The invention discloses a high-power radio frequency antenna thunder-lightning protection device which is arranged between a feeder line and the ground, wherein the feeder line is used for connecting an antenna and a transmitter. The high-power radio frequency antenna thunder-lightning protection device concretely comprises a seal metal box, a discharge ring and a discharge block. Coaxial sockets which are respectively connected with the antenna and the transmitter are arranged on two opposite side surfaces of the seal metal box. The discharge ring is arranged in the seal metal box and is coaxially and fixedly arranged on a metallic conductor rod which connects two conductors in the coaxial sockets. The discharge block is arranged in the seal metal box and is in electric connection with a box body of the seal metal box, and can slide parallel to the metallic conductor rod. An inclined plane is arranged on the discharge block, and a discharge gap is formed between the inclined plane and the discharge ring. The high-power radio frequency antenna thunder-lightning protection device is small in size, stable in thunder-lightning protection indicator, good in thunder-lightning protection performance, capable of bearing big discharge currents and repeated discharge, and not being damaged, convenient to install, and suitable for high-power devices and broadband, and good in high frequency response under short waves.
Description
technical field [0001] The invention relates to a lightning protection device, in particular to a high-power radio frequency antenna lightning protection device. Background technique [0002] Radio frequency transmission is mainly used in broadcasting and radio communication. In order to improve the signal propagation effect and expand the coverage, the transmitting antennas are generally installed in open places or high places, which are prone to lightning strikes. In order to prevent the transmitting equipment from being attacked by lightning and ensure the normal operation of the transmitting equipment, protective measures must be added to the antenna end of the transmitting equipment. For high-power transmitters, the existing lightning protection device is to set a high-voltage discharge device between the radio frequency antenna and the ground, such as figure 1 shown. Wherein, the high-voltage discharge device is a pair of discharge balls 2a and 2b arranged between th...
