GDCO-301 Online Monitoring System ntawm Circulating Tam sim no ntawm Cable Sheath
Cov kab hluav taws xob siab tshaj 35kV feem ntau yog ib leeg-core cables nrog hlau sheath.Txij li cov hlau sheath ntawm ib leeg-core cable yog hinged nrog cov magnetic teb kab tsim los ntawm AC tam sim no nyob rau hauv cov tub ntxhais hlau, ob kawg ntawm ib tug tub ntxhais cable muaj ib tug high induced voltage.Yog li ntawd, kev ntsuas av tsim nyog yuav tsum tau coj los ua kom muaj qhov cuam tshuam ntawm qhov hluav taws xob muaj kev nyab xeeb (feem ntau tsis tshaj 50V, tab sis tsis pub ntau tshaj 100V nrog kev ntsuas kev nyab xeeb).Feem ntau, cov hlau sheath ntawm luv kab ib leeg-core cable yog grounded ncaj qha ntawm ib kawg thiab grounded los ntawm qhov sib txawv los yog tiv thaiv resistor ntawm lwm kawg.Cov hlau sheath ntawm kab ntev ib leeg - tub ntxhais cable yog grounded los ntawm peb - theem segmental cross - kev twb kev txuas.Tsis muaj teeb meem ntawm txoj kev hauv av twg yog txais yuav, zoo rwb thaiv tsev yog tsim nyog.Thaum lub rwb thaiv tsev ntawm lub cable puas lawm, cov hlau sheath yuav tsum grounded nyob rau hauv ntau lub ntsiab lus, uas yuav ua rau lub circulating tam sim no, ua rau kom poob ntawm sheath, cuam tshuam rau lub peev xwm nqa tam sim no ntawm lub cable, thiab txawm ua rau lub cable raug hlawv. vim overheat.Nyob rau tib lub sij hawm, lav lub high voltage cable hlau sheath grounding ncaj qha mus txuas qhov chaw kuj tseem ceeb heev, yog hais tias lub hauv paus ntsiab lus tsis tau zoo nyob rau hauv ntau yam yog vim li cas, lub cable hlau sheath tej zaum yuav nce sharply mus rau ob peb kilovolts txawm kaum tawm txhiab volts. , nws yog ib qho yooj yim uas yuav ua rau cov txheej sheath tawg thiab tas mus li tso tawm, ua rau qhov kub thiab txias ntawm cable txheej sheath los yog txawm hlawv.
GDCO-301 siv txoj kev circulating tam sim no.Thaum ib leeg-core cable hlau sheath yog nyob rau hauv ib txwm tej yam kev mob (ie, ib-point grounding), circulating tam sim no ntawm lub sheath, feem ntau capacitive tam sim no, yog heev me me.Thaum muaj ntau lub ntsiab lus earthing tshwm sim ntawm cov hlau sheath thiab tsim ib lub voj, circulating tam sim no yuav nce siab thiab tuaj yeem ncav cuag ntau dua 90% ntawm lub ntsiab tam sim no.Kev saib xyuas lub sijhawm tiag tiag ntawm cov hlau sheath ncig thiab nws cov kev hloov pauv tuaj yeem paub txog kev saib xyuas hauv online ntawm ntau lub ntiaj teb kev txhaum ntawm ib leeg-core cable hlau sheath, kom raws sij hawm thiab raug pom lub ntiaj teb txhaum, hauv paus tsis txhob tshwm sim ntawm cable sib tsoo thiab xyuas kom muaj kev nyab xeeb thiab txhim khu kev qha.
Nws siv GSM lossis RS485 ua hom kev sib txuas lus.Nws yog tsim rau multi-point hauv av txhaum xyuas ntawm ib tug tub ntxhais cables saum toj no 35kV.
GDCO-301 Online Monitoring System ntawm Circulating Tam sim no ntawm Cable Sheath suav nrog: chav tsev tseem ceeb ntawm kev saib xyuas cov cuab yeej thiab tam sim no transformer, kub thiab tiv thaiv tub sab sensor.Lub hom qhib tam sim no transformer yog ntsia rau hauv av kab ntawm cable sheath thiab yog hloov dua siab tshiab rau hauv ib tug thib ob teeb liab ua ntej lub soj ntsuam ntaus ntawv yog qhia.Lub ntsuas kub ntsuas yog siv los saib xyuas cov kab hluav taws xob kub, thiab cov khoom siv tiv thaiv tub sab yog siv los saib xyuas cov kab hauv av.Cov muaj pes tsawg leeg ntawm kev saib xyuas online ntawm cable sheath yog raws li hauv qab no:
