Hazard identification and preventive measures of grounding system
Yin De-shan · Journal of Safety Science and Technology · 2011
Grounding,as a engineering technology of reducing disaster,is usually used in the site of explosive atmospheres and fire hazard,substation,power station,and some big buildings.The application of grounding can avoid equipment trouble and hurt for overvoltage and electric shock.A well grounding connection can reduce industrial accident.But because it is an interdisciplinary subject,the effective use of it need a large amount of knowledge in many professional fields,a lot of factor bringing bad influence on the system are usually neglected by the user in the course of production,the error could cause equipment failure or injury.Therefore,hazard identification of grounding system is important to keep industry output safe.In this paper various kinds of grounding were regaded as a whole grounding system.The hazard identifiation in lightning protective ground,protective ground,working ground and static protective ground were conducted with system safety analysis.According to the result of hazard identification,the preventive measures in the respect of safety management and safety technology were proposed.At lase,some important problems influencing development of grounding engineering technology were put forward,in order to support the development of the subject on grounding engineering and technology,and service the production.
