Raws li qhov kev thov ntawm qhov project photovoltaic, aluminium alloy cable kab yuav tsum tau ua kom muaj kev nyab xeeb ntawm txoj haujlwm, ua kom yooj yim txij nkawm, thiab ua tib zoo xav txog hauv av ib puag ncig, cov ntaub ntawv hauv av thiab ntau qhov chaw hauv av, kom txo tau kev siv cov cables, txuag cov nqi, thiab txo qhov poob thiab reactive zog tshwm sim los ntawm cables.Cov kev cai ua ntej yog raws li nram no:
1) Txhim kho kev siv cov txhuas hnub ci cables, xaiv txoj kev luv tshaj plaws, txo qhov poob thiab txuag nqi.
2) Npaj txoj kev cable raws li tag nrho kom txo tau rov qab khawb ntawm cable trench;
3) Txo tus naj npawb ntawm cov kav xa hluav taws xob, kev tsheb ciav hlau thiab lwm lub zog hluav taws xob, thiab txo cov phab ntsa hla thiab cov plag tsev;
4) Txo qhov kev puas tsuaj rau cov kab hluav taws xob los ntawm ib puag ncig, thiab tiv thaiv lub cable los ntawm kev cuam tshuam los ntawm cov khoom siv sab nraud, tshuaj lom neeg corrosion, kev co, thiab hauv av;
5) Cov dej ntws tawm, cov kav dej roj, cov kav dej loj, cov kab tsis muaj zog, thiab lwm yam yog muab rau ntawm ib sab ntawm txoj kev, thiab lub hwj chim cable yuav tsum tau muab tso rau ntawm lwm sab ntawm txoj kev.
Muaj qee qhov teeb meem hauv kev tsim cov AC terminals ntawm qhov project site, feem ntau:
1) Cov terminals txuas tsis sib xws
Qhov teeb meem tseem ceeb tshaj plaws nyob rau hauv kev txhawb nqa hauv tsev thiab kev siv cov khoom siv hluav taws xob aluminium yog qhov sib txuam txuas yog qhov nyuaj rau kev yuav khoom.Yog li ntawd, qee qhov chaw siv tooj liab-aluminium hloov terminals lossis lwm yam hlau txuas uas tsis sib xws rau kev ua haujlwm ntawm aluminium alloy cables.Xws li kev siv tsis tuaj yeem lav qhov kev nyab xeeb ntawm kev siv cov cables thiab yuav ua rau muaj kev phom sij zais cia.
2) Qhov loj ntawm lub davhlau ya nyob twg tsis sib haum
Tam sim no, feem ntau lub hwj chim terminals, nrog rau tag nrho cov txheej txheem ntawm hluav taws xob tsim, txais yuav tooj liab cable specifications thiab loj cov qauv.Aluminium cables los yogaluminium alloy cablestxawv ntawm cov tooj liab cables vim lawv lub peev xwm nqa tam sim no.Thaum siv, qhov chaw hla ntu yog nce ntxiv kom ua tau raws li qhov yuav tsum tau nqa tam sim no, uas ua rau lub cable tsis sib haum nrog qhov loj ntawm lub qhov hluav taws xob qub.Tam sim no, txoj hauv kev zoo tshaj plaws yog hloov cov tooj liab tuav, los yog hnav lossis txiav tawm ib feem ntawm tus neeg xyuas pib kom txo tau qhov chaw hla ntu.Ob txoj kev no yuav ua rau muaj kev phom sij ntau dua.
3) Irregular crimping thaum lub sij hawm installation
Nyob rau hauv tus txheej txheem ntawm kev sib txuas lus nrog EPC manufacturers, kuv feem ntau hnov cov lus hais tias "Lub installation thiab kev tsim kho ntawm txhuas cables los yog aluminium alloy cables yuav tsum tau ua los ntawm tej yam electricians", vim hais tias ib qho chaw uas tsis pom thaum lub sij hawm tsim kho tej zaum yuav tshwm sim. , qhov chaw nres tsheb fais fab tsis tuaj yeem ua haujlwm tau zoo thiab nyab xeeb.Nyob rau tib lub sijhawm, rau kev siv "txhuas cables thiab aluminium alloy cables yuav tsum siv cov cuab yeej tshaj lij, tsis tuaj yeem ua haujlwm raws li cov txheej txheem ntawm cov tooj liab cables", cov ntsiab lus txuas ntxiv yuav piav qhia txog cov txheej txheem ntawm aluminium alloy cables hauv kev nthuav dav. .
Los ntawm cov lus piav qhia ntawm cov kev phom sij zais, xaiv txoj cai txuas txuas rau txhuas lossis aluminium alloy cable yog thawj kauj ruam los txhawb kev ua haujlwm cable.Tam sim no, muaj peb hom terminals nyob rau hauv kev ua lag luam haum rau txhuas alloy cables, xws li tooj liab terminals, tooj liab-aluminium hloov terminals thiab aluminium alloy tooj liab hloov terminals.
a. tooj liab davhlau ya nyob twg: Nws yog lub davhlau ya nyob twg ntau tshaj plaws, tab sis vim yog electrochemical corrosion ntawm tooj liab thiab txhuas thiab lub cev tsis sib xws thiab cov khoom siv kho tshuab, yuav muaj qee yam kev phom sij hauv qhov zoo ntawm cov haujlwm photovoltaic.
b. Copper-Aluminium Transition Terminal: Nws yog dav siv dav dav rau txhuas cables thiab aluminium alloy cables.Lub davhlau ya nyob twg yog tsim los ntawm ob qhov chaw, ib qho kawg yog siv los txuas cov txhuas hlau thiab aluminium alloy cable, thiab lwm yam yog txhawm rau txuas ua tiav cov khoom siv hluav taws xob lossis lwm lub hwj chim terminals, cov tooj liab-aluminium hloov terminals tau muab faib ua DTL- 1, DTL-2 thiab tus pin-hom tooj liab-aluminium raj raws li lawv cov duab.
Nyob rau tib lub sijhawm, qee qhov chaw tsim khoom lag luam coj mus rau hauv tus account qhov sib txawv ntawm cov khoom siv hluav taws xob ntawm tooj liab, aluminium thiab aluminium alloys, thiab yuav siv cov khoom siv coj mus rau lub raj txhuas.Txoj kev no tuaj yeem txo qhov corrosion ntawm aluminium raj.
Kev sib txuas ntawm cable nruab nrab thiab lub davhlau ya nyob twg ncaj qha cuam tshuam rau kev ntseeg tau ntawm tag nrho cov kab ke.Hauv qee qhov haujlwm, cov cuab yeej kev tshaj lij tsis siv rau kev crimping ntawm aluminium alloy cables, uas ua rau muaj kev nyab xeeb zais zais lossis teeb meem hauv qhov project.
