Abstract

The resistance of titanium diboride (TiB₂) particles will change significantly under the action of external force. So it can be used as a variable resistor for fault current limiting. For this purpose, TiB₂ material is required to withstand large currents and voltages. Based on the previous research, the resistance variation characteristics of material under large currents are studied in this paper. Through experiments, the voltage’s withstanding capability of a material is studied under large resistance. It is found that the maximum voltage that the material can withstand is related to its physical properties and material size. Then, a prototype based on the fast repulsion mechanism is made. Experiments are carried out on the current limiting capability of granular material under different sizes. The experimental results show that the granular material has good current limiting capability. The larger the material size is, the better the current limiting effect is.
