Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
In order to make those skilled in the art be better understood from this utility model scheme, below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out clear, complete description.
As it is shown in figure 1, a kind of Novel pulse electrical power control cabinet, including input circuit 1, the preposition booster circuit of pulse 2, impulse commutation filter circuit 3, pulse generation accumulator 4, pulse boostering circuit 5, pulse sampling circuit 6 and this bulk electric field 7；The preposition booster circuit of described pulse 2 is connected to input circuit 1, described impulse commutation filter circuit 3 is connected to the preposition booster circuit of pulse 2, described pulse generation accumulator 4 is connected to impulse commutation filter circuit 3, described pulse boostering circuit 5 is connected to pulse generation accumulator 4, described pulse sampling circuit 6 is connected to pulse boostering circuit 5, described bulk electric field 7 is then connected to pulse sampling circuit 6, thus constitutes major loop；Concrete, described input circuit includes one group of three-phase electricity source 8, main circuit breaker QF and at least three group fuse wire FU；The preposition booster circuit of described pulse 2 includes at least three group Group of Silicon Controlled Rectifier SCR and three-phase transformer TM；Described impulse commutation filter circuit 3 includes three-phase commutation bridge and is connected to the filter capacitor C1 of three-phase commutation bridge；Described pulse generation accumulator 4 includes storage capacitor C2, I GBT power tube, controls switch and diode；Described pulse boostering circuit 5 includes pulse transformer；Described pulse sampling circuit 6 includes coupling electric capacity C3 and being connected to the resistance R of this coupling electric capacity C3.
