    摘要: A hydropower plant for regulating the frequency of an electric grid has an upper water reservoir; a lower water reservoir; a waterway that connects the upper water reservoir with the lower water reservoir. A turbine that is arranged in the waterway includes a runner, a guide vane apparatus and a device for blowing out the runner space. An electric synchronous machine is mechanically connected to the turbine and a frequency converter is electrically connected to the synchronous machine. A mains transformer is electrically connected to the frequency converter and the mains grid. A resistor is connected in a DC intermediate circuit of the frequency converter in such a way that it may connect the line sections of the DC intermediate circuit to one another. The assembly also includes a device for cooling the resistor.

    摘要: A heat sink assembly for an alternator. The heat sink assembly includes a clip for clipping the heat sink assembly onto a diode rectifier heat sink of the alternator. Thermally conductive material is on an inner surface of the clip. A heat sink is on an outer surface of the clip opposite to the thermally conductive material, and includes fins. Thermal energy from a hotspot of the alternator to which the heat sink assembly is clipped is conducted to the heat sink by way of the thermally conductive material and is radiated from the fins to cool the hotspot.

    摘要: A wearable electronic device including an electromagnetic induction generator, a rectifier circuit, and an energy storage is provided. The electromagnetic induction generator includes a magnet and a flexible thin film. The flexible thin film is provided with an induction coil. When a relative position between the magnet and the induction coil changes, a magnetic flux passing through the induction coil changes so that an induced current is generated. The rectifier circuit is electrically connected between the induction coil and the energy storage and is configured to receive the induced current to charge the energy storage.
