A kind of installation and construction technology of grounding copper cable

Abstract

The invention provides an installation and construction technology of grounding copper cables. The technology comprises the steps of: installing and positioning the grounding copper cables; installing a vertical grounding electrode; burying the grounding copper cables; laying the grounding copper cables on various layers of a building; laying a roof lightning protection belt; and carrying out indoor grounding network construction. The welding and connecting technology in the indoor grounding network construction step is an exothermic welding process and specifically comprises the following steps of: selecting a proper mold according to the joint form of the grounding copper cables; cleaning the connection positions of the grounding copper cables; adding reaction powder; and carrying out ignition for welding the cables and cleaning the mold. The same or different metals of copper and copper, copper and steel and the like can be completely fused by the exothermic welding process; and real molecules combination is achieved, so that a lightning-proof grounding device becomes a permanent maintenance-free device; the grounding protection technology provided by the invention is very perfect; the leakage damage of equipment is effectively prevented; the manpower resource is saved; and the time limit for a project is shortened.

Description

technical field [0001] The invention belongs to the field of building installation engineering, and in particular relates to an installation and construction process of a grounding copper cable. Background technique [0002] The grounding device is also called the grounding integration device: a device that forms an electrical connection between electrical equipment or other objects and the ground. The purpose of connecting the electrical system to the earth. The metal object that is in direct contact with the earth to achieve electrical connection is a grounding electrode. It can be an artificial grounding electrode or a natural grounding electrode. The grounding electrode can be given a certain electrical function, such as for system grounding, protective grounding or Signal grounding, the grounding busbar is the reference potential point of the electrical installation of the building, through which the part that needs to be grounded in the electrical installation is conn...

AI Technical Summary

Problems solved by technology

In my country's North China, East China and South China and other lightning-prone areas, the grounding system of construction and installation projects often uses copper materials as ground electrodes, ground busbars and lead wires, etc., and the traditional welding connection method between copper materials and ground bodies of different materials There are defects such as insufficient electrical conductivity (current capacity) and low strength
