Metering error automatic verification system for multiple types of single-phase electric energy meters

Abstract

The invention provides a metering error automatic verification system for multiple types of single-phase electric energy meters, which belongs to the technical field of electric energy meter verification. The system comprises an electric meter conveying frame, a dial plate conveying device, an electric meter supporting device and a calibrating device, wherein the calibrating device comprises a base, an auxiliary probe assembly, a pulse detection assembly and a calibrating terminal, 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, and the auxiliary probe assembly comprises an auxiliary probe and is used for acquiring metering data of the to-be-verified electric energy meter. The pulse detection assembly comprises a pulse acquisition module which is used for acquiring metering data output by the to-be-verified electric energy meter in a pulse signal form. The system can meet verification requirements of various electric energy meters at the same time, especially verification of 2009-edition and 2013-edition intelligent electric energy meters and IR46-standard intelligent electric energy meters, a plurality of 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 electric energy meter verification, and in particular relates to an automatic verification system for measurement errors of multi-type single-phase electric energy meters. Background technique [0002] At present, smart energy meters with integrated design are widely used. However, when such energy meters fail, the only feasible way to ensure the smooth progress of power metering is to replace the energy meters. Moreover, in order to prevent inaccurate energy measurement caused by tampering with the energy meter program, the energy meter software does not allow online upgrades. The integrated design of smart energy meters not only has a short service life, but also when new requirements are put forward for the functions of energy meters, the replacement of a large number of energy meters will inevitably result in waste of resources and a reduction in social benefits. [0003] In 2012, the International L...
