Research On Anti Bird Device Of Transmission Line Based On Active Detection Technology

In recent years,the bird tripping fault for Hebei Hengshui power grid fault tripping in increasingly high proportion,has become one of the main failure fault of power system safe and stable operation.Although the anti bird has taken a number of measures,but either the bird is not in place,anti bird device and part bird region selection caused by improper anti bird effect or anti bird when,cause a lot of unnecessary economic losses.Therefore,it is necessary to analyze the actual situation of transmission line for different categories of bird,bird and tower level difference bird control,anti bird device developed properly,enhance the effect of driving birds.In the analysis of bird types in Hengshui area and distribution on the basis of the use of reflective infrared sensors and ultrasonic generator,designed a kind of infrared induction bird driving device.The sensing principle of infrared sensor is analyzed,and the influence of the distance,the number,the size of the bird and the flight speed of the infrared sensor are discussed.The ultrasonic wave driving system is introduced,and the ultrasonic transmission distance and sound intensity attenuation are analyzed.The experimental results show that the hardware circuit is simple,the system has strong anti light interference,the ultrasonic distance is far away,the environmental protection is strong,and can achieve the effective flooding effect.
