Description of the Invention: [Technical Field] The present invention relates to a stationary induction appliance, and more particularly to a static induction appliance having vibration insulation performance and noise reduction performance. [Prior Art] In recent years, based on the viewpoint of environmental protection, noise has become increasingly strict, and the noise reduction of static induction appliances such as transformers has been highly anticipated. The noise of the stationary induction device is generated by the vibration of the body of the stationary induction device propagating toward the sump, causing the side of the sump to vibrate to diverge the sound to the surroundings. As a machine # for preventing the spread of such a divergent sound, a method of accommodating a static induction electric appliance in a soundproof building made of an iron plate or the like is considered. Since the above method has a problem that the installation area is increased, it is widely practiced to directly arrange the baffle around the sump. The baffle is a reduction effect when the sound penetrates the baffle, that is, the sound that is diverged from the side of the sump is reduced by the penetration loss. This soundproofing countermeasure is based on the vibration of the side surface of the sump to vibrate the sound insulating panel itself, and the noise is not generated. (For example, refer to the patent literature.) The following 'refer to Figs. 6 to 9' As shown in Fig. 16, the stationary induction electric appliance main body 1 is housed in the storage tank 2. The storage tank 2 is slid on the foundation 6. The storage tank 2 is welded to the upper side of the four sides. And 卩' are respectively joined with a cross-sectional mouth-shaped upper reinforcing beam 161 and a lower reinforcing beam 162 in the horizontal direction. 155051.doc 201207872 In the upper reinforcing beam 16, the upper end surface is mounted with the upper support point 17, on the other hand a lower portion of the outer side surface 3 of the sump located below the lower reinforcing beam 162, and a lower supporting point 18' is installed between the upper supporting point 17 and the lower supporting point 18 to cover the outer side surface 3 of the sump The seesaw 5a includes a baffle body (insulation panel) 22, elastic members 23 and 24, and sealing materials 25 and 26. As shown in Fig. 17, the baffle body 22 itself includes a rectangular plate 19 and is mounted on The frame-shaped reinforcing ribs 2 of the periphery of the flat plate 19 and the reinforcing ribs 21 of the cross shape, the flat plate 19, the reinforcing ribs 20, and the reinforcing ribs 21 are disposed on the baffle body 22 and the upper support point by the welded joint 0. The elastic element 24 is disposed between the baffle body 22 and the lower support point. The sealing materials 25 and 26 have flexibility and are provided with elastic elements 23 and 24, thereby being sealed to the baffle body 22 and the sump. A gap created between the side faces 3. In the prior art which contemplates the soundproofing countermeasures as described above, the baffle "has a sound that is dissipated from the outer side 3 of the sump by the penetration loss. At the same time 'to reduce the noise from the baffle 5a The generation of the noise itself increases the bending rigidity of the baffle body 22 by the reinforcing ribs 20, 21', thereby preventing the flexural vibration of the baffle body 22, and the elastic elements 23 and 24 and the baffle body 22 are included. The vibrating system is close to the ideal degree. Therefore, the vibration insulating effect by the elastic members 23 and 24 is improved, and the vibration of the baffle body η is suppressed, so that the sound emitted by the baffle body 22 can be reduced. Further, by providing the elastic elements 23 and 24, a gap is formed between the center of the sound insulating plate and the outer side surface 3 of the groove, but it can be prevented from the outer side of the sump by the soft sealing material 25: 155051.doc 201207872 26 The sound of the divergence leaks from the space inside the baffle plate 5a to the outside through the gap. Further, the baffle plate body 22 is formed of the vibration-damping plate, and the vibration-damping effect of the baffle plate can be improved. The high-knife viscoelastic material is sandwiched between a plurality of steel sheets, and the body is molded to have a high damping ability for vibration. Further, as shown in Fig. 18, three soundproof plates 5a are proposed to be attached to the outer side surface 3 of the tank. By using the plurality of divided baffles 5a in this manner, one baffle 5a can be miniaturized, which facilitates manufacturing and transportation. Further, as shown in Fig. 19, it has been proposed to attach a sound absorbing material 14 including glass wool or the like to the inner wall of the baffle body 22. By using the sound absorbing material 14 in this way, since the noise level caused by the standing wave 27 shown in the figure can be reduced, and the noise level of the space inside the sound insulating board 5a is lowered, the sound of the sound insulating board body 22 can be further reduced. Or the sound that leaks through the sealing materials 25 and 26. [Patent Document 1] [Patent Document 1] Japanese Patent Laid-Open Publication No. Hei No. Hei 10 149 920 [Description of the Invention] [Problems to be Solved by the Invention] However, a static induction electric appliance using a sound insulating plate is used as a sound insulation as described in the above. The countermeasures will have the following problems. That is, in the prior art shown in Fig. 16, the baffle body 22 which is resistant to f rigidity is reinforced by the reinforcing ribs 2 and 2, and the elastic members 23 and 24 constitute the anti-vibration support 'from the outer side 3 of the sump Exciting vibration. It is equivalent to the vibration system of the continuum of the elastic branch building. It is the same as the case of the 丨 丨 degree of freedom system 15505 丨.doc 201207872. The lower the natural vibration number calculated according to the mass and the spring constant, the vibration insulation relative to the input. The higher the performance of the nature. Therefore, in order to optimize the vibration suppression, it is preferable to soften the elastic supports 23 and 24, and to lower the natural vibration number of the baffle 5a. At the same time, however, the natural vibration number of the baffle 5& will be close to the frequency region of the maximum amplitude of the earthquake, and if the natural vibration number is set lower, the response of the baffle body 22 to the seismic input will increase, and The possibility of causing excessive vibration. If the vibration suppression is optimized in this way, the shock resistance of the baffle 53 is lowered. Moreover, in the prior art shown in FIG. 18, if the number of blocks of the baffle plate is increased, the support point 7 and the lower support point 18, the elastic elements 23, 24, and the sealing material are provided on the outer side surface 3 of the sump. Parts such as 25, 26, etc. also need to be added. Further, in the case where a flange or a pipe is disposed on the outer side surface 3 of the sump, whether or not the upper and lower support points 17 and 18 are disposed at an optimum position, or a member having a complicated shape is required. Furthermore, due to the assembly error, the positions of the baffle body 22, the upper branch point, and the lower-P branch point 18 may be mutually offset. Since the position and the interval of the gap are different for each of the baffles 5a, Therefore, it is not easy to install the sealing materials 25 and 26» so that if the number of the baffles & is increased, the number of fabrications will increase. Further, in the prior art shown in Figs. 16 to 19, since the upper reinforcing beam 1 and the surface of the outer side surface 3 of the sump are attached, the upper branch point 17 and the lower support point 18 are installed over the entire length of the sump, and at " The surface of the support point of Hai # is installed with the baffle body 22 via the elastic elements 23, 24, so there are many parts, and it costs a lot of 15505 丨.doc 201207872 installation work. That is, it is difficult to specify the mounting range of the baffle 5a in accordance with the noise mode. Further, since the baffle body 22 is attached via the elastic members 23, 24, it is difficult to mount the weight supporting members on the surface of the baffle body 22, resulting in a complicated construction of the supporting members for mounting the weight supporting members. In addition, in the case where a structure such as a cover, an oil pipe, or a manhole is provided in the vicinity of the sound insulating plate mounting position, there is a problem that the machine body cannot be miniaturized because a gap is not provided in the sound insulating plate 5a. Therefore, the present invention has been made in order to solve the problems of the prior art as described above. The object of the present invention is to provide a static induction electric appliance having a small number of fabrications and having high vibration insulation performance and noise reduction performance. [Technical means for solving the problem] In order to achieve the above object, the static induction device of the present invention is characterized in that it comprises a storage tank for accommodating the body of the stationary induction device, and is external to the storage tank with respect to the outer side of the storage tank. a sump reinforcing member fixed in a manner of forming a plurality of ridges in a downward direction or a lateral direction; a sump reinforcing rib for joining the sump reinforcing members to each other; and splicing to cover the swell reinforcing member and the sump reinforcing rib The sound insulating panel installed in the space portion; the sound insulating panel includes two or more sound insulating plates facing each other, and is disposed so as to form a sealed space between the sound insulating plates, and the angle between the adjacent sides is relatively large In the case of an angular shape, the polygonal frame-shaped reinforcing ribs are installed with an angle of inclination of 4 degrees or more.

Since the opening portion of the concave space portion is attached with the sound insulating panel by direct attachment welding, a sufficient vibration reducing effect can be obtained, and since the foundation for the sound insulating panel is not required, the mounting becomes easy, and the number of manufacturing works can be reduced. Or production costs. In addition, the "insulation panel can be freely changed in accordance with the vibration and noise modes" to obtain the most suitable structure for the noise mode and low-cost static induction appliances. [Complex Mode] Hereinafter, an embodiment of the static induction motor of the present invention will be described with reference to the drawings. In the drawings, the same reference numerals are given to the same parts, and the repeated description is omitted as appropriate. [Embodiment 1] Hereinafter, a stationary induction motor according to this embodiment will be described with reference to Figs. 1 to 5 . 1 is a perspective side view of the static induction device of the present embodiment, FIG. 2 is a front view of the arrow II direction of FIG. 1, and FIG. 3 is a plan view of the arrow m direction of FIG. 2, and FIG. 4 and FIG. 5 are respectively in the embodiment. Front and side views of the soundproof panel used. (Configuration) In Fig. 1 and Fig. 2, the static induction electric appliance of the present embodiment has a static induction electric appliance body 1 including a core and a winding wire, and is sealed with an insulating medium such as insulating oil or insulating gas to form a horizontally long one. The cuboid tank 2 is located inside the 155051.doc 201207872 and is placed on the foundation 6. 2 and FIG. 3, a plurality of ridges are formed in the vertical direction with respect to the outer side surface 3 of the old tank having a wide width relative to the four outer side faces 3 of the storage tank 2 (hereinafter referred to as the outer side surface 3 of the sump). In the transverse direction, a plurality of (4l, 2, 43 and 44) sump reinforcing members 4 having a quadrangular or square-shaped cross section are juxtaposed in the lateral direction, and the sump is reinforced by the outer side 3 of the Benin trough by refining. The members 4, 42, 43, and 44 are so as to cause the outer side surface 3 of the sump to alternately form ridges formed by the sump reinforcing members 41, 42, 43 and 44 in the lateral direction, and the concave space portions 81, 8 and 83 0 The sump reinforcing members 41, 42, 43, and 44 are joined to each other, and the concave spaces 81 are divided into three in the vertical direction, and two slabs of substantially parallel plates are attached to the foundation 6 by welding or the like. The reinforcing ribs 7" and 7丨2, similarly, two sump reinforcing ribs 72 and 722 are attached by welding to the concave space portion h, and two sump reinforcing ribs 73 1 and 732 are attached by welding equal to the concave space portion h. The welded portion in this case is a portion where the three sides of the sump reinforcing rib 7 meet in the concave space portion 8, i.e., both side faces of the sump reinforcing member 4, and the sump outer side surface 3 surrounded by the side surface. In addition, in FIG. 2, although the state in which two sump reinforcement ribs 7 are attached is shown in each recessed space part 8, the sump reinforcement rib 7 is not limited to two, and may be three or more (73 ... 7n). Thus, the concave-shaped space portions 8i, 82, and the groove-forming reinforcing ribs 7 formed in the upper-lower direction between the sump reinforcing members 4i and the cores 43 and 44 which form the "up and down direction ridges" are provided with appropriate thickness. The soundproof panel is covered with the opening portion of the concave space portion 8 by directly attaching and splicing, and the sound insulating panel is mounted on the sump 155051.doc 201207872 cores, 42, 43 and 44 and the sump reinforcing ribs 7, 72 5 peripheral parts. As shown in FIG. 4 and FIG. 5, the sound insulating panel 5 includes a pair of opposite sound insulating plates 5a and a sound insulating plate 5b; and a four-side band shape formed between the sound insulating plates 5a and the sound insulating plates 5b to form a sealed space 9. Frame-shaped reinforcing ribs 5c composed of reinforcing ribs 5Cl, 5c2, 5c3, and 5c4; and cross-shaped reinforcing ribs 5d disposed inside the frame-shaped reinforcing ribs 5c. Further, the pair of baffles 5a, 5b' of the frame-shaped reinforcing ribs 5c and the cross-shaped reinforcing ribs 5d are all made of an iron plate, and the respective contact portions are fixed by welding. Since the pair of baffles 5a and baffles 5b are slightly fused by the cross-shaped ribs 5, vibration can be suppressed. Further, since the soundproof panel 5 is usually produced in the atmosphere, air is introduced into the sealed space 9. As shown in FIG. 3, the sound-insulating panel 5 thus produced is attached so that the frame-shaped reinforcing ribs and the sound insulating plates 5& are hidden in the concave space portion, so that the sound insulating plate 5a is longitudinally retained. And the lateral dimension is selected to be smaller than the baffle 5b by the portion corresponding to the welded portion.

Fine ingot β d 201207872 Strong rib 5 (^ and 5 < ^, reinforcing rib 5 (^ and 5 (: 4 into a non-parallel relationship. Again, in Figure 4, the box The reinforcing ribs 9 are formed in a quadrangular shape and are formed by four-sided reinforcing ribs. However, in the case of a frame having a shape of five or more, they are formed by reinforcing ribs of five or more sides. (Action) Thus, by forming a plurality of ridges in the lateral direction The sump reinforcing members 41, 42, 43 and 44 attached to the outer side surface 3 of the sump and the sump reinforcing ribs 72, 7n cover the sound insulating panel 5 formed on the concave space portion 8 of the outer side surface 3 of the sump, according to The vibration and noise mode of the static induction appliance can freely change the number of installation blocks or the installation range. Since the soundproof panel 5 is composed of iron plates, it is cheaper and is covered by the sump by direct attachment welding. Since the members 4, 42 and the core and the surface of the concave space portion 8 surrounded by the sump reinforcing ribs 7!, 72 are attached to the surface of the concave space portion 8, the sound insulating panel 5 is attached, so that the mounting work is easy. Moreover, since the sound insulating panel 5 is welded Firmly mounted on the outer side of the tank 3, so oil storage The weight support member such as the radiator frame and the casing cover is directly attached to the surface of the sound insulating panel 5, so that the structure of the support member can be simplified. Further, the structure of the cover, the oil pipe, and the like must be set. In the case of the vicinity of the mounting position of the soundproof panel 5, the sound insulating panel 5 can be installed to provide a notch in advance in the sound insulating panel 5, thereby easily arranging the structure. Further, due to the opposite soundproofing plates 5 & The plates are formed in a sealed space with each other, so that the sound insulation performance of the sound penetrating the sound insulating panel 5 can be improved. In the case where the two soundproof plates 5a, 5b are opposed to each other in a sealed space, the sound insulation 155051.doc 201207872 panel 5 is formed. It is possible to obtain a higher sound insulation effect than the one-layer baffle (i.e., the same-quality baffle) which is equal to the thickness of the two plates. The reason is that an intermediate layer is formed between the two baffles 5a and 5b. The medium which becomes the resistance when the sound energy is input to the sound insulating panel 5 (that is, the difference in impedance between the sound insulating panels 5) can be effectively used. Further, since the four side reinforcing ribs constituting the frame reinforcing ribs, 5C2, C3 and 5 C4 The mounting angle is inclined by more than 4 degrees with respect to the case of the regular square shape, so that the resonance of the sound in the sealed space 9 can be prevented. The noise generated by the stationary induction appliance is usually the problem of the frequency ι Hz to 500. The noise of 1^ has a half-wavelength of 34〇111111 to 17〇〇11^. The resonance of the sonar is generated in a direction in which an integral multiple of a half wavelength of a sound considered to be problematic is substantially equal to each dimension of the sealed space 9. In the case where the sound is resonated in the sealed space 9, the sound attenuated by the sound insulating panel 5 can be amplified again, and the sound insulating performance is lowered. Further, due to the closed space 9 formed between the opposing sound insulating plate 5a and the sound insulating plate 5b The cross-shaped reinforcing rib 5d is welded to the surface of the sound insulating plate 5& and the crucible, so that both the vibration reducing effect and the sound insulating performance of the surface of the sound insulating panel 5 can be obtained. Here, the frame-shaped reinforcing rib is a polygonal shape, and the cross-shaped reinforcing rib includes: a second reinforcing rib provided in a manner from a point of the edge of the frame-shaped reinforcing rib to an opposite side or vertex; The second reinforcing rib provided in the vicinity of the midpoint of the first reinforcing rib so as to intersect with it. Further, both the first reinforcing rib and the second reinforcing rib are attached so as not to be parallel with any one of the frame-shaped reinforcing ribs. (Effects) As described above, according to the first embodiment, a plurality of sump reinforcing members are juxtaposed and fixed in the lateral direction with respect to the outer side surface of the sump 3 155051.doc 12 201207872, and the sump reinforcing members are joined to each other by the sump reinforcing ribs. And #u attaching and splicing, and installing an acoustic panel on the opening of the space portion including the side of the sump, the sump reinforcing member and the sump reinforcing rib, so that sufficient vibration reduction effect can be obtained, and since it is not required to be installed for soundproofing The basis of the panel makes the installation work easy, so the number of productions or the manufacturing cost can be reduced. In addition, the sound-insulating panel can freely change the mounting range according to the mode of vibration and noise, so that the most suitable structure and low-cost static induction electric appliance can be obtained in response to the noise mode. Further, since the sound insulating panel is attached to the sump reinforcing member by direct welding so as to cover the concave space portion formed between the sump reinforcing members, a weight can be attached to the surface of the sound insulating panel (storage tank, heat sink) The gantry, casing cover, etc., the result 'can make the machine miniaturized. Further, since the female fitting angle ' of the reinforcing ribs constituting each side of the polygonal frame-shaped reinforcing rib is inclined by 4 degrees or more with respect to the case of the regular polygonal shape, the resonance of the sound in the sealed space can be lowered. To the extent that it will not become a practical problem, the sound insulation performance is further improved, thereby providing a static induction electric appliance having a low number of fabrications and a low cost, and having a reduced vibration effect and a high sound insulation effect. [Embodiment 2] Hereinafter, a stationary induction electric appliance according to Embodiment 2 will be described with reference to Fig. 6'. Fig. 6 is a perspective side view of the sound insulating panel 5 employed in the present embodiment 2. As shown in Fig. 6, the sound insulating panel 5 used in the second embodiment is sealed between a pair of the sound insulating plates 5a and the sound insulating plates 5b and the frame reinforcing ribs 5c as opposed to 155051.doc • 13 to 201207872. The space 9 is set to a vacuum state. The shape of the frame-shaped reinforcing ribs itself is the same as that of Fig. 4 of the first embodiment. By keeping the inside of the sealed space 9 of the sound insulating panel 5 in a vacuum state, the propagation of sound in the sealed space 9 is eliminated, and the soundproofing effect is increased by the penetration loss. Therefore, the sound insulating effect can be expected to be further improved as compared with the first embodiment. As described above, according to the second embodiment, it is possible to suppress the propagation of sound in the sealed space by keeping the inside of the sealed space 9 in a vacuum, thereby providing a static induction electric appliance having a higher sound insulation effect. [Embodiment 3] Hereinafter, a stationary induction electric appliance according to Embodiment 3 will be described with reference to Fig. 7 . Fig. 7 is a perspective side view of the sound insulating panel 5 used in the third embodiment. As shown in Fig. 7, the sound insulating panel 5 used in the third embodiment is in a vacuum state in a sealed space 9 in which a pair of opposite sound insulating plates 5a and a sound insulating plate and a frame reinforcing rib are formed. Further, a vacuum valve 1 is attached to the outer surface of the sound insulating plate 5b constituting the sealed space 9. In the case where the degree of vacuum in the sealed space 9 of the sound insulating panel 5 is lowered after the long-term operation of the stationary induction device, the sound insulation performance is lowered. Therefore, in the third embodiment, the vacuum can be communicated with the sealed space 9 of the soundproof panel 5. A pressure gauge (not shown) is attached to the valve 1 , and the pressure in the sealed space 9 is confirmed by the pressure gauge. When the degree of vacuum is lowered, the vacuum pump is connected to the vacuum (7), so that the sealed space 9 is again kept good. Vacuum state. As described above, according to the third embodiment, the vacuum valve can be installed by the soundproof panel surface 155051.doc 201207872 to maintain and monitor the degree of vacuum in the sealed space of the sound insulating panel after the sound insulating panel is mounted, thereby providing a high quality for a long period of time. Static induction appliances with high reliability and sound insulation. [Embodiment 4] Hereinafter, a stationary induction electric appliance according to Embodiment 4 will be described with reference to Fig. 8 . Fig. 8 is a perspective side view of the sound insulating panel 5 employed in the present embodiment. As shown in Fig. 8, the sound insulating panel 5 used in the present embodiment 4 is a vacuum in the sealed space 9 formed between the pair of the sound insulating plates 5a and the sound insulating plates 5b and the frame reinforcing ribs 5c. In the state, the vacuum check valve 11 that communicates with the sealed space 9 is attached to the outer surface of the sound insulating plate 5b constituting the sealed space 9. In this way, by installing the vacuum check valve u on the surface of the sound insulating panel 5, the sealed space in the sound insulating panel can be easily kept in a vacuum, and since the mounting area is more suppressed than the vacuum valve, it can be soundproofed. The surface of the board simplifies the support structure of the heavy objects (storage tank, radiator rack, casing cover, etc.) and reduces the manufacturing cost. As described above, according to the fourth embodiment, the vacuum check valve 11' can be used to effectively utilize the space of the surface of the baffle plate, so that the vacuum valve can be used more inexpensively, thereby providing a manufacturing cost. The static induction electric appliance with the advantages of reduction, miniaturization of the machine and excellent sound insulation performance. [Embodiment 5] Hereinafter, a stationary induction electric appliance according to Embodiment 5 will be described with reference to Fig. 9'. Figure 9 is a perspective side view of the acoustic panel used in the present embodiment. The sound insulating panel 5 used in the fifth embodiment is closed as shown in Fig. 9 and is formed by 155051.doc 15 201207872, which is formed between the sound insulating plate 5a and the sound insulating plate, and the frame reinforcing ribs & The space 9 is in a vacuum state, and the vacuum pipe 12 that communicates with the sealed space 9 is attached to the outer surface of the sound insulating plate 5b constituting the sealed space 9, and the sound insulating panel 5 is connected to the vacuum pipe 12, and Figure 7 shows the link. As described above, according to the fifth embodiment, the vacuum pipe can be used to mount the vacuum pipe 12 on the surface, and the vacuum operation can be performed once in the sealed space 9 of the plurality of sound insulating panels, thereby providing a static induction that is easy to perform vacuum work. Electrical appliances. [Embodiment 6] Hereinafter, a stationary induction device according to Embodiment 6 will be described with reference to Figs. 12 and 13 . Fig. 12 is a front elevational view showing the sound insulating panel of the sixth embodiment, and is a side view. In the sound insulating panel 5 used in the sixth embodiment, the sound insulating panel 5 shown in Fig. 4 is used as a base, and the sandwich type vibration damping plate 13 is attached to the sealed space 9. In other words, as shown in FIG. 12 and the circle 13, the inner surface of the sound insulating plate 5b on the surface side of the sound insulating panel 5 is sandwiched by a combination of an aluminum restraint plate and a sticky layer having the properties of both rubber and clay. Layered damping plate 13. In this way, since the sandwich-shaped damper plate 13 in which the aluminum plate and the adhesive layer are combined is mounted on the inner surface of the baffle 5b, since the deflection of the two steel plates is retarded when the vibration is transmitted, the viscous portion is located therebetween. The elastic resin generates a shearing force, which causes the vibration energy to be absorbed and changed into heat energy, and reduces the emission of sound caused by the vibration of the surface of the sound insulating panel 5. As described above, according to the sixth embodiment, the sound-insulating panel 5 can be reinforced by the sandwich-shaped vibration-damping plate u of the sound-insulating plate 155051.doc -16-201207872 plate 5b on the surface side. The vibration-reducing effect of the surface of the baffle plate is such that the sound-insulating performance of the baffle panel 5 is greatly improved. Since the sandwich-shaped damper plate 13 can be obtained at a very low price, it is possible to provide a static induction electric appliance which is low in cost and excellent in sound insulation performance. [Embodiment 7] Hereinafter, a stationary induction electric appliance according to Embodiment 7 will be described with reference to Fig. 14'. Fig. 14 is a perspective side view showing the sound insulating panel used in the seventh embodiment. As shown in FIG. 4, the sound insulating panel 5 of the present embodiment 7 is filled with a sound absorbing material 14 in a sealed space 9 formed by facing the sound insulating plate 5a, the sound insulating plate, and the frame reinforcing rib. The sound of the sound absorbing material 14 entering the sealed space 9 is absorbed by the sound energy inside the sound absorbing material 14 without penetrating the sound insulating plate 5b. As described above, according to the seventh embodiment, since the sound absorbing material 14 is filled in the sealed space 9 of the sound insulating panel, the sound entering the sealed space 9 is absorbed in the sound absorbing material 14 so that the sound is not worn. through. The sound absorbing material itself is inexpensive, easy to obtain, long in life, and not suitable for use. It can provide a static induction appliance with reduced number of productions and high sound insulation effect. [Embodiment 8] Hereinafter, a stationary induction electric appliance according to Embodiment 8 will be described with reference to Fig. 15 . Fig. 15 is a perspective side view of the sound insulating panel used in the present embodiment. The sound insulating panel 5 used in the eighth embodiment is as shown in Fig. 15, and is disposed in a sealed space 9 formed by a pair of the sound insulating plate 5a, the sound insulating plate 5b, and the frame reinforcing rib 5c which are opposed to each other at 155051.doc 17 201207872. Filled with liquid 丨5. As shown in the embodiment, the sound insulating panel 5 of the eighth embodiment has a larger attenuation of sound than a gas (air) enclosed in the sealed space 9. Moreover, there is a sound source with a large audio output in the liquid, and even if a sound having a high level is present, since the difference between the inherent acoustic resistance of the air and the liquid is large, the sound is almost completely reflected at the contact surface thereof, and is hardly directed to the air. It is emitted in the middle, so it will not become a loud noise level that makes people who are in the air bored. As described above, according to the eighth embodiment, the liquid enclosed in the sealed space 9 of the sound insulating panel 5 has sound transmission in a substance having a relatively large density, so that the liquid vibration requires a larger energy than the gas, and the sound is sounded. The attenuation is larger than in the air' to provide a static induction appliance with higher sound insulation. [Modification] In the above description, the sump reinforcing members 4 and 4 are widened in the vertical direction, and the sump reinforcing ribs 7 and 711 to 732 are set in the lateral direction, but the positional relationship between the two can be reversed. The sump reinforcing members 4, 4] to 44 are set in the lateral direction, and the sump reinforcing ribs 7, 7 丨丨 to 732 are set in the vertical direction.
