Supply Enterprise Production Safety Hazard Identification Study

The security question of the power supply enterprise is an important problem, It is concerning the national economy and the people's livelihood, how find potential safety hazard , take measures as soon as possible accurate in time to prevent hidden danger from turn into the accident, it is electric experts at home and abroad , scholar and enterprise's administrator that have been studying the subject probed into emphatically all the time . The safe system engineering uses the network analysis theory to solve the safe problem, has offered more intact qualitative, quantitative dangerous discernment method, through analysing in advance scientifically, find out weak link and main hidden danger existing in the system, have solved distinguishing and safety evaluation problem of the accident potential of power supply enterprise well.Dangerous discernment method of the system is divided into qualitative discernment and quantitative discernment A basic one and commonly used method including safe check table, analysing dangerously in advance, event tree analysis and fault tree analysis. The fault tree can not only suitable for qualitative analysis but also carry on quantitative analysis , concise , vivid , accurate , practical, it is a kind of generally acknowledged analytical method both at home and abroad. This page article has done the key introduction to this kind of method.Electric system reform, separate the factory and network, make the power supply enterprise face the new security problem. Pass the statistical analysis of accident happenning to the power supply enterprise, three major types of body , electric wire netting , equipment that divide the accident, adopt the dangerous discernment method to distinguish and appraise it. The equipment accidents of voltage transformer and the bodily injury accident of fall in the altitude that this text are done for the example, adopt the fault tree to analyse it determining the nature, has looked for the hidden danger, through further quantitative analysis, analyse various kinds of basic incident (hidden danger) to happen of size of influence of incident (accident), thus found out the main fact, reason once of the accident of happenning , has offered the scientific basis for taking the corresponding measure. Dangerous discernment method of the system diagnose dangerous exceed the forebay, predictably, appraise out thedangerous existence degree more accurately, prevent the accident scientifically, have guaranteed the safe and reliable operation of electric wire netting.
