Online phase-checking and electricity-testing monitoring device

The invention relates to an on-line nuclear phase electricity testing monitoring device which is characterized by comprising a plurality of monitoring sub-devices, and each monitoring sub-device comprises an MCU, an AD analog-to-digital converter, a communication module, a display screen and a key module. A host device is allocated to each monitoring sub-device, the rest are slave devices, the switch cabinet is connected, three-phase data of each line side of the switch cabinet are acquired, the acquired three-phase data are calculated, analyzed and displayed on line in real time, and the monitoring sub-devices are electrically connected with the MCU. Therefore, on-line phase-checking and electricity-testing real-time monitoring is carried out on the switch cabinet, timeliness of phase-checking monitoring is ensured, and operation is simple and safe. 本发明涉及一种在线核相验电监测装置，其特征在于：包括若干个监测子装置，各个监测子装置均包括MCU、AD模数转换器、通讯模块、显示屏和按键模块，AD模数转换器、通讯模块、显示屏、按键模块均与MUC电性连接通过将各个监测子装置分配出一个主机设备、其余为从机设备，通过连接开关柜，采集开关柜各线侧的三相数据，对采集到的三相数据进
