本文对罗氏环的有关理论做了简单介绍,阐述了有关的设计知识与制作实践。这种罗氏环可用来测量高达百万安培量级的脉冲电流。本文研制的罗氏环有几个毫微秒的上升前沿,灵敏度约9.9×10~(-3)V/A,在强辐射环境与EMP环境下工作。
This article gives a brief introduction of the Roche ring theory, expounds the relevant design knowledge and production practice. This Roche ring can be used to measure pulsed currents up to millions of amps. Roche ring developed in this paper has several nanosecond rising front, the sensitivity of about 9.9 × 10 -3 V / A, in a strong radiation environment and EMP environment work.
