Dab tsi yog cov tswv yim tswv yim rau kev tswj PV inverters?
Lub photovoltaic inverter yog ib feem tseem ceeb ntawm tag nrho photovoltaic zog tsim system. Thaum nws txuas nrog daim phiaj rau kev tsim hluav taws xob, nws txuas ncaj qha mus rau daim phiaj hluav taws xob, thiab nws qhov tseem ceeb yog qhov tseeb ntawm nws tus kheej. Yog li ntawd, txhim kho tus cwj pwm ntawm kev siv thiab tswj cov photovoltaic inverters kom raug, thiab ua tib zoo ua 13 cov ntsiab lus hauv qab no kom ntseeg tau tias tus nqi online ntawm photovoltaic inverters yog> 98 feem pua, thiab txuas ntxiv kom ntseeg tau cov nyiaj tau los ntawm lub zog hluav taws xob.
1. Ua ntej siv PV maub los thiab inverter, koj yuav tsum nyeem phau ntawv qhia.
2. Ua tib zoo saib cov cim ceeb toom ntawm lub tshuab.
3. Ua ntej pib, xyuas seb qhov input voltage puas zoo li qub.
4. Thaum lub sijhawm ua haujlwm, ua tib zoo saib seb qhov kev txiav txim ntawm kev hloov mus rau thiab tawm puas yog, thiab seb qhov ntsuas ntawm txhua lub taub hau thiab qhov taw qhia lub teeb yog qhov qub.
5. Thaum lub sijhawm ua haujlwm, xyuam xim rau qhov chaw ntawm overcharge voltage thiab overdischarge voltage ntawm tus maub los, uas yuav tsum tau ua raws li cov qauv tsim.
6. Nyob rau hauv cov kev tshwm sim ntawm qhib Circuit Court, overcurrent, overvoltage, overheating thiab lwm yam faults, photovoltaic maub los thiab inverter feem ntau yuav cia li kaw thiab nkag mus rau hauv lub xeev tiv thaiv. Lub sijhawm no, tsis txhob tig nws tam sim ntawd! Qhov laj thawj yuav tsum raug txheeb xyuas thiab kho ua ntej pib pib.
7. Muaj hluav taws xob siab nyob rau hauv inverter txee. Hnub ua hauj lwm, thov kaw lub qhov rooj.
8. Thaum lub ambient kub yog ntau tshaj 30 degree, peb yuav tsum tau ua lub thermal tswj kom zoo los tiv thaiv overheating ntawm cov khoom thiab prolong nws cov kev pab cuam lub neej.
9. Tshawb xyuas seb qhov kub, suab thiab tsis hnov tsw hauv lub tshuab puas txawv txav.
10. Xyuas seb cov kiv cua txias ntawm modules, reactors thiab transformers hauv inverter tuaj yeem pib thiab nres raws li qhov kub thiab txias. Thaum lub kiv cua khiav, txawm tias muaj kev vibration loj lossis lub suab nrov txawv txav, yog tias nws txawv txav, thawj lub hwj chim tawm, thiab tom qab ntawd kho nws.
11. Txheeb xyuas qhov zoo-rau-hauv av, qhov tsis zoo-rau-hauv av, thiab rwb thaiv tsev tsis zoo ntawm cov ncej zoo thiab tsis zoo ntawm DC lub npav. Tus nqi kuj yuav tsum siab dua 2MΩ.
12. Txheeb xyuas cov hlua hluav taws xob thiab cov terminals ntawm ntau qhov chaw kom xoob thiab xeb (xws li fuses, kiv cua, fais fab modules, input thiab output terminals, grounding, etc.), thiab kho tam sim ntawd yog tias pom muaj qhov txawv txav.
13. Ib ntus txiav lub Circuit Court breaker ntawm qhov tso zis sab (daim phiaj sab) ntawm AC daim phiaj ib zaug, thiab xyuas seb lub inverter puas tuaj yeem tso tseg lub zog ntawm daim phiaj tam sim ntawd.
