Abstract: Provided by the present application are a Direct Current (DC) micro-grid system, a charging loop circuit and a control method thereof. The charging loop circuit selectively connects a charging loop to a first side loop or a second side loop through a set of switches.

Abstract: A modular energy-dissipating fabricated structure for a transmission tower includes a base, two T-shaped beams, a vibration damping mechanism, a connection plate, and four supporting beams. The vibration damping mechanism slides to generate the damping force and energy dissipation. The larger the displacement of the vibration damping mechanism, the greater the damping force provided by the system. This effectively reduces vibration of an upper structure of the transmission tower, and lowers a probability of damaging the upper structure in a natural disaster. The modular energy-dissipating fabricated structure realizes hierarchical control under different loads. Under an action of a dynamic load such as a strong wind, a small sliding range of the vibration damping mechanism can realize vibration damping and energy dissipation purposes of the structure. When a strong dynamic load such as an earthquake is applied to the structure, the vibration damping mechanism reduces an impact on the structure.
