Hua-style box-type substation not only combines the miniaturization advantages of American-style box-type substations and the automation configuration advantages of European-style box-type substations, but also forms its unique safety, reliability, convenience and environmental protection characteristics. Hua-style box-type substations are particularly suitable for wind power and photovoltaic projects, fully demonstrating their application potential in the new energy field. The structure generally adopts a "品" shaped structure. The high-voltage side configuration of Hua-style box-type substations is different from that of American-style box-type substations. The high-voltage distribution room mainly uses air-insulated ring main units, which are equipped with many components such as disconnectors, vacuum circuit breakers, current transformers, zinc oxide arresters, cable heads, grounding switches and live display devices. On the low-voltage side, the configuration of Hua-style box-type substations is consistent with that of American-style and European-style box-type substations.
