Automated Measure System Study of Creepage Distance and Clearance of Outlet

爬电距离与电气间隙是插座重要的安全检测参数,针对目前对其自动化检测程度不高的问题,研究开发了一套基于机器视觉的插座爬电距离与电气间隙自动化测量系统,提出了几何相似法将高度距离转化为平面距离。解决了高度计算不准,测量效率较低的问题。该系统采用图像处理的方法进行特征点提取并计算。通过对该系统的实际测试,结果表明该测试系统可以实现自动化快速测量,测量误差小于4%,满足国标要求。此系统可用于常见插座的爬电距离与电气间隙检测。

Creepage distance and clearance are the crucial safe testing parameters of outlet. Aiming at the problem of low de gree of automatic detection, a set of automatic measurement system based on machine vision is developed, which would promote ge ometry-similarity-calculation method to transform height range to plan range. The problem of high calculation inaccuracy and low ef ficiency is solved. The system uses image processing method to extract and calculate feature points. The results show that the test sys tem can realize automatic rapid measurement, and the en＇or is less than 4%, which meets the national standard. Therefore, this sys tem could be used in commun measuring of creepage distance and clearance of outlet.
