摘要

为研究导线表面电场强度对导线覆冰的影响

在魁北克大学希库蒂米分校电网设备大气覆冰试验室（INGIVRE）的人工气候室内通过电晕笼进行导线带电覆冰试验。试验结果表明导线表面电场强度对导线覆冰质量、形状、冰凌间距、电晕损失以及泄漏电导和导线电容等产生影响。电场强度的增加使雾凇表面产生水膜、雨凇冰凌长度减少。当导线表面电场强度≤20 kV/cm时

导线表面覆冰质量随电场强度的增加而增加。电场强度进一步增加时

导线表面覆冰质量减少。当被导线捕获的水滴在重力作用下流到导线下表面后立即被冻结时

冰凌间距和场强无关。当降雨量较大时

冰凌间距随着场强的增加而减少。导线在雾凇和雨凇覆冰时

电晕损失和由电晕产生的电导随场强的增加而增加。雨凇覆冰时

由于冰凌长度的影响

导线表面电场强度为5 kV/cm时导线的单位长度电容反而比电场强度为25 kV/cm时大。

Abstract

To investigate the influences of electric field of conductors surface on conductor icing

experiments were carried out in a climate room based on corona cage at INGIVRE laboratories

University of Quebec in Chicoutimi（UQAC）. The experimental results show that the electric field has significant influences on ice weight and appearance

icicle spacing

corona loss

leakage conductance

and capacitance. With the increase of electric field

water film could be observed on the conductor surface under rime accretion and the length of icicles decreases under glaze ice accretion. Under both rime and glaze ice conditions

the weight of ice accreted increases with electric field strength up to 20 k V/cm and then decreases as it increases further. When the precipitation rate is low

and the water film is frozen immediately when it reaches the bottom of the conductor due to gravity

the icicle spacing is independent of the conductor surface electric field. When the precipitation rate is sufficient

icicle spacing decreases as the electric field at the surface of the conductor increases. For both rime and glaze ice accretion

the corona loss and the leakage conductance induced by corona discharge increase with an increase of electric field. Under glaze ice condition

due to longer icicles

the capacitance per unit length is higher when the electric field is 5 k V/cm compared with that of 25 k V/cm.
