摘要
通过对现有直流计量技术的对比和分析,在闭环霍尔测量法的基础上,将霍尔采样的副边补偿线圈改造为多层线圈,并通改进的直流计量芯片对多层线圈的信号进行采集和运算,使改进后的直流计量电路提高了直流测量精度,扩大了测量范围,自动完成线圈消磁,并具备自动校准的能力。
Through comparison and analysis of existing DC metering technology, based on the closed-loop Hall measurement method, the secondary-side compensation coil of Hall sampling is transformed into a multilayer coil, and the multilayer coil. The signal is collected and calculated, so that the improved DC measurement circuit improves the DC measurement accuracy, expands the measurement range, automatically completes the coil demagnetization, and has the ability of automatic calibration.
