摘要

电表的重要评估之一是太阳辐射测试,通常使用太阳模拟器进行。这项工作的重点是改造埃及国家标准局(NIS)的气候室(MKF-240),使其成为太阳能模拟器。为了复制太阳测试条件,在 MKF-240 气候箱中安装了铝板和石英卤钨灯 (QTH) 等增强设备。为了确定达到测试标准所需的最佳灯管数量,并实现测试区域内的最佳均匀性,进行了多次实验测试。太阳能模拟器的设计辐照度最高可达 1066 W/m2,可通过调整照明灯的数量以及灯与被测设备之间的距离来控制输出辐射。在最大辐照度下,模拟器的辐射均匀度高达 91.5%。为了验证其功能,在户外电表上进行了太阳辐射测试,使其承受不同的负载和不同的辐射值。作为整个评估过程的重要组成部分,电表的准确性得到了精确记录和分析。

Adopted Climatic Chamber Solar Simulator for Testing Solar Radiation Effects on Electricity Meters at NIS

Adopted Climatic Chamber Solar Simulator for Testing Solar Radiation Effects on Electricity Meters at NIS

One of the crucial assessments for electricity meters involves the solar radiation test, typically conducted using solar simulators. This work focuses on the modification of the climatic chamber (MKF-240) at the Egyptian National Institute of Standards (NIS) to serve as a solar simulator. To replicate solar test conditions, enhancements such as an aluminum plate and quartz tungsten halogen (QTH) lamps have been integrated into the MKF-240 climatic chamber. Several experimental trials were undertaken to ascertain the optimal number of lamps required to meet testing standards and achieve optimal uniformity within the test area. The solar simulator, designed for irradiance levels up to 1066 W/m2, allows for control of output radiation by adjusting the number of illuminated lamps and the distances between lamps and the unit under examination. At maximum irradiance, the simulator demonstrates a remarkable 91.5% uniformity of radiation. To validate its functionality, the solar radiation test was executed on an outdoor electricity meter, exposing it to different loads and varying radiation values. The accuracy of the meter was precisely recorded and analyzed as an essential component of the overall assessment process.
