摘要： Exemplary embodiments are directed to a device with overvoltage protection that includes a varistor which can be connected by a first connection via a first line to high-voltage potential in a circuit arrangement, while a second connection is connected to ground via a second line. Furthermore, an additional impedance is provided, which can be connected between the second connection and ground or the first connection and the high voltage, or is mounted fixed in this position. The corresponding line can be interrupted by a switching arrangement. In order to test the withstand voltage of the circuit arrangement, at least one of the first and second line is interrupted and an additional impedance is inserted. A test voltage is applied to the circuit arrangement. After the overvoltage test, the interruption in at least one of the first and second lines is removed again.

摘要： The manufacturing method for an electroceramic component (1), for example a varistor (1), comprises a laser irradiation of a part (5; 6) of the surface of an electroceramic body (2) before a metallization (3; 4) is applied to the part (5; 6) of the surface. By means of the laser irradiation it is possible to produce a micro-roughness and/or a chemical modification of the surface which permits good adhesion of the metallization, and it is possible to reduce or eliminate areas of unevenness or waviness of that part (5; 6) of the surface of the electroceramic body (2) which is to be metallized. In addition, improved transverse conductivity can be produced, by virtue of which a low contact resistance and a very homogeneous current distribution is achieved, in particular near to the metallization (3; 4). In addition it is possible to remove residues which originate in particular from a sinter support or from the application of a passivation layer. After the laser irradiation, the electroceramic body advantageously has a border (9) which adjoins the part (5; 6) of the surface and which is not laser-irradiated. The laser beam can advantageously be pulsed and focused.

摘要： The electrical resistance element (10) includes a resistance body (3), which is arranged between two plane-parallel, pressurized electrodes (1, 2), has PTC behavior and comprises a polymer matrix and two filler components of electrically conducting particles embedded into the polymer matrix (4).When a short-circuit current occurs, the resistivity of the resistance body (3) changes abruptly above a temperature limit value in a surface layer resting on the electrodes and containing at least a first of the two filler components. A second of the two filler components is selected such that a composite material containing at least the polymer matrix and the second filler component has PTC behavior, with an abruptly changing behavior greater by at least one order of magnitude in comparison with the surface layer. At the same time, this composite material has a resistivity which is lower by at least one order of magnitude than a composite material formed by the polymer matrix and the first filler component.The resistance element has a high nominal current carrying capacity and can limit large short-circuit currents permanently.

摘要： A current-limiting component having an electrical resistance body arranged between two contact terminals. The resistance body contains a first resistance material having PTC behavior. Below a limit temperature, the first resistance material has a low cold resistivity and at least one current-carrying path extending between the two contact terminals. Above the limit temperature, the first resistance material has a high hot resistivity compared with its cold resistivity. The current-limiting component has uniform switching capability and high rated current-carrying capacity despite simple and inexpensive construction. The resistance body additionally contains second resistance material having a resistivity which is between the cold resistivity and the hot resistivity of the first resistance material. The second resistance material is in intimate electrical contact with the first resistance material and forms at least one resistance path connected in parallel with the current-carrying path.

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.
