Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3, a relay station includes a control room 1, a protection isolation sleeve frame 10 wrapped with an iron net is disposed on the control room 1, an isolation chamber 5 is disposed in the control room 1, a protection electronic box 6 is disposed in the isolation chamber 5, a control cabin 7 is disposed in the isolation chamber 5, a relay station 2 is disposed in the control cabin 7, a duplexer 3 is disposed on the relay station 2, a lightning rod 11 is disposed in the protection isolation sleeve frame 10, a grounding tube 12 is connected to a bottom end of the protection isolation sleeve frame 10, an antenna fixing table 8 is disposed on the control room 1, a wire adapter 4 is disposed in the middle of the control cabin 7 in the control room 1, and an antenna 9 connected to the wire adapter 4 is disposed in the antenna fixing table 8.

Through the mode, the relay station 2 can not burn out internal elements due to induced lightning formed by direct lightning in thunderstorm weather, and meanwhile, the lightning rod 11 in peaceful weather is connected by the feedback loop to also serve as the auxiliary antenna 9 for receiving signals, so that the problem that the signals of the antenna 9 are influenced by a frame body formed by the lightning rod 11 is avoided.

Please refer to fig. 3, a fuse isolation switch 14 is disposed in the protection box 6, and a ground resistor 13 is connected to a wire of the ground tube 12 to ensure a feedback loop, so that the circuit can be disconnected after the electrostatic induction lightning current is formed, the ground resistor 13 can prevent the signal from directly losing to the ground when the fuse isolation switch 14 is not disconnected, and the signal can be used as the ground resistor 13 to introduce the lightning current to the ground after being disconnected.

Please refer to fig. 3, the ground resistance 13 is required not to be larger than 10 ohms, and according to the national lightning protection safety requirement standard, the time of the resistance value is prolonged due to the current flowing into the ground, the lightning can preferentially select the conductor with smaller resistance value, and the lightning rod 11 will not play any role to bring harm to the equipment.

Referring to fig. 1, the insulation material is filled between the iron net and the lightning rod 11 in the protective isolation sleeve 10, and the insulation material is not in contact with the lightning rod 11, so as to isolate the lightning rod 11 from the iron net and prevent the iron net and the lightning rod 11 from forming an integral body, which makes the effect of isolating the electromagnetic field ineffective.
