Research on the material of current-carrying vessel used for current transfer type fault current limiter

Abstract

In recent years, there has been more and more research on current transfer type fault current limiter. Titanium diboride is used as the pressure-controlled materials in the field of current transfer, which has high application value and research significance. The current transfer type fault current limiter has two working states: when the circuit is operating normally, a certain amount of current passes through the current limiter in a steady state; when a circuit fault occurs, the current transfer type current limiter acts to form a circuit potential difference and promote current transfer to other branches. Titanium diboride, as a material for the normal operation of the transfer fault current limiter access circuit, will produce current heating when it is supplied with current. This phenomenon may affect the entire circuit and the life of the current limiter. This article uses Ansys Simulation analysis to study the thermal phenomenon of titanium diboride passing current has guiding significance for the production and realization of current transfer fault current limiter.
