| titleOfInvention | Overvoltage protection device for general applications |
| abstract | The inventive overvoltage protection device for general applications enables effective overvoltage protection in zero- and low-frequency message, data transmission, measuring, control and regulating systems as well as in electric power generation, distribution and consumer systems with DC or AC voltage up to 380 Vrms. The overvoltage protection device essentially consists of a gas-filled surge arrester as coarse protection, a zinc oxide varistor as fine protection and a component connecting both in the form of an ohmic or inductive resistor to ensure the energy flow in normal operation and for the distribution or partial absorption of the energy of the incoming overvoltage. If the operating voltage of the system to be protected exceeds the threshold voltage of the arrester, the coarse protection consists of a series connection of several arresters with high-impedance, parallel potential control resistors. A potential field of application is overvoltage protection in the entire DC or low-frequency operated low-voltage and heavy current technology. The overvoltage protection device according to the invention realizes the protection requirements of this technology against dangerous overvoltages to a far greater extent than previously known solutions.
