Problems solved by technology
The truss tower was widely used in early wind turbines. Compared with the cylindrical tower, the truss tower is simple to manufacture, low in cost, and convenient in transportation. The main disadvantage is that the tower is too open, and maintenance personnel go up and down the tower. Unsafe, nowhere to put electrical equipment

The invention provides a trussed wind turbine tower and a wind turbine unit with the same. The tower comprises a trussed tower body, an equipment room used for placement of electrical equipment and a safety ladder stand, an engine room is arranged at the top end of the tower body, and the safety ladder stand penetrates the inner portion of the tower body and is arranged between the top of the equipment room and the engine room. By the trussed tower structure, the trussed wind turbine tower has the advantages of material and cost saving and mechanical property, more importantly, transportation cost can be saved greatly, field production and mounting can be realized, the tower can be mounted in sections on the ground prior to lifting, the trussed wind turbine tower is more convenient to lift, and requirements for using special equipments are decreased. The trussed wind turbine tower is beneficial to placement of the electrical equipment as being provided with the equipment room and is beneficial for maintenance personnel to go up and down the tower as being provided with the safety ladder stand.
Description
technical field [0001] The present invention relates to the field of wind power generation, more specifically, to a truss-type tower for a wind power generating set and a wind power generating set with the tower. Background technique [0002] Wind energy is a renewable energy with rich resources, clean and pollution-free. Wind power has become the fastest growing energy source in the world in recent years, and the wind power industry has also become a promising emerging industry. As an important part of the wind turbine, the tower not only supports the weight of the wind turbine, but also bears the wind pressure blowing on the wind turbine and the tower, as well as the dynamic load in the wind turbine. Its design level directly affects the performance of the wind turbine. work performance and reliability. [0003] The basic forms of towers are cylindrical towers and truss towers. Cylindrical towers are widely used in current wind turbines because of their beautiful appearan...
