Description

Self-supporting type vertical tower ground wire bird-preventing device in shape like Chinese character 'gan' for power transmission line

Technical Field

The utility model relates to an electric power drives bird equipment technical field, especially relates to a transmission line self-supporting does style of calligraphy and holds vertical tower ground wire anti-bird device.

Background

In recent years, with the improvement of ecological environment and the enhancement of the protection consciousness of people on wild animals, birds move more frequently, and the number of line faults caused by the birds also obviously increases. When birds defecate, nest, fly, peck, etc. on the line, they cause damage to the transmission line equipment or cause tripping, malfunction and stoppage of the line, which is called bird damage. Bird damage generally includes bird's nest, bird's feces, bird's body short circuit and bird pecking. Bird nest type means that when birds nest on the shaft tower, longer bird nest material reduces or short circuit air gap, leads to the circuit trip. Bird droppings form a conductive channel when birds leak droppings near a tower, so that an air gap of the tower is punctured, or the bird droppings are attached to an insulator to cause surface flashover, so that a line is tripped. The bird body short circuit type means that the bird body reduces the air gap distance between line phases (poles) or between the phases (poles) and the ground, so that air breakdown causes line tripping. Bird pecking refers to that birds peck and damage the umbrella skirt or the protective sleeve of the composite insulator, so that the insulator is damaged, and the safe operation of the power transmission line is endangered.

At present, the measures for preventing the bird damage of the line mainly comprise: bird blocking and bird repelling and a combination mode of 'driving, blocking and dredging'. The measures for preventing and controlling the bird nest faults mainly comprise bird prevention boxes, bird prevention baffles and the like; common control measures for bird droppings include: bird spikes, bird baffles, bird droppings prevention insulators, bird shielding cases, bird insulation coatings, bird prevention needle plates and the like; in addition, devices such as a windmill type bird scaring device and an intelligent acousto-optic bird scaring device can be used for scaring birds, or the devices are guided in the mode of an artificial bird nest and a bird perching frame, so that the safe operation of a line is prevented from being damaged by bird activities. At present, birds are prevented from inhabiting a tower by means of bird prevention, the birds begin to inhabit a ground wire damper in recent years, and discharged bird droppings easily cause short circuit jumper wire angle steel end and an electric gap between the damper to cause line tripping because the birds defecate on the ground wire damper.
