摘　　要：介绍了罗戈夫斯基线圈(罗氏线圈)电流传感头的测量原理及特点,对影响传感头性能的外界干扰磁场、被测导线位置等因素进行了详细分析,并给出了改善措施。设计了一种基于印制电路板(PCB)骨架的罗氏线圈,在信号处理电路的基础上对其进行了试验研究。结果显示,PCB型罗氏线圈测量电流精度高,有较好的抗外界干扰能力,符合设计要求。The measuring principle and characteristics of Rogowsky coil current sensor were introduced. The factors that might influence the sensing head such as the external disturbing magnetic field and the location of the wire were analyzed in detail while the improvement measures were given. Designed a Rogowsky coil based on printed circuit board （PCB） and tested it on the basis of signal processing circuit. The results show that the PCB type Rogowsky coil has high accuracy for current measurement and sound capability to resist external disturbance which meets the design requirements.
