Lightening protection method and lightening protection feed between tower amplifier and base station

Abstract

The invention discloses a lightening protection method and a lightening protection feed between a tower amplifier and a base station. The lightening protection feed of the base station is provided with a lightening protection port, a radio frequency port and a DC input port respectively; the lightening protection port is connected with a radio frequency transceiver of the base station to prevent the radio frequency transceiver of the base station from being damaged by induction overcurrent and overvoltage; the radio frequency port is connected between the base station and the tower amplifier and is used for transmitting radio frequency signals of the base station and the tower amplifier; the DC port is connected with the tower amplifier and is used for transmitting DC of the tower amplifier; the lightening protection port and the radio frequency port adopts a high-pass filter circuit and a low-pass filter circuit, and the radio frequency communication signals are high-frequency AC signals and can only pass a high-pass filter channel at the radio frequency port; and low-frequency signals of lightening stroke can only pass a lightening branch at the lightening protection port so as to conduct discharge current to ground. The lightening protection feed adopts high-pass filtering and low-pass filtering, has wide frequency, small loss of voltage standing wave ratio, high isolation without signal interference, and is provided with an indicator light circuit to judge the DC supply condition.

Description

technical field [0001] The invention relates to a protection method and device for electrical equipment, in particular to a lightning protection method and a lightning protection feeder for transmission of radio frequency signals and direct current between a tower top amplifier for lightning protection of a mobile communication base station and a base station, and a lightning protection feeder.
