A kind of adjusting method of the adjustable auto-transformer of automatic locking carbon brush arm lengths
Technical field
The present invention relates to electric apparatus technical field, and in particular to a kind of adjustable self coupling of automatic locking carbon brush arm lengths
The adjusting method of transformer.
Background technology
Pressure regulator is similar with the function of transformer, is all the conversion 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, power supply end does not often reach predetermined voltage, therefore carries out voltage stabilizing using pressure regulator.During electrical test, distribution substation
The interior equipment with different voltage class, 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, it is applied in real process
Voltage output value simply in some specific a small range.And because the length of carbon brush is certain, carbon brush is in rotation process
The track of middle formation is the circular trace that radius is fixed so that winding is constantly worn in the circular trace, or even burns out and set
It is standby.And winding then keeps good at the position of other radius Circular tests, it is impossible to effectively utilize.
Therefore need to design a kind of method that can adjust self-coupled transformer carbon brush length, effectively avoid lacking for prior art
Fall into.
