Problems solved by technology

The traditional water-cooling system is to install a water-cooling device on the side of the dry-type transformer shell, and set the air inlet and outlet on the installation surface. This method only cools the transformer by cooling the air inside the dry-type transformer shell, and the heat transfer efficiency is low, thereby increasing The energy consumption of the water cooling device

Abstract

The invention relates to an air-immersed transformer water-cooling system which comprises a totally-enclosed type air-immersed transformer protecting housing; a water-cooling device is arranged at the side of the shell; and the air inlet and the air outlet of the water-cooling device are arranged at the installing side. The interior of the shell is provided with an air sending passage which is connected with the air outlet of the water-cooling device and provided with a plurality of chimney fans. The chimney fans aim at coils and iron cores of the air-immersed transformer. The interior of the totally-enclosed type shell is provided with a horizontal insulating clapboard which is arranged between the air inlet and the air outlet of the water-cooling device; and the insulating clapboard is provided with a diversion hole on the periphery of the coil of the air-immersed transformer. The system further improves the cooling effect of the water cooling device and achieves the purpose of energy consumption reduction.

Description

technical field [0001] The invention relates to a dry-type transformer water cooling system. Background technique [0002] For electrical equipment such as dry-type transformers that generate a lot of heat during work, when they are installed in some special environments with unsatisfactory ventilation effects, or when the transformer requires a high protection level and cannot meet natural ventilation, some special cooling methods will be adopted. To ensure the normal operation of the transformer, water cooling is the cooling method often used in these cases. The traditional water-cooling system is to install a water-cooling device on the side of the dry-type transformer shell, and set the air inlet and outlet on the installation surface. This method only cools the transformer by cooling the air inside the dry-type transformer shell, and the heat transfer efficiency is low, thereby increasing energy consumption of the water cooling device.
