Advanced cov txheej txheem rautxhaum simulation thiab ib nrab tso tawm tsom xamhauv gas-insulated switchgear
Taw qhia
Gas-insulated switchgear (GIS), ib qho tseem ceeb ntawm cov tshuab kis tau tus mob niaj hnub, sib txuas cov qauv tsim nrog kev ua tau zoo. Txawm li cas los xij, kev ncaj ncees ntawm GIS rwb thaiv tsev yog qhov tseem ceeb rau kev ua haujlwm kev nyab xeeb. Cov txheej txheem kuaj pom ib nrab (PD) kev kuaj pom, ua ke nrog kev sim ua yuam kev, tau tshwm sim los ua cov txheej txheem siab tshaj plaws rau kev ntsuam xyuas cov xwm txheej rwb thaiv tsev thiab tiv thaiv kev puas tsuaj loj. Qhov kev soj ntsuam kev tshawb fawb no tshawb nrhiav txoj hauv kev tshiab hauv kev ua haujlwm ntawm GIS txhaum simulation thiab tshuaj xyuas seb cov khoom siv hluav taws xob cuam tshuam li cas yog hloov kho cov tswv yim tswj xyuas qhov tseeb.
Kev nkag siabGIS Fault SimulationTechnology
Fault simulation apparatus yog ib qho cuab yeej tseem ceeb rau kev rov tsim cov teeb meem kev rwb thaiv tsev uas tau ntsib thaum lub sijhawm ua haujlwm GIS. Cov txheej txheem siab heev no tuaj yeem ua tiav ntau hom kev ua txhaum hauv ib puag ncig kev sim tswj:
Metallic Particle Contamination: Simulates dawb do txav los yog tsau hlau hais, uas nquag ua rau rwb thaiv tsev tawg
Floating Potential Faults:Replicates tej yam kev mob uas cov Cheebtsam poob kom zoo earthing, ua rau muaj teeb meem paug dej
Insulator nto contamination:Simulates scenarios qhov twg deg contamination txo dielectric zog
Khoom insulator void defects: Replicates zuj zus degradation uas tshwm sim los ntawm cov kab noj hniav nyob rau hauv cov khoom insulating khoom
Advanced thev naus laus zis rau kev kuaj pom qhov tso tawm ib nrab
Kev kuaj pom ib nrab nyob rau hauv cov ntawv thov GIS niaj hnub no suav nrog ntau cov thev naus laus zis uas ua haujlwm sib koom ua ke kom ua tiav cov peev txheej ntsuas:
Ultra- kuaj pom qhov siab (UHF)
Kev kuaj UHF tau dhau los ua tus qauv kev lag luam rau GIS daim ntawv thov thiab kuaj cov hluav taws xob tsis sib xws hauv qhov ntau zaus ntawm 300 MHz txog 3 GHz. Txoj kev no yog tus cwj pwm los ntawm qhov tshwj xeeb rhiab heev hauv kev tshawb pom cov paug tawm thaum ntxov thiab tuaj yeem sib txawv ntawm cov suab nrov sab nraud zoo.
Acoustic emission ntsuas
Acoustic sensors ntes cov nthwv dej siab uas tsim los ntawm kev ua haujlwm tawm ib nrab thiab muab cov ntaub ntawv tseem ceeb ntawm qhov chaw ntawm qhov tsis xws luag. Cov thev naus laus zis no tau ua pov thawj tshwj xeeb tshwj xeeb rau kev nrhiav qhov tsis xws luag hauv cov txheej txheem GIS nyuaj.
Transient Earth Voltage (TEV) Measurement
TEV kuaj xyuas xyuas cov dej ntws tawm los ntawm kev ntsuas siab - zaus voltages ntawm lub ntiaj teb nto. Qhov no tsis yog - txoj kev ntxeem tau tuaj yeem ua ke nrog lwm cov txheej txheem tshawb nrhiav kom paub meej.
Kev lag luam daim ntawv thov thiab kev xav txog kev siv
Kev siv cov thev naus laus zis tshiab no nthuav dav ntau yam, suav nrog cov khoom siv hluav taws xob xa hluav taws xob, cov chaw tsim khoom, thiab cov phiaj xwm kev tsim kho vaj tse. Thaum siv, yuav tsum tau ua tib zoo xav txog cov hauv qab no:
Kev ntsuas qhov system yuav tsum tau ua kom haum rau cov kev teeb tsa GIS tshwj xeeb thiab kev ua haujlwm kom ntseeg tau qhov tseeb. Ib puag ncig yam tseem ceeb (xws li kub hloov pauv thiab kev cuam tshuam electromagnetic) yuav tsum muaj cov tswv yim txo kom tsim nyog. Cov kws tshaj lij hauv kev txhais cov ntaub ntawv tseem ceeb heev rau kev paub qhov txawv tsis muaj teeb meem tshwm sim los ntawm cov teeb meem tawm hauv cov dej num tiag.
Tsis tu ncua validating system kev ua tau zoo siv calibrated defect simulators xyuas kom meej qhov tsis tu ncua thiab kev ntseeg siab ntawm kev soj ntsuam cov kev pab cuam.

Cov thev naus laus zis no muab cov neeg siv hluav taws xob ua haujlwm nrog cov cuab yeej muaj zog rau kev ntsuas kev tiv thaiv kev tiv thaiv, thaum kawg txhim kho kev ntseeg tau thiab kev nyab xeeb. Raws li kev tsim kho thev naus laus zis txuas ntxiv tshwm sim, muaj peev xwm txhawm rau tshawb pom qhov ua txhaum thaum ntxov thiab kuaj pom tseeb yuav txhim kho tsis tu ncua, yog li ua tau raws li cov kev xav tau hloov zuj zus ntawm cov khoom siv hluav taws xob niaj hnub no.
