Description

Method for replacing telegraph pole in electrified manner

Technical Field

The invention relates to a method for replacing a telegraph pole, in particular to a method for replacing the telegraph pole with electricity.

Background

Telegraph poles, as their name implies, are poles of electric power lines, which are important components of transmission and distribution networks. At present, when a telegraph pole is replaced, power needs to be cut off for a power transmission line, life and production power consumption of a user are seriously affected, and when the telegraph pole is replaced, the telegraph pole needs to be pulled out upwards from between the power transmission line by a crane, the telegraph pole is scraped and touched the power transmission line due to shaking in the upwards pulling-out process, so that the power transmission line is abraded or even fractured, unnecessary workload is brought to maintenance of a power transmission and distribution network, and power supply service quality is seriously affected.

Disclosure of Invention

The invention aims to solve the technical problems and provides a method for replacing a telegraph pole in a live state, which can replace the telegraph pole in the live state, ensure the living and production electricity consumption requirements of users, and can lay down or erect the telegraph pole along the extension direction of the transmission line in the process of replacing the telegraph pole, so that the telegraph pole is not scratched to the transmission line, the transmission line is prevented from being damaged, unnecessary workload is reduced, and the quality of power supply service is improved.

The technical solution of the invention is as follows:

the method for replacing the telegraph pole in an electrified way is characterized by comprising the following specific steps:

1. conveying the operating personnel wearing the insulating protective clothing to a cross arm at the top end of a telegraph pole through an insulating bucket arm vehicle, and insulating and wrapping the power transmission line by using an insulating shielding blanket;

2. the power transmission line is disassembled from the cross arm at the top end of the telegraph pole, and a stay wire is tied on the telegraph pole below the cross arm;

3. the method comprises the following steps that an operator is delivered to the ground through an insulating bucket arm vehicle, an inclined pit is excavated at the root of a telegraph pole, the inclined pit extends along the direction of a power transmission line, and the width of the inclined pit is as large as the diameter of the telegraph pole;

4. slowly releasing the pull wire to lay down the telegraph pole along the inclined pit;

5. pulling the telegraph pole out of the inclined pit and placing the telegraph pole into a new telegraph pole;

6. tying the pull wire at the position of the new telegraph pole below the cross arm, and pulling the pull wire to vertically erect the new telegraph pole;

7. backfilling the inclined pits, and tamping the ground around the new telegraph pole;

8. conveying the operating personnel wearing the insulating protective clothing to the cross arm at the top end of the new telegraph pole through an insulating bucket arm vehicle, and fixing the power transmission line on the cross arm of the new telegraph pole;

9. the operator takes the insulating shielding blanket down and sends the blanket to the ground through the insulating bucket arm vehicle.

Further preferably, the inclination of the inclined pit is 20-30 degrees.

Preferably, after the power transmission line is disassembled from the cross arm, the support rod is erected between the power transmission line and the ground, so that the power transmission line is positioned above the cross arm, and the power transmission line is prevented from being scratched by the cross arm in the laying process.

The invention has the beneficial effects that:

1. through wearing insulating protective clothing operation and shielding the blanket parcel transmission line through insulating, realize that the operation personnel dismouting transmission line under the electrified state, guarantee user's life, production power consumption demand.

2. Because the root of the telegraph pole is excavated into the inclined pit which extends along the direction of the power transmission line and has the width equal to the diameter of the telegraph pole, the telegraph pole does not scrape and collide with the power transmission line when the telegraph pole is laid down or erected along the inclined pit, the power transmission line is prevented from being damaged, unnecessary workload is reduced, and power supply service quality is improved.
