XP-dog dig tshem tawm cov plooj (insulator) tsis tuaj yeem hais los ntawm electromechanical kev puas tsuaj; X- dog dig raug tshem tawm plooj hlau insulator qhia los ntawm electromechanical load rau ib teev, tus lej nyob rau hauv kaum sab xis yog tus tsim cov lej ua ntu zus, tus lej 70, 80, 100, 120, 160, 210, 300 yog ntsuas qhov electromechanical rhuav tshem (KN) ; 3, 4,5 yog cov khoom siv kho tshuab (t) rau kev sim electromechanical ib teev, C-zawj txuas (qhov txuas txuas tsis muaj qhia). Cov pa phem tsis kam ntawm cov rwb thaiv tsev yog nyob ntawm tus qauv ntawm cov khoom thiab cov duab ntawm lub kaus tiab. Ntau qhov haujlwm tau ua tiav hauv qhov no. Los ntawm kev tsim cov kev ua kom zoo, kev ua kom cov pa phem ntawm cov tshuaj ntsuam kom zoo dua qub thiab cov pa phem ntsuas kev ua kom zoo dua, cov insulator tiab nrog cov tsaj loj thiab me me thiab cov hlua khawm kom pom tau txiav txim siab. Cov rwb thaiv tsev nrog qhov ntsuas hluav taws xob ntawm 126kV thiab 252kV thiab lub khoov tsis ua haujlwm thauj khoom ntawm tsis qis dua 12kV thiab qhov nkag ntawm qhov nruab nrab nrug ntawm 25 hli / kV tsim nrog lub tiab no tuaj yeem tiv taus kev ua haujlwm theem voltages rau lub sijhawm ntev raws li 0.12mg / equivalent2 sib npaug ntsev ceev, namely chav kawm III nkag nthwv dej deb ntawm lub rwb thaiv tsev yog thev taus ntawm chav kawm IV sib npaug ntsev-nruj cov pa phem. Cov ntxig hluav taws xob nrog qhov ntsuas hluav taws xob ntawm 550kV thiab qhov nkag ntawm qhov nruab nrab ncua deb ntawm 25mm / kV tuaj yeem ua haujlwm rau lub sijhawm ntev ntev raws li 0.06mg / equivalent2 sib xyaw ntsev kom tsawg. Kev ua qias tuaj yeem tiv thaiv theem ntawm cov rwb thaiv tsev yog qhov zoo tshaj plaws nyob rau hauv Suav teb, thiab nws tuaj yeem tiv taus qhov sib npaug ntsev kom muaj nuj nqis ib feem peb siab dua li ntawm cov khoom sib xws nrog cov nkag ntawm qhov sib npaug thiab sib npaug diam tiab tiab. Cov txiaj ntsig ntawm kev ua kom muaj kuab paug tsis zoo rau kev ntsuas hluav taws xob ntawm lub rwb thaiv tsev ntawm Northeast Hluav Taws Xob Hluav Taws Xob thiab Kev Tshawb Fawb Kev Tshawb Fawb tau qhia tias qhov ntsuas hluav taws xob nrog qhov sib npaug ntawm qhov sib npaug ntawm 31 hli / kV tiv taus tus nqi siab ntsev ntawm 0.25 mg / ㎝2.
Muaj av qeeg ua hauj.
Cov kab hluav taws xob nrog cov ntsuas hluav taws xob ntsuas ntawm 252kV thiab 550kV tau sim rau seismic kev ua tau zoo ntawm qhov ua tau zoo 9 ntawm Beijing Institute ntawm Cov Khoom Siv Hauv Dej thiab Kev Tshawb Fawb, thiab cov txiaj ntsig tsis zoo.
Muaj xov tooj cua tsawg cuam tshuam.
Cov kab hluav taws xob nrog qhov ntsuas hluav taws xob ntawm 550kV tsim cov xov tooj cua cuam tshuam ntawm tsis ntau tshaj 500μV ntawm 1.1 lub sijhawm ua haujlwm theem voltage. Tsis muaj qhov pom ntawm corona nyob rau hmo ntuj tsaus ntuj, thiab qhov pom hluav taws xob qhov hluav taws xob qhov hluav taws xob tsis muaj ntau npaum li 450kV.
