Indima ye-solid state idlulisela
Ukudluliselwa kwe-Solid-state empeleni kungamadivayisi angewona othintana naye anezici zokudlulisa asebenzisa amadivaysi e-semiconductor ukuze amiselele othintana nabo kagesi bendabuko njengamadivaysi okushintsha. I-SSR yesigaba esisodwa iyisisetshenziswa esisebenzayo esinamatheminali amane, lapho amatheminali amabili okulawula okokufaka, amatheminali amabili okukhiphayo, naphakathi kokufaka nokukhiphayo. Ukuze uthole ukuhlukaniswa okubonakalayo, ngemva kokuthi itheminali yokokufaka yengeze isignali ye-DC noma i-pulse kunani elithile lamanje, itheminali yokukhiphayo ingashintshwa isuke kusimo esivaliwe iye esimweni. I-relay yesimo esiqinile esizinikele ingaba nemisebenzi yokuvikela isifunda esifushane, ukuvikela ukugcwala ngokweqile nokuvikela ukushisa ngokweqile, futhi iphakheji yokuphulukisa ye-logic ehlanganisiwe ingabona imojula ehlakaniphile edingwa umsebenzisi, engasetshenziswa ngokuqondile ohlelweni lokulawula.
Izici ze-Solid State Relays
I-Solid-state relays amaswishi kagesi angathinteki anomsebenzi wokuzihlukanisa. Azikho izingxenye zokuxhumana eziwumshini phakathi nenqubo yokushintsha. Ngakho-ke, ngaphezu kwemisebenzi efanayo nokudluliswa kwe-electromagnetic, ukudluliselwa kwe-solid-state nakho kuyahambisana namasekhethi anengqondo, amelana nokudlidliza nokushaqeka komshini, futhi kunezindawo zokufaka ezingenamkhawulo. , inomphumela omuhle wokuvikela umswakama, isikhutha kanye nokusebenza kahle kokunqanda ukugqwala, ukusebenza kahle kakhulu ekuvimbeleni ukuqhuma nokuvimbela ukungcoliswa kwe-ozone, amandla okufaka aphansi, ukuzwela okuphezulu, amandla okulawula aphansi, ukuhambisana okuhle kwe-electromagnetic, umsindo ophansi kanye nemvamisa yokusebenza ephezulu.

Izinzuzo kanye nokubi kokudluliselwa kwesimo esiqinile
Okokuqala, izinzuzo ze-solid state relays
1. Impilo yesevisi ephezulu nokuthembeka okuphezulu: I-SSR ayinazo izingxenye zemishini, futhi inamadivayisi aqinile ukuze aqedele umsebenzi wokuxhumana. Njengoba zingekho izingxenye ezihambayo, ingasebenza ezindaweni zokushaqeka okukhulu kanye nokudlidliza. Ngenxa yemvelo engokwemvelo yezingxenye ezakha i-relay yesimo esiqinile Izici zinquma impilo ende nokuthembeka okuphezulu kokudluliselwa kwesimo esiqinile;
2. Ukuzwela okuphezulu, amandla okulawula aphansi kanye nokuhambisana okuhle kwe-electromagnetic: ama-relays wesimo esiqinile anebanga elibanzi lokufakwayo lamandla kagesi namandla okushayela aphansi, futhi ahambisana namasekhethi amaningi ahlanganisiwe anengqondo ngaphandle kwamabhafa noma abashayeli;
3. Ukushintsha ngokushesha: i-solid state relay isebenzisa isimo esiqinile, ngakho-ke isivinini sokushintsha singasuka kuma-millisecond ambalwa siye kuma-microseconds ambalwa;
4. Ukuphazamiseka okuncane kazibuthe kagesi: I-solid state relay ayinakho okokufaka “ikhoyili”, ayinayo i-arcing kanye ne-rebound, ngaleyo ndlela inciphisa ukuphazamiseka kukazibuthe. Iningi le-AC eliphumayo lesimo esiqinile liwushintsho lwe-zero-voltage, oluvulwa ngo-voltage onguziro kanye noziro wamanje. cisha, kunciphisa ukuphazamiseka okungazelelwe kufomethi yamagagasi yamanje, ngaleyo ndlela kunciphisa imiphumela yokushintsha okudlulayo.
Okwesibili, ukungalungi kwe-solid state relays
1. Ukwehla kwe-voltage ye-tube ngemva kokuhanjiswa kukhulu, ukwehla kwe-voltage eya phambili ye-thyristor noma i-bi-phase thyristor ingafinyelela ku-1 ~ 2V, futhi ukucindezela kokugcwala kwe-transistor yamandla aphezulu kuphakathi kwe-1 ~ 2V. I-conduction idlozi kagesi nayo inkulu kunokumelana nokuxhumana kokuxhumana komshini;
2. Ngemuva kokuthi idivayisi ye-semiconductor icishiwe, kusengaba khona ukuvuza kwamanje kwama-microamp amaningana kuma-milliamp amaningana, ngakho-ke ukuhlukaniswa kukagesi okufanelekile akukwazi ukufezwa;
3. Ngenxa yokwehla okukhulu kwamandla kagesi weshubhu, ukusetshenziswa kwamandla kanye nokukhiqizwa kokushisa ngemva kokukhishwa nakho kukhulu, ivolumu yokudluliselwa kwesimo esiqinile samandla aphezulu mkhulu kakhulu kunaleyo yokudluliswa kwe-electromagnetic yomthamo ofanayo, futhi izindleko nazo ziphezulu;
4. Izici zokushisa zezingxenye ze-elekthronikhi kanye nekhono lokulwa nokuphazamiseka kwamasekhethi e-elekthronikhi zimbi, futhi ukumelana nemisebe nakho kubi. Uma zingekho izinyathelo ezisebenzayo ezithathwayo, ukwethembeka komsebenzi kuzoba kuphansi;
5. Ama-solid-state relay azwela kakhulu ekulayisheni ngokweqile, futhi kufanele avikelwe ama-fuse asheshayo noma amasekhethi e-RC damping. Umthwalo we-solid-state relay ngokusobala uhlobene nezinga lokushisa elizungezile. Lapho izinga lokushisa likhuphuka, umthamo womthwalo uzokwehla ngokushesha.
