Ma Solar Photovoltaic Cables: Zofunikira Zofunikira Pa Kuyika Kulikonse kwa Dzuwa

-photovoltaic yapamwamba kwambiriPV Cablendi gawo laling'ono la solar system lomwe lakhudza kwambiri ntchito ya moyo wonse, chitetezo ndi ROI. Kusankha PV chingwe choyenera - kondakitala, zokutira, ndi zolumikizira - kumachepetsa kutayika kwa magetsi, kumateteza kulephera komanso kumathandiza kukwaniritsa makhodi (NEC/IEC/UL). Bukhuli likuyankha mafunso asanu ndi atatu omwe ogula, opanga ndi oyika amafunsa, ndipo amapereka mndandanda wazinthu zogulira.

Kodi "zingwe za PV" ndi chiyani ndipo zimasiyana bwanji ndi waya wamba wamagetsi?

Zingwe za PV ndi imodzi-zokonda, kuwala kwa dzuwa-zingwe zosagwira ntchito zopangira ma module a PV ndi mbali ya DC ya makina a PV. Nthawi zambiri amagwiritsa ntchito ma conductor a mkuwa a malata, omangika komanso -zolumikizana ndi polyolefin (XLPO/XPLE) kapena zotchingira zina za UV/heat{4}}zosagwira ntchito. Zingwe za PV zimavoteredwa chifukwa cha kutentha kosalekeza, kuwala kwachindunji{{6}kudzuwa, komanso kukhala kunja kwa nthawi yayitali - zomwe sizikufunika pa mawaya wamba. Miyezo mongaIEC 62930ndiMtengo wa UL4703fotokozerani zomanga ndi kuyesa kwa chingwe cha PV.

Ndi miyezo ndi ziphaso ziti zomwe ndiyenera kuzifuna pogula chingwe cha PV?

Pamafunika zingwe zogwirizana ndi ma PV apano ndi zizindikiro zoyeserera-za gulu lachitatu:

Kodi ndimakula bwanji zingwe za PV (AWG/mm²) - ndi zinthu ziti zofunika?

Kukula kwa chingwe kumayendera zopinga zitatu: ampacity (kuchuluka komwe kuli pano), kutsika kwamagetsi, ndi zovuta zamakina / kukhazikitsa. Gwiritsani ntchitochokulirapokondakitala wofunidwa ndi malamulo a ampacity kapena voltage -kutsika. Zinthu zofunika: kuchuluka kwa zingwe zamakono (kapena inverter inverter current), voteji ya DC, kutentha kwa conductor, kutalika kwa kuthamanga (kumakhudza kutsika kwa magetsi), ndi kutentha kwa malo (kuchepa kwa mphamvu). Lab m'dziko komanso malangizo amakampani amatsindika kuti nthawi zonse muziyang'ana kuchuluka kwa magetsi ndi kutsika kwa magetsi - ndiye gwiritsani ntchito kondakita wamkulu. Kwa PV yokhalamo, oyika nthawi zambiri amakweza AWG imodzi kuti achepetse kutsika kwamagetsi (mwachitsanzo, AWG 10 → AWG 8).Malangizo othandiza:yesetsani kuchepetsa kapena kufananiza ndi 1.5-2% kutsika kwamagetsi pamayendedwe aatali a DC; pamagulu ofunikira atali, recalc pakuyembekezeka kwa kutentha kwakukulu kogwira ntchito.

Kodi ndifunika kutengera kutentha kwanji, magetsi ndi chilengedwe?

Mavoti ochepera ovomerezeka amadalira code ndi malo a polojekiti, koma zofunikira zenizeni:

Kutentha:Adavoteledwa osachepera90 digirimosalekeza (mawaya ambiri a PV adavotera 90-125 digiri). UL 4703 imatchulanso zosankha mpaka madigiri 150 pazomanga zina. UL Standards Store

Voteji:Miyezo wamba ya DC ndi600 V, 1.0 kV ndi 1.5 kV(makina okwera-amagetsi akuchulukirachulukira). Gwiritsani ntchito chingwe chovotera pamwamba pamagetsi a DC. webstore.iec.ch+1

UV & kukana kwanyengo:Kutentha kuyenera kukhala kwadzuwa-kusamva kuwala kwa dzuwa komanso UV-kukhazikika padenga la nyumba, malo otsetsereka komanso malo oyika maliro ngati angafunike. Mayeso (IEC/EN/UL) a UV ndi ukalamba wamafuta

Kodi zolumikizira (MC4 ndi zina) ndizofunikira bwanji, ndipo zimayambitsa mavuto otani?

Zolumikizira ndizofunikira-zofunika kwambiri. Zolumikizira zolakwika kapena zosayikidwa bwino ndizomwe zimayambitsa kulephera kwa kulumikizana kwa PV komanso moto wosowa koma wowopsa. Kuyesa kodziyimira pawokha ndi zoyera zimawonetsa mtundu wa cholumikizira, kapangidwe kake ndi kapangidwe kake zimakhudza kwambiri kudalirika. Gwiritsani ntchito zolumikizira zotsimikiziridwa, zida zoyenera za crimp, ndikuyang'ana torque ndikuyika. Tsatirani mapulani owunikira a O&M kuti muwone kusinthika, kutentha, kapena kulowa kwamadzi.

Ndi zingwe ziti zomwe zili zabwino kwambiri kwa moyo wautali komanso kusakonza pang'ono?
