1. Incazelo ye-relay: uhlobo lwedivayisi yokulawula okuzenzakalelayo ebangela ukushintsha kwe-jump lapho inani lokokufaka (ugesi, uzibuthe, umsindo, ukukhanya, ukushisa) lifinyelela inani elithile.
1. Isimiso sokusebenza nezici zama-relay:Lapho inani lokufakwayo (elifana ne-voltage, i-current, izinga lokushisa, njll.) lifinyelela inani elishiwo, lilawula isekethe yokuphumayo ukuthi ivulwe noma ivalwe.Ama-relay angahlukaniswa ngezigaba ezimbili: ugesi (njengamanje, i-voltage, imvamisa, amandla, njll.) ama-relay kanye nokungewona ogesi (njengamazinga okushisa, ingcindezi, isivinini, njll.) ama-relay.
Banezinzuzo zesenzo esisheshayo, ukusebenza okuzinzile, impilo ende yesevisi, nosayizi omncane.Zisetshenziswa kakhulu ekuvikelweni kwamandla, ezishintshayo, ekulawuleni ukunyakaza, isilawuli kude, ukulinganisa, ukuxhumana, namanye amathuluzi.Ama-Relay awuhlobo lwedivayisi yokulawula kagesi enesistimu yokulawula (eyaziwa nangokuthi isekethe yokufaka) kanye nesistimu elawulwayo ( eyaziwa nangokuthi i-output circuit).Ngokuvamile zisetshenziswa kumasekhethi okulawula okuzenzakalelayo.
Empeleni ziwuhlobo "lwe-automatic switch" esebenzisa i-current encane ukulawula i-current enkulu.Ngakho-ke, badlala indima ekulungiseni okuzenzakalelayo, ukuvikela ukuphepha, kanye nokushintshwa kwesifunda kumjikelezo.1.Umgomo wokusebenza kanye nezici zokudluliswa kuka-electromagnetic: Ama-relay kagesi ngokuvamile ahlanganisa ama-iron cores, amakhoyili, ama-armatures, neziphethu zokuthintana.Uma nje i-voltage ethile isetshenziswa emaphethelweni amabili ekhoyili, umsinga othile uzogeleza kukhoyili, ukhiqize umphumela we-electromagnetic.
I-armature izokhangwa umgogodla wensimbi ngamandla kagesi kagesi, enqoba amandla okudonsa entwasahlobo ebuyayo, futhi ngaleyo ndlela ilethe ukuthintana okuguquguqukayo kwe-armature kanye nokuxhumana okumile (okujwayelekile ukuthintana okuvulekile) ndawonye.Lapho ikhoyili iphelelwa amandla, amandla kazibuthe kagesi ayanyamalala, futhi izikhali zibuyela endaweni yazo yasekuqaleni ngaphansi kwesenzo somthombo obuyayo, okwenza ukuthintana okuguquguqukayo kanye nokuxhumana okumile kwasekuqaleni (okuvame ukuvaleka ukuthintana) ndawonye.
Ngale ndlela, ngesenzo sokukhanga nokukhululwa, isifunda singavulwa futhi sivaliwe.Kothintana nabo "abavulekile, abavamise ukuvaleka" be-relay, bangahlukaniswa ngale ndlela: othintana naye omile esimweni esinqanyuliwe lapho ikhoyili edluliswayo inganikwa amandla ibizwa ngokuthi "ukuxhumana okuvulekile ngokujwayelekile"
