Description

Technical Field

[0001] The present invention relates to the field of power quality module detection, and in particular to a power quality module intelligent optimization control system. Background Art

[0002] The power quality module is an important function expansion module of the smart IoT electricity meter. It uses the voltage and current sampling waveform data on the line for analysis and calculation, monitors the power quality from multiple dimensions such as voltage deviation, harmonic content, frequency deviation, flicker, three-phase voltage imbalance, etc., and provides real-time data support for management and control.

[0003] The detection module can detect the power quality module sent for inspection after sampling. In the actual detection process, if there is a large electromagnetic interference, the capacitor inside the power quality module is damaged, the electronic components are short-circuited, etc., the power quality module will be in a high temperature condition; when the power quality module is in a high temperature condition for a long time, not only will there be a measurement error, but it will also cause itself to be damaged, which has serious safety hazards. Therefore, it is necessary to extract the temperature of the detected power quality module in real time, and the extracted temperature value can be used as a reference. Generally, the temperature value is extracted through a temperature sensor; however, the existing temperature sensors are directly welded on the internal mainboard of the detection module. On the one hand, the temperature sensor is far away from the power quality module, and the temperature extraction accuracy is not enough; on the other hand, when the temperature sensor fails or needs regular maintenance, the temperature sensor needs to be disassembled and replaced. The disassembly process is likely to cause damage to the pad on the internal mainboard, which in turn causes the internal mainboard to be scrapped because the temperature sensor cannot be welded. Therefore, it is necessary to optimize the installation structure of the temperature sensor. Summary of the invention
