Cable Distributed Partial Discharge Testing System

Khoom Taw Qhia

Kev kuaj xyuas qhov paug ib nrab tau ntev yog thawj qhov tsis yog{0}}tshuaj xyuas hluav taws xob puas tsuaj rau cov kab hluav taws xob hluav taws xob (tshwj xeeb tshaj yog cov cables yas), tau suav tias yog cov txheej txheem ntsuas hluav taws xob zoo tshaj plaws rau kev soj ntsuam thiab kawm txog cov teeb meem kev laus ntawm rwb thaiv tsev los ntawm kev tso tawm ib nrab.

Thaum ib nrab paug tshwm sim nyob rau hauv ib tug cable, lub resulting paug kab noj hniav tsim ib tug tiag tiag impedance. Cov pulses generated feem ntau yog unipolar, nthuav tawm lub sijhawm luv luv thiab nqaim mem tes dav. Raws li cov pulses propagate los ntawm lub cable, lawv qhia attenuation thiab scattering yam ntxwv, tuaj txog ntawm qhov ntsuas taw tes nrog nce mem tes dav thiab txo amplitude.

Thaum kawg - ntawm - lub neej theem ntawm cables (tom qab 25 xyoo ntawm kev ua haujlwm), qhov tsis ua haujlwm ntawm cov hluav taws xob cables nce ntau vim qhov cuam tshuam ntawm dendritic aging ntawm cable rwb thaiv tsev nws tus kheej, electrothermal aging, thiab aging ntawm accessories. Kev ua haujlwm thiab kev tshawb fawb tshawb pom ob qho tib si hauv tebchaws thiab thoob ntiaj teb qhia tau hais tias qhov kev puas tsuaj thaum ntxov ntawm XLPE fais fab cable kev ua haujlwm lossis nws lub neej kev pabcuam feem ntau nyob ntawm kev laus dendritic ntawm nws qhov nruab nrab insulating. Kev ntsuas qhov tso tawm ib nrab yog ib txoj hauv kev zoo rau kev ntsuas ntau npaum li cas ntawm qhov dendritic deterioration. Piv txwv li: Thaum pib ntawm kev tsim cov dendrite, cov kab hluav taws xob ib nrab ntawm qhov tso tawm yog kwv yees li 0.1 pC. Thaum dendrites nce mus rau lub xeev tseem ceeb ntawm kev puas tsuaj ntawm dielectric, qhov kev tso tawm ib nrab tuaj yeem ncav cuag 1000 pC.

Lub kaw lus no ua kom muaj tseeb- lub sijhawm saib xyuas cov kab hluav taws xob ib nrab ntawm ib ntus - los ntawm - ntu lossis kho - taw tes los ntawm siab - rhiab heev PD sensors ntsia rau siab -voltage cable grounding leads, ua ke nrog cov txheej txheem digital thiab cov khoom xa tawm. Cov ntaub ntawv raug xa los ntawm fiber ntau -optic networks lossis mobile 4G tes hauj lwm mus rau tus saib xyuas server. Server-sab software qhia PD cov ntaub ntawv thiab spectra sau los ntawm txhua chav kuaj xyuas. Los ntawm kev teeb tsa kev tshawb nrhiav qhov pib, thiab ib puag ncig tsis muaj. Thaum kuaj pom ib feem ntawm cov ntaub ntawv tso tawm ntau tshaj qhov pib, lub kaw lus cia li teeb tsa cov lus ceeb toom qhia tias muaj peev xwm thaiv kev puas tsuaj ntawm cov kab hluav taws xob. Cov kev ntsuas cuam tshuam tuaj yeem raug coj los ua, xws li xa cov neeg ua haujlwm los ua - qhov kev kuaj pom qhov tsis raug ntawm qhov chaw. Thaum pom tau tias qhov txhaum, yuav tsum tau ua kom sai li sai tau kom tsis txhob muaj kev phom sij ntxiv.
