Abstract

The present application discloses a multifunctional power instrument which comprises a signal collection module which carries out signal collection on power equipment to be measured, an analog to digital conversion module which carries out analog to digital conversion on the signal collected by the signal collection module, a switch value input module used for generating a switch value, a communication circuit which generates a communication control signal, a signal processing module which is connected to the analog to digital conversion module, the switch value input module and the communication circuit and correspondingly carries out signal processing on the digital signal outputted by the analog to digital conversion module and the switch value outputted by the switch value input module under the control of the communication control signal generated by the communication circuit, and a segment LCD screen which displays the information obtained after the completion of the signal processing by signal processing module. According to the multifunctional power meter, integration degree of an instrument is improved, thus the wire arrangement between circuits is reduced, and the interference immunity of the instrument is improved. In addition, the information is displayed through the segment LCD screen, and thus the information effect of the multifunctional power instrument is improved.

Description

technical field [0001] The invention relates to the technical field of instrument development, in particular to a multifunctional power instrument. Background technique [0002] MFPM (MFPM, that is, MultiFunctionPowerMeter, multifunctional power meter) is an instrument that can measure three-phase electricity, such as three-phase voltage, three-phase current, active power, reactive power, apparent power, power factor and frequency. It can be widely used in the fields of substation automation, distribution automation, intelligent building, and enterprise internal power measurement. However, the multi-function power meters currently on the market have low internal integration and complicated circuit wiring, which also makes the multi-function power meters poor in anti-interference performance and has disadvantages such as poor information display effect. [0003] To sum up, it can be seen that how to improve the integration of multi-functional power meters, to improve the ant...
