Musiyano uripo pakati peHigh Voltage DC relay nesolid relay
| Chinhu chekuenzanisa | High Voltage Dc Relay | Kutumirana kwemamiriro akasimba |
| Nheyo huru | Makomputa anodhonzwa kuti avharwe/avhurwe nesimba remagineti rinogadzirwa ne electromagnetic coil, zvichiita kuti circuit ibatwe/idzimwe control. | Basa rekudzima rinoitwa zvizere kuburikidza nezvikamu zvemagetsi zve semiconductor, pasina zvikamu zvinofamba zvemakanika. Kupatsanurwa kwemasaini emagetsi uye kutonga kwesimba kunoitwa kuburikidza nema optocouplers, thyristors/MOSFETs, nezvimwewo. |
| Rated voltage range | Kazhinji yakagadzirirwa kushandiswa kwemagetsi eDC ane simba repamusoro pamusoro pe1000V, mamwe mamodheru ane simba repamusoro anogona kugamuchira masisitimu eDC ari padanho re10kV. | Masisitimu emagetsi ane simba guru (high-voltage DC) anowanzo vhara huwandu hwemagetsi hunotangira pa600V kusvika 1500V, zvigadzirwa zvishoma zviripo pamagetsi akakwira uye nekudaro mitengo yakakwira. |
| Kudonha kwesimba remagetsi | Kusagona kubata kwemagetsi emagetsi kwakaderera zvikuru (muhuwandu hwe mΩ), zvichikonzera kurasikirwa kwesimba kushoma uye kugadzirwa kwekupisa mumamiriro ekunze ane simba rakawanda. | Midziyo ye semiconductor inoratidza kudzikira kwemagetsi aripo (inenge 0.3–1V yeSi-type MOSFETs uye 1–2V yeIGBTs), zvichikonzera kugadzirwa kwekupisa kwakanyanya pasi pemamiriro ekunze akakwira. Nokudaro, dhizaini yekutarisira kupisa inofanira kuitwa. |
| Kumhanya kwekuchinja | Kufamba kwekubata kwemuchina kunoda nguva yezvikamu zvemamilisecond (kazhinji 5–50 ms) uye kunoratidza zviitiko zvinosvetuka-svetuka. | Kumhanya kwemhinduro ye microsecond-level, kusvetuka pasina kubata, kwakanakira mashandisirwo ekushandura-frequency yakawanda |
| hurefu hwehupenyu | Kubata kwemuchina kunosangana nekuora kwearc, uye hupenyu hwekuchinja mutoro hunowanzova pakati pe10^4 kusvika 10^6 cycles, nepo hupenyu hwekusava nekutakura mutoro hunogona kudarika 10^7 cycles. | Hapana kusakara kwemuchina kunoonekwa, nehupenyu hwepfungwa hunotangira pa10^8 kusvika 10^12. Hupenyu hwemuchina hunonyanya kukanganiswa nekupisa uye kushushikana kwakanyanya. |
| Kushanda kwekuzviparadzanisa nevamwe | Kuzviparadzanisa kwemuviri mushure mekubviswa kwekubatana, kuvharwa kwakanyanya kunodzivirira kupisa, uye kudonha kwemhepo kwacho kunenge kusisina kana chinhu chabuda. | Nekuda kwekupatsanurwa kwemasemiconductor junction kana optocoupler isolation, μA-leaking current iripo munzvimbo yakavhurika, zvichiita kuti isakodzere mamiriro ekuchengetedza anoda kupatsanurwa kwemagetsi zvachose. |
| Kutakura zvinhu zvakawandisa | Inoratidza kugona kwakasimba kwekuremerwa kwenguva pfupi, inokwanisa kutsungirira simba rakapetwa kagumi kupfuura simba rakatarwa kwemamirisekonzi akati wandei. | Midziyo ye semiconductor ine simba shoma rekukwanisa kuremedza magetsi, inowanzo kwanisa kutsungirira magetsi akapetwa ka1.5 kusvika kaviri pane akayerwa, uye magetsi akawandisa anogona kukonzera kukuvara zviri nyore. |
| Mamiriro ezvinhu anoshanda | Masisitimu ekuchengetera simba rine simba rakawanda, mapombi ekuchaja eDC, macircuit ekugovera magetsi ane simba rakawanda, uye mabhokisi ekugovera magetsi ane simba rakawanda emotokari itsva dzinoda mamiriro ezvinhu ane simba rakawanda uye kugona kwekushandura magetsi ane simba rakawanda. | Kudzora otomatiki kwemaindasitiri, mutemo weDC une simba shoma, nzvimbo isingaputike, mamiriro ekuchinja-chinja ane frequency yakawanda, mamiriro ekuda kuzununguka kushoma |
| Kudzora mutengo | Mutengo wacho uri pakati nepakati pamagetsi akafanana uye current rating, nepo modhi ye high-voltage uye high-current ine mutengo wakaderera kana tichienzanisa ne solid-state relay dzine ma parameter akafanana. | Mamodheru ane simba guru uye magetsi akawandisa anowedzera mitengo, uye sisitimu yekutarisira kupisa inowedzerawo mutengo wemhinduro. |
Mukushandiswa kwemagetsi ane simba guru mumotokari itsva, maDC relay ane simba guru ndiwo anonyanya kushandiswa uye akakodzera. MaSolid-state relay anoshandiswa chete mune mamwe mamiriro ekubatsira akasiyana, akadai semapoka emwenje e LED mumuviri wemotokari, ma "small-power sensor arrays", uye kudzora magonhi/mahwindo otomatiki pasina ruzha mune mamwe mamiriro emagetsi mashoma. Anonyanya kushandisa zvakanakira ma "solid-state relay", akadai sekusava neruzha rwemakanika, kumhanya kwekuchinja nekukurumidza, uye hupenyu hurefu.
Chinhu chikuru chesimba remagetsi emotokari itsva isimba remagetsi rinopfuudzwa pakati pebhatiri nemota. Zvichienzaniswa nesimba remagetsi rakaderera re12V remotokari dzechinyakare, puratifomu yemagetsi matsva emagetsi inowanzova pa400V kana kunyange 800V. Simba remagetsi rinopfuudzwa kubva kubhatiri kuenda kumota neyuniti yekudzora rinogona kusvika makumi kusvika kumazana emaampere. Saka, sechinonyanya kufungwa nezvekuchengetedza, hunhu hwemagadzirirwo emagetsi emagetsi emagetsi emagetsi emagetsi anosvika zvakanyanya padanho rekuchengetedza mota:
Marelay eDC ane voltage yepamusoro anoshandisa zvinhu zvinofambisa mhepo zvakanyanya uye magadzirirwo emagetsi akagadziridzwa kuderedza njodzi yekupisa zvakanyanya. Mushure mekunge macontacts abviswa, marelay eDC ane voltage yakawanda anogona kuita kuti pave nekuparadzaniswa kwemuviri. Voltage inotsungirira insulation inogona kusvika pamusoro pe30V, uye leakage current inenge zero, zvichidzivirira njodzi yekubuda kwemhepo ine voltage yakawanda kune vafambi uye masisitimu ane voltage shoma. Kunyange zvazvo marelay e solid-state achivimba ne semiconductor junction isolation, ane micro-ampere-level leakage current uye haakwanise kusangana nezvinodiwa zvekuchengetedza kuti circuit ine voltage yakawanda ibviswe zvachose.
Kana denderedzwa pfupi rikaitika muhurongwa hwemagetsi ane simba guru mumotokari, simba remagetsi rinongoerekana rasvika rinogona kuva rakapetwa kagumi kupfuura kukosha kwakarongwa. Simba guru rinoputika remagetsi emagetsi ane simba guru remagetsi rinowanzova zviuru zvakati wandei kana makumi ezviuru zveampere. Pamwe chete nehydrogen/hydrogen gas/magnetic blowout arc extinguishing structure yakazadzwa mu ceramic sealed enclosure, inogona kudzima arc inodziya zvakanyanya muma milliseconds uye kudzima simba remagetsi, zvichidzivirira njodzi yemoto unodziya zvishoma nezvishoma.
Madhiraivha eDC ane voltage yakawanda anowanzo tevedzera ceramic brazing kana epoxy sealing structures. Simba re ceramic breakdown rinosvika 18KV/mm, uye simba re tensile rinodarika 280Mpa. Anogona kutsungirira tembiricha yakakura (-40℃ kusvika 125℃), high-intensity vibration, uye kukanganiswa mumamiriro ezvinhu akaomarara emotokari. Dziviriro inogona kusvika IP67, uye kuvimbika kwenguva refu kwakanyanya kupfuura kwe solid-state relays.
