Description

Method for emergency repair of non-self-supporting pole and stay wire of transmission line and backup protective connector to connect stay wire

technical field

The invention relates to a method for connecting high-voltage electric pole and tower stay wires. the

Background technique

Now we can see guy wire towers everywhere in our life, but the guy wires of the guy wire towers often have broken strands or the UT clips of the bottom handle are lost. The instability of the tower also caused certain difficulties for reconnecting the guy wires. Therefore, when the multiple guy wires of the guy wire tower were broken or the UT clamps were lost, the tower collapsed accident could be caused because the guy wires could not be connected in time. the

According to the invention, the method for using the non-self-supporting pole and tower stay wire of the power transmission line and the backup protection connector to connect the stay wire is realized by using the power transmission line non-self-supporting pole tower stay wire rush repair and the backup protection connector. Connectors include clamps, flexible cables, two-way hooks and ground anchor connectors;

One end of the flexible connecting line is connected to the pull ring of the cable clamp, and the other end of the flexible connecting line is connected to the hook at one end of the two-way hook. The ground anchor connector includes a shackle and a fixing plate. The hook at the other end is connected to the shackle of the ground anchor connector; the fixed plate is connected to the ground anchor;

It is characterized in that the method of using the non-self-supporting pole and tower cable of the transmission line for emergency repair and the backup protection connector to connect the cable

The specific steps are:

Step 1. Use the wire clamp to clamp the stay wire of the pole tower;

Step 2. Connect the pull ring of the cable clamp to one end of the flexible cable;

Step 4. Connect the other end of the soft connecting line to the hook at one end of the two-way hook, and connect the other end of the two-way hook to the shackle of the ground anchor connector;

Step 5. Connect the ground anchor connector to the ground anchor;

Step 6. Adjust the guy wires and flexible connecting wires so that the guy wires are in a tight state, and complete the emergency repair of the non-self-supporting pole tower guy wires of the transmission line and the backup protection connectors to connect the guy wires. the

In the present invention, when the strands of the pull wire are broken or the UT clip is lost, the wire clamp is used to clamp on the intact part of the damaged pull wire, the ground anchor connector is connected to the ground anchor, and the force of the combined pull wire is adjusted through the load-bearing screw. , in a short period of time, the load-bearing function of the damaged cable can be restored in time, avoiding the damage of the cable; the fast connection of the cable is realized, and the accident of the transmission line falling down due to the failure to connect in time and the loss of the load-bearing function is reduced. Even cause power outages to the power grid and society. the
