Digital Partial Discharge Comprehensive Analyzer
Khoom Taw Qhia
MEJFD-W1S Partial Discharge Tester yog ib qho tshiab digital ib nrab tso tawm ntsuas ntsuas tsim los ntawm peb lub tuam txhab. Nws tuav lub zog ntawm cov qauv yav dhau los thaum txo nws qhov loj me thiab ntxiv kev ua haujlwm zoo. Lub raj oscilloscope ib txwm siv thiab lub pob qhov rooj ua haujlwm tau hloov nrog 10.1-nti touchscreen, txhim kho kev ua haujlwm, yooj yim ntawm kev siv, thiab kev ntseeg tau.
Cov cuab yeej no siv 32-ntsis siab- kev ua haujlwm microcontroller Circuit Court ua ke nrog kev ua haujlwm touchscreen. Qhov no tsis yog tsuas yog ncua sijhawm ua haujlwm tab sis kuj muab cov yam ntxwv hauv qab no: ib qho - kov tsis siv neeg calibration; configurable siab -voltage test voltage division ratio; serial chaw nres nkoj kev sib txuas lus rau uploading cov ntaub ntawv xeem. Cov cuab yeej no muaj qhov ntsuas pom tau zoo, kev siv dav dav thoob plaws cov qauv kuaj, ntau qhov sib txawv hauv nws qhov kev nthuav dav, ntau zaus sib txuas ua ke (xya hom), thiab muaj zog tiv thaiv kev cuam tshuam. Thaum siv ua ke nrog lub tshuab hluav taws xob ntsuas pulse thiab cov khoom siv nkag, nws ua haujlwm raws li cov khoom siv hluav taws xob tso tawm los ntawm cov khoom siv hluav taws xob, cov chaw tsim khoom, thiab cov chaw tshawb fawb.

Cov tsis tseem ceeb xws li elliptical scan lub sij hawm puag, amplifier bandwidth, nce, thiab lub sij hawm lub qhov rais yog tag nrho adjustable ntawm ib tug - kov tswj ntawm lub touchscreen, kom ntseeg tau tias ua hauj lwm zoo.
II. Kev ntsuas kev ua tau zoo
1. High Detection Sensitivity: Rau cov qauv kuaj uas sib txawv sib npaug sib npaug, qhov tsis sib npaug ntawm qhov kev xav tau nce mus txog li 0.02 pC (suav nrog qhov ntsuas qhov ntsuas ntawm 0-25-100 pF). Qhov sib npaug Circuit Court rhiab heev adapts synchronously, ua kom meej meej ntes ntawm faint ib nrab tawm cov cim.
2. Kev ntsuas qhov dav: npog cov qauv kuaj nrog qhov sib npaug ntawm 6 pF mus rau 250 µF thiab kev ntsuas tawm ntawm 0.1 pC txog 10,000 nC, ua tau raws li qhov yuav tsum tau ua rau cov khoom siv hluav taws xob sib txawv thiab cov khoom siv.
3. Strong Anti-Interference Capability: Nruab nrog cuaj zaus sib txuas ua ke, lub amplifier's 3dB low-frequency end (10, 20, 40kHz) thiab high-frequency end (80, 200, 300kHz.) yog xaiv tau dawb Ua ke nrog lub sij hawm lub qhov rais muaj nuj nqi (qhov rais dav adjustable ntawm 5℃mus rau 170 degree, dual lub qhov rais tuaj yeem qhib nws tus kheej los yog ib txhij), nws zoo zam kev ruaj ntseg - theem cuam tshuam. Txhawb elliptical scan lub sij hawm puag ncig (hauv 30℃increments, mus txog 120℃rotation) ntxiv optimize cuam tshuam tsis kam.
4. Txhim khu kev ntsuas qhov tseeb: Pulse peak zaub yuam kev tsuas yog ± 3% (ntawm qhov ntsuas tag nrho), qhov ntsuas qhov ntsuas qhov ntsuas qhov yuam kev yog ± 1%, thiab qhov ntsuas qhov ntsuas qhov ua yuam kev yog tsawg dua ± 1%. Lub xoom calibration system tseem zoo ib yam nyob rau hauv tag nrho cov elliptical scan zaus, xyuas kom meej thiab txhim khu kev qha cov ntaub ntawv xeem.
III. Extensive Functional Adaptability
1. Muaj peev xwm luam theej duab thiab tso saib: Elliptical scan lub sij hawm puag txhawb ntau zaus (50/60, 100, 150, 200, 400Hz), nrog rau kev ua haujlwm hom npog elliptical, sinusoidal, thiab linear waveforms kom haum raws li cov kev xav tau sib txawv waveform soj ntsuam thoob plaws qhov kev sim; Lub touchscreen qhia meej txog qhov tseem ceeb xws li PD waveforms, PD qhov tseem ceeb, ntsuas qhov ntsuas hluav taws xob, thiab ntsuas zaus. Tshem tawm kom muaj nuj nqis nyeem tau hloov ntawm 1-digit lossis 2-digit decimal qhia raws li qhov loj rau kev nyeem tau zoo dua.
2. High Input Unit Adaptability: Nruab nrog input units featuring 12 tunable capacitance ranges thiab ib resistive input unit, haum rau tam sim no rms qhov tseem ceeb ntawm 30mA mus rau 50A (unbalanced circuits) thiab 0.25A rau 300A (balanced circuits). Qhov kev hloov pauv no ua rau muaj kev sim ntawm cov qauv uas muaj qhov sib txawv thiab qhov ntsuas tam sim no.
3. Ntau yam Daim Ntawv Thov Scenarios: Thaum siv nrog calibration pulse generators thiab input units, nws yog dav siv nyob rau hauv lub hwj chim utilities, manufacturing nroj tsuag, thiab cov chaw tshawb fawb.
