Impamvu Ikigereranyo Cyikigereranyo Cyibikoresho bya Photovoltaic Mubidukikije Bibi

Mu gihe ingufu z'izuba zikomeje guha ingufu isi yose yerekeza ku mashanyarazi asukuye, kwizerwa kw'ibikoresho bya sisitemu ya Photovoltaque (PV) byabaye ingorabahizi kuruta mbere hose - cyane cyane ahantu habi nko mu butayu, hejuru y'inzu, imirasire y'izuba ireremba, hamwe na platifomu yo hanze. Mu bice byose,Umugozi wa PV nubuzima bwogukwirakwiza ingufu. Kugirango umenye igihe kirekire kandi ukore neza, ikizamini kimwe cyubukanishi kigaragara mubyingenzi:kwipimisha.

Iyi ngingo irasobanura icyo kwipimisha kwinshi bisobanura insinga za PV, impamvu ari ngombwa, amahame abigenga, nuburyo ibikoresho nuburyo bwa kabili bigira ingaruka kumbaraga zikomeye.

1. Ikizamini cya Tensile ni iki mu nsinga za PV?

Igeragezwa rya Tensile nuburyo bukoreshwa muburyo bwo gupima ibikoresho cyangwa ibikoresho byo kurwanyagukurura imbaragakugeza binaniwe. Kubijyanye ninsinga za Photovoltaque, iragena uburyo ubukanishi bwibikoresho bigize insinga - nka insulation, sheath, hamwe nuyobora - bishobora kwihanganira mbere yo kumena cyangwa guhindura.

Mu kizamini gikomeye, umugozi wicyitegererezo ufatirwa kumpande zombi ugakururwa ukoresheje aimashini igerageza kwisi yoseku muvuduko ugenzurwa. Ibipimo bifatwa kuri:

• Imbaraga(bipimirwa muri Newtons cyangwa MPa),

• Kuramba mu kiruhuko(uko irambuye mbere yo gutsindwa), na

• Imbaraga(guhangayikishwa cyane ibikoresho birashobora kwihanganira).

Ibizamini bya Tensile bikorerwa kuriburi cyiciroya kabili (insulation na sheath) kandi rimwe na rimwe inteko yuzuye, bitewe nibisabwa bisanzwe.

2. Kuki Gukora Ikizamini cya Tensile ku nsinga za Photovoltaque?

Kwipimisha cyane ntabwo ari laboratoire gusa - bifitanye isano itaziguye n'imikorere ya kabili.

Impamvu z'ingenzi insinga za PV zisaba kwipimisha:

• Guhangayikishwa no kwishyiriraho:Mugihe cyo guhambira, gukurura, no kunama, insinga zihura nimpagarara zishobora guteza ibyangiritse imbere niba imbaraga zidahagije.

• Ibibazo by’ibidukikije:Umuvuduko wumuyaga, imitwaro yurubura, kunyeganyega (urugero, uhereye kubakurikirana), cyangwa isuri yumusenyi irashobora gukoresha imbaraga mugihe.

• Ubwishingizi bw'umutekano:Intsinga ziri mubibazo bivunika, bigabanije, cyangwa gutakaza ubushobozi birashobora gutera imbaraga gutakaza ingufu cyangwa amakosa ya arc.

• Kubahiriza no kwizerwa:Imishinga mubikorwa byingirakamaro, ubucuruzi, nibidukikije bikenera ibintu byemewe byemewe kugirango byuzuze ibipimo byisi.

Muri make, ibizamini bya tensile byemeza ko umugozi ushobora kwihanganiraguhangayikishwa nubukanishi nta gutsindwa, kugabanya ingaruka no kuzamura umutekano muremure.

3. Ibipimo byinganda bigenga PV Cable Tensile Ikizamini

Intsinga ya Photovoltaque igomba kubahiriza amahame akomeye mpuzamahanga agaragaza byibuze ibisabwa byibuze kubice bitandukanye byumugozi.

Ibipimo by'ingenzi birimo:

• IEC 62930:Kugaragaza imbaraga zingana no kurambura kubwo kubika no gukata ibikoresho mbere na nyuma yo gusaza.

• EN 50618:Igipimo cy’iburayi ku nsinga za PV, gisaba ibizamini byo gukomera gukomeye harimo imbaraga zingana zibyatsi no kubika.

• TÜV 2PfG 1169 / 08.2007:Yibanze ku nsinga za sisitemu ya PV ifite amanota agera kuri 1.8 kV DC, harimo ibisobanuro birambuye byateganijwe kandi birebire.

• UL 4703 (ku isoko ryo muri Amerika):Harimo kandi ibizamini byimbaraga mugihe cyo gusuzuma ibintu.

Buri cyiciro gisobanura:

• Imbaraga ntarengwa(urugero, ≥12.5 MPa yo kubika XLPE),

• Kuramba mu kiruhuko(urugero, ≥125% cyangwa irenga bitewe nibikoresho),

• Ibizamini byo gusaza(urugero, gusaza kw'itanura kuri 120 ° C mu masaha 240), na

• Uburyo bwo gukora ibizamini(uburebure bw'icyitegererezo, umuvuduko, ibidukikije).

Ibipimo ngenderwaho byemeza ko insinga ziramba bihagije kugirango zuzuze ibisabwa n’izuba ku isi.

4. Uburyo Cable Ibikoresho nuburyo bigira ingaruka kumikorere ya Tensile

Ntabwo insinga zose za PV zakozwe zingana. UwitekaIbikoreshonaigishushanyo mboneraGira uruhare runini mu kumenya imbaraga zingana.

Ingaruka z'ibikoresho:

• XLPE (Polyethylene ihuza):Tanga imbaraga zisumba izindi hamwe nubushyuhe bwumuriro, bikunze gukoreshwa muri insinga za EN 50618.

• PVC:Byinshi bihendutse, ariko imbaraga zubukanishi-ntibikunzwe cyane hanze cyangwa ibikorwa-bifashisha PV.

• TPE / LSZH:Umwotsi muke, halogen idafite amahitamo aringaniza imikorere kandi igereranije imikorere.

Ingaruka z'abayobora:

• Umuringa wacuzwe:Ongeraho kurwanya ruswa kandi utezimbere guhuza imashini hamwe no kubika.

• Guhagarara hamwe na Solid:Abayobora bahagaze batezimbere kandi bagabanya ibyago byo kumeneka mugihe cyinshi.

Igishushanyo mbonera:

• Gushimangira ibyatsi:Intsinga zimwe za PV zirimo fibre ya aramid cyangwa ibishushanyo mbonera byongeweho birwanya ubukana.

• Ibice byinshi-vuga-Intangiriro-imwe:Intsinga nyinshi-isanzwe ifite imyitwarire igoye cyane ariko irashobora kungukirwa no kuzuza imbaraga.

Guhitamo ibikoresho byujuje ubuziranenge hamwe nuburyo bunoze bwo gushushanya byongera cyane umugozi ubushobozi bwo gutsinda ibizamini kandi bigakorwa mubihe byumurima.

Umwanzuro

Ikizamini cya Tensile ni igipimo cyibanze cyo kwemeza koubukanishiy'insinga z'amashanyarazi. Mu bihe bigoye - haba munsi yizuba ryinshi, umuyaga mwinshi, cyangwa spray yo hanze -kunanirwa kwa kabili ntabwo ari amahitamo.

Mugusobanukirwa ibizamini bikaze, guhitamo ibicuruzwa byujuje ubuziranenge, hamwe nisoko ryabashinzwe gukora ibyemezo, izuba rya EPC, abashinzwe iterambere, hamwe nitsinda ryamasoko birashobora kwemezaumutekano, gukora neza, no gutanga amashanyarazi maremare.

Urashaka insinga za PV zujuje ubuziranenge bwa IEC, EN, cyangwa TÜV?
Umufatanyabikorwa hamweDanyang Winpower Wire na Cable Mfg Co, Ltd.ninde utanga raporo yubushakashatsi bwuzuye hamwe nibikoresho bikurikirana kugirango umushinga wawe wizuba uhagarare mugihe.
