【摘要】 在电力系统中,电子式电流互感器被广泛应用于电流测量。本系统采用新型高精度Rogowski线圈作感应元件,设计一种新型模拟信号处理系统对线圈输出电压信号进行处理,完成电流的测量和过载保护功能。从而简化设计过程、降低生产成本。从试验结果看传感头精度可达到0.2级要求。更多还原

【Abstract】 In power system,electronic current transformer has been used to measure current widely.This system adopted new high precise Rogowski coil as sensor components,and designed a new analog system to deal with the signals which exported from Rogowski coil,to fulfill measuring current and over load protection.So we could predigest design process and reduce production cost,and we can draw conclusion by experiment result that the precision of this sensor head could reach 0.2 level.更多还原
