Dab tsi yog qhov ntsuas hluav taws xob siab ntawm transformer?
High-Kev ntsuas hluav taws xob ntawm cov khoom siv hluav taws xob yog qhov tseem ceeb ntawm kev ntsuas kev ntsuas hluav taws xob hauv kev lag luam hluav taws xob, siv los ntsuas qhov ntsuas hluav taws xob zoo, hluav taws xob muaj peev xwm tiv taus, thiab kev ua haujlwm tag nrho ntawm cov hluav taws xob hloov hluav taws xob thiab kev faib hluav taws xob. Cov kev ntsuam xyuas no tau ua raws li cov qauv thoob ntiaj teb xws li IEC thiab IEEE, thiab tau siv dav hauv kev tshuaj xyuas lub Hoobkas zoo, kev lees txais qhov kev xa khoom, ntawm - qhov chaw commissioning thiab debugging, thiab kev tiv thaiv ib ntus. Rau cov neeg yuav khoom, engineering integrators, thiab kev khiav hauj lwm thiab kev saib xyuas (O&M) cov koom haum, kev nkag siab meej ntawm kev faib tawm thiab cov txheej txheem tsim nyog tom qab siab -voltage transformer testing ua lub hauv paus tseem ceeb rau kev xaiv cov khoom siv, kev lees paub ua raws li txoj haujlwm, thiab kev tswj xyuas ntev - lub sijhawm ua haujlwm txaus ntshai.
Hauv kev siv engineering, high-voltage transformer test feem ntau yog muab faib ua peb pawg: AC tiv taus qhov ntsuas hluav taws xob, DC tiv thaiv qhov ntsuas hluav taws xob, thiab ntsuas qhov ntsuas hluav taws xob. Peb hom kev ntsuam xyuas no ntxiv rau ib leeg, ua kom tiav siab -voltage insulation testing system uas suav nrog kev txheeb xyuas qhov kev ua tau zoo ntawm rwb thaiv tsev nyob rau hauv ob qho tib si kev ua haujlwm ib txwm muaj thiab kev ua haujlwm hnyav. Ntawm cov no, AC tiv thaiv qhov ntsuas hluav taws xob simulates daim phiaj hluav taws xob ntawm 50/60 Hz fais fab zaus kev khiav hauj lwm voltage thiab luv luv - lub sij hawm overvoltage tej yam kev mob. Nws tshwj xeeb pom muaj qhov tsis xws luag-xws li cov dej nkag, tawg, thiab kev sib txuas tsis zoo- nyob rau hauv cov khoom tseem ceeb xws li transformer windings thiab bushings, ua rau nws yog qhov kev sim tseem ceeb rau kev ntsuam xyuas qhov kev ua haujlwm ntawm lub tshuab hluav taws xob.
DC tiv thaiv qhov ntsuas hluav taws xob sib txawv ntawm AC tiv thaiv qhov ntsuas hluav taws xob hauv lawv cov ntawv thov scenarios. Cov cuab yeej ntsuas no muaj kev siv hluav taws xob tsawg thiab yooj yim rau ntawm - qhov chaw xa tawm, thiab feem ntau yog siv rau kev ntsuas hluav taws xob ntawm cov khoom siv hluav taws xob thiab cov khoom siv. Txawm li cas los xij, txij li nws qhov hluav taws xob DC tsis tuaj yeem simulate qhov hloov pauv ntawm AC kev ua haujlwm tiag tiag, nws tsis tuaj yeem pom qhov cuam tshuam tsis zoo ntawm cov hluav taws xob tsis zoo hauv cov windings. Yog li ntawd, nws tsuas yog siv tau los ua ib qho kev ntsuas kev pabcuam thiab tsis tuaj yeem siv los ua lub hauv paus rau kev txiav txim siab tag nrho cov khoom siv. Nyob rau hauv sib piv, xob laim impulse thiab switching impulse tests siv ultra-siab-voltage pulses instantaneously los xyuas ib tug transformer lub peev xwm los tiv thaiv xob laim surges thiab daim phiaj switching overvoltages, npog heev heev scenarios kev khiav hauj lwm scenarios uas ib txwm tiv thaiv voltage xeem tsis tau simulate.
Hauv kev yuav khoom thiab ntawm -qhov chaw engineering applications, sib txawv - zaus AC resonant tiv taus qhov ntsuas hluav taws xob tau dhau los ua qhov kev lag luam tseem ceeb thiab kev daws teeb meem. Piv rau ib txwm muaj hwj chim- zaus tiv taus cov khoom siv hluav taws xob, AC resonant kuaj tshuab tsim cov khoom tso tawm ntshiab thiab ruaj khov nrog qhov raug siab voltage. Cov txheej txheem xeem tsis ua rau muaj kev puas tsuaj rau cov khoom siv hluav taws xob tsis zoo thiab ua tau raws li cov qauv ntsuas kev ntsuas rau kev kuaj lub Hoobkas, kuaj kev lees paub ntawm lub Hoobkas (FAT), thiab ntawm - qhov chaw lees txais, ua rau lawv tsim nyog rau kev sim transformers ntawm txhua theem voltage.
Kev ntsuas siab siab- qhov ntsuas hluav taws xob tuaj yeem txheeb xyuas qhov muaj peev xwm hloov hluav taws xob rwb thaiv tsev ua ntej, tiv thaiv kev nyab xeeb zoo li kev cuam tshuam kev rwb thaiv tsev, kev ua txhaum ntawm cov khoom siv, thiab cov khoom siv hluav taws xob tom qab muab tso rau hauv kev ua haujlwm. Nws yog txoj hauv kev sim ntsuas qhov tseem ceeb rau kev txiav txim siab qhov zoo ntawm cov khoom siv hluav taws xob thiab ua kom lub sijhawm ntev - ua raws thiab kev ua haujlwm ruaj khov ntawm daim phiaj hluav taws xob, nrog rau cov txheej txheem tseem ceeb rau kev xaiv cov khoom siv thiab kev lees paub hauv kev lag luam.
