Description

Technical Field

[0001] The utility model relates to the technical field of generator set radiator control, and more specifically, to a radiator control system for a gas generator set. Background Art

[0002] The containerized gas generator set has a high degree of modularization. It uses a gas engine as the prime mover to drive the generator to rotate. After the generator speed is consistent with the grid frequency, the high-voltage switch is closed to achieve grid-connected power generation. During the operation of the engine, the fuel gas entering the equipment and the engine cylinder block need to be cooled respectively. The cooling is achieved through two cooling circulation devices. The coolant passes through the engine (intercooler and cylinder sleeve) → pipeline → water pump → radiator → engine, and the coolant with high-temperature gas and the heat of the engine body is cooled by the radiator.

[0003] Most of the current radiator fan motors of gas generator sets use industrial frequency motors. One air switch is configured for two motors to control the start and stop of the fan motors. Manually control the number of started fan motors to prevent the water temperature at the engine inlet from being too low or too high. However, controlling the heat dissipation of the radiator by manually starting and stopping the number of fan motors has relatively low efficiency, and the number of started fan motors cannot be adjusted in real time according to the temperature. The operating temperature of the engine cylinder block and the intake temperature of the engine cannot be dynamically maintained within the specified range, which is not conducive to the long-term operation of the equipment. Moreover, when the fan motor coil burns out, it cannot be detected in time, affecting the use effect. Therefore, a radiator control system for a gas generator set is proposed.
