Generator rotor collector ring carbon brush constant-pressure spring pressure detection device

Abstract

The invention discloses a generator rotor collector ring carbon brush constant-pressure spring pressure detection device, and mainly relates to the field of generator detection equipment. The device comprises a base and a control system, wherein a limiting ring is arranged at the center of the base, a detection body is arranged between the outer wall of the limiting ring and the inner side wall of the base, an annular sliding groove is formed in an outer wall plate of the base, a driving ring is arranged in the sliding groove, the outer side of the driving ring is in threaded connection with the wall of the sliding groove, the section of the side, close to the limiting ring, of the sliding groove is a step face, and the bottom part of the side, close to the limiting ring, of the driving ring is an inverted-cone-shaped section. The device has the beneficial effects that manual operation measurement is omitted, the spring pressure measurement efficiency is improved, the labor intensity of personnel is reduced, measurement can be carried out in a simulated use state, the measurement error is reduced, the degradation state of a carbon brush can be found as early as possible, and equipment damage accidents are avoided.

Description

technical field [0001] The invention relates to the field of generator detection equipment, in particular to a generator rotor collector ring carbon brush constant pressure spring pressure detection device. Background technique [0002] The generator rotor collector ring is a metal ring fixed on the generator rotor, which can rotate with the rotor at high speed, and the carbon brush is installed on the brush holder of the fixed part of the equipment, which is made of carbon blocks and is also called The brush is pressed with a spring on the upper end, contacts the collector ring through the spring pressure, and inputs current to the rotor winding through the wire connected to the head of the carbon brush, forming magnetic poles on the generator rotor, cutting the generator stator winding and inductively generating electricity. ; The working effect of the brush holder and collector ring system mainly depends on the pressure of the constant pressure spring on the carbon brush....

AI Technical Summary

Problems solved by technology

These methods have certain shortcomings. Manual activity experience inspection, due to the change of inspectors and uneven technical ability and experience, cannot effectively monitor the defect of weakened spring pressure, which leads to frequent occurrence of collector ring fire incidents;

[0006] However, the measurement using a spring scale is relatively accurate, but it is necessary to manually measure and record each carbon brush, which is time-consuming, laborious, and inefficient, and because the constant pressure spring is not in the working position during measurement, there is a certain error in the measurement results, which is also difficult to reflect. spring pressure result
