Description

Cxew / jTHHecKoe image of the described device is shown in the drawing.

The device for tuning coal rotors of voltage consists of tank 1, atalol resistor 2, rheostat 3, switch 4, tunable coal rotor-tor, containing coal table 5, obmitku 6 coal regulator, reior iop 7, screw 8 settings , Measles 9, hearts iinh 10.

The device works as follows

In order to configure the device of the switch 4, turn on the resistor 7 of the regulator 5p1 i pajna-CTpooHHoiD in the actual control system, use the rheostat slider 3 to set the required charging current for the coal column 5, and by changing the voltage with the power source the required voltage between points a and b. Then switch 4 in the circuit of the winding 6 of the carbon regulator includes a reference resistor 2, by changing the resistance of which the necessary parameters of the device are restored.

After that, the regulator is replaced with a tuned one and is tuned with a reference resistor 2.

When the adjustment screw 8 is moved, the previously loosened coal pillar 5 begins to compress, thus eliminating the gaps between its washers (not indicated in the drawing), the resistance of the coal pillar 5 and the voltage on it decrease.

Since the supply voltage of the device during the adjustment process remains constant, the voltage on the winding 6 of the carbon regulator between the points of the string begins to rise.

The force of the electromagnet (not indicated in the drawing) due to the relatively large dazor between the core 9 and the core 1O is not enough to move the core 9. With further movement in setting 8 of the setting, the voltage rise between points b and d stops, and then the voltage starts to decrease , since the force of the electromagnet begins to prevail with the mechanical force of the spring of the core 9. At this, the force of pressing the coal column 5 decreases, its resistance and the voltage on it increase. In a certain zone, the force of the electromagnet significantly exceeds the force of the spring (not shown) of the core 9, therefore

Measles 9 are sharply attracted to the core. Yu. The resistance yjD / ibnor-o of column 5 and the voltage across it also sharply breaks; they melt and the voltage on the winding of the carbon regulator between points b and g decreases with delay, caused by the discharge time of the capacitance 1, then the reverse redistribution of stresses begins. This phenomenon characterizes the unstable operation (clapping mode). The operating point is set outside the clap zone. After setting the operating point, switch 4 turns on the resistor 7 of the tuned controller, by varying the resistance of which the parameters obtained by adjusting the regulator with the reference resistor 2 are set.

This device allows with sufficient accuracy to adjust the coal voltage regulators with a relatively low power consumption, on the order of 50 o watts. The power consumption in a real system is at least 16 kW. The insignificant power consumption and dimensions, the absence of noise allows adjustment of the regulators directly at the assembly site of the toro regulator.
