光纤复合相线的电气性能研究与试验方法探讨

OPPC光缆是光缆和导线的复合体,在电力网络中起到通信和电能传输的双重功能,在110 kV及以下电压等级的输配电网络中有着广阔的应用前景。文章设计并实施了OPPC光缆电气性能试验（包括耐压性能试验和载流性能试验）,检测了试验过程中OPPC光缆的光纤传输损耗及光缆表面温度的变化趋势,对OPPC光缆的电气性能及部分光缆表面温升过高的应对措施进行了研究和分析,为OPPC的实际应用和入网检测试验方法提供了有意义的参考。

Electric property research and test methods discussion of OPPC

OPPC is a compound of optical cable and transmission line.It plays the role of both communication and power transmission in the power system,and has good application prospect in the 110 kV and below 110 kV power transmission and distribution networks of our country.This thesis designed and implemented OPPC cable′s electric tests,which include voltage withstanding test and current-carrying capacity test.The fiber attenuation and OPPC cable′s surface temperature were monitored during the tests.What′ s more,this paper analyzed OPPC cable′ s electric property and proposed some advice to solve problems of few OPPC cables,of which the surface temperature was too high in the current-carrying capacity test.This paper provided a meaningful reference to OPPC cable′s practical use and its network access test methods in the power system.
