Nyeem Qhov Sib Txawv Ntawm DTU, FTU, TTU, thiab RTU Hauv Ib Tshooj (3)
Distribution Transformer Supervisory Terminal Unit (TTU)
TTU saib xyuas thiab sau cov kev khiav hauj lwm ntawm kev faib transformers, thiab xam qhov voltage RMS, tam sim no RMS, active zog, reactive zog, hwj chim yam, thiab active zog txhua txhua 1 mus rau 2 feeb raws li peb-theem voltage thiab tam sim no sampling qhov tseem ceeb ntawm qhov tsawg. -voltage sab, reactive zog, thiab lwm yam kev khiav hauj lwm tsis. TTU cov ntaub ntawv thiab txuag lub sijhawm (ib lub lis piam lossis ib hlis) thiab tus nqi teev teev ntawm cov lus hais saum toj no hauv ib hnub, qhov siab tshaj plaws thiab qhov tsawg kawg nkaus ntawm qhov hluav taws xob thiab tam sim no thiab lawv lub sijhawm tshwm sim, lub sijhawm siv hluav taws xob cuam tshuam, thiab lub sijhawm rov qab los. TTU cov ntaub ntawv kaw tseg yog khaws cia rau hauv lub cim xeeb tsis hloov pauv ntawm lub cuab yeej, thiab cov ntsiab lus kaw yuav tsis ploj thaum lub cuab yeej raug kaw. Lub chaw nres tsheb tseem ceeb ntawm kev faib tawm tsis tu ncua nyeem TTU qhov ntsuas tus nqi thiab cov ntaub ntawv keeb kwm los ntawm kev sib txuas lus, thiab pom cov teeb meem ua haujlwm raws sij hawm xws li transformer overload thiab fais fab tuag. Raws li cov ntaub ntawv kaw tseg, kev txheeb xyuas qhov ntsuas hluav taws xob tsim nyog tus nqi, kev ntseeg tau ntawm lub zog hluav taws xob, thiab cov yam ntxwv ntawm kev thauj khoom, thiab muab cov ntaub ntawv yooj yim rau kev kwv yees kev thauj khoom, kev npaj sib faib network, thiab kev soj ntsuam kev sib tsoo. Yog tias tsis muaj kev sib txuas lus tsis muaj, siv lub khoos phis tawj tuav los nyeem cov ntaub ntawv ntawm qhov chaw txhua lub lim tiam lossis hli, thiab tom qab ntawd hloov mus rau qhov chaw xa khoom network tswv lossis lwm qhov kev tshuaj xyuas. Cov qauv ntawm TTU zoo ib yam li FTU vim tias nws tsuas muaj cov ntaub ntawv tau txais, kaw, thiab kev sib txuas lus ua haujlwm, tab sis tsis muaj kev tswj hwm, cov qauv yooj yim dua. Txhawm rau kom yooj yim rau kev tsim thiab txo tus nqi, TTU yog siv los ntawm kev hloov pauv hluav taws xob ncaj qha thiab kho kom haum rau sab qis-voltage ntawm cov khoom siv hluav taws xob thiab tsis tau nruab nrog lub roj teeb. Thaum muaj ib qho reactive fais fab nyiaj them nyiaj capacitor bank ntawm qhov chaw, thiaj li tsis txhob rov ua lag luam, TTU yuav tsum ua kom lub capacitor switching tswj muaj nuj nqi.
Feature ntawm TTU:
Nws yog tsim rau kev soj ntsuam thiab hluav taws xob ntsuas hluav taws xob ntawm cov tuam txhab muab hluav taws xob, cov tuam txhab hluav taws xob hauv nroog, cov chaw tsim hluav taws xob, cov chaw lag luam thiab cov mining, cov tsev kawm qib siab tub rog, cov chaw tswj xyuas hluav taws xob nyob deb nroog, thiab 100-500KVA faib transformers. Ua ke nrog kev saib xyuas kev siv hluav taws xob rau kev ntsuam xyuas cov kab poob, nws tseem tuaj yeem xa tag nrho cov ntaub ntawv mus rau qhov chaw tswj xyuas hluav taws xob siv hluav taws xob los ntawm GPRS kev sib txuas lus, muab qhov kev txiav txim siab tiag tiag thiab qhov tseeb tshaj plaws rau kev ua kom zoo ntawm cov khoom siv hluav taws xob tsawg.
