I-Solid State Relay (SSR) isakhi esibalulekile esisetshenziswa kabanzi kuma-automation wezimboni wanamuhla wokulawulwa kwezinto zasekhaya.Ibona imisebenzi yokulawula ngamadivayisi we-semiconductor.Uma kuqhathaniswa nokudluliselwa kwemishini yendabuko, i-SSR inikeza ukwethenjwa okuphezulu, impilo yenkonzo ende nokuhambisana okungcono kwe-electromagnetic.Kodwa-ke, ukuze uqinisekise ukuthi la madivaysi e-semiconductor angasebenza ngokuqine kuzicelo ezahlukahlukene, kudingeka sinake uchungechunge lokucatshangelwa kokusetshenziswa okubalulekile.
Okokuqala, lapho sisebenzisa i-SSR ukulawula imithwalo yokuthula, ukuze siqinisekise ukuqina kwezakhi futhi kunwetshwe impilo yabo yenkonzo, kunconywa ukuthi ungavumeli umthwalo we-60% wamanje.Lokhu kungenxa yokuthi ngaphansi kwezimo eziphezulu zomthwalo, izinga lokushisa ngaphakathi kokudluliswa kwemali lizokhulisa kakhulu, lithinta ukusebenza kwalo nokwethembeka kwalo.Lapho ulawula imithwalo yokumelana nokumelana, umugqa ofanele wokuphepha uyisihluthulelo sokugcina ukusebenza kwesikhathi eside kwemishini.
Okwesibili, imithwalo ebabazekayo noma ebabazekayo, ngoba izokhiqiza i-voltage enkulu yokubuyiselwa emuva ngesikhathi senqubo yokushintsha, umthwalo onconyelwe okwamanje akufanele weqe ama-40% wenani elikalwe.Lapho ukhetha i-SSR, kubaluleke kakhulu ukukhetha umkhiqizo nge-voltage ephakeme ephezulu, ucubungule i-voltage ephezulu kakhulu ephezulu engenzeka lapho kuqalwa umthwalo ongaqondile lapho kuqalwa umthwalo ongenayo.Lokhu kuqashelwa kusiza ukunciphisa ingozi yokulimala kwemishini ngenxa yama-voltages aphezulu asheshayo.
Ngaphezu kwalokho, lapho i-SSR ivuliwe, kuzoba ne-voltage eyehlayo yonke imikhawulo yomibili, ngaleyo ndlela akhiqize ukushisa kwe-juule.Lesi simo sisobala ikakhulukazi ngaphansi kwezimo zokusebenza eziphakeme zamanje.Isibonelo, lapho okukhona njengamanje kufinyelela ku-10a, kufanele kufakwe i-radiator ukusiza ukuqeda ukushisa.Ngezimo zohlelo lokusebenza lapho okwamanje kudlula khona i-40a, ukupholisa okuphoqelekile ngabalandeli noma ukupholisa kwamanzi kungadingeka ukugcina izinga lokushisa lokusebenza lidluliselwe ekhasini eliphephile.Lezi zinyathelo ezipholile zibalulekile ukuze zilondoloze ukuqina kwe-SSR futhi kunwebe impilo yaso.
Ngaphezu kwalokho, ukweqiwa kanye nokulayisha umjikelezo omfushane kuyizimbangela zokuhluleka kwaphakade kwe-phyristor yangaphakathi ye-SSR.Ngakho-ke, lapho uklama umjikelezo, kuyadingeka ukufaka i-fuse noma i-air switch ukuze uvikele i-SSR kusuka kumjikelezo overcumpent futhi omfushane.Ngezicelo ezincane zamakhono, ama-fuses anenketho yezomnotho nesebenzayo.
