Electric power centralized maintenance carriage and electric power maintenance engineering truck

The invention relates to an electric power centralized maintenance carriage and an electric power maintenance engineering vehicle. Supply buses in the electric power centralized maintenance carriage comprise at least two of a power supply bus, an air pressure bus and a hydraulic bus, and the supply buses comprise a bottom supply bus and a top supply bus which are laid on the bottom carriage wall and the top carriage wall respectively. The vertical bus is arranged on the front end compartment wall or the side compartment wall and is connected with the bottom supply bus and the top supply bus to form an integral passage, and the bottom supply bus and the top supply bus extend to the rear end of the compartment wall or the position close to the rear end of the compartment wall respectively. And more than two external ports which are spaced in the front-back direction are respectively arranged on the front-back plate. Thus, driving form demand types which can be adapted to the supply bus are enriched, different d
