英语翻译
The energy that must be absorbed (i.e.dissipated or recouped) during the interruption process can be significant,even with current limiting.Managing this system energy becomes the fundamental challenge that needs to be addressed by the breaker design.The components (e.g.MOVs,capacitors,dynamic brake resistors,etc) typically employed for energy dissipation and voltage limiting become as significant a part of the overall design (in terms of size and requirements) as are the main semiconductor switches.This fact has frequently been overlooked,resulting in several unsuccessful solutions that propose the use of simple semiconductor switches as breakers.
An example of the benefit of current limiting is shown in Fig.12.For a basic DC circuit with a clamp across the fast acting switch the family of curves shows the clamp energy that must be absorbed versus the available fault current in the circuit.A separate curve is shown for each instantaneous trip current of the switch.The circuit conditions are given in Table I.The time constant assumes a resistive + inductive circuit (e.g.no capacitors or active components).
The significance of the trend in Fig.12 is that as the trip current is lowered relative to the available current,a significant decrease in required energy dissipation will result.A solid state breaker can respond fast enough to achieve such energy reductions.The key design problem is to differentiate a fault from a load transient in order to avoid “false trips”.An understanding of load performance details and sensing techniques such as di/dt monitoring must be employed for reliable operation.This requires a system wide view and potentially all-inclusive control over a large part of the power distribution system breakers.This is not a practical requirement for a conventional industrial installation,but can be done given the closed power system on ships and the Navy’s trend toward more integrated ship control systems.
