摘要
为保证高压输电线路接地引下线满足线路安全运行的需要,需要对接地引下线完整性进行检测。本文通过采用管线仪探测法对高压输电线路塔基接地引下线的走向、位置和埋深进行探测,快速准确地得出接地引下线的平面走向、位置和深度,进而分析得出其完整性,并通过局部开挖验证了探测结果的正确性和准确性。实践结果表明,管线仪探测法能够克服各种不利条件,具有方便、快捷、准确的特点,在输电线路的安全运行及维护上具有重大安全意义。
In order to ensure the down leads of transmission line safe operation,it is need to check the integrity of the down leads.The paper mainly studied the pipeline locator detection method,and use it to detect the direction,location and depth of down leads in high voltage transmission line.Through this method can quickly and accurately obtain the plane direction,position and depth of down lead,then draw its integrity.The correctness of the detection results are verified by local excavation.It shows that the pipeline locator detection method can overcome the adverse conditions,and have the characteristics of convenient,quick and accurate.This method has a great security significance on the safe operation and maintenance of the transmission line.
