Uhlalutyo olufutshane lwe-GIS yeNdlela yokuFumana ukuKhupha ngokuNgaphelelanga

Iziphumo zophando zangoku zokukhutshwa kwenxalenye kwizixhobo ze-GIS zibonisa ukuba ngenxa yamandla aphezulu e-dielectric yegesi ye-SF6, ixesha lokukhupha i-pulse kwi-high-pressure ye-SF6 yegesi kwizixhobo ze-GIS lifutshane kakhulu, malunga nee-nanoseconds ezimbalwa, kwaye intloko yamaza inobude obufutshane kakhulu.Ixesha lokunyuka limalunga ne-1ns kuphela.Olu hlobo lwe-pulse engumnqantsa kunye nexesha elifutshane kakhulu, kubandakanya imiqondiso ukuya kuthi ga kwi-GHz, iya kuvelisa amaza ombane aqukuqelayo kwisingxobo sezixhobo ze-GIS.I-high-frequency discharge i-pulse current igeleza ngocingo lokumisa, kwaye i-casing ixhunyiwe phantsi.Ibonisa amandla ombane aphezulu kwaye ivelisa amaza ombane kwindawo ejikelezileyo.Ukukhutshwa okuyingxenye kuya kubangela ukwanda ngokukhawuleza koxinzelelo lwegesi yesijelo, ukuvelisa amaza amade okanye amaza e-ultrasonic kwigesi yezixhobo ze-GIS, kunye namaza ahlukeneyo omsindo, njengamaza e-longitudinal, amaza aguquguqukayo kunye namaza angaphezulu, avela kwintsimbi. iqokobhe.Ukukhutshwa okungaphelelanga kwizixhobo ze-GIS kunokubangela ukuba igesi ye-SF6 ibole okanye ikhuphe ukukhanya.Olu tshintsho lwempembelelo yomzimba kunye neekhemikhali ezihamba kunye nokukhutshwa kwenxalenye sisiseko sokufunyanwa kwe-intanethi yezixhobo ze-GIS.Iindlela zokubona ukukhutshwa kwenxalenye kwizixhobo ze-GIS zinokuhlulwa ngokufanelekileyo zibe ngamacandelo amabini: indlela yokubona umbane kunye nendlela yokufumanisa umbane ongeyena umbane.indlela, SF6 igesi ukubola imveliso indlela yokubona.

I-GDPD-300UF UHF iNqanaba yokuKhupha iDetector

I-HV Hipot GDPD-300UF UHF partial discharge detector (i-UHF partial discharge instrument) ingasetyenziswa ngokubanzi ekubhaqweni ngokuyinxenye kokukhutshwa kweenkqubo zamandla, kubandakanywa i-high-voltage switchgear, iyunithi engundoqo yeringi, i-voltage/i-transformer yangoku, i-transformer (kubandakanywa ukufunyaniswa komgangatho owomileyo we-Insulation state of izixhobo ezifana ne-transformers), i-GIS, imigca ephezulu, iintambo, njl., iqondo lokukhutshwa kwezixhobo zombane lilinganiswa ngezi zalathisi zilandelayo.

Iimpawu zeMveliso ye-UHF yokukhupha inxalenye ye-Detector

Qwalasela abenzi boluvo abahlukeneyo ukufezekisa ubhaqo lokukhupha inxalenye phantse zonke izixhobo zombane;

I-interface ye-man-friendly interface yomsebenzisi iququzelela ukulawulwa kwedatha yezixhobo ezahlukeneyo, kubandakanywa ukulandelwa kweendlela zedatha zembali, uhlalutyo lwedatha oluthe tyaba kunye noluthe nkqo, kwaye uqaphela i-360 ° yokuxilongwa ngokubanzi kwesixhobo esiphantsi kovavanyo;

I-sensor ye-ultrasonic eyakhelwe ngaphakathi kunye ne-voltage yomhlaba edlulayo (emva koku kuthiwa yi-TEV) inzwa, enokuthi idibaniswe kwiinzwa ezikhethekileyo ezifana ne-transformers, i-GIS, imigca ephezulu, kunye neentambo;

Indlela yokufumanisa engabonakaliyo iyamkelwa, akukho kusilela kwamandla okufunekayo ngexesha lovavanyo, kwaye akukho mthombo owongezelelweyo we-high-voltage ofunekayo, olungele ukusetyenziswa kunomtshini we-pulsed partial discharge detector;

Uluhlu lwe-bandwidth yovavanyo yi-30kHz ~ 2.0GHz, efanelekileyo kumgaqo-siseko wokufumanisa iibhendi ezahlukeneyo zefrikhwensi.
