Hom kev kuaj tawm ib nrab thiab qhov chaw tsim nyog

Tej zaum yuav muaj ib feem ntawm qhov hluav taws xob rwb thaiv tsev nruab nrab ntawm cov khoom siv hluav taws xob hauv cov khoom siv hluav taws xob tshiab los yog cov cables hauv kev ua haujlwm ntev.Txhawm rau txhawm rau txhawm rau txheeb xyuas cov insulation no tsis xws luag thiab tsis zoo sai li sai tau, kev tawm tsam ib nrab ntawm cov cabais tuaj yeem tiv thaiv thiab nrhiav cov teeb meem thiab txwv tsis pub poob rau lub sijhawm.zam kev poob ntxiv.

Hom kev kuaj tawm ib nrab thiab qhov chaw tsim nyog?
Nws yog tsuas yog siv rau ib feem ntawm kev kuaj pom ntawm high-voltage cables ntawm 110kV thiab saum toj no, siv cov cuab yeej los sau cov teeb liab los ntawm cable grounding box, thiab xaiv ntau hom kev xeem raws li qhov chaw ib puag ncig thiab kev xav tau, uas tuaj yeem faib ua 4 hom. :
① Tiv thaiv qhov ntsuas hluav taws xob ib nrab ntawm qhov tso tawm.Koom tes nrog cov high-voltage withstand voltage test khoom xws li zaus hloov dua siab tshiab los yog series resonance, thiab ua ib feem kev ntsuas paug thaum lub sij hawm ua tiav cable los yog niaj hnub xeem.
② Kev kuaj pom nyob.Siv ntsuas sensors xws li HFCT, siab-frequency capacitive arm, foil membrane electrode, thiab lwm yam.
③ Online PD saib xyuas.Cov cuab yeej kuaj pom tau raug teeb tsa rau ntawm qhov chaw sim rau lub sijhawm tiag tiag ntawm ib feem ntawm kev tso tawm teeb liab saib xyuas.
④ Kev kho mob hnyav.Cov cuab yeej tuaj yeem ntsia tau rau ntawm qhov chaw los saib xyuas cable PD tiam sis hauv online rau kev saib xyuas luv luv lossis mus sij hawm ntev.
