Abstract: There has been a 1000 kV ultra-high-voltage (UHV) AC
transmission line running in China, but the related papers introducing the
approach path of the helicopter live-line work platform (HLLWP) are still not
presented. The model of the HLLWP approaching the transmission lines were
established in this paper, based on the real parameters of helicopter MD500
and 1000 kV UHV AC transmission lines. Through calculating electrostatic
field with the finite element method, the results of the electric field were
obtained when the HLLWP was at different locations nearby a certain phase
and approaching different phases. The surface electric fields on the HLLWP
and operator's conductive clothing at different locations were analyzed and
then the optimal approaching paths of different phases based on the
consideration of the HLLWP and operator's safety were proposed to provide
suggestions for the operations of the HLLWP. In the end, the experimental
data was compared with the numerical result to prove the reliability of this
method.
