Kev ua haujlwm ntawm cov khoom siv insulators

Composite insulators yog tshwj xeeb insulating Cheebtsam siv nyob rau hauv overhead kis kab. Lawv lub luag haujlwm tseem ceeb suav nrog nce qhov kev ncua deb (feem ntau 300-500mm), txhawb nqa cov neeg siv khoom, thiab tiv thaiv tam sim no rov qab los rau hauv av. Lawv cov qauv muaj cov ntaub ntawv insulating (xws li silicone roj hmab) thiab cov tub ntxhais hlau, uas muaj kev tsim kho lub teeb (50% -70% sib dua li ceramic insulators), lub zog tensile siab (Ntau dua lossis sib npaug rau 120kN), thiab kev ua qias tuaj zoo heev (hydrophobicity HC1-HC3 qib). Lawv tsim nyog rau qhov chaw hnyav xws li substations thiab ntug hiav txwv dej uas muaj ntsev ntau.

Lawv lub luag haujlwm tseem ceeb yog tshwm sim hauv peb yam:

1. Txhim kho kev ruaj ntseg, muaj peev xwm tiv taus huab cua huab cua nrog cua nrawm txog 40m / s, thiab kev ua haujlwm siab ntev txog 160kN;

2. Txo cov nqi tu, nrog lub neej ntev txog li 30 xyoo, thiab tus kheej- cov khoom siv tu kom txo tau cov zaus ntxuav ntau dua 90%;
3. Txhim kho kev nyab xeeb, nrog kev taug qab tsis kam mus txog qib TMA4.5, thiab ntub dej flashover voltage 20% -30% siab dua li cov porcelain insulators.
