Relay ndeye yakajairwa inodzoreka switch, mumagetsi ekutonga mukati anoshandiswa zvakanyanya, nhasi isu tichanzwisisa kurongeka kwayo, yakajairika kupatsanurwa kwemhando nhatu: general relay, control relay, kuchengetedza relay.
electromagnetic relay
Chekutanga, iyo general relay ine basa rekuchinja, uye kuchengetedza basa, yakajairika electromagnetic relay uye yakasimba state relay.Electromagnetic relay zvirokwazvo imhando yemagetsi relay kazhinji ine coil, kuburikidza neiyo electromagnetic musimboti, coil magetsi kuburitsa magineti. armature inokwezvwa nemagineti, tyaira iyo yekubata chiitiko.Zvinowanzoitika ndezvekuti: kazhinji kuvhurika kusangana kwakavharwa, kazhinji kudhumhana kwepedyo kunobviswa, kana coil yadzima, armature pasi pechiito chechirimo, kazhinji yakavhurika uye kazhinji yakavharwa kusangana zvakare reset. .
solid state relay
Solid state relays ndeyekusangana switch nemagetsi maseketi mukati.Sezvinoonekwa kubva pamufananidzo uri pamusoro, imwe mugumo ndiyo yekupedzisira yekupinza, uye imwe mugumo ndiyo inobuda magumo.Iyo inobuda inopera ndeye chinja.Kuburikidza nekugadzirisa kana kutonga kwekupedzisira kwekupinza, iyo inobuda inopera uye yakavharwa uye yakavharwa.
Vaviri, iyo yakajairika yekudzora relay ndeye: yepakati relay, nguva relay, yekumhanyisa relay, kudzvanywa relay uye zvichingodaro.
nguva relay
Yepakati relays inowanzoitika uye inogona kudzora zvakananga mutoro kana zvisina kunanga simba repamusoro re AC contactor.Time relays dzinowanzo shandiswa kunonoka maseketi, seyakajairwa nyeredzi yetriangle voltage kutanga, autocoupling transformer voltage kutanga, etc.Speed relay is Inowanzo shandiswa mukureverse braking yemotor, mota iri pabraking state kumhanya yava kusvika zero, cheka magetsi womira.Iyo pressure relay inonzwa pressure, uye kubata kunofamba kana kudzvanywa kwemvura kwasvika panzvimbo yakatarwa. .
Yetatu, iyo yekudzivirira relay ndeye: thermal overload relay, ikozvino relay, voltage relay, tembiricha relay, nezvimwe.
