工频电场对ADSS光缆特性的影响

随着电压等级的不断提高,超高压输电线路发展非常迅速.但是这些架空输电线路在运行时,附近存在较高的电场,对周围物体和公用走廊的其它线路会产生影响.电压等级越高,产生的电场影响越大.输电线路产生的电场越来越受到人们的重视.尤其是对于超高压输电线路,由于在电力铁塔上同塔悬挂全介质自承式光缆(ADSS),因此分析工频电场对ADSS光缆特性的影响非常必要.

The effect of electric field on ADSS characteristics

With the increasing level of power line voltage, the high voltage power line is developing very fast. When this power line is active, there is electric field around with them which would cause electro-magnetic interference. The higher the voltage level of the power line is, the worse of the electro-magnetic interference effect is. For the safety of the human being and the equipments, we must pay attention to the electric field caused by the higher voltage level of the power line, especially for the ultra high voltage of the power line. We must analyze the distributing electric field of power line iron tower when ADSS cable spanning with the high voltage power line.
