Abstract

The invention relates to a carbon brush body telescopic damping adjustable type autotransformer and an adjusting method thereof. The autotransformer comprises an outer shell, annular iron cores, windings and a carbon brush arm. The adjusting method includes: step 1, rifled tube rotation; step 2, reciprocated telescoping of a carbon brush body; step 3, telescopic damping adjustment of the carbon brush body. The adjusting method has advantages that the radial length 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 radial length of the windings can be effectively used; telescopic damping of the carbon brush body can be adjusted, and uncontrollable telescoping caused by unsmooth winding surfaces when a telescopic flat plate and the carbon brush body slide on the windings is avoided; damping adjustment of the telescopic flat plate and the carbon brush body in two different contact formscan be realized.

Description

Technical field [0001] The invention relates to the field of electrical technology, in particular to an autotransformer with an adjustable expansion damping of a carbon brush body and an adjustment method thereof. Background technique [0002] The functions of a voltage regulator and a transformer are similar in that they both perform voltage conversion. The difference with the transformer is that the output voltage of the output terminal of the 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 end often cannot reach the predetermined voltage, so a voltage regulator is used to stabilize the voltage. In the electrical test process, the power distribution station has equipment of different voltage levels, so different voltage power supplies are required to supply power to the equipment, and the voltage regulator can play an important role. [0003] In t...
