Abstract:Large and medium-sized turbine generator is widely used in digital current regulation of the anti-fuel liquid refrigerant(DEH System),high-pressure anti-fuel system(EH system) is an important part of the turbine DEH system,according to DL/T838 "power plant equipment maintenance guide" the electricity industry-standard requirements,the EH system is class A devices,and press the A-level maintenance projects on a regular basis for a major overhaul.EH system is more extensive and highly specialized,it has more device types.Overhaul can restore function,eliminate defects and ensure the unit’s safe and stable operation.
Keywords:EH system  overhaul  wearing  supervision
