Nzira yekusarudza Photovoltaic Cables ye Photovoltaic Systems?

Mutengo wemhangura wakakwira munguva pfupi yapfuura, uye mutengo wetambo wakakwirawo.Mumutengo wakakwana we photovoltaic systems, mutengo wezvinhu zvakadai sephotovoltaic cablesuye maswichi akadarika ayo e inverters, uye akaderera chete pane zvikamu uye zvinotsigira.Kana isu tawana kudhirowa kwekambani yekugadzira uye kuziva ma parameter emhando yewaya, ukobvu, ruvara, nezvimwe, tinogona kutanga kutenga nerunyorwa.Nekudaro, kune mhando dzakawanda dzewaya, uye vashandisi vazhinji vanoshamiswa nemhando dzakawanda dzewaya.Ndeipi iri nani?

Pakusarudza tambo ye photovoltaic, tinofanira kutanga tatarisa zvinhu zviviri: conductor uye insulating layer.Chero bedzi zvikamu zviviri izvi zvakanaka, kunaka kwewaya kunoratidzwa kuve kwakavimbika.

1. Muitisi

Bvisa kusungirira kwetambo kuratidza waya yemhangura mukati, uyu ndiye conductor.Tinogona kutonga mhando yemakondakita kubva pamaonero maviri:

01. ruvara

Kunyange zvazvo vatungamiri vose vanonzi "mhangura", havasi 100% mhangura yakachena, uye pachava nekusachena mukati mavo.Izvo zvakanyanya kusvibiswa zvirimo, zvakanyanya kuipa conductivity ye conductor.Huwandu hwetsvina huri mukondakita huchawanzo ratidzwa muruvara.

Mhangura yemhando yakanakisa inonzi "mhangura tsvuku" kana "tsvuku tsvuku" -sezvo zita rinoratidza, ruvara rwemhando iyi yemhangura yakatsvuka, purplish, purplish-tsvuku, rima tsvuku.

Iyo yakaipisisa mhangura, iyo inoreruka ruvara uye yakawanda yero, iyo inonzi "ndarira."Imwe mhangura ndeyeyero yakareruka-kusachena kwemhangura iyi kwatokwira zvakanyanya.

Mamwe acho machena, iwaya dzinenge dziri mberi.Waya dzemhangura dzakaputirwa neturu yetini, chikonzero chikuru ndechekudzivirira mhangura kubva kune oxidizing kuita patina.Iko conductivity yepatina yakashata zvikuru, iyo inowedzera kupikisa uye kupisa kupisa.Pamusoro pezvo, kupenya waya dzemhangura kunogona zvakare kudzivirira iyo insulation rabha kubva kunamira, kusviba uye brittleness yepakati, uye kuvandudza kwayo solderability.Photovoltaic DC tambo dzinenge dzakaiswa waya dzemhangura.

02. ukobvu

Kana iyo dhayamita yewaya yakafanana, iyo yakawedzera kondakita, iyo yakasimba conductivity-kana ichienzanisa ukobvu, chete conductor inofanira kuenzaniswa, uye ukobvu hweiyo insulating layer haifaniri kuwedzerwa.

Edza kushandisa tambo dzakawanda dzewaya inochinjika.Pane imwe chete core waya mutambo, inonzi single core wire, yakadai seBVR-1*6;kune akawanda core waya mutambo, seYJV-3 * 25 + 1 * 16, Inonzi multi-core wire;imwe neimwe yepakati waya inoumbwa netambo dzakawanda dzemhangura uye inonzi waya yakawanda-strand, iyo inenge yakapfava uye yakakodzera kune photovoltaic systems.Waya ine tambo imwe chete inogona kuroverwa zvakananga pane iyo terminal, asi iyo imwe-yakasungwa waya yakaoma uye haina kukodzera kuiswa munzvimbo dzine diki inotenderera radius.Kune akawanda-strand waya idiki pane gumi nematanhatu square metres, zvinokurudzirwa kushandisa tambo terminals uye manual crimping terminal pliers.Kune akawanda-strand waya akakura kupfuura 16 square metres, zvinokurudzirwa kushandisa yakakosha terminals ye hydraulic clamps.

2. Insulation Layer

Rudzi rwerabha kunze kwewaya ndiyo insulation layer yewaya.Basa rayo nderekuparadzanisa conductor ane simba kubva kunze kwenyika, kudzivirira simba remagetsi kubva kuyerera kunze, uye kudzivirira vanhu vekunze kubva mukuvhunduka kwemagetsi.Kazhinji, nzira nhatu dzinotevera dzinogona kushandiswa kutonga kunaka kweiyo insulating layer:

1) Bata, bata pamusoro peiyo insulating layer zvishoma nemaoko ako.Kana iyo nzvimbo yakashata, inoratidza kuti kugadzirwa kweiyo insulating layer haina kunaka uye inowanzoitika kune zvikanganiso senge kudonha kwemagetsi.Dzvanya iyo insulating layer nechigunwe chako, uye kana ichikwanisa kudzoka nekukurumidza, inoratidza kuti iyo insulating layer ine hupamhi hwepamusoro uye kusimba kwakanaka.

2) Bend, tora chidimbu chewaya, uipete shure uye mberi kakawanda, uye wozoruramisa waya kuti uone.Kana pasina tsananguro pamusoro wewaya, zvinoratidza kuti waya ine nani kuoma.Kana iyo pamusoro pewaya iine indentation iri pachena kana kuchena kwakakomba, zvinoratidza kuti waya ine kuoma kwakashata.Kuvigwa muvhu kwenguva yakareba, zviri nyore kuchembera, kuita brittle, uye nyore kudonhedza magetsi mune ramangwana.

3) Kupisa.Shandisa mwenje kuti urambe uchipfuta pawaya kusvikira waya yekuvharisa yabata moto.Wobva wadzima renji uye wotanga kuita nguva-kana waya inogona kudzimwa yega mukati memasekondi mashanu, zvinoratidza kuti waya ine yakanaka retardancy.Zvikasadaro, zvinoratidzwa kuti murazvo unodzoreredza kugona kwewaya hausi kusvika pachiyero, dunhu rakaremerwa kana dunhu riri nyore kukonzera moto.

3. Photovoltaic System Wiring Skills

Mutsara we photovoltaic system yakakamurwa kuita DC chikamu uye AC chikamu.Izvi zvikamu zviviri zvemutsara zvinoda kuparadzaniswa zvakasiyana.Iyo DC chikamu chakabatana kune zvikamu, uye iyo AC chikamu chakabatana kune grid.Kune akawanda tambo dzeDC muzviteshi zvemagetsi zvepakati nepakati.Kuti zvive nyore kugadzirisa mune ramangwana, nhamba dzewaya dzetambo dzinofanira kusungirirwa.Kuparadzanisa waya dzakasimba uye dzisina simba.Kana paine waya dzechiratidzo, dzifambise zvakasiyana kuti usakanganiswa.Izvo zvinodikanwa kugadzirira tambo dzepombi uye mabhiriji, edza kusafumura waya, uye waya dzakachinjika uye dzakamira dzinotaridzika zviri nani kana dzichifambiswa.Edza kusave nemajoini etambo mumapombi eshinda uye mabhiriji, nekuti kuchengetedza hakuna kunaka.

Mune photovoltaic systems, mapurogiramu epamba uye zviduku zvemabhizimisi uye zvekutengeserana, simba re inverter riri pasi pe20kW, uye nzvimbo yemuchinjikwa yetambo imwe iri pasi pe10 square.Inokurudzirwa kushandisamulti-core solar cables.Panguva ino, hazvina kuoma kuisa uye nyore kubata;Simba rekushandura riri pakati pe20-60kW, uye nzvimbo yepamuchinjikwa yetambo imwe chete inopfuura 10 square uye pasi pe 35 square, iyo inogona kusarudzwa maererano nemamiriro ezvinhu epaiti;kana simba re inverter rinopfuura 60 kW uye nzvimbo ye-cross-sectional yetambo imwe chete inopfuura 35 square, zvinokurudzirwa kusarudza Single-core cables zviri nyore kushanda uye zvinodhura mumutengo.
