Product Remarks: Recommended new product-Ultrasonic Bird Repeller Product Category: Bird Repeller Series

I. Overview

    Birds like to build nests on iron towers during the breeding season. The nesting materials include branches, dead vines, waste cotton thread, and even iron wire. The falling of these materials may short-circuit several porcelain bottles, causing the circuit to trip. Various big birds like to fall on the cross arm of the iron tower after foraging. A large amount of feces are discharged during rest, which will pollute the porcelain bottle, reduce the insulation strength of the porcelain bottle string, and cause the circuit to trip. The bird damage fault points on the line are all on the cable or steel tower, and most of them are on the central line porcelain string of the straight line tower and the tensile central line jumper suspension insulator string. Cement poles generally have no bird damage. In substations, birds often get into the gaps of transformers or AC filters to cause transient faults.

    Ultrasonic bird repellent is a bird repellent product specially designed for the power sector. It is powered by solar panels and batteries. It is especially suitable for outdoor pole towers and substations that are inconvenient to provide power. As long as one high-voltage iron tower is installed, it can ensure that it will not be disturbed by birds.

Second, the principle of ultrasonic bird repellent

    The ultrasonic bird repeller is an ultra-low power ultrasonic generation system designed and manufactured by imported single-chip microcomputer. The ultrasound emitted by it stimulates the nervous system of birds, destroys the living environment of birds, and stays away from the area covered by ultrasound. Because the system uses constantly changing ultrasonic frequencies and different working mechanisms, birds cannot adapt to it, ensuring the durability of the bird repellent effect. Its characteristics are: low voltage, ultra-low power consumption, reliable performance, long service life, and small maintenance.

3. Main features of ultrasonic bird repeller

1. After installation, turn on the power switch. At this time, the indicator light is on and 6KHz low-frequency ultrasound is emitted for about 10 seconds. At the same time, the working indicator light flashes at a rate of 1 second. Enter the working state after 1 minute.

2. During normal work, the bird repellent works at the speed of "work: stop=2:15" during the day, that is, it works for 2 minutes and stops for 15 minutes; the evening is the time when birds are concentrated, and the bird repellent increases the work ratio according to " Work: stop=2:10" speed work, that is, work for 2 minutes and stop for 10 minutes. In order to save energy and extend the service life of the bird repellent in the middle of the night. It automatically changes to the “2:15” ratio during the day. When the bird repeller emits ultrasonic waves, the indicator status circulates at the speed of "on 1 second→off 1 second→on 1 second→off 9 seconds".

3. The frequency of the ultrasonic bird repellent is 12 KHz～25 KHz. For 2 minutes of work, one minute is sweep frequency, and one minute is fixed frequency. Sweep frequency is to continuously change frequency points and cyclically work in the frequency band of 12KHz～25KHz. The cycle speed is 3.8 seconds, and the fixed frequency is to randomly select a frequency point to work for 1 minute.

4. The recess under the bird repeller is equipped with a rocker switch and a high-brightness light-emitting diode. There will be no misoperation during transportation and installation; the luminous tube is convenient for inspectors to observe the working status of the bird repellent.
