Ye Li · Mechanical & Electrical Engineering Magazine · 2006
The composition of the main water-spraying extinguishing system for the main transformer was simply introduced.In order to innovate the water spraying extinguishing system and to realize automaticeally extinguishing fire,periodically(inspecting) it,the S7-200 PLC for the main transformer control system were adopted,the system brief block diagram and PLC procedures to control were introduced.Practical application show that the feasibility of innovation is certificated.
