摘要
现有输电线路验电技术大多采用接触式,用于特高压线路时存在操作不便及一定的安全隐患。该文介绍的一种非接触式线路验电装置,基于垂直场强差分布曲线匹配方法,通过对垂直于地面、垂直于输电线路走向的电场强度分量的测量,将其与仿真计算得到的标准数据进行比对分析得到输电线路的带电状态。实现了在塔下非接触式安全验电,确保了作业人员的安全。经多条特高压线路实测,采用这种算法的验电装置验电准确、安全便捷。为特高压输电线路验电提供了一种安全有效的新方法。
Most of existing transmission line chargedcheck technology uses the contact, when used in UHV line is inconvenient operation and certain security risks. This paper introduces a kind of non--contact line charged check device, based on the vertical electric field intensity distribution curve matching method, based on the perpendicular to the ground, perpendicular to the electric field component of the transmission lines to measurements, with the standard data obtained by the simulation calculation comparison analysis get charged slate of the transmission line. Realize non--contact safety inspection under the tower, ensure the safety of workers. By multiple UHV line measurement, the device using thisalgorithm inspection accurate, safe and convenient. The device provides a safe and effective new method for UHV transmission lines inspection.
