Background
The generator stator cooling water system is used for cooling a generator stator winding and a high-voltage bushing on the outgoing line side. The system is a closed circulation system. The water quality is generally desalted water and comes from a chemical water supply system. Before entering a closed circulating cooling water system of the generator, cooling water is firstly deionized by the deionized device for ion exchange, then is stored in the fixed cooling water tank, and then is injected into the stator winding by the stator cooling water pump. In addition, the generator is also provided with a hydrogen cooling system, when hydrogen leakage occurs, hydrogen is easy to leak into the fixed cold water and then is discharged by the fixed cold water, and the conventional common method for preventing and controlling the hydrogen leakage of the generator system of the large-scale generator set is mainly that a hydrogen leakage detection device is arranged in a relevant possible leakage area, and the problem of the hydrogen leakage can be found in time by the alarm of a detector; the hydrogen leakage alarm device can find and confirm the hydrogen leakage point, but cannot accurately confirm the leakage amount; although the leakage amount can be preliminarily determined by measuring the concentration through the hydrogen leakage alarm device, accurate data cannot be provided for the safe operation of the unit, and whether the leakage amount is within the normal operation allowable range of the unit or not cannot be determined.
