I-relay esebenza lapho ikhoyili yamanje ingaphezu kwenani elimisiwe ibizwa ngokuthi i-overcurrent relay; Kuyi-undercurrent relay. Uma i-overcurrent relay isebenza ngokujwayelekile, i-current edluliswa ikhoyili yamanje iyinani elilinganiselwe, ngakho amandla kazibuthe kagesi akhiqizwe awanele ukunqoba amandla okusabela okunwebeka; oxhumana naye ovamise ukuvaleka uhlala evaliwe. Lapho i-current ngekhoyili idlula inani elibekiwe, amandla okumunca i-electromagnetic makhulu kune-Reaction spring tension, i-iron core idonsa i-armature, ukuthintana okuvamise ukuvaleka kuyavulwa, ukuthintana okuvamise ukuvuleka kuyavalwa, ukudluliswa kwenhlawulo okudlulele kuvalwe kakhulu. isetshenziselwa izikhathi zokuqalisa ezivamile nezisindayo, njengesekhethi emfishane nokuvikela ukugcwala kakhulu kwenjini noma isekethe eyinhloko, kanye ne-undercurrent relay Evame ukusetshenziselwa ukuvikela ukukhishwa kazibuthe kwamamotho e-DC nama-chuck kazibuthe. 1-5 Isimiso sokusebenza nezici ze-thermal relay I-Thermal relay iyisekhethi yokuvikela esebenzisa umthelela oshisayo wamanje ukushintsha amasekhethi. Isetshenziswa njengokuvikela ukulayisha ngokweqile kwama-motor kusekethe. Isimiso sokusebenza se-thermal relay: lapho ukuvuthwa kwe-motor kugcwele kakhulu ngenxa yokugcwala kwamanje, ukushisa okukhiqizwa isici sokushisa kwanele ukugoba ishidi eliyinhloko le-bimetallic, futhi ipuleti lomhlahlandlela lihanjiswa kwesokudla ukuze lisunduze ishidi lesinxephezelo sokushisa. ukuzungezisa induku ye-push ezungeze i-axis Induku yokuxhuma ikhanda ihlukanisa othintana naye ohambayo kusukela kothintana naye omile, ukuze ikhoyili ye-contactor kumjikelezo we-motor ivaliwe futhi ikhululwe, futhi amandla anqanyuliwe, adlala indima yokuvikela. Ishidi lesinxephezelo sezinga lokushisa lisetshenziselwa ukunxephezela ithonya lokushisa elizungezile ekunembeni kokusebenza kwe-relay yokushisa; yenziwe ngohlobo olufanayo lweshidi le-bimetallic njengeshidi eliyinhloko le-bimetallic.
