10kV fast vacuums switch [J] electrotechnics journals of structure, 2009,24 (11):It is special that 68-75.) discharge circuit has been carried out
Design, using pulse forming network (PFN), by controlling the triggering sequential of discharge module, is superimposed out required pulse current
Waveform, but limited by coil power supply power supply scale, complexity, larger limitation is faced in actual applications.
In summary, current single-impulse energisation mode, to the model of repulsive force mechanism energy-storage capacitor, capacity, charging
Voltage proposes higher requirement；Secondly, divide-shut brake coil is under single pulse excitation mode, and mechanical output characteristics is difficult to effective tune
