The three-phase four-wire system electric energy meter fault simulation device includes a fault type selection button module, an upper computer control monitoring module, a lower computer control processing module, a relay array module and a three-phase four-wire system electric energy meter, the simulation of voltage and current faults of the three-phase four-wire system electric energy meter is realized through the fault type selection button module or the upper computer control monitoring module, complicated wiring is not needed, the device is safe and reliable, and the operability is high; and the device not only realizes remote operation of fault simulation, but can also realize remote monitoring, thereby further improving safety and operability.

Description

technical field [0001] The invention belongs to the technical field of power metering fault simulation, in particular to a fault simulation device for a three-phase four-wire electric energy meter. Background technique [0002] With the determination of the national grid's smart grid development plan, smart meters, as the smart terminal of the smart grid, have broad market demand. Smart meters not only have the power metering function of ordinary meters, but also have the functions of real-time monitoring of power grid operation status and detection of fault types in external three-phase wiring. However, as smart energy meters enter the market, users have doubts about the reliability of smart meters, so it is necessary to calibrate the smart meters to check whether the energy meters can work safely and reliably. [0003] For metering personnel, it is necessary to master various types of faults in the three-phase four-wire system wiring before formal work, so that they can c...
