Solid-state relay (SSR) yog tag nrho cov hluav taws xob hluav taws xob sib xyaw ua ke ntawm cov khoom siv, cov khoom siv hluav taws xob hauv lub xeev cia siab rau cov khoom siv hluav taws xob semiconductor thiab cov khoom siv hluav taws xob ntawm cov khoom siv hluav taws xob thiab cov khoom siv kho qhov muag kom ua tiav nws cov kev sib cais thiab kev hloov pauv hloov pauv. Piv nrog cov khoom siv hluav taws xob ib txwm muaj, cov khoom siv hluav taws xob hauv lub xeev yog cov relays uas tsis muaj tshuab thiab tsis muaj qhov txav, tab sis muaj qhov tseem ceeb tib yam li electromagnetic relays.
Cov khoom hauv lub xeev relays tau siv dav hauv kev lag luam automation tswj, xws li hluav taws xob cua sov cua sov system, mature tswj machinery, chaw taws teeb tswj machinery, lub cev muaj zog, solenoid valve thiab teeb liab teeb, flicker, theem teeb pom kev zoo tswj system, khoom kho mob, tshuab luam ntawv, tshuab ntxhua khaub ncaws, hluav taws kub. kev ruaj ntseg system thiab lwm yam muaj ntau daim ntawv thov. Kev lag luam txhim khu kev qha, tsis muaj kev sib cuag, tsis muaj txim taws, lub neej ntev, tsis muaj suab nrov, tsis muaj hluav taws xob cuam tshuam, kev hloov ceev ceev, nrog lub teeb liab tswj me me kom ua tiav lub hom phiaj ntawm kev tsav tsheb loj tam sim no.
Dab tsi yog qhov txawv ntawm cov khoom hauv lub xeev relays thiab cov relay zoo tib yam
Vim yog hom teeb liab sib txawv, qhov sib txawv ntawm xoom-hloov hom thiab hom random feem ntau yog nyob rau hauv cov xwm txheej sib txawv ntawm load AC tam sim no conduction. Thaum lub teeb liab tswj tau zoo siv rau cov tswv yim, cov khoom tso tawm ntawm qhov random LSR tau hloov mus rau tam sim ntawd (ntawm qhov ceev ntawm microseconds), thaum lub load voltage ntawm xoom-hla LSR hloov mus rau tsuas yog thaum lub load voltage hla lub load. xoom hla cheeb tsam (kwv yees ± 15V). Thaum lub teeb liab tswj tau raug rho tawm los ntawm cov tswv yim, ob qho tib si xoom-hloov thiab random LSR raug muab tua thaum lub sijhawm tam sim no tsawg dua qhov kev saib xyuas tam sim no, thiab cov kev hloov pauv ntawm ob hom yog tib yam. Txawm hais tias xoom-hloov LSR tuaj yeem ua rau qhov siab tshaj plaws ib nrab-lub voj voog qeeb, nws txo qhov cuam tshuam ntawm kev thauj khoom thiab tsim RF cuam tshuam, thiab tuaj yeem tau txais qhov ua tiav sinusoidal waveform ntawm lub load, ua ib qho zoo tagnrho hloov khoom siv, uas yog dav siv nyob rau hauv lub "single-pole single-throw" switching applications. Lub LSR yog tus cwj pwm los ntawm cov tshuaj tiv thaiv ceev ceev, thiab nws tuaj yeem hloov tau yooj yim AC ua hauj lwm voltage ntawm lub load los ntawm kev tswj cov theem-hloov taw tes mem tes, yog li ntawd nws yuav siv tau rau precisely kho qhov kub thiab txias, dimming thiab lwm yam resistive loads thiab ib co inductive. loads.
