智能水表环境影响量试验的原理和方法

The Principle and Method of Environment Influence Tes on Smart Water Meter

环境影响量试验是电子水表和带电子装置水表型式试验和型式评价的重要组成部分。介绍了影响量试验(即环境试验)的条件和严酷度等概念,对机械环境中的振动和冲击试验、电磁环境中的静电放电试验、电磁敏感性试验、浪涌抗扰度和电脉冲群等试验的原理和方法作了较为详细地分析和描述。

Environment influence test is the important part of the pattern evaluation and pattern test for electronic water meter and the mechanical water meter with electronic device. This paper introduces theeoneept of test condition and severe degreeofinfluence quantity.And it analyzes and describes the vibration and impact test of the mechanical envi- ronment, the electrostatic discharge test of electromagnetic environment, the electromagnetic susceptibility test, thesurge immunity and electrical group test, etc.
