Abstract
The utility model discloses a thunder frequency impedance control unit, comprising band elimination filters and safety capacitors. The band elimination filters are connected in series in a power circuit, and the safety capacitors are connected in parallel in the power circuit. A lightning protection circuit comprises the thunder frequency impedance control units and a protected device. The thunder frequency impedance control units and the protected device are connected in series in the power circuit. Through methods of series connection and parallel connection, the band elimination filters and the safety capacitors form the thunder frequency impedance control unit which is simple and useful in structure. The thunder frequency impedance control units are connected in series in the lightning protection power circuit. When lightning invades, under the action of lightning frequency, impedance of the thunder frequency impedance control units rise synchronously with increase of lightning frequency, thus forming a large-power resistor. Under the action of lightning spectrum, impedance of the thunder frequency impedance control units and internal resistance of the protected device load form a tandem-type voltage dividing and current dividing protection device.
