Description

Replacement device Technical Field The utility model relates to the technical field of fan operation and maintenance, in particular to a replacement device. Background In the field of wind power generation, the replacement work of a fan transformer is an important part in the operation and maintenance work of a fan. Currently, when fan transformer replacement is performed, large-scale hoisting facilities are commonly used to accomplish this task. With the continuous development of the wind power industry, the installed capacity of the fan has an increasing trend. The increase of the installed capacity of the fan enables the height of the fan to be continuously increased. This change presents new challenges for the replacement work of the fan transformer. Because the height of the fan is increased, when a large lifting facility is used for replacing the transformer, the load of the lifting facility required for meeting the lifting requirement is required to be larger so as to bear the weight of the heavier transformer, and meanwhile, the lifting height is correspondingly increased so as to achieve the replacement of the fan transformer at a higher position. However, the increase of the load and the lifting height of the large-scale lifting facility increases the operation and maintenance cost of the fan.
