Pole collapse and tower collapse accidents of the high-voltage iron tower pose a significant threat to an electric power system, damage to electric power equipment and power supply interruption are caused, and safe operation of a power grid and normal safe power utilization of users are seriously influenced. The emergency repair tower is used for replacing an accident tower to quickly restore power supply when a power failure accident occurs due to pole falling, tower falling or tower footing landslide of a power transmission line of a power system. Particularly, the +/-800 kV ultrahigh-voltage direct-current transmission line has complex geological structure and variable meteorological conditions along the line, and is easy to have natural disasters such as freezing, typhoon, landslide, debris flow and the like.

The inventor of the application finds that the normally adopted emergency repair mode is to temporarily set up the iron tower for supporting the ultrahigh voltage transmission line at the position of the inverted tower, re-establish a new iron tower for the ultrahigh voltage transmission line, and then remove the temporarily set up iron tower for supporting the ultrahigh voltage transmission line, so as to complete emergency repair.

The column 10 of the emergency repair tower 100 of the present application is fixed to the ground, the corbel 20 is disposed along the first direction S1 and connected to the top end of the column 10, and the first suspension portion 21 on the corbel 20 can assume a first state parallel to the first direction S1 and a second state parallel to the central axis S3 of the column 10 under the traction of the overhead ground wire. When the first hanging part 21 is in the first state, the first hanging part 21 is parallel to the ground, and the emergency repair tower 100 can be used as a linear tower; when the first hanging portion 21 is in the second state, the first hanging portion 21 is perpendicular to the ground, and the emergency repair tower 100 can be used as a tension resistant tower.

Specifically, the overhead ground wire is also called a lightning conductor, and is a conducting wire directly communicated with the ground on a +/-800 kV extra-high voltage line. Due to the shielding of the overhead ground wire on the wire and the coupling effect between the wire and the overhead ground wire, the chance that thunder and lightning directly strikes the wire can be reduced. When the tower is struck by lightning, part of lightning current can be shunted through the overhead ground wire, so that the potential of the tower top is reduced, and the lightning resistance level is improved. When the circuit is rush-repaired, one end of the overhead ground wire is hung on the first hanging part 21, and the other end of the overhead ground wire is hung on the high-voltage iron tower with good function, so that the normal conduction of current can be ensured. The first suspension part 21 can assume a first state parallel to the first direction S1 and also a second state parallel to the central axis S3 of the upright post 10 under the traction of the overhead ground wire, so that the emergency repair tower 100 can be a tangent tower or a tension tower according to the actual emergency repair situation.

In some embodiments, the first suspension end 212 defines a first through hole 2121 for passing an overhead ground wire therethrough. Thus, one end of the overhead ground wire penetrates through the first through hole 2121 to be suspended at the first suspension end 212, and the rush-repair tower 100 and the high-voltage iron tower with good functions transmit current through the overhead ground wire, so that the current can be normally conducted.

The two ends of the upright post 10 are respectively provided with the support beams 20 along the two sides of the first direction S1, so that the balance of the emergency repair tower 100 can be kept, and the stability of power supply can be kept in severe weather. One end of each supporting beam 20, which is far away from the upright post 10, is hinged with a first suspension part 21, and the first suspension parts 21 on the two sides can be respectively connected with the iron tower with good function through an overhead ground wire, so that the normal conduction of current can be ensured.

In some embodiments, the emergency repair tower 100 further includes two corbel 20 corbel braces 22 located on both sides of the mast 10 along the first direction S1, each corbel 20 corbel brace 22 being connected to the mast 10 and to a corbel 20 on the same side. The corbel bracing 22 supports the corbel 20, so that the emergency repair tower 100 is more stable and can maintain the stability of power supply in severe weather.

In some embodiments, composite cross arms 30 are respectively connected to two sides of the upright post 10 between the top end of the upright post 10 and the bottom end of the upright post 10, and a second hanging portion 31 is provided at one end of each composite cross arm 30 far away from the upright post 10. The composite cross arms 30 are respectively connected to two sides of the position between the top end of the upright post 10 and the bottom end of the upright post 10, so that the emergency repair tower 100 can be kept balanced, and the stability of power-on can be kept in severe weather. One end of each composite cross arm 30, which is far away from the upright post 10, is hinged with a second suspension part 31, and the second suspension parts 31 on the two sides can be respectively connected with the iron tower with good function through an overhead conductor, so that the normal conduction of current can be ensured.

More specifically, the composite cross arm 30 is formed by connecting 6 sections of composite insulating sections through bolts, the single section is formed by filling 4 foam into an insulating tube and injecting a silicon rubber umbrella skirt on the outer surface, two ends of the insulating tube are provided with circular tube steel flanges, and the 4 insulating tubes are connected through aluminum alloy angle aluminum to form the composite insulating section. The composite cross arm 30 has a lattice structure, and is assembled in a sectional manner, thereby providing an advantage of easy handling and assembly. By applying the composite cross arm 30, the tower height can be reduced, the distance between lines can be compressed, the width of a corridor can be reduced, and the windage yaw gap value can be reduced. The middle section and the tail end of the composite cross arm 30, which are far away from the upright post 10 along the first direction S1, are respectively connected to the top end of the upright post 10 by adopting the insulating hanger rods 12, so that the composite cross arm 30 is prevented from falling due to the action of gravity, and the normal operation of the emergency repair tower 100 is maintained.

In some embodiments, the second suspension portion 31 includes a second hinged end 311 hinged to the compound cross arm 30, and a second suspension end 312 connected to a side of the second hinged end 311 remote from the compound cross arm 30.

The second hanging portion 31 may assume a first state parallel to the first direction S1 and may also assume a second state parallel to the central axis S3 of the upright 10, so that the emergency repair tower 100 may be a tangent tower or a tension tower depending on the actual emergency repair situation.

In some embodiments, the second hanging end 312 defines a second through hole 3121 for the overhead conductor to pass through. So, the second through-hole 3121 is worn to locate by the one end of air wire and is hung end 312, and the other end of air wire hangs in the high-voltage iron tower of functional well, and consequently, air wire transmits current through air wire between rush-repair tower 100 and the high-voltage iron tower of functional well, can guarantee that the electric current can normally conduct.

And is beneficial to keeping the emergency repair tower 100 stable.

In some embodiments, a pull wire 40 is connected to the top end of the upright 10, and the side of the pull wire 40 away from the top end of the upright 10 is connected to a ground anchor 41. The ground anchor 41 is connected to the ground, so that the emergency repair tower 100 can be stably maintained under the action of the pull line 40 and the ground anchor 41

Specifically, the outer surface of the stay wire 40 is wrapped by the insulating layer 42, and because the stay wire 40 is made of metal, if the distance between the wire and the stay wire 40 does not satisfy the charged gap, the wire can discharge onto the stay wire 40, and the insulating protective layer is adopted at the upper end of the stay wire 40, so that the discharge condition can be avoided, and the safety of line emergency repair is ensured.

The rush-repair tower 100 is designed by adopting the single upright post 10 type upright post 10, can be suitable for various complex terrains such as mountainous regions, hills and the like, and has the advantage of small occupied area, and the upright post 10 and the lattice type composite cross arm 30 are combined to realize the advantages of light weight and convenient installation. The bottom end of the upright post 10 is hinged with the base 11 fixed on the bottom surface, so that the upright post 10 can stand up conveniently and the stress in the hinge part 112 can be eliminated. The supporting beam 20 and the upright post 10 are supported by the supporting beam 20 and the supporting beam diagonal brace 22, so that the emergency repair tower 100 is more stable, the top end of the upright post 10 is connected to one end of the stay wire 40, and the other end of the stay wire 40 is connected with the ground through the ground anchor 41, so that the emergency repair tower 100 can resist strong wind. The insulating layer 42 is arranged on the stay wire 40, so that the condition of discharging can be avoided, and the safety of line emergency repair is ensured. The side of each corbel 20, which is far away from the upright 10, is hinged with a first suspension part 21, which can present a first state parallel to the first direction S1 and can also present a second state parallel to the central axis S3 of the upright 10, and the side of the composite cross arm 30, which is far away from the upright 10, is hinged with a second suspension part 31, which can present a first state parallel to the first direction S1 and can also present a second state parallel to the central axis S3 of the upright 10. When the first hanging portion 21 and the second hanging portion 31 are both relatively perpendicular to the ground, the emergency repair tower 100 is a straight tower, and when the first hanging portion 21 and the second hanging portion 31 are both relatively parallel to the ground, the emergency repair tower 100 is a straight tower.
