Abstract

The invention discloses an intelligent electric meter capable of identifying a vicious load. The intelligent electric meter comprises an input circuit, the single-phase or three-phase electric meter, a relay and an output circuit which are sequentially connected, wherein the single-phase or three-phase electric meter is internally provided with a vicious load identification unit, an output end of the vicious load identification unit is connected with an MCU core control circuit, an output end of the MCU core control circuit is connected with the relay through a control circuit, and the MCU core control circuit is supplied with power through a power source management circuit. According to the intelligent electric meter, the intelligent electric meter not only has a metering function of a routine meter, electricity can be timely monitored, normal electricity is not limited at all, for an abnormal electricity or the vicious load, the control circuit can be automatically started, and the output relay is disconnected; or through remote control, the control circuit is manually started, and the relay is disconnected; a purpose of identifying the vicious load to reduce electricity waste to realize electricity saving can be realized.

Description

technical field [0001] The invention relates to an intelligent electric energy meter capable of identifying vicious loads. Background technique [0002] The current power consumption load is relatively large. In the process of power consumption in public places, some users will use some household appliances or vicious loads with large power consumption without permission, exceeding the restricted use range. The sharp increase in power consumption will affect the overall power supply load and seriously reduce the quality of power supply. In order to overcome this defect, we have designed a vicious load system for identifying the total power consumption and instantaneous step power. Smart energy meter. Contents of the invention [0003] The object of the present invention is to provide an intelligent electric energy meter capable of identifying vicious loads in view of the defects in the prior art. [0004] In order to achieve the above object, the present invention adopts...
