Abstract

In this paper, one 220kV substation has been selected in each prefecture level company of State Grid Shandong, Hebei and Shanghai. A total of 26 different types of 220kV substations are selected. Nbm-550 electromagnetic field detector is used to detect the power frequency electromagnetic field intensity in different areas of the substation, and the linear hybrid model is used to compare the power frequency electromagnetic field detection results in different areas, to study the distribution of power frequency electromagnetic field in different areas of 220kV substation workplace. The test results show that the higher the voltage level is, the higher the power frequency electric field is in the same type of distribution device area with different voltage levels in 220kV substation; AIS area is higher than GIS area, indoor switchgear area, and overhead outgoing line is higher than cable outgoing line. GIS device, cable and switch cabinet have good shielding effect on power frequency electric field and power frequency magnetic field.
