Description

technical field [0001] The invention relates to the technical field of installation of rotor magnetic poles of hydraulic generators, in particular to a laser ranging system and method for rotor magnetic poles of hydraulic generators. Background technique [0002] Hydroelectric power generation is that the water flows radially into the water guide mechanism through the diversion of the volute, and the kinetic energy of the liquid is converted into static pressure energy, and then the static pressure energy is converted into the kinetic energy of the rotor through the blades. The runner is coupled with the generator rotor through the main shaft, drives the rotor magnetic pole to rotate and cuts the magnetic coil of the generator stator core, uses the principle of electromagnetic induction to generate high-voltage electricity in the generator coil, and then boosts the power through the transmission line through the transformer output to the grid. In order to ensure the safe op...

AI Technical Summary

Problems solved by technology

[0004] 1. When the unit is overhauled, the rotor poles are at a certain height from the ground. When measuring the distance of a rotor pole, it is necessary to go up and down the ladder frequently; the largest unit has 64 rotor poles, which wastes manpower and time, and also poses a safety hazard

[0005] 2. Since the installation position of the dial gauge is fixed, when the measurement position changes, the needle of the dial gauge needs to be taken out; frequently taken out and installed, the position of the needle is easy to change, which also has a certain impact on the measurement data

[0006] 3. The data of the dial gauge is pointer type, and the data is read manually; when the reading personnel and the viewing direction of the personnel change, there are differences in the read data

[0007] 4. The data read by humans is manually recorded, which is not conducive to archiving and storage, and is easily lost

Data comparison and analysis cannot be performed during follow-up maintenance
