Advanced Magneto-Optical Arc Analysis

由分散发电和智能消费者组成的复杂电网在未来必须继续得到安全管理。真空断路器是现代电力传输的可持续解决方案。断路器的主要特点是将正常工作电流中断到短路等故障事件。在这里，真空灭弧在保持恒定介电强度的同时，为许多开关操作提供了节能触点系统和低腐蚀的优点。为了应对高压电网中较高的应力，需要对开关等离子体及其运动和脚点进行研究。MOLiBoA项目将真空断流器研究中的两种测量方法结合在一个通用测试装置中。采用了布伦瑞克工业大学的光学测量法和达姆施塔特工业大学的磁测量法。测量方法的有效性有待于通过同时比较来验证。短路分断时开关触点之间电流路径的位置是研究的主题。将根据记录的综合数据开发模型，并通过比较测量结果进行验证。目标是建立具有电、光、磁输入输出量及其在扰动影响下相互关系的宏观描述模型。这种系统的研究和国际交流将使真空灭流器在更高电压水平上的适用性成为可能。国际出版物报告了在特殊接触系统和个别试验容器上对真空等离子体的新的个别观察。复杂的实验程序和测量方法使得难以传递足够的信息，从而难以对实验结果进行必要的推广。因此，所获得的结果和基本的原始数据将以一种有待制定的数据标准提供给国际研究界。将创建一个原型数据库，其中将收集来自不同排列的交换等离子体的外观和动态。

Complex grids consisting of decentralized generation and smart consumers must continue to be managed safely in the future. Vacuum circuit breakers are a sustainable solution for modern power transmission. The key feature of circuit-breakers is the interruption of current from normal operating currents to fault events such as short-circuits. Here, vacuum interrupters offer the advantages of energy-efficient contact systems and low erosion for many switching operations while maintaining constant dielectric strength. To cope with the higher stresses in high-voltage networks, the switching plasma, its movement and its footpoints need to be studied. The MOLiBoA project combines two measurement methods from vacuum interrupter research in a common test setup. The optical measurement method of the TU Braunschweig and the magnetic measurement method of the TU Darmstadt are used. The validity of the measurement methods is to be verified by simultaneous comparison. The location of the current path between switching contacts during short-circuit breaking is the subject of the investigation. A model will be developed from the combined data recorded and validated by comparing the measurements. The goal is a macroscopic description model with electrical, optical and magnetic input and output quantities as well as their interrelationships under disturbing influences. This systematic investigation and international exchange will enable the applicability of vacuum interrupters at higher voltage levels. International publications report on new individual observations of vacuum plasmas on special contact systems and individual test vessels. Complex experimental procedures and measurement methods make it difficult to pass on sufficient information and thus the necessary generalization of the experimental results. The results obtained and the underlying raw data will therefore be made available to the international research community in a data standard to be developed. A prototypical database is to be created in which the appearance and dynamics of the switching plasmas from different arrangements will be gathered.
