  • Patent number: 10559933
    Abstract: A manual disconnect for an electric circuit includes a base with primary terminals and an interlock connector. A plug assembly has fuse terminals and an interlock resistor assembly. The plug assembly is adapted to be moved relative to the base between a disconnected position, a primary circuit engaged position, and an interlock position. The plug assembly is moved linearly and rotationally relative to the base when moving between these positions. The manual disconnect also includes a connector position assurance assembly. The connector position assurance assembly includes a connector position assurance button that is movable relative to the plug assembly. The connector position assurance button can be moved between a pre-lock position and an assurance position. When located in the assurance position, the connector position assurance assembly prevents the plug assembly from rotating relative to the base.

The lightning protection structure of the blade for wind power generation includes a conductive lightning receptor 1 attached to a part of the blade for wind power generation, and a ceramic member 10 interposed between at least surface-layer portions of the lightning receptor 1 and the blade 5. Therefore, an electric field is likely to concentrate at an interface between the ceramic member 10 having excellent heat resistance and the lightning receptor 1, so that it is possible to effectively prevent the blade 5 from being damaged due to a concentration of the electric field at the interface of the blade 5 attached with the lightning receptor 1 when arresting the lightning.

  • Patent number: 9007739
    Abstract: A protective system is provided including a material comprising a first and second surface opposite one another and a thickness, and where the first surface has a low-electrical resistance and the second surface has a high-electrical resistance that is higher than the electrical resistance of the low-electrical resistance surface, and the material conducts charge from the first surface to the second surface through the thickness. This can be provided in a bilayer structure where a first protective layer having a low-resistivity is disposed upon a second protective layer having a high-resistivity. This protective system is particularly useful for dissipating electrical charge, for example as a lightning strike protection system for composite aircraft.

  • Patent number: 9001485
    Abstract: An overvoltage protector includes a first discharging electrode, a second discharging electrode, and an overvoltage protection part provided between the first and second discharging electrodes. The overvoltage protecting part has an insulating property under a normal operation condition, and has a conductive property if an overvoltage is applied between the first and second discharging electrodes. The overvoltage protecting part is made of a mixture of resin having an insulation property, an inorganic compound having an insulating property, and metallic boride compound powder. The metallic boride compound powder has a high melting point therefore it is hardly melted. Under high temperatures causing the powder to melt, the powder is oxidized and loses conductivity, thus providing a high reliability.

  • Publication number: 20150022932
    Abstract: A fault-tolerant self-indicating surge protector system and methods are presented. An unwanted surge of electrical energy induced by a lightning strike is directed away from a sensitive electrical or electronic component, and the unwanted surge of electrical energy is directed through series connected pairs of varistors. A voltage signal is extracted from a center tap point between the series connected pairs of the varistors, and the voltage signal is monitored for a health of the varistors. A high impedance in a varistor among the varistors is provided for a low voltage across the varistor, and a low impedance in the varistor is provided and the unwanted surge of electrical energy is diverted through the varistor in response to a high voltage across the varistor.
