Metering error automatic verification system for multi-type three-phase electric energy meter

Abstract

The invention provides a metering error automatic verification system for a multi-type three-phase electric energy meter, which belongs to the technical field of electric energy meter verification. The system comprises a mounting platform and a verification terminal, wherein an electric meter conveying groove is formed above the mounting platform, an electric meter conveying belt is arranged in the electric meter conveying groove, and an electric meter lifting platform is arranged at the bottom of the electric meter conveying groove; a plurality of feeding seats are arranged on the two sides of the electricity meter conveying groove in an arrayed mode and can feed in the direction perpendicular to the central axis of the electricity meter conveying groove. A verification device is arranged on the feeding seat and comprises a base, an auxiliary probe assembly and a pulse detection assembly, and a current and voltage probe is arranged on the base. The auxiliary probe assembly is arranged on the base and can slide back and forth along the base. The pulse detection assembly obtains metering data output by the to-be-verified electric energy meter in a pulse signal mode. The system can meet the verification requirements of various three-phase electric energy meters at the same time, multiple different verification assembly lines do not need to be arranged, the utilization rate of verification equipment is improved, and the verification cost of the electric energy meters is reduced.

Description

technical field [0001] The invention belongs to the technical field of verification of three-phase electric energy meters, and in particular relates to an automatic measurement error verification system for multi-type three-phase electric energy meters. Background technique [0002] At present, intelligent three-phase electric energy meters with integrated design are widely used. However, when this three-phase electric energy meter fails, the only feasible way to ensure the smooth progress of power metering is to replace the three-phase electric energy meter. Moreover, in order to prevent inaccurate electric energy measurement caused by tampering with the three-phase electric energy meter program, the three-phase electric energy meter software does not allow online upgrades. The integrated design of intelligent three-phase energy meters not only has a short service life, but also when new requirements are put forward for the functions of three-phase energy meters, the replac...
