Description

A 10KV line anti-bird damage cross arm

technical field

The utility model relates to the technical field of power transmission line equipment, in particular to a 10KV line anti-bird damage cross arm.

Background technique

With the strengthening of human awareness of the protection of the natural ecological environment and the implementation of the policy of banning hunting and returning farmland to forests, human beings have created a better environment for the survival of birds. The types and numbers of birds have gradually increased, and the scope of activities has gradually expanded. With the development of the power grid, if the transmission lines do not take targeted anti-bird measures, the degree of harm will also increase. When birds build nests on power transmission lines, they fly with objects such as branches, iron wires, firewood, etc. in the air above the line or between the wires. After the bird's nest is blown away by the wind, the nesting object falling on the live wire or insulator can also cause a short circuit in the line. Bird droppings will adhere to the insulating surface of the transmission line. Under humid conditions, its soluble substances gradually dissolve in water, forming a conductive film on the insulating surface, which reduces the insulation level of the insulator. The flashover will affect the safe operation of the transmission line. Bird damage accidents will cause large-scale power outages, directly affecting the safety, stability and reliable power supply of the power grid.

Preventing birds from building nests on the crossarm of 10kV power lines has become a major problem. The electric power department spent a lot of manpower and material resources to patrol the line and remove the bird's nest, and some of them needed power outages to clean up, which seriously affected the reliability of power supply. Bird damage is one of the main faults that endanger the safe operation of transmission lines. Therefore, how to effectively prevent it is of great significance to ensure the safe operation of transmission lines. At present, the existing anti-bird measures include hanging red flags on the top of towers, installing wind chimes, reflective windmills, plastic windmills, etc. This method is simple and easy to implement, but the long-term anti-bird measures are poor. The effect of installing anti-bird thorns and controlling the bird's perching position is obvious, but it is difficult to operate and maintain the equipment. Install the anti-bird cover, easy to fall off.

Cross arms of various shapes often used in power lines are usually formed by combining two corner arms with nails and shims. Because the structural structure of this type of cross-arm is easy for birds to build nests thereon, and the building of these bird's nests often causes grounding or tripping accidents. It has always been a difficult problem for the power sector that birds build nests on the cross arms of poles and towers, especially now that we are all advocating ecological balance to protect birds, and this phenomenon is increasing. It often causes line tripping and seriously affects the operation safety of power lines. On the crossarm of 10KV power lines, we often see bird nests. These nests are generally magpie nests. Magpies are birds with strong adaptability, and they like to build their nests on tall trees or on the crossarm of 10KV power lines.

The patent application No. 200320107233.9 discloses a bird-proof power transmission line cross arm, which is to solve the technical problem in the prior art that birds are easy to nest on the cross arm and cause short circuit of the wire. The utility model is realized through the following technical scheme: the top surface of the cross-arm of the power transmission line for preventing bird damage is a downwardly inclined slope. Because the utility model adopts the above-mentioned structure, birds cannot build nests on the cross-arm, thereby effectively avoiding the occurrence of short-circuit accidents caused by bird nests; Stay on the cross arm; in addition, a fixed block is provided at the fixed end of the cross arm, and a screw hole for fixing is provided on the fixed block. The hole can be fixed, the structure is simple, and the assembly and disassembly are convenient, but the effect of preventing bird damage of the utility model is not very obvious.
