山区高压输电铁塔边坡滑坡对超高压输电存在隐患,目前对边坡上的塔基进行长期监测并成功预警的案例很少。针对此,以广东电网有限责任公司韶关供电局指定的500 kV 坪曲线163号塔为研究对象,介绍一种由大量程位移计组成的自动化安全预警系统在山区输电塔基边坡位移监测的应用。实际应用结果表明,其测量精度可达0.01 mm,通过移动网络通用分组无线服务技术可以进行远程数据采集、数据传输、测量控制,全程自动化,有效降低了长期监测成本。

Landslide of side slope of high voltage power transmission tower in mountainous area may cause hidden danger to extra-high voltage power transmission and there are few cases of long-term monitoring and successful prewarning on tower footing on the side slope at present. Therefore,application of a kind of automation security prewarning system constituted of wide-range displacement meter in monitoring on side slope displacement of power transmission tower footing in mountain-ous area was introduced by taking No.63 tower of 500 kV Pingqu line appointed by Shaoguan power supply bureau for an ex-ample. Practical application result indicates that measuring precision of the system could be 0.01 mm and by means of gener-al packet radio service(GPS)technology,it is able to realize remote data acquisition,data transmission and measurement control. Meanwhile,full-process automation is effective to reduce long-term monitoring cost.
