Lub luag hauj lwm ntawm solid state relays
Solid-state relays yog qhov tsis sib cuag nrog cov khoom siv sib txuas nrog cov yam ntxwv ntawm cov khoom siv hluav taws xob uas siv cov khoom siv hluav taws xob los hloov cov hluav taws xob ib txwm muaj xws li cov khoom siv hloov pauv. Ib-theem SSR yog plaub lub davhlau ya nyob twg ua haujlwm, ntawm ob lub tswv yim tswj cov khoom siv, ob lub tso zis tawm, thiab nruab nrab ntawm cov tswv yim thiab cov zis. Rau kev sib cais kho qhov muag, tom qab lub input davhlau ya nyob twg ntxiv DC lossis mem tes teeb liab rau qee tus nqi tam sim no, lub davhlau ya nyob twg tuaj yeem hloov pauv los ntawm lub xeev tawm mus rau hauv lub xeev. Lub zog ruaj khov lub xeev relay tuaj yeem muaj lub luag haujlwm ntawm kev tiv thaiv luv luv, kev tiv thaiv overload thiab tiv thaiv overheat, thiab kev sib xyaw logic curing pob tuaj yeem paub txog cov qauv ntse uas yuav tsum tau siv los ntawm tus neeg siv, uas tuaj yeem siv ncaj qha rau hauv kev tswj hwm.
Nta ntawm Solid State Relays
Solid-state relays yog cov khoom siv hluav taws xob tsis sib cuag nrog kev sib cais. Tsis muaj kev sib cuag ntawm cov neeg kho tshuab thaum lub sijhawm hloov cov txheej txheem. Yog li ntawd, nyob rau hauv tas li ntawd mus rau tib lub zog raws li electromagnetic relays, solid-state relays kuj sib xws nrog logic circuits, resistant rau vibration thiab mechanical shock, thiab muaj unlimited installation txoj hauj lwm. , muaj cov ntaub ntawv zoo noo noo-pov thawj, mildew-proof thiab anti-corrosion kev ua tau zoo, kev ua tau zoo heev hauv kev tawg-pov thawj thiab ozone kev tiv thaiv kev ua qias tuaj, tsis muaj zog input, siab rhiab heev, tsis tshua muaj hluav taws xob tswj, zoo electromagnetic compatibility, tsis tshua muaj suab nrov thiab siab khiav hauj lwm zaus.

Qhov zoo thiab qhov tsis zoo ntawm cov khoom hauv lub xeev relays
Ua ntej, qhov zoo ntawm cov khoom hauv lub xeev relays
1. Lub neej ua haujlwm siab thiab kev ntseeg siab: SSR tsis muaj cov khoom siv tshuab, thiab muaj cov khoom siv hauv lub xeev kom ua tiav cov haujlwm sib cuag. Txij li thaum tsis muaj qhov txav mus los, nws tuaj yeem ua haujlwm nyob rau hauv kev poob siab thiab kev vibration ib puag ncig. Vim yog qhov tshwm sim ntawm cov khoom uas ua rau lub xeev cov khoom relay Cov yam ntxwv txiav txim siab lub neej ntev thiab kev ntseeg siab ntawm cov khoom hauv lub xeev relay;
2. Siab rhiab heev, tsis tshua muaj kev tswj fais fab thiab zoo electromagnetic compatibility: khoom hauv lub xeev relays muaj ib tug dav input voltage ntau thiab tsawg tsav zog, thiab yog sib xws nrog feem ntau logic integrated circuits tsis muaj buffers los yog tsav tsheb;
3. Kev hloov ceev ceev: cov khoom hauv lub xeev relay siv lub xeev ruaj khov, yog li qhov kev hloov ceev tuaj yeem yog los ntawm ob peb milliseconds mus rau ob peb microseconds;
4. Kev cuam tshuam me me ntawm electromagnetic: Cov khoom hauv lub xeev relay tsis muaj "coil", tsis muaj arcing thiab rebound, yog li txo cov electromagnetic cuam tshuam. Feem ntau AC tso zis khoom lub xeev relays yog xoom-voltage hloov, uas yog qhib ntawm xoom voltage thiab xoom tam sim no. tua, txo cov kev cuam tshuam sai sai hauv cov qauv nthwv dej tam sim no, yog li txo qhov cuam tshuam ntawm kev hloov pauv hloov pauv.
Qhov thib ob, qhov tsis zoo ntawm cov khoom hauv xeev relays
1. Qhov hluav taws xob poob ntawm lub raj tom qab conduction yog qhov loj, qhov hluav taws xob rau pem hauv ntej poob ntawm thyristor lossis bi-theem thyristor tuaj yeem ncav cuag 1 ~ 2V, thiab lub siab saturation ntawm high-power transistor yog nyob nruab nrab ntawm 1 ~ 2V. Lub conduction hluav taws xob poj koob yawm txwv tseem loj dua qhov kev tiv thaiv ntawm kev sib cuag ntawm cov neeg kho tshuab;
2. Tom qab lub tshuab hluav taws xob semiconductor raug kaw, tseem tuaj yeem muaj qhov xau tam sim no ntawm ob peb lub microamps mus rau ob peb milliamps, yog li qhov zoo tshaj plaws hluav taws xob cais tsis tuaj yeem ua tiav;
3. Vim qhov loj voltage poob ntawm lub raj, lub zog noj thiab kub tiam tom qab conduction kuj loj, lub ntim ntawm high-power khoom lub xeev relays yog ntau loj dua li ntawm electromagnetic relays ntawm tib lub peev xwm, thiab tus nqi kuj yog siab;
4. Cov yam ntxwv kub ntawm cov khoom siv hluav taws xob thiab kev tiv thaiv kev cuam tshuam ntawm cov hluav taws xob hluav taws xob tsis zoo, thiab cov hluav taws xob tiv thaiv hluav taws xob kuj tsis zoo. Yog tias tsis muaj kev ntsuas ua tau zoo, kev ntseeg tau ntawm kev ua haujlwm yuav qis;
5. Solid-state relays yog cov rhiab heev rau overload, thiab yuav tsum tau tiv thaiv los ntawm ceev ceev fuses los yog RC damping circuits. Lub load ntawm solid-state relays yog pom tseeb hais tias muaj feem xyuam rau lub ambient kub. Thaum qhov kub nce, lub peev xwm thauj khoom yuav poob sai.
