Abstract:
Introduce mainly the treatment of DCS system of ABS plant after lightning stroke. Analyze thunder and lightning existing possibility from geography condition of plant. From the aspects earthed pole of DCS system,the mode of ground connection in cabinet of system,the connection cable to enter indoor existing unreasonable, the lightning protection facility imperfection and so on, to analyze the reason this time for suffered the lightening stroke. And propose corresponding changing some measures aimed at above imperfect condition.[著者文摘]
