<p><P>PROBLEM TO BE SOLVED: To provide a phase exchanging work method of overhead line good in workability and economy in which electric safety separation can be secured sufficiently while ensuring charging of one line without requiring temporary construction such as a supporting pole or a special space. <P>SOLUTION: In a phase exchanging work method of overhead line including a section for charging one line using an arbitrary three-phase out of one side overhead line including three-phase as one line and the other side overhead line including three-phase as one line wired in three stages of upper phases 11, 21, intermediate phases 12, 22, and lower phases 13, 23 to one side arm 2 and the other side arm 3 of a steel tower 1, there are a region 6 for exchanging the phase of overhead line and a region 7 for resetting the phase of overhead line. In the phase exchange region 6 and the phase reset region 7, a step for connecting the lower phase and the intermediate phase of the one side overhead line, a step for connecting the intermediate phase and the upper phase of the one side overhead line, and a step for connecting the upper phase of the one side overhead line and the upper phase of the other side overhead line are performed. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
