Problems solved by technology
[0003] When the existing power meter is running, the internal electronic components work in a closed environment, which leads to the accumulation of heat generated by the operation, which makes the temperature inside the meter gradually increase. The electronic components work in a high temperature environment, which not only reduces the measurement of the meter Accuracy, while shortening the service life of the device, a small number of instruments will add heat dissipation holes, but after long-term operation, dust and impurities are easy to accumulate on the heat dissipation holes, resulting in blockage caused by poor air circulation, reducing heat dissipation efficiency, making existing power meters reduced availability of
