Embodiment 1

[0031] Such as Figure 1~3 As shown, a UHV transformer noise reduction protection device includes four noise reduction protection units arranged around the UHV transformer 1. The noise reduction protection unit includes a slide rail 2, an electric slider 3, a runner 4 and a sound insulation A piece 5, a plurality of electric sliders 3 are slidably arranged on the slide rail 2, each of the electric sliders 3 is rotatably connected with a runner 4, each of the runners 4 is fixedly arranged A sound insulation sheet 5; both sides of the slide rail 2 are provided with a drive mechanism for driving the plurality of runners 4 to rotate, and a telescopic mechanism for controlling the drive mechanism to move away from or approach the runner 4 .

[0032] Described runner 4 comprises rotating shaft 41 and wheel body 42, and described wheel body 42 is fixed on the middle part of described rotating shaft 41, and the lower part of described rotating shaft 41 is arranged on the described el...

Embodiment 2

[0037] Such as Figure 4~5 As shown, the UHV transformer noise reduction protection device of the embodiment of the present invention differs from the first embodiment in that:

[0038] The telescoping mechanism includes a screw rod 14 and a motor. The left and right parts of the screw rod 14 have opposite threads. Screw holes are arranged at both ends of the bottom frame 6, and the two bottom frames 6 are connected by two screw rods 14. The screw rods 14 are all driven by the motor; two pulleys are arranged under the bottom frame 6, and two slide grooves are arranged on the outside of the slide rail, and the pulleys are located in the slide grooves.

[0039] One end of two described screw rods 14 is all provided with second bearing 17, and end portion is all provided with first belt pulley 15, and two described second bearings 17 bottoms are provided with support fixed bar 16, and the output shaft of described motor is provided with second The pulley, the second pulley is co...

Embodiment 3

[0043] Such as Figure 6 As shown, the UHV transformer noise reduction protection device of the embodiment of the present invention differs from the first embodiment in that:

[0044] The telescopic rod is an electric telescopic rod. It also includes a noise sensor, a control system and an intelligent terminal. The noise sensor, the electric slider, the drive motor and the telescopic rod are all connected to the control system through signal lines, and the control system is connected to the intelligent terminal.

Abstract

The invention discloses an extra-high voltage transformer noise reduction protection device and method, and belongs to the technical field of electric power operation and maintaining. The extra-high voltage transformer noise reduction protection device comprises four noise reduction protection units arranged on the periphery of an extra-high voltage transformer, each noise reduction protection unit comprises a sliding rail, electric sliding blocks, a rotating wheel and a sound insulation piece, and the multiple electric sliding blocks are arranged on the sliding rail in a sliding mode; and each electric sliding block is rotationally connected with one rotating wheel, and each rotating wheel is fixedly provided with one sound insulation piece. Driving mechanisms used for driving the rotating wheels to rotate and telescopic mechanisms used for controlling the driving mechanisms to be away from or close to the rotating wheels are arranged on the two sides of the sliding rail. The extra-high voltage transformer can be subjected to noise reduction and protection, and has the advantages of being good in heat dissipation performance and convenient to overhaul.

Description

technical field [0001] The invention relates to the technical field of electric power operation and maintenance, in particular to an ultra-high voltage transformer noise reduction protection device and a method thereof. Background technique [0002] In recent years, due to the advantages of UHV AC and DC power grids in long-distance power transmission, cross-regional networking and flexible dispatching, they have developed rapidly. With the development of power grid construction, UHV AC and DC projects will have higher and higher requirements for environmental protection. ; UHV AC / DC projects must ensure the environment, but in the new problems that have appeared in the running DC transmission projects, the noise sources of UHV converter stations include converter transformers, smoothing reactors, AC filter banks and valve cooling equipment, etc. , where the converter transformer is the most important noise source, the main body noise of the transformer comes from the iron c...
