Description

Wedge shunt line ground potential live installation combination tool

technical field

The utility model relates to the technical field of electric power maintenance operations, in particular to a wedge-shaped shunt line ground potential live installation combination tool, in particular a combination tool for installing wedge-shaped shunt lines, which is suitable for ground potential live installation node shunt lines, It can improve the conduction capacity of the conductor and the reliability of power transmission, reduce the temperature of the node caused by the load, and avoid the occurrence of accidents.

Background technique

Due to the influence of factors such as product quality, construction quality, operation and maintenance quality, and harsh weather, power line nodes sometimes experience node overheating. If the overheating of nodes cannot be eliminated in time, it may cause node fusing and disconnection accidents.

In order to avoid such accidents, up to now, power line inspection units mainly need to carry out the following work. The first is to carry out temperature measurement of conductor nodes in a timely manner according to equipment status evaluation and line load conditions. The second is to carry out power-off maintenance or live maintenance for overheated nodes.

The most commonly used maintenance method is power outage maintenance. The maintenance personnel can directly contact the wires for operation, and the operation method is relatively simple. However, a power outage will affect the reliability of power supply, and even affect the power supply load, reducing the power supply. Therefore, live work is often used to install node shunt lines. Since the operation is already in a dangerous state when the node is overheated, in order to reduce the operation risk, the ground potential operation method is usually used to install the bolt type shunt line. The installation method of this bolt-type shunt line is to place the clamp on the wire with a special insulating operating rod, and tighten the clamp bolt with the operating hook to make the clamp fully contact with the wire and play a shunting role. The disadvantage is that the contact area is not enough, the shunting effect is limited, and it cannot be operated for a long time.

The contact area between the wedge-shaped shunt line and the conductor is sufficient, the wedge tight effect is good, and it can run for a long time. If the ground potential installation can be carried out, the shunting effect of the shunt line will be greatly improved, and the deficiency of the existing bolt type shunt line will be made up for.
