Identification,precontrol and management of danger source in the removal engineering of large transformer
Lei Ying-qi · Journal of North China Electric Power University · 2010
Recently,in nativeland,the safety problem in engineering costruction and industrial production are seriously,accidents are freguently happened.The removal of large transformer of underoperation 500kV substation,because of large amount of construction machine,narrow site,more working condition complexity,especially the removal operation is always under strong electro-magnetic field,the safety problem is more protuding.In order to guarantee working substation operation safety and make removed transformer reusable,during the process,the danger source identification supernormal technical means and precontrol scheme were intoduced.Practice indicats that expect target is achieved and the removal safety is obtained.
