摘要
针对基于自收缩效应的液态金属限流器(LMCL)进行了限流特性的试验研究,得到了不同预期短路电流下的限流效果。试验结果表明,预期短路电流越大,限流效果越明显,在预期短路电流峰值为20 kA,电流上升率为10 A/μs的情况下,LMCL能够在1 ms内自动起弧,并通过快速上升的电弧电压迅速将短路电流限制在12 kA。
The experimental study was done for the liquid metal current limiter(LMCL) based on the self pinch effect,and the current limiting effect was obtained under different prospective short current.It indicated that the current limiting effect got better with the increase of prospective short current.The arc ignited in LMCL within 1 ms under the 20 kA prospective current and 10 A/μs rise rate,and the short current was limited to 12 kA due to the rapid increase of arc voltage.
