The invention provides a vibration switch debugging method and device. A vibration switch can be accurately debugged according to a preset acceleration limit value. The method comprises the steps that external force is applied to a swing rod in the vibration switch for simulation triggering, and the bending radius of the swing rod is determined; a weight is hung on the swing rod, simulation triggering is carried out by adjusting the weight of the weight and the hanging position, and the minimum triggering torque of the vibration switch is determined; and according to the preset acceleration limit value and the minimum trigger torque, the installation weight and the installation height corresponding to the preset acceleration limit value are calculated and determined, and the weight is debugged and installed according to the installation height. The device comprises a first simulation trigger module, a bending radius calculation module, a second simulation trigger module, a trigger torque calculation module, a debugging calculation module and a debugging installation module.
Description
technical field [0001] The present disclosure relates to the technical field of wind power generation, in particular to a vibration switch debugging method and device. Background technique [0002] In recent years, in order to increase the power generation of wind turbines, the capacity of wind turbines has increased. As the blades have become longer and the towers have become higher and higher, the low-frequency shaking of wind turbines and towers has caused the accidents of wind turbines to collapse. More and more, it is necessary to monitor the swing range of the tower. [0003] At present, the wind turbine generator sets are equipped with vibration switches to detect the low-frequency shaking of the wind turbine generator set. When the tower swings the most, the acceleration of the weight of the vibration switch is the largest. If the acceleration exceeds the limit, the vibration switch will activate and trigger the safety chain to stop the unit in time. Safety. In pra...
