Imiphumela yamanje yocwaningo yokukhishwa okuyingxenye emishinini ye-GIS ikhombisa ukuthi ngenxa yamandla aphakeme kakhulu e-dielectric egesi ye-SF6, ubude besilinganiso sokukhipha ingxenye kugesi ye-SF6 enengcindezi ephezulu emishinini ye-GIS sifushane kakhulu, cishe ama-nanoseconds ambalwa, futhi ikhanda lamagagasi linesikhathi esifushane kakhulu.Isikhathi sokukhuphuka singaba yi-1ns kuphela.Lolu hlobo lwe-pulse ewumqansa olunesikhathi esifushane kakhulu, okuhlanganisa amasiginali afika ku-GHz, luzokhiqiza amaza kagesi ageleza ku-casing yemishini ye-GIS.I-high-frequency discharge pulse current igeleza ngentambo yaphansi, futhi i-casing ixhunywe phansi.Yethula i-voltage ephezulu futhi ikhiqize amagagasi kagesi endaweni ezungezile.Ukukhishwa okuyingxenye kuzophinde kubangele ukwanda okungazelelwe komfutho wegesi yesiteshi, kukhiqize amaza amade noma amagagasi e-ultrasonic egesini lemishini ye-GIS, namaza omsindo ahlukahlukene, njengamaza obude, amaza aguquguqukayo namagagasi angaphezulu, avela ensimbi. igobolondo.Ukukhishwa okuyingxenye kumishini ye-GIS nakho kungabangela igesi ye-SF6 ukuthi ibole noma ikhiphe ukukhanya.Lezi zinguquko zomphumela womzimba kanye namakhemikhali ohambisana nokukhipha ingxenye ethile ziyisisekelo sokutholwa ku-inthanethi kwemishini ye-GIS.Izindlela zokuhlonza zokukhishwa okuyingxenye kumishini ye-GIS zingahlukaniswa cishe zibe izigaba ezimbili: indlela yokuthola ugesi kanye nendlela yokutholwa okungewona ugesi.indlela, SF6 igesi ukubola umkhiqizo indlela yokuthola.
I-GDPD-300UF UHF Umtshina Wokukhipha Ingxenye
I-HV Hipot GDPD-300UF UHF partial discharge detector (i-UHF partial discharge instrument) ingasetshenziswa kabanzi ekutholeni ukukhishwa okungaphelele kwezinhlelo zamandla, okuhlanganisa i-high-voltage switchgear, iyunithi eyinhloko eyindandatho, i-voltage/i-transformer yamanje, i-transformer (kuhlanganise nokutholwa kwesimo sokushisa esomile izinto zokusebenza ezifana nama-transformers), i-GIS, imigqa engaphezulu, izintambo, njll., izinga lokukhipha impahla kagesi likalwa ngezinkomba ezilandelayo.
Izici Zomkhiqizo Zomtshina Wokukhipha Ingxenye ye-UHF
Lungiselela izinzwa ezihlukene ukuze uthole ukutholwa kokukhishwa okuyingxenye cishe kwawo wonke amathuluzi kagesi;
Isixhumi esibonakalayo esisebenziseka kalula somshini womuntu sisiza ukuphathwa kwedatha yemishini ehlukene, okuhlanganisa ukulandeleka kwamathrendi edatha yomlando, ukuhlaziya idatha evundlile neqondile, futhi ibona ukuxilongwa okuphelele okungu-360° kwemishini ehlolwayo;
Inzwa eyakhelwe ngaphakathi ye-ultrasonic kanye ne-voltage yomhlabathi yesikhashana (ngemuva kwalokhu ebizwa ngokuthi i-TEV) inzwa, engaxhunywa kuzinzwa ezikhethekile ezifana nama-transformer, i-GIS, imigqa ephezulu, nezintambo;
Indlela yokuthola engahlanyisi iyamukelwa, akukho ukwehluleka kwamandla okudingekayo ngesikhathi sokuhlolwa, futhi awukho umthombo owengeziwe onamandla kagesi aphezulu odingekayo, osebenziseka kalula kunomtshina ojwayelekile wokukhipha ingxenye ye-pulsed;
Ibanga lomkhawulokudonsa lokuhlola lingu-30kHz~2.0GHz, elifanele isimiso sokutholwa samabhendi ahlukahlukene.
