Dab tsi yog "anti-reverse current meters" thiab "anti-backflow meters"? Muaj coob tus neeg tsis meej pem ob, txawm tsis ntseeg tias lawv yog tib lub cuab yeej. Qhov tseeb, lawv cov ntsiab lus, kev ua haujlwm, thiab kev siv cov xwm txheej yog qhov sib txawv. Hnub no, peb yuav pab koj kom meej meej txog qhov sib txawv.
Ua ntej, cia peb qhia meej: Dab tsi yog "anti-reverse metering"?
Ua ntej, peb yuav tsum tau kho ib qho kev xav tsis zoo: "Anti-reverse metering" tsis yog lub ntsiab lus ntawm kev lag luam, tab sis yog cov lus luv luv rau "ib meter nrog anti-reverse metering function." Nws cov ntsiab lus tseem ceeb yog "metering tswj."
Hauv cov ntsiab lus yooj yim, "anti-reverse meter" yog zoo li "ib- txoj kev bookkeeper," piv txwv li, nws tsuas paub txog "hluav taws xob xa los ntawm kab hluav taws xob" thiab tsis yog "hluav taws xob xa tawm los ntawm tus neeg siv," thiab nws tsis muaj peev xwm los tswj cov kev taw qhia ntawm cov dej ntws tam sim no.
Niaj hnub no, cov ntsuas hluav taws xob hluav taws xob feem ntau siv ntau qhov tsim nyog thiab qib siab rau pem hauv ntej thiab thim rov qab ntsuas hauv peb txoj kev ntsuas ntsuas tau pom hauv cov duab saum toj no, thiab tsis tshua siv rov qab xyuas lossis qhov ntsuas qhov tseeb.
Kev piav qhia ntxiv: Cov Ntsiab Lus Qhia thiab Kev Ua Haujlwm ntawm Anti-Backflow Meters
Tsis zoo li lub ntsiab lus thiab cov lus hais "anti-backflow meter," anti-backflow meter yog kev lag luam- cov lus tus qauv, sawv cev rau lub ntsuas ntsuas ntse tshwj xeeb tsim los ua kom muaj kev nyab xeeb ntawm lub zog hluav taws xob hauv lub zog tshiab.
- Hauv kev faib hluav taws xob photovoltaic (PV) thiab lub zog cia khoom, thaum lub zog tsim hluav taws xob ntau tshaj qhov xav tau hauv zos, cov hluav taws xob ntau dhau rov qab mus rau hauv daim phiaj pej xeem (piv txwv li, "rov qab ntws"). Qhov no tuaj yeem ua rau muaj qhov hluav taws xob hauv zej zog nce ntxiv, kev sib haum xeeb tsis sib haum, thiab txawm tias muaj kev puas tsuaj rau cov khoom siv faib khoom, ua rau muaj kev tiv thaiv relay tsis ua haujlwm, thiab ua txhaum daim phiaj kev sib cog lus.
- Lub luag haujlwm tseem ceeb ntawm kev tiv thaiv -reverse flow meter yog saib xyuas cov kev taw qhia tam sim no hauv lub sijhawm. Thaum rov qab ntws tawm, nws yuav siv sij hawm tswj kev ntsuas tam sim: yog xa lub teeb liab mus rau lub inverter kom dynamically txo lub zog tsim kom txog thaum rov qab ntws ploj, los yog ncaj qha disconnecting daim phiaj sib txuas Circuit Court kom tsis txhob rov qab thiab xyuas kom ruaj ntseg kab sib chaws ntawm nws qhov chaw.
Tsis tas li ntawd, anti-reverse flow meters muaj peb lub luag haujlwm ntxiv:
1. Bidirectional Metering
Nws tuaj yeem sau tau ob qho tib si hluav taws xob yuav los ntawm kab hluav taws xob (kev siv hluav taws xob txuas ntxiv, siv rau kev them nqi hluav taws xob) thiab cov hluav taws xob tsim los ntawm cov khoom siv hluav taws xob txuas ntxiv (rov qab tiam, siv los xam cov nyiaj tau los ntawm cov khoom siv hluav taws xob).
2. Kev ceeb toom tsis zoo
Nws saib xyuas qhov tsis xws li qhov hluav taws xob, qhov tam sim no, thiab lub zog ntawm lub sijhawm, thiab ceeb toom cov neeg ua haujlwm saib xyuas ntawm lub tswb nrov hauv zos lossis tej thaj chaw deb laub ceeb toom thaum muaj kev tsis sib haum xeeb.
3. Cov ntaub ntawv xa tawm
Cov ntaub ntawv siv hluav taws xob tau xa mus rau lub zog tswj hwm lub platform ntawm RS-485 kev sib txuas lus, WiFi, thiab lwm txoj hauv kev, ua kom yooj yim rau cov neeg siv kev txheeb xyuas ntawm kev siv hluav taws xob thiab cov tiam tshiab.
Kev sib piv tseem ceeb: Ib lub rooj kom nkag siab qhov sib txawv
Txhawm rau ua kom qhov sib txawv ntau qhov kev xav, peb tau muab piv rau ob los ntawm qhov loj me, qhia meej txog lawv qhov sib txawv:
Common Misconceptions: Tsis txhob nkim cov xwm txheej no
- Misconception 1:
"Anti-reverse meter yog tib yam li kev tiv thaiv kev ntsuas rov qab"-Tsis yog! Lub qub yog ib lo lus hais txog "metering thiab tswj cov cuab yeej," thaum lub tom kawg yog tus qauv "kev tswj hwm kev nyab xeeb." Lawv lub luag haujlwm thiab lub luag haujlwm sib txawv kiag li thiab tsis tuaj yeem sib npaug.
- Misconception 2:
"Ob leeg tuaj yeem daws qhov teeb meem yog tias muaj qhov rov qab tam sim no"-Ua txhaum! Anti-reverse meters tsuas yog "tsis ntsuas" rov qab tam sim no; lawv tsis tuaj yeem tiv thaiv tam sim no los ntawm kev ntws rov qab thiab tsis tuaj yeem daws qhov teeb meem kev nyab xeeb ntawm kab hluav taws xob los ntawm qhov rov qab tam sim no. Backflow tiv thaiv meters, ntawm qhov tod tes, nquag tiv thaiv rov qab tam sim no, zam kev nyab xeeb ntawm lawv qhov chaw.
- Misconception 3:
"Nruab lub anti-reverse meter yog txaus rau lub hnub ci zog hauv tsev"-Tsis yog! Yog tias muaj hluav taws xob ntau dhau los ntawm lub hnub ci hluav taws xob hauv tsev, rov qab tuaj yeem cuam tshuam kev nyab xeeb ntawm daim phiaj. Daim phiaj kev sib txuas lus pom zoo nyob rau hauv feem ntau thaj tsam txwv tsis pub muaj kev cuam tshuam rov qab thiab xav tau kev teeb tsa ntawm kev tiv thaiv kev ntsuas rov qab, tsis yog yooj yim los tiv thaiv -reverse meters. Txwv tsis pub, koj tuaj yeem ntsib cov lus ceeb toom thiab kev nplua rau kev sib txuas ntawm kab hluav taws xob los ntawm lub tuam txhab fais fab.
Cov ntsiab lus
Xaiv raws li koj xav tau, precisely phim koj scenario
Yooj yim muab tso, qhov sib txawv ntawm qhov sib txawv ntawm ob tuaj yeem ua tiav raws li: tiv thaiv kev ntsuas rov qab tam sim no, thiab tiv thaiv kev ntsuas rov qab tam sim no kom muaj kev nyab xeeb.
