       Mosebetsi oa leloala la ho roala ke ho hlahisa marapo a koporo a pharaletseng le a bataletseng ka li-rolls tse hlophisitsoeng (tse entsoeng ho ea ka bophara ba stack), ha li ntse li felisa li-burrs tse hlahisoang nakong ea ts'ebetso ka mochine oa ho sila; The "taolo ea mocheso" ea leloala rolling (koporo hlobolisa mocheso ≤ 60 ℃ nakong rolling) ka thibela kgolo ya koporo hlobolisa lijo-thollo, etsa bonnete ba hore matla a eona a mechine (tensile matla ≥ 200MPa), 'me ikamahanya le ho sebetsa ka nako e telele ea mokelikeli phallo mekotla ea betri (moralo oa bophelo ba lilemo tse fetang 20).

2,Boemo bo atolositsoeng ba ts'ebeliso: Likarolo tse tsamaisang tsa kantle tsa sistimi ea polokelo ea matla

        Ntle le likhokahano tsa kahare ka har'a betri, likhoele tse nepahetseng tsa koporo tse hlahisoang ke li-mill tsa photovoltaic li ka boela tsa sebelisoa bakeng sa "likhokahanyo tsa conductive tsa kantle" lits'ebetsong tsa polokelo ea matla joalo ka lijana tsa polokelo ea matla le likhabinete tsa polokelo ea matla a ntlo, ho rarolla bothata ba ho ikamahanya le maemo a likarolo tse tloaelehileng tsa conductive joalo ka likhoele le mekoallo ea koporo libakeng tse kopaneng.

1. "Flexible conductive strip" bakeng sa module ea polokelo ea matla le inverter

        Litlhoko tsa kopo: Lijaneng tsa polokelo ea matla, sebaka sa ho hokahanya pakeng tsa li-modules tsa betri (haholo-holo li patiloe ka holimo) le li-inverters li moqotetsane, 'me mekoallo e tloaelehileng ea koporo e thata (e thata, e seng bonolo ho e koba) ho thata ho e kenya. Ho hlokahala "flexible conductive strip" (e phutholohang, e kobehang) ho fihlela khokahano. Litlhoko tsa eona ke:

        Botenya ba 0.1-0.2mm, bophara ba 10-30mm (e etselitsoeng ho latela boholo ba hona joale, joalo ka 200A hona joale e lumellanang le 20mm bophara ba koporo);

        E ka bokelloa ka mekhahlelo e mengata (joalo ka likotoana tse 3-5 tsa lithupa tsa koporo tse pakoang ho matlafatsa bokhoni ba hona joale ba ho jara);

        Sekoaelo sa ho kenella ka holim'a metsi se na le sekhomaretsi se matla (se hloka ho koaheloa ka sekoaelo ka mor'a ho roala ha koporo ho qoba potoloho e khuts'oane).

        Mosebetsi oa leloala le roalang: Lesela le tšesaane la koporo le hlahisoang le na le sephara se phahameng (ha ho na sebopeho sa maqhubu), se ka netefatsang ho kopana ho thata ha likarolo tse ngata li kenngoa (ha ho lekhalo, ho fokotsa ho hanyetsa ho kopana); "Ts'ebetso e tsoelang pele ea ho roala" ea leloala la ho roala e ka finyella tlhahiso ea li-coil tse telele tsa koporo (bolelele bo le bong ba coil ea 500-1000m), ho finyella litlhoko tsa kopano ea batch ea mekhoa ea ho boloka matla le ho nkela sebaka sa "stamping le ho itšeha" mokhoa oa ts'ebetso o hasaneng (ho eketsa katleho ka ho feta 30%).

2. "Lihokelo tse nyane tsa conductive" bakeng sa likhabinete tsa polokelo ea matla a ntlo

       Litlhoko tsa kopo: Khabinete ea polokelo ea matla ka tlung (bokhoni ba 5-20kWh) e na le molumo o monyenyane, 'me kamano pakeng tsa lisele tse ka hare tsa betri, BMS (mokhoa oa tsamaiso ea betri), le li-interfaces li hloka "li-micro conductive connectors". Hangata boholo ke 3-8mm ka bophara le 0.1-0.15mm ka botenya. Litlhoko:

       Mamello ea dimensional e nyane haholo (bophara ± 0.02mm, botenya ± 0.002mm) ho qoba ho kena-kenana le likarolo tse ling;

       E bobebe (e fokotsa boima ba kakaretso ea khabinete ea polokelo ea matla le ho thusa ho kenya).

       Mosebetsi oa leloala la ho roala ke ho hlahisa khoele e moqotetsane e nepahetseng ka "leloala le moqotetsane le bophara bo phahameng + taolo e nepahetseng ea servo", ebe o etsa likotoana tse kopanyang ka mekhoa e latelang ea ho petsola le tin; "Ho nepahala ha "rolling" ea leloala le bilikang ho ka etsa bonnete ba ho lumellana ha boholo ba poleiti e kopanyang (sekhahla sa ho feta ≥ 99.5%), ho qoba ho hlōleha ho kenya ho bakoang ke ho kheloha ha boholo (joalo ka ho kopana ho fokolang le ho sitoa ho kenya li-interfaces).

3,Melemo ea kopo: Ke hobane'ng ha indasteri ea polokelo ea matla e khetha photovoltaic welding le rolling Mills?

       Ha ho bapisoa le lisebelisoa tse tloaelehileng tsa tlhahiso ea tšepe tse kang mechine ea ho phunya le mechine e tloaelehileng ea ho roala, melemo ea kopo ea photovoltaic welding strip rolling Mills indastering ea polokelo ea matla e bonahala haholo-holo ka lintlha tse tharo:

       Ho nepahala ho nyalana: The mamello botenya (± 0.003-0.005mm) le bokaholimo holim (Ra ≤ 0.2 μ m) ea polokelo ea matla conductive strip e hlokehang ho lumellana le bophahamo ba photovoltaic tjheseletsa hlobolisa, ntle le tlhokahalo ea liphetoho tsa bohlokoa ho leloala la ho roala. Ho lokisa feela li-parameter tsa rolling (tse kang lekhalo le lebelo) ho ikamahanya le maemo;

       Molemo oa litšenyehelo: "Ts'ebetso e tsoelang pele ea ho roala" ea photovoltaic strip rolling mills e ka finyella tlhahiso e kholo (ka matla a letsatsi le letsatsi a tlhahiso ea lithane tse 1-2 ka thepa). Ha ho bapisoa le "ts'ebetso ea nakoana" ea mechine ea litempe, theko ea sehlahisoa sa yuniti e fokotsehile ka 15% -20%, e finyellang litlhoko tsa mantlha tsa indasteri ea polokelo ea matla bakeng sa "phokotso ea litšenyehelo le ntlafatso ea katleho";

       Tšebelisano ea lintho tse bonahalang: E ​​ka tsamaisa lisebelisoa tse fapaneng tse kang koporo e hloekileng, motsoako oa koporo, koporo e entsoeng ka nickel, joalo-joalo, ho finyella litlhoko tsa conductivity tsa libeteri tse fapaneng tsa polokelo ea matla (joaloka koporo e hloekileng bakeng sa lithium iron phosphate le alloy ea koporo bakeng sa libeteri tse phallang), ntle le tlhokahalo ea ho nkela thepa ea mantlha sebaka.
