1. Ukwethulwa kafushane kwama-relay
A udluliseyi-idivayisi yokulawula kagesiokwenza uguquko olunqunywe kusengaphambili lwesinyathelo senani elilawulwayo kumjikelezo wokuphuma kukagesi lapho inani lokokufaka (i-excitation quantity) lishintshwa ukuze lihlangabezane nezimfuneko ezishiwo.Inobudlelwano obusebenzisanayo phakathi kwesistimu yokulawula (ebuye ibizwe ngokuthi i-input circuit) kanye nesistimu elawulwayo (ebizwa nangokuthi i-output circuit).Ngokuvamile esetshenziswa kuma-circuits okulawula okuzenzakalelayo, empeleni "i-automatic switch" esebenzisa i-current encane ukulawula ukusebenza kwamandla amakhulu.Ngakho-ke, idlala indima yokulawula okuzenzakalelayo, ukuvikelwa kokuphepha kanye nesifunda sokuguqulwa kumjikelezo.
2. Indima eyinhloko yama-relay
I-Relay iyisici sokushintsha okuzenzakalelayo esinomsebenzi wokuzihlukanisa, lapho ukuguqulwa kwenjabulo kumjikelezo wokufakwayo kufinyelela inani elishiwo, kungenza umjikelezo ophumayo wamandla alawulwayo ushintshe isinyathelo esinqunyiwe kudivayisi yokulawula isifunda esizenzakalelayo.Inendlela yokuzwa yokusabela ku-excitation yangaphandle (ekagesi noma engeyona ekagesi), i-actuator ukulawula “ukuvula” kanye “nokucisha” kwesekethe elawulwayo, kanye nendlela yokuqhathanisa emaphakathi yokuqhathanisa, ukwahlulela nokuguqula ubukhulu begesi. ukuvusa amadlingozi.Ama-relay asetshenziswa kakhulu ku-remote control, telemetry, ukuxhumana, ukulawula okuzenzakalelayo, i-mechatronics, nobuchwepheshe be-aerospace ukuze ulawule, uvikele, ulawule, futhi udlulise ulwazi.
Ama-relay ngokuvamile anendlela yokungenisa (ingxenye yokokufaka) ebonisa okuguquguqukayo okuthile (njengamanje, i-voltage, amandla, i-impedance, imvamisa, izinga lokushisa, ingcindezi, isivinini, ukukhanya, njll.);i-actuator (ingxenye yokuphumayo) elawula isekethe elawulwayo “evuliwe” futhi “ivaliwe”;kanye nendlela emaphakathi (ingxenye yedrayivu) ebhangqa futhi ihlukanise inani lokufakwayo, icubungule umsebenzi futhi ishayele ingxenye yokukhiphayo phakathi kokokufaka nokukhiphayo.Phakathi kwezingxenye zokufaka nokukhiphayo ze-relay, kukhona indlela emaphakathi (ingxenye yedrayivu) ebhangqa futhi ihlukanise okokufaka, icubungule umsebenzi futhi ishayele okukhiphayo.
Njengesici sokulawula, i-relay inezindima ezimbalwa.
(1) Ukunweba ububanzi bokulawula: Isibonelo, isignali yokulawula ukudluliselwa koxhumana nabo abaningi ifike kunani elithile ingashintshwa, ivulwe futhi ivulwe amasekhethi amaningi ngesikhathi esisodwa ngokuya ngezinhlobo ezihlukene zamaqembu okuxhumana.
(2) Ukukhulisa: Isibonelo, ama-relay azwelayo, ama-relay aphakathi nendawo, njll., ngenani elincane kakhulu lokulawula, ungalawula umjikelezo wamandla aphezulu kakhulu.
(3) Amasignali ahlanganisiwe: Isibonelo, uma amasiginali okulawula amaningi efakwa ku-multi-winding relay ngendlela enqunyiwe, ayaqhathaniswa futhi ahlanganiswe ukuze azuze umphumela wokulawula onqunywe kusengaphambili.
(4) Okuzenzakalelayo, isilawuli kude, ukuqapha: Ngokwesibonelo, amalayidi emishini ezenzakalelayo, kanye nezinye izinto zikagesi, zingakha izintambo zokulawula ezihleliwe, ngaleyo ndlela zivumele ukusebenza okuzenzakalelayo.
