Abstract

The present invention relates to a lightning arrester device with an aging determination unit (1), comprising a lightning arrester (VAR) and an aging determination unit (1), the aging determination unit (1) has a first temperature measurement unit (S1) that detects the thermal state of the arrester (VAR), the aging determination unit (1) also has a storage unit (MEM) and an evaluation unit (CPU),the storage unit (MEM) stores aging data corresponding to the relationship between energy input and temperature characteristics of the arrester type, the first temperature measuring unit (S1) measuresthe temperature characteristics of the arrester (VAR) corresponding to the energy input, and the evaluation unit (CPU) obtains relevant aging data according to the measured temperature characteristics corresponding to the energy input, and then determines the aging degree of the lightning arrester (VAR).

Description

technical field [0001] The invention relates to a lightning arrester arrangement with an aging determination unit. Background technique [0002] Overvoltage protection devices are used in many areas of electrical engineering to protect systems or equipment from overvoltage events. These overvoltage protection devices are usually connected in parallel with the system / equipment to be protected. [0003] However, it is pointed out here that these overvoltage protection devices are subject to aging processes. An important factor of aging is given by the derivation of the overvoltage event itself. [0004] Therefore, the function / performance of the overvoltage protection device should be checked from time to time. [0005] In many areas, overvoltage protection devices are no longer easily accessible after installation. At this point, mention should be made of the use of overvoltage protection devices in offshore wind turbines or in control cabinets. [0006] Testing is often...
