摘　　要：自积分式罗果夫斯基电流线圈是在输出端并联一的采样电阻,并选用磁导率小的铜或铝作为与线圈配合的待测母线。选择采样电阻,既要信噪比好,又要避免产生过大的测量信号。带磁芯的罗氏线圈应尽可能减小线圈内阻。宜选用温度膨胀系数小的材料作为骨架,也可根据试验测出温度对线圈输出电压的影响,在不同温度下进行修正。其屏蔽盒应用主气隙,防止原电流产生的磁场集中在屏蔽壳的金属板内。Self-integral Rogowski current coil is used parallel sampling resistance in the out-port, and is selected the small magnetic conductivity copper or aluminum as the generatrix to be measured. Sampling resistance is both the signal to noise ratio to be good and avoiding to produce the oversized survey signal~ The magnetic core Rogowski Current Coil should reduce inner resistance as far as possible~ It is suitably selected the small temperature expansion coefficient material to take the skeleton, According to the temperature to the coil output voltage influence, the revision is carried on under the different temperature. Its shielded box should be used the main air gap and prevent the primary current to produce the magnetic field concentrating in the shield shell metal plate.
