Chifukwa Chake Kuyesa Kwamatenda Kufunika Kwa Zingwe Za Photovoltaic M'malo Ovuta

Pamene mphamvu ya dzuwa ikupitiriza kulimbikitsa kusintha kwa dziko lonse ku magetsi abwino, kudalirika kwa zigawo za photovoltaic (PV) kwakhala kovuta kwambiri kuposa kale lonse-makamaka m'madera ovuta monga zipululu, denga, zoyandama za dzuwa, ndi nsanja za m'mphepete mwa nyanja. Pakati pa zigawo zonse,PV zingwe ndi njira zopatsirana mphamvu. Kuti muwonetsetse kukhazikika komanso kugwira ntchito kwanthawi yayitali, kuyesa kumodzi kwamakina kumakhala kofunikira:kuyesedwa kwamphamvu.

Nkhaniyi ikuwonetsa zomwe kuyezetsa kwamphamvu kumatanthauza pazingwe za PV, chifukwa chake kuli kofunikira, ndi miyezo iti yomwe imayendetsa, komanso momwe zida ndi kapangidwe ka chingwe zimakhudzira kulimba kwamphamvu.

1. Kodi Kuyesa kwa Tensile mu PV Cables ndi chiyani?

Kuyesa kwamphamvu ndi njira yamakina yomwe imagwiritsidwa ntchito poyesa kuthekera kwa chinthu kapena gawo kukanakukoka mphamvumpaka kulephera. Pankhani ya zingwe za photovoltaic, zimatsimikizira kuchuluka kwa mphamvu zamakina zomwe zigawo za chingwe - monga kusungunula, sheath, ndi conductor - zimatha kupirira zisanathyoke kapena kupotoza.

Pakuyesa kwamphamvu, chitsanzo cha chingwe chimangiriridwa mbali zonse ziwiri ndikukokedwa pogwiritsa ntchito amakina oyesera onsepa liwiro lolamulidwa. Miyezo imatengedwa:

• Kuphwanya mphamvu(kuyezedwa mu Newtons kapena MPa),

• Elongation panthawi yopuma(momwe zimatambasulira zisanachitike), ndi

• Kulimba kwamakokedwe(kupanikizika kwakukulu zomwe zinthu zimatha kupirira).

Mayesero amanjenje amachitidwa pazigawo payekhawa chingwe (kuteteza ndi m'chimake) ndipo nthawi zina msonkhano wathunthu, kutengera zofunika muyezo.

2. N'chifukwa Chiyani Mumayesa Kuyesa Kwambiri Pazingwe za Photovoltaic?

Kuyesa kwamphamvu sikungokhala kwa labotale - kumagwirizana mwachindunji ndi magwiridwe antchito amtundu weniweni.

Zifukwa zazikuluzikulu za ma PV Cables Amafunikira Kuyesedwa kwa Tensile:

• Kupanikizika pakuyika:Pomanga zingwe, kukoka, ndi kupindika, zingwe zimakumana ndi kukangana komwe kungayambitse kuwonongeka kwa mkati ngati mphamvu sizikukwanira.

• Mavuto azachilengedwe:Kuthamanga kwa mphepo, chipale chofewa, kugwedezeka kwa makina (mwachitsanzo, kuchokera ku trackers), kapena kukokoloka kwa mchenga kumatha kukhala ndi mphamvu pakapita nthawi.

• Chitetezo:Zingwe zomwe zimaphwanyidwa zomwe zimang'ambika, kugawanika, kapena kutaya mphamvu zimatha kutaya mphamvu kapena kuwonongeka kwa arc.

• Kutsatira ndi kudalirika:Ma projekiti pamlingo wofunikira, wamalonda, komanso wopitilira muyeso amafuna makina otsimikizika kuti akwaniritse miyezo yapadziko lonse lapansi.

Mwachidule, kuyesa kwamphamvu kumatsimikizira kuti chingwecho chikhoza kupirirakupsinjika kwamakina popanda kulephera, kuchepetsa zoopsa komanso kukonza bata kwa nthawi yayitali.

3. Miyezo ya Makampani Olamulira Kuyesa kwa PV Cable Tensile

Zingwe za Photovoltaic ziyenera kutsata miyezo yolimba yapadziko lonse lapansi yomwe imafotokoza zofunikira zocheperako pamagawo osiyanasiyana a chingwe.

Miyezo Yaikulu Ikuphatikizapo:

• IEC 62930:Imatanthawuza mphamvu zamakokedwe ndi kutalika kwa zotchingira ndi zotchingira zida usanakalamba komanso utatha.

• EN 50618:Muyezo waku Europe wa zingwe za PV, zomwe zimafuna kuyesa kulimba kwamakina kuphatikiza kulimba kwa ma sheath ndi kutchinjiriza.

• TÜV 2PfG 1169/08.2007:Imayang'ana pa zingwe zamakina a PV okhala ndi ma voliyumu mpaka 1.8 kV DC, kuphatikiza zoyeserera zatsatanetsatane komanso zoyeserera zakukweza.

• UL 4703 (ya msika waku US):Zimaphatikizanso zoyeserera zamphamvu pakuwunika zinthu.

Mulingo uliwonse umatanthauzira:

• Mphamvu zocheperako(mwachitsanzo, ≥12.5 MPa ya XLPE kutchinjiriza),

• Elongation panthawi yopuma(mwachitsanzo, ≥125% kapena kupitilira apo kutengera zakuthupi),

• Mikhalidwe yoyezetsa ukalamba(mwachitsanzo, kukalamba kwa uvuni pa 120 ° C kwa maola 240), ndi

• Njira zoyesera(utali wachitsanzo, liwiro, mikhalidwe ya chilengedwe).

Miyezo iyi imawonetsetsa kuti zingwe ndi zolimba mokwanira kuti zikwaniritse zofunikira pakuyika kwa dzuwa padziko lonse lapansi.

4. Momwe Zida Zachingwe ndi Kapangidwe Zimakhudzira Magwiridwe Amphamvu

Sizingwe zonse za PV zomwe zimapangidwa mofanana. Thekapangidwe kazinthundichingwe kupangaamatenga gawo lalikulu pakuzindikira mphamvu zolimba.

Zofunika:

• XLPE (Polyethylene Yophatikizika):Amapereka mphamvu zochulukirapo komanso kukhazikika kwamafuta, omwe amagwiritsidwa ntchito kwambiri mu zingwe za EN 50618.

• PVC:Zotsika mtengo, koma mphamvu zamakina zotsika - zosakonda panja kapena ntchito za PV.

• TPE / LSZH:Zosankha zopanda utsi, zopanda halogen zomwe zimasinthasintha kusinthasintha komanso magwiridwe antchito apakati.

Conductor Impact:

• Mkuwa Wothira:Imawonjezera kukana kwa dzimbiri ndikuwongolera kulumikizana kwamakina ndi insulation.

• Stranded vs. Solid:Makondakitala osokonekera amathandizira kusinthasintha ndikuchepetsa chiopsezo chosweka ndi kukanika kobwerezabwereza.

Kapangidwe Kapangidwe:

• Kulimbikitsa Sheath:Zingwe zina za PV zimaphatikizapo ulusi wa aramid kapena mapangidwe amitundu iwiri kuti awonjezere kukana.

• Multi-core vs. Single-core:Zingwe zamakina ambiri nthawi zambiri zimakhala ndi machitidwe ovuta kumakina koma zimatha kupindula ndi zodzaza zolimbitsa.

Kusankhidwa kwazinthu zapamwamba kwambiri komanso kapangidwe kabwino kamangidwe kabwino kumakulitsa luso la chingwe kuti lithe kuyesa kulimba komanso kuchita bwino m'munda.

Mapeto

Kuyesa kwamphamvu ndi chizindikiro chofunikira chowonetsetsakulimba kwamakinazingwe za photovoltaic. M’malo ovuta—kaya ndi dzuwa lotentha kwambiri, mphepo yamphamvu, kapena kupoperani m’mphepete mwa nyanja—kulephera kwa chingwe sichosankha.

Pomvetsetsa kuyezetsa kovutirapo, kusankha zinthu zovomerezeka, ndikupeza kuchokera kwa opanga ovomerezeka, ma EPC a solar, opanga mapulogalamu, ndi magulu ogula zitha kutsimikizirayotetezeka, yothandiza, komanso yopereka mphamvu kwanthawi yayitali.
