Description

The present invention relates to an alternating current electrical signaling device acting on an open wire using a transformer supplied with current from two or more points in order to replace the power nyHKTQB in the event of a broken wire with separate primary posts when the guard posts are connected in series.

On the iron core J superimposed primary, windings 2 to 3, fed from point A through resistance 5 and from point B through resistance 5, connected in opposite direction, with the magnetic flux of winding 3 approximately twice the magnetic flux of winding 2, so that winding current 4 is the difference between the currents, c6 produced by the coils of coils 5 and 2, winding 4 feeds the primary winding 5-P of the transformer with core 7, the secondary winding / 5 - J6 of which is closed to signal devices 20 and 2L

Parts 8 and 9 of the primary winding are opposite and have an equal number of turns, with the current flowing through the wire J2 through the winding P, through the resistance / j from one side, from the other through the winding 8 and resistance //.

Resistance 11 w. 13 serve to equalize the winding resistance and limit the amperage.

Turning off one of the switches / entails an imbalance in the magnetic fluxes of the coils 5 and P (due to the absence of voltage on the latter), the coil 8 creates a magnetic flux in the core, resulting in a current in the coils 15 and 16 connected by wires 17, 18 vi / Р with call 20 and beep 2 /.

The subject matter of the invention.

An alternating current electrical signaling device acting on a wire break characterized by the use of a transformer with current supplied from two or more points by two separate primary windings 2-5 superimposed on an iron core /, and (switched on oppositely, ampere turns of one of which windings Prevail over amperages another, the secondary winding of which transformer is included in two or

more opposing each other

servo-R windings, wound: on the iron core 7 and calculated so that their actions on the secondary winding J5-JJ6 connected in circuits from the ignition devices are mutually destroyed, when the same winding I disconnects in the signal circuit, the secondary-winding under the influence of another primary winding 5 is induced by a current driving the signal devices.
