Abstract

The invention discloses a verification training device for an electric energy metering device. The verification training device comprises a signal source module, an electric energy meter tail box anda reference port, the signal source module is used for outputting a phase voltage; the electric energy meter tail box is connected with the signal source module through a detachable wire, and is usedfor adjusting the phase sequence type of the phase voltage output to the electric energy metering device through the detachable wire; the reference port is connected with the signal source module andused for determining the phase sequence type of the phase voltage output to the detachable wire by the signal source module, and the technical problem that the signal source module is large in size and inconvenient to carry is solved.

Description

technical field [0001] The present application relates to the technical field of electric energy metering, in particular to a calibration training device for electric energy metering devices. Background technique [0002] Existing electric energy metering devices usually need to be calibrated before leaving the factory to ensure their accuracy. The verification of electric energy metering devices is usually that the electric energy metering personnel connect phase voltages with wrong phase sequence to the electric energy metering In the wrong state of phase voltage and phase sequence, the wrong electrical signal is connected, and then the voltage, current, power factor, frequency and other parameters are measured and verified. The electric energy metering personnel need to calibrate the electric energy metering device before going to work. experience training. [0003] The existing electric energy metering device training device has many relays and faulty operation nodes di...
