Embodiment Construction
[0020] An operation method for replacing overhead wires and ground wires. The operation method in this embodiment includes the following steps:
[0021] Step 1: Put on a plurality of guide rings distributed along the extension direction of the old line on the old line that is overlapped between the two poles and towers to be removed, and the guide ring is overlaid on the old line through sleeves;
[0022] Step 2: Pull the new line to be replaced into each guide ring through the traction rope passing through each guide ring in turn until the length of the new line meets the replacement requirements, and then fix the new line between the two towers;
[0023] Step 3: Remove the old wire to be dismantled from the two-pole tower, and each guide ring is lapped on the fixed new wire, and the old wire is pulled out of each guide ring to complete the overhead replacement of the new and old wire.
[0024] In the above step 1, each guide ring is respectively connected with a guide ring rope, and ...

The invention provides an operation method for replacing overhead wires and ground wires, which includes the following steps: step 1, wearing a plurality of guide rings distributed along the extending direction of the old wires on the old wires overlapping between two towers to be removed, The guide rings are threaded and lapped on the old wires; step 2, the new wires to be replaced are drawn and threaded into each guide rings through the traction ropes passing through each guide ring in turn, until the length of the new wire meets the replacement requirements, and then The new line is fixed between the two towers; step 3, the old line to be removed is removed from the two towers, each guide ring is lapped on the fixed new line, and the old line is pulled out from each guide ring , to complete overhead replacement of old and new lines. During the entire construction process, there is no need to set up a spanning frame. The new line and the old line are respectively supported by the lap of the guide ring. There will be no problem of the new line and the old line falling to the ground. The operation is fast and convenient, and the safety is high.
Description
Technical field [0001] The invention relates to an operation method for replacing overhead wires and ground wires. Background technique [0002] In recent years, with the rapid development of the national economy, the scale and density of power lines have also been increasing. Affected by objective conditions such as roads and railways, some lines need to be replaced with new conductors and ground wires, such as meeting the force of towers. Large cross-section wires under conditions, or replace existing wires with new heat-resistant wires, etc., to increase the current carrying capacity of the line; or replace the ground wire and increase the optical cable ground wire to meet the communication requirements; or in the old wire , When the ground wire is damaged, maintenance and replacement are required. The traditional method of replacing overhead wires and ground wires is to remove the old wires and ground wires first, and then install new wires and ground wires between the corre...
