Sezvo relays ari anonyanya kushandiswa kudzora zvikamu mune zvisiri-yakajairwa otomatiki control, zvakakosha kuti unzwisiserelay kuonana zvinhuuye tarisiro yeupenyu.Kusarudza marelay ane akakodzera ekuonana zvinhu uye hurefu hwehupenyu hunogona kudzikisa mutengo wekugadzirisa uye kudzikisa mitengo yekutadza kwemidziyo.
Zvinangwa zvese uye mareyi emagetsi anowanzo kuve nehupenyu hwemagetsi hunotarisirwa kuita 100,000 maoparesheni, nepo mechanical inotarisirwa kuita 100,000, 1,000,000 kana kunyange 2.5 bhiriyoni.Chikonzero hupenyu hwemagetsi hwakadzikira zvakanyanya kana uchienzaniswa nehupenyu hwemakanika ndechekuti hupenyu hwekubata hunoenderana neapp.Mayero emagetsi anoshanda kune vanobatika vanochinja mitoro yavo yakayerwa, uye kana seti yevanobatika ichichinja mutoro mudiki pane iyo rating, hupenyu hwekubatana hunogona kunge hwakareba.Semuyenzaniso, 240A, 80V AC, 25% PF vanobatika vanogona kushandura 5A mutoro kune anopfuura zviuru zana.Nekudaro, kana aya macontacts akashandiswa pakuchinja (eg: 120A, 120VAC resistive mitoro), hupenyu hunogona kudarika miriyoni maoparesheni.Hupenyu hwemagetsi chiyero zvakare inofunga kukuvadzwa kwearc kune vanobatika, uye nekushandisa kwakaringana arc kudzvanya, hupenyu hwekuonana hunogona kuwedzerwa.
Hupenyu hwekuonana hunopera kana vanobatika vakanamira kana weld, kana kana mumwe kana vese vanobatika vakarasikirwa nezvinhu zvakawandisa uye kubatwa kwakanaka kwemagetsi hakugone kuwanikwa, semhedzisiro yekuwedzeredza kwekutamisa zvinhu panguva yekuenderera mberi nekuchinja mashandiro uye kurasikirwa kwezvinhu nekuda kwekuparadzira.
Relay contacts inowanikwa mumhando dzakasiyana-siyana dzesimbi uye alloys, saizi uye masitaera, uye kusarudzwa kwevanobatika kunoda kufunga nezvezvinhu, chiyero uye chimiro kuitira kuti isangane nezvinodiwa zveimwe application nenzira chaiyo sezvinobvira.Kutadza kuita izvi kunogona kukonzera matambudziko ekusangana kana kutadza kuonana nekukurumidza.
Zvichienderana nekushandiswa, mabatiro anogona kugadzirwa nealloys akadai sepalladium, platinamu, goridhe, sirivheri, sirivheri-nickel, uye tungsten.Kunyanya sirivheri alloy makomisheni, sirivheri cadmium oxide (AgCdO) uye sirivheri tin oxide (AgSnO), uye sirivha indium tin oxide (AgInSnO) anoshandiswa zvakanyanya muchinangwa chakajairwa uye simba relays kune yepakati kusvika kune yakakwirira ikozvino switching.
Silver Cadmium Oxide (AgCdO) yave nemukurumbira zvakanyanya nekuda kwekukukurwa kwayo kwakanakisa uye kusamira kwekutengesa pamwe nekukwira kwakanyanya kwemagetsi nekupisa. uye kusangana nekupokana padhuze neicho chesirivheri (uchishandisa zvishoma pamusoro pekubata kumanikidza), asi nekuda kweiyo inherent solder kuramba uye arc quenching zvimiro zvecadmium oxide, ine kukukurwa kwakanaka uye kuramba kwewelding.
Yakajairika AgCdO yekubata zvinhu zvine gumi kusvika 15% cadmium oxide, uye adhesion kana solder kuramba inovandudza nekuwedzera cadmium oxide zvirimo;zvisinei, nekuda kwekuderedzwa ductility, magetsi conductivity inoderera, uye kutonhora kushanda maitiro kunoderera.
Silver cadmium oxide contacts ine post-oxidation kana pre-oxidation yemhando mbiri, pre-oxidation yezvinhu mukugadzirwa kwenzvimbo yekusangana yakave nemukati oxidation, uye kupfuura iyo oxidation yepost-oxidation ine yakawedzera kufanana kugoverwa kwecadmium. oxide, iyo yekupedzisira inoita kuti iyo cadmium oxide padhuze nenzvimbo yekusangana.Post-oxidized contacts inogona kukonzera matambudziko ekutsemuka kwepamusoro kana chimiro chekubata chichifanira kushandurwa zvakanyanya mushure meoxidation, semuenzaniso, inopera kaviri, inofambisa blades, C-mhando yekubata rivets.
Silver Indium Tin Oxide (AgInSnO) pamwe neSilver Tin Oxide (AgSnO) dzave dzimwe nzira dzakanaka dzeAgCdO contacts, uye kushandiswa kwecadmium mumabatiki nemabhatiri kunorambidzwa munzvimbo zhinji dzepasi.Naizvozvo, matin oxide contacts (12%), ayo anenge 15% akaoma kupfuura AgCdO, isarudzo yakanaka.Mukuwedzera, sirivheri-indium-tin oxide contacts inokodzera kukwirisa mitoro yakakura, semuenzaniso, tungsten mwenje, uko inotsiga mamiriro ikozvino yakaderera.Kunyangwe zvakanyanya kushingirira kushambadzira, maAgInSn neAgSn anobatika ane yakakwira vhoriyamu kuramba (yakaderera conductivity) pane Ag uye AgCdO mabikirwo.Nekuda kwekuramba kwavo solder, ma contacts ari pamusoro anofarirwa zvakanyanya muindasitiri yemotokari, uko 12VDC inductive mitoro inokonzeresa kutamisa zvinhu mumaapplication aya.
