摘　　要：爬电距离和电气间隙是电子产品中一项重要的安全检测项目。爬电距离是沿绝缘表面测得的两个导电零部件之间的最短路径,电气间隙是在两个导电零部件之间测得的最短空间距离。在平时测试时,爬电距离与电气间隙的确定通常是在同一个平面内完成的,重点阐述了涉及到不同平面之间的空间爬电距离和电气间隙的测量,结合具体图形的分析,说明了测量时应注意的事项。Electrical creepage distance and clearance is an important electronic product safety testing program. Creepage distance is measured along the insulating surface between the two conductive parts of the shortest path, the electrical gap between two conductive parts in the shortest measured distance. In the usual tests, electrical creepage distance and clearance determination is usually done in the same plane, this article focuses on the different planes involved in the space between the electrical creepage distance and clearance measurements, combined with the analysis of the specific graphics shows the measurement points to note.
