1. Taw qhia
Hauv kev lag luam thoob ntiaj teb, txawv teb chaws EPC tej yaam num thiab daim phiaj daim ntawv pov thawj rau33kV roj immersed transformers, Hom Kev Ntsuas thiab Kev Ntsuas Kev Ntsuas yog ob qhov tseem ceeb tshaj plaws thiab feem ntau tsis meej pem kev sim ntsuas raws li IEC 60076 tus qauv. Ntau tus neeg yuav khoom txawv teb chaws, tus thawj saib xyuas qhov project thiab cov kws ua haujlwm hauv teb ua yuam kev ntseeg tias cov kev sim niaj hnub hauv lub Hoobkas tuaj yeem hloov cov kev xeem, ua rau tsis tsim nyog rau kev sib tw, daim phiaj sib txuas tsis ua haujlwm thiab cov khoom siv tsis raug.
Raws li cov lus txhais ntawm IEC, kev sim ntsuas hluav taws xob tau muab faib ua peb pawg: Hom Kev Ntsuas, Kev Ntsuas Kev Ntsuas thiab Kev Ntsuas Tshwj Xeeb. Hom Kev Ntsuas xyuas tag nrho cov qauv tsim tsim nyog, rwb thaiv tsev robustness, thermal stability thiab luv luv -circuit withstand peev xwm. Cov Kev Ntsuas niaj hnub raug ua nyob rau hauv txhua chav tsev kom tshem tawm cov khoom tsis xws luag. Kab lus no qhia meej meejHom Kev Ntsuas thiab Kev Ntsuas Cov Khoom Ua Si rau 33kV roj transformers, pab cov pab pawg thoob ntiaj teb ua tau raws li kev ua raws cai thiab kev lees txais kev tshaj lij.
2. Qhov sib txawv ntawm qhov tseem ceeb ntawm hom kev xeem thiab kev xeem niaj hnub
Ib Hom Kev Xeem yog ib qho - lub sij hawm tso cai tsim qauv kev kuaj xyuas ua tiav ntawm cov qauv hloov pauv ntawm tib tus qauv thiab cov qauv. Ntev npaum li tus qauv tsim, cov ntaub ntawv thiab cov qauv tseem tsis hloov pauv, daim ntawv tshaj tawm hom kev xeem yuav siv tau mus tas li. Nws yog ib qho tsim nyog yuav tsum tau tsim nyog rau kev sib tw thoob ntiaj teb kev sib tw, tsoomfwv cov haujlwm thiab cov ntawv cog lus loj - EPC, ua pov thawj tias tus qauv tsim hluav taws xob tuaj yeem tiv taus kev ua haujlwm hnyav.
Kev Xeem Routine yog 100% yuav tsum tau kuaj lub Hoobkas rau txhua tus neeg hloov pauv. Nws tsom rau kev tsim tshuaj xyuas zoo, tshem tawm cov teeb meem zais xws li rwb thaiv tsev dampness, winding yuam kev, sib dhos deviations thiab sealing tsis xws luag. Cov kev ntsuam xyuas niaj hnub ua pov thawj qhov zoo ntawm txhua chav ua tiav tab sis tsis tuaj yeem hloov hom kev xeem rau kev tsim ntawv pov thawj tsim nyog.
Nyob rau hauv luv luv, hom kev ntsuam xyuas tsim nyog tus tsim, thaum cov kev ntsuam xyuas niaj hnub tsim nyog ib tug neeg cov khoom units. Ob leeg yog qhov tseem ceeb rau kev ua raws li IEC 60076 tag nrho.
