摘要： In a superconducting current limiter 1, in the limiting state pressure waves which may damage the superconductor are produced as a result of the evaporation of cooling liquid. According to the invention, the current limiter is not immersed in a cooling liquid, but rather is brought into thermal contact with a cooling fluid 22 which does not undergo a phase transition at over the operating temperature and therefore does not evaporate in the limiting state. A refrigeration reservoir 21, which may be the condensed phase of a gaseous cooling fluid or a cryogenic cooler, determines the operating temperature of the current limiter. One advantage is that it is now possible for a plurality of plate-like current-limiter modules 10, 10′ of unlimited size to be arranged next to one another in the cooling fluid 22.

摘要： The invention relates to a nonlinear electrical material with improved microvaristor filler (1′), to devices and electrical apparatuses comprising such nonlinear electrical material and to a production method thereof. According to invention, the filler (1′) comprises larger spherical particles (5) and smaller irregular particles (6) that are arranged interstitially and provide non-point-like and/or multiple contact areas (56, 56a, 56b, 66) owing to their irregular outer shape comprising edges and faces. Embodiments, among other things, relate to: spherical particles (5) being calcinated and broken-up to retain their original shape; irregular, spikly shaped, particles (6) obtained by calcinating or sintering and crushing or fracturing granules or blocks; and addition of a third filler fraction. Advantages, among others, are: higher filler contents, more and more durable inter-particle contacts (56, 56a, 56b, 66), enlarged effective micro-contact area, and improved electrical performance of the nonlinear electrical material.

摘要： The disclosure relates to an overvoltage protection means containing ZnO microvaristor particles for protecting electrical elements and a method to produce the means. Single microvaristor particles are placed in an arrangement having a monolayer thickness and are electrically coupled to the electrical element to protect it against overvoltages. Embodiments, among other things, relate to: 1-dimensional or 2-dimensional arrangements of microvaristor particles; placement of single microvaristors on a carrier; the carrier being planar or string-like, being structured, being a sticky tape, having fixation means for fixing the microvaristors, or having electrical coupling means. The monolayered overvoltage protection means allows very tight integration and high flexibility in shaping and adapting it to the electric or electronic element. Furthermore, reduced capacitance and hence reaction times of overvoltage protection are achieved.
