| 20120039011 | TRANSMISSION DEVICE FOR A WIND TURBINE - 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. | 02-16-2012 |
| 20120162845 | System for Protecting Wind Turbines Against Atmospheric Discharges - By means of a series of parameters taken by the plurality of sensors, the system of the invention makes it possible, via a central control unit provided with complementary programming firmware, to activate an electric-field compensating device ( | 06-28-2012 |
| 20120194960 | Wind Turbine Blade with an Integrated Lightning Conductor - A method is provided for manufacturing a wind turbine rotor blade in which the blade is formed as a laminated structure by laying a composite material of fibre reinforcement material and/or core material in a mould defining the shape of the blade; evacuating the mould after laying the composite material; introducing a liquid polymer into the evacuated mould and wetting the composite material; curing the liquid polymer after the composite material has been wetted; and removing the mould after curing the liquid. At least one lightning conductor is integrated into the composite material before wetting it with the liquid polymer. Moreover, a wind turbine rotor blade made from a single laminated structure is provided with at least one lightning conductor is integrated into the laminated structure. | 08-02-2012 |
| 20120287549 | WIND POWER GENERATION SYSTEM - In one embodiment, a wind-power generating system | 11-15-2012 |
| 20130222965 | Arrester - 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. | 08-29-2013 |
| 20140313632 | OVERVOLTAGE PROTECTION DEVICE HAVING AT LEAST ONE SURGE ARRESTER - The invention relates to an overvoltage protection device, comprising at least one surge arrester and one switchgear assembly, which is connected in series to the surge arrester and which can be triggered thermally, wherein the aforementioned components form a structural unit, and the thermal tripping means is arranged in the area of the expected heating up of the surge arrester when overloaded. According to the invention, the thermal tripping unit is configured as a stop element through which operating current or surge current does not flow. In the event of thermal overload, the stop element opens a releasing device of the switchgear assembly, wherein said switchgear assembly has an increased self-extinguishing capacity. | 10-23-2014 |
| 20150303684 | Lightning Protection Component - A lightning protection component, with at least one main input capable of transmitting a lightning signal, at least one main output designed to be connected to a piece of equipment (T) to be protected from the lightning signal, a branched output designed to be connected to a dissipation circuit (M), a direct line connecting the main input to the main output, a bypass circuit that is mounted between the direct line and the branched output, and that is provided with at least one bypass switch having an open state in which the branched output is isolated from the direct line and a closed state in which the lightning signal is conducted from the direct line to the branched output. | 10-22-2015 |
