| Abstract: | At present the development of various automation control systems as DCS,PLC and field-bus is more mature,however,since unpredictable surge nervy has a powerful destructive capability and furthermore,the time,location for its appearance can not be predicted and this has made the various automatic control systems place under its direct threat;the system failure has not only brought about a direct loss of hardwires,but also led to such dangers as production halt,misuse of equipment.This paper deals with the application of surge protector to the compressor control system in urea plant. |
