SU112124A1 - Device for automatic introduction into the phase of the receiving distributor of the synchronous telegraph apparatus - Google Patents

Description

Devices for the introduction into phase of receiving receivers of synchronous telegraph devices, in which the introduction into phase is carried out manually or mechanically, are known.

Their disadvantage consists in the necessity of interrupting the work of the transmitting stations from the moment of loss, in phase until the moment of entering the phase.

A feature of the described device,; in which the indicated disadvantage is eliminated, is that by appropriately switching on the diodes and the trigger circuit, an error is detected in the reception of the correction combination accumulated by the distributor on the capacitors, in addition, for communication between the master oscillator 01M and the distributor actuators as “An electronic clutch is used for the following: an intermediate generator, synchronized by the master oscillator and output, from synchronization at the time of the part of each cycle of the receiving distributor The purpose of the phase shift of the latter.

The drawing shows the scheme of the proposed device: TWA.

A device consisting of a block for isolating an error during the arrival of correction pulses, a block holding the beginning of the search for the phase, and an actuating block performing the search contain diodes .-- Dz-D., L: -L- trigger lamps. 73-intermediate generator and L, relay Pi-P-Rz-P4,

R a b about t device. In the case of the correct phase, the correction combination will be accumulated by the receiving distributor on the capacitors Ci + C4. Following the accumulation of the corrective combination, the relay Pi, which is included in the contact of the distribution ring, will operate: ITEL, and the charges of the capacitors Ci + C-i will be through diodes on the grids of the L1 + L trigger lamps ...

1: slightly, l is correctly typed, the voltage of the collectors will not fall on the set of lamn, so 1sak will pass in the direction of the diode; under these conditions, the // 1 lamp will be closed, and // - open. Such a newfound trigger)), -. It will be confirmed for every turnover. Separate the pulse of the contact of its sec. ring.

In case of accumulation of an emergency sign on one of the Cr: C-i capacitors, at the instant PI T1 triggers the trigger will move to another position and the relay P will keep the Arrows pressed before they receive the 1NO1 pulse from the service colp. The capacitors C.-, and Cf, protect the LgL trigger from being triggered by impulse noise.

As a result of the operation of the relay Pi-1M-kits, the relay circuit P3 and a phase search circuit is prepared which is still open by the contacts of the relay f-i; Рз will work and block for one turn of the distributor; the capacitor G, which maintains a negative mixture, 1, pa of Grid L ;, will switch the discharge through the resistance. They sang the receiving distributor ne in phase, then Pz will be held short, until C loses a negative charge and the L-spar L-1 opens, Pi works and the search circuit closes. Iloe.ie this operation of the relay P: will affect the electronic clutch, in which 1 is used by the generator Lz, causing a jump; 1 calling it or overtaking. At each sraPen ShA Pa, parallel to one of the resistors: 1fi 1 of the phase-shifting loop of the Lo generator, the resistance PI will be connected, i.e. for some time the oscillator frequency L, - ,; resistance / pick up so that for. lipcMsi

Thus, when working i: in pe / i P; for the time of each .1; 1 scan of the P. contacts. the distributor brushes will be heated on the contact until the norm until the capacitance Cr-.Ci has iran of the grain | Then Pi NS is triggered and through the resistance P-to Snappet ondeducer accumulates a mine charge. Some time, depending on the value of the resistance P 3, the Pt relay will hold the measles, keeping the circuit ready for phase; then PI from measles will stop and the scheme will automatically come to its end.
