1, cov zaus hloov pauv ntawm cov microcomputer tswj hwm tus tswj hwm
Hauv kev siv cov zaus converter tswj cov kab ke, ntau cov microcomputer lossis plc tswj, yuav tsum xyuam xim rau cov zaus hloov pauv ntawm cov microcomputer tswj hwm tus tswj hwm. Vim yog tus neeg siv tus tsim qauv ntawm cov qauv microcomputer yog feem ntau cov txheej txheem kev hloov pauv, feem ntau ua rau kev tswj hwm cov haujlwm thoob ntiaj teb, yog li nws yog ib qho tsim nyog los ua kev ntsuas tsim nyog.
(1)Zoo heev. Lub cev muaj zog thiab lwm lub zog tswj cov tshuab ua kom muaj zog hauv av yuav tsum tau ua kom ncaj qha rau hauv av Busbar, cov microcomputer tswj pawg tiv thaiv av, nws yog qhov zoo tshaj rau kev sib cais. Rau qee qhov kev cuam tshuam loj, nws raug nquahu kom pom tias lub sensor, i / O interface Shielding txheej thiab tswj pawg tswj hwm tswj hwm av sib txuas.
(2)Txhawm rau cov microcomputer tswj board cov ntxaij hluav taws xob nrog emi lim, cov khoom sib xyaw dav dav, cov khoom sib nqus uas muaj zog tshaj plaws. Kev cuam tshuam cuam tshuam tuaj yeem tsim txom. Ib qho ntxiv, hauv kev cuam tshuam hluav taws xob nyob rau hauv lub sijhawm loj, xws li muaj GSM, koj tuaj yeem ntxiv cov xov tooj me me ntawm cov microcomputer tswj pawg thaiv kev tiv thaiv kev kho mob.
(3)rau zaus hloov kho lub zog EMI lim, tuaj yeem ua kom zoo rau cov kev sib txuas lus, txo cov phiaj xwm kev ua kom muaj kuab lom, txo cov txiaj ntsig zoo nkauj, cov nyhuv tag nrho yog qhov zoo. Qee lub sijhawm uas qhov kev ncua deb ntawm lub cev muaj zog thiab inverter yog ntau tshaj 100m, nws yog ib qho tsim nyog ntxiv rau cov zis mus rau hauv av xa mus rau hauv av qhov ntsuas thiab txo qis Kev cuam tshuam sab nraud hluav taws xob. Ib txoj hauv kev zoo yog siv cov yeeb nkab xov lossis thaiv cov hlau nplaum, thiab npog lub plhaub hlau steel lossis cable shield rau lub ntiaj teb kom ntseeg tau. Thov nco ntsoov tias thaum AC Producation Reactor L3 tsis ntxiv, kev siv cov yeeb nkab xov uas tau nce ntxiv ntawm cov zis rau hauv av, uas yog qhov dhau los overcurrent. Ntawm chav kawm hauv kev xyaum tsuas yog ib lossis ntau dua ntawm cov hau kev no feem ntau tau noj.
(4)Kev tiv thaiv hluav taws xob thiab kev cais ntawm qhov ntsuas qhov kev nkag siab pom thiab cov phiajcog tswj cov cim. Nyob rau hauv cov txheej txheem ntawm kev tsim qauv tswj hwm cov hloov pauv ntawm cov zaus hloov pauv, nws raug nquahu kom muaj ntau li ntau tau, tshwj xeeb tshaj yog thaum tswj kev deb yog ntau dua 1m thiab ntsia thoob plaws ntawm cov tswj hwm. Vim tias cov zaus converter feem ntau muaj ntau kauj ruam kev teeb tsa nrawm, hloov cov khoom siv ntau thiab cov zis tau ua kom tau raws li cov kev xav tau. Yog tias koj yuav tsum siv tshuaj ntsuas analog, nws raug nquahu kom siv cov hlau thaiv cable, thiab hauv sab sensor lossis inverter sab los yog inverter sab kom ua tiav cov chaw taws teeb kawg ntawm kev sib tw ntawm kev sib tw. Yog tias qhov cuam tshuam tseem muaj mob hnyav, DC / DC kev rho tawm yuav tsum tau pom. Cov qauv DC / DC module tuaj yeem siv, lossis siv V / F hloov dua siab tshiab, kho qhov muag kev cais tawm thiab tom qab ntawd siv cov txheej txheem teev cov qauv.
2, cov inverter nws tus kheej tiv thaiv kev cuam tshuam
Thaum lub zog hluav taws xob ze ntawm cov zaus hloov pauv, muaj cov hluav taws xob siab xws li siv hluav taws xob, cov twj siv hluav taws xob elevel electroly. Cov. Cov neeg siv tau pom zoo kom txais cov kev ntsuas hauv qab no.
(1) Ntxiv cov inductors thiab capacitors rau sab cov tswv yim ntawm lub inverter los tsim LC lim network.
(2) Lub hwj chim kab ntawm inverter yog muab ncaj qha los ntawm kev hloov pauv sab.
(3)Qhov twg cov neeg mob tso cai, nyias muaj nyias hloov pauv tau.
(4)Thaum sab nraud hloov cov terminals yog siv rau kev tswj hwm, nws raug pom zoo uas cov hluav thaiv cov cable siv thaum txoj kab sib txuas ntev. Thaum tswj kab thiab lub zog hluav taws xob circuit Court cuam tshuam nrog kev tswj hwm cov kab sib txuas, cov ntaub thaiv hluav taws xob yuav tsum tau thaiv ib leeg thiab tiv thaiv cov inverter malfunction.
(5)Hauv kev siv ntawm kev tswj sab nraud Yog tias txoj kab ntev dua, qhov xwm txheej ntawm kev cuam tshuam loj, nws raug nquahu kom lub V / F hloov dua siab tshiab, kev siv cov kev hais kom ua kom muaj kev tswj hwm Cov.
(6)Hauv kev siv cov chaw sib txuas lus sab nraud tswj, nws raug nquahu kom siv cov ntaub thaiv npog-khub cable, thiab qhov kev cuam tshuam loj heev, nws raug pom zoo kom txuas cov ntaub thaiv npog rau kev tswj hwm Fais fab hauv av (gnd). Txog RS232 kev sib txuas lus, them sai sai rau txoj kab tswj tsis tau tshaj 15m, koj yuav tsum tau ua kom ntev dua 15m, koj yuav tsum tau txais kev sib txuas lus ntev dua yog tsawg dua 600bps. Txog RS485 kev sib txuas lus, koj yuav tsum xav txog lub davhlau ya nyob uas tsis kam tiv taus thiab lwm yam. Rau kev siv ntawm teb cov kev tswj hwm kev nrawm nrawm, kev sib txuas lus cable yuav tsum yog cov cable tshwj xeeb, thiab kev siv ntau-kis hauv av kom txhim kho kev ntseeg tau.
3, cov teeb meem zoo
Nyob rau hauv high-zaus shock loads xws li vuam tshuab, electrolyplating fais fab mov, elotment fais fab mov thiab lwm yam, qhov hluav taws xob feem ntau, cov feem ntau flicker; Hauv kev cob qhia, muaj ntau pua cov invereters thiab lwm qhov capsacitive thauj khoom nyob rau hauv kev ua haujlwm tau muaj kuab lom loj heev rau qhov ua tau zoo heev rau cov khoom noj muaj kuab heev nws tus kheej kuj tseem muaj kev puas tsuaj heev, lossis tsis muaj kev phom sij heev Muaj peev xwm khiav tsis tu ncua thiab ib txwm muaj, lossis ua rau kev puas tsuaj rau cov tswv yim ncig ntawm cov khoom siv. Cov kev ntsuas hauv qab no tuaj yeem coj tau.
(1) Nyob rau hauv high-zaus cuam tshuam cov khoom lag luam xws li vuam tshuab, electrolyplating cov khoom siv hluav taws xob ntxiv kom txhim kho lub zog muaj zog thiab kev ua tau zoo ntawm lub hwj chim sib tshooj.
(2) Hauv lub rhiav qhov twg inverter yog feeb kom pom zoo rau kev txais yuav Kev Ntsuam Xyuas Lub Chaw Haujlwm thiab DC feem ntau lub chaw tos hluav taws xob hom. Nws raug nquahu tias cov neeg siv san txais 12-} mem tshuaj mem tes. Qhov zoo yog, kev txuag me me, txuag hluav taws xob, tshwj xeeb yog tsim nyog pib thiab ua haujlwm hluav taws xob thiab cov haujlwm hluav taws xob zoo tib yam tib lub sijhawm.
(3) Ntxiv Passive LC lim ntawm lub tswv yim sab ntawm lub inverter kom txo cov lus qhia lub hwj chim, nrog tus nqi qis, kev ntseeg siab thiab muaj txiaj ntsig zoo.
(4) Ntxiv cov khoom siv PFC nquag ntawm cov tswv yim sab ntawm cov zaus hloov kho, uas yog qhov zoo tshaj plaws, tab sis tus nqi siab dua.
