Ungawakhetha kanjani amaCable Photovoltaic for Photovoltaic Systems?

Intengo yethusi inyukile muva nje, nentengo yezintambo nayo yenyukile.Ezindlekweni eziphelele zezinhlelo ze-photovoltaic, izindleko zezesekeli ezifanaizintambo ze-photovoltaicfuthi amaswishi adlule lawo ama-inverter, futhi aphansi kuphela kunezingxenye nezisekelo.Uma sithola umdwebo wenkampani yokuklama futhi sazi imingcele yohlobo lwezintambo, ukujiya, umbala, njll., singaqala ukuthenga ngohlu.Kodwa-ke, kunezinhlobo eziningi zezintambo, futhi abasebenzisi abaningi bayamangala ngezinhlobo eziningi zezintambo.Iyiphi engcono?

Uma sikhetha ikhebula le-photovoltaic, kufanele siqale sibheke izici ezimbili: umqhubi kanye nesendlalelo se-insulating.Uma nje lezi zingxenye ezimbili zilungile, ikhwalithi yocingo ifakazelwa ukuthi ithembekile.

1. Umqhubi

Hlubula i-insulation yekhebula ukuze uveze ucingo lwethusi ngaphakathi, lona umqhubi.Singahlulela ikhwalithi yamakhondatha ngemibono emibili:

01. umbala

Nakuba abaqhubi bonke bebizwa ngokuthi "ithusi", abayona i-100% yethusi ehlanzekile, futhi kuyoba khona ukungcola okuthile kubo.Ukungcola okuningi okuqukethwe, kubi kakhulu ukuqhutshwa komqhubi.Inani lokungcola eliqukethwe ku-conductor ngokuvamile lizobonakala embala.

I-copper yekhwalithi engcono kakhulu ibizwa ngokuthi "ithusi elibomvu" noma "ithusi elibomvu" -njengoba igama libonisa, umbala walolu hlobo lwethusi unobomvu, u-purplish, obomvu-obomvu, obomvu obumnyama.

Uma ithusi liba libi kakhulu, umbala walo ulula futhi liphuzi ngokwengeziwe, okubizwa ngokuthi “ithusi.”Enye ithusi iphuzi ngokukhanyayo-ukungcola kwaleli thusi sekuvele kuphezulu kakhulu.

Ezinye zazo zimhlophe, lezi yizintambo ezithuthuke kakhulu.Izintambo zethusi zifakwe ungqimba lwethini, isizathu esiyinhloko ukuvimbela ithusi kusuka ku-oxidizing ukuze kwakhiwe i-patina.I-conductivity ye-patina impofu kakhulu, okwandisa ukumelana nokushisa kokushisa.Ukwengeza, izintambo zethusi zokucwenga zingavimbela futhi irabha yokufaka ekunamatheleni, ekubeni mnyama kanye nokuba brittleness komnyombo, kanye nokwenza ngcono ukudayiswa kwayo.Izintambo ze-Photovoltaic DC ziyizintambo zethusi ezithayiwe.

02. ukujiya

Uma ububanzi bocingo bufana, umqhubi we-conductor mkhulu, ukuqina kwe-conductivity-uma uqhathanisa ubukhulu, umqhubi kuphela okufanele aqhathaniswe, futhi ubukhulu bengqimba yokushisa akufanele kwengezwe.

Zama ukusebenzisa izintambo eziningi zocingo oluguquguqukayo.Kunentambo eyodwa kuphela ewumgogodla kukhebula, ebizwa nge-single core wire, njenge-BVR-1*6;kunezintambo eziningi eziyinhloko kukhebula, njenge-YJV-3*25+1*16, Ibizwa ngokuthi i-multi-core wire;intambo ngayinye ewumgogodla yakhiwe izintambo eziningi zethusi futhi ibizwa ngokuthi i-multi-strand wire, ethambile futhi efanelekile kumasistimu we-photovoltaic.Intambo enomucu owodwa ingacindezelwa ngokuqondile kutheminali, kodwa intambo enentambo eyodwa iqinile futhi ayifanele ukufakwa ezindaweni ezinobubanzi obuncane bokujika.Ezintanjeni ezinezintambo eziningi ezincane kuno-16 square metres, kunconywa ukuthi usebenzise amatheminali ekhebula kanye nodlawu lwemishini yokugenca.Ngezintambo ezinama-multi-strand ezinkulu kunamamitha-skwele angu-16, kunconywa ukusebenzisa amatheminali akhethekile ama-clamp hydraulic.

2. I-Insulation Layer

Ungqimba lwerabha ngaphandle kocingo luwungqimba olufakwayo lwentambo.Umsebenzi wayo ukuhlukanisa i-conductor enamandla ezweni langaphandle, ukuvimbela amandla kagesi ukuthi angagelezi ngaphandle, nokuvimbela abantu bangaphandle ekutholeni ukushaqeka kukagesi.Ngokuvamile, izindlela ezintathu ezilandelayo zingasetshenziswa ukwahlulela ikhwalithi ye-insulating layer:

1) Thinta, thinta ingaphezulu lesendlalelo se-insulating kalula ngezandla zakho.Uma ingaphezulu liqinile, lifakazela ukuthi inqubo yokukhiqiza ye-insulating layer impofu futhi ijwayele ukuba namaphutha njengokuvuza kukagesi.Cindezela isendlalelo se-insulating ngozipho lwakho, futhi uma lungabuyela emuva ngokushesha, kufakazela ukuthi ungqimba oluvikelayo lunogqinsi oluphezulu kanye nokuqina okuhle.

2) Goba, thatha ucezu locingo, ulugobise emuva naphambili izikhathi eziningana, bese uqondisa ucingo ukuze lubukwe.Uma kungekho mkhondo ebusweni bocingo, kufakazela ukuthi ucingo lunokuqina okungcono.Uma ingaphezulu lentambo linokuhlehla okusobala noma libe mhlophe okungathi sína, kufakazela ukuthi intambo inokuqina okubi.Njengoba ingcwatshwe phansi isikhathi eside, kulula ukuguga, iba brittle, futhi kulula ukuvuza ugesi esikhathini esizayo.

3) Shisa.Sebenzisa okokukhanyisa ukuze uqhubeke uvutha ocingweni kuze kube yilapho i-insulation yocingo ibamba umlilo.Bese ucisha okokulula futhi uqale ukubeka isikhathi-uma intambo ingacisha ngokuzenzakalelayo phakathi kwamasekhondi angu-5, kufakazela ukuthi intambo inokubambezeleka okuhle kwelangabi.Uma kungenjalo, kufakazelwa ukuthi ikhono lokubuyisela ilangabi locingo alikho ezingeni elijwayelekile, isifunda sigcwele kakhulu noma isifunda kulula ukubangela umlilo.

3. I-Photovoltaic System Wiring Amakhono

Umugqa wesistimu ye-photovoltaic uhlukaniswe ingxenye ye-DC kanye nengxenye ye-AC.Lezi zingxenye ezimbili zomugqa zidinga ukuhlukaniswa ngezintambo.Ingxenye ye-DC ixhunywe ezingxenyeni, futhi ingxenye ye-AC ixhunywe kugridi.Kunezintambo eziningi ze-DC eziteshini zikagesi eziphakathi nendawo nezinkulu.Ukuze kube lula ukulungiswa kwesikhathi esizayo, izinombolo zezintambo zezintambo kufanele ziboshwe.Hlukanisa izintambo eziqinile nezibuthakathaka.Uma kunezintambo zesignali, zihambise ngokuhlukana ukuze ugweme ukuphazamiseka.Kudingekile ukulungisa amapayipi namabhuloho okuthungatha, zama ukungavezi izintambo, futhi izintambo ezivundlile neziqondile zizobukeka kangcono uma zihanjiswa.Zama ukuthi ungabi namajoyinti ekhebula kumapayipi okuthungatha kanye namabhuloho, ngoba ukunakekela akulula.

Ezinhlelweni ze-photovoltaic, amaphrojekthi asendlini kanye namaphrojekthi amancane ezimboni nezentengiselwano, amandla e-inverter angaphansi kwe-20kW, futhi indawo ephambanayo yekhebula elilodwa ingaphansi kwezikwele eziyi-10.Kunconywa ukusebenzisaizintambo eziningi zelanga.Ngalesi sikhathi, akunzima ukubeka futhi kulula ukuphatha;Amandla okuguqula aphakathi kuka-20-60kW, futhi indawo ye-cross-sectional yekhebula elilodwa ingaphezu kwezikwele ezingu-10 futhi ingaphansi kwezikwele ezingu-35, ezingakhethwa ngokuvumelana nezimo zesayithi;uma amandla e-inverter engaphezu kuka-60 kW futhi indawo ye-cross-sectional yekhebula elilodwa ingaphezu kwezikwele ezingu-35, kunconywa ukuba ukhethe izintambo ze-Single-core zisebenza kalula futhi zishibhile ngentengo.
