SU512685A1 - Method for controlling the state of variable magnets of magnetically controlled contacts of multiple coordinate connections - Google Patents

Description

Due to the fact that the proposed control method does not change the state of alternating magnets at a time of only one DC signal, along the coordinate with the ethnm signal it is possible to combine several connectors and, thus, the formation of a macromatrix, i.e. transfer to position "1 lu: combat" the number of switching points without changing the position of the rest. This property of the proposed method extends the use of connectors (for example, in control circuits) and simplifies the control circuit of connectors.

FIG. 1 turns out to be closed (the position of "I - Fig. 1, a) and open (the position of" O - Fig. 1.5) of the state of Magnetically controlled contacts, which are determined by the direction of the magnetization vectors of non-magnetic: magnetically magnetic (Hx) and (well); in fig. : 2- connector scheme; “And FIG. 3 - harakteristiki magnetizing variable magnet; in fig. 4 - possible waveforms; in fig. 5 - directions of vectors of constant (B) and variable (B) magnetizing fields, for coaxial zeros; in fig. 6 - the same for orthogonal fields.

The connector contains a coordinate winding / - /, but which passes, for example, a ground current signal; coordinate winding 2-2, software which flows, for example, the signal alternating current; magneto-guided Pin 3, which is triggered by magnetizing the timeless magnet; alternating magnet 4.

The characteristic of magnetization at the supply of one signal of direct current is shown by curve 5 (Fig. 3); magnetization characteristic when simultaneously applied signals of DC and AC currents - curve 6, the magnetic force at the selected operating point - point 7.

The method of controlling the multiple coordinate connector is that the coordinate winding / - / is given a signal of constant current at the coordinate X 8, and the coordinate winding 2-2 gives a signal of decreasing but amplitude of the alternating current at the coordinate Y 9 and the point where the two coordinate windings intersect, the magnetisation of the non-magnet magnet occurs on curve 6, and the magnetically controlled contact 3 is activated.

At all other points of the X coordinate, magnetization occurs on curve 5, and with an appropriate choice of the magnetomotive force FP, the state of the variable magnet will not change. In all the other points of the Y coordinates, demagnetization of the previously magnetized matnit variables occurs.

Since the most convenient way to create a matrix is the orthogonal placement of integral coordinate windings, the proposed method of controlling the field makes it possible to magnetize the variable magnet with mutually perpendicular fields, which can simplify the design of the connector.
