摘　　要：国标GB/T15576-2020《低压成套无功功率补偿装置》要求生产企业对每台低压无功功率补偿装置进行“工频过电压保护试验”和“缺相保护试验”(无缺相保护的装置除外)。[1]由于低压无功功率补偿装置的容量大,该试验会增加企业的生产能耗和成本。本文通过对上述两个试验本质的分析,提出了可以用容量较小的电容器取代低压无功功率补偿装置中的电力电容器进行试验,达到相同的效果,同时提出了一种检测设备的设计方案。The national standard GB/T 15576-2020 "Low-voltage Reactive Power Compensation Assemblies" requires the manufacturer to carry out "power frequency overvoltage protection test" and "open phase protection test" for each low-voltage reactive power compensation assemblies(except the assemblies without open phase protection).Due to the large capacity of low-voltage reactive power compensation assemblies,the test will increase the production energy consumption and cost of enterprises.Based on the analysis of the essence of the above two tests,this paper proposes that the power capacitor in the low-voltage reactive power compensation assemblies can be replaced by a capacitor with smaller capacity to achieve the same effect,and puts forward a design scheme of detection equipment.
