Megger, tus pioneer tseeb hauv kev sim dielectric, tau cuam tshuam nrog transformers los ntawm yuav luag thaum pib. Thawj lub zog hloov hluav taws xob tau tshwm sim nyob ib puag ncig ntawm xyoo 1880s thiab qhov no tau sai sai ua raws li thawj qhov kev ntsuas kev ntsuas hluav taws xob, tsim nyob rau xyoo 1895 los ntawm Megger tus tsim Sydney Evershed.

Dab tsi yog dielectric tester?

Ib tus dielectric tester lossis hipot tester txheeb xyuas thiab ntsuas hluav taws xob rwb thaiv tsev hauv cov tswj vaj huam sib luag, transformers, hluav taws xob motors, cables thiab khoom siv hauv tsev hluav taws xob hluav taws xob substations thiab cov chaw cog cog kev lag luam siv cov ntsuas no kom tswj xyuas lawv cov khoom siv.

Koj ua li cas kuaj lub zog dielectric?

Dielectric zog yog xam los ntawm faib qhov kev tawg ntawm qhov hluav taws xob los ntawm qhov tuab ntawm tus qauv. Cov ntaub ntawv yog qhia hauv Volts/mil. Qhov chaw ntawm qhov tsis ua haujlwm tseem raug kaw. Lub zog dielectric ntau dua sawv cev rau qhov zoo ntawm cov insulator.

Hipot test yog dab tsi?

Hipot xeem yog feem ntau hom kev ntsuas hluav taws xob kev nyab xeebTsim los xyuas kom meej tias cov rwb thaiv tsev ntawm cov khoom tsim nyog txaus los tiv thaiv qhov hluav taws xob siab. Ua los ntawm kev ntxhov siab rau kev rwb thaiv tsev ntawm cov khoom deb tshaj qhov nws yuav ntsib thaum siv ib txwm. Li no, lo lus "voltage withstand test ".

Puas kuaj dielectric puas?

Lub zog dielectric ntsuas tuaj yeem ua kom puas lossis tsis muaj kev puas tsuajQee qhov kev ntsuas tus qauv xav tau daim ntawv thov ntawm lub zog loj rau cov qauv uas qhov ntsuas lub zog dielectric yog siv. Qhov no suav nrog kev puas tsuaj ntawm cov khoom siv kuaj, los ntawm carbonization ntawm cov khoom siv insulating.
