Lub hnub ci PV sib txuas lub thawv rau 4 txog 24 txoj hlua yog "qhov chaw nruab nrab" nyob nruab nrab ntawm PV module array thiab DC faib txee / inverter. Nws ua hauj lwm rau converge DC zog los ntawm ntau yam (4 mus rau 24) PV hlua rau hauv 1-2 tso zis circuits, thaum tib lub sij hawm muab kev tiv thaiv, saib xyuas, thiab kev sib txuas lus functions. Nws yog ib qho khoom siv tseem ceeb rau kev nyab xeeb thiab ua haujlwm tau zoo ntawm lub chaw nres tsheb fais fab.
Lub ntsiab Cheebtsam ntawm lub hnub ci PV combiner lub thawv
● Enclosure: Hlau vaj tse nrog lub zog siab thiab tiv thaiv- cov khoom siv corrosion.
● DC molded case Circuit Breaker (MCCB): Tsis siv neeg disconnects Circuit Court thaum tam sim no tshaj qhov txwv.
● DC Fuse: Muab kev tiv thaiv overcurrent los ntawm fusing, feem ntau siv NH00 hom.
● Anti-Rov qab Diode: Tiv thaiv kev thim rov qab tam sim no.
● Kev Tiv Thaiv Hluav Taws Xob Module SPD: Raws li Hlau Oxide Varistor (MOV) thev naus laus zis, muab cov kev tiv thaiv siab ib txwm thiab tsis tshua muaj kev tiv thaiv rau kev hloov pauv.
● Data Acquisition Module: Saib xyuas cov kev khiav hauj lwm tsis raws sij hawm.
● Terminal Blocks: Txhawb kev sib txuas ntawm ntau txoj hlua.
Lub hnub ci PV combiner lub thawv ua haujlwm li cas
Thaum nruab hnub, PV modules tsim DC lub zog → lub zog los ntawm txhua txoj hlua nkag mus rau hauv lub thawv sib txuas ntawm cov cables thiab dhau los ntawm fuses → converges mus rau lub busbar → yog tso tawm los ntawm DC Circuit Court breaker → thiab xa mus rau lub inverter.
In case of overcurrent or short circuit, the fuse blows or the circuit breaker trips. If a lightning strike induces a surge >1 kV ntawm kab, SPD ua tam sim ntawd, hloov tam sim no mus rau hauv av thiab clamping qhov voltage hauv qab 2 kV. Lub rooj saib xyuas tsis tu ncua sib piv cov nqi tam sim no thiab rwb thaiv tsev, qhia txog qhov txawv txav tam sim ntawd, ua tiav "observability, locatability, thiab isolatability."

Cov haujlwm tseem ceeb ntawm lub hnub ci PV ua ke lub thawv ua haujlwm
| Muaj nuj nqi | Kev piav qhia |
| Tam sim no Convergence | Muab cov me me tam sim no (10 A - 20 A) los ntawm ob peb txoj hlua mus rau hauv ib txoj kev loj dua tam sim no, txo tus naj npawb ntawm DC cables, kab poob, thiab cov nqi teeb tsa. |
| Kev tiv thaiv Circuit Court | Txhua txoj hlua input yog nruab nrog DC fuse (piv txwv li, NH00 hom) lossis qhov hluav taws xob me me (MCB) nrog lub peev xwm tawg ntawm 20 kA. Lub sab tso zis nta ib tug DC Circuit Court breaker rau overload thiab luv luv - tiv thaiv Circuit Court. |
| Kev tiv thaiv xob laim | T1 / T2 chav kawm Surge Protective Devices (SPDs) nrog Hauv Ntau dua lossis sib npaug ntawm 15 kA yog txuas nrog sib npaug ntawm qhov zoo / tsis zoo busbars thiab hauv av. Nyob rau hauv cov kev tshwm sim ntawm xob laim ntaus los yog switching overvoltages, lawv ua nyob rau hauv milliseconds mus hloov surge tam sim no rau hauv av, tiv thaiv PV modules thiab inverter. |
| Saib xyuas & Kev sib txuas lus | Hall sensors lossis shunts yog siv los sau cov ntaub ntawv rau txhua txoj hlua (tam sim no, busbar voltage, kub, SPD xwm txheej, rwb thaiv tsev, thiab lwm yam). Cov ntaub ntawv raug xa mus rau lub backend ntawm RS485/PLC/Wi-Fi rau tej thaj chaw deb qhov chaw txhaum. |
| Rov qab Kev Tiv Thaiv tam sim no & Kev rho tawm | Qee cov qauv muaj xws li anti-reverse diodes nyob rau hauv series ntawm cov tswv yim los tiv thaiv circulating currents ntawm cov hlua. Ib qho kev sib cais riam hloov tuaj yeem muab ntxiv rau ntawm qhov tso zis rau kev saib xyuas yooj yim. |
| Kev faib tawm & Kev xa tawm |
Muab lub zog hluav taws xob sib txuas rau lub inverter lossis DC faib txee. |
| Kev Tiv Thaiv Kev Nyab Xeeb | Muab ntau dhau, luv-circuit, xob laim, thiab rov qab kev tiv thaiv kev tiv thaiv kom ua haujlwm ruaj ntseg. |
| Kev soj ntsuam ntse | Tiag - lub sij hawm saib xyuas ntawm ntau yam tsis muaj (tam sim no, voltage, kub ib txoj hlua, thiab lwm yam) txhawb kev khiav hauj lwm thiab kev txij nkawm. |
