一种耐高压FBG压力传感器在电力铁塔塔基的应用
|
摘要
云南属低纬度高原及其向南倾斜的斜坡地区,地质条件与气候环境复杂,地质灾害繁多,这致使大多数山区电力铁塔塔基存在地质结构安全问题,严重威胁电力系统的稳定运行。为应对各种威胁铁塔安全的突发情况,设计一种耐高压的FBG压力传感器,实现对山区电力铁塔塔基土压力的实时监测预警,为变电站结构的安全维护工作提供辅助决策依据与技术支持。该传感器技术已经成功应用于云南省玉溪市山区某个220k V变电站。
Yunnan province is a low latitude plateau and sloped south area with complex climate and geological conditions, it is prone to suffer more earthquakes or other natural geological disasters, which resulted in the most of power tower located in mountainous region always face the security problems of geological structure, which is a serious threat to the stable operation of power system. In order to deal with various emergency situations of threatening the safety of the tower, a high-pressure-resistance FBG pressure sensor is designed to achieve the real-time monitoring and warning of the power tower earth pressure in mountainous region, and it also can provide auxiliary decision basis and technical support for the safety maintenance of the substation structure. The sensor technology has been successfully applied in a 220 k V substation in mountainous region of Yuxi city, Yunnan province.
