The thermal power station is a power station in which heat energy is converted to electric power. Water is heated, turns into steam and spins a steam turbine which drives an electrical generator. Slip rings, able to be used at any electromechanical rotating system, are also employed in the system of thermal power station.
JINPAT slip ring for thermal power stations is a kind of large-current electrical part with many circuits. The thermal power station slip ring can transmit power signal, servo motor signal, and encoder signal. The whole process of signal transmission is reliable with no interference due to isolation handling. As for the two parts of large power and signal, an individual slip ring with a copper graphite contact and through bore part with filament contact are designed respectively.
