Abstract

This invention discloses a smart meter durability testing device, belonging to the field of meter testing technology. It includes a test stand, on which a simulation test unit, a tightening variable control unit, and a data observation unit for detecting test results are installed. This invention uses high and low temperature testing, damp heat cycling testing, and salt spray corrosion testing modules in the simulation test unit to simultaneously simulate multiple extreme environments, accurately assessing the durability of the meter under complex operating conditions. Through a magnetically controlled connector combined with a tightening motor, the tightening stroke and pressure of the terminal screws can be precisely controlled, thereby exploring the impact of different tightening forces on the durability of the smart meter's terminals. A digital display power monitor synchronously records power consumption with the smart meter, directly comparing the test data with the actual value to quickly identify metering deviations. A camera periodically captures data from the display screen, tracking the meter's performance changes at different test stages and accurately locating the time point of failure.
