Problems solved by technology

Therefore, the technology suitable for underground use of fully buried substations is still immature: the heat dissipation and ventilation are not smooth, the heat cannot be dissipated, and there are potential safety hazards
[0003] In order to ensure the ventilation and heat dissipation in the substation box, it is necessary to set up heat dissipation and ventilation windows on the groun

Abstract

The invention relates to a total-buried transformer station drainage ventilation apparatus, and especially relates to a drainage ventilation apparatus of a total-buried prefabricated box type transformer station. The apparatus comprises water accumulation boxes, water accumulation box covers and landscape ventilating ducts are arranged above the water accumulation boxes, the water accumulation box covers are provided with water discharging holes, the two water accumulation boxes are connected through a drainage pipe, the water accumulation boxes are internally provided with non-return valves, the non-return valves are composed of floating balls and mesh enclosures, the upper ends of the mesh enclosures are provided with rubber sleeves and are connected with a first blower fan pipeline or a second blower fan pipeline through the rubber sleeves, the other end of the first blower fan pipeline is provided with first blower fans, the other end of the second blower fan pipeline is provided with second blower fans, the bottom end of the second blower fan pipeline is provided with a water level gauge, and the water level gauge is connected with the water accumulation boxes through a water pump pipeline. The total-buried transformer station drainage ventilation apparatus is scientific and reasonable, is high in innovation, quite good in ventilation draining performance and high in heat dissipation efficiency, and is safety and reliable in application.

Description

technical field [0001] The invention relates to a drainage and ventilation device for a fully buried substation, in particular to a drainage and ventilation device for a fully buried prefabricated box-type substation. Background technique [0002] The substation is an indispensable and important part of the power system. It mainly plays the role of distributing electric energy, regulating voltage, protecting the safety of the power grid, and improving the power supply quality of the power grid. Prefabricated substations generally include a transformer room, a high voltage room, a low voltage room, and some power facilities with high heat generation, such as high-power frequency conversion products, capacitors, inverters, etc. Therefore, the technology suitable for underground use of fully buried substations is still immature: the heat dissipation and ventilation are not smooth, the heat cannot be dissipated, and there are potential safety hazards. [0003] In order to ensur...
