Described copper bar seat comprises supporting plate and several conducting rods that are placed on the supporting plate, and described conducting rod penetrates the through hole of offering on the supporting plate respectively, and by the casting die that is positioned at the supporting plate both sides conducting rod is fixedly clamped on supporting plate, is connected to a fixed by several bolts between the casting die; Wherein, be positioned on the periphery at the conducting rod middle part and the position that contacts with supporting plate and be cast with insulating barrier.
Described conducting rod is one group with three, not on the same group and the spacing distance between the group greater than conducting rod distance each other in same group; Described insulating barrier is that the cross section is oblong cylinder body shape.
The utlity model has following beneficial effect:
1, reliability aspect: in interphase reactor half-wave shunt rectifier circuit,, cause the dangerous spot of several low-voltage high field intensities simultaneously because the existence of interphase reactor not only causes the low pressure busbar to move towards complicated.And the rectifier transformer of employing three-phase five-limb half-wave shunt rectifier circuit, structure is obviously simplified, thereby has improved reliability of products effectively.
2, loss aspect: because the existence of two return yokes, make frequency tripling harmonic flux or asymmetrically distributed zero sequence magnetic flux in the iron core that flow cycle be arranged, constitute the loop and needn't pass through structural members such as fuel tank, folder, thereby greatly reduce the supplementary load loss on these structural members.
3, consumptive material aspect: when direct voltage when 100V is following, both consume quite, along with the rising of direct voltage, the advantage that pentastyle is economized material is just obvious more.
4, outward appearance: interphase reactor formula shunt rectifier circuit, because interphase reactor will be set, whole appearance and modeling is difficult to satisfy the requirement of Artistic Design.The three-phase five-limb transformer is owing to cancelled interphase reactor, and the degree of freedom in total space has obtained great liberation, makes the outward appearance of entire product more attractive in appearance.
