The invention relates to the technical field of an electric energy meter auxiliary power source and specifically relates to an electric energy meter double circuit auxiliary power source power consumption automatic test system and test method. The system comprises a master control unit, a measurement unit, an on-off control circuit, a first sampling resistor and a second sampling resistor. Via theautomatic test system, production automation can be realized, production efficiency and product quality can be improved, a measurement result can be automatically uploaded to a server and then storedvia the system, and later-on tracing operation can be performed; a problem that wrong data recording and data loss are caused by fatigue effect generated by a conventional manual recording mode, andreliability of product quality can be improved. The invention also provides an electric energy meter double circuit auxiliary power source power consumption automatic test method via which power consumption of a double circuit auxiliary power source can be realized automatically, high intelligentization can be realized, manual battery installation and dismounting is not needed in power consumptiontesting processes, production cost is lowered, and reliable product quality is ensured.
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...
