Description

In existing compensation schemes, based on the "induction principle (Trub-Tauber system), it is often necessary to use a receiver as a recording device with rapid changes in the position of the sensor frame, for which it is necessary to increase the installation moment of the receiving device.

The proposed device makes it possible to obtain a reduction in the installation time of the receiving device in a rather simple way.

The device is shown in FIG. 1 of the drawing, where a circuit diagram with a battery-powered triode amplifier is shown, and in FIG. 2, where a circuit is shown using a dual network triode amplifier with mains power; FIG. Figures 3 and 4 show the variation curves of the circuit currents.

The proposed device (Fig. 1) consists of a sensor I, a receiver I II, frames 1 and 2, a capacitor 3, a transformer 4, a separation transformer 5, a power supply battery B and a lamp 6.

The operation of the proposed device occurs as follows.

When agreed; In the position of frames 1 and 2 of the devices, the voltage between points (a) and (b) of transformer 4 is equal to у and constant current flows in the anode circuit of lamp 6, which does not affect the circuit of the induction devices.

When the system mismatches between points (a) and (b) of the winding of the transformer 4, Vits voltage EL, which, due to the presence in the circuit and capacitance 3, will be shifted relative to the resulting emf. DE at / 90 °. In order to obtain the maximum value of Eb with the same system mismatch, the circuit consisting of two frames (sensor and receiver), transformer 4 and isolation transformer 5 is tuned with capacitance 3 to resonance. In this case, the current (variable component) flowing through the anode circuit 6 under the action of grid voltage EL will have a maximum value and will coincide in phase with the excitation flow of the receiving device.

The variable component of the anode current of the lamp 6 appears when there is an EL lamp on the grid. induces in SU secondary, winding separator of the transformer 5 alternating current, which depends on the direction of the voltage, or

In the arrangement diagram shown in FIG. 2 of the drawing, all threading is reduced from the AC mains through transformer 7. The operation of the circuit is somewhat different from the previous one.

When matching the nal system, the same i-ie between points (a) and (1)) of the transformer Mat 4 is zero and the anode circuit of the binary triode 6 passes through the primary winding of the isolation transformer 5 and the oscillating current 1a.

In the secondary winding of the transformer is induced by a variable emf. double frequency, the current from which, irokhod frame 2, does not create a moment.

In case the system mismatches, between points (a) and (b) of transformer 4 is the Vts voltage, which, due to the presence of capacitance 3 in the circuit, will be shifted relative to the resulting electromotive force equal to the difference between the electromotive forces of the receiver and sensor frames , i.e., -E, at 90. A circuit containing frames 1, 2 n tr-enformator 4, is adjusted with or at a capacity of 3 to resonance (this depends on the shift between Е „and Еud), which makes it possible to get the maximum value - EL - EL voltage applied to the grid and cathode l 6 mpy, affects the currents of each anode.

The offset to the grid is chosen in such a way that if there is a positive potential on the anode, and on the grid there is an additional negative, you., Called the system mismatch,

The anode current of this anode decreases to zero. Consider the case of a mismatch when E is E, i.e., LU is positive. The current of the first anode increases, and the second decreases, and the current shown in phi-g will flow through the primary winding of the separation transformer. 3

As a result, a current I will flow through the secondary winding of this transformer, which, interacting with the excitation flow of the receiver, will rotate frame 2.

For the second case of mismatch, when E, the current I will be shifted relative to the current I of the first case (when) by 180, which will cause the opposite sign (Fig. 4 shows the currents of each anode for the case and the resulting current lab

The presence of a capacitor 3 in the circuit is not necessary, since during a shift between E "and EU, the current I will contain a component that coincides with the excitation flow of the receiving device.
