Indlela yokukhetha iiCables Photovoltaic kwiiNkqubo zePhotovoltaic?

Ixabiso lobhedu liye lanyuka mva nje, kwaye ixabiso leentambo liye lanyuka.Kwixabiso elipheleleyo leenkqubo ze-photovoltaic, iindleko zezixhobo ezifanaiintambo ze-photovoltaickwaye iiswitshi zigqithile kwezo ze-inverters, kwaye zingaphantsi kuphela kumacandelo kunye nezixhaso.Xa sifumana umzobo wenkampani yokuyila kwaye siyazi iiparameters zohlobo lwecingo, ubukhulu, umbala, njl., sinokuqala ukuthenga ngoluhlu.Nangona kunjalo, zininzi iintlobo zeengcingo, kwaye abasebenzisi abaninzi badidekile ziintlobo ezininzi zeengcingo.Yeyiphi engcono?

Xa ukhetha ikhebula le-photovoltaic, kufuneka siqale sijonge iinkalo ezimbini: umqhubi kunye ne-insulating layer.Ngethuba nje ezi nxalenye zimbini zilungile, umgangatho wocingo ubonakaliswe ukuba uthembekile.

1. Umqhubi

Ukuqhawula i-insulation yekhebula ukuveza ucingo lobhedu ngaphakathi, lo ngumqhubi.Sinokuwugweba umgangatho wabaqhubi kwiimbono ezimbini:

01. umbala

Nangona abaqhubi bonke babizwa ngokuthi "ubhedu", abayi-100% yethusi ecocekileyo, kwaye kuya kubakho ukungcola kubo.Ukungcola okungaphezulu kuqulethwe, kubi ngakumbi ukuqhuba komqhubi.Ubuninzi bokungcola okuqulethwe kumqhubi uya kubonakala ngokubanzi kumbala.

Ubhedu olusemgangathweni lubizwa ngokuba "ubhedu obomvu" okanye "ubhedu obomvu" -njengoko igama libonisa, umbala wolu hlobo lobhedu unobomvu, obomvu, obomvu-obomvu, obomvu obumnyama.

Okukhona ubhedu lusiba lubi, kokukhona umbala ukhaphukhaphu kwaye utyheli ngakumbi, nto leyo ebizwa ngokuba “lubhedu.”Olunye ubhedu lutyheli olukhanyayo-ukungcola kolu bhedu sele kuphezulu kakhulu.

Ezinye zazo zimhlophe, ezi ziingcingo ezihamba phambili.Iingcingo zobhedu zifakwe ngoluhlu lwe-tin, isizathu esiyintloko kukuthintela ubhedu kwi-oxidizing ukwenza i-patina.I-conductivity yepatina ihlupheke kakhulu, eyandisa ukuxhathisa kunye nokutshatyalaliswa kobushushu.Ukongeza, ukuthambisa iingcingo zobhedu kunokuthintela irabha yokugquma ukuba ingancamatheli, ibe mnyama kwaye ibe brittleness yombindi, kunye nokuphucula ukuthengiseka kwayo.Iintambo ze-Photovoltaic ze-DC ziziintambo zobhedu ezinkonkxiweyo.

02. ubukhulu

Xa i-diameter ye-wire ifana, i-conductor iyanda, i-conductivity yomelele-xa kuthelekiswa nobukhulu, kufuneka kuthelekiswe kuphela umqhubi, kwaye ubukhulu bomgangatho we-insulating akufanele bongezwe.

Zama ukusebenzisa imicu emininzi yocingo olubhetyebhetye.Kukho intambo enye kuphela kwintambo, ebizwa ngokuba yi-single core wire, njenge-BVR-1 * 6;kukho iingcingo ezingundoqo ezininzi kwintambo, njenge-YJV-3 * 25 + 1 * 16, Ibizwa ngokuba yi-multi-core wire;ucingo ngalunye olungundoqo luqulunqwe ngeengcingo ezininzi zobhedu kwaye lubizwa ngokuba yi-multi-strand wire, ethambileyo kwaye ifanelekile kwiinkqubo ze-photovoltaic.I-wire-stranded wire ingaba crimped ngokuthe ngqo kwi-terminal, kodwa i-wire-stranded wire inzima kwaye ayifanelekanga ukufakwa kwiindawo ezine-radius encinci yokujika.Kwiintambo ezininzi ezincinci kuneemitha ezili-16 zesikwere, kuyacetyiswa ukuba usebenzise i-terminal terminals kunye ne-manual crimping terminal pliers.Kwiintambo ezininzi ze-strand ezinkulu kune-16 square metres, kucetyiswa ukuba kusetyenziswe i-terminals ezikhethekileyo kwii-clamps ze-hydraulic.

2. I-Insulation Layer

Umaleko werabha ngaphandle kocingo ngumaleko wokugquma wocingo.Umsebenzi wayo kukwahlula umqhubi onamandla kwilizwe langaphandle, ukuthintela amandla ombane ukuba aphume ngaphandle, kwaye uthintele abantu bangaphandle ukuba bafumane ukothuka kombane.Ngokubanzi, ezi ndlela zintathu zilandelayo zingasetyenziselwa ukugweba umgangatho womgangatho wokukhusela:

1) Chukumisa, chukumisa umphezulu we-insulating layer ngezandla zakho.Ukuba ubuso bunzima, bubonisa ukuba inkqubo yokuvelisa i-insulating layer ihlwempuzekile kwaye ixhomekeke kwiimpazamo ezifana nokuvuza kombane.Cinezela umaleko wokugquma ngomnwe wakho, kwaye ukuba unokuphinda ubuyele ngokukhawuleza, ungqina ukuba umaleko wokugquma unobunzima obuphezulu kunye nokuqina okuhle.

2) Goba, thabatha isiqwenga socingo, ugobe ngasemva naphambili amaxesha amaninzi, uze ulungelelanise ucingo ukuze uqwalaselwe.Ukuba akukho mkhondo ebusweni bocingo, kubonisa ukuba ucingo lunobunzima obungcono.Ukuba umphezulu wocingo une-indentation ecacileyo okanye ubumhlophe obunzulu, bubonisa ukuba ucingo lunobunzima obunzima.Ukungcwatywa emhlabeni ixesha elide, kulula ukuguga, ukuba brittle, kwaye kulula ukuvuza umbane kwixesha elizayo.

3) Tshisa.Sebenzisa into yokulayita ukuze uhlale uvutha ecingweni de isigqubuthelo socingo sivuthe umlilo.Emva koko cima i-lighter kwaye uqalise ixesha-ukuba ucingo lunokucima ngokuzenzekelayo ngaphakathi kwemizuzwana emi-5, kubonisa ukuba ucingo lunomlilo onqabileyo.Ngaphandle koko, kubonakaliswe ukuba i-flame retardant ikhono locingo alikho kumgangatho, isiphaluka sigcwele kakhulu okanye isiphaluka kulula ukubangela umlilo.

3. I-Photovoltaic System Wiring Skills

Umgca wenkqubo ye-photovoltaic ihlukaniswe yaba yinxalenye ye-DC kunye nenxalenye ye-AC.Ezi nxalenye zimbini zomgca kufuneka zifakwe ngokwahlukileyo.Inxalenye ye-DC idibaniswe kumacandelo, kwaye inxalenye ye-AC ixhunyiwe kwigridi.Zininzi iintambo zeDC kwizikhululo zamandla eziphakathi nezinkulu.Ukuze kuququzelelwe ukugcinwa kwexesha elizayo, iinombolo zeengcingo zeentambo kufuneka zifakwe.Yahlula iingcingo ezomeleleyo nezibuthathaka.Ukuba kukho iingcingo zomqondiso, zihambise ngokwahlukeneyo ukuphepha ukuphazamiseka.Kuyimfuneko ukulungiselela imibhobho yokucoca kunye neebhulorho, zama ukungavezi iingcingo, kwaye iingcingo ezithe tye kunye nezithe nkqo ziya kubonakala zibhetele xa zihanjiswa.Zama ukungabi namalungu ekhebula kwimibhobho yokucoca kunye neebhuloho, kuba ukugcinwa kungenakulungeleka.

Kwiinkqubo ze-photovoltaic, iiprojekthi zendlu kunye neeprojekthi ezincinci zoshishino kunye nezorhwebo, amandla e-inverter angaphantsi kwe-20kW, kwaye indawo enqamlezayo yekhebula enye ingaphantsi kwe-square ye-10.Kucetyiswa ukusebenzisaiintambo ezininzi zelanga.Ngeli xesha, akunzima ukubeka kwaye kulula ukulawula;Amandla okuguqula aphakathi kwe-20-60kW, kunye nommandla we-cross-sectional wekhebula elilodwa lingaphezulu kwe-square ye-10 kunye ne-square ye-35, enokuthi ikhethwe ngokwemiqathango yesayithi;ukuba amandla e-inverter angaphezulu kwe-60 kW kunye nommandla we-cross-sectional wekhebula elilodwa lingaphezu kwe-35 square, kuyacetyiswa ukuba ukhethe iintambo ze-Single-core zilula ukusebenza kwaye zingabizi kwixabiso.
