Embodiment Construction
[0017] like figure 1 , 2 As shown, the air inlet 3 and the air outlet 4 are arranged on the same side wall 101 of the substation machine room 1, the air inlet 3 is arranged at the right end of the side wall 101 close to the bottom surface 105, and the air outlet 4 is arranged at the left end of the side wall 101 close to the top surface 104 , from the air inlet 3 to the substation machine room 1 with a small air volume and low speed, the direction of the airflow is towards the side wall 102 adjacent to the air inlet 3, and the air flows through the rebound of the side wall 102 adjacent to the air inlet 3 to form a flow on the bottom surface 105 The uniform low-speed airflow, the hot air buoyancy force formed by the heating of the electrical equipment 2 in the center of the machine room 1 drives the low-speed airflow up and flows through the electrical equipment 2, and the hot air flow heated by the electrical equipment 2 is discharged from the machine room 1 through the air o...

The invention relates to a transformer substation and an aeration-cooling method thereof, which is characterized in that an air inlet of a machine room and an air outlet of a machine room are arranged on the same side wall of the machine room of the transformer substation, the air inlet of the machine room is arranged on one end of the side wall close to the bottom, and the air outlet of the machine room is arranged on the other end of the side wall close to the roof. Small-quantity low-speed air flow is supplied to the machine room of the transformer substation from the air inlet of the machine room. After being rebounded by a side wall adjacent to the air inlet of the machine room, the low-speed air flow is driven by hot air buoyancy lift formed by the heating of electric equipment to rise to flow through the electric equipment; and hot air flow heated by the electric equipment is discharged out of the machine room from the air outlet of the machine room. By the invention, the controllable small-quantity low-speed air flow can be used for aeration-cooling of the electric equipment in a closed space, such as the transformer substation, and the like, thereby improving aeration-cooling efficiency, greatly reducing energy consumption and elimination noise pollution to surroundings.
Description
technical field [0001] The invention relates to a method for ventilating and cooling a closed space, in particular to an "indoor" or "underground" substation and a method for ventilating and cooling the substation. Background technique [0002] For a long time, most closed spaces such as "indoor" or "underground" substations or other similar places have been ventilated and cooled by installing powerful fans at the air outlets to ventilate and cool closed spaces through mechanical forced exhaust, or can also Install air conditioners in closed spaces to directly cool down. The above-mentioned ventilating and cooling method is not only unsatisfactory in effect, but also derives a large amount of other problems. For example, there are high-voltage cabinets, low-voltage cabinets, transformers and other electrical equipment in the computer room of the substation. Installing a powerful fan for ventilation and cooling will bring a lot of dust and salt or acid substances floating i...
