Abstract

The liquid metal current limiter based on the pinch effect has many advantages in the current limit, and has good application prospect in the power system. In this paper, a new LMCL which can string the cavity partition into the current limiting circuit is designed. The current limiting mechanism of the new LMCL is verified, and the arcing characteristics of the LMCL whose cavity partition are insulating material and conductive material are compared by experimental research. The experimental results show that the cavity partition material with higher electrical conductivity can effectively reduce the intensity of arc combustion, and the cavity partition can be connected to the circuit to limit the current, which provides an important reference for the optimal parameter design of the LMCL.
