沿海地区500kV变电站电磁环境分布与防护措施
Electromagnetic Environment Distribution of 500 kV Substations in Coastal Areas and Protective Measures
摘要
Abstract
In allusion to the situation of increasing high voltage substations in one coastal city,this paper studies distribution characteristics of working frequency electromagnetic filed environment in 500 kV substations in this area.On the basis of measuring working frequency electric field intensity and magnetic field intensity in each region of 500 kV outdoor substations in one coastal city and hybrid GIS substations as well as around equipment,it counts,concludes and analyzes distribution characteristics of electromagnetic environment in high voltage substations and critical control zones for occupational exposure,which have been verified by simulating analysis.Results indicate that integrated working frequency electromagnetic environment in 500 kV substations in this area is preferable,regions with larger electric field intensity are mainly in 500 kV switchyards,while regions with excessive working frequency magnetic filed are electric reactor zones and critical exposure positions concentrate in outside phase of bus,switch devices,voltage transformers,current transformers,and so on.In aspect of occupational safety,it also presents relevant protective measures such as increasing protection distance,controlling touch time and wearing shielding clothes.关键词
