高压线路防外力破坏激光监测预警系统的研究

Study on Laser Monitoring and Early-warning System of High Voltage Line against External Damage

针对当前我国高压电力线路防外力破坏面临的严峻形势,设计出一种基于激光监测技术的输电线路防外力破坏监测预警系统,利用激光监测高压线路可能将要发生的外力破坏隐患,提前实现预报警和现场对讲警示阻止外力破坏的发生。该系统能够自动计算外物体接近高压线的位置距离,根据不同电压等级线路设定的安全距离参数来确定其危险程度,实现分档报警。通过实际应用论证了系统的正确性和可行性,对高压线路防外力破坏有着重要的指导意义。

In view of the severe situation of high voltage transmission line against external damage, the laser monitoring and early-warning system is designed. Destruction hidden trouble using laser monitoring high-volt- age lines could occur external force, advance warning and site intercom alarm prevent external damage. This system can be used to count the distance between objects and high voltage lines, automatically and determine danger on the basis of the safety distance parameters which are set by different voltage levels, realization sub file to alarm. Through the practical application proves the correctness and feasibility of the system, guiding significance to transmission line against externaI damage.
