Problems solved by technology

[0007] During the operation of the unit, the collector ring rubs against the carbon brush, and a large amount of carbon powder produced will contaminate the relevant components of the collector ring, resulting in serious safety hazards such as reduced insulation performance of the insulating parts of the exciter equipment, zero point grounding, and high temperature of the carbon brush.

Abstract

When an old-fashioned direct-current exciter runs, carbon powder drifts and accumulates seriously, so that the temperature of a collecting ring is high, the insulating property of electrical equipment is reduced, and the safety of a unit is reduced. In order to solve the problems, a carbon powder collecting device is additionally arranged, carbon powder is sucked out and treated through the carbon powder collecting device, the temperature of the direct-current exciter and the carbon brush during operation is reduced, and the utilization rate and reliability of the carbon brush and the direct-current exciter are improved.

Description

Technical field [0001] The present invention belongs to the field of power, and more particularly to a generator DC excitation machine toner collecting device. Background technique [0002] Liu Jiaxia Hydropower Station was officially started on September 27, 1958, and the first unit was gridnet power generation on March 29, 1969. On December 5, 1974, all installed and put into production. In the Northwest Power Grid, the power generation, peak, frequency modulation and pressure regulation tasks are mainly assigned, and it is the backbone power station of the Northwest Power Grid and is in a very important position in the Northwest power system. So far, Liujiaxia Power Station has stabilized more than 50 years. In recent years, the problem of carbon powder accumulation in the power station has gradually threatened the stable operation of the power station. [0003] In view of the important position of Liujiaxia Power Plant in the Northwest Power Grid, the work engrave of the stab...
