Background
Most of the direct current lines constructed at present adopt a bipolar earth system, grounding electrodes are respectively arranged at converter stations at two ends of a power transmission line, the power transmission line transmits direct current through positive and negative electrode leads, and unbalanced current between the two electrodes flows back through the earth between the grounding electrodes at the two ends. The grounding electrode circuit is provided with a left side wire, a right side wire and a ground wire. The operating voltage of the grounding electrode line conductor is low, generally tens of kilovolts, one end of the grounding electrode line conductor is connected with a grounding point of the converter station, and the other end of the grounding electrode line conductor is connected with a grounding electrode.
Therefore, the direct current line tower is generally erected by the same tower of the earth electrode earth wire and the earth electrode lead, the earth electrode earth wire is erected above the earth electrode lead, the fall height between the earth electrode earth wire layer and the earth electrode lead layer is 3-5m, the height of the iron tower needs to be set higher (see figure 2), and the engineering investment amount is larger.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that, overcome prior art not enough, provide a tower head height little, the investment is low lead, the direct current earthing pole circuit tangent tower that the ground wire merges.
The technical scheme that the utility model solves the technical problem adopts is that, lead, the direct current earthing pole circuit tangent tower that the ground wire combines, including tower head and body, the whole tangent tower is "T" style of calligraphy structure, and the tower head is "one" style of calligraphy structure, and the both sides of tower head are equipped with left side wire hanging point and right side wire hanging point respectively, the hanging point punishment of left side earthing pole wire hanging point and right side earthing pole wire hanging point is respectively through lightning protection, anti-icing sudden strain of a muscle insulator connection earthing pole wire;
the grounding electrode leads are suspended on the left side and the right side of the tower head, and the grounding electrode leads are used as normal leads under normal conditions; the grounding electrode lead is used as a ground wire when the tangent tower is struck by lightning to discharge the lightning.
Further, the tower head and the tower body are made of angle steel.
Utilize the utility model discloses the tangent tower of construction can merge the wire and the ground wire of earthing pole circuit tangent tower, reduces more than the high 15m of iron tower, has reduced earthing pole circuit engineering investment.

fig. 2 is a schematic structural diagram of a conventional earth electrode line tangent tower.
In the figure: 1. the tower comprises a tower head, 1-1 parts of a left side wire hanging point, 1-2 parts of a right side wire hanging point, 2 parts of a lightning protection and anti-icing flashover insulator, 3 parts of a grounding electrode wire and 4 parts of a tower body.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples.
Referring to the attached drawing 1, the tower comprises a tower head 1 and a tower body 4, the whole straight line tower of the grounding electrode circuit is of a T-shaped structure, the tower head 1 is of a I-shaped structure, and two sides of the tower head 1 are respectively provided with a left wire hanging point 1-1 and a right wire hanging point 1-2.
The hanging points of the left grounding electrode wire hanging point 1-1 and the right grounding electrode wire hanging point 1-2 are respectively connected with a grounding electrode wire 3 through lightning protection and anti-icing flashover insulators 2, the grounding electrode wires 3 are suspended on the left side and the right side of the tower head 1, and the grounding electrode wires 3 have the function of a ground wire.
Under the normal operating condition, the lightning protection and anti-icing flashover insulator 2 is in an insulation state and is in a conduction state after suffering lightning overvoltage.
The grounding electrode wires 3 are suspended at the left side and the right side of the tower and are in an insulated state with the tower body 4 under the normal operation condition; when thunderbolt wire, lightning protection, anti-icing dodge insulator 2 is punctured, is the on-state, and lightning current is released to the ground through body of the tower 4 and earthing device, and earthing pole wire 3 uses as the ground wire, and lightning current releases the back of accomplishing, and lightning protection, anti-icing dodge insulator 2 resume insulating state, and the normal operating condition is resumed to the circuit, and earthing pole wire 3 uses as normal wire.
The tower head 1 and the tower body 4 are made of angle steel.
The utility model discloses an adopt lightning protection, anti-icing sudden strain of a muscle insulator to merge the wire and the ground wire of earthing pole circuit, can effectual compression iron tower height 3-5m, reduced earthing pole circuit engineering investment amount by a wide margin.
Various modifications and variations of the present invention may be made by those skilled in the art, and they are still within the scope of the present invention, provided they are within the scope of the claims and their equivalents.
What is not described in detail in the specification is prior art that is well known to those skilled in the art.
