Abstract: A pulsation damper for damping pressure medium vibrations in a hydraulic system, has a membrane within a bore of a housing, which membrane is exposed to the pressure medium on its one side and faces a gas-filled cavity inside the housing on its other side, the bore of which is closed by means of a plug. The membrane, in conjunction with the plug and a hollow-cylindrical support body, forms an independently handleable, functionally pre-testable assembly, for which purpose the membrane is substantially cup-shaped, and the support body extends into it.

Abstract: The disclosure provides a cable protection device and a wind generator set. The cable protection device comprises: a fixing ring, which has a through hole extending along a first direction, wherein the fixing ring includes an inner side surface and an outer side surface that are opposite along a radial direction of the fixing ring, the outer side surface comprises two or more attaching surfaces, and a vertical axis is defined in the attaching surface; and a clamping member, which is disposed on the attaching surface, wherein the clamping member is deflectable at least about the vertical axis, the clamping member has at least one penetration hole penetrating along the first direction, and a cable is clamped within the penetration hole and is deflected about the vertical axis relative to the fixing ring within a preset range.

Abstract: A lightning protection device for a wind turbine generator system includes at least a blade arrester, a down lead of a blade connected to the blade arrester, a lightning-proof element of a pitch bearing, a lightning-proof element of a rotor bearing. The lightning-proof element of the pitch bearing is arranged at the blade root, with one end connected to the down lead of blade and the other end connected to the lightning-proof element of the rotor bearing. The lightning protection device forms a lightning current conducting path passing through a cavity of the pitch bearing, a hollow of a rotor shaft and a cavity of the rotor bearing. A wind turbine generator system having the above mentioned lightning protection device is provided.

Abstract: Disclosed is a tower for a wind power station comprising a machine pod disposed on the tower and a rotor mounted on the machine pod so as to be rotatable about an essentially horizontal axis. Said rotor is provided with at least one blade. The tower is composed of a tubular upper section that is connected to a lower section which is embodied as a lattice tower in a transition zone. The lattice tower encompasses at least three corner posts. The upper tower section forms at least one sixth of the entire tower. The cross section of the lower tower section below the transition zone is greater than the cross section of the upper tower section while the transition zone is configured such that the cross section of the lower tower section is adjusted to the cross section of the upper tower section so as to optimize power flux.

Abstract: A device for the targeted adjustment of the angle of incidence of a rotor blade (13) which is rotatably mounted, at the foot (14) thereof, on a hub (12) of a rotor (11) of a wind power installation (10). The device includes a gearing, a driving toothed wheel (21, 41) that meshes with the gearing (20, 40), and a lubricating device. The lubricating device, due to a temporary displacement of the driving toothed wheel (21, 41) from an operating position into a lubricating position, can be engaged with a defined point of the gearing (20) or the driving toothed wheel (41), respectively previously engaged with the driving toothed wheel (1) or the gearing (20, 40), so as to transfer lubricant.
