Generator collector ring inlet air temperature
According to the different insulation grades of diesel generators, the temperature rise requirements are different. . High-capacity collectors are cooled by forced convection, typically with ventilating air pumped by shaft-driven fans. Proper ventilation is important for preventing overheating, which can result from (1) blocked passages in intake or exit ducts, (2) plugged ventilation holes in the collector rings. . Cooling systems are designed to provide adequate cooling for full load operation at a specified ambient air temperature typically between 40C° (104F°) and 50C° (122F°). It is important to ensure that the ambient air capability is adequate for the site as operating above the rated ambient air. . Air cooled unit draws cooling air from different ends of the unit to cool the system, dependent upon the units cooling system design. Check with the generator's manufacturer to determine the optimal cooling method for the system. Factors such as climate and direction of prevailing winds must be. . There are three types of reasons for heating faults of brushes and collector rings.
