The generator cabin is located at the top of the tower drum, the wind wheel is connected at one end of the cabin, and the generator is located in the cabin, driven by the wind wheel to generate electricity. With the long-term operation of the equipment, the key components may be damaged, especially the frequency converter is crucial in the power generation process, and its replacement process is particularly complex. The frequency converter is large in size and weight, and needs to be fixed with bolts during disassembly and replacement, which is tedious and easy to cause fatigue of the workers and has the risk of falling. Therefore, professional tools must be provided to ensure the safety and efficiency of replacement.
