摘要

高电压设备外绝缘爬电距离是一项保证电网安全运行的重要参数。目前爬电距离测量工作均在设备停电情况下进行

需人工测量

测量数据误差大

数据核查周期长

不能满足电网设备管理要求。文中使用三维激光扫描技术对外绝缘爬电距离进行了带电检测

可获得准确的测量数据

创新了爬电距离带电检测方法

该新技术可以推广应用。

Abstract

The external insulation creepage distance of high voltage apparatus is an important parameter for the safety operation of power system.Creepage distance measurement is usually made by manual with a large error while apparatus is powered off

it will cost a lot of time

and cannot meet the need of apparatus management.In this paper

a new method for on-line measurement is presented with an accurate result

which is based on 3D laser scanning technology.Experiment shows that this new method is feasible and can be applied.
