Abstract

The invention discloses a noise reduction protection device for an ultra-high voltage transformer and a method thereof, belonging to the technical field of power operation and maintenance. The invention comprises four noise reduction protection units arranged around the ultra-high voltage transformer. An electric slider, a runner and a sound-insulating sheet, a plurality of the electric sliders are slidably arranged on the sliding rail, each of the electric sliders is rotatably connected with a said runner, and each of the runners is A sound insulation sheet is fixedly arranged; both sides of the slide rail are provided with a driving mechanism for driving the plurality of runners to rotate, and a telescopic mechanism for controlling the driving mechanism to be away from or close to the runner. The invention can reduce noise and protect the ultra-high voltage transformer, and has the characteristics of good heat dissipation and easy maintenance.

Description

technical field [0001] The invention relates to the technical field of power operation and maintenance, in particular to a noise reduction protection device for an ultra-high voltage transformer 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 scheduling, 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 and DC projects must ensure the environment, but among the new problems in the existing DC transmission projects, the noise sources of UHV converter stations include converter transformers, smoothing reactors, AC filter banks and valve cooling equipment, etc. , Among them, the converter transformer is the main noise source. The noise of the transformer itself mainly comes from the vibration of the iron...
