高低压配电柜母线温度及电流综合监控装置设计及实现

Design and implementation of comprehensive monitoring device for bus temperature and current of high andlow voltage distribution cabinet

高低压配电柜是供配电系统中的常见装置,其母线的温度及电流监控是构建配电站智能化体系的重要基础。为此,文章以功能需求为研究起点,对监控装置的总体设计进行明确,并按照温度监控、电流监控两部分对具体模块进行设计与实现。结果表明:该系统能够实现对配电柜运行状态的监控,也能够对可能存在的异常情况进行警报,扩展维修维护的时间窗口,保障配电柜的平稳运行。

The high and low voltage distribution cabinet is a common device in the power supply and distribution system.The temperature and current monitoring of the bus is an important basis for constructing the intelligent system of the distribution station.Therefore,this paper starts from the functional requirements,makes the overall design of the monitoring device clear,and designs and implements the specific modules according to the two parts of temperature monitoring and current monitoring.The results show that the system can monitor the running state of the distribution cabinet.It can also alert possible abnormal situations,expand the time window for maintenance,and ensure the smooth operation of the distribution cabinet.
