Transformer Winding Deformation Analysis yog dab tsi?
Transformer Winding Deformation Analysis(SFRA) kev sim siv cov cuab yeej tshwj xeeb los ntsuas ob qho tib si txhua yam thiab hluav taws xob kev ncaj ncees nyob rau hauv lub zog transformers, reactors, thiab cov khoom siv inductive. Txoj hauv kev no sib txawv los ntawm kev ntsuas kev ntsuas hluav taws xob zoo los ntawm kev tshuaj xyuas seb lub tshuab hluav taws xob windings coj tus cwj pwm li cas hla ntau zaus ntau dua li kev ntes cov kev tiv thaiv yooj yim lossis cov duab capacitance.
Cov txheej txheem so ntawm kev kho cov transformer windings raws li sophisticated RLC tes hauj lwm. Cov kev sib txuas ua ke no tsim cov kab lus teb sib txawv -plotting amplitude thiab theem tawm tsam zaus- uas tsim cov ntiv tes hauv paus rau ib tus neeg. Kev cuam tshuam ntawm lub cev sab hauv, txawm tias raug cuam tshuam los ntawm luv luv - Circuit Court mechanical stresses ua rau winding displacement, core realignment, los yog degraded clamping siab, inevitably reshape lub inductance inductance thiab capacitance. Cov kev hloov pauv no sau npe raws li ntsuas tau hloov pauv hauv cov lus teb zaus kos npe.
Cov txheej txheem xeem suav nrog cheb qhov qis -voltage sinusoidal teeb liab los ntawm kev nthuav dav spectrum, feem ntau hla 20 Hz mus rau 2 MHz lossis dhau mus, thaum ntes cov txiaj ntsig cov txiaj ntsig. Cov txheej txheem no ua tiav qhov tshwj xeeb rhiab heev hauv kev nthuav tawm qhov hloov pauv geometric hloov pauv hauv lub thawv hloov pauv. Pab pawg tu tsev cia siab rau SFRA txhawm rau txhawm rau nthuav tawm cov cua deformation, cov tub ntxhais- cuam tshuam tsis zoo, thiab qhib lossis luv luv- cov xwm txheej hauv Circuit Court- txhua yam tsis muaj nuj nqis thiab kev ua haujlwm cuam tshuam ntawm kev rhuav tshem lub cuab yeej.
Dab tsi yog cov yam ntxwv technical?
Cov yam ntxwv ntawm transformer windings yog ntsuas nrog zaus cheb txoj kev. Deformations ntawm windings xws li distortion, o los yog hloov chaw ntawm 66kV thiab saum toj no transformer yog ntsuas los ntawm kev kuaj amplitude - zaus teb cov yam ntxwv ntawm txhua winding, tsis tas yuav lifting transformer enclosure lossis disintegration.

FAQ
Q1: Cov txiaj ntsig kev xeem puas raug cuam tshuam los ntawm kev xeem coj? Yuav tshem tawm qhov kev cuam tshuam li cas?
A: The influence is indeed significant, particularly in the high-frequency range (>100 kHz). Lub inductance thiab capacitance ntawm kev xeem coj tuaj yeem tsim cov resonant circuits ntxiv nrog rau winding hauv kev sim.
Txoj kev tshem tawm:
Siv cov qauv kev xeem coj los ntawm cov chaw tsim khoom, kom ntseeg tau tias qhov sib xws ntawm qhov ntev thiab kev sib haum xeeb ntawm lub cev.
Thaum ua qhov kev ntsuam xyuas sib piv, xyuas kom meej tias cov txheej txheem txhuas tseem zoo ib yam ntawm cov kev xeem sib law liag.
Ua kom pom tseeb ntawm cov txheeb ze hloov pauv hauv qhov nkhaus (piv txwv li, peb- theem kev sib piv lossis kev sib piv keeb kwm) es tsis yog ntawm tus lej ntawm qhov tseem ceeb, vim tias qhov kev cuam tshuam ntawm kev xeem coj yog feem ntau hauv qhov xwm txheej.
Q2: Ntev npaum li cas SFRA xeem?
A: Piv nrog rau kev ntsuas qhov ntsuas hluav taws xob lossis ntsuas qhov ntsuas hluav taws xob, SFRA kuaj yuav siv sijhawm ntev dua. Kev ua tiav peb -theem xeem (xws li kev xaim, luam theej duab, thiab txuag cov ntaub ntawv) feem ntau xav tau 20 mus rau 40 feeb, nyob ntawm seb muaj pes tsawg tus scan ntsiab lus thiab qhov ntau zaus xaiv. Txawm li cas los xij, xav txog qhov muaj txiaj ntsig ntawm kev tshuaj ntsuam xyuas cov ntaub ntawv nws muab, qhov no yog cov txheej txheem ua tau zoo nyob rau hauv cov ntsiab lus ntawm kev tu transformer.
Q3: Vim li cas qhov ntsuas qhov nkhaus qee zaum tsis sib xws -featuring ntau spikes lossis "glitches"- dua li tsis du?
A: Qhov no feem ntau tshwm sim los ntawm ambient electromagnetic cuam tshuam lossis tsis zoo hauv av. Nyob rau hauv ib puag ncig substation, muaj zog electromagnetic teb tuaj yeem ua ob peb rau hauv qhov ntsuas ntsuas.
Cov kev daws teeb meem: Xyuas kom tseeb tias lub hauv paus rau ob qho tib si ntsuas ntsuas thiab cov cuab yeej hauv kev sim yog ruaj ntseg thiab txhim khu kev qha; siv cov kev xeem coj nrog kev tiv thaiv zoo tshaj plaws; pab kom qhov nruab nrab lim dej ua haujlwm hauv software; thiab, yog tias tsim nyog, tos rau qhov chaw cuam tshuam hauv cheeb tsam (xws li lub cev muaj zog loj tam sim no nyob rau hauv kev ua haujlwm) yuav tsum raug kaw ua ntej pib qhov kev xeem.
