Flexible combination of box-type substation

Box-type substation has a compact structure, and each box constitutes an independent system, which makes the combination flexible and changeable. On the one hand, we can use all box-type, that is, all 35kv and 10kv equipment are installed in the box to form a full box-type substation; we can also use only 10kv switch box, 35kv equipment is installed outdoors, and 10kv equipment and control system are installed in the box. This combination is particularly suitable for the transformation of old stations in rural power grid transformation, that is, the original 35kv equipment is not moved, and only one 10kv switch box is installed to meet the requirements of unattended operation. In short, there is no fixed combination mode for box-type substations, and the user unit can freely combine some modes according to the actual situation to meet the needs of safe operation.
