YUAV SIV LI CAS ZINC OXIDE ARRESTER TESTER?

Thaum siv cov zinc oxide arresters mus sij hawm ntev, feem ntau cov rwb thaiv tsev yuav lwj. Sab nraud yuav zoo li qub, tab sis sab hauv tsis zoo rau kev ua haujlwm ntxiv. Yog li ntawd, nws yog ib qho tsim nyog los xyuas qhov ua tau zoo ntawm cov zinc oxide arresters raws sijhawm. Siv cov zinc oxide arrester tester, yog li yuav siv cov zinc oxide arrester tester li cas?

Cov cuab yeej ntsuas hluav taws xob zinc oxide arrester yog ib qho cuab yeej tshwj xeeb rau kev sim cov khoom siv hluav taws xob ntawm cov zinc oxide arresters. Nws yog qhov tsim nyog rau kev kuaj pom cov zinc oxide arresters ntawm ntau qib voltage uas nyob lossis tsis ua haujlwm, thiab tshawb pom cov teeb meem txaus ntshai xws li dej noo hauv cov khoom siv rwb thaiv tsev sab hauv thiab kev laus ntawm cov phaj valve.

Cov khoom siv yooj yim thiab yooj yim siv, thiab tag nrho cov txheej txheem ntawm kev ntsuas yog tswj los ntawm IPC, tag nrho cov tam sim no ntsuas, resistive tam sim no thiab nws cov harmonics MOA, zaus siv voltage thiab nws cov harmonics, lub zog nquag thiab theem, qhov tseeb voltage thiab tam sim no waveform. Cov cuab yeej siv digital waveform tsom xam, harmonic tsom xam thiab cov txiaj ntsig raug, ruaj khov digital filtering txoj kev ntawm software cuam tshuam, thiab kev tsom xam raug ntawm 3 txog 7 npaug ntawm cov ntsiab lus harmonic tseem ceeb, thiab kov yeej theem cuam tshuam, qhov tseeb theem ntawm resistance tam sim no ntsuas raws li arrester.

Yog tias lub transformer tsis ua haujlwm, thov txuas cov xov hlau av ntawm lub cuab yeej thiab lub transformer kuaj ua ntej, tom qab ntawd txuas cov xov hlau kuaj tam sim no (cov xov hlau daj, ntsuab thiab daj ntawm peb lub xov hlau tseem ceeb txuas nrog rau qhov kawg qis ntawm peb lub zinc oxide arresters), thiab thaum kawg txuas cov xov hlau kuaj voltage resistance (cov xov hlau daj, ntsuab thiab liab ntawm plaub lub xov hlau tseem ceeb txuas nrog ib kawg ntawm lub transformer ntsuas winding, thiab cov xov hlau dub txuas nrog rau lwm kawg ntawm lub transformer ntsuas winding, them sai sai rau qhov kev taw qhia, yog tias cov lus qhia tsis tuaj yeem sib phim).

Ua ke nrog cov kab xeem tam sim no, ua ntej, raws li qhov loj ntawm cov tam sim no, cov kab xeem tam sim no yog mus rau qhov ntau ntawm tus tswv tsev "0-2mA" lossis "> 2mA" (2-10mA> 2mA tus qauv nkhaus), thiab tom qab ntawd hais tias Ntawm qhov kawg ntawm txoj kev, oxide MOA raug txo qis. Txoj kev txuas cov kab xeem voltage yog txuas lub 'meter' ua ntej, thiab tom qab ntawd txuas lub transformer xeem winding. Tom qab kuaj xyuas cov xov hlau kom raug, maj mam nce qhov voltage mus rau qhov voltage ua haujlwm ntawm zinc oxide arrester, thiab tom qab ntawd ua haujlwm lub cuab yeej kom pib qhov kev xeem.
