摘要:
The distributions and features of power frequency electromagnetic fields within 500kV substations in Chongqing area are studied. In view of gradually increasing of 500kV substations in Chongqing area, the impacts of power frequency electromagnetic environment within 500kV substations on professional exposure are researched. For this reason, the power frequency electric and magnetic fields in the regions within 500kV substations and in the locations around the power equipments are carefully measured and the measured results are generalized and summarized, and the special regions with higher electric and magnetic field intensity are deeply researched. According to the measured distributions of electromagnetic fields and from the standpoint of occupational safety, the matters needing attention for safety production within 500kV substations are pointed out. Several rationalization proposals concerning safety management of 500kV substations, reasonable disposition and design for new 500kV substations to be constructed and the selection of new substation equipments are suggested.
