摘要:
A light sensor for recording the position of a light source includes a photo detector and a light modulator. The light modulator is configured to modulate the quantity of light hitting the photo detector based on an incident angle (α) of the light from the light source on the sensor.
摘要:
The invention pertains to a solar sensor that includes a first modulator that is transparent to electromagnetic waves within a spectrum, and an additional modulator that is at best slightly transparent to the electromagnetic waves within the spectrum. The additional modulator features a belt-shaped region of varying widths that is arranged on the outside of the first modulator and partially covers the first modulator, and a photodetector that receives the electromagnetic waves and is covered by the first modulator.

A surge arrester is described which includes at least two electrodes. At least one of the electrodes includes a ventilation channel. The internal area of the surge arrester is connected to an external area of the surge arrester via the ventilation channel, wherein the ventilation channel is closed by means of a fusible element. The fusible element is preferably arranged at that end of the ventilation channel which faces the external area of the surge element.

A surge arrester includes a gas-filled closed arrester body that is formed by a first annular ceramic body and two electrodes at a distance from one another. A second annular ceramic body is arranged in the interior of the arrester body and is at a distance from the first ceramic body and has a physical height that is less than the physical height of the first ceramic body.
摘要:
A device for protecting against lightning and overvoltages includes two electrodes closing off, in a gas tight manner, both end faces of a cylinder made of insulating material, and defining a discharge chamber in the interior of the chamber thus formed. At least one step is provided in the chamber in the contact area of at least one of the electrodes and the cylinder such that the chamber extends outwards past the internal wall of the cylinder.
摘要:
An overvoltage arrester includes at least two electrodes and a melt element that connects one of the electrodes to an outer terminal of the overvoltage arrester. An extinguishing device is designed to extinguish an electric arc.
