An adjustment method of an adjustable autotransformer that automatically locks the length of the carbon brush arm

Abstract

The invention relates to an adjustment method of an adjustable auto-transformer capable of automatically locking length of a carbon brush arm, and the adjustable auto-transformer capable of automatically locking length of the carbon brush arm is adopted for adjustment; the adjustable auto-transformer capable of automatically locking length of the carbon brush arm comprises a shell, annular iron cores, windings and a carbon brush arm; the adjustment method comprises the steps of 1, rotating a driving handle; 2, maintaining the position of a carbon brush body; and 3, performing reciprocating extension and retraction of the carbon brush body. By adoption of the adjustment method of the adjustable auto-transformer capable of automatically locking length of the carbon brush arm, the radial length from the contact part, between the carbon brush body and the winding, to a hollow circular tube axis can be adjusted; accurate adjustment can be realized, and the radial length of the winding can be utilized effectively; and a rotational core shaft can be locked by a locking top rod, and the position of the carbon brush body can be fixed finally, so that radial offset of the carbon brush body in transfer process of a driving swing arm can be avoided.

Description

technical field [0001] The invention relates to the technical field of electrical equipment, in particular to an adjustment method of an adjustable autotransformer that automatically locks the length of a carbon brush arm. 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 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.
