Description

Technical Field

[0001] The present invention relates to a multi-dimensional semi-active hard jumper anti-wind deviation device, belonging to the technical field of transmission tower lines. Background Art

[0002] Wind deviation of transmission lines refers to that under the action of strong winds, conductors or jumpers are affected by lateral winds and deviate from their vertical positions. When the electrical clearance between the wind-deviated conductor and the transmission tower or other conductors is shortened, flashover discharge accidents are likely to occur, resulting in the outage of the transmission line and seriously affecting the safe and stable operation of the power system. Especially in ultra-high voltage lines, wind deviation accidents will seriously affect power supply reliability and cause huge economic losses. For strong wind areas of transmission lines, the commonly used anti-wind deviation measures mainly include four types: installing anti-wind guy wires, installing weights, installing support insulators, and using anti-wind deviation insulators. However, there is currently no mature and effective anti-wind deviation scheme for the jumpers connected to the I-string of tension towers. Therefore, it is necessary to carry out relevant research on the anti-wind deviation of hard jumpers connected to the I-string.

[0003] Therefore, the present invention proposes a multi-dimensional semi-active hard jumper anti-wind deviation device, which is installed outside the hard jumper cage. Based on the wind deviation induction and wind direction induction devices, the hydraulic components are controlled to realize air compression by solar energy and piezoelectric materials. After the compressed air is released, thrust is generated to achieve the effect of preventing the jumper from deviating due to wind. Summary of the Invention

[0004] The purpose of the present invention is to provide a multi-dimensional semi-active hard jumper anti-wind deviation device.

[0005] In order to achieve the above purpose, the technical solution adopted by the present invention is:

[0006] A multi-dimensional semi-active hard jumper anti-wind deviation device includes a first group of components, a second group of components, and a third group of components;

[0007] The first group of components includes an outer box and a hoop connected to the outer box. The side of the outer box opposite to the hoop is a curved surface.

Inside the wind deviation induction device, there is a box body containing small balls with odd masses. In the middle of the bottom of the box body, there is a groove, which is matched with a rolling device inside the wind deviation induction device. The box body can move diagonally up and down or diagonally down and up with the rolling device as the fulcrum under the action of the mass balls. The lower right corner of the box body is set as a curved surface. When a certain wind deviation occurs, the box body moves to make the curved surface close to and contact the piezoelectric material on the lower right side inside the wind deviation induction device. The piezoelectric material is connected to a solar energy supply device and a power hydraulic rod through a circuit. When the curved surface contacts the piezoelectric material, the power hydraulic rod is powered on and started. On one side of the wind deviation induction device, there is a hydraulic rod electric return device, which is connected to the piezoelectric ceramic and the hydraulic rod respectively through a circuit. On the non-curved surface side of the wind deviation induction device and the hydraulic rod electric return device, there is a series-connected automatic hydraulic system.

[0010] A further improvement of the technical solution of the present invention is that: the hoop is connected to the outer box through bolts.

[0011] A further improvement of the technical solution of the present invention is that: the solar energy supply device is arranged in a uniformly segmented manner.

[0012] A further improvement of the technical solution of the present invention is that: the automatic hydraulic system includes a series-connected power hydraulic rod side subsystem and a hydraulic rod side subsystem. The power hydraulic rod can squeeze the filling liquid towards the hydraulic rod direction. On the curved surface side of the hydraulic rod, there is a hydraulic rod member baffle. On the outer wall of the hydraulic rod member baffle, a piston oil seal, an anti-pollution oil seal and a wear-resistant ring are sequentially arranged. The wear-resistant ring is connected to a hydraulic rod contact head. On the inner wall surface of the outer box, there is a piezoelectric ceramic matched with the hydraulic rod contact head. The hydraulic rod contact head contacts the piezoelectric ceramic under the action of the hydraulic rod, and the circuit is powered on. Driven by a baffle switch, an opening baffle is opened to release compressed gas to generate a thrust force opposite to the wind deviation direction. At the same time, the hydraulic rod electric return device is started, and the hydraulic rod returns to its original position.

[0013] Due to the adoption of the above technical solution, the technical effects obtained by the present invention are:

[0014] The present invention proposes a wind deviation prevention device for a hard jumper connected in an I-shaped string, which realizes the wind deviation prevention effect of the overall hard jumper structure by generating a thrust force with compressed air.

[0015] The present invention realizes the power supply of the overall wind deviation prevention device based on solar energy, avoiding the influence of power supply methods such as magnetoelectric generation in high-voltage transmission lines.
