| Abstract: | Aiming at the all cooler shutdown accident of forced oil circulation and air cooling 220 kVmain transformer,analyzes the accident causes,puts forward improvement measure to raise thesetting values of working voltage and adjusting voltage supervisory relay for cooler. The applicationresult shows that the measure stabilizes the working voltage of the cooler,eliminates the hiddentrouble leading to the cooler shutdown,ensures the safe and reliable operation of the maintransformer. |
