Problems solved by technology

Especially in the area between the main transformer and the radiator, due to the narrow space and the dense distribution of circulating oil pipes and cooling fins, the air flow is relatively difficult, and the oil flow temperature at the transformer outlet is high, which is prone to local heat accumulation problems
[0005] In addition, due to the high height of the main transformer room, the problem of insufficient exhaust power is likely to occur in the upper and middle spaces of the room, and the air flow in some areas is slow and prone to disorderly flow, and the hot air carrying heat gathers in the room and cannot be discharged in time
However, in the existing part of the ventilation system, the natural air intake louvers and the natural exhaust louvers are designed on the same side wall, which is prone to adverse results of airflow short circuit

Abstract

The invention discloses a composite ventilation cooling system of a main transformer room, including the main transformer room, an integrated oil-immersed transformer located in the center of the maintransformer roomroom, an air inlet system located below the integrated oil-immersed transformer and near the bottom of the main transformer room, an exhaust system located at the top of the main transformer room and a control system for intelligent control, the integrated oil-immersed transformer comprises a transformer body and radiators located on both sides of the transformer body, an air inlet is arranged at the bottom of one side wall of the main transformer room and an air outlet is arranged at the top of the main transformer room. The invention makes full use of external environmentalconditions to strengthen a ventilation effect, According to the operation of transformer and indoor ventilation condition, the ventilation mode can be adjusted dynamically, the indoor air flow can flow from bottom to top orderly, the utilization efficiency of cooling air can be improved, the service time of a mechanical fan is reduced, and the ventilation energy consumption can be reduced while the ventilation heat exchange effect of the transformer room can be improved.

Description

technical field [0001] The invention relates to a ventilation system for a main transformer room, in particular to a composite ventilation cooling system for a main transformer room. Background technique [0002] Because urban substations are located in urban areas, the land area is limited, and the impact of noise generated by operation on the surrounding environment must be considered, so electrical equipment such as main transformers are usually arranged indoors. For substations arranged indoors, oil-immersed transformers are often used, and the heat generated by the main transformer and radiator is a potential threat to its safe operation. In order to maintain the oil temperature of the transformer within a reasonable range and ensure smooth operation during the peak period of power consumption, it is very important to solve the ventilation and heat dissipation problems of indoor equipment. Therefore, it is necessary to discharge the heat dissipation during the operatio...
