Indima ye-slid state relays
I-Solid-state relays eneneni i-non-contact switching devices eneempawu zokudluliselwa ezisebenzisa izixhobo ze-semiconductor ukuze zithathe indawo yoqhagamshelwano lombane oluqhelekileyo njengezixhobo zokutshintsha. Isigaba esisodwa se-SSR sisixhobo esine-terminal esebenzayo, apho ii-terminals zokulawula igalelo ezimbini, ii-terminals ezimbini zokuphuma, kunye phakathi kwegalelo kunye nemveliso. Ukwahlukaniswa kwe-optical, emva kokuba i-terminal igalelo longeza i-DC okanye i-pulse signal kwixabiso elithile langoku, i-terminal ephumayo inokuguqulwa ukusuka kwi-off state ukuya kwimeko. I-relay yombuso oqinileyo ozinikeleyo unokuba nemisebenzi yokukhusela isiphaluka esifutshane, ukukhuselwa komthwalo ogqithisiweyo kunye nokukhusela ubushushu, kunye nokudibanisa i-logic yokunyanga iphakheji inokuqonda imodyuli ehlakaniphile efunwa ngumsebenzisi, enokusetyenziswa ngokuthe ngqo kwinkqubo yokulawula.
Iimpawu zeSolid State Relays
I-Solid-state relays zi-non-contact electronic switches kunye nomsebenzi wokwahlula. Akukho malungu oqhagamshelwano ngoomatshini ngexesha lenkqubo yokutshintsha. Ke ngoko, ukongeza kwimisebenzi efanayo ne-electromagnetic relays, ii-slid-state relays zikwahambelana neesekethe ezinengqondo, ezixhathisayo kwi-vibration kunye nomothuko womatshini, kwaye zineendawo zokufakela ezingenamkhawulo. , inobungqina bokufuma obulungileyo, i-mildew-proof kunye ne-anti-corrosion performance, intsebenzo egqwesileyo ekuthinteleni ukuqhuma kunye nokuthintela ukungcoliswa kwe-ozone, amandla aphantsi okufakwayo, uvakalelo oluphezulu, amandla aphantsi okulawula, ukuhambelana kakuhle kwe-electromagnetic, ingxolo ephantsi kunye nokusebenza rhoqo.

Izinto eziluncedo kunye nezingeloncedo zokuhanjiswa kombuso oqinileyo
Okokuqala, iingenelo ze-slid state relays
1. Ubomi benkonzo ephakamileyo kunye nokuthembeka okuphezulu: I-SSR ayinayo icandelo lomatshini, kwaye inezixhobo eziqinileyo zokugqiba umsebenzi woqhagamshelwano. Kuba akukho ndawo zishukumayo, inokusebenza kwindawo yokothuka kakhulu kunye nokungcangcazela. Ngenxa yobume bendalo bamacandelo abenza i-relay yombuso oqinileyo Iimpawu zimisela ubomi obude kunye nokuthembeka okuphezulu kwe-slid state relay;
2. Uvakalelo oluphezulu, amandla olawulo oluphantsi kunye nokuhambelana kakuhle kwe-electromagnetic: iireyilayi zesimo esomeleleyo zinoluhlu olubanzi lwamandla ombane kunye namandla okuqhuba aphantsi, kwaye ziyahambelana neesekethe ezininzi ezidibeneyo ezinengqondo ngaphandle kwe-buffers okanye abaqhubi;
3. Ukutshintsha ngokukhawuleza: i-relay ye-solid state isebenzisa isimo esiqinileyo, ngoko ke isantya sokutshintsha sinokuvela kwii-millisecond ezimbalwa ukuya kwii-microseconds ezimbalwa;
4. Ukuphazamiseka okuncinci kwe-electromagnetic: I-relay yesimo esiqinileyo ayinayo igalelo "coil", akukho arcing kunye ne-rebound, ngaloo ndlela inciphisa ukuphazamiseka kwe-electromagnetic. Uninzi lweereyilayi zesimo esiluqilima se-AC lutshintsho lwe-zero-voltage, oluvulwa kwi-voltage engu-0 kunye ne-zero yangoku. cima, ukunciphisa ukuphazamiseka ngokukhawuleza kwindlela yamaza yangoku, ngaloo ndlela kuncitshiswe iziphumo zokutshintsha okudlulayo.
Okwesibini, ukungalungi kwe-slid state relays
1. I-voltage drop of the tube emva kokuba i-conduction inkulu, i-voltage yangaphambili ye-thyristor okanye i-bi-phase thyristor inokufikelela kwi-1 ~ 2V, kwaye uxinzelelo lwe-saturation ye-transistor yamandla aphezulu iphakathi kwe-1 ~ 2V. I-ancestor yombane ye-conduction nayo inkulu kunokuxhatshazwa koqhagamshelwano loqhagamshelwano lomatshini;
2. Emva kokuba isixhobo se-semiconductor sivaliwe, kusekho ukuvuza kwangoku kwee-microamps ezininzi kwii-milliamps ezininzi, ngoko ke ukuhlukaniswa kombane okufanelekileyo akunakufumaneka;
3. Ngenxa yokuhla kwamandla ombane omninzi wombhobho, ukusetyenziswa kwamandla kunye nokuveliswa kobushushu emva kokuba kuqhutywe nako kukhulu, umthamo we-high-power solid state relays mkhulu kakhulu kunomnye we-electromagnetic relays yomthamo ofanayo, kwaye iindleko nazo ziphezulu;
4. Iimpawu zobushushu zamacandelo e-elektroniki kunye nobuchule bokuchasana nokuphazamiseka kweesekethe zombane zihlwempuzekile, kwaye ukuxhathisa ngemitha nako kubi. Ukuba akukho manyathelo asebenzayo athathwayo, ukuthembeka komsebenzi kuya kuba kuphantsi;
5. Iireyilayi ezizii-Solid-state zinovakalelo oluphezulu kumthwalo ogqithisileyo, kwaye kufuneka zikhuselwe ngeefusi ezikhawulezayo okanye iisekethe zokudambisa i-RC. Umthwalo we-slid-state relays ngokucacileyo unxulumene nobushushu be-ambient. Xa izinga lokushisa liphakama, umthamo womthwalo uya kuhla ngokukhawuleza.
