Technical Field

The invention relates to the technical field of transformer heat dissipation, in particular to a high-capacity transformer cooling system cooled by a finned radiator.

Background

The transformer cooling means that heat generated by a transformer in operation is dissipated by a certain method, the heat generated by loss in a winding and an iron core when the transformer is in operation must be dissipated in time so as to avoid insulation damage caused by overheating, the ratio of the outer surface area to the volume of the transformer is relatively large for a small-capacity transformer, and the heat can be dissipated by radiation and natural convection in a self-cooling mode.

For example, application No.: the invention discloses a Chinese patent of CN201711052785.7, and provides a transformer cooling device, belonging to the field of transformers. The cooling device mainly comprises a cooling box, a first conveying pipe, a second conveying pipe and a valve adjusting device. The transformer, the cooling box, the first conveying pipe and the second conveying pipe form a closed loop. The second conveying pipe is provided with a flow control valve, and the valve adjusting device is used for adjusting the opening of the flow control valve. When the cooling device is used, the oil pump on the cooling box is started, and the oil pump provides power for the flow of cooling media in the cooling device. The cooling medium is conveyed into the transformer through the first conveying pipe, carries away heat of the transformer after heat exchange in the transformer, and then returns to the cooling box through the second conveying pipe for cooling. When the temperature of the winding rises, the valve regulating device increases the opening degree of the flow control valve; conversely, the opening degree of the flow direction control valve is decreased. Therefore, the transformer cooling device can dynamically adjust the flow of the cooling medium in the pipeline; not only can ensure the cooling effect, but also can save energy as much as possible.
