    Abstract
  • To control the risk of disaster that may be caused by ice-coated power line, a novel de-icing method by applying linear shaped explosive blast has been proposed in the past decade. To investigate the mechanism and the key technology, blast tests on short ice-coated power line are performed as well as corresponding LS-DYNA simulations. The effects of blast parameters on de-icing efficiency are also discussed. Results show that, ice on the blast side immediately crush while through-wall cracks appear in the other side ice which then fractures or falls from the line. The blast energy rapidly attenuates from the weakly constrained side of ice when the detonation cord is placed outside of the ice. As a consequence, in order to de-ice with high efficiency, the gap between conductor and detonation cord should be optimized according to estimation ice coating thickness to ensure that the detonation cord is located within the ice coating.
