摘要： The invention relates to a high- or medium-voltage electrical device (1) including an active induction portion (4), a vessel (3) surrounding the active portion and filled with a dielectric fluid, such as oil, and passive means (2, 20) for reducing the noise of the waves originating from the active portion and propagated in the dielectric fluid. According to the invention, the passive means create an interference field by dividing the propagated waves into two wave groups (01, 02) of opposite phase from one another in an area distant from the walls of the vessel so as to at least limit the amplitude thereof prior to contact therewith. The invention is an effective solution for significantly reducing the part of the noise propagated by the dielectric fluid medium.

摘要： The present invention relates to a sound-insulating device for a stationary induction machine with an active part, an insulating fluid surrounding the active part, and a tank enclosing the insulating fluid. The sound-absorbing device comprises a gas-filled cavity (1) and a resilient membrane (2, 3) surrounding the gas-filled cavity, thus obtaining a sound-insulating device which is extremely compressible. In the induction machine, the device is arranged between the active part and the tank of the induction machine and spaced from the inside of the tank. The sound-insulating device preferably has an extent in one plane, whereby the device has a membrane portion (2) facing the active part and a membrane portion (3) facing the tank. Preferably, at least one of the membrane portions has at least one corrugated region (8), and a spacing membrane (12) is arranged in the cavity (1) making contact with the membrane portion (2, 3) at at least two points.

摘要： An electric noise absorber for preventing looseness of magnetic body parts in a closed housing, without increasing the number of parts or decreasing the strength of the housing. The housing comprises a pair of case halves which house ferrite core halves, respectively, and are hinged to each other. The bottom wall of each case half is formed with a curved shape convex toward the space housing the ferrite core half. When the case halves are closed with the ferrite cores therein, the ferrite cores press each other toward respective bottom walls and resiliently deform the walls. The resilience of the deformed bottom walls urges abutting surfaces of the ferrite cores into close contact.

摘要： This invention relates to a line filter, which restricts magnetic influences of a leakage flux from a closed magnetic circuit core on other components and restricts entry of noise to the closed magnetic circuit core. The line filter comprises a synthetic resin bobbin (5) having flanges (2) at both ends thereof and a through-hole (20) formed in an axial direction, a square-shaped closed magnetic circuit core inserted into the through-hole (20) formed at the center axis of the bobbin (5), a winding (6) so wound between both flanges (2) of the bobbin (5) as to orthogonally cross the axial direction, metal terminals (9) planted to the flanges (6) and connected to the winding (6), and rotation prevention means for preventing the rotation of the closed magnetic circuit core (1).

摘要： A toroidal shaped transformer having two levels of structureborne noise isolation is disclosed. A 30-60 dB reduction in noise is achieved by isolation mounting the toroidal transformers (10) coaxially on a central support rod (30) which in turn is supported by an isolation mounted cradle (38). The isolation layers (32, 40) are made of compliant elastomeric foam rubber material.

摘要： An electromagnetic induction apparatus comprising a tank main body (3) having a bottom plate (32) and capable of being placed on a floor surface (9) and containing therein an electrical device (1) which vibrates during operation. The tank main body (3) is supported by supporting members (7) inserted between the tank bottom plate (32) and the floor surface (9) to define spaces (10) therebetween. A sound suppressing member (11, 12, 13, 14) is disposed in association with the space (10) defined between the support members (7) and between the tank bottom plate (32) and the floor surface (9). The sound suppressing member (11, 12, 13, 14) may be a sound barrier member (11) closing the space (10) defined between the tank bottom plate (32) and the floor surface (9) or a sound suppressing element (12, 13, 14) disposed within the space (10).
