1. Dab tsi yogib tug rectifier transformer?
Kev hloov pauv yog lub ntsiab lus dav dav rau peb hom kev ua haujlwm: rectification, rov qab tam sim no, thiab zaus hloov dua siab tshiab. Rectification yog qhov siv dav tshaj plaws. Cov yam ntxwv ntawm cov khoom siv rectifier yog tias cov khoom siv hluav taws xob AC yog qhov tso tawm raws li DC tom qab kho thiab lim. Lub rectifier transformer yog lub zog transformer ntawm cov khoom siv rectifier. Feem ntau cov khoom siv hluav taws xob DC rau kev lag luam siv tau los ntawm kev ntxiv lub tshuab hloov pauv rau cov khoom siv rectifier.
2. Dab tsi yoglub zog transformer?
Fais fab transformers feem ntau xa mus rau transformers uas muab lub zog rau hluav taws xob traction systems. Feem ntau cov transformers nyob rau hauv daim phiaj fais fab yog lub hwj chim transformers.
3. Qhov txawv ntawmrectifier transformersthiabfais fab mov transformers
(1) Kev ua haujlwm sib txawv
Lub luag haujlwm ntawm rectifier transformers:
1. Muab qhov tsim nyog voltage rau lub rectifier system;
2. Txo cov pa phem ntawm daim phiaj fais fab uas tshwm sim los ntawm waveform distortion los ntawm lub rectifier system.
Cov zis ntawm lub rectifier transformer tseem yog AC, nws tsuas yog muab lub zog rau cov khoom siv rectifier. Feem ntau, thawj sab yog txuas nrog lub hnub qub zoo li qub thiab sab thib ob yog txuas rau hauv cov duab delta, uas yog siv los ua kom muaj kev sib haum xeeb siab. Qhov nruab nrab ntawm qhov nruab nrab sab tsis yog grounded. Thaum cov khoom siv rectifier yog grounded ntawm ib qho chaw, nws yuav tsis ua rau cov khoom puas tsuaj, thiab lub teeb liab teeb liab yuav raug muab los ntawm cov khoom siv hauv av. Muaj kev tiv thaiv kev sib cais ntawm thawj thiab theem nrab.
Rectifier transformers feem ntau yog siv hauv electrolysis, smelting, excitation, kis tau tus mob, cascade ceev tswj, electrostatic plua plav tshem tawm, thiab high-frequency vuam. Muaj qhov sib txawv me ntsis ntawm cov qauv. Txhawm rau ua kom lub waveform du, qee qhov rectifier transformers rau electrolysis yog ua rau rau-theem outputs, thiab ib tug rau-theem rectifier choj yog ntxiv rau sab nraum kom tau ib tug kuj smooth waveform. Raws li cov yam ntxwv waveform tam sim no thiab cov kev xav tau ntawm kev sib haum xeeb ntawm thyristor rectifier Circuit Court, eddy tam sim no poob nyob rau hauv winding ntawm lub rectifier transformer, thiab cov stray poob nyob rau hauv lub structural qhov chaw, qee cov ntaub ntawv thiab cov txheej txheem yog optimized rau smelting thiab high-frequency vuam. . Qhov tseeb, cov qauv dav dav zoo ib yam.
Fais fab transformers feem ntau yog Y / Y txuas nrog nruab nrab taw tes grounding (muab ib theem fais fab mov). Yog tias siv rau cov khoom siv rectifier, thaum muaj teeb meem hauv av, cov khoom siv rectifier yuav raug puas tsuaj, thiab nws lub peev xwm los cuam tshuam cov kev txiav txim siab zoo uas tsim los ntawm cov khoom siv rectifier kuj tsis zoo.
(2) Qhov sib txawv ntawm kev siv
Lub tshuab hluav taws xob siv los ua lub zog rau cov khoom siv rectifier yog hu ua rectifier transformer. Feem ntau ntawm cov rectifier DC fais fab mov siv hauv kev lag luam yog tau los ntawm cov khoom siv rectifier uas muaj xws li rectifier transformers thiab rectifiers los ntawm AC fais fab. Nyob rau hauv lub ntiaj teb niaj hnub niaj hnub no, nws cov kev siv loj loj tuaj yeem pom ncaj qha lossis tsis ncaj hauv yuav luag txhua qhov chaw. Fais fab transformers feem ntau yog siv rau hauv lub tshuab fais fab, teeb pom kev zoo txhua hnub, thiab lub zog ntawm lub Hoobkas. Lub ntsiab siv ntawm rectifier transformers yog raws li nram no:
Electrochemical kev lag luam;
DC fais fab mov rau traction;
DC fais fab mov rau kis tau tus mob;
DC fais fab mov rau DC kis tau tus mob;
DC fais fab mov rau electroplating lossis hluav taws xob ua;
DC fais fab mov rau excitation;
DC fais fab mov rau them;
DC fais fab mov rau electrostatic plua plav tshem tawm;
4. Cov zis voltage sib txawv
(1) Qhov sib txawv ntawm lub npe
Vim yog kev sib raug zoo nrog lub rectifier, cov zis voltage ntawm lub rectifier transformer yog hu ua lub valve sab voltage, thiab nws lub npe los ntawm unidirectional conductivity ntawm diode.
(2) Qhov sib txawv ntawm txoj kev suav
Vim qhov sib txawv waveforms ntawm lub load tam sim no ntawm lub rectifier ntaus ntawv, txoj kev xam ntawm nws cov zis tam sim no tsis tsuas yog txawv heev ntawm lub hwj chim transformer tab sis kuj txawv rectifier circuits muaj ntau txoj kev xam.
5. Qhov sib txawv ntawm kev tsim thiab kev tsim khoom
Vim qhov sib txawv ntawm kev siv rectifier transformers thiab fais fab transformers, kev tsim thiab kev tsim ntawm rectifier transformers kuj txawv heev ntawm cov fais fab transformers: xav txog kev ua hauj lwm ntawm rectifier transformers, tam sim no ceev thiab sib nqus flux ceev ntawm rectifier transformers yog. ob qho tib si qis, thiab lub impedance kuj yog me ntsis loj. Nyob rau hauv cov nqe lus ntawm cov qauv ntawm winding, lub valve sab tej zaum yuav tsum tau ob windings, uas yog feem ntau muab rau pem hauv ntej thiab rov qab kis tau tus mob los yog rau pem hauv ntej kis tau tus mob thiab rov qab braking. Thaum braking, lub converter yog nyob rau hauv lub inverter ua hauj lwm lub xeev; Yog hais tias lub transformer muaj kev sib haum xeeb, ib txheej thaiv npog nrog lub davhlau ya nyob twg yuav tsum tau muab tso rau nruab nrab ntawm cov windings; ntau yam kev ntsuas xws li ntxiv dag zog rau lub phaj siab thiab nyob twj ywm, thiab nthuav cov roj channel tau txais yuav los txhim kho lub peev xwm ntawm winding los tiv thaiv luv luv circuits; Tsis tas li ntawd, cov cua kub dissipation feem ntau yog suav tias yog ntau dua li ntawm lub zog transformer thaum tsim thiab tsim khoom.
Raws li ib tug kws manufacturers ntawmrectifier transformers, peb paub zoo txog qhov tseem ceeb thiab tau cog lus los muab cov neeg siv khoom zoo thiab cov kev pabcuam zoo. Yog xav paub ntxiv, thov koj xav tiv tauj peb.
