Dab tsi yog aSolid-State Relay?
Yooj yim txhais
A Khoom-State Relay, lossis SSR, yog hom tshwj xeeb hloov. Koj siv nws los tig cov khoom siv hluav taws xob nyob rau hauv lossis tawm yam tsis muaj kev txav chaw. Es tsis txhob sib tiv thaiv hlau, SSR siv hluav taws xob zoo li cov tiaistors, triacs, lossis koj cov tub ntxhais. Cov qauv tsim no ua rau SSRS ntau nrawm dua thiab txhim khu kev ntseeg dua li cov laus-lub tshuab hluav taws xob rov qab. Koj tuaj yeem nrhiav SSRS hauv ntau cov duab thiab ntau thiab tsawg. Qee qhov haum ntawm Circuit Court cam, thaum lwm tus mount hauv kev tswj vaj huam sib luag.
Tswv yim:SSRs tsis hnav tawm sai li sai tau sai as tshuab relays vim tias lawv tsis muaj chaw txav. Qhov no txhais tau tias koj tau txais ntev-ntev li thiab quieter hloov.
Koj tuaj yeem xaiv SSRS rau cov haujlwm sib txawv. Qee qhov tuav cov cim me me, thaum lwm tus tswj cov tshuab loj. Piv txwv li, SSRs nrogCov dej kub ua ke tuaj yeem tswj tau txog 150 ampsntawm tam sim no. PCB-mounted SSRs ua haujlwm nrog txog 3 amps thiab yog qhov zoo rau teeb liab hloov. Ntawm no yog ib lub rooj uas qhia qee hom khoom:
| SSR hom | Thauj cov ntsuas tam sim no | Raug |
|---|---|---|
| Cov cua sov so | Mus txog 150 a | Tswj Panels, Cov Khoom Siv Hnyav |
| Cais Cov Hluav Taws Xob | Txog li 90 ib | Ua hauv cov khoom siv |
| Plug-in Reapay | Txog li 3 a | I / O rau cov controllers, cov khoom siv me me |
| PCB-Mounted | Txog li 3 a | Teeb liab hloov ntawm Circuit Court laug cam |
Nws ua haujlwm li cas
Thaum koj xa lub teeb liab tswj me me rau SSR, nws siv lub teeb-emitting diode (LED) sab hauv. Qhov no coj ci ntsa iab ntawm lub ntsuas, hu ua phototransistor, uas tom qab ntawd ua kom cov hloov mus. Cov txheej txheem no hu ua kev sib cais kho qhov muag. Nws ua kom muaj kev tswj hwm sab nyab xeeb los ntawm lub siab sab. Qee tus SSRS, zoo li tusMOC3041, Siv Circuit Court tshwj xeeb hu ua xoom-hla kev nrhiav tau.
Qhov no txhais tau tias cov relay hloov tsuas yog thaum AC voltage yog ze xoom. Qhov no txo cov suab nrov hluav taws xob thiab tiv thaiv koj cov cuab yeej. SSRS tuaj yeem hloov mus rau lossis tawm hauv tsuas yog1-2 milliseconds, nrawm dua li kho tshuab rov qab.
Koj yuav tsum tswj hwm kub nrog SSR. Lawv tuaj yeem tau txais kub thaum siv, yog li koj yuav tsum khaws covHlau puag hauv qab 85 degreeCov. Qee tus SSRS tuaj nrog ua kom sov sov los pab nrog qhov no. SSRS tuaj yeem ua qhov ntsuas hluav taws xob nce rau 40 V DC lossis 28 V AC, nyob ntawm tus qauv. Qhov no ua rau lawv pab tau ntau yam phiaj xwm hluav taws xob sib txawv.
AC lossis DC Khoom-State Relay: Sib Txawv Rau Qhov Tseem Ceeb
Sab hauv Cheebtsam
Sab hauv AC lossis DC khoom-lub xeev relay, koj pom ntau qhov sib txawv. Txhua hom muaj cov khoom tshwj xeeb rau nws txoj haujlwm.Ac relays siv triacCov. Ntu no tuaj yeem ua rau AC lub zog uas hloov pauv. DC cia kev siv Mosfets. Cov no yog transistors uas hloov ncaj qha tam sim no ceev thiab zoo.Ntawm no yog ib lub rooj uas qhia tau hais tias qhov sib piv ntawm qhov tseem ceeb:
| Yam | Triac-based SSRS | Mosfet-based ssrs |
|---|---|---|
| Sab hauv Cheebtsam | Triac Coupler, lub ntsiab triac, Kuj, capapitor | Cov temiconductor (Mosfets) |

| Muaj peev xwm tam sim no | Feem ntau qis dua 40 amps | Siv rau qhov muaj zog dua thiab cov ntaub ntawv DC |
| Tuav tus cwj pwm tam sim no | Tau tuav tam sim no; nyob rau ntawm kom txog thaum poob qis | Tsis tuav tam sim no; meej rau / tawm tswj |
| Hloov cov yam ntxwv | Qeeb qeeb vim tuav tam sim no | Kev hloov kho sai, tswj ntau dua |
Triacs ua haujlwm tau zoo rau AC vim tias lawv tau tig thiab tawm nrog AC yoj. Mosfets zoo dua rau DC. Lawv tsis tas yuav tam sim no tso rau xoom kom tua. Qhov no muab cov kev tswj hwm sai dua thiab muaj tseeb dua kev tswj hwm nrog DC Repays.
Tswv yim:Ib txwm khij covKev ntsuas tam sim nontawm koj cov khoom siv-lub xeev relay. An Relays nrog triacs feem ntau tswj cov khoom tsawg dua li DC ncua nrog Mosfets.
Hloov cov ntsiab cai
Yuav ua li cas AC lossis DC ruaj khov-xeev relay hloov fais fab tuag yog nyob ntawm nws tus qauv. Ac Relay siv triacs lossis rov qab-rau-rov qab therristors. Cov khoom no hloov lub nra thaum lub AC Voltage crosses xoom.
Qhov no yog hu ua xoom-cross hloov. Nws pab cov suab hluav taws xob tsawg dua thiab ua rau koj cov khoom siv muaj kev nyab xeeb. DC cia kev siv Mosfets lossis cov trantors zoo sib xws. Cov no tuaj yeem hloov lossis tawm thaum twg los tau. Qhov no muab koj tam sim thiab tswj. DC Relays tsis tos tus voltage kom ncav cuag xoom, yog li lawv hloov nrawm dua.Ntawm no yog ib lub rooj uas qhia qhov sib txawv tseem ceeb hauv kev hloov:
| Yam | Ac tau cov xeev relay (SSR) | DC Khoom Siv Lub Xeev Relay (SSR) |
|---|---|---|
| Hloov Hloov Cheebtsam | Triacs lossis rov qab-rau-rov qab thyristors (scrs) | Bipolar tistors, mosfets, lossis igbts |
| Hloov cov qauv | Xoom-hla, random, lossis ncov hloov | Transsistor-based hloov rau DC loads |
| Hloov ntsiab lus | Siv AC WURSICFICFICS; Hloov ntawm xoom hla kev | Hloov DC loads tam sim ntawd, tsis muaj xoom hla |
| Daim Ntawv Thov Kom Haum | Tsim rau AC loads | Tsim rau DC loads |
| Kev tsis sib haum | Tsis tsim nyog rau DC | Tsis tsim nyog rau AC |
Koj tsis tuaj yeem siv ib qho AC ruaj khov-lub xeev relay hloov ARC loadCov. Lub Triac sab hauv xav tau tam sim no kom poob rau xoom. Qhov no tsuas yog AC. Yog tias koj siv nws nrog DC, cov relay yuav nyob twj ywm thiab tsis tua. DC cia kev siv Mosfets. Lawv tsis tas yuav tam sim no tso rau xoom. Qhov no ua rau lawv zoo rau kev hloov DC cov khoom lag luam zoo li roj teeb lossis hnub ci ntsa iab.
