Switching of load currents with vacuum interrupters and the resulting electrical life
2020 29th International Symposium on Discharges and Electrical Insulation in Vacuum (ISDEIV)(2021)
摘要
Although a considerable amount of effort is focused on the short circuit performance of vacuum interrupters, in practical applications these high current operations rarely or almost never occur. Instead, the bulk of operations in the field are switching load and/or capacitive currents. For load current switching, the low contact erosion and low metal vapor generation of the vacuum arc enables very...
