Abstract

The invention relates to a lightning protection device for a control building. The lightning protection device comprises a building body which is provided with a top surface and is provided with outer walls on the periphery, and precision instrument equipment, a power supply line and a signal line which are arranged in the building body, and is characterized by further comprising a lightning receiving belt frame arranged on the top surface, a lightning receiving net connected with the lightning receiving belt frame, a trench arranged on the ground and located on the outer side of the outer wall, a closed grounding grid arranged in the trench, and a plurality of downleads laid along the outer wall and provided with transverse sections connected with the closed grounding grid and arranged at the lower ends of the downleads, wherein the upper ends of the downleads are connected with the lightning receiving belt frame, and the downlead is made of phi 16 hot-dip galvanized round steel. The lightning protection device for the control building can shunt the voltage of direct lightning, protect the stability of the ground potential of a ground grid in the building, and isolate the magnetic field of a downlead, so that a metal pipeline in the building does not generate large induced overvoltage so as to protect precise electronic instruments and equipment in the building from lightning disasters.

Description

technical field [0001] The invention relates to the technical field of electric equipment, in particular to a lightning protection device for a control building. Background technique [0002] Thunder and lightning disasters are one of the most serious natural disasters that threaten human beings. Lightning is extremely destructive. The intensity of lightning is as high as one billion volts, and the instantaneous current can be as high as hundreds of thousands of amperes. The destructive consequences caused by lightning strikes are reflected in: equipment damage, casualties; equipment or component life reduction; transmitted or stored signals and data are interfered or lost, and even cause electronic equipment to malfunction and paralyze or the entire system stops. The building lightning protection system can be obtained from a residential building lightning protection system disclosed in the utility model of Chinese Patent Application No. 201620602003.7; The material steel ...
