Abstract
The utility model relates to a suspension type circuit structure based on high tension power transmission tower is provided with the bearing force line between each power transmission tower, and power transmission tower utilizes to draw down fixture and causes the additional cable to required height, and the additional cable passes through the connecting piece to be connected in the bearing force line. The bearing wire is a lightning conductor. The utility model discloses solve the new open of difficult area weak current circuit and communication line and open up the passageway problem, solve simultaneously and install the energy supply problem of the power consumption equipment on steel pylons or circuit.
Description
Technical Field
The utility model relates to an improvement of high-tension transmission iron tower structure.
Background
The weak current line or communication line is erected, and at present, overhead support is generally adopted, a new path channel is opened up, and the erection difficulty and the cost are high for areas with limited paths and complex bottom surface conditions. In addition, the existing energy consumption equipment installed on the overhead transmission line basically obtains power supply energy for wind-light energy and electromagnetic induction in a functional mode, is greatly influenced by external conditions, and is low in electric energy output efficiency and power and poor in stability.
SUMMERY OF THE UTILITY MODEL
The utility model solves the technical problem that: the problem of newly opening a channel for weak current lines and communication lines in difficult areas is solved, and the problem of energy supply of energy consumption equipment installed on a power transmission iron tower or lines is solved.
The utility model discloses the technical means who adopts do: a suspension type line structure based on high-voltage power transmission towers is characterized in that a bearing line is arranged between each power transmission tower, the power transmission towers utilize down-leading fixtures to lead additional cables to a required height, and the additional cables are connected to the bearing line through connecting pieces.
The bearing wire is a lightning conductor.
The additional cable is a weak current wire, an insulating device is arranged between the additional cable and the power transmission iron tower, and an insulating device is also arranged between the additional cable and the bearing wire.
The additional cable is a communication line, an insulating device is not arranged between the additional cable and the power transmission tower, and an insulating device is not arranged between the additional cable and the bearing line.
The utility model has the advantages that: the utility model discloses hang the weak electric wire or the communication line of additional cable on the load line, can realize weak electric wire, communication line and high tension transmission line shared channel, avoid opening up new path passageway, effectively improve economic benefits.
Moreover, the weak current line erected on the power transmission line can also have the function of energy consumption equipment on a power transmission line iron tower or the line, the power supply performance is more stable and reliable, and the variety of the energy consumption equipment on the iron tower can be effectively expanded.

Detailed Description
As shown in fig. 1, the utility model relates to a suspension type line structure based on high tension power transmission tower is provided with bearing force line 2 between each transmission tower 1, and bearing force line 2 here can be the better steel strand wires of the tension sag characteristic of establishing in addition, also can be the direct lightning conductor that uses. The point is that the power transmission tower 1 uses the down-draw fixture 3 to draw the additional cable 4 to the required height, and fig. 3A and 3B are two common down-draw fixture structures, which are respectively used for two main components of the existing power transmission tower, namely an angle steel type and a steel tube type. Fig. 3C is a schematic perspective view of the connection with the angle iron. As shown in fig. 2, from below up to the top of the column. The additional cable 4 is connected to the bearing wire 2 by a connection 5.
If the additional cable is a weak current line, an insulating device 6 needs to be arranged between the additional cable 4 and the power transmission iron tower 1, and as shown in fig. 4, an insulating device 6 is also arranged between the additional cable 4 and the force bearing line 2.
If the additional cable is a communication line, an insulating device is not required to be arranged between the additional cable and the power transmission tower, and an insulating device is not required to be arranged between the additional cable and the force bearing line.
The utility model discloses hang the weak electric wire or the communication line of additional cable on the load line, can realize weak electric wire, communication line and high tension transmission line shared channel, avoid opening up new path passageway, effectively improve economic benefits.
Moreover, the weak current line erected on the power transmission line can also have the function of energy consumption equipment on a power transmission line iron tower or the line, the power supply performance is more stable and reliable, and the variety of the energy consumption equipment on the iron tower can be effectively expanded.
