Problems solved by technology

[0004] Most of the currently used aging test devices can only test several electric energy meters at the same time, or there are differences in the consistency of the electric energy meter receiving voltage and power signal
Moreover, when multiple energy meters are subjected to aging tests at the same time, errors will be formed due to the inconsistency of the timing of each energy meter.

Abstract

Provided in the invention is an apparatus for detecting aging of an electric energy meter. The detection apparatus comprises a detection platform arranged horizontally, a first socket arranged at the detection platform, a second socket arranged at the detection platform, and a plurality of installing positions for placing electric energy meters; and voltage input terminals of the plurality of installing positions are connected in parallel; and current output terminals are connected in series. With the apparatus, because the plurality of electric energy meter installing positions are arranged and a space-time switch and a relay are used for controlling testing time precisely, so that aging testing on the batch of electric energy meters can be carried out accurately.

Description

technical field [0001] The invention relates to an electric energy meter aging detection device, in particular to an electric energy meter aging detection device capable of performing aging detection on batch electric energy meters. Background technique [0002] As we all know, electric energy meters are used in various electronic test sites, and its importance is self-evident. But each electric energy meter needs to be tested for a series of items before leaving the factory, one of which is the aging test. [0003] Each energy meter needs to be aged for 12 hours in an aging room with a temperature of 55°C. This is a long-term test project, so there are high requirements for the improvement of test efficiency and the accuracy of time measurement. [0004] Most of the currently used aging test devices can only test several electric energy meters at the same time, or there are differences in the consistency of the voltage and power signals received by the electric energy met...
