswa kwetambo, tambo dze-multi-core zviri nyore kuisa, uye tambo dzine mukati uye dzakawanda-layer double-layer dziviriro dzakachengeteka;tambo dze-single-core zviri nyore kukotama panguva yekuisa, asi kuomerwa kwekuradzika madaro marefu kwakakura kune imwechete-core tambo pane kune akawanda-core tambo.
Kubva pamaonero ekuisa musoro wetambo, single-core cable misoro iri nyore kuisa uye yakanakira kupatsanurwa kwemutsara.Panyaya yemutengo, mutengo weyuniti ye-multi-core cables wakakwira zvishoma pane we-single-core cables.
Photovoltaic system wiring unyanzvi
Mitsetse ye photovoltaic system yakakamurwa kuita DC uye AC zvikamu.Zvikamu zviviri izvi zvinoda kusungirirwa zvakasiyana.Iyo DC chikamu chakabatana kune zvikamu, uye iyo AC chikamu chakabatana kune magetsi grid.
Kune akawanda tambo dzeDC muzviteshi zvemagetsi zvepakati nepakati.Kuti zvive nyore kugadzirisa mune ramangwana, nhamba dzemutsara wetambo imwe neimwe inofanira kusungirirwa zvakasimba.Mitambo yemagetsi yakasimba uye isina simba inoparadzaniswa.Kana paine mitsara yemasaini, senge 485 kutaurirana, inofanirwa kufambiswa yakaparadzana kudzivirira kukanganiswa.
Paunenge uchifambisa waya, gadzirira makonditi nemabhiriji.Edza kusafumura waya.Ichaita sezviri nani kana waya dzichifambiswa nehorizontally uye vertically.Edza kusave nemajoini etambo mumaconduits uye mabhiriji nekuti anonetsa kuchengetedza.Kana waya dzearuminiyamu dzichitsiva waya dzemhangura, mhangura-aruminiyamu adapters inovimbika inofanira kushandiswa.
Mune iyo yose photovoltaic system, tambo dzinokosha zvikuru chikamu, uye mari yavo yemugove muhurongwa huri kuwedzera.Kana isu tichigadzira chiteshi chemagetsi, isu tinofanirwa kuchengetedza mari yesystem zvakanyanya sezvinobvira tichiona kushanda kwakavimbika kwechiteshi chemagetsi.
Nokudaro, kugadzirwa uye kusarudzwa kweC AC uye DC cables ye photovoltaic systems inonyanya kukosha.
Ndapota inzwa wakasununguka kutibata kuti uwane rumwe ruzivo nezve solar cables.
