Khoom feature thiab daim ntawv thov

1. Ntsuas tsis muaj-load tam sim no, tsis muaj-load poob, impedance voltage, load poob, thiab xoom-ib ntu impedance rau ntau hom transformer.

2. Tsis siv neeg hloov kho waveform distortion, kho qhov kub thiab txias (muab ob qho tib si kho qhov ntsuas kub thiab cais cov kev hloov pauv ntxiv), kev kho qhov hluav taws xob (tsis muaj- ntsuas qhov ntsuas nyob rau hauv tsis yog- qhov ntsuas hluav taws xob), thiab kho tam sim no (luv- ntsuas hluav taws xob nyob rau hauv tsis yog- ntsuas tam sim no). Qhov zoo tshaj plaws rau cov chaw tsis muaj luv luv - Circuit Court kuaj muaj peev xwm rau qhov muaj peev xwm loj dua.

3. Ntsuas peb-theem voltage, peb-theem tam sim no, nruab nrab voltage, nruab nrab tam sim no, ob-theem active zog (siv dual- wattmeter txoj kev, tso saib tsuas yog A thiab C theem fais fab), thiab tag nrho lub zog.

4. Ntsuas 2nd rau 42nd harmonic cov ntsiab lus rau txhua theem voltage thiab tam sim no, nrog rau tag nrho cov distortion ratio (harmonic distortion) rau txhua lub teeb liab.

5. Qhia cov duab kos duab sib haum xeeb rau txhua theem qhov hluav taws xob thiab qhov tam sim no, muab kev nkag siab zoo ntawm cov ntsiab lus sib haum xeeb ntawm txhua zaus.

6. Kev ntsuas hluav taws xob dav dav: ntsuas qhov ntsuas hluav taws xob mus txog 750V yam tsis tas yuav tsum tau hloov ntau yam, kom ntseeg tau qhov tseeb. Kev xaiv qhov tsis raug voltage yuav tsis ua rau lub ntsuas ntsuas.

7. Lub vijtsam loj nrog cov ntawv qhia lus Askiv tag nrho thiab cov lus ceeb toom ua haujlwm ua rau tus neeg siv-kev sib raug zoo. Cov yuam sij roj hmab ua kom yooj yim ua haujlwm, thaum lub siab - brightness tseeb- xim LCD zaub tseem pom nyob rau txhua lub caij.

8. Cov neeg siv tuaj yeem luam tawm cov ntawv xeem tam sim los ntawm kev tsim - hauv tshuab luam ntawv micro.

9. Tag nrho cov txiaj ntsig kev xeem tuaj yeem khaws cia hauv cov ntawv sau tseg rau yav tom ntej siv.

10. Ua tau-nyob rau hauv tiag- lub sijhawm moos qhia hnub tim thiab lub sijhawm tam sim no, cia li khaws cov ntawv ntsuas sijhawm nrog rau cov ntaub ntawv kaw.

Kev tsim tawm cov ntsiab lus

Haum rau txhua hom kev hloov pauv, nws ntsuas qhov ntsuas tsis zoo xws li tsis muaj -load tam sim no, poob, luv- Circuit Court poob, thiab impedance voltage. Nws txhawb cov ntsiab lus sib haum xeeb, kev sib txawv ntawm tus nqi, thiab xoom- kev ntsuas impedance ib ntus, ntsib cov kev ntsuas ntsuas ntsuas raws li ntau yam kev xeem

FAQ

1) Dab tsi yog qhov ntsuas voltage thiab qhov tseeb ntawm MEBT-WII Intelligent Transformer No-Load / Load Loss Tester?

Teb: Qhov ntsuas qhov ntsuas hluav taws xob yog 0 ~ 750V nrog qhov dav - muaj peev xwm, kom ntseeg tau qhov tseeb yam tsis tas yuav hloov pauv ntau yam. Qhov ntsuas qhov ntsuas qhov tseeb yog ± 0.1%.

2) Dab tsi yog cov khoom kuaj tseem ceeb txhawb los ntawm cov cuab yeej no?

Teb: Cov kev ntsuam xyuas tseem ceeb suav nrog ib zaug -theem/three-theem tsis muaj-load testing, ib zaug-phase/three-the short-circuit testing, thiab zero-sequence impedance testing. Nws kuj ntsuas qhov ntsuas hluav taws xob (voltage, tam sim no, lub zog, zaus, thiab lwm yam), cov ntsiab lus sib haum xeeb los ntawm 2nd mus rau 42nd harmonics, thiab tag nrho cov harmonic distortion (THD). Harmonic kev faib tawm tuaj yeem pom pom los ntawm kev tsom xam spectrum.

3) Dab tsi yog qhov tseem ceeb ceev faj rau peb -theem luv- kev ntsuas hluav taws xob?

Teb: 1. Qhov qis-voltage sab yuav tsum yog luv luv-circuited siv tshwj xeeb shorting cables; txwv tsis pub, cov ntaub ntawv xeem yuav raug cuam tshuam . 2. Yog hais tias lub nplhaib- hom tam sim no transformers raug ntsia rau ntawm lub bushing ntawm lub siab -voltage los yog nruab nrab-voltage sab, lawv ob sab yuav tsum luv luv -circuited ua ntej kev sim. 3. Hlau yuav tsum nruj me ntsis raws li phau ntawv. Tag nrho cov kev xeem thaiv kev ua haujlwm yuav tsum tau ua nrog cov kab ntsuas hauv av kom tsis txhob muaj hluav taws xob poob siab los ntawm qhov hluav taws xob induced.
