Adjusting method of autotransformer with adjustable telescopic damping of carbon brush body

Abstract

The invention relates to an autotransformer with adjustable telescopic damping of a carbon brush body. The autotransformer comprises a shell, annular iron cores, windings and a carbon brush arm. The invention further relates to an adjusting method of the autotransformer with the adjustable telescopic damping of the carbon brush body. The method comprises the following steps of step 1, rotating a rifled tube; step 2, carrying out reciprocated telescoping of the carbon brush body; and step 3, adjusting the telescopic damping of the carbon brush body. According to the adjusting method, the radiallength from a contact part of the carbon brush body and the windings to the axis of a hollow round tube can be adjusted; accurate adjustment can be realized, and the radial length of the windings canbe effectively used; the telescopic damping of the carbon brush body can be adjusted, and the uncontrollable telescoping caused by unsmooth winding surface shapes when a telescopic flat plate and thecarbon brush body slide on the windings is avoided; the damping adjustment of the telescopic flat plate and the carbon brush body in two different contact forms can be realized.

Description

technical field [0001] The invention relates to the field of electrical technology, in particular to a method for adjusting an autotransformer with adjustable telescopic damping of a carbon brush body. Background technique [0002] The functions of the voltage regulator and the transformer are similar, and they both perform voltage transformation. Unlike a transformer, the output voltage of a voltage regulator can be adjusted. In the rural power supply and distribution system, due to the long-distance power transmission, the voltage loss is serious, and the power supply terminal often cannot reach the predetermined voltage, so a voltage regulator is used for voltage stabilization. In the electrical test process, there are devices with different voltage levels in the power distribution station, so power supplies with different voltages are required to supply power to the devices, and voltage regulators can play an important role. [0003] In the above application process, a...

[0003] In the above application process, although the output of the voltage regulator is from 0 to the maximum value, the voltage output value applied in the actual process is only in a specific small range

And because the length of the carbon brush is fixed, the trajectory formed by the carbon brush during rotation is a circular trajectory with a fixed radius, so that the winding is constantly worn on the circular trajectory, and even burns out the equipment.

However, the windings are well maintained at other radius circle tracks and cannot be effectively utilized.
