Partial Discharge Online Monitoring System yeGIS
Gas-insulated metal-enclosed switches (GIS) uye gas-insulated metal-enclosed transmission lines (GIL) ndeimwe yemidziyo yakakosha mumagetsi emagetsi.Vane mabasa maviri ekutonga nekudzivirira.Kana vakakundikana panguva yekushanda uye dambudziko harigoni kugadziriswa nenguva, richakonzera kukanganisa kwakanyanya kune grid.Chikamu chekuburitsa mhosva ndeye yakajairika mhando yeGIL/GIS.Izvo zvinodikanwa kushandisa GIS chikamu chekuburitsa pamhepo chekutarisa uye chinokanganisa nzvimbo system kuita chaiyo-nguva yepamhepo yekutarisisa yeGIL/GIS chikamu chekuburitsa masaini uye kuongorora uye kugadzirisa iyo yakayerwa data uye chaiyo nguva inopa yakazara kutonga kwemamiriro ekudzivirira.Ipapo hurongwa hwekugadzirisa hunogona kurongwa zvinoenderana nemhedzisiro yekutarisa kudzivirira hombe dzegridi tsaona dzinokonzerwa nekutadza kwemidziyo uye kuve nechokwadi chekushanda kwakajairwa kwehurongwa nemutengo wakaderera wekugadzirisa.
Pane zvikonzero zvakawanda zvekuipa kweiyo dielectric medium, senge ionization corrosion inokonzerwa netambo yakasimba yemagetsi kwenguva yakareba, kupfeka kwekudzivirira kunokonzerwa ne mechanical high-frequency vibration, kuchembera kuparara kwepakati kunokonzerwa nekupisa kwekupisa, uye kunyungudutsa kwemvura. .Iyo dielectric svikiro yakaderedzwa, uye mashandiro acho akadzikiswa kuitira kuti dielectric iparare kuve nekuvandudza maitiro, izvo zvinoita kuti iyo on-line yekutarisisa yekuvharisa ishande uye inoshanda.Iyo sisitimu inoshandisa Smart Quick software yakagadzirwa zvachose neHVHIPOT.Inoshandisa yepamusoro-kumhanya DSP digital processing tekinoroji uye software.Iyo tekinoroji yekugadzira inoita kuti sisitimu yedu yekutarisa ikurumidze uye yakarurama, inova ndiyo yakanyanya hupfumi uye yakavimbika mhinduro yeiyo online yekutarisa system yeGIS.
Kuburikidza nekuisa UHF sensor pane zvakakosha zveGIL/GIS, kuunganidza 500MHz-1500MHz electromagnetic wave siginecha inonakidzwa nekuburitswa kwechikamu cheGIL/GIS munguva chaiyo.Inounganidzawo huwandu hunoita senge amplitude (Q), chikamu (Φ), frequency (N), uye kutenderera kutevedzana (t) kwechikamu chekuburitsa pulse siginecha iyo inosvika kune inokonzeresa mamiriro nekuona frequency kudzikisa wedunhu, kumhanyisa sampling wedunhu uye data processing buffer circuit.Mafaira echiitiko anogadzirwa uye anoiswa kune yepamusoro komputa nyanzvi yekuongorora system, kuita chiitiko mepu kumisikidzwa uye yekutarisa michina yekuisa mamiriro ekuongorora.
UHF PD kuyerwa nheyo
Isa iyo UHF sensor pane yebhazi chikamu kana GIL.Iyo sensor yekuyera nheyo dhizaini inoratidzwa mumufananidzo uri pamusoro.Iyo sensor yekumisikidza yakakamurwa kuva akavakirwa-mukati uye ekunze modhi.Multiple sensors inogona kuiswa pane imwe GIS kupindirana kana iyo GIL yese kuti iwane kunyatso tarisisa kwezvikamu zvakasiyana.Anoise sensor inodiwa kuti uwane iyo yekumashure ruzha uye kuienzanisa sechiratidzo chekumashure panguva yekuongorora data.
Iyo yekuisa musimboti weiyo UHF partial discharge sensor yeGIL yakafanana neiyo yeGIS uye yakarongedzwa zvinoenderana neakareba maitiro ePD chiratidzo chekuparadzira.Iyo yakavakirwa-mukati sensor yakaiswa mune pre-yakaiswa nzira yeGIL/GIS kugadzirwa.Iyo sensor kurongeka kunofanirwa kuve nechokwadi chekuti kubuda kwechidimbu kunoitika pane chero chinzvimbo mukati meGIL/GIS kunogona kunyatsoonekwa.Pasi pechinhu ichi, sensor inofanirwa kuiswa muzvikamu zvakakosha zveGIL/GIS, zvinosanganisira mabreaker breaker, disconnectors, voltage transformers, busbars, etc.
