Abstract
The utility model provides a dismantled and assembled active noise reduction mechanism of transformer substation, including the perpendicular roof beam of two parallels, characterized by: be provided with the crossbeam of two parallels on the perpendicular roof beam, the middle part of crossbeam is provided with the backup pad, the middle part of backup pad is provided with the power, the power -on is crossed control scheme and is connected a set of electron silencer, the both ends of erecting the roof beam all are provided with bends, it inhales the seat all to be provided with magnetic force on bending. The utility model discloses a knob and screw rod screw -thread fit, permanent magnet and screw rod screw -thread fit, magnetic force inhale the seat on an in -process that uses only need lean on the casing at transformer case with equipment, and the wrench movement knob drives the screw rod and rotates, and the permanent magnet just moves down along the screw rod under the effect of screw thread, can with the firm absorption of equipment on substation equipment's casing, the electron silencer can carry out noise elimination work at this moment.
Description
Technical field
The utility model relates to power transformation O&M field, active noise reduction mechanism of especially a kind of removable transformer station.
Background technology
Always the electromagnetic noise that transformer station produces in the process run perplexs a utilization difficult problem in the industry.In transformer station, the electromagnetic noise of excess causes damage can to the hearing of staff, and the electromagnetic noise that the transformer station being arranged on residential block produces also can bring threat to the health of resident.And at present, utilize electronic circuit and sound amplifier to produce sound--the anti-sound contrary with the phase place of noise, offset original noise and reach the technology of noise reduction object, being widely used in electromagnetism noise reduction also referred to as anti-audio technology.
Summary of the invention:
The technical problems to be solved in the utility model is to provide active noise reduction mechanism of a kind of removable transformer station, prevents electromagnetic noise from impacting to the health of staff and neighbouring resident.
The utility model adopts following technical scheme to realize goal of the invention:
Active noise reduction mechanism of a kind of removable transformer station, comprise two parallel vertical beams, it is characterized in that: described vertical beam is provided with two parallel crossbeams, the middle part of described crossbeam is provided with supporting bracket, the middle part of described supporting bracket is provided with power supply, described power supply connects one group of electronics muffler by control circuit, and the two ends of described vertical beam are provided with bending, and described bending is all provided with magnetic force suction base.
As the further restriction to the technical program, described magnetic force suction base comprises suction base, is provided with directed cavity in described suction base, permanent magnet is provided with in described directed cavity, described permanent magnet is through screw rod, and described screw rod is arranged on described suction base by deep groove ball bearing, and described screw rod is provided with knob.
The outside ring set of described control circuit has Universal pipe.
Compared with prior art, advantage of the present utility model and good effect are: knob of the present utility model coordinates with screw flight, permanent magnet coordinates with screw flight, magnetic force suction base only needs equipment to lean against on the housing of power transformation box in the process used, twisting knob drives bolt rotary, permanent magnet just moves down along screw rod under the effect of screw thread, equipment firmly can be adsorbed on the housing of converting equipment, and now electronics muffler can carry out noise elimination work.Whole disassembly process simple and fast, one man operation can complete.EM equipment moduleization designs, can be random be arranged on any converting equipment or be arranged on the position that large-scale converting equipment produces electromagnetic noise, practical.
