Njengoba uzobona ngezansi, i-relay iwukushintsha okukhethekile okwenza ukwazi ukulawula i-current ene-voltage ehlukile kanye/noma umthamo kunesiginali yakho yokulawula. Njengoba zidlala indima ekuhlinzekeni ukuvikeleka, ukusebenza nokusebenza okuphephile, zibaluleke kakhulu emishinini eminingi. Amanye amadivaysi ngeke asebenze nhlobo ngaphandle kwama-relay, futhi amanye ngeke asebenze kahle noma angaba yingozi. I-Shenzhou Cable yinkampani ezinikezele ekwenzeni izintambo ezinhle nezintambo. Emabhizinisini amaningi ahlukene, kusukela ezimbonini kuya ezindaweni zokwakha, bayakwazisa ukuthi ukudluliselwa kubucayi kangakanani.
I-relay iqukethe izingxenye eziningi ezahlukene. Yakhiwe izingxenye ezintathu: ikhoyili, othintana nabo, nentwasahlobo. Lapho i-current idlula kukhoyili ikhiqiza insimu kazibuthe. Le nkundla kazibuthe idonsa abathintwayo, ivale noma ivule isekethe. Futhi ukuvula kuvimbela ukugeleza kukagesi, ukuvala isekethe kwenza kube lula. Intwasahlobo igcina oxhumana nabo besesimweni sokuqinisekisa ukuthi basebenza kahle.
I-Solid state relay: Lolu uhlobo olusha lwe-relay eyenzelwe ukushintsha ugesi kusetshenziswa amadivaysi akhethekile e-semiconductor. Yebo, ama-solid-state relay afana nama-relay ajwayelekile, kodwa awanayo into ephathekayo. Lokho kusho ukuthi ziyakwazi ukugijima ngokushesha futhi zivame ukwethembeka. Zisebenza ngamasignali edijithali, ezivumela ukuthi zivule futhi zivale ngokushesha, okulungele imishini yobuchwepheshe obuphezulu edinga ukusabela okupholile.
Kukhona okuhlukahlukene super enamelled aluminium ezisonga izintambo, ngalinye likhethelwe ukudlala indima ethile. Njengesibonelo, i-thermal overload relay isetshenziselwa ukuvikela izinjini ekushiseni ngokweqile. Uma izinga lokushisa lidlula izinga elithile, i-relay izonqamula amandla ukuvimbela umonakalo. Lokhu kubaluleke kakhulu ngoba imishini ingabhidlika noma ivuthe uma ishisa ngokweqile.
Ikhebula le-Shenzhou likhiqiza ama-relay asetshenziswa emishinini esindayo, njengaleyo etholakala ezimbonini, ezindaweni zokwakha nasezimotweni zokuthutha. Ama-relay abo akhiwe ukuze aqine, aqine, futhi asebenze kahle kuzo zonke izinhlobo zamaklayenti. Isici esiqinisekisa ukuthi imishini/izakhiwo ezisetshenziswa kuzo zisebenza ngokuqhubekayo nangempumelelo.
Ama-Ground-fault relays, athola izinkinga zikagesi kanye nama-relay okuphepha. Lawa ma-relay angakwazi ukubona amaphutha kagesi futhi asize ukuvimbela imililo noma ukushaqeka ukuthi kwenzeke. Uma kukhona okungahambi kahle, kukhona i-relay ezobulala amandla, ivumele wonke umuntu ukuthi abuyele ekhaya ngokuphepha futhi avimbele uhlelo ukuthi lungalimazi.
Ama-relay nawo ayizingxenye ezibalulekile zezinhlelo ezizenzakalelayo. Basiza nokulawula ukuhamba kukagesi ohlelweni. Olunye uhlelo lokusebenza lusebenzisa ama-relay ku-PLC (isilawuli se-logic esihlelekayo) ukudlulisa amandla ezingxenyeni ezihlukahlukene zokuzenzakalela. Lokhu kuvumela imishini ukuthi isebenzisane ngokushelela nangempumelelo.
