Power transmission line insulation bird damage prevention method

Abstract

The invention relates to a bird damage prevention method, and particularly discloses a power transmission line insulation bird damage prevention method which is suitable for a 35 kV to 220 kV line. The structure main points are as follows: a lead insulation sheath, a metal fitting insulation protection box and an insulation hot melt wrapped belt are arranged; the lead at the cross-arm side of a power transmission line is wrapped by the lead insulation sheath; the metal fitting insulation protection box is adaptive to metal fittings connected with leads in terms of shape, and the metal fittings are wrapped by the metal fitting insulation protection box; and the insulation hot melt wrapped belt is wound on insulator chain grading rings connected with the metal fittings. According to the invention, breakthroughs are made in the adoption of an idea of insulating and isolating bird damage, and various line damage traces of the activities of birds are isolated so that the method is quite practical and also reliable in bird damage prevention effectiveness, the rate of trip-out failures caused by the bird damage can be effectively reduced, and the safe and reliable operation of the power transmission line can be guaranteed, thus excessive activities that interfere with the birds are unnecessary, peaceful co-existence with the birds can be realized, and the ecological environment is protected.

Description

technical field [0001] The invention relates to a method for preventing bird damage, in particular to a method for preventing bird damage by insulating power transmission lines, which is suitable for 35kV--220kV lines. Background technique [0002] Bird damage has always been a very difficult production problem that the power operation department has to face. With the continuous development of human society, the construction of many large-scale facilities, such as high-speed railways, highways, industrial zones, and development zones, has destroyed the natural ecological environment that birds rely on for survival. The number of birds nesting and breeding in dangerous parts of line towers is increasing year by year, which has caused great harm to the safe operation of transmission lines. Statistics in recent years show that the number of line tripping failures caused by bird activities is increasing year by year, and bird damage has become one of the important factors affec...

Problems solved by technology

[0003] Most of the existing technologies solve the problem of bird damage by driving away birds. Devices such as wind-driven bird repellents and ultrasonic bird repellents have been developed. However, wind-driven bird repellents are greatly affected by the environment, and only available It can be effectively applied in windy climates, while ultrasonic bird repellents are extremely expensive, and after a certain period of use, due to the natural adaptability of birds, their effectiveness will be greatly reduced, so they cannot effectively reduce the danger of birds on line towers number of nests

In addition, there is also a method of occupying space to solve the problem of bird damage: fill the favorite nesting position of birds with a device with a certain space, so that birds cannot nest in dangerous parts of towers, as disclosed in patent application 2013100892610 A new type of anti-bird damage placer is provided. Although this type of anti-bird damage device occupies the position where birds are used to nesting, it is impossible to occupy all the positions of the pole tower. Birds can still nest and reproduce in other positions on the cross arm , so the utility is limited, and it is difficult to greatly reduce the trip failure rate of bird damage
