The station sites of the transformer substations are often far away, and the situations that no water supply network exists around the transformer substations and no well drilling condition exists exist, so that the current situation that no water is available has to be faced. In areas with abundant rainfall, the use of rain is one of the methods to alleviate the difficulties in substation use. However, after the outdoor transformer substation is constructed, the water permeable area of the construction field area, the water permeability of the earth surface and other underlying surface conditions are changed greatly, so that the production flow in the rainfall field area is increased, and the convergence speed is accelerated. The surface runoff of a transformer substation field is controlled by simply utilizing the traditional drainage and flood removal measures, rain and flood cannot be converted into available resources, and the flood control and flood removal pressure of peripheral areas is increased by a large amount of concentrated drainage in a short time. Finally, the transformer substation faces the embarrassment that water cannot be used but water cannot be used.
The power distribution device field is an important component of the transformer substation field, occupies most area of the transformer substation field, and is a key part for increasing seepage and storage and reducing runoff. At present, the prior art is concerned with the problem of rain collection and utilization in the transformer substation field, but the technology is not concerned with the problem of field control and utilization of runoff by using a power distribution device.
