Nei Tensile Yekuyedza Iine Nyaya YePhotovoltaic Cables muHash Environments

Sezvo simba rezuva richiramba richipa simba kushanduka kwepasi rose kumagetsi akachena, kuvimbika kwe photovoltaic (PV) system components kwave kwakaoma kudarika kare-kunyanya munzvimbo dzakaoma serenje, matenga edzimba, mhepo yezuva inoyangarara, uye mapuratifomu ekumahombekombe. Pakati pezvikamu zvese,PV tambo ndiwo mararamiro ekufambisa simba. Kuti ive nechokwadi chekugara kwenguva refu uye kuita, imwe yemishini bvunzo inomira pachena mukukosha:tensile test.

Ichi chinyorwa chinoongorora zvinorehwa nekuyedza tambo dzePV tambo, nei zvichikosha, ndezvipi zviyero zvinoitonga, uye kuti zvinhu uye chimiro chetambo zvinokanganisa sei simba rekusimba.

1. Chii chinonzi Tensile Testing muPV Cables?

Tensile test inzira yemuchina inoshandiswa kuyera kugona kwechinhu kana chikamu chekurambakudhonza masimbakusvika pakukundikana. Panyaya ye photovoltaic cables, inotarisa kuti yakawanda sei mechanical stress iyo cable components-senge insulation, sheath, uye conductor-inogona kumira isati yapwanyika kana kukanganisa.

Muyedzo yekumanikidza, sampu yetambo inosungirirwa kumigumo yese uye kudhonzwa nepakati uchishandisa auniversal test machinenekumhanya kunodzorwa. Zviyero zvinotorwa kune:

• Kuputsa simba(yakayerwa muNewtons kana MPa),

• Elongation panguva yekuzorora(yakawanda sei inotambanudza isati yakundikana), uye

• Kusimba simba(kunyanya kushushikana izvo zvinhu zvinogona kutsungirira).

Tensile bvunzo dzinoitwa pazvidimbu zvegayetambo (insulation uye sheath) uye dzimwe nguva gungano rakazara, zvichienderana nezvinodiwa zvakajairwa.

2. Sei Kuita Tensile Testing pa Photovoltaic Cables?

Tensile kuyedzwa haingori murabhoritari chimiro - inopindirana zvakananga nechaiyo-yenyika tambo kuita.

Zvikonzero Zvikuru PV Cables Inoda Tensile Kuedzwa:

• Installation stress:Panguva yekubatanidza tambo, kudhonza, uye kupeta, tambo dzinoratidzwa kune tension iyo inogona kukonzera kukanganisa mukati kana simba risina kukwana.

• Zvinetso zvezvakatipoteredza:Kudzvinyirirwa nemhepo, kuremerwa nechando, kuzunguzika kwemuchina (semuenzaniso, kubva kumatracker), kana kukukurwa kwejecha kunogona kushandisa simba nekufamba kwenguva.

• Simbiso yekuchengeteka:Matambo ari pasi pekunetsana anotsemuka, kupatsanurwa, kana kurasikirwa neconductivity anogona kukonzera kurasikirwa kwesimba kana kukanganisa arc.

• Kutevedzera uye kuvimbika:Mapurojekiti ari muutility-scale, kutengeserana, uye yakanyanyisa nharaunda inoda certified mechanic properties kuti isangane nezviyero zvepasi rose.

Muchidimbu, tensile yekuyedza inovimbisa kuti tambo inogona kumiramechanical stress pasina kukundikana, kuderedza njodzi nekuvandudza kugadzikana kwenguva refu.

3. Indasitiri Mitemo Inotonga PV Cable Tensile Testing

Photovoltaic tambo dzinofanirwa kuenderana neyakaomesesa miyero yepasirese iyo inodonongodza zvidiki zvinodikanwa zvezvikamu zvakasiyana zvetambo.

Mitemo Yakakosha Inosanganisira:

• IEC 62930:Inotsanangura kusimba kwesimba uye kurebesa kwekudzivirira uye sheathing zvinhu pamberi uye mushure mekukwegura.

• EN 50618:Iyo yeEuropean chiyero chePV tambo, inoda bvunzo dzekusimba kwemechini kunosanganisira kusimba kwesimba remasheti uye insulation.

• TÜV 2PfG 1169/08.2007:Inotarisa pamatambo ePV masisitimu ane voltage ratings anosvika 1.8 kV DC, kusanganisira yakadzama tensile uye elongation bvunzo zvinodiwa.

• UL 4703 (yemusika weUS):Inosanganisirawo tensile simba bvunzo panguva yekuongorora zvinhu.

Chimwe nechimwe chiyero chinotsanangura:

• Minimum tensile simba(semuenzaniso, ≥12.5 MPa yeXLPE insulation),

• Elongation panguva yekuzorora(semuenzaniso, ≥125% kana kupfuura zvichienderana nezvinhu),

• Kuchembera bvunzo mamiriro(semuenzaniso, kuchembera kwevheni pa120 ° C kwemaawa 240), uye

• Maitiro ekuedza(kureba kwemuenzaniso, kumhanya, mamiriro ezvakatipoteredza).

Aya mazinga anovimbisa kuti tambo dzakasimba zvakaringana kuzadzisa zvinodiwa zvekuiswa kwesolar kutenderera pasirese.

4. Mashandisiro eCable Materials uye Structure Influence Tensile Performance

Haasi ese maPV tambo anogadzirwa akaenzana. Thekuumbwa kwezvinhuuyecable designkuita basa guru pakusarudza simba rekusimba.

Material Impact:

• XLPE (Muchinjikwa-Yakabatanidzwa Polyethylene):Inopa simba repamusoro rekusimba uye kugadzikana kwekupisa, kunowanzoshandiswa muEN 50618-yakatemerwa tambo.

• PVC:Inodhura zvakanyanya, asi yakaderera simba remuchina-inosarudzika kunze kana utility-chiyero chePV application.

• TPE / LSZH:Yakaderera-utsi, halogen-yemahara sarudzo dzinoenzanisa kuchinjika uye zvine mwero tensile kuita.

Conductor Impact:

• Tinned Copper:Inowedzera corrosion resistance uye inonatsiridza kusungirirwa kwemakanika nekuisa insulation.

• Stranded vs. Solid:Stranded conductors inovandudza kuchinjika uye kuderedza njodzi yekutyoka pasi pekunetsekana kwakadzokororwa.

Structural Design:

• Sheath Reinforcement:Mamwe tambo dzePV dzinosanganisira aramid faibha kana maviri-sheath madhizaini ekuwedzera tensile kuramba.

• Multi-core vs. Single-core:Multi-core tambo dzinowanzo kuve neakaomesesa mechanicha maitiro asi anogona kubatsirwa kubva kune akasimbiswa mafirita.

Kusarudzwa kwezvinhu zvemhando yepamusoro uye dhizaini yakagadziridzwa dhizaini inosimudzira zvakanyanya kugona kwetambo kupasa bvunzo uye kuita pasi pemamiriro emunda.

Mhedziso

Tensile bvunzo ndiyo yakakosha bhenji yekuona iyokusimba kwemichinaye photovoltaic cables. Munzvimbo dzakaoma—kungava pasi pezuva rinopisa, mhepo ine simba, kana pfapfaidzo yepamhenderekedzo yegungwa—kukundikana kwetambo haisi sarudzo.

Nekunzwisisa kuyedza kusimba, kusarudza zvigadzirwa zvinoenderana, uye kutsvaga kubva kune vanogadzira vanogadzira, solar EPCs, vanogadzira, uye zvikwata zvekutenga zvinogona kuve nechokwadi.yakachengeteka, inobudirira, uye inogara kwenguva refu kuendesa magetsi.

Kutsvaga PV tambo dzinosangana neIEC, EN, kana TÜV tensile zviyero?
