Abstract
The utility model relates to an electric generator, in particular to a grounding carbon brush device of a water-wheel electric generator. A carbon brush component is installed on an insulating board by a fastening piece; the insulating board is located and arranged on a square column; a carbon brush of the carbon brush component clings to a main shaft of the electric generator in a sliding way under the push press of a spring; the carbon brush of the carbon brush component is grounded by a lead; and the square column is installed on a stander besides the main shaft of the electric generator or on a part fixedly connected with the stander. The grounding carbon brush device effectively eliminates shaft current generated in the operation of the electric generator, thus stabilizing the performance of the electric generator, improving the reliability of the operation of the electric generator and prolonging the service life of the electric generator.
Description
Technical field
The utility model relates to a kind of ground connection carbon brush configuration, particularly a kind of generator ground connection carbon brush configuration that comprises hydraulic generator.
Background technology
Motor is in manufacture process, and the stator piece assembly unit has indirect slit slightly, and rotor has many workmanships such as off-centre all can produce shaft current slightly; The oil reservoir that exists in the bearing can not form enough insulation to shaft current again, when shaft current is passed bearing, bearing shell, the working surface of bearing, bearing shell is caused the electricity feedback, influence motor performance and causes electrical fault.
Summary of the invention
The purpose of this utility model provides a kind of generator, and particularly a kind of hydraulic generator ground connection carbon brush configuration is in order to the shaft current of the motor performance of eliminating the effects of the act.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of generator ground connection carbon brush configuration, comprise carbon brush component, and described carbon brush component is installed on the insulation board by securing member, and the insulation board location and installation is on square column; The carbon brush of described carbon brush component slides and is close to generator shaft under the pushing of spring, and the carbon brush of carbon brush component is by lead ground connection.Described square column location and installation the frame that is positioned at the generator shaft side or with parts that frame is fixedlyed connected on.
The beneficial effects of the utility model are: the ground connection carbon brush configuration can be eliminated the shaft current that produces in the generator operation effectively, and the stable generator performance improves the generator operation reliability, prolongs generator useful life.
