Installation of Backwash Pipe for 500 kV Main Transformer Cooling System at Dachaoshan Power Station
Since 2022,during unit maintenance at Dachaoshan Power Station,it has been discovered that a large amount of freshwater shell vegetables have accumulated on the cooler filter screen of the transformer with the cooling water flow.It directly leads to the blockage of the cooler,almost losing cooling capacity,causing the temperature of the operating transformer to continue to rise and emit an alarm signal.To solve this problem,this article designs and installs the backwash sewage pipeline on the 500 kV main transformer cooler,so that the main transformer has the ability to flush and discharge the cooler during operation.
