Abstract：Explosive interrupter is the core part of the explosive hybrid current limiting fuse(HCLF), which is a new kind of fault current limiter. This paper presents a novel kind of middle open explosive bus interrupter. The temperature rise simulation model is built based on ANSYS, and the explosive process simulation model is built based on LS-DYNA. Temperature rise experiment, explosive experiment and the 40 kA breaking experiment of integrated prototype verified the simulation results. Simulation and experiment results show that this kind of interrupter has many advantages such as low temperature rise at explosive materials, short departure time of fracture, high open speed, high current commutation arc voltage, strong dielectric recovery capability, etc. This kind of middle open explosive bus interrupter suit for high voltage high current utility.
