This paper analyzes the composition of electrical loads in railway sections and the adaptability of direct current(DC)power distribution.By investigating the fundamental topological structures of DC distribution systems,busbar connection types,the impact of voltage levels on power supply capacity and personal safety,the selection of voltage withstand levels for DC distribution cables,and DC grounding configurations,the paper delves into the design of DC power distribution for electrical loads in railway sections.Furthermore,a technical solution tailored for the DC power distribution of electrical loads in railway sections is proposed.
