Abstract


In the west of China in high altitude area construction extra and ultra high voltage line facing the corona problems more serious than plain region, the different elevation wire a halo characteristics to guide the extra and ultra high voltage circuit design has important significance. Using ultraviolet imaging detection technology, research the traverse the halo voltage method, and application of this method in four different height place, the corona cage conductor on the up dizzy characteristic test research. Test for the four types of wire respectively in dry and be caught in the rain under the condition of communication the halo voltage value, according to the test data obtained, the current the halo voltage altitude correction methods are verified the applicability, and put forward the suitable for high altitude areas in west China a halo voltage altitude correction formula, the test result can guide our high altitude area transmission engineering design and operation.
