Nws yog ib qho nyuaj rau kev xav txog kev tsim kho kev lag luam lossis kev tsim kho tshuab yam tsis muaj kev siv vuam. Nws muab faib ua ob hom: ncaj qha thiab hloov tam sim no.
Siv cov tam sim no ncaj qha tsim cov vuam zoo dua. Qhov no yog vim tsis muaj pes tsawg tam sim no qhov tseem ceeb, uas txhais tau hais tias lub arc burning yuav ruaj khov, spatter los ntawm cov hluav taws xob hluav taws xob txo qis, hlau nkag mus tob dua, thiab cov yam ntxwv ntawm lub zog ntawm cov vuam txhim kho.
Ntxiv rau, tsuas yog DC vuam siv tau nrog cov ntaub ntawv xws li cam khwb cia hlau, hlau alloy siab, npib tsib xee thiab tooj liab alloys, titanium.
Txhawm rau hloov pauv tam sim no muaj zaus ntawm 50 Hz rau hauv qhov tam sim no ncaj qha, siv vuam rectifier. Nws siv cov khoom siv hluav taws xob semiconductor thiab cov cuab yeej tswj tshwj xeeb hauv lub transformer. Muaj ntau hom khoom zoo li no. Txhua tus ntawm lawv muaj nyob rau hauv nws tsim ib chav tsev rectifier, ib lub ballast rau kev tiv thaiv thiab ntsuas cov cuab yeej thiab lub zog transformer.
Cov vuam rectifier yog siv rauphau ntawv arc vuam, thaum cov electrodes yaj, thiab pulsed arc vuam, nyob rau hauv uas lub mem tes pab rau kev sib cais ntawm ib tug poob ntawm cov hlau los ntawm cov hlau electrode.
Rau qhov yooj yim ntawm kev siv tshuab vuam, ib qho tshwj xeeb vuam rectifier VD ntawm hom transformer tau tsim, uas muaj cov chaw taws teeb hloov mus. Xws li converters yog tus yam ntxwv los ntawm lub ntsiab kev daws teeb meem:
- nyob rau hauv ib qho, qhov kev hloov kho tam sim no rau vuam yog du;
- sib nqus wedge txav tau shunt, kab rov tav tsim, muab kev kho kho tshuab ntawm vuam, qauv yooj yim;
- transformer windings yog ua los ntawm tooj liab;
- tsis txav windings;
- cua txias;
- ignition yog ib qho yooj yim, lub arc hlawv tsis tu ncua;
- insulation chav kawm - N;
- cov khoom txuas tam sim no muaj kev nyab xeeb thiab qhib sai;
- nyob rau hauv kev teeb tsa, hom vuam rectifier no yooj yim txav.
Qee zaum hauv tsev nws yuav tsum ua haujlwm vuam. Hauv qhov xwm txheej no, muaj ob txoj kev xaiv - yuav lub tshuab ua tiav lossis ua koj tus kheej vuam rectifier nrog koj tus kheej tes.
Lub ntsiab tseem ceeb ntawm lub tshuab hluav taws xob hauv tsev yog lub tshuab hluav taws xob tsim los hloov AC voltage hauv lub network thiab muab tus nqi thiab qhov zoo ntawm cov welded tam sim no. Nws tuaj yeem txuas nrog lub network nrog qhov hluav taws xob ntawm 220 V, thiab ntawm qhov tso zis nws yuav tsum muab 40-70 V.
Tom ntej no, koj yuav tsum tau solder lub network xaim ntawm li 2.5 square millimeters nyob rau hauv txoj kab uas hla thiab txog 5 meters ntev mus rau lub transformer terminals, kom yooj yim zog ntawm lub vuam tshuab. Cov hlau yog qhov zoo tshaj plaws siv nyob rau hauv ob chav rwb thaiv tsev.
kauj ruam tom ntej yog npaj cov cables rau vuam. Rau lub hom phiaj no, nws yog qhov zoo dua los siv cov xov hlau mos nrog cov roj hmab rwb thaiv tsev, tsawg kawg yog ob meters ntev. Thaum kawg ntawm ib lub cable peb txuas "hauv av" clip (qee zaum koj tuaj yeem siv lub tsheb "lub teeb cigarette"), nyob rau lwm lub cable - tus tuav electrode.
Tam sim no lub vuam rectifier yuav tsum tau sib dhos. Nws nyob ntawm seb lub cuab yeej yuav yooj yim npaum li cas thaum lub sijhawm ua haujlwm. Thaum lub sijhawm ua haujlwm, nws yuav ua kom sov, uas txhais tau hais tias rooj plaub yuav tsum tau ua nrog lub qhov cua. Rau kev yooj yim ntawm kev thauj mus los, peb muab cov tes tuav rau rooj plaub thiab nruab cov log. Nws tuaj yeem txhim kho cov ntsiab lus ntxiv hauv daim ntawv hooks, ntxhua khaub ncaws, cov ces kaum rau tso cov xov hlau thiab cables.
