发明名称 A device protecting against high frequency overvoltage
摘要 <p>The subject of the invention is a device protecting against high frequency overvoltage, comprising a solenoid conductive connector (1), designed for suppressing high frequency current and voltage components, applicable in the protection of electric equipment working in electric power networks, and especially in electric substations. The device protecting against high frequency overvoltage comprises a conductive connector (1) designed to be connected in series into the current path of an electric power system as a section of the current path. The conductive connector (1) contains an induction coil (2) connected in parallel with a resistor (3), located in a common insulating housing (8). The inventive device is characterized in that the induction coil (2) through one of the external conductive terminals (6) or (7) is connected with a capacitive device (14) or (14') of the electric power system, which causes that the conductive connector (1) functions as a low pass filter, whereas the other external conductive terminal (6) or (7) respectively, is connected with an auxiliary device (16), connected into the current path circuit.</p>
