Problems solved by technology

However, in the relevant grounding standards, there is no specific requirement for the type of grounding device, but only for the limitation of the grounding resistance value, which leads to various types and materials in actual engineering design and construction, so it is urgent to focus on existing independent lightning rods. Optimizing the type of grounding device

Abstract

The invention discloses a substation independent lightning rod grounding device and an optimization method, belongs to the technical field of electric power engineering grounding, and particularly relates to a substation independent lightning rod grounding device and an optimization method thereof. The basic form and the optimization form of the independent lightning rod are determined, safety verification is carried out on the distance between the grounding device and the main grounding grid, the connection mode of the independent lightning rod grounding device and the main grounding grid andthe distance requirement of the lightning rod and 35kV and below equipment are determined, and a basis is provided for design and construction of the independent lightning rod. And the probability ofcounterattack discharge to a protected object when the lightning rod is struck by lightning is prevented or reduced.

Description

technical field [0001] The invention belongs to the technical field of electric power engineering grounding, and in particular relates to a substation independent lightning rod grounding device and an optimization method. Background technique [0002] There are many types of lightning, not only direct lightning strikes, induction lightning, but also lightning intrusion waves that pass along the line. A lightning rod is a device that prevents direct lightning strikes. It uses the principle of tip discharge to guide the discharge of lightning to the earth to the lightning rod and discharge into the ground. That is to say, for the object protected by the lightning rod, the lightning rod can actually be called a lightning rod. It is more likely to be struck by lightning itself, so that the object protected by it is not struck by lightning. Therefore, the lightning protection principle of the lightning rod determines that the lightning rod will only choose to guide a strong dir...
