Support adjusting rod of carbon brush holder

Abstract

Disclosed in the invention is a support adjusting rod of a carbon brush holder. The support adjusting rod comprises a support rod screwed into a foundation; and the top of the support rod is connected with a cylinder manifold in an insulation mode. One side of the cylinder manifold is connected with a power supply and the other side is connected with a carbon brush holder. Pressure-bearing insulation pads are respectively arranged at the upper side and the lower side of the connection part of the cylinder manifold and the support rod; a gland nut is arranged above the pressure-bearing insulation pad at the upper side and the pressure-bearing insulation pad arranged at the upper side is compressed at the cylinder manifold tightly by the gland nut; and a locking nut for preventing the gland nut from loosening is arranged on the gland nut. A locking nut contacting a footing tightly is arranged at the lower portion of the support rod, a bearing nut is arranged above the locking nut; and a high-strength insulation sheath sleeving the support rod is arranged between the bearing nut and the pressure-bearing insulation pad arranged at the lower side and an insulation filling material is arranged in the high-strength insulation sheath. According to the invention, the support adjusting rod has a simple structure and materials are available; and the rod can be manufactured and installed conveniently. Moreover, the support adjusting rod has an insulation function; and the support function of the brush holder can be enhanced further, so that the usage safety of the rod can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of electrical accessories, in particular to an umbrella-shaped generator rotor carbon brush holder support adjustment rod. Background technique [0002] In a hydroelectric power plant, the connection between the excitation coil of the generator rotor and the excitation rectification system usually requires the use of a carbon brush holder. The traditional carbon brush holder is supported by several (generally six to eight) support rods screwed into the footing. The carbon brushes are mounted on In the carbon brush holder, the carbon brush holder is fixed on the manifold, the carbon brush leads are connected to the manifold, the manifold is fixed on the top of the support rod and insulated from the support rod, the manifold is connected to the excitation power supply, and the lower part of the support rod is provided with a Lock nuts for footings. When the support bar of this kind of support frame fixes the ...

AI Technical Summary

Problems solved by technology

When the support bar of this kind of support frame fixes the manifold, the insulating layer directly bears the pressure of fixing the manifold, which is easy to loosen and sink; if the manifold is loose and sinks when the equipment is running, it may cause the generator to lose Excitation, causing accident shutdown, hidden danger of grounding or short circuit of excitation system, causing major accidents and equipment damage
