摘要
在电器产品的安全设计过程中,确定并测量爬电距离和电气间隙的"最短"路径,是产品合格评定的重点和难点。本文分析了复杂路径情况下是否需要桥接,以及具体桥接方案的选取问题。本文通过产品模型举例介绍了从三维建模寻找、模拟最短路径,数学建模计算最短路径,再通过EXCEL或编程的方式利用计算机辅助计算获得最终爬电距离和电气间隙最短路径及数值的测量解决方案。该解决方案可以适用于其他复杂路径的爬电距离和电气间隙路径测量中。
In the safety design process of electrical products,determining and measuring the“shortest”path of creepage distance and electrical clearance is the focus and difficulty of product conformity assessment.This article analyzes whether bridging is necessary in the case of complex paths,and the selection of specific bridging schemes.This article uses product models to give examples of finding and simulating the shortest path from three-dimensional modeling,mathematical modeling to calculate the shortest path,and then using computer-aided calculations through excel or programming to obtain the final creepage distance and the shortest path of electrical clearance and numerical measurement solutions Program.This solution can be applied to the creepage distance and clearance path measurement of other complex paths.
