SU114519A1 - Device for generating and controlling the phase of control pulses of ion converters - Google Patents

Description

For generators and phase control of impulse-controlling ion transducers, devices are used that contain a mechanical commutator, driven by a synchronous electric motor with subtle poles.

Known similar devices with the South circuit and do not ensure reliable operation of the converter, which limits their use.

In order to eliminate these drawbacks, it is proposed to perform a switch in the form of a disk with steel nuts that nzl-generate magnetic resistance of the gaps of the cores of the peak transformers, the primary windings of which are fed by direct current. For control, 1pp phase impedance induced in the secondary windings of peak transformers, the utor is provided with two windings shifted relative to each other by 90 electrical degrees, the ratio of the currents in which determines the displacement of the resulting motor field.

The drawing shows the electrical circuit; Deliverable device.

Device; (1 contains synchronous: motor / with pneumatic 5H pole poles, equipped with two excitation windings 2 and 3, streamlined by direct current and creating positive magnetic fields, shifted relative to each other by 90 electrical degrees. HI types 5. These shifts pass alternately through the air gaps of the cores of peak transformers 6, the primary windings 7 of which are fed through large inductances 8 by direct current. As a result, at the moment the pins 5 pass through the gaps of peak-m sformatorov in Hx secondary windings 9 induktiruyuts emf in the form of short pulses with a steep rising edge.

These pulses are applied to transformers 10 and are used as control signals in the thyratron grid circuits or in the ignitron igniter circuits.

An appropriate choice of the rotational speed of the synchronous motor} and the openings.m of the pins 5 provides for the necessary ignitron ignition program.

Ignitron ignition phase control is accomplished by changing the rotor position of the two rotors relative to the rotating field of the stator, which is achieved by a corresponding change in the currents in the windings of excitation 2 and 3.

One of these field windings is connected to a current source 11 with a stable voltage, and the other to a rectifier 12 with a voltage proportional to the voltage of the network supplying the ion converter. With such switching on of windings 2 and 3, the effect of the oscillations of a1H1 in the supply network on the output voltage of the converter is achieved.
