Description

Replacing tension-resistant electric poles without falling off the line

technical field

The invention relates to a method for replacing a tension-resistant electric pole without dropping the line.

Background technique

In the maintenance of rural power grid lines, many 10kv or 400v lines are erected along the roadside. It is often encountered that the pole tower is damaged by vehicles or cracks or even breaks due to aging, especially when two lines in different directions cross on the same pole. Once this kind of pole needs to be replaced, according to the general experience, the wires need to be untied in the tension section where the pole is located, the hardware on the pole is removed, the wires on both sides fall to the ground, the wires and lines on both sides are fastened, and the damaged wires are pulled out Electric poles, new poles were planted, metal wires were restored, and power transmission was resumed. This working method of changing poles not only causes the user to have a power outage for too long, but also has a large workload and many people.

Contents of the invention

The purpose of the present invention is to provide a method for replacing tension-resistant electric poles without falling off the line, which reduces the workload, reduces the number of workers, and shortens the replacement time.

In order to achieve the above object, the present invention adopts the following technical scheme: the method of replacing the tension-resistant electric pole without dropping the line, including the following steps: (1) the line is powered off, and the double-hook tensioner is used to connect the same-phase conductors on both sides of the tension pole. The angle iron connecting plate is connected together, and the angle iron connecting plate is a connecting piece connected between the cross arm on the tension bar and the wire. (2) Remove the cross arm on the tension bar, so that the double hook tensioner and its connected The wires on both sides are in a suspended state. (3) Use a crane to lift out the tension rod, and then plant a new tension rod. (4) Restore the connection of the wires on both sides to the new tension rod, and release the double-hook tensioner. the

The method of replacing the tension-resistant electric pole without falling off the line of the present invention has the beneficial effects of reducing the workload, reducing the staff and shortening the replacement time.

Detailed ways

The method of replacing the tension-resistant electric pole without dropping the line, the tension-resistant pole 6 is a tension-resistant electric pole, before the tension-resistant pole 6 is replaced, as shown in Figure 1, the wire 1 on the side of the tension-resistant pole 6 is connected to the insulator 2, The insulator 2 is connected to the angle iron connecting plate 3, and the angle iron connecting plate 3 is connected to the cross arm 4 of the tension bar 6, that is, the wire 1 on the side of the tension bar 6 is connected to the insulator 2, the angle iron connecting plate 3 and the The cross arm 4 is connected on the tension bar 6, and the angle iron connecting plate 3 is a connecting piece connected between the cross arm 4 and the wire 1 on the tension bar 6, and the cross arm 4 is a tension member fastened on the tension bar 6. Firmware, the wires 1 in the same phase on both sides of the tension rod 6 pass through the middle wire 5 to form a passage, the connection method between the tension rod 6 and the side wires 1, and the connection relationship between the wires 1 on both sides of the tension rod 6, and the horizontal Bearing 4, angle iron connecting plate 3, and insulator 2 are all prior art, so do not describe in detail, when tension rod 6 is replaced, include the following steps: (1) As shown in Figure 2, the power failure of the line, use the double hook tensioner 8 Connect the angle iron connecting plates 3 connected to the same phase conductors 1 on both sides of the tension rod 6 together. The double-hook tensioner 8 is a tool with hooks at both ends and adjustable length for tension adjustment. The double-hook tensioner 8 is the prior art, so it will not be described in detail. The hooks at the two ends of the double-hook tensioner 8 are respectively hooked on the two angle iron connecting plates 3. Of course, the hooks corresponding to the double-hook tensioning device 8 on the angle iron connecting plate 3 are provided with hook holes , (2) As shown in Figure 3, remove the cross arm 4 on the tension bar 6. At this time, the double-hook tensioner 8 connects the wires 1 on both sides through the two-angle iron connecting plate 3, so that the double-hook tensioner 8 and its The wires 1 on both sides of the connection are in a suspended state, and the separation of the wire 1 and the tension rod 6 is completed without affecting the safety of the line. (3) Loosen the soil where the tension rod 6 is buried, and lift the tension rod 6 out with a crane. Plant the new tension bar 6A again, now as shown in Figure 4, (four) as shown in Figure 5, restore the connection of both sides of the wire 1 on the new tension bar 6A, and reinstall the metal tools such as the cross arm 4 on the new On the tension bar 6A, connect the two angle iron connecting plates 3 of the conductors 1 on both sides with the cross arm 4 respectively, and then release the double hook tensioner 8 . At this time, it should be noted that the burial depth and process of the new tension rod 6A meet the standards. Then adjust the sag of wire 1 and resume the power transmission operation. The accompanying drawings of this embodiment only take the wires on both sides of one phase as an example, and the principles of other wires are the same, so they are not shown in the figure.

The method of replacing the tension pole without falling off the line in the present invention is a construction method that is convenient for replacing the original damaged tension pole 6 with a new tension pole 6A, which can reduce the workload, reduce the staff and shorten the replacement time .
