PATENT TO INVENTION

DESCRIPTION

devices for wiring direct and alternating current.

To the patent of the in-ing company CiiMeMe and G pieckv (Siemens & Jlalske, Aetiengesellsehaft), in Berlin-Simenstadt, Germany, dated February 18, 1925 (for c.

The real inventors of In-ts. 1. Dupfmüppe p (I upfmuller) and N. Tspauzing (Arthur Clausing).

Priority of February 18, 1925 on the basis of art. 4 Soviet-German agreement on the protection of industrial property.

A patent was issued on July 31, 1929. The patent is valid for 15 years dated July 31, 1929.

The invention refers to the case when the polarized, installed in the neutrino position, the relay alternates with positive and negative current pulses, and the relay in response to the current pulses then switches on and off the local current source of the circuit. Such a case may occur, for example, when wiring with alternating current, when the pre-relay with the aid of direct current pulses of the alternating direction switches on the relay of the transmitter, and through the contacts of the last relay, the source of alternating current is switched on to the line. During the time that the transmitter relay’s measles is moving from one contact to another, the alternating current cannot pass, so that the pauses are prolonged and the signs are lost.

According to the invention, the increase in the exciting current of one or the other # 15609).

This direction is slowed down by the inclusion of self-induction, so that the current only after a certain time reaches the force that is necessary to disconnect the relay core from the corresponding contact. The rise time of the current in the opposite direction, in the circuit of which self-induction is negligible, lasts a much shorter time, and thus it can be achieved that the closing and opening times of the contact fully correspond to the rhythm with which the DC pulses change their direction.

The drawing shows a wiring diagram of a part of a transmission installation for wiring with alternating current.

The switch Oi, the closure of the DC pre-relay, switches through its contacts 1 and 2 alternately the positive and negative terminals of the battery b into the winding circuit of the neutral-mounted polarized relay R, the measles of which alternately touches the idle contact ri and the working contact / - g. Through the working contact is the current from the AC source S to the line /. According to the invention, the duration of the signal is increased by the fact that the ohmic, resistance Wi and self-induction Z ,, are included in the current path going through k and causing a 4/2 disconnect to occur, and the current going through 2 has the same resistance Wi. This slows down the growth of the breaking current, so that the latter reaches the necessary contact for the separation, the contact force r only by the moment of rise to its certain value.

With proper ratios between L and W, it is possible to completely: sheino prevent the shortening of the signal current time. At the same time, the conditions at the receiving end of the line also play a certain role. With

If desired, it is also possible to achieve an extension of the signal duration in comparison with the length of the pauses.

Subject Patent a.

A wiring device for direct and alternating current using polarized relays installed in a neutral position, characterized in that, with a view to increasing the duration of the signal that is sent when the terminal L closes the polarized relay R of contact r2 connected to generator S, in one of the branches going from the grounded battery b to the contacts k and k, alternately closed by the core ci (included in the R-ground winding chain) belonging to the pulse relay, the self-induction coil L and ohm are included in the branch some resistance is Wi, and the other branch includes only the ohmic resistance W, which is approximately equal in value to Wi (Fig. 2),
