【摘要】 遭雷击的、运行中的及新的 3种 5 0 0kV线路悬式绝缘子在昆明 1970m海拔高度的试验室内的有限数量的工频和雷电冲击试验表明 ,不同绝缘状况下的绝缘子的电气特性不尽相同 ;同一杆塔上遭雷击的同一绝缘子串中各绝缘子的绝缘特性并不一样 ;与运行中的及新的绝缘子相比 ,遭雷击的绝缘子表面绝缘特性也不完全劣化。更多还原

【Abstract】 The test is made in laboratory in Kunming where the altitude is 1 970 m for comparison of electric performance of three different insulators. The three different 500 kV suspended insulators are respectively new, in operation and stroke by lightning. The test results show that the electric characteristic is different for insulators with different insulation condition.更多还原
