specific Embodiment 1

[0018] The structure schematic diagram of the power tower bird repelling device of this embodiment is as follows figure 1 as shown, figure 1 The dotted line part in represents the foam glue connecting the high-voltage transmission line and the plastic box 1. The power tower bird repelling device is sequentially provided with a circular plastic box 1 and an elliptical shell 2 from the inside to the outside;

[0019] The plastic box 1 is made of insulating material, and the inner ring surface is symmetrically provided with a door, and the inside of the plastic box 1 is filled with foam glue; the high-voltage transmission line passes through the inside of the plastic box 1, and the plastic box 1 is connected to the high-voltage power transmission by the foam glue. The thread is tightly bonded;

[0020] The shell 2 is made of insulating plastic, the plastic box 1 and the shell 2 are connected by a metal hollow tube 3, and the metal hollow tube 3 is located in a plane perpendicul...

specific Embodiment 2

[0025] The bird repelling device for power poles and towers of this embodiment, on the basis of the specific embodiment 1, further defines that the outer surface of the metal hollow tube 3 is connected with a plurality of metal rings through threads, and the metal rings can move along the direction of the metal hollow tube 3 .

[0026] Since the high-voltage transmission line transmits 50Hz alternating current, such a high frequency will cause the magnetic rod 5 to hit the metal hollow tube 3 frequently, which will easily cause rapid fatigue failure of the metal hollow tube 3, reduce the bird repelling effect, and even completely lose it in severe cases. Bird repellent effect. In view of this problem, the scheme of the second embodiment is designed, by adjusting the position of the metal ring on the metal hollow tube 3, the magnetic rod 5 is hit on the metal ring, avoiding the direct collision between the magnetic rod 5 and the metal hollow tube 3, if the metal Ring fatigue fa...

specific Embodiment 3

[0028] The power pole tower bird repelling device of the present embodiment, on the basis of the specific embodiment one, further defines the voltage U of the high-voltage transmission line, the length L of the magnetic rod 5, and the duty ratio k of the metal hollow tube 3, and satisfies the following conditions:

[0029] L = 2.4 U e k

[0030] Wherein, e is a natural constant, the cross section of the metal hollow tube 3 is annular, and the duty ratio k is the ratio of the inner diameter of the annular to the outer diameter of the annular.

Abstract

The invention provides an electric tower anti-bird device, and belongs to the technical field electrical equipment. The electric tower anti-bird device is provided with a circular ring-shaped plastic box and an oval ring-shaped shell from inside to outside in sequence; the plastic box is made of insulating materials, bin gates are symmetrically arranged on the surface of the inner ring, and the plastic box is filled with foam glue; a high voltage transmission line penetrates through the plastic box, and the plastic box and the high voltage transmission line are tightly bonded with the foam glue; the shell is made of insulating plastics, the plastic box is connected with the shell through metal hollow pipes, the included angles between every two adjacent metal hollow pipes have a parameter alpha and a parameter beta, beta is larger than alpha, the metal hollow pipes are arranged in the mode that the included angles alpha and the included angles beta are arranged by turns in sequence, a rotating shaft is arranged between every two metal hollow pipes with the included angle beta, and each rotating shaft is provided with a magnetic rod taking the direction where the rotating shaft is located as the turning axle. According to the electric tower anti-bird device, noise which annoys birds can be sent out, an electric tower can be driven to produce slight vibration, and the effect on driving the birds is achieved.

Description

technical field [0001] The invention relates to a bird repelling device for electric poles and towers, which belongs to the technical field of electric equipment. Background technique [0002] Bird activities will seriously affect the safe operation of the power grid. For example, bird droppings on the insulators of the supporting lines will reduce the flashover voltage of the insulators and increase the probability of tripping the power grid; and birds flying over the power lines in groups may also cause a short circuit in the power grid and cause power accidents. The current statistical results show that the line faults caused by bird activities are second only to lightning damage and external force damage, occupying the third place in the total line faults. It can be seen that if driving birds is an important problem to be solved urgently in the power system at the present stage. Contents of the invention [0003] In order to realize bird repelling, the present invent...
