Embodiment Construction
[0017] The present invention will be further described below in conjunction with the accompanying drawings.
[0018] refer to Figure 1 ~ Figure 3 , a zero-angle doubly-fed wind turbine full-power machine-to-drag test bench, including:
[0019] The connection type of test unit 1 adopts 2 test units of the same model, arranged face to face, and connected through the telescopic universal coupling 2, because the test unit 1 is only connected through the coupling 2, the main shaft of the test unit and the universal coupling The angle between the devices is 0°, the transmission chain is simple, and the transmission efficiency is as high as 98%. Without adding additional power to the test unit, the full-power mutual drag of the same type of unit can be realized.
[0020] The foundation, the foundation forming process includes planting bars 3, platform steel frame 5 anchoring, arrangement of reinforcement mesh 4 and pouring of concrete 6. Among them, planting bar 3 adopts three-gra...

The invention relates to a post-anchored steel-concrete type zero-included-angle full-power complete machine pair dragging test bed suitable for doubly-fed type wind turbine generator sets. The test bed comprises a foundation, fixing parts of the test generator sets and a test bed body, and a connector of the test generator sets; the foundation is positioned on an original factory floor and is a power mechanical test foundation formed by pouring concrete; two platform steel frames arranged in the opposite directions are arranged on the foundation; the test bed body performs tests without disassembling conveying supports; the fixing parts of the test generator sets and the test bed body adopt combination of pressing blocks and bolts, and base plates of the conveying supports of the test generator sets are connected to the platform steel frames through the combination of the pressing blocks and the bolts; the connector of the test generator sets adopts a telescopic universal coupling; and the included angles between main shafts of the two test generator sets and the universal coupling is 0 degree. The post-anchored steel-concrete type zero-included-angle full-power complete machine pair dragging test bed suitable for the doubly-fed type wind turbine generator sets has the advantages of being high in universality, low in vibration, low in cost and easy to install and maintain.
Description
technical field [0001] The invention relates to the technical field of wind power generation, in particular to a post-anchor steel-concrete type zero-angle double-fed wind turbine complete machine towing test bench. Background technique [0002] With the implementation of GB / T21407-2015 "Double-fed Variable Speed Constant Frequency Wind Turbine Set" and GB / T 31518-2015 "Direct Drive Permanent Magnet Wind Turbine Set" standards, the factory test inspection methods and items of wind turbine sets have been clarified And implementation, the drag test, as the main content of the factory test, has been highlighted in the factory and verification of wind turbines. The whole machine drag test can not only witness the performance of the wind turbine and verify some important indicators, but more importantly, it can reduce the subsequent on-site commissioning cycle, reduce the failure rate of the product, and reduce the cost of on-site commissioning and maintenance. It provides a s...
