GDDJ-HVC Substation Temperature Monitoring System
Pane kazhinji nzira mbiri dzekutarisisa mamiriro ekudzivirira emagetsi emagetsi emagetsi akakwira mune zviteshi: kutarisa pamhepo uye kurarama (inotakurika) online kuona.Iyo yekutanga inogona kuwana iyo hunhu paramita inoratidza abnormal insulation yemidziyo chero nguva, iri nyore kune otomatiki manejimendi.Zvisinei, mari yacho yakakura, kuiswa uye kuvaka kunonetsa, uye kugadzirisa nguva dzose kunodiwa.Kune iyo yekupedzisira, ine zvakanakira yekudyara yakaderera, yakanangwa zvakanyanya, nyore kuisa, kuchengetedza uye kugadzirisa.Chero bedzi iyo sampling unit yaiswa mumidziyo yemagetsi kumberi, kuona nguva dzose kunogona kuitwa kwemidziyo yemagetsi iri kushanda, uye kukanganisa kwekudzivirira kunogona kuwanikwa nekufamba kwenguva, kuitira kuti uwedzere nguva yepretest yekutadza simba uye kutsiva zvachose pa. -line yekutarisa nzira.
GDDJ-HVC dielectric kurasikirwa tester yehupenyu capacitive midziyo inogona kushandiswa kuyera dielectric kurasikirwa uye capacitance ye capacitive midziyo (bushing, CT, CVT, coupling capacitor), uye kuona zvikanganiso zvekudzivirira zvinobudirira.
1. Kunze kwegomba rudzi ikozvino sensor ine yakakwirira chaiyo inowanzoshandiswa panzvimbo yechinyakare sampling unit, iyo inosanganisira inodarika imwe switch yedunhu.Panguva yekuyedzwa, akawanda mapfupi ma tabo anodiwa kutungamira magumo ekudzivirira ikozvino kuyedza chiridzwa.GDDJ - HVC inoshandisa yechinyakare yakatwasuka-kuburikidza chimiro, inogona kuisirwa padyo nemidziyo, lead yemagumo ekudzivirira haina kuputswa uye kureba kwakapfupika, izvo zvinodzivirira yakavhurika dunhu rekupedzisira shielding.Iyo sensor inogona kunyatsoona masaini mukati me100μA ~ 700mA.Impedance ye sensor yakaderera, inogona kumira simba frequency ikozvino 10A uye mheni impulse ikozvino 10kA, kusangana nekushandiswa kwemamiriro ekuona online.
2. Sampling unit inotora die-casting aluminum shell sealing water design, uye inotora mvura isingapindi mvura cable connector for second output, iyo iri nyore pakubatanidza;Mushure mekunge sensor yaiswa, kazhinji haina kupihwa simba.Kuti uedze, chete tambo yechipiri yesampling unit inoda kubatanidzwa, uye "plug uye tamba" inogona kuwanikwa pasina kuvhiyiwa pamagumo ekudzivirira chiratidzo tambo.
3. Iyo yakakosha processor yechiridzwa ndeyeAmerican TI 32-bit inoyangarara-point yakakwirira performance digital signal processor (DSP), iyo inomhanyisa chaiyo-nguva yekushandisa system uye inotora yakawedzera 16-bit, yakakwirira-kumhanya, yakawanda-channel synchronous. sampling analog dhijitari inoshandura (A/D) kuona chaiyo-nguva kuyerwa uye yakakwirira-chaiyo kuverenga kwehuwandu hwakatariswa.Kugona kutarisa akawanda maturusi panguva imwe chete.
4. Nzira mbiri dzekutsvaga pa-line dzekurasikirwa kwe dielectric dzinogona kupiwa, iyo inogona kuyera dielectric kurasikirwa kusiyana uye capacitance ratio yezviviri capacitive zvishandiso muchikamu chimwe chete, uye PT yechipiri magetsi inogona kushandiswa sechiratidzo chekuyera kuyera capacitance uye dielectric. kurasikirwa kwechigadzirwa.Uchishandisa iyo yekubhadharisa yazvino sensor uye yepamusoro yedhijitari yekusefa tekinoroji, dambudziko rekurasikirwa kwedielectric kurasika uye kugadzikana rinogadziriswa, rakasanganiswa neakakwana emagetsi ekudzivirira matanho uye yepamusoro-soro tekinoroji, kusefa kwedhijitari kunogona kuona kuti dielectric kurasikirwa kwemhedzisiro bvunzo haina kukanganiswa nekukanganiswa kweharonic. uye kuvhiringidzwa kwepulse, nekunyatsoita chaiko kusvika ± 0.05%.
5. Nekuonekwa kwe dielectric kurasikirwa musiyano uye capacitance ratio ye-in-phase capacitive equipment, haigoni kungodzivisa kukanganisa kwe dielectric kurasikirwa kwechiitiko chinokonzerwa nekushandisa PT secondary voltage sechiratidzo chechiratidzo, asiwo kubatsira kuderedza simba re phase-to-phase electric field interference.
6. Iyo detector yakashongedzerwa neLCD yakakura skrini yekuratidzira yakatarisa voltage, ikozvino, dielectric kurasikirwa, resistive current, capacitive current uye mamwe data.
7. Muongorori haana kungoita basa rekutsvaga kwehupenyu, asiwo anogona kutarisa michina yepaIndaneti kwenguva yakareba, uye inonyora zvinyorwa zvakatariswa.
8. Iyo sisitimu inotora ma sensors ekunze panzvimbo ye "traditional sampling unit", iyo inogona kukwidziridzwa zviri nyore kubva "kuonekwa kwehupenyu" kuenda ku "online monitoring" pasi pekushanda kwakajairika kwemidziyo.Iko hakuna chikonzero chekubvisa ma sensor akaiswa, hapana chikonzero chekudzima mudziyo, ingo wedzera yekutarisa unit (IED).
9. Iyo detector inotora dhizaini inotakurika, iri nyore kushanda, iyo lithium bhatiri mumushini inogona kuchengetedza maawa 8 ekuenderera mberi kwekushanda nguva, inosangana zvizere nezvinodiwa zvekushandiswa kwemunda.
