Description

technical field [0001] The invention relates to the technical field of water wheel group monitoring, in particular to a swing detection device for a water wheel generator set. Background technique [0002] A hydroelectric generator is a generator that uses a water turbine as the prime mover to convert water energy into electrical energy. When the water flows through the water turbine, the water energy is converted into mechanical energy, and the rotating shaft of the water turbine drives the rotor of the generator, which converts the mechanical energy into electrical energy and outputs it. It is the main power equipment for generating electric energy in hydropower stations. [0003] When the hydroelectric generating set is working, since the rotating shaft of the water wheel is not perpendicular to the axis of the spine, the unit and the rotating shaft of the water wheel will swing. When the rotating parts of the unit swing greatly during operation, the unbalanced force on...

AI Technical Summary

Problems solved by technology

When the rotating parts of the unit swing greatly during operation, the unbalanced force on the unit will also increase, which will aggravate the vibration of the unit and affect the stable operation of the unit

[0004] At present, the planned maintenance system is mostly implemented for the maintenance of hydroelectric generating units, and the unit is not overhauled according to the actual state of the equipment, resulting in a waste of manpower and material resources, and its monitoring unit is vulnerable to strong electromagnetic interference and strong vibration environment at the hydro turbine monitoring site.
