Mhedzisiro yezvino tsvagiridzo yekubuda muchidimbu mumidziyo yeGIS inoratidza kuti nekuda kwesimba rakawanda redhielectric reSF6 gasi, nguva yekubuda kwechikamu mumhepo yakakwira SF6 gasi mumidziyo yeGIS ipfupi kwazvo, ingangoita mashoma nanoseconds, uye musoro wave une nguva pfupi.Nguva yekusimuka ndeye 1ns chete.Rudzi urwu rwekupuruzira kwakadzika nekupfupika kwenguva, kusanganisira masaini anosvika kuGHz, anoburitsa mafungu emagetsi anoyerera paGIS michina casing.High-frequency discharge pulse current inoyerera nepakati waya yepasi, uye casing yakabatana pasi.Inopa yakakwira frequency voltage uye inogadzira mafungu emagetsi munzvimbo yakatenderedza.Kubuda kwechikamu kuchaitawo kuwedzera kamwe kamwe mukumanikidzwa kwegetsi gasi, kuburitsa mafungu enguva refu kana mafungu e ultrasonic mugasi remidziyo yeGIS, uye mafungu akasiyana-siyana eruzha, senge mafungu akareba, mafungu anochinjika uye masaisai epamusoro, anooneka pasimbi. shell.Kubuda kwechikamu mumidziyo yeGIS kunogonawo kukonzera SF6 gasi kuora kana kuburitsa mwenje.Idzi shanduko dzemuviri uye kemikari mhedzisiro inoperekedzwa nekubuda zvishoma ndiyo hwaro hwekuonekwa kwepamhepo kweGIS michina.Nzira dzekuona dzekubuda muchidimbu mumidziyo yeGIS dzinogona kukamurwa kuita zvikamu zviviri: nzira yekuona magetsi uye isiri-yemagetsi yekuona nzira.nzira, SF6 gasi decomposition chigadzirwa chekutsvaga nzira.
GDPD-300UF UHF Partial Discharge Detector
HV Hipot GDPD-300UF UHF partial discharge detector (UHF partial discharge instrument) inogona kushandiswa zvakanyanya muchikamu chekubuda kwemagetsi masisitimu, kusanganisira yakakwira-voltage switchgear, ring main unit, voltage/zvino transformer, transformer (inosanganisira yakaoma Insulation state yekuona midziyo yakadai sematransformer), GIS, mitsara yekumusoro, tambo, nezvimwewo, dhigirii rekubuda remidziyo yemagetsi inoyerwa nezviratidzo zvinotevera.
Zvigadzirwa zveUHF Partial Discharge Detector
Gadzirisa masensa akasiyana kuti uwane chikamu chekubuda pachena kweanenge ese midziyo yemagetsi;
Mushandisi-ane hushamwari man-machine interface inogonesa manejimendi edhata yemidziyo yakasiyana, kusanganisira kuteedzera kwenhoroondo data mafambiro, yakachinjika uye yakatwasuka data kuongororwa, uye inoziva 360 ° yakazara kuongororwa kwemidziyo iri mukuedzwa;
Yakavakwa-in ultrasonic sensor uye inotenderera pasi voltage (inozonzi TEV) sensor, iyo inogona kubatanidzwa kune yakakosha sensors senge transformers, GIS, mitsara yepamusoro, uye tambo;
Iyo isiri-invasive yekuona nzira inogamuchirwa, hapana kukundikana kwesimba kunodiwa panguva yekuyedzwa, uye hapana imwe yakakwira-voltage sosi inodiwa, iyo iri nyore kushandisa kupfuura yechinyakare pulsed partial discharge detector;
Iyo test bandwidth renji ndeye 30kHz ~ 2.0GHz, iyo inokodzera iyo yekuona musimboti weakasiyana-siyana mabhendi.
