Description

An outdoor busbar bridge lightning protection device

technical field

The utility model relates to the technical field of busbars, in particular to a lightning protection device for an outdoor busbar bridge.

Background technique

Busbar refers to the connection of voltage distribution devices at all levels in the substation, as well as the connection of electrical equipment such as transformers and the corresponding distribution devices, mostly bare wires or stranded wires with rectangular or circular cross-sections. The function of the bus is to collect, distribute and transmit electrical energy. The busbar is divided into hard busbar, soft busbar and closed busbar according to the structure. Lightning protection device refers to the sum of lightning terminals, down conductors, grounding devices, surge protectors (SPD) and other connecting conductors. Generally, lightning protection devices in buildings are divided into two categories: external lightning protection devices and Internal lightning protection device. The external lightning protection device is composed of the lightning terminal, the down conductor and the grounding device, that is, the traditional lightning protection device. The internal lightning protection device is mainly used to reduce the lightning current and its electromagnetic effect inside the building. For example, measures such as electromagnetic shielding, equipotential connection and installation of surge protector (SPD) are used to prevent the possible harm caused by the electromagnetic pulse of lightning strike, and the grounding The device is an important part of the lightning protection device. The grounding device discharges the lightning current to the ground, limiting the voltage of the lightning protection device to the ground from being too high. Except for the independent lightning rod, the lightning protection grounding device can be shared with other grounding devices on the premise that the grounding resistance meets the requirements.
