Outdoor prefabricated substation for urban power grid transformation

Abstract

The invention relates to the technical field of power equipment, and concretely relates to an outdoor prefabricated substation for urban power grid transformation. Theoutdoor prefabricated substationcomprises a prefabricated base, a box base and a substation box, a plurality of lower fixing sleeves and damping seats are welded to the upper end face of the prefabricated base, and a plurality of upper fixing rods and damping balls are welded to the bottom end of the box base; the substation box is fixed to the upper end of the box base, the interior of the substation box is sequentially dividedinto a high-pressure chamber, a transformer chamber and a low-pressure chamber through a first galvanized plate and a second galvanized plate, a heat exchange plate is fixed to the top end of the substation box, a heat exchange container is fixed to the upper end face of the heat exchange plate, and the outer wall of the heat exchange container communicates with a liquid inlet pipe and a liquid outlet pipe; and a ceiling is fixed to the outer wall of the heat exchange container, and a plurality of heat exchange fins are fixed to the bottom end of the heat exchange plate. The heat exchange container can be adjusted to dissipate heat and cool or heat and melt a snow layer according to the change of the weather environment, and the adaptive capacity is high; and meanwhile, assembling is veryconvenient, stability is excellent, and excellent shock resistance is achieved.

Description

technical field [0001] The invention relates to a dispatching system in the technical field of electric power equipment, in particular to an outdoor prefabricated substation for urban power grid transformation. Background technique [0002] Outdoor prefabricated substation is a new type of power supply supporting equipment. With the deepening of the transformation and construction of my country's urban and rural power grids, it is necessary to design a technical support product that meets the requirements of automated development of grid intelligent remote data collection, improves the reliability of power supply, and increases the aesthetics of the city to replace the original spider-like overhead. The product of the incoming line is designed to be close to the load center, so as to save the investment in electrical equipment and cables, so as to realize the technical optimization of the power transmission and distribution system, and has strong flexibility and reliability. ...

Problems solved by technology

This utility model has a good heat dissipation effect, reduces the high temperature inside the substation, and provides a good working environment for the equipment inside the substation; however, this utility model still has some shortcomings: it cannot dissipate heat or Melting, when the weather is hot, the electrical components inside the substation are in a high-temperature environment, causing short-circuit fire accidents, and in rainy and snowy weather, the roof of the substation is easy to accumulate snow layers and cause collapse accidents; the impact force from multiple angles cannot be buffered, Poor shock resistance
