Description

Insulation support device between conductors

Technical field:

The utility model relates to the field of electric power transmission, in particular to an insulation device erected on the same pole with double circuits in 10KV rural lines.

Background technique:

At present, the erection methods of 10KV electric power lines in my country are complicated, and the grid structures are diverse. Facing the continuous expansion of urban development, there is a shortage of 10KV distribution network lines. Therefore, it is often necessary to adopt the same pole erection form. However, the actual situation is that the rural grid line erected in the early days has a large distance and a large vertical arc of the conductor. Even if the two lines use JKLY-185 insulated conductors, when the wind force reaches level 4 and above, Phase-to-phase short circuit is very easy to occur, causing the entire line to trip or even fail. And when dealing with line faults, because they are erected on the same pole, if any one of the two lines loses power, the other must also be shut down, which greatly affects the power supply reliability index, loses a lot of power, and causes a waste of resources. The normal life of the people and the economic benefits of power supply enterprises.

Utility model content:

The technical problem to be solved by the utility model is to provide an insulating support device between conductors for the above deficiencies. The 10KV distribution network is safe, stable, and reliable, and has the advantages of small size, low cost, light weight, and easy material selection.

The technical scheme that the utility model adopts is:

An insulating support device between conductors, which is composed of an insulator and equipment clamps connected at both ends of the insulator. The connection between the two ends of the insulator and the equipment clamps is an arc-shaped universal connection, which has solved the gravity effect on the device on the conductors. The equipment clamps There are hoisting holes and screw rods on it.

In order to ensure the arc-shaped universal connection between the two ends of the insulator and the equipment clamp, the hanging openings at the two ends of the insulator have arc-shaped joints, and the connection position of the equipment clamp has a corresponding arc-shaped groove.

In order to ensure the insulation quality, the insulator adopts the applicable composite insulator.

In order to ensure the connection strength, there are connecting screws between the two ends of the insulator and the equipment clamps.

The two ends of the insulator are provided with metal washers, and the metal washers are pierced and connected on the connecting screws.

The total length of this device is 50CM, and after installation, it meets the requirements for distance length and weight between double-circuit wires on the same pole.

The beneficial effect that the utility model can reach is:

1. The utility model has the advantages of ingenious structural design, small size, low cost, light weight, easy material selection, easy installation, convenient carrying and replacement, etc.

2. The utility model adopts ingenious combination of insulators and live equipment clamps, which avoids the waste of power resources, saves unnecessary power loss, and ensures the safe, stable and reliable operation of the 10KV distribution network. In the 10KV distribution network within the scope of the trial, the trial effect of the 100-antenna is remarkable. Since the use of the 11-board 100-new line and the 30-board 100-water line, there has been no interphase short-circuit power failure or failure caused by wire collision. The success rate up to 100%.

3. The overall size and weight of the utility model are satisfied between two 10KV line conductors with a large distance and erected on the same pole, and have a wide range of applications.

The suitable installation position of the device is located in the middle of the vertical arc of a conductor with a relatively large distance or at a certain point above the vertical arc of the two double-circuit lines on the same pole. There are two situations in the field installation of this equipment: 1. Both ends of the line are live and operated at the same time. First of all, two operators are required to be on both sides of the line where the equipment needs to be installed at the same time, and use the elevator to climb to the appropriate position; then use the gram stick to lift the device from the hoisting hole 6 at the same time, and hang the two ends of the device at the same time and respectively. The corresponding positions of the two lines; two operators rotate the screw rod 7 at the same time to fix the wires. 2. Use live-operated insulated arm trucks. After the operator boards the trolley, he can insert the lifting hole 6 with a ring gram rod to fix one end of the equipment to the corresponding position of one of the lines in the object line, and then fix the other end of the equipment at the corresponding position of the other line.
