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...
