Yuav Ua Li Cas Hlau Hnub Ci Vaj Huam Sib Luag Junction Box?

   Solar vaj huam sib luag hlws ris thawvyog ib qho tseem ceeb tab sis yooj yim overlooked ib feem ntawm PV modules.Lub hnub ci hlws ris lub thawv yog ib qho thaiv ntawm PV module siv los txuas PV cov hlua thiab feem ntau yog pre-installed rau sab nraum qab ntawm lub hnub ci vaj huam sib luag los tiv thaiv PV module los ntawm ib puag ncig.Niaj hnub no feem ntau photovoltaic hlws ris lub thawv manufacturers nyob hauv Suav teb, thiab Slocable yog ib lub npe nrov PV hlws ris lub thawv manufacturers hauv Dongguan, Suav.

Hnub ci vaj huam sib luag Junction Box txuas rau PV Module li cas?

Lub hnub ci vaj huam sib luag lub thawv txuas nrog rau sab nraum qab ntawm lub hnub ci vaj huam sib luag (TPT) los ntawm silicone nplaum, nws txuas 4 PV connectors ua ke thiab yog qhov tso zis interface ntawm lub hnub ci vaj huam sib luag.

Yuav Ua Li Cas Txuas Ib Lub Hnub Ci Junction Box rau PV Array?

Txuas lub hnub ci vaj huam sib luag rau cov array yog ua kom yooj yim los ntawm kev siv lub thawv hnub ci hleb.Feem ntau siv lub cable nrog MC4 connector ntawm qhov kawg.

Ib lub hnub ci vaj huam sib luag zoo yuav txo qis corrosion ntawm cov terminals vim nws yuav ua kom dej tawm.Thaum muas lub hnub ci modules, nco ntsoov xyuas tus IP ntsuam xyuas ntawm lub hnub ci hlws ris lub thawv, lub thawv dej tsis muaj dej puv yog cim nrog IP67 / IP68.

Hnub Ci Vaj Huam Sib Luag Junction Box Basics

Lub hnub ci vaj huam sib luag lub thawv muaj bypass diodes uas ua kom lub zog ntws mus rau hauv ib qho kev coj thiab tiv thaiv nws los ntawm kev pub rov qab rau lub hnub ci vaj huam sib luag.Frank Rosenkranz, tus thawj tswj xyuas khoom hnub ci rau EMEA, Is Nrias teb thiab Asmeskas ntawm lub hnub ci kev sib txuas lub thawv thiab cov chaw tsim khoom TE Connectivity, piav qhia lub thawv sib txuas ua "qhov tseem ceeb tshaj plaws ntawm lub hnub ci vaj huam sib luag."

"Txhua txoj hlua PV tiv thaiv los ntawm diodes hauv lub thawv sib txuas," nws hais."Diodes yog lub rooj vag uas tso cai rau lub zog tsis muaj kev cuam tshuam."

Yog hais tias ib feem ntawm lub hnub ci vaj huam sib luag yog ntxoov ntxoo, PV txoj hlua yuav tsum tau siv lub zog, thim rov qab lub zog ntws.Diodes hauv lub hnub ci hlws ris lub thawv tiv thaiv qhov no los ntawm qhov tshwm sim.

Muaj ob txoj hauv kev sib txawv ntawm lub hnub ci hlws ris lub thawv tsim khoom - soldering / potting thiab clamping.Siv cov txheej txheem soldering thiab potting, cov ntawv ci tawm los ntawm lub hnub ci vaj huam sib luag yog soldered rau lub diode hauv lub thawv sib txuas.Tom qab ntawd lub thawv sib txuas yuav tsum tau muab tso rau hauv lub lauj kaub los yog ntim nrog cov khoom nplaum kom tso cai rau kev hloov pauv ntawm cov cua sov, tuav cov pob qij txha hauv qhov chaw thiab tiv thaiv lawv los ntawm kev ua tsis tiav.Thaum txaus lub sij hawm dhau mus rau cov khoom siv potting kom kho tag nrho, lub hnub ci vaj huam sib luag yog npaj rau kev siv.

Los ntawm clamping ntau lawm, ib qho yooj yim clamping mechanism txuas cov ntawv ci rau cov hlau.Tsis muaj pa taws thiab tsis muaj kev ntxuav loj xws li cov txheej txheem soldering / potting.Thaum sib piv cov khoom siv thiab cov nqi ua haujlwm tag nrho, ob txoj hauv kev yog qhov sib npaug ntawm tus nqi.Lub thawv clamping tuaj yeem kim dua, tab sis kev ua haujlwm yuav tsum tau ua rau solder thiab lub lauj kaub rau lwm lub thawv yuav siab dua.
