Description

Technical Field

[0001] The utility model relates to the technical field of wind power generation, in particular to a fixing device for a wind power tower busbar. Background Art

[0002] The wind turbine tower is an important part of the wind turbine generator set. It connects the wind turbine generator set and the foundation ring, bears the weight of the wind turbine generator set weighing hundreds of tons on the upper part, and provides the space required for the maintenance, power transmission and transformation of the wind turbine generator set. There is usually a bus duct inside the wind turbine tower to transmit the electricity generated by the wind turbine generator set. The bus duct needs to be fixed on the inner wall of the wind turbine tower to ensure its stability and safety. At present, there are two main ways to fix the bus duct of the wind turbine tower: one is to directly weld the bus duct to the inner wall of the wind turbine tower. This method is simple and convenient, but it is easy to cause deformation and damage to the bus duct and the wind turbine tower; the other is to use a support frame to fix the bus duct on the inner wall of the wind turbine tower. This method can avoid the problems caused by welding, but the structure of the support frame is complex, installation and adjustment are difficult, and it cannot effectively prevent the vibration and displacement of the bus duct during operation.
