Background
In order to ensure the safety and reliability of the generator in operation, according to the requirements of the technical specification of installation of the water turbine generator set GB8564-2003, the pressure of the carbon brush on the collector ring of the newly installed or repaired generator is basically uniform, and the pressure of the carbon brush on the collector ring of the generator is ensured to be basically uniform because the pressure of the carbon brush on the collector ring of the generator is given by the elastic force of the compression spring, and actually, the elastic force of the compression spring of each carbon brush around each collector ring is required to be uniform (within a certain range). The generator need screen the inspection to each pressure spring elasticity that is ready for to use when overhauing, and the tradition way is artifical inspection, mainly relies on the inspection of feeling, and for guaranteeing inspection quality, the pressure spring that same unit used often needs 3 different people to respectively carry out 1, carries out 3 inspection totally. The group personnel carry out statistical analysis on the pressure manual screening and checking time of the compression springs of the machine sets 1, 3 and 5 during the machine set maintenance period from 2016 (11 months) to 2017 (5 months), the number of the compression springs used by one machine set in the factory is 72, and the average time consumption for the pressure manual screening and checking of the compression springs of each machine set is found to be 2.06. The maintenance period of the generator is fixed, the time is short, the whole unit maintenance process is inspected, the average consumed time of the unit compression spring pressure manual screening and checking is considered to be too large, the main reason is that the screening is carried out by depending on manual feeling, the screening effect and efficiency mainly depend on the personal ability and experience level, the consumed time and the labor are low, and the accuracy is low, so that the development of the screening and checking equipment capable of improving the elastic force screening and checking efficiency and the accuracy of the generator carbon brush compression spring is very important.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a generator carbon brush pressure spring elasticity testing arrangement.
