DLW100-12
SF6 outdoor ring network cabinet (primary and secondary integrated ring network cabinet)
The DLW100-12 type SF6 outdoor ring network box and the primary and secondary integrated ring network box are three-phase AC 50Hz power transmission and distribution equipment, used in power systems with a system voltage of 10kV. They can switch on and off no-load, load, and fault currents. Their main functions include power transmission and distribution, load switching, multi-level feeding, and automatic fault diagnosis and switching. They are applied to outdoor substations, compact substations, wind power stations, etc., such as municipal lighting, schools, hospitals, factories, residential areas, and temporary power supplies. They meet the requirements of the State Grid Corporation of China for the primary and secondary integration of power distribution equipment and effectively solve the problems of remote signaling jitter, poor compatibility and scalability of primary and secondary interfaces, and the addition of new metering terminals in the construction of power distribution automation.
