一种用于环网柜的wx型配电故障诊断自动化装置

Abstract

本发明涉及一种用于环网柜的WX型配电故障诊断自动化装置,该装置包括电源板、主控制板、电力载波板、3路电流互感器、3路电压互感器、6路遥信模块,所述的主控制板、电力载波板与电源板连接,所述的电力载波板、3路电流互感器、3路电压互感器、6路遥信模块均与主控制板连接。与现有技术相比,本发明实现对环网柜的故障信号的采集和遥信信号的监测并通过电力载波上传给调度,在环网柜母线停电后,本设备可以可靠的工作10分钟,将故障信号上传。
The invention relates to an automatic device for WX power distribution fault diagnosis of a ring main unit, which comprises a power board, a main control board, an electrical power carrier plate, a 3-way current transformer, a 3-way voltage transformer and a 6-way remote signaling module. The main control board and the electrical power carrier plate are connected with the power board, and the electrical power carrier plate, the 3-way current transformer, the 3-way voltage transformer and the 6-way remote signaling module are all connected with the main control board. Compared with the prior art, the automatic device collects the fault signals of the ring main unit, monitors the remotely signalized signals and uploads the signals to a dispatcher through the electrical power carrier plate. When the bus of the ring main unit is in power failure, the automatic device can reliably work for 10min to upload the fault signals.
