Experimental Research on Parallel Current Limiting Characteristic Based on Liquid Metal Current Limiter

针对自收缩型液态金属限流技术,进行了大量的试验研究。为了解决液态金属限流器在燃弧限流过程中装置内部气压过高的问题,通过液态金属限流器并联阻抗吸收回路和并联结构相同液态金属限流器吸收回路两种方式实现对液态金属限流器的保护。试验研究了并联不同能量吸收回路时液态限流器的限流特性和分流特性,为液态金属限流器在实际工程应用中提供参考。

This thesis focuses on the experimental research on liquid metal current limiter of self-shrink effect.In order to control the pressure inside the liquid metal current limiter during the arcing current limiting process,the liquid metal current limiter is protected by paralleled with energy absorption branch,including paralleled with impedance and liquid metal current limiter in the same structure. The current limiting characteristic and current diversion characteristic of parallel liquid metal current limiter were researched to provide guidance for the engineering application of liquid metal current limiter.
