High Voltage DC Electromagnetic Relay

High Voltage DC Electromagnetic Relay (HVDC relay) rudzi rwechishandiso chekushandura chinoshandiswa kudzora high voltage direct current circuit, musimboti wayo mukuru wekushanda ndeyekushandisa simba remagetsi kufambisa mechanical contact kuti circuit ipinde uye ibude. Kana tichienzanisa neAC relay kana low-voltage DC relay, HVDC relay dzakasiyana mukugadzirwa uye mashandiro, kunyanya munzvimbo dzeHVDC, dzinoda kugadzirisa matambudziko makuru akadai se arc, insulation uye voltage resistance.

Musimboti wekushanda

Zvinhu zvikuru zveHVDC electromagnetic relay zvinosanganisira electromagnetic coil, iron core, armature uye mechanical contact. Kana coil yawedzerwa simba, simba re electromagnetic rinogadzirwa rinokwevera armature, zvichiita kuti mechanical contact ivhare kana kutyoka, nokudaro richidzora circuit inovhurwa nekudzima. Nekuda kwekutungamira kwemagetsi mu high voltage direct current circuit, contact yacho inowanzo gadzira continuous arc kana yabviswa, saka high voltage direct current relay inowanzo da dhizaini yekudzima arc.

Chimiro chikuru

Maumbirwo eHVDC electromagnetic relay anosanganisira zvikamu zvinotevera:
Sisitimu yemagetsi: Yakagadzirwa ne coils, iron cores uye armature, ine basa rekushandura simba remagetsi kuita simba remakanika uye kukurudzira kubata.
Sisitimu yekubata: kusanganisira kusangana kusingachinji uye kusangana kunofamba, kazhinji kunogadzirwa nezvinhu zvinodzivirira arc, zvinodzivirira kupisa kwakanyanya (senge silver alloy) kuti zvitsungirire kukurwa kwearc pasi pemhepo ine simba rakawanda.
Mudziyo wekudzima moto weArc: Nekuti arc iri mu high voltage direct current circuit yakaoma kudzimwa zvakasikwa, relay inowanzo shongedzwa ne arc extinguishing device, yakaita se magnetic blow out, vacuum arc extinguishing kana gas arc extinguishing (senge SF6 gas).
Sisitimu yekudzivirira: Kana zvinhu zviri munzvimbo ine kumanikidzwa kwakanyanya, marelay anofanirwa kunge aine simba rakanaka rekudzivirira kupisa, kazhinji achishandisa zvinhu zvinodzivirira kupisa zvakanyanya zvakaita seceramics nemapurasitiki einjiniya.
Goko: Inoshandiswa kuchengetedza chimiro chemukati, kazhinji nedhizaini yakavharwa kudzivirira guruva, hunyoro nedzimwe nzvimbo dzekunze.

Zvinhu zvehunyanzvi

HVDC electromagnetic relay ine zvinhu zvinotevera zvakakosha mukugadzira nekushanda:
Kudzivirira kwemagetsi akawanda: inogona kutsungirira zviuru zvevolts kana kunyange voltage yakakwira yeDC, yakakodzera sisitimu yeDC ine voltage yakakwira.
Kukwanisa kutakura kwakawanda kwemagetsi: Macontacts akagadzirwa kuti anotakura magetsi makuru eDC, anowanzo bva pamaamps mashoma kusvika kumazana emaamps.
Kugona kwakasimba kwekudzima arc: Kushandiswa kwetekinoroji yekudzima arc kunogona kudzivirira arc inogadzirwa kana kubatana kwacho kwabviswa, uye kuwedzera hupenyu hwerelay.
Kushanda kwakanyanya kwekudzivirira: Munzvimbo dzine magetsi akawanda, marelay anofanirwa kunge aine simba rakanaka rekudzivirira kupisa kudzivirira kuputsika kana kubuda kwemvura.
Hupenyu hwemakanika: Nekuda kwekushandiswa kwekubatana kwemagetsi, hupenyu hwadzo hunowanzo kuganhurirwa pakusakara kwekubatana uye kuputsika kwearc, kazhinji pakati pemakumi ezviuru kusvika mazana ezviuru.

Minda yekunyorera

Magetsi emagetsi emagetsi eDC ane voltage yakakwira anoshandiswa zvakanyanya muminda inotevera:
Mota dzemagetsi: Kune maDC circuits ane voltage yakakura akadai sema battery management systems (BMS), ma charging piles uye motor control.
Sisitimu yekuchengetedza simba: inoshandiswa kudzora kushaja uye kuburitsa bhatiri.
Kutapurirana kweHVDC: Inoshandiswa pakushandura nemidziyo yekudzivirira mumasisitimu ekutumira magiya eHVDC.
Midziyo yeindasitiri: Inoshandiswa mumagetsi emagetsi eDC ane voltage yakakwira, michina yemagetsi, michina yemagetsi uye zvimwe zviitiko zvemaindasitiri.
Nzvimbo itsva yesimba: Kudzora kwemagetsi emagetsi ezuva, magetsi emhepo uye mamwe masisitimu matsva esimba.
