Khoom Description
Pebsurge arrester saib xyuas qhov systemntsuas tus ntes tam sim no ua ke nrog tsheb npav -voltage magnitude, zaus, thiab harmonic cov ntsiab lus. Qhov ntsuas kub thiab av noo hauv cheeb tsam muab cov ntsiab lus ntawm kev ua haujlwm rau kev xau- tam sim no.
Txoj Cai
Lub kaw lus ntsuas qhov xau tam sim no thiab qhov system voltage synchronously. Harmonic thiab theem laij lej cais cov tiv thaiv tiv thaiv los ntawm tag nrho cov xau tam sim no, thaum lub qhov tso tawm pov tseg cov xwm txheej xob laim thiab lub sij hawm thwj rau rwb thaiv tsev - xwm txheej trending.
Khoom nta
Lub surge arrester monitoring system muab cov neeg ntes cov xau tam sim no nrog lub tsheb npav synchronized -voltage reference. Harmonic thiab kev tawm tsam- suav cov ntaub ntawv muab cov ntsiab lus ntau dua li tag nrho tam sim no ib leeg. Yim caum lub zos modules txhawb ntau-bay ntes kev pab them nqi. Selectable sampling intervals sib npaug sib npaug nthuav dav thiab kev sib txuas lus load.
Cov xwm txheej ua haujlwm
Cov khoom yuav tsum tau nruab thiab ua haujlwm nyob rau hauv cov kev ntsuam xyuas tau teev nyob rau hauv cov kev tsis. Cov ntsiab lus tseem ceeb ntawm qhov chaw muaj xws li: zaus, thiab cov ntsiab lus sib haum xeeb. Local kub thiab humi. Khaws thaj chaw teeb tsa kom huv si, muaj cua txaus, tsis muaj roj corrosive thiab kev vibration hnyav, thiab muab cov lus qhia hauv av, tshem tawm, thiab lub zog zoo.

FAQ
Q: Cov ntaub ntawv dab tsi xav tau rau kev xaiv qauv?
A: Muab cov neeg ntes kom muaj nuj nqis, qib voltage, grounding- lead sizes, bus-voltage source, thiab sampling interval.
Q: Dab tsi yuav tsum tau kuaj ua ntej kev teeb tsa?
A: Txheeb xyuas tam sim no- qauv kev taw qhia, hauv av txuas ntxiv, qhov hluav taws xob- siv txuas, thaiv, thiab ib puag ncig- qhov chaw sensor.
Q: Yuav ua li cas cov cuab yeej lossis lub kaw lus tuaj yeem ua ke?
A: CAN thiab RS485 txuas txuas hauv zos modules thiab kev saib xyuas IED nyob rau hauv lub teeb tsa architecture.
Q: Cov kev xaiv twg yuav tsum tau lees paub ua ntej ntau lawm?
A: Paub meej tias module kom muaj nuj nqis, sensor apertures, voltage channels, txee, raws tu qauv gateway, thiab tswb thresholds.
