Electrical equipment protecting method of co-location house of communication base station when being struck by lightning

Abstract

The invention discloses an electrical equipment protecting method of co-location houses of a communication base station when being struck by lightning. The electrical equipment protecting method includes: firstly, electrically connecting earthing bars of distribution boxes of houses co-locating with the communication base station with an earth screen of the communication base station, and adding lightning protection devices on power lines in the distributing boxes, secondly, adding coaxial-cable lightning protection devices on cable television lines in the houses and earthing earth leads of the coaxial-cable lightning protection devices nearby, and thirdly, separating lightning protection devices of computers in the houses into two conditions: 1, adding a signal lightning protection device on a distributing box at the front end of a modem when each computer gets access to the Internet in an asynchronous transmission mode through the modem, and 2, adding a signal lightning protection device on an exchanger at the front end of a computer network cable when each computer gets access to the Internet through optical fibers in housing estates or building corridors, and electrically connecting the earth leads of the signal lightning protection devices with the earth screen of the communication base station under the two conditions. The electrical equipment protecting method has the advantages that lightning current flowing in along the power lines or the cable television lines can be bled through the lightning protection devices, so that the electrical equipment in the houses can be protected.

Description

technical field [0001] The invention relates to the lightning protection of a building co-located with a mobile communication base station, in particular to a method for protecting electrical equipment of a co-located building when the communication base station is struck by lightning. Background technique [0002] At present, many communication base stations of operators are rented houses in residential areas or residential areas. In order to protect the safety of base station equipment, each operator usually carries out special lightning protection design for communication base stations. The equipment in communication base stations has various lightning protection However, the electrical equipment of the residential buildings co-located with it cannot be guaranteed because there are no lightning protection facilities. When the base station is struck by lightning, due to the existence of the antenna of the communication base station, the lightning electromagnetic field gene...

Problems solved by technology

[0002] At present, many communication base stations of operators are houses in rented communities or residential areas. In order to protect the safety of base station equipment, each operator usually carries out special lightning protection design for communication base stations. The equipment in communication base stations has various lightning protection However, the electrical equipment of the residential buildings co-located with it cannot be guaranteed because there are no lightning protection facilities.

When the base station is struck by lightning, due to the existence of the antenna of the communication base station, the lightning electromagnetic field generated when the lightning current passes through the iron tower and the secondary effect of the counterattack of the ground potential, the lightning passes through the power distribution system in the house, CCTV cables, and various network cables Cause damage to indoor electrical equipment in residential houses co-located with communication base stations
