The invention discloses a method for operating a generator in a ship dock. The method comprises the following steps that a seawater inlet of a fresh water cooler is connected with a water inlet drainage pipe, a seawater outlet of the fresh water cooler is connected with a water outlet drainage pipe, and a fresh water inlet and a fresh water outlet of the fresh water cooler are correspondingly connected with a cooling water inlet and a cooling water outlet of the generator; fire-fighting water on the shore is conveyed to the seawater inlet of the fresh water cooler through the water inlet drainpipe; and high-temperature cooling fresh water formed in the operation process of the generator flows out of the cooling water outlet of the generator and flows into the fresh water inlet of the fresh water cooler, is cooled by low-temperature fire-fighting water in the fresh water cooler, flows out from the fresh water outlet of the fresh water cooler and then flows into the generator from the cooling water inlet to cyclically cool the generator. According to the method for operating the generator in the ship dock, the main generator on the ship can normally operate in the dock, so that power is supplied to equipment with the rated voltage of 6600V, and the ship equipment can normally perform debugging operation.

    本发明公开了一种船舶船坞内发电机运转的方法,该方法通过在淡水冷却器的海水进口连接进水排管,在淡水冷却器的海水出口连接出水排管,并将淡水冷却器的淡水进、出口分别与发电机的冷却水进、出口相连;通过进水排管将岸上的消防水输送至淡水冷却器的海水进口,发电机运行过程中形成的温度较高的冷却淡水从其冷却水出口流出并流入淡水冷却器的淡水进口,经过淡水冷却器中的温度较低的消防水冷却后,从淡水冷却器的淡水出口流出,再从冷却水进口流入发电机对发电机进行循环冷却。本发明使船上的主发电机能够在坞内正常运转,从而为额定电压为6600V的设备供电,使该类船舶设备能够正常进行调试作业。
