The invention relates to the technical field of auxiliary power supplies for electric energy meters, in particular to an automatic power consumption test system and a test method for dual-channel auxiliary power supplies for electric energy meters, which include a main control unit, a measurement unit, a switch control circuit, a first sampling resistor and a second sampling resistor. The automatic test system can not only realize production automation, improve production efficiency and product quality; but also the system can automatically upload the measurement results to the server for storage, which can be traced later, which solves the fatigue effect caused by the traditional manual recording method. Problems that lead to data recording errors and data loss make the quality of the product more reliable. The present invention also provides an automatic test method for the power consumption of the two-way auxiliary power supply of the electric energy meter. The test method can realize the power consumption test of the automatic two-way auxiliary power supply. The installation and disassembly of the machine reduce the production cost and ensure the reliable quality of the product.
Description
technical field [0001] The invention relates to the technical field of electric energy meter auxiliary power supply, in particular to an automatic test system and a test method for power consumption of a two-way auxiliary power supply of electric energy meter. Background technique [0002] The commonly used "battery replaceable single-phase smart energy meter" generally has two auxiliary power sources: a super capacitor and a replaceable lithium battery. Reliable operation of the internal clock of the energy meter and normal operation of some other functions. Because the capacity of the auxiliary power supply is limited, the working power consumption of the auxiliary power supply must be kept within a certain range. Although its working power consumption is determined by the design, some external manufacturing process factors (such as problems such as virtual soldering and virtual connections) may cause It will lead to excessive power consumption, so the working power consu...
