高压脉冲电流的测量方式主要是Rogowski线圈.B-Dot是一种非侵入式脉冲电流测量探针,但由于 B-Dot测量模型的建立以及应用标定等过程与实际应用环境密切相关,且对待测电流强度有严格的要求,目前还未见其在实际 kA 级短脉冲方面的应用研究.本文在对 B-Dot 的 kA 级短脉冲测量方法进行理论研究的基础上,设计了微型 B-Dot探针,并利用 B-Dot探针对 kA级短脉冲电流进行试验.试验结果表明,B-Dot 探针适用于 kA 级脉冲电流的测量,且与理论研究 结论一致.%Taking measurement by using Rogowski coil is the main method for high voltage pulse. B-Dot is a non-invasive measurement probe of pulse current, which bears many advantages in the measurement on the discharge circuit with compact structure and strictly specified parameters compared with general Rogowski coils. Nevertheless,the modeling of B-Dot and its calibration process are closely related to the practical application environments,and there are also strict requirements on the current intensity, the researches on its applications in kA level short pulse current measurement are seldom reported. This work aims to the preliminary exploration research on application of B-Dot in kA short pulse current. Based on analyzing the principle of kA level short pulse current measurement by using B-Dot, micro B-Dot probes are designed and tested on kA-μs level pulse current. The test results accord well to the theory analysis.
