Special rod for single circuit cable rotating overhead station

Abstract

The invention discloses a special rod for a single circuit cable rotating overhead station. The special rod comprises a rod body, a support platform, a seat type cable terminal and a seat type arrester, wherein the support platform is arranged above a cross arm on the top of the rod body, and consists of an X-shaped cross arm and a straight cross arm; the included angle of the X-shaped cross arm and the wall of the station is 45 degrees; the straight cross arm is positioned on the top of the X-shaped cross arm; the wall of the station is arranged on the inner side and the outer side in parallel; the seat type arrester is arranged on the cross arm positioned on the outer side; and the seat type cable terminal is arranged on the cross arm positioned on the inner side. According to the special rod, a cable is introduced out of the ground through the special rod tower structure, a cable head is connected with a GIS sleeve pipe by using a wire, the integral structure has the advantages of low height, small occupied space and low cost, simultaneously, the structure is simple, and the maintenance workload is reduced.

Description

【Technical field】 [0001] The invention relates to the technical field of high-voltage transmission lines, in particular to a special pole for single-circuit cable transfer overhead entry. 【Background technique】 [0002] With the continuous development of the economy and the continuous improvement of people's living standards, the city's electricity load is gradually increasing, and power cables are becoming more and more common in the construction of urban power grids. Affected by the timing of power grid planning, the construction time of substations and transmission lines is not uniform. Occurs, resulting in the inconsistency between the substation access method and the line construction method. [0003] In the existing transmission line project, when the power cable is transferred overhead to connect to the indoor substation, the conventional solution is to build a single-circuit or double-circuit cable terminal tower, and there are major problems: ①The conventional cable...

Problems solved by technology

[0003] In the existing transmission line project, when the power cable is transferred overhead to connect to the indoor substation, the conventional solution is to build a single-circuit or double-circuit cable terminal tower, and there are major problems: ①The conventional cable terminal Bearing, lightning arrester, insulation string, cable terminal head, wire, ground wire, etc., the structure is complex, the construction cost is high, and the construction is difficult; Not too close, the transmission space is large, and the later implementation will be greatly affected by the terrain; ③The whole tower is large in size and poor in overall aesthetics
