摘要:
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, with at least one overvoltage limiting component which is located in the housing, with terminal elements for electrical connection of the overvoltage protection element to the current or signal path which is to be protected, and with a state display which has a display element for display of the state of the overvoltage protection element. A conclusion about the state of the overvoltage protection element is easily possible as a result of a thermally activatable, endothermic material being both in thermal contact with the overvoltage limiting component and also in mechanical contact with the display element of the state display. When the overvoltage limiting component is heated above a certain minimum temperature, expansion of the thermally activatable, endothermic material produces a change in position of the display element whose magnitude is a measure of the heating of the overvoltage limiting component.
摘要:
Process for producing a pressure vessel having an enveloping body which occupies an arch shape in its predetermined installation position. The enveloping body has pillow-shaped portions which are connected to one another by stamped transitions at the inner diameter area of the enveloping body. The enveloping body for the intended installation position is placed with its inner diameter area one-sidedly on a die having a raised wedge-shaped profile. A designated outer diameter area of the enveloping body contacts a supporting surface, and the enveloping body is filled with a pressure medium so that the enveloping body is tensioned on the die and, in so doing, is plastically deformed in the area of the wedge-shaped profile.
