Circuit breakers are important components in the electrical power supply grid. The maintenance of high voltage gas circuit breakers requires high personnel as well as monetary efforts for the asset operator. Furthermore, a faulty reassembly of the circuit breaker during maintenance can lead to a circuit breaker failure during operation. For this reason the maintenance strategy changed from a periodic...
A key challenge for future switching technologies, especially in the context of the substitution of the strong greenhouse gas sulphur hexafluoride and the ongoing development of DC grids, is the increase of the contact opening velocity within switching devices. Thus, in this contribution a compact helical coil operating mechanism is developed and first experimental investigations are performed to...
The maintenance of high voltage gas circuit breakers requires high personal as well as monetary efforts for the asset operator. Furthermore, a faulty reassembly of a circuit breaker during maintenance can lead to a circuit breaker failure during operation. One possibility to reduce those efforts as well as the failure risk is the application of non-invasive diagnostic techniques. This research work...
