Direct lightning protection device of shipborne short-wave communication system and protection assessment method thereof

Abstract

The invention discloses a direct lightning protection device of a shipborne short-wave communication system. The device comprises an external insulating cylinder, an external upper electrode, an internal upper electrode, an external lower electrode and an internal lower electrode, wherein the external insulating cylinder is provided with a hollow cavity, and the top end and the bottom end of the external insulating cylinder are provided with open holes; the internal upper electrode and the internal lower electrode are respectively positioned above and below the cavity of the external insulating cylinder; one end of the external upper electrode is inserted into the cavity and is connected with the internal upper electrode; one end of the external lower electrode is inserted into the cavityand is connected with the internal lower electrode; the external upper electrode and the internal upper electrode are respectively provided with air outlet channels which communicate with each other;and the external lower electrode and the internal lower electrode are respectively provided with air inlet channels which communicate with each other. The present invention further discloses a protection assessment method of the direct lightning protection device of the shipborne short-wave communication system. The direct lightning protection device of the shipborne short-wave communication system solves the problem that direct lightning strike is possible due to the fact that the whip antenna in the short-wave communication system is located outside the protection range of the lightning rodon the ship.

Description

technical field [0001] The invention relates to the technical field of lightning protection, in particular to a direct lightning strike protection device for a ship-borne short-wave communication system and a protection evaluation method thereof. Background technique [0002] In general, use the ship's mast to install a lightning rod, so that some electronic equipment on the mast and deck are placed within the protection range of the lightning rod, reducing the probability of being directly struck by lightning. However, due to the constraints of overall resources, lightning rods often have limitations in height, weight, and quantity. As a result, some shipboard equipment, especially whip antennas in various short-wave communication systems, are not within the protection range of lightning rods and are still threatened by direct lightning strikes. In the event of a lightning strike, the instantaneous large lightning strike current will be conducted along the antenna to the ba...
