The Japanese patent application No.2012-230501 of the application based on submitting on October 18th, 2012 and the priority that requires this application; The overall content of this application is also incorporated herein by reference.
Technical field
The embodiments described herein relates generally to Static Electro induction device.
Background technology
In recent years, the angle of environmental protection, more and more stricter to the regulation of noise, and for example transformer low noise of strong request Static Electro induction device.
Static Electro is responded to device by the Static Electro induction device main body with iron core and winding is placed in storage tank and is configured, and carries out voltage transformation and similar.By connecting electricity, iron core and the winding of Static Electro induction device main body are vibrated.Winding is connected the electromagnetic and mechanical force vibration in moment by electricity.When owing to being encouraged by winding while producing magnetostriction, iron core is vibrated.
The vibration of Static Electro induction device main body is transmitted to the storage tank around main body, and the vibration of the side surface of storage tank and radiation sound are to the periphery of storage tank, cause from Static Electro induction device generation noise.
In order to prevent that sound is from the radiation of Static Electro induction device, can consider that Static Electro is responded to device to be contained in by steel plate and the similar sound insulation building of making.But, in the method, the problem that exists erection space to increase.In addition, provide sound panel also can consider to the method for storage tank periphery.But, in the method, need to be designed to sound panel and can not vibrated by the vibration of storage tank outer surface.
Extremely low in order to realize noise in the situation that Static Electro induction device not being increased to structure, also take the measure of the vibratory output that reduces storage tank side surface.This can be that side surface that wherein reinforcement material is attached to storage tank is to provide the method for vibration to the node of storage tank side surface, in method, the size in plate region is set to and makes plate region not have the natural frequency near the main frequency component of vibration, and similar.
Here, the method for the vibration of reduction storage tank side surface is described with reference to Figure 20 and Figure 21.As seen in these figures, Static Electro induction device main body 10 is sealed in storage tank 20.Multiple reinforcement materials 61 are attached to the side surface of storage tank 20.Be reinforced material 61, the top and bottom of storage tank 20 side surfaces, the Shi Ban region, region 62 surrounding.Particularly, plate region 62 only represents the region being formed by the plate material that forms storage tank 20 self.
As mentioned above, traditionally, the sheet of multiple reinforcement materials 61 is attached to the side surface of storage tank 20, so that the node of vibration to the side surface of storage tank 20 to be provided, thereby reduces the amplitude of storage tank 20 side surfaces.In addition, set the size in plate region 62 by the position of adjustable rooting material 61, make plate region 62 not there is the natural frequency near the main frequency component of vibration, avoided causing due to resonance the expansion of vibration.
But in traditional Static Electro induction device, the reduction of noise can not realize fully.Particularly, the sheet of multiple reinforcement materials 61 is attached to the side surface of storage tank 20, and the position of reinforcement material 61 is set to the node of vibration.But self is formed the side surface of storage tank 20 continuously, and on the whole side surface of storage tank 20, inevitably produce vibration.The loudness of noise depends on the region of vibration, so if vibration produces on the whole side surface of storage tank 20, it is not enough that the reduction of noise becomes.
In addition, the size in plate region 62 is determined by the position of adjustable rooting material 61, makes plate region 62 not have the natural frequency of the main frequency component of contiguous vibration.But plate as above region 62 has makes its shape easily with natural frequency, and be difficult to make the natural frequency in all plates region 62 all to depart near the frequency of vibration main frequency.

Please note in the present embodiment, be provided with three attenuation parts 30, still, the quantity of parts can appropriate change.
In Fig. 3 and Fig. 4, each hard part 32 and each soft parts 33 are alternately stacking.But, replaced number arbitrary in stacking hard part 32 and soft parts 33 and must be not all the time one.For example, (or multiple) hard part 32 and multiple soft parts 33 also can be by alternately stacking.
Friction is formed on each hard part 32, and this contributes to the inhibition to vibration, so form the preferably big figure of number of the hard part 32 of stacked body 31.The number of hard part 32 can be set to 10 to 100, for example.

In addition, soft parts 33 can also have polytype fibrous member.For example, must can be used by a mixing packing material forming by carbon fiber and potassium titanate.By filling mixing packing material in PTFE, in temperature range, from room temperature to 333K, footprint pressure is 10MPa, and loading stress is in the situation of 2MPa, and it is possible obtaining 106 cycle-indexes or above shear fatigue intensity.
Box-like frame members 34 is formed by insulating material, and accommodating stacked body 31.By stacked body 31 is set in box-like frame members 34, can prevent that in transportation and assembling the position of hard part 32 and soft parts 33 from moving when attenuation part 30, can workability thereby improve.In addition,, by using the material of insulating material as box-like frame members 34, can obtain hard part 32(metallic plate, electrical insulation capability for example).
In the present embodiment, Static Electro induction device main body 10 is placed in storage tank 20 by the attenuation part 30 being arranged between lower web 16b and base plate 22.Vibration is only undertaken by attenuation part 30 to the propagation of base plate 22 from Static Electro induction device main body 10.Utilize said structure, two operations that vibration provides to propagating through of base plate 22 attenuation part 30 described below from Static Electro induction device main body 10 and being inhibited.
The first operation is the reduction of the vibration that realizes by vibration isolation.The reduction of vibration can realize by the spring-mass damping system as single-mode system.Due to the electromagnetic and mechanical power producing in winding 12, and at shank 11, the magnetostrictive force producing in the upper yoke 13a of portion and the lower yoke 13b of portion, exciting force F
oin Static Electro induction device main body 10, produce.At exciting force F
ounder effect, the power that is delivered to base plate 22 by attenuation part 30 is set to power F.At this moment, power is responded to the Representation Equation of device main body 10 below the transmissibility γ of base plate 22 can use from Static Electro.
Here ζ (=(c/2) (mk),
1/2) representing that attenuation coefficient, m represent the quality of Static Electro induction device main body 10, k represents the spring constant of attenuation part 30, and c represents the attenuation constant of attenuation part 30, and ν (=f/fn) represents frequency ratio, and fn(=1/ (2 π) is (k/m)
1/2) represent natural frequency, and f represents exciting force F
ofrequency.
If the transmissibility γ of power is 1 or following, the power that is passed to base plate 22 from Static Electro induction device main body 10 is reduced.For this reason, in frequency ratio be
or in above scope, transmissibility γ becomes 1 or following, causes vibration to be lowered.Owing to thering is electromagnetic and mechanical power and magnetostrictive force, exciting force F in Static Electro induction device main body 10
ofrequency f be vibration fundamental frequency.In order to reduce vibration, need to meet " natural frequency
(more preferably, " natural frequency
).Need to determine material, thickness and the quantity of hard part 32 and soft parts 33, to meet above-mentioned relation formula.
Please note that spring constant k changes according to the pressure (quality of Static Electro induction device main body 10) that is applied to attenuation part 30.Particularly, preferably pressure is very large to a certain extent, because spring constant k(attenuation coefficient ζ) take desired value.
Utilization is designed to meet the attenuation part 30 of above-mentioned condition, and vibration is suppressed to the propagation of base plate 22 from Static Electro induction device main body 10, causes the vibration of storage tank 20 to reduce, and namely, the reduction of noise can realize.
The second operation is because the vibration that the dissipation of energy in attenuation part 30 causes reduces.Because the frictional force producing between hard part 32 and soft parts 33, and due to the dissipation of energy causing that decay of the material in soft parts 33, it is suppressed to the propagation of base plate 22 that vibration is responded to device main body 10 from Static Electro.Therefore, the vibration of storage tank 20 is lowered, and the reduction of noise can realize.
As mentioned above, according to the present embodiment, by attenuation part 30 being clipped between Static Electro induction device main body 10 and base plate 22, the vibration of storage tank 20 is lowered, and reducing noise effect can realize.
In the present embodiment, do not need outside or the peripheral new construction that reduces noise that provides to storage tank 20, this also makes cost.Particularly, the reduction of noise can realize by attenuation part 30 being arranged between interior subordinate's web 16b of storage tank 20 and base plate 22.
In addition, in the present embodiment, because attenuation part 30 is sandwiched between Static Electro induction device main body 10 and base plate 22, the pressure being applied on each attenuation part 30 is increased, make the spring constant k(attenuation coefficient ζ of each attenuation part 30) take appropriate value, this is favourable.

Fig. 5 and Fig. 6 are respectively according to transparent front view and the transparent side view of the Static Electro induction device of modified example 1.
In modified example 1, attenuation part 30 is sandwiched in (Static Electro induction device main body 10 is placed in storage tank 20 by attenuation part 30) between lower web 16b and base plate 22.About this point, modified example 1 is identical with the first embodiment.This modified example 1 is different from the first embodiment and is to provide floor-side reinforcement 50.Each floor-side reinforcement 50 is arranged on base plate 22 outsides in the position that attenuation part 30 is set, namely, and the position via base plate 22 facing to attenuation part 30.
By the position (at approximate same position) facing with each other via base plate 22 at attenuation part 30 and floor-side reinforcement 50, each attenuation part 30 and each floor-side reinforcement 50 are set, the rigidity of the lower surface of attenuation part 30 increases.Therefore, attenuation part 30 is prevented from and base plate 22 one vibrations.In addition, because the vibration of base plate 22 receiving attenuation parts 30 and vibration is turned back to attenuation part 30, so the dissipation of energy effect being provided by attenuation part 30 is further strengthened.
As mentioned above, in this modified example, by floor-side reinforcement 50 being set via base plate 22 facing to the position of attenuation part 30, it is possible that the Static Electro induction device that can further reduce noise is provided.
