电器产品的工作电压测试与分析

Testing and Analysis of the Operating Voltage Electrical Products

工作电压是用来确定被测样品电气强度试验电压、爬电距离和电气间隙限值的重要依据。该文较为详细地介绍了电子电器产品工作电压的确定及测量要求,以某一隔离变压器为例进行实测说明,总结了工作电压测试中测量设备、接地、隔离、初次级共电位等因素对测试结果的影响,最后说明如何根据工作电压来确定被测样品的爬电距离和电气间隙。

The sample is determined creepage distances, electric gap and dielectric strength based on the operating voltage. This article gives a detailed introduction of the determination and measurement requirements of electrical and electronic products operating voltage, a typical example for the actual sample instructions,summarized the work of measuring voltage test equipment, grounding, isolation, primary and secondary cofactors such as the potential of the test results influence, and finally explain how the sample to determine the creepage distance and electric gap according to operating voltage.
