低电压开关设备的电压特性分析和测试系统的设计-----外文翻译.doc

Abstract - The test of low-voltage switchgear (contactor,relay, breaker etc.) includes electric longevity and electriccharacters of turn on-off. The fast calculation and analysis methods for electric parameters were investigated. Muchattention has been paid to the effect of performance in lowvoltage switchgear caused by arcing time, over-voltage of contact, power factor and harmonic. On the base of studyingcharacter of test, such as more measured signals, severity of disturbance from strong electromagnetism, shorter interval and vast data in test, an efficient testing system has been designed with the function of data acquisition and processing. This system possesses six channels of voltage signal and three channels of current signal. The frequency of data collecting in every channel is 1MS/s and the isolation voltage exceeds 2500V. The results show that all requirements in test have been implemented

摘要 - 低电压开关设备的测试 (电流接触器，继电器, 断路器等)旋转开关包括的使用寿命和电路特性。 电路参数的快速计算和分析方法的选取。应该更多注意对由燃弧时间引起的低电压开关设备中的性能效果,连接线路通过的高电压,激励因数和谐波。在了解测试特性的基础上,例如在测试中的比较多的测量信号, 来自强大电磁的强烈干扰，比较短间隔和大量的数据, 设计一个有效的测试系统用来进行数据获取和处理。 这个系统包括六个电压信号通道和三个电流通道。在每个通道中数据收集的频率是 1MS/ s ，绝缘电压超过 2500V 。结果要求测试中的所有需求都要全部实现。
