电能表印刷电路板耐雷电冲击电压参数测定

Determining the lightning surge voltage-withstanding parameters of a printed circuit board designed for multimeters

对印刷电路板上线路间绝缘强度与线路间距关系进行了实验测定,给出了参考计算式,可作为仪表厂家设计计量仪表内部电路时的一个参考。

This paper deals with the experimental test of the relationship between the insulating strength and the line space on a printed circuit board. A reference formula is provided for determing it, which can serve as reference data for designing any muhimeters.
