[0002] The transformer fan is a device used to cool the transformer. The transformer generates heat during operation. In order to ensure its normal operation and extend its service life, heat dissipation is required. Usually, the transformer fan is installed on the outside of the transformer. For example, the cross-flow transformer fan is usually installed on both sides of the bottom of the transformer. When the transformer fails and needs maintenance, the cross-flow transformer fan needs to be maintained or replaced.

[0003] However, when workers perform maintenance on the fan, they usually disassemble the transformer fan from the fan mounting frame, then perform maintenance on the fan. After the maintenance is completed, the fan is reinstalled on the mounting frame, which increases the maintenance time of the workers and reduces the maintenance efficiency of the fan. For this reason, a mounting structure for a transformer fan is proposed. Utility Model Content

[0022] According to the above technical solution, the worker installs the fan on the placement rack 10, and then moves the support member 17 downward to move the bottom plate 16 to the ground. At this time, the bottom plate 16 is located on the same horizontal line as the roller 14 to prevent the roller 14 from moving, thereby ensuring the normal use of the fan. When the fan needs to be maintained, the support member 17 is moved upward to make the bottom plate 16 enter the receiving groove 15, and then the placement rack 10 is moved. The worker maintains the fan on the moved placement rack 10 without reinstalling the maintained fan, thereby improving the maintenance efficiency.
