Systems and methods for overvoltage protection are disclosed. According to one illustrative implementation, an overvoltage protection device is provided having one or more overvoltage protection elements and a measuring device for monitoring the overvoltage protection elements. Further, the measuring device may include an evaluation device, which is designed to count pulse-like overvoltage events which are arrested by the overvoltage protection element, wherein the evaluation device is connected to the overvoltage protection element via a light-measuring device and/or a device for identifying a current flow. In further implementations, overvoltage protection devices may comprise an evaluation device which, on the basis of the counted pulses and/or an identified current flow, may determine whether the overvoltage protection element is still operational, is previously damaged, or is unusable, and/or an alarm device, which indicates whether the overvoltage protection element is still operational, is previously damaged, or is unusable.

摘要:
An overvoltage protection element with a housing, an overvoltage-limiting component arranged in the housing, and with two connection elements for electrically connecting the overvoltage protection element to the current or signal path to be protected, wherein, normally, the connection elements are each in electrically conductive contact with a pole of the overvoltage-limiting component. Reliable and effective electrical connection in the normal state and reliable isolation of a defective overvoltage-limiting component are ensured by the fact that a thermally expandable material is arranged within the housing in a way that, in the event of thermal overloading of the overvoltage-limiting component, the position of the overvoltage-limiting component is changed by expansion of the thermally expandable material relative to the position of the connection elements in a way that causes at least one pole of the overvoltage-limiting component to be out of electrically conductive contact with the corresponding connection element.

A planetary gear mechanism for a wind power plant includes a sun gear, an internal gear and a planetary carrier with planetary gears supported by radial and axial slide bearings. The radial slide bearings include a sleeve made of a slide bearing material and attached as an inner ring to a planetary gear shaft or mounted as an outer ring in a bore in a planetary gear. An outer bearing ring cooperating with the inner ring is formed by the bore in the planetary gear, or an inner bearing ring cooperating with the outer ring is formed by the planetary gear shaft. A slide bearing material of a first bearing element of the axial slide bearings is applied between a planetary carrier cheek and an end side of a planetary gear. The end side of the planetary gear or the planetary carrier cheek forms a corresponding cooperating second bearing element.

A method for measuring the temperature of substrates to be coated is disclosed. The substrates have an opening or a cavity, and the substrates are successively moved past a source of coating material. At least one substrate's temperature is measured during coating by at least one temperature sensor and the measured temperature value is transmitted to a measuring device. The temperature sensor is disposed inside the substrate's opening or cavity so as to prevent coating of the temperature sensor.
