Description

Technical Field

[0001] The utility model relates to a generator device, in particular to an electric control cabinet body structure for a generator cooler. Background Art

[0002] At present, the wind power equipment market is highly competitive. In order to gain a competitive advantage, various equipment manufacturers are competing to develop higher-power doubly fed and semi-direct drive models (typically 10MW and above). Since the use of direct air cooling can effectively reduce the temperature rise of the generator and increase a certain capacity, it is currently widely used by various wind power mainframe manufacturers. A typical direct-cooled generator cooler mainly includes a cabinet, a cooling fan unit, an air duct, an air valve and a filter. The typical welded cabinet structure is mainly made of several thicker (typically 3-6mm thick) steel plates through cutting, sheet metal forming, assembly, welding, shaping, painting and other processes. It uses a lot of materials, has poor processability, and requires more labor hours; the cabinet is a load-bearing structure used to install cooling fan units, filters, etc. At this time, it is necessary to design a disassembly structure on the welded cabinet, which increases the complexity of the cooler product, especially the cabinet structure, and the processability becomes worse.

[0009] By means of the above scheme, the utility model has at least the following advantages:

[0010] The technical solution of the present application reduces the cost of existing direct-cooling coolers and increases production. At the same time, combined with the characteristics of the plug-in cabinet structure, it ultimately achieves a cabinet structure with good processability and low cost, which can be better used with higher-power doubly-fed and semi-direct-drive models.
