(1) Cov lus teb dav dav dav thiab muaj peev xwm ntsuas kev sib haum xeeb
Qhov zoo thiab qhov tsis zoo ntawm cov yam ntxwv hloov pauv yog qhov tseem ceeb rau kev txiav txim siab seb lub tshuab hloov pauv tuaj yeem siv rau hauv lub zog hluav taws xob, tshwj xeeb tshaj yog kev sib koom tes nrog lub sijhawm ua haujlwm ntawm kev tiv thaiv relay. Traditional electromagnetic transformers muaj cov yam ntxwv tsis zoo rau cov teeb liab zaus vim muaj cov hlau cores, thiab tsis tuaj yeem cuam tshuam cov txheej txheem ncua sij hawm ntawm thawj sab. Qhov ntau zaus ntawm photoelectric transformer feem ntau yog txiav txim siab los ntawm cov khoom siv hluav taws xob hauv hluav taws xob, thiab tsis muaj teeb meem ntawm cov tub ntxhais hlau saturation, yog li nws tuaj yeem cuam tshuam qhov kev hloov pauv ntawm thawj sab. Feem ntau, nws tuaj yeem tsim los rau 0.1 Hz rau 1 MHz, thiab tshwj xeeb tuaj yeem tsim los rau 200 MHz bandpass. Cov qauv ntawm photoelectric sensor tuaj yeem ntsuas kev sib haum xeeb ntawm cov kab hluav taws xob high-voltage. Electromagnetic induction transformer yog qhov nyuaj rau kev ua tiav.
(2) Digital interface, muaj peev xwm sib txuas lus zoo
Txij li thaum lub photoelectric sensor xa cov teeb liab optical digital, nws yooj yim rau kev sib txuas nrog kev sib txuas lus, thiab tsis muaj kev ntsuas qhov yuam kev hauv kev sib kis. Nyob rau tib lub sijhawm, nrog rau kev siv dav dav ntawm microcomputerized tiv thaiv thiab tswj cov cuab yeej, photoelectric transformer tuaj yeem muab cov lej digital ncaj qha rau cov khoom siv thib ob, kom lub converter thiab A / D sampling ib feem ntawm cov khoom tiv thaiv thawj tuaj yeem raug tshem tawm, yog li ntawd. cov khoom siv thib ob tuaj yeem tau txais txiaj ntsig zoo, los txhawb kev tshawb fawb ntawm cov ntsiab lus tshiab ntawm kev tiv thaiv.
(3) Me me, lub teeb yuag, thiab yooj yim rau kev hloov kho, ua tau raws li qhov yuav tsum tau ua ntawm miniaturization thiab compactness ntawm substations
Txij li thaum photoelectric sensors cia siab rau lub taub hau sensor thiab hluav taws xob circuits rau cov teeb liab tau txais thiab ua tiav, lawv yog qhov me me thiab feem ntau hnyav dua 1000 kg. Lawv yooj yim rau kev koom ua ke hauv AIS lossis GIS. Qhov no yuav txo tau cov hneev taw ntawm lub substation zoo heev thiab ua tau raws li qhov miniaturization ntawm substation. Thiab compactness xav tau. Nyob rau tib lub sijhawm, photoelectric transformer txuas nrog cov khoom siv thib ob los ntawm qee qhov me me ntawm cov kab hluav taws xob kho qhov muag, uas tuaj yeem txo cov cable trench thiab cable zoo heev.
