Ukukhishwa Kwengxenye Yesistimu Yokuqapha Ku-inthanethi ye-GIS
Amaswishi ensimbi afakwe ngegesi (GIS) kanye nemigqa yokudlulisa yensimbi efakwe ngegesi (GIL) ingenye yezinto ezibaluleke kakhulu ohlelweni lwamandla.Banemisebenzi emibili yokulawula nokuvikela.Uma behlulekile ngesikhathi sokusebenza futhi inkinga ayikwazi ukuxazululwa ngesikhathi, izodala umonakalo omkhulu kugridi.Iphutha lokukhipha ingxenye liwuhlobo lwephutha elivamile le-GIL/GIS.Kuyadingeka ukusebenzisa ukuqapha okuku-inthanethi kokukhishwa kwengxenye ye-GIS kanye nesistimu yendawo enephutha ukwenza ukuqapha kwesikhathi sangempela ku-inthanethi kwamasiginali okukhipha ingxenye ye-GIL/GIS futhi uhlaziye futhi ucubungule idatha elinganisiwe kanye nesikhathi sangempela sinikeze ukwahlulela okuphelele kwesimo sokuhlukanisa.Khona-ke isimiso sokulungisa singahlelwa ngokuvumelana nemiphumela yokuqapha ukuze kugwenywe izingozi ezinkulu zegridi ezibangelwa ukwehluleka kwemishini kanye nokuqinisekisa ukusebenza okuvamile kwesistimu ngezindleko zokulungisa ezincane.
Kunezizathu eziningi zokuwohloka kwe-dielectric medium, njengokugqwala kwe-ionization okubangelwa inkambu kagesi eqinile isikhathi eside, ukugqokwa kwe-insulation okubangelwa ukudlidliza kwe-mechanical high-frequency, ukubola kokuguga kwe-medium okubangelwa imiphumela yokushisa, nokufaka umswakama. .I-dielectric medium iyonakala, futhi ukusebenza kuyehliswa ukuze ukuwohloka kwe-dielectric kube nenqubo yokuthuthukiswa, okwenza ukuqapha okuku-inthanethi kwe-insulation kusebenze futhi kuphumelele.Uhlelo lusebenzisa isofthiwe ye-Smart Quick eyakhiwe ngokuphelele yi-HVHIPOT.Isebenzisa ubuchwepheshe obusezingeni eliphezulu be-DSP bokucubungula idijithali kanye nesofthiwe.Ubuchwepheshe bokucubungula benza isistimu yethu yokuqapha isheshe futhi inembile, okuyisixazululo esiyonga kakhulu nesithembekile sohlelo lokuqapha lwe-inthanethi lwe-GIS.
Ngokufaka inzwa ye-UHF ezingxenyeni ezibalulekile ze-GIL/GIS, ukuqoqa isignali yegagasi kagesi kagesi engu-500MHz-1500MHz ejatshuliswe ukukhishwa kwengxenye kwe-GIL/GIS ngesikhathi sangempela.Iphinde iqoqe amanani esici afana ne-amplitude (Q), isigaba (Φ), imvamisa (N), nokulandelana komjikelezo (t) wesignali ye-pulse yokukhipha ingxenye efinyelela kusimo se-trigger ngokuthola isekethe yokunciphisa imvamisa, isekethe yesampula ephezulu kanye Isifunda sebhafa yokucubungula idatha.Amafayela omcimbi akhiqizwa futhi alayishwe kusistimu yokuxilongwa kochwepheshe bekhompuyutha ephezulu, ukwenza ukusungulwa kwemephu yomcimbi kanye nokuqapha ukuhlaziya isimo sokufakwa kwemishini.
Isimiso sokulinganisa se-UHF PD
Faka inzwa ye-UHF engxenyeni yebhasi noma i-GIL.Umdwebo wesimiso sokulinganisa inzwa uboniswa emfanekisweni ongenhla.Ukufakwa kwenzwa kuhlukaniswe ngamamodi akhelwe ngaphakathi nangaphandle.Izinzwa eziningi zingafakwa ngesikhathi esisodwa se-GIS noma i-GIL yonke ukuze kuzuzwe ukuqapha okusebenzayo kwezingxenye ezahlukene.Inzwa yomsindo iyadingeka ukuze uthole umsindo ongemuva futhi uwuqhathanise njengesignali yangemuva phakathi nokuhlaziywa kwedatha.
Umgomo wokufakwa kwenzwa yokukhishwa kwengxenye ye-UHF ye-GIL iyafana naleyo ye-GIS futhi ihlelwa ngokuya nezici zebanga zokusakazeka kwesignali ye-PD.Inzwa eyakhelwe ngaphakathi ifakwe ngendlela efakwe ngaphambilini yokukhiqiza kwe-GIL/GIS.Ukuhlelwa kwenzwa kufanele kuqinisekise ukuthi ukuphuma kwengxenye okwenzeka kunoma iyiphi indawo ngaphakathi kwe-GIL/GIS kungatholwa ngempumelelo.Ngaphansi kwalesi sisekelo, inzwa kufanele ifakwe ezingxenyeni ezibalulekile ze-GIL/GIS, okuhlanganisa ama-circuit breaker, izinqamuli, ama-voltage transformers, amabhasi, njll.
