| Abstract: | #3 and #4 units of Sanhe Power Plant have entered the stage of commercial operation.Through the power formula P=U2/R calculation,the panel of net safety evaluation experts conclude that action power of relay for non-electric protection export does not satisfy 5W power,which does not conform to the non-electric protection middle relay and related anti-accident requirements through a long cable trip circuit.This paper analyzes the causes of the various measures and eventually takes optimal scheme to avoid the... |
