Vim li cas Kev Ntsuas Ib Nrab Zoo li xav tau ntau yam khoom siv

Qhib cov khoom siv PD thiab cov kab khoom sib txuas nrawm: TEV sojntsuam ntawm no, HFCT clamp nyob ntawd, tej zaum UHF kav hlau txais xov thiab tus nqi sib cais - ntsuas ntsuas nrog nws tus kheej ntsuas ntsuas. Cov neeg ua haujlwm hauv cheeb tsam tsis xav txog nws - ib feem ntawm qhov kev tso tawm pov tseg tiag tiag rub cov khoom siv ntau dua li cov xwm txheej feem ntau- saib xyuas cov haujlwm.

Lub hauv paus ua rau yog physics, tsis yog tus neeg muag khoom upselling. Ib qho kev tshwm sim tawm ib zaug radiates lub mem tes tam sim no, xov tooj cua- zaus tawg, thiab lub suab nrov ping. Tsis muaj ib tus sensor ntes tag nrho peb qhov zoo. TEV (hloov lub ntiaj teb voltage) khaws cov ntaub ntawv hloov pauv ntawm cov hlau-clad switchgear. UHF probes ua hauj lwm nyob rau hauv 300 MHz-3 GHz band qhov twg GIS thiab transformer tank tsis xws luag tshwm sim kom meej. HFCT clamps nyeem mem tes tam sim no ntawm cable hauv av thiab txoj hauv nruab nrab. Ultrasonic taub hau ntes nto taug qab thiab corona koj yuav nco nrog hluav taws xob coupling ib leeg. Cia siab rau TEV nkaus xwb thiab cov voids sab hauv hauv lub cable sib koom ua ke nyob tsis pom; cia siab rau HFCT nkaus xwb thiab corona ntawm ib tug ntse busbar ntug taug kev dhau koj.

Cov cuab yeej cuab tam ntxiv lwm tus lej. Cable terminations, roj- puv transformers, AIS panels, thiab roj-insulated switchgear (GIS) txhua propagate PD txawv - yog li cov coupling txoj kev hloov txawm thaum lub defect yog tib yam.

Tom qab ntawd muaj kev sib cais hauv online vs offline. Kev tshawb fawb hauv online siv qhov kev pabcuam hluav taws xob nrog TEV, UHF, lossis HFCT thiab tsis muaj hluav taws xob. Offline txais kev ua hauj lwm raws li IEC 60270 xav tau ib tug coupling capacitor, calibrated mem tes txhaj (feem ntau 1 pC mus rau 500 pC kauj ruam), thiab ib tug ntsuas impedance nyob rau hauv 100 kHz-1 MHz band rau pom meej nqi nyob rau hauv picocoulombs. Qhov ntawd yog qhov sib txawv toolchain nkaus.

Cov txheej txheem fragmentation tsis pab. IEC 60270, IEEE 400.3, IEC TS 62478, thiab cov cuab yeej cuab tam- cov lus qhia tshwj xeeb rau txhua qhov taw qhia rau cov chav ntsuas ntsuas sib txawv me ntsis. Tsib txoj kev tshawb pom × plaub tsev neeg khoom vaj khoom tsev × ob hom kev sim - cov ntawv teev npe zoo li tsis muaj qhov kawg.

Txoj kev kho kom raug yog - qhov loj me, tsis yog yuav txhua yam. Rau kev taug kev energized-downs ntawm switchgear thiab transformers, Huazheng's HZ-9003C bundles composite TEV, UHF, HFCT, thiab ultrasonic sensors nyob rau hauv ib lub portable host nrog adaptive suab filtering - multi-sensor fusion mus kom ze cov khoom siv tam sim no cia siab rau kev sib cais plaub lub thawv hauv online.

Thaum lub Scope hu kom muaj nuj nqis pC nyeem ntawm transformers, cables, los yog GIS thaum lub sij hawm FAT los yog hluav taws xob ua hauj lwm, HZJF-9102 dual-channel unit npog 0.1 pC–100,000 pC, 80 kHz–300 kHz bands, 0, 0.ibs. Pulse generator ua raws li IEC 60270. Rau cov chaw sim juggling wide test-object capacitance (6 pF rau 250 µF), HZ-9025B ntxiv cuaj zaus xaiv-band ua ke kom tsis txhob muaj suab nrov ntawm lub qhov rais ntsuas.

Ib txoj cai peb dhau mus rau cov kws tshaj lij tshiab: phim cov sensors rau qhov tsis xws luag uas koj xav tias, tsis yog rau daim ntawv qhia kev yees duab. Lub nkoj cable xav tau HFCT thiab offline ntsuas ntsuas; pab pawg GIS substation nyob ntawm UHF. Consolidated handhelds txiav qhov hnyav thauj, tab sis lawv tsis tshem tawm qhov kev xav tau ntawm ntau lub cev sib txuas - lawv tsuas yog muab tso rau hauv ib rooj plaub.

Xav tau ib qho khoom siv scoped rau koj cov khoom vaj khoom tsev? Huazheng Hluav taws xob tsim CE- ntawv pov thawj ib nrab tso tawm cov ntsuas los ntawm cov ntsuas ntsuas ntawm tes mus rau ntau -channel lab systems - tsim nyog kos npe rau koj IEC 60270 vs kev tshuaj ntsuam online sib cais ua ntej koj xaj.
