SU553633A1 - Functional Transformer-to-Electrical Transducer - Google Patents

Description

Kam 4 of non-magnetic electrically conductive material, the racks are installed parallel to each other between the pole rods of the magnetic circuit; insulating plates 5 with flat functional circuits, which are located and move in the gaps between the plates 3 and the poles of the magnetic circuit 1, fastener parts 6, structural part 7 with grooves guiding the moving plates with flat contours.

The introduction of magnetic plates 3 allows not only to increase the quality of the magnetic field in the gaps, but also to realize an effective reduction in the total air gap of the transducer, since the height of the mounting parts of the plates with contours does not affect, in contrast to the design with a single gap, the total value air gap.

The number of plates 3, i.e. the number of gaps is chosen based on functional tasks and design considerations. Racks 4 can be installed both in the openings of the magnetic conductor and on the outer sides (Fig. 2), and in the second case they should have openings for plates with flat contours, in the first case openings are optional. It is possible to use four plates of posts 4, this increases the uniformity of the distribution of polch in the gap and reduces the scattering flows both along the axis of movement X and along the axis of the function f. (X). Denote the height of each of the gaps 5.

Then the total, total air gap, designed to accommodate plates with flat contours, is equal to:

D (n + 1) b, (1)

where n is the number of psychplast magnet magnet 3. At the same time, in each of the gaps of kaotine, the distribution of the magnetic field corresponds exactly to the height of the gap, and since

A 2

This field is ziachitivnuyu coordinates more equal to that which would have occurred with a single gap A and the same dimensions of the poles and agiitoprovodano axis Xi f (x).

Similarly, it can be argued that the relative magnitude and influence of the flux of the scattering will be equal to (2), significantly lower in this converter with gaps b, than in the gap gap A.

Newly introduced magitite psie plates 3

condense, focus the magnetic flux in the coordinates of the working gap.

This effect is further enhanced by the plate racks 4, which also significantly reduce scattered fluxes from the ends and edges of the poles of the magnetic circuit 1 and plate 3, and scattered fluxes of winding sections 2 through loops through the poles and intermediate plates 3, playing the role of screens for the indicated flows.

Thus, the efficiency of the device consists in expanding the functionality and accuracy of a transformer converter moving into an electrical signal by increasing the uniformity of the magnetic flux of the working gap and the scattering fluxes with increasing number of plates with functional circuits located in the gaps of the transformer converter.

kpoMe, as shown above, can be obtained by reducing the total air gap of the transducer, reducing the required number of ampere excitation turns.
