Description
Technical field
The present invention relates to technical field of electricity, and in particular to a kind of flexible adjustable auto-transformer of damping of carbon brush body
Adjusting method.
Background technology
Pressure regulator is similar with the function of transformer, is all the transformation for carrying out voltage.The pressure regulator unlike transformer
The voltage of output end output can adjust.In the power supply-distribution system of rural area, due to long distance powedr transmission, voltage loss is tight
Weight, predetermined voltage is often not achieved in power supply end, therefore carries out voltage stabilizing using pressure regulator.During electrical test, distribution substation
The interior equipment with different voltages grade, it is therefore desirable to which the power supply power supply to the device of different voltages, pressure regulator can play weight
The effect wanted.
In above-mentioned application process, although the output of pressure regulator is from 0 to maximum value, it is applied in real process
Voltage output value only in some specific a small range.And since the length of carbon brush is certain, carbon brush is in rotation process
The track of middle formation is the fixed circular trace of radius so that winding is constantly worn in the circular trace, or even burns out and set
It is standby.And winding is then kept well at the position of other radius Circular tests, cannot be efficiently used.
Therefore it needs to design a kind of method that can adjust self-coupled transformer carbon brush length, effectively avoids lacking for the prior art
It falls into.
