  • Patent number: 9222467
    Abstract: The invention relates to a transmission device for a wind turbine, having a holder, a sliding contact device having pressing means, and at least one electrode having adjustment means for transmitting lightning current. The electrode can form a spark gab having a sparking distance S together with a ring electrode, wherein the ring electrode can be arranged on the rotary device, or can be connected to a grounding device that cannot be rotated with respect to the rotary device. To improve the transmission, the holder is rotationally fixed arranged on the rotary device, or arranged in a non rotatable manner with respect to the grounding device. Furthermore, the electrode is arranged in a movable manner relative to the holder by means of a tracking device having support means. The electrode is supported by way of the supporting means relative to the rotary device or the ring electrode such that the sparking distance S can not fall below a minimum dimension.

  • Patent number: 9203232
    Abstract: The present invention relates generally to a leakage detection protective circuit. This leakage detection protective circuit includes a rectification circuit, a current-limiting resistance, a controlled silicon rectifier (SCR), a power supply main circuit switch linked with a reset button and a tripping coil with a built-in iron core. The rectification circuit, tripping coil, and SCR are connected in series with each other, forming a circuit. The control pole of the SCR is connected, through the current-limiting resistance and the diode, to the shielding layer of the power output wires. When a leakage failure occurs, the shielding layer connected to the control pole of the controlled silicon rectifier becomes electrified, triggering the controlled silicon rectifier. A magnetic field is then generated within the tripping coil and its built-in iron core moves, causing the reset button to trip. This invention is characterized by a compact circuit and robust operation.

  • Patent number: 9184580
    Abstract: An arrester includes a switch and a lightning detection breaker connected to the switch. The lightning detection breaker includes a metal conducting terminal electrically connected to an earth return, a DC power supply terminal, a ground terminal and an output terminal. When the power supply is under a lightning strike, a potential difference of both the DC power supply terminal and the ground terminal of the lightning detection breaker will go up to several thousands of volts. However, a voltage of the metal conducting terminal will not go up because the metal conducting terminal is electrically connected to the earth return. The switch will automatically become open circuit by the lightning detection breaker, and therefore an electronic device connected to the arrester is protected from damage done by the lightning.

  • Patent number: 9160164
    Abstract: A method and apparatus for fault detection of series diodes in rectifiers is disclosed, wherein the voltages across one or both of the individual diodes, and/or the voltage across the pair of diodes are measured to determine a ratio between two of those voltages. The ratio is then analyzed to determine if a fault (e.g., a short circuit or an open circuit) is present. In some embodiments, circuitry can be included to compensate for the normal variations in diode characteristics (e.g., reverse leakage current, reverse recovery charge) between the pair of series diodes to minimize the potential for erroneous fault detection.
