10kV pole type transformer sound arrester of the present invention is to be made up of bracing frame, sound panel, potential device, fixed leg etc., and it is that potential device is installed on fixed leg, is covered with sound panel in the potential device outside, and this sound panel is installed on the fixed leg by fixed mount.Wherein, sound panel is to adopt macromolecular material or composite fibre materials to process, and preferably selects the disposable machine-shaping of polycarbonate material for use.PC (Merlon) is a kind of novel high strength, heat insulation, printing opacity; Light construction material is widely used in lamp box making, hood daylighting, highway barrier, explosion-proof shield, the daylighting canopy of the heavens, industrial premises, warmhouse booth, observation window, sound barrier, exhibition daylighting etc.PC septum pellucidum soundboard is to be specifically designed to the sheet material that road, overhead, highway, track traffic, railway, residential quarters etc. need sound insulation, than common plate better soundproof effect is arranged, ageing-resistant and impact resistance.But utilize the characteristic of natural torsion under the normal temperature, design more perfectly sound barrier.The shape and size of sound panel can produce size and the scope of dry sound and selected arbitrarily according to allocation transformer equipment; Described bracing frame is to be made up of entablature, middle cross beam and trapezoid seat etc.; It is on fixed leg, to connect entablature; Entablature is fastened on sound panel top; Middle cross beam encloses mutually with trapezoid seat and is trapezium structure, is connected on the fixed leg by trapezoid seat upper top, lower bottom part, and middle cross beam is fixedly connected with the sound panel middle part.Sound panel integral body is bracing frame with frame, frame, and contact portion is used rubber blanket, reduces noise, fixes with screw.
The present invention can effectively reduce more than the noise 20dB, and the pole type transformer noise level behind the installation sound panel can effectively be reduced to the national regulation level, and its main performance index is following:
Shock resistance: the shock-resistant energy of PC sound panel is 200 times of same thickness simple glass, is 30 times of polymethyl methacrylate.
Weather resistance: the PC sound panel can keep the stability of each item physical index-40 ℃ to 120 ℃ scopes.
The anti-condensation performance: outdoor temperature is 0 ℃, and indoor temperature is 23 ℃, and indoor relative humidity is lower than at 80% o'clock, and the inner surface of material is dewfall not.
Fire resistance: standard GB 50222-95 is confirmed, the awkward combustion of PC sound panel one-level, i.e. B1 level.
Sound insulation property: can effectively reduce noise 20dB through the thick PC sound panel of test 6mm.
Processing characteristics: the individual layer PC plate vacuum available method of forming and compression moulding method are processed the product of multiple moulding, and double-deck PC plate also can carry out cold roll forming at normal temperatures.
In light weight: the weight of individual layer PC sound panel is 1/2 of same thickness glass; The weight of double-deck PC sound panel is 1/5 of same thickness glass.
Insulating properties: the PC sound panel is all insulation material.
The present invention mainly is: utilize special material and structure to process the transformer sound panel; It is blank to have filled up the field; Can effectively reduce more than the noise 20dB; Pole type transformer noise level behind the installation sound panel can effectively be reduced to the national regulation level, has avoided migration, has transformed the great expense that transformer produces.
