摘要
Ⅱ型采集的设计过程中,通常采用硅钢变压器作为电源模块的关键器件,但设计过程中往往忽略了采集器可能对电能表产生的干扰,会造成电能表的计量不准。从Ⅱ型采集器的结构原理及锰铜采样电能表的工作原理出发,分析了Ⅱ型采集器对电能表计量准确度的影响原因,提出了对Ⅱ采集器及电能表的改进建议,并对现场安装方式提出了建议,避免采集器对电能表产生干扰。
In the design of Type II collector, silicon steel transformer is usually used as the key components. However, the interference caused by the collector to impact power meters is commonly overlooked by designers. This article analyzes the influence of the Type II collector on power meters based on the structural principle of type II collector and the operational principle of the power meter. Based on these analyses, suggestions to improve type II collector and power meter, as well as their on-site installation for avoiding the interference caused by the collector to impact power meters are presented.
