In order to solve problems that the low coincidence success rate of the automatic reclosure of distribution network and short-circuit current has a large impact on the system when it coincides with the permanent fault, a shunt resistance type of adaptive reclosing switch is proposed. In order to improve the success rate of reconfiguration of the distribution network. By selecting the appropriate shunt resistance, the switch can not only suppress the magnetizing inrush current, limit the short-circuit current, reduce the system impact, but also use the current characteristics flowing through the shunt resistance to determine whether there is a permanent fault in the downstream, and realize the adaptive reclosing. The shunt resistance type adaptive reclosing switch can be separately applied to the power distribution switch to replace the original reclosing mode, and as a switch with protection function, the safety of the fault handling process is improved.
