摘要
在交流负载下,继电器的动作时间等时间参数的测量方法受到人们的关注,本文阐述一种利用计算机数据处理技术,对检测到的触点电压求取导数,计算交流电压峰值,通过峰值的变化判定触点状态进而计算继电器动作、释放等时间参数的原理与实现方法。该方法在自行设计的继电器电寿命试验设备中应用,效果良好。
Under the AC load, measuring methods for relay's time parameters like operating time has become more and more attracted. The paper expounds a data processing technique based on computer. It works out the AC voltage peak value, through the variety of the voltage peak and the contact derivative voltage, it determines the state of contact and calculates the time parameters such as parameters of operating and releasing time. This method has been used in relay electric life testing equipment with a satisfactory result.
