Chifukwa chiyani kuli kofunikira kugwiritsa ntchito zingwe za pv DC pamakina a pv?

Makasitomala ambiri nthawi zambiri amakhala ndi mafunso ngati awa: Chifukwa chiyani pakuyika makina a pv, kulumikizana kofananira kwa ma module a pv kuyenera kugwiritsa ntchito zingwe zodzipatulira za pv DC m'malo mwa zingwe wamba?

Poyankha vutoli, tiyeni tiwone kaye kusiyana pakati pa zingwe za pv DC ndi zingwe wamba:

1. Cable core: Zingwe wamba zimagwiritsa ntchito mawaya amkuwa angwiro, omwe ndi achikasu m'mawonekedwe ndipo amatha kukwaniritsa zofunikira zamagetsi zamagetsi. Chingwe cha pv DC chimagwiritsa ntchito waya wamkuwa wamkuwa, ndipo njirayi ndi yovuta kwambiri kuposa waya wopanda waya. mawonekedwe asiliva.Waya wamkuwa wopangidwa ndi malata ndi wofewa komanso uli ndi mphamvu yabwino yamagetsi.Poyerekeza ndi waya wopanda mkuwa, imatha kuteteza chipolopolo cha mphira kuti zisamamatire, ndipo kukana kwake kwa dzimbiri ndi kukana kwa okosijeni kumakhala kolimba, komwe kumatha kukulitsa moyo wautumiki wa zingwe zofooka zamakono.

2. Insulating shell material: Zingwe wamba nthawi zambiri amagwiritsa ntchito XLPE insulation sheath.PV DC zingwe ndi insulated ndi sheathed ndi irradiated cross-linked polyolefin.The key index "irradiation" nthawi zambiri pambuyo pa kuyatsidwa ndi radiation accelerator, kapangidwe kake ka chingwe. zinthu zidzasinthidwa kuti zigwire ntchito mwamphamvu.Mwachitsanzo:

3. M'malo otentha kwambiri komanso ozizira, kupanikizika ndi kugwada kwa mphamvu kumakhala kolimba, ndipo kumakhala ndi mlingo wina wa kutentha kwa moto, zomwe sizili zophweka kutulutsa malawi otseguka, etc. Komanso, chingwe chapadera cha pv chidzakhala ndi zowonjezera zosanjikiza chitetezo chipolopolo kuposa zingwe wamba.

Mwachidule, chingwe cha pv DC chimakhala ndi moyo wamphamvu komanso kulimba kuposa zingwe wamba, ndipo ndi chingwe cholumikizira choyenera kwambiri pamakina opangira magetsi a pv.Chifukwa chake, poganizira zachitetezo ndi kukhazikika kwa pulogalamu ya pv, muyenera kusankha katswiri.PV DC chingwe.
