Although the axial length L of the beam members 12C and 13C of Nos. 2 and 13 can be reduced, the construction of the electric station is performed because the transmission line anchoring iron structures 12 and 13 are doubled. In addition to increasing the cost, the transmission lines 4 and 5 were enlarged in size, increasing the installation area of the electric station. On the other hand, in the substation disclosed in Japanese Patent Laid-Open No. Sho 55-68805, in order to reduce the size in the direction in which the power transmission line is drawn, the beam members, which are the constituent elements of the power transmission line anchorage structure, are arranged in two stages, upper and lower. It has been proposed to make the number of anchorage structures for transmission lines one by configuring the above.

型化することができなかった。However, even in the latter conventional transmission line anchorage structure for a transmission line, the transmission line is supported by a beam member which is a constituent element of the transmission line anchorage structure via an insulator. Therefore, the aerial overhead line with one end connected to the power transmission line supported by the upper beam member is lowered to the lower part while considering the insulation between the lower beam member and connected to the corresponding air bushing of the electric device. Although it is necessary to reduce the size in the direction of the transmission line, if a sufficient insulation distance is secured between the upper beam member and the lower beam member, the height will be considerably increased, and eventually the transmission line It was not possible to reduce the size of the drawn steel structure.

That is, in the conventional transmission line anchorage structure, if it is also explained with reference to FIG. 1, since another beam member is formed below the one beam member 16C, the beam member 16C located in the upper part is formed. In the aerial overhead line 9V connected to the medium-phase power transmission line 4V that is retained via the detention insulator 18V, it is necessary to consider the aerial insulation distance with the beam member located in the lower part, and therefore The height of the beam member 16C to be located had to be increased, and the entire transmission line anchorage structure was raised. Moreover, in the present embodiment, one ends of the anchors 8U, 8W are fixed to the columnar members 16A, 16B to support the power transmission lines 4U, 4W,
Since the beam member located in the lower portion of the related art is omitted, the structure of the transmission line anchoring steel structure 16 can be simplified, and the interval L between the columnar members 16A and 16B can be made narrower and smaller than the conventional one. be able to. At this time, if the overhead wire 9V connected to the power transmission line 4V passes between the power transmission lines 4U and 4W, a predetermined air insulation distance must be secured between the power overhead line 9V and the power transmission lines 4U and 4W. Therefore, the transmission line 4
Distance between U and 4W and distance L between columnar members 16A and 16B
Will have to be increased. However, in this embodiment, the mid-phase air bushing 1V is arranged on the side opposite to the transmission line of the transmission line anchoring steel structure 16, and the support arm 17V is provided on the side opposite to the transmission line of the beam member 16C. Power line 4
Since the middle portion of the aerial overhead wire 9V connected to V is supported by the retractor insulator 18V provided on the support arm 17V, the aerial overhead wire 9V can be kept away from the opposing portion of the power transmission lines 4U and 4W. If the insulation distance between the overhead cable 9V and the columnar members 16A, 16B is secured, the overhead cable 9V can be used as the power transmission lines 4U, 4B.
The distance between the power transmission lines 4U and 4W and the distance L between the columnar members 16A and 16B can be reduced as compared with the case of passing between W.
