Definitions
- the invention relates to a protective adapter for overvoltage protection of electrical equipment in a high-voltage power line, in particular a high-voltage overhead line.
- the invention also relates to a system with a high-voltage power line, electrical equipment and a protective adapter.
- High-voltage lines especially high-voltage overhead lines, represent a current standard for power transmission over long distances with as little loss as possible.
- the high-voltage lines are mostly arranged by means of overhead line masts at a distance from the ground. Due to the arrangement at appropriate heights, the high-voltage lines are exposed to an increased risk of lightning strikes and consequently require protection against overvoltages and damage to the high-voltage lines, adjacent equipment and devices.
- Surge arresters are known to protect against damage from overvoltages in high-voltage lines.
- a surge arrester within the scope of the invention is to be understood, for example, as known grounding points of overhead line pylons and / or surge arresters installed on the Ab spanning pylons and / or as surge arresters from an overhead line.
- the surge arresters are therefore divided into mast surge arresters and line surge arresters.
- These surge arresters are preferably installed in front of electrical equipment with changed electrical characteristics, in particular changed wave resistance.
- the common disadvantage of the classic surge arresters is that the greater the distance from a grounding point, the protection against damage from surge voltages, for example due to a lightning strike in High voltage power lines decreases.
- connection of high-voltage overhead lines to energy producers, energy consumers or substations usually provides for the connection of high-voltage overhead lines to electrical equipment in the form of gas-insulated conductors, gas-insulated bus ducts or cables.
