Relay tiv thaiv testernyob rau hauv ultra-high voltage fais fab tuaj yeem pab ntau tus neeg ua haujlwm fais fab ua ntau yam kev ntsuas hluav taws xob yooj yim dua.
Yuav ua li cas los teeb tsa qhov sib txawv ntawm microcomputer relay tiv thaiv tester:
1. Kev xaiv sib txawv
Variable: Xaiv cov channel uas yuav tsum tau hloov los ntawm cov ntawv qhia zaub mov nco-down, raws li qhia hauv daim duab, nrog rau theem A voltage xaiv raws li qhov sib txawv.
Waveform: yog hais txog tus naj npawb ntawm superimposed harmonics, xws li DC mus rau 20th harmonics
Amplitude cov kauj ruam loj: Cov kauj ruam loj ntawm no kuj sib raug rau "txoj kev sawv cev ntawm kev sib haum xeeb". Thaum xaiv 'qhia hauv amplitude', cov kauj ruam loj kuj qhia nyob rau hauv amplitude, nrog units ntawm A lossis V; Thaum xaiv 'qhia raws li qhov feem pua ntawm lub hauv paus nthwv dej', cov kauj ruam loj kuj tau qhia raws li feem pua.
2. Hloov ntau yam thiab sijhawm
Hloov tus nqi pib: Qhov kev hloov pib tus nqi yog tus nqi ntawm qhov kev sib haum xeeb ua ntej. Tus nqi pib yog muab los ntawm nplooj ntawv harmonic ntawm nplooj ntawv dhau los thiab tsis tuaj yeem hloov kho ncaj qha. Txhawm rau hloov kho tus nqi pib no, nws yuav tsum ua tiav ntawm nplooj ntawv cov ntaub ntawv sib haum xeeb. Tus nqi pib yog sawv cev ntawm no nyob rau hauv cov nqe lus ntawm amplitude.
Hloov cov kev txwv sab saud: Cov khoom tso tawm sab saud tus nqi ntawm qhov kev hloov pauv ntau, uas ua kom ntseeg tau tias cov nqi tso tawm tsis loj dhau los ua rau cov khoom tiv thaiv puas.
Hloov lub sij hawm: Hloov lub sij hawm yog hais txog lub sij hawm luv luv ntawm txhua kauj ruam ntawm kev hloov, feem ntau yog teem me ntsis ntev dua li lub sij hawm ua hauj lwm ntawm kev tiv thaiv.
3. Harmonic sawv cev txoj kev
Cov ntaub ntawv ntawm harmonic Cheebtsam ntawm txhua theem yuav qhia tau hais tias nyob rau hauv cov nqe lus ntawm amplitude los yog ib feem pua ntawm lub hauv paus yoj. Xaiv raws li 'qhia raws li qhov feem pua ntawm qhov tseem ceeb nthwv dej ', qhov tseem ceeb ntawm txhua qhov kev sib haum xeeb hauv nplooj ntawv 'harmonics' tau nthuav tawm raws li feem pua ntawm cov amplitude ntawm lub hauv paus nthwv dej, thiab qhov amplitude kauj ruam loj ntawm qhov sib txawv kuj tau hais tias. ib feem pua ntawm cov nthwv dej hauv paus. Piv txwv li, thaum "hais raws li amplitude", yog hais tias lub amplitude ntawm lub thib ob harmonic ntawm ib tug tej yam theem voltage yog 2V thiab lub amplitude ntawm lub hauv paus nthwv dej yog 10V, ces thaum "qhia raws li ib feem ntawm lub hauv paus yoj" yog xaiv, lub tso tawm thib ob harmonic yog 20%.
