Pang'ono Kutulutsa Paintaneti Monitoring System ya GIS
Ma switch otsekera zitsulo zotsekeredwa ndi gasi (GIS) ndi mizere yotsekera zitsulo zotsekedwa ndi gasi (GIL) ndi chimodzi mwa zida zofunika kwambiri pamagetsi.Iwo ali ndi ntchito ziwiri za ulamuliro ndi chitetezo.Ngati alephera panthawi yogwira ntchito ndipo vutoli silingathe kuthetsedwa panthawi yake, lidzawononga kwambiri gululi.Kuwonongeka pang'ono ndi mtundu wamba wamtundu wa GIL/GIS.M'pofunika kugwiritsa ntchito GIS partial discharge system monitoring and error location system to monitor real-time online monitoring the GIL/GIS partial discharge signals and kupenda ndi kukonza deta yoyezedwa ndi nthawi yeniyeni kupereka chigamulo chokwanira cha malo otsekemera.Kenako ndandanda yokonza ikhoza kukonzedwa molingana ndi zotsatira zowunikira kuti mupewe ngozi zazikulu za gridi chifukwa cha kulephera kwa zida ndikuwonetsetsa kuti dongosololi likuyenda bwino ndi mtengo wocheperako.
Pali zifukwa zambiri zakuwonongeka kwa sing'anga ya dielectric, monga dzimbiri la ionization lomwe limayambitsidwa ndi malo amagetsi amphamvu kwa nthawi yayitali, kuvala kutchinjiriza komwe kumachitika chifukwa cha kugwedezeka kwamakina apamwamba, kuwonongeka kwapakatikati komwe kumachitika chifukwa cha kutentha, komanso kutchinjiriza kwa chinyezi. .Sing'anga ya dielectric imawonongeka, ndipo magwiridwe antchito amawonongeka kotero kuti kuwonongeka kwa dielectric kumakhala ndi njira yachitukuko, yomwe imapangitsa kuyang'anira pa intaneti kwa insulation kukhala kothandiza komanso kothandiza.Makinawa amagwiritsa ntchito pulogalamu ya Smart Quick yopangidwa kwathunthu ndi HVHIPOT.Imagwiritsa ntchito ukadaulo wapamwamba kwambiri wa DSP digito processing ndi mapulogalamu.Ukadaulo wowongolera umapangitsa dongosolo lathu lowunika kukhala lofulumira komanso lolondola, lomwe ndi njira yotsika mtengo komanso yodalirika yowunikira pa intaneti ya GIS.
Kudzera mu kukhazikitsa UHF sensa pa zigawo zikuluzikulu za GIL/GIS, kusonkhanitsa 500MHz-1500MHz electromagnetic mafunde chizindikiro chosangalala ndi kukhetsedwa pang'ono kwa GIL/GIS mu nthawi yeniyeni.Imasonkhanitsanso kuchuluka kwa zinthu monga matalikidwe (Q), gawo (Φ), ma frequency (N), ndi ma cycle sequence (t) ya siginecha yotulutsa pang'ono yomwe imafika pachimake pozindikira kuti kuchepetsa pafupipafupi, kuthamanga kwa sampuli ndi mayendedwe data processing buffer circuit.Mafayilo a zochitika amapangidwa ndikukwezedwa ku makina apamwamba ozindikira akatswiri apakompyuta, kuti akhazikitse mapu a zochitika ndi kuwunikira zida zowunikira.
Mfundo yoyezera ya UHF PD
Ikani sensor ya UHF pagawo la basi kapena GIL.Chojambula choyezera cha sensor chikuwonetsedwa pachithunzi pamwambapa.Kuyika kwa sensor kumagawidwa m'njira zomangidwa ndi zakunja.Masensa angapo amatha kukhazikitsidwa panthawi imodzi ya GIS kapena GIL yonse kuti mukwaniritse kuwunika koyenera kwa magawo osiyanasiyana.Sensa ya anoise imafunikanso kuti mupeze phokoso lakumbuyo ndikuliyerekeza ngati chizindikiro chakumbuyo pakuwunika kwa data.
Mfundo yoyika ya UHF partial discharge sensor ya GIL ndi yofanana ndi ya GIS ndipo imakonzedwa molingana ndi mtunda wa kufalikira kwa chizindikiro cha PD.Sensa yomangidwa imayikidwa mu njira yokhazikitsidwa kale ya GIL/GIS.Kukonzekera kwa sensa kuyenera kuwonetsetsa kuti kutulutsa pang'ono komwe kumachitika pamalo aliwonse mkati mwa GIL/GIS kumatha kuzindikirika bwino.Pansi pazimenezi, sensa iyenera kukhazikitsidwa m'magulu akuluakulu a GIL / GIS, kuphatikizapo ma circuit breakers, disconnectors, voltage transformers, mabasi, etc.
