摘要
设计了一种具有电能质量监测功能的智能开关设备.该智能开关设备不仅具有微机保护功能,还具有波形畸变率、三相不平衡、电压波动、电压跌落等电能质量参数监测功能,是一种将电能质量监测和开关设备结合起来而组成的智能开关设备.介绍了设计方案和具体实现方法,着重阐述了硬件系统的原理和具体电路,解决了当线路发生短路故障而失压时的工作电源能量获取问题,并对软件设计要点进行了介绍.
A new type of intelligent switch device with the function of monitoring the power quality is designed.The device not only has the function of conventional circuit protection,but also can monitor a series of parameters such as the waveform distortion,voltage fluctuation,voltage drop and so on.This new intelligent switch device is composed of the electrical energy quality monitoring facilities and the switch component.In this paper,it introduces the design scheme of intelligent switch device and its detailed implementation method.It elaborates the principle of the hardware system and the concrete electric circuit.The paper also solves the core components＇ problem of getting the power supply when short-circuit fault happenes and leads to under-voltage.A brief introduction is given to the main points of the software design.
