Description

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.
The content of the invention
In order to solve technical problem present in background technology, what the present invention provided a kind of automatic locking carbon brush arm lengths can The adjusting method of mode auto-transformer, the contact site of the carbon brush body and winding can be adjusted apart from hollow circular-tube axle center Radical length；The present invention can realize accurate adjustment, can effectively utilize the radical length of the winding；Can be by described Rotation mandrel's locking is finally fixed the position of the carbon brush body, avoids the carbon brush body with institute by locking push rod State the skew that radial direction is carried out in driving swing arm operation process.
The technical solution adopted for the present invention to solve the technical problems is：
A kind of adjusting method of the adjustable auto-transformer of automatic locking carbon brush arm lengths, uses a kind of automatic locking carbon The adjustable auto-transformer of brush arm length is adjusted；
