At present

the installation and placement of the complete set of overhead pole mounted switches for the primary and secondary integration of 10 kV distribution lines of power supply company is only based on experiences

and its installation quantity and location will directly affect the fault disposal effect of the distribution lines passing through forests and grasslands. In order to scientifically carry out switch installation and location

an optimal placement algorithm for the complete set of overhead pole mounted switches based on the improved discrete binary particle swarm optimization (DBPSO) is proposed. The test results show that the proposed algorithm can achieve the optimal switch location combination through fewer iterations

which can provide a scientific reference for the installation and location of the primary and secondary integrated overhead pole mounted switch in distribution network

and give full play to the actual effect of switch fault disposal.
