Abstract

The invention discloses a variable energy combination-type lightning grounding device, which is formed by at least more than two variable energy lightning grounding units in parallel. Each variable energy lightning grounding unit comprises an outer shell (1) and an inner core (2); a cavity (3) is arranged between the outer shell (1) and the inner core (2); the cavity (3) is filled with an electrolyte combination, and an insulated cover plate (5) is adopted to package the cavity in the grounding device. According to the variable energy combination-type lightning grounding device, charging and discharging performance of a battery is provided, no polarity requirements exist, charging and discharging can be carried out in both positive and negative directions, lightning and impact of pulses of different polarities can be matched, the inner resistance is small, low voltage is tested to be smaller than 0.6 ohm, high voltage is tested to be smaller than 0.06 ohm, variable energy is firstly absorbed and then released, inverse voltage is little and even non, lightning protection effects are excellent, the structure is simple, maintenance is not needed, and the device can be widely applied to telecommunications, power, communication, mobile equipment, transportation, and other grounding systems.

Description

Technical field [0001] The invention relates to a lightning protection and lightning protection device, in particular to a variable energy combined lightning protection grounding device. Background technique [0002] Thunder and lightning are a natural phenomenon in nature. When lightning occurs, it will generate super current and voltage, which can easily cause damage to people's lives and property. The grounding resistance of the lightning protection ground wire in the prior art needs to be designed according to the topography, landform and geological conductivity of the construction site, and it needs to pass repeated tests. It is difficult to produce a suitable lightning protection ground wire in some geological and landforms. The lightning protection effect is affected, and the construction period is long. It is difficult to achieve uniform standards for lightning protection ground lines, and it is not convenient for mass and large-scale production. Especially in the proces...
