Problems solved by technology

At present, when replacing the utility poles, it is necessary to cut off the power transmission line, which seriously affects the life of users and the production of electricity. When replacing the utility poles, it is necessary to use a crane to pull the utility poles upwards from the transmission lines. In the process of pulling out, the transmission line is scratched due to shaking, causing the transmission line to be worn or even broken, which brings unnecessary workload to the maintenance of the transmission and distribution network and seriously affects the quality of power supply service

Embodiment Construction

[0022] Such as figure 1 As shown, the method of replacing the utility pole with electricity, the specific steps are as follows:

[0023] 1. Deliver the workers wearing insulated protective clothing to the cross arm 2 at the top of the utility pole 1 through the insulated bucket arm truck, and use the insulating masking blanket 4 to insulate and wrap the transmission line 3;

[0024] 2. Untie the transmission line 3 from the cross arm 2 at the top of the utility pole 1, and tie the pull wires on the utility pole 1 under the cross arm 2;

[0025] 3. Send the workers to the ground through the insulated arm truck, and set up the support rod 6 between the transmission line 3 and the ground, so that the transmission line 3 is above the cross arm 2;

[0026] 4. Excavate an inclined pit 5 at the root of the utility pole 1, the inclined pit 5 extends along the direction of the transmission line 3, and the width of the inclined pit 5 is as large as the diameter of the utility pole 1, a...

Abstract

The invention provides a method for replacing a telegraph pole in an electrified state. The method comprises the following specific steps that 1, an insulation shielding blanket is used for wrapping a power transmission line in an insulation mode; 2, the power transmission line is removed from a cross arm at the top end of the telegraph pole; 3, an inclined pit extending in the direction of the power transmission line is dug in the root of the telegraph pole; 4, the telegraph pole is put down along the inclined pit; 5, the telegraph pole is pulled out of the inclined pit, and a new telegraph pole is put into the inclined pit; 6, the new telegraph pole is vertically erected; 7, the inclined pit is backfilled, the ground around the new telegraph pole is tamped, and the power transmission line is fixed to a cross arm of the new telegraph pole; and 9, the insulation shielding blanket is taken down. According to the method, the telegraph pole can be replaced in the electrified state, the living and production electricity utilization requirements of users are met, in the telegraph pole replacing process, the telegraph pole is put down or erected in the extending direction of the power transmission line, the telegraph pole and the power transmission line are not scraped or collided, the power transmission line is prevented from being damaged, unnecessary workloads are reduced, and the power supply service quality is improved.

Description

technical field [0001] The invention relates to a method for replacing a utility pole, in particular to a method for replacing a utility pole with electricity. Background technique [0002] As the name implies, the utility pole is a pole for erecting wires, which is an important part of the power transmission and distribution network. At present, when replacing the utility poles, it is necessary to cut off the power to the transmission line, which seriously affects the life of users and the production of electricity. When replacing the utility poles, it is necessary to use a crane to pull the utility poles upwards from the transmission lines. In the process of pulling out, the transmission line is scratched due to shaking, causing the transmission line to be worn or even broken, which brings unnecessary workload to the maintenance of the transmission and distribution network and seriously affects the quality of power supply service. Contents of the invention [0003] In o...
