Abstract

The invention relates to a lightning protection device comprising at least one lightning rod, at least one grounding bar and a control device. Each lightning rod and the corresponding grounding bar are connected by a wire. The lightning protection device further comprises monitoring devices and auxiliary grounding devices, wherein each monitoring device is electrically connected with the corresponding lightning rod, the auxiliary grounding devices are buried in the earth, and each monitoring device is electrically connected with the corresponding auxiliary grounding device. Each monitoring device comprises a measurement unit and a power supply unit; the measurement unit comprises a processor circuit, a DC-AC conversion circuit and an operational amplifier circuit, and the DC-AC conversion circuit and the operational amplifier circuit are connected in series between the corresponding lightning rod and the corresponding auxiliary grounding device; and the power supply unit is connected with the measurement unit. The lightning protection device of the invention can monitor whether a lightning release path is normal or not in real time. When the lightning protection device fails, a warning can be issued to prevent personnel and property losses caused by the failure of the lightning protection device.

Description

technical field [0001] The invention relates to the technical field of lightning rods, in particular to a lightning protection device. Background technique [0002] In order to avoid damage and injury caused by lightning strikes, buildings, bridges, and even ships are generally equipped with lightning protection devices. Most of the lightning protection devices include one or more metal lightning rods and one or more grounding rods (or other similar equipment). These lightning rods will be electrically connected to form a network. The grounding rods are generally deeply buried in the ground. If there are multiple grounding rods, these grounding rods will also be electrically connected to form a network. The lightning rod or lightning rod network and the grounding rod or the grounding rod network are connected by one or more wires to form one or more conductive paths. Things are destroyed. Therefore, whether the lightning protection device can effectively provide protecti...
