This paper introduces the functioning of crow ba r circuit and its realization method, introduces different kinds of crowbar cir cuit and different working mode.
Through disassembling,testing and renovating the original control system,gradually resumed LOCAL,REMOTE system and CROWBAR system,at last successfully accomplished control system united experiment between REMOTE unit and LOCAL unit.
The reaction of molten Al-2.5 pct Li alloy or pure aluminum with water was studied by the exploding wire technique incorporating a crowbar switch current interruptor and an inductive energy store.
During this process, the stiff hamulus (the pollinia stalk protruding prominently towards the lip) acted as a crowbar when it was brushed downwards by the toppled fly and lifted the pollinia out of the anther.
The second version employs the crowbar regime and makes it possible to form unipolar current pulses with a 190-kA amplitude and a 500-μs duration in the load circuit.
