Description

Bird landing prevention device for transmission towers{APPARATUS FOR PREVENTING BIRDS LANDING FOR POWER LINE TOWER}

The present invention relates to a transmission tower-specific bird landing prevention device developed for the purpose of preventing bird landing of a transmission tower, and detects birds, especially birds of prey (eagles, kites, owls, owls, etc.) that attempt to land or land on the arm of a transmission tower with an ultrasonic sensor. Accordingly, it relates to a bird landing prevention device exclusively for a transmission tower that drives a warning flasher/beep speaker to drive away and prevents flashover failure caused by bird excrement or bird contact.

Currently, about 30 to 40 failures of transmission towers occur annually, and about 50% of them are caused by raptors.

Most of these types of bird breakdown are caused by insulator contamination by raptor's excrement or instantaneous electrical path generation due to excrement, and some direct insulators breakdown due to arcing horn flashover due to landing of raptors.

Therefore, the occurrence of transmission accidents caused by birds of prey causes enormous losses as an accident at one time and causes social problems, so a device for preventing landing of birds of prey is required to prevent this in advance.

For such a device for preventing landing of birds of prey, KEPCO has installed and operated a built-in pylon (windmill type) and suspension type pylon (radiative) bird landing prevention device nationwide since it was developed in 2011 to prevent breakdowns caused by birds.

However, there is a problem in that there is no movement in the case of a windless wind, and in the case of raptors active at night, it is not recognized. In other words, there is a disadvantage in that the function to prevent failures caused by birds of prey during no wind and at night.

In addition, in the case of the windmill type bird landing prevention device, civil complaints are received by the nighttime "beep~~" sound due to the wear of the bearing inside the rotating part, or in the case of the radial bird landing prevention device, the debris caused by the fall of the wire + misdirection. If a person steps on a rice paddy or field without being aware of it, civil complaints arise due to the risk of injury.
