Indima yee-relay ze-solid state
Iireyi ze-Solid-state ngokwenene zizixhobo zokutshintsha ezingadibaniyo ezineempawu zereyi ezisebenzisa izixhobo ze-semiconductor ukutshintsha oonxibelelwano bombane bendabuko njengezixhobo zokutshintsha. I-SSR yesigaba esinye sisixhobo esisebenzayo esine-terminal ezine, apho iiterminal ezimbini zokulawula ukufaka, iiterminal ezimbini zokukhupha, kunye naphakathi kokufaka kunye nokuphuma. Kwi-optical isolation, emva kokuba i-terminal yokufaka yongeze isignali ye-DC okanye ye-pulse kwixabiso elithile langoku, i-terminal yokukhupha inokuguqulwa ukusuka kwimeko engaphandle ukuya kwimeko evuliweyo. I-reyi ye-solid state ezinikeleyo inokuba nemisebenzi yokukhusela i-short circuit, ukhuseleko lokugqithisa kunye nokhuseleko lobushushu obugqithisileyo, kwaye iphakheji yokudibanisa i-logic curing inokuphumeza imodyuli ekrelekrele efunekayo ngumsebenzisi, engasetyenziswa ngokuthe ngqo kwinkqubo yolawulo.
Iimpawu ze-Solid State Relays
Iireyi ze-Solid-state ziiswitshi ze-elektroniki ezingadibaniyo ezinomsebenzi wokuzihlukanisa. Akukho zixhobo zoqhagamshelwano lwe-mechanical ngexesha lenkqubo yokutshintsha. Ke ngoko, ukongeza kwimisebenzi efanayo neereyi ze-electromagnetic, iireyi ze-solid-state nazo ziyahambelana neesekethe ze-logic, ziyamelana nokungcangcazela kunye nomothuko we-mechanical, kwaye zineendawo zokufaka ezingenamda. , zisebenza kakuhle ekungangeni kumswakama, zingangeni kwi-mildew kwaye zingangeni kumhlwa, zisebenza kakuhle ekuthinteleni ukuqhuma kunye nongcoliseko lwe-ozone, amandla okufaka aphantsi, uvakalelo oluphezulu, amandla olawulo aphantsi, ukuhambelana okuhle kwe-electromagnetic, ingxolo ephantsi kunye nesantya sokusebenza esiphezulu.

Iingenelo kunye nokungalungi kwe-solid state relays
Okokuqala, iingenelo ze-solid state relays
1. Ubomi benkonzo ephezulu kunye nokuthembeka okuphezulu: I-SSR ayinazo iindawo zoomatshini, kwaye inezixhobo ze-solid-state zokugqiba umsebenzi woqhagamshelwano. Ekubeni kungekho zixhobo zishukumayo, ingasebenza kwiindawo ezishushu kakhulu kunye nokungcangcazela. Ngenxa yendalo yendalo yezixhobo ezenza i-solid state relay Iimpawu zimisela ubomi obude kunye nokuthembeka okuphezulu kwe-solid state relay;
2. Uvakalelo oluphezulu, amandla olawulo oluphantsi kunye nokuhambelana okuhle kwe-electromagnetic: ii-relay ze-solid state zinoluhlu olubanzi lwe-voltage yokufaka kunye namandla okuqhuba aphantsi, kwaye ziyahambelana neesekethe ezininzi ezidibeneyo ze-logic ezingenazo ii-buffers okanye ii-drivers;
3. Ukutshintsha ngokukhawuleza: i-relay yesimo esiqinileyo isebenzisa i-solid state, ngoko ke isantya sokutshintsha sinokusuka kwi-milliseconds ezimbalwa ukuya kwi-microseconds ezimbalwa;
4. Ukuphazamiseka okuncinci kwe-electromagnetic: I-relay ye-solid state ayinayo i-"coil" yokufaka, ayina-arcing kunye ne-rebound, ngaloo ndlela inciphisa ukuphazamiseka kwe-electromagnetic. Uninzi lwee-relay ze-solid state eziphuma kwi-AC ziyi-switch ye-zero-voltage, evulwa kwi-zero voltage kunye ne-zero current. Cima, kunciphisa ukuphazamiseka okukhawulezileyo kwi-current waveform, ngaloo ndlela kunciphisa imiphumo yokutshintsha ii-transients.
Okwesibini, iingxaki ze-solid state relays
1. Ukuhla kwe-voltage yetyhubhu emva kokuqhuba kukhulu, ukuhla kwe-voltage yangaphambili ye-thyristor okanye i-thyristor yesigaba sesibini kunokufikelela kwi-1 ~ 2V, kwaye uxinzelelo lokugcwala kwe-transistor enamandla aphezulu luphakathi kwe-1 ~ 2V. I-electrical electric ancestor nayo inkulu kune-contact resistance ye-mechanical contact;
2. Emva kokuba isixhobo se-semiconductor sicinyiwe, kusenokubakho ukuvuza komsinga wee-microamps ezininzi ukuya kwii-milliamp ezininzi, ngoko ke ukuhlukaniswa kombane okufanelekileyo akunakufezekiswa;
3. Ngenxa yokwehla okukhulu kwe-voltage yetyhubhu, ukusetyenziswa kwamandla kunye nokuveliswa kobushushu emva kokuqhuba nakho kukhulu, umthamo wee-relay ze-solid state ezinamandla aphezulu mkhulu kakhulu kunowee-relay ze-electromagnetic ezinomthamo ofanayo, kwaye ixabiso liphezulu;
4. Iimpawu zobushushu zezixhobo ze-elektroniki kunye nokukwazi ukulwa nokuphazamiseka kweesekethe ze-elektroniki azikho semgangathweni, kwaye ukumelana nemitha nako akunawo umgangatho. Ukuba akukho manyathelo asebenzayo athathwayo, ukuthembeka komsebenzi kuya kuba sezantsi;
5. Iireyila ze-Solid-state zinobuthathaka kakhulu kwi-overload, kwaye kufuneka zikhuselwe zii-fast fuses okanye ii-RC damping circuits. Umthwalo weereyila ze-solid-state ngokucacileyo unxulumene nobushushu obuphakathi. Xa ubushushu bunyuka, umthamo womthwalo uya kwehla ngokukhawuleza.
