Nws tsim nyog pib nrog qhov tseeb tias kev xaiv AC lossis DC rau vuam yog nyob ntawm cov txheej txheem ntawm cov electrode nws tus kheej, nrog rau cov hom hlau uas koj yuav tsum ua haujlwm. Hauv lwm lo lus, siv lub vuam hloov pauv kom tau txais qhov tam sim no tas li, thiab yog li ntawd qhov ruaj khov arc ua haujlwm nrog, tsis yog ib txwm ua tau.

Dab tsi yog qhov hloov pauv?

Lub vuam converter yog kev sib txuas ntawm ntau yam khoom siv. Nws siv kev sib xyaw ua ke ntawm AC lub cev muaj zog thiab lub tshuab tshwj xeeb DC vuam. Cov txheej txheem hloov hluav taws xob yog raws li hauv qab no. Cov hluav taws xob hluav taws xob los ntawm AC network ua rau lub tshuab hluav taws xob, ua rau cov ncej tig, tsim cov khoom siv hluav taws xob ntawm kev siv hluav taws xob hluav taws xob. Qhov no yog thawj feem ntawm kev hloov pauv. Qhov thib ob ntawm kev ua haujlwm ntawm lub vuam converter yog tias thaum lub sij hawm tig ntawm lub tshuab hluav taws xob, lub tshuab hluav taws xob generated yuav yog.tsim kom muaj hluav taws xob tas mus li.

Txawm li cas los xij, nws yuav tsum raug sau tseg tam sim ntawd tias kev siv cov khoom siv no tsis nrov heev, vim tias lawv cov txiaj ntsig qis. Tsis tas li ntawd, lub cev muaj zog muaj qhov sib hloov, uas ua rau nws tsis yooj yim rau siv.

Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm lub cuab yeej

Nws tuaj yeem raug sau tseg tias lub vuam hloov pauv yog ib hom kev vuam tshuab zoo tib yam. Luv luv hais txog kev tsim cov khoom siv no, nws yog kwv yees li hauv qab no. Muaj ob qhov tseem ceeb - qhov no yog lub tshuab hluav taws xob, uas feem ntau yog asynchronous, nrog rau lub tshuab hluav taws xob DC. Qhov peculiarity yog tias ob qho tib si ntawm cov cuab yeej no tau ua ke hauv ib rooj plaub. Nws tseem yog ib qho tseem ceeb uas yuav tau xyuam xim rau lub fact tias lub Circuit Court muaj ib tug collector. Txij li thaum lub lag luam ntawm lub tshuab hluav taws xob yog raws li electromagnetic induction, nws yuav tsim alternating tam sim no, uas yuav hloov dua siab tshiab rau tam sim no siv ib tug collector.

Yog tias peb tham txog lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm lub vuam hloov pauv, tsis txhob cuam tshuam nrog cov khoom siv xws li rectifier lossis inverter. Qhov kawg tshwm sim rau tag nrho peb cov khoom siv yog tib yam, tab sis cov ntsiab lus ntawm lawv txoj haujlwm sib txawv heev. Qhov sib txawv loj tshaj plaws yog qhov kev hloov pauv ntev dua yog nqa tawm hauv lub converter. Txij li thaum alternating tam sim no yog thawj zaug hloov mus rau hauv txhua yam zog thiab tsuas yog tom qab ntawd mus rau hauv tam sim no ncaj qha.

Koj tuaj yeem xav txog cov cuab yeej ntawm cov cuab yeej no siv qhov piv txwv ntawm ib lub chaw hloov pauv. Cov qauv zoo li no muaj cov qauv tsav asynchronous lub cev muaj zog thiab lub tshuab hluav taws xob vuam ua ke hauv ib lub tsev.

Ntawm no yog tsim nyog sau cia tias cov khoom siv no yog npaj rau kev siv sab nraum zoov. Txawm li cas los xij, lawv yuav tsum tau muab tso rau hauv qhov chaw tshwj xeeb - chav tshuab, lossis hauv qab los. Qhov no yog qhov tsim nyog los tiv thaiv cov cuab yeej hluav taws xob los ntawm nag lossis daus.

Kev npaj sab hauv ntawm chav tsev

Yog tias koj nkag mus rau hauv cov ntsiab lus ntawm cov cuab yeej thiab tsim, nrog rau cov hauv paus ntsiab lus ntawm kev ua haujlwm ntawm vuam hloov pauv, ces txhua yam zoo li qhov no.

Txij li thaum lub cuab yeej ua kom sov thaum lub sijhawm ua haujlwm, lub kiv cua tau nruab rau ntawm tus ncej ntawm lub tshuab hluav taws xob thiab lub tshuab hluav taws xob kom txias lub converter. Cov khoom siv hluav taws xob ntawm lub tshuab hluav taws xob, uas yog, nws cov ncej thiab armature, yog ua los ntawm cov ntawv nyias ntawm cov hlau ntawm qib hluav taws xob. Ntawm cov hlau nplaum ntawm cov ncej yog cov khoom xws li coils nrog windings. Lub armature, nyob rau hauv lem, muaj longitudinal grooves rau hauv uas lub insulated winding yog muab tso rau. Qhov kawg ntawm no winding yog soldered mus rau lub collector daim hlau. Tsis tas li ntawd, cov cuab yeej no muaj ballast thiab ammeter. Ob qho khoom siv nyob hauv lub thawv.

Us qauv

Tam sim no, vuam converters nrog cov ntsuas vuam tam sim no ntawm 315 A yog siv. Lub hom phiaj ntawm cov chav nyob no yog cov khoom siv ncaj qha tam sim no ntawm ib qho welding ncej. Nws kuj tseem siv tau los siv hluav taws xob phau ntawv arc vuam, surfacing thiab hlau txiav nrog stick electrodes. Hauv kev hloov pauv ntawm hom no, cov tshuab hluav taws xob ntawm GSO-300M thiab GSO-300 hom yog siv. Lawv cov cuab yeej yog plaub-ncej DC collector tshuab nrog tus kheej excitation. Qhov sib txawv ntawm ob tus qauv no los ntawm ib leeg tsuas yog nyob rau hauv qhov tseeb tias lawv muaj qhov sib txawv ntawm kev sib hloov ntawm lub tshuab hluav taws xob ncej. Qhov no yog hais txog lub vuam converter 315. 500 A yog qhov thib ob ntsuas tam sim no, uas yog siv rau kev ua haujlwm. Txawm li cas los xij, ntawm no nws yog qhov tsim nyog los txuas lub converter muaj zog dua, piv txwv li, tus qauv PD-502, ua haujlwm. Qhov sib txawv tseem ceeb ntawm tus qauv hloov pauv no thiab GSO yog tias nws muaj kev txaus siab ywj pheej. Lub ntsiab lus ntawm no yog hais tias kom lub zog ntawm PD-502, ib qho kev hloov peb-theem tam sim no yog siv, uas thawj zaug dhau los ntawm inductive-capacitive voltage converter. Ib txhij nrog lub hwj chim muaj nuj nqi, nws kuj ua raws li ib tug stabilizer rau cov qauv ntawm chav tsev.

Txawm li cas los xij, nws yog ib qho tseem ceeb kom nkag siab tias lub hom phiaj tseem ceeb ntawm lub vuam hloov pauv yog hloov lub zog ntawm cov hluav taws xob ntawm qhov hloov pauv mus rau hluav taws xob ntawm qhov xwm txheej tas li.

Type of transducers

Muaj ob hom kev hloov pauv tseem ceeb - nyob ruaj ruaj thiab txawb. Yog hais tias peb tham txog cov hom nyob ruaj ruaj, feem ntau cov no yog me me vuam cabins los yog posts tsim rau kev ua hauj lwmnrog me me. Cov welding converters ntsia ntawm no tsis muaj zog heev.

Txawb, dhau los, yog tsim los ua haujlwm nrog cov ntim loj. Lawv feem ntau yog siv los txuas cov kav dej, cov kav dej roj, cov qauv hlau, thiab lwm yam.

Nws yog ib qho tseem ceeb uas yuav tau ntxiv lwm yam txog lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm cov cuab yeej no. Raws li tau hais ua ntej - nws converts alternating tam sim no mus rau direct tam sim no siv kev hloov mus rau txhua yam zog. Txawm li cas los xij, muaj qee cov khoom siv uas tso cai rau koj los kho tus nqi ntawm cov zis DC. Cov txheej txheem hloov kho yog ua los ntawm cov khoom siv xws li ballast rheostats. Lub hauv paus ntsiab lus ntawm kev ua haujlwm yog qhov yooj yim heev - qhov siab dua tus nqi tiv thaiv, qhov tso zis DC lub zog qis dua thiab rov ua dua.

Txoj Cai Ua Haujlwm

Thaum siv lub vuam transducer, qee cov cai yuav tsum ua raws. Piv txwv li, nyob rau hauv tsis muaj qhov xwm txheej yuav tsum tau kaw cov terminals ntawm lub cuab yeej, txij li thaum lub voltage ntawm lawv yog 380/220 V. Lwm txoj cai tseem ceeb yog hais tias lub converter vaj tse yuav tsum ib txwm muaj kev ntseeg siab hauv av. Cov neeg ua haujlwm ncaj qha nrog cov cuab yeej zoo li no yuav tsum tau tiv thaiv los ntawm hnab looj tes thiab lub qhov ncauj qhov ntswg.
