给出了悬挂式无间隙氧化锌避雷器(MOA)相对座式的优点,计算了悬挂在变电站门型构架上MOA的电压分布情况,设计了均压环的最佳尺寸,并反映了悬挂式MOA离地高度对其电压分布的影响.

The method of rime formation in laboratory and artificial rime discharge tests of long insulator string were described. The test results confirm that there is a great difference of discharge phenomenon and electric insulation strength between the rime covered insulator and the glass covered one.
