VLF AC Hipot Test Set

CovVLF Tan Delta test system, kuj dav lub npe hu ua0.1Hz VLF dielectric poob ntsuas ntaus ntawv, yog ib qho tshwj xeeb rwb thaiv tsev raws li cov khoom siv tshuaj ntsuam xyuas ntau. Nws yog tsim tshwj xeeb rau kev kuaj capacitive siab -voltage fais fab cuab tam, suav nrogXLPE fais fab cables, generator stators,Capacitive voltage transformers (CVT), thiab siab -voltage capacitor.

Qhov kev sim no muab cov ntaub ntawv kuaj xyuas txhim khu kev qha rau cov neeg siv hluav taws xob thoob ntiaj teb thiab cov neeg ua haujlwm cog lus los ntawm kev txheeb xyuas qhov tsis zoo ntawm dielectric los tshawb pom qhov teeb meem ntawm kev rwb thaiv tsev.

Overcoming Equipment Size & Weight Constraints

Kab lig kev cai- zaus hipot testers raug txwv nruj heev los ntawm cov qauv ntsuas. Kev sim ntev -qhov deb siab-voltage cables yuav tsum muaj cov khoom siv loj, hnyav uas nyuaj rau kev thauj mus los thiab xaim.

Cov0.1Hz VLF tan delta test systemdaws qhov teeb meem no. Nws tsuas xav tau1/50th ntawm lub zog muaj peev xwmpiv rau lub zog- kev ntsuas zaus. Qhov no tso cai rau cov kws tshaj lij ua cov kev sim teb rau siab - cov peev txheej muaj peev xwm thaum txo cov khoom hnyav thiab ntawm - qhov chaw ua haujlwm siab.

Siab rhiab heev rau nkaum rwb thaiv tsev tsis xws luag

Ntawm 0.1Hz, sab hauv conduction thiab interfacial polarization poob yog amplified, uaVLF dielectric poob ntsuasrhiab heev rau latent faults nyob rau hauvXLPE rwb thaiv tsevxws li cov ntoo dej, dej noo, thiab kev sib koom ua ke delamination.

Kev ntsuas qhov tsis zoo & Kev ntsuas lub neej

Siv stepped voltage los tsimU-tanδ nkhaus, nws xam ∆tanδ rau qib rwb thaiv tsev ibIEEE 400.2 tus qauv. Nws txawv qhov kev laus tsis sib xws los ntawm cov xwm txheej hauv cheeb tsam, zam kev kuaj tsis tau thiab pab ntsuam xyuas lub neej txuas ntxiv ua ntej kev tawg tshwm sim.

 

Peb tus kheej- tau tsimVLF tan delta integrated test systemua ke ib qho ultra-tsawg zaus siab-voltage generator nrog high-precision dielectric poob ntsuas unit. Engineers tuaj yeem ua ob qho tib siVLF tiv thaiv kev simthiabntsuas ntsuasnrog ib qho kev sib txuas ntawm ib leeg, txo qhov kev pheej hmoo ntawm kev nyab xeeb thiab ua kom nrawm ntawm - lub sijhawm ntsuas qhov chaw.

Advanced Anti-Interference Algorithm

Muab ruaj khov, txhim khu kev qha ntsuas precision txawm nyob rau hauv hnyav electromagnetic teb ib puag ncig, xws li substations thiab cable trenches. Qhov no kiag li tshem tawm cov ntaub ntawv drift thiab nyeem tsis tseeb.

02

Ib -Click Comprehensive Testing Reports

Txhawb ntau-stepped voltage automated data logging. Nws tsim teb-cov ntaub ntawv npaj ua tiav nrogtanδ tus nqi, U-tanδ nkhaus, thiab ∆tanδ cov txiaj ntsiguas ua raws li thoob ntiaj teb kev siv hluav taws xob hluav taws xob archiving thiab cov qauv kev lees paub.

03

Factory-Reliability & Precision

Txhua chav nyob ua haujlwm nruj ntau- puag ncig siab -voltage calibration thiab aging tests. Ob qhov siab -voltage output stability thiab theem ntsuas qhov tseeb yog nruj me ntsis ntsuas tiv thaivIEEE 400.2 tus qauv.
