Dab tsi yog Combiner Box
Lub thawv sib txuas, tseem hu ua lub thawv hnub ci sib txuas lossis lub thawv sib txuas, yog ib qho tseem ceeb hauv kev tsim hluav taws xob photovoltaic (PV) tshuab. Nws pab txhawb kev sib txuas thiab kev tiv thaiv ntawm ntau lub hnub ci vaj huam sib luag, cia lawv ua haujlwm ua ke kom zoo thiab nyab xeeb. Lub hom phiaj tseem ceeb ntawm lub thawv sib txuas yog ua ke cov zis ntawm ntau lub hnub ci vaj huam sib luag rau hauv ib qho kev tso zis, uas tom qab ntawd txuas nrog lub inverter rau lub zog hloov pauv mus rau lwm qhov tam sim no (AC).
Hom Confluence Boxes
Muaj ob lub ntsiab ntawm cov thawv sib txuas: cov hlua txuas cov thawv thiab cov thawv sib txuas sib txuas.
1. String Combiner Boxes: Cov thawv no yog tsim los tswj cov khoom tsim tawm ntawm ntau cov hlua PV, uas yog cov pab pawg ntawm cov hnub ci vaj huam sib luag txuas nrog hauv series. Lawv feem ntau suav nrog fuses lossis Circuit Court breakers rau txhua txoj hlua, muab kev tiv thaiv overcurrent thiab ua kom muaj kev nyab xeeb ntawm lub cev.
2. Array Combiner Boxes: Cov thawv no yog siv thaum muaj ntau yam PV arrays (pab pawg ntawm PV hlua) txuas nrog tib yam. Lawv muab cov zis ntawm tag nrho cov arrays rau hauv ib qho kev tso zis, ib yam li cov hlua sib txuas. Array combiner thawv kuj muaj kev tiv thaiv overcurrent rau txhua array.
Daim ntawv thov scenarios ntawm lub thawv Combiner
Cov thawv sib txuas yog siv rau hauv ntau lub hnub ci PV kev teeb tsa, suav nrog thaj chaw nyob, kev lag luam, thiab kev siv hluav taws xob. Lawv yog qhov tseem ceeb hauv txhua qhov system nrog ntau lub hnub ci vaj huam sib luag, vim tias lawv pab tswj kom muaj qhov sib npaug thiab cov theem tam sim no, txhim kho kev ua haujlwm zoo, thiab ua kom muaj kev nyab xeeb ntawm tag nrho cov kab ke.
Yuav Ua Li Cas Txuas Ib Lub Thawv Header rau PV Vaj Huam Sib Luag
Txhawm rau txuas lub thawv sib txuas rau PV panels, ua raws cov kauj ruam hauv qab no:
1. Txiav txim seb tus naj npawb ntawm cov hlua thiab arrays raws li qhov system loj thiab teeb tsa.
2. Txuas cov xov hlau zoo thiab tsis zoo ntawm txhua txoj hlua PV lossis array mus rau cov khoom siv sib txuas ntawm lub thawv sib txuas.
3. Xyuas kom meej tias txhua txoj hlua lossis array muaj kev tiv thaiv overcurrent (fuses lossis circuit breakers) ntsia rau hauv lub thawv sib txuas.
4. Txuas cov zis ntawm lub thawv sib txuas mus rau cov tswv yim terminals ntawm lub inverter.
Qhov sib txawv ntawm lub Box Combiner thiab Junction Box
Lub thawv sib txuas thiab lub thawv sib txuas ob leeg ua lub luag haujlwm tseem ceeb hauv lub hnub ci PV, tab sis lawv ua haujlwm sib txawv. Lub thawv sib txuas yog lub luag haujlwm rau kev sib txuas thiab tiv thaiv ntau lub hnub ci vaj huam sib luag, thaum lub thawv sib txuas feem ntau pom nyob rau sab nraum qab ntawm ib tus neeg lub hnub ci vaj huam sib luag. Lub thawv sib txuas yog lub luag haujlwm rau vaj tsev cov hluav taws xob sib txuas thiab diodes tsim nyog rau lub vaj huam sib luag ua haujlwm kom raug. Hauv qhov sib piv, lub thawv sib xyaw ua ke sib txuas cov zis ntawm ntau lub vaj huam sib luag thiab tiv thaiv lub kaw lus los ntawm overcurrents thiab lwm yam hluav taws xob tsis zoo.
