Isolation floating-ground lightning protection method for small base station under unexposed environment

Abstract

The invention discloses an isolation floating-ground lightning protection method for a small base station under an unexposed environment. The method includes the steps of firstly, the communication transmission equipment, the building baseband unit and the power source distribution box of the small base station are mounted in a cabinet in an insulated manner; secondly, the grounding wires of the communication transmission equipment, the building baseband unit and the power source distribution box are connected in a floating-ground manner; thirdly, the power interface of the power source distribution box is electrically connected with an external power source through an isolation transformer and a differential mode lightning protector; the communication interface of the communication transmission equipment is connected with external communication through a communication cable and a photoelectric coupler; the differential mode lightning protector, the isolation transformer and the photoelectric coupler can be mounted inside or outside the cabinet, the differential mode lightning protector, the isolation transformer and the photoelectric coupler should be insulated from the cabinet when being mounted inside the cabinet, and the outgaining lines of the differential mode lightning protector, the isolation transformer and the photoelectric coupler should be insulated from the cabinet when the differential mode lightning protector, the isolation transformer and the photoelectric coupler are mounted outside the cabinet. By the method, the problem that the small base station is hard in lightning protection grounding under the unexposed environment is solved, safety and reliability of the small base station are increased greatly , and potential safety hazard is lowered.

Description

technical field [0001] The invention relates to a lightning protection and grounding method for a communication base station, in particular to an isolated floating ground lightning protection method for a small base station in a non-exposed environment. Background technique [0002] As a form of flexible site construction, small base stations are increasingly used by various operators, and are usually installed indoors, in buildings, or other indoor public places where it is difficult to find a grounding point. The construction of small base stations is relatively flexible, with relatively low requirements for addresses. It can be installed directly on the wall, which solves the problem of difficulty for operators to build stations. However, since small base stations are often built in non-telecom environments, they are relatively random and have no electrical connection. Therefore, there is no conventional lightning protection grounding method, so the lightning protection s...

The construction of small base stations is relatively flexible, with relatively low requirements for addresses. It can be installed directly on the wall, which solves the problem of difficulty for operators to build stations. However, since small base stations are often built in non-telecom environments, they are relatively random and have no electrical connection. Therefore, there is no conventional lightning protection grounding method, so the lightning protection safety of small base stations cannot be effectively guaranteed
