直流系统端子型智能漏电监测

DC system leakage monitoring

采用以直流接地在线监测端子为主构架的分布式直流监测系统,它以端子的形式按装在端子排上,装置既可单独报警使用,又可联机通信。对其中的磁调制传感器进行改良,采用了单磁芯单绕组的磁调制直流漏电采样。它能在检测到漏电流后,进行故障判断,当确定为故障状态时能及时发出报警信号。设计采用的是Philips公司的P89LPC938FDH单片机。

Using a DC ground terminal-based online monitoring framework distributed DC monitoring system, which is installed in the form of terminal terminals block,and there is an alarm device can be used alone or by on-line communications.On which the magnetic modulation sensors improved,using a magnetic modulation DC single core single winding leakage sampling.It can detect the leakage current and determine the failures, when identifying the fault status, it can send out alarm signals in time. The design uses a Philips company P89LPC938FDH microcontroller.
