Summary of the invention
When the present invention needs two rectifier cubicles series connection to meet job requirement in order to solve and the cost bringing increases and the low problem of rectifier cubicle utilance, provide a kind of novel rectifying device cabinet.
The present invention adopts following technical scheme to realize: a kind of novel rectifying device cabinet, comprise cabinet, in cabinet, there is rectifier transformer, first three-phase 6 pulse wave rectifier bridges and second three-phase 6 pulse wave rectifier bridge, the input of one of them three-phase 6 pulse wave rectifier bridge and the secondary side star winding of rectifier transformer are connected, the input of another three-phase 6 pulse wave rectifier bridges and the secondary side delta windings of rectifier transformer are connected, 1 of two three-phase 6 pulse wave rectifier bridges, 3, 5 brachium pontis are all fixed on the front reveal of cabinet, 2 of two three-phase 6 pulse wave rectifier bridges, 4, 6 brachium pontis are all fixed on the rear reveal of cabinet, a common anode utmost point group of first three-phase 6 pulse wave rectifier bridges and a common anode utmost point group of second three-phase 6 pulse wave rectifier bridge form one group of rectistack, a common cathode group of first three-phase 6 pulse wave rectifier bridges and a common cathode group of second three-phase 6 pulse wave rectifier bridge form one group of rectistack, be in cabinet, to have six groups of rectistacks (each three-phase 6 pulse wave rectifier bridge has three common anode utmost point groups and three common cathode groups), common cathode on first three-phase 6 pulse wave rectifier bridges is extremely extremely connected with the common anode on second three-phase, 6 pulse wave rectifier bridges.
Common cathode on first three-phase 6 pulse wave rectifier bridges is extremely extremely connected with the common anode on second three-phase, 6 pulse wave rectifier bridges, realized the series connection of two three-phase 6 pulse wave rectifier bridges, the voltage of two three-phase 6 pulse wave rectifier bridge outputs is added, the rated output voltage U1 that rectifier cubicle output is two times, can meet the operational environment of two times of rated voltage U1, and do not need to prepare in addition a rectifier cubicle, job costs have been saved, also can not reduce the utilance of rectifier cubicle, when if operating voltage requires to be rated voltage U1, common anode on first three-phase 6 pulse wave rectifier bridges is extremely extremely connected with the common anode on second three-phase, 6 pulse wave rectifier bridges, common cathode on second three-phase 6 pulse wave rectifier bridge is extremely extremely connected with the common cathode on second three-phase, 6 pulse wave bridges, realized the parallel connection of two three-phase 6 pulse wave rectifier bridges, the output of rectifier cubicle is rated voltage U1, in the present invention simultaneously, six common anode utmost point groups and six common cathode groups of two three-phase 6 pulse wave rectifier bridges have been formed to six groups of rectistacks, facilitated and changed and maintenance.
The present invention has following beneficial effect:
1) on space, in some specific operation environment, the separate unit rectifier cubicle of new construction can substitute two rectifier cubicles of existing structure and power to power consumption equipment, can save a rectifier cubicle at the area occupied of electric substation, saves usage space;
2) economically, the cost of supposing the major loop (diode rectification heap) of new construction separate unit rectifier cubicle and two rectifier cubicle major loops (diode rectification heap) of existing structure is identical, the existing structure separate unit rectifier cubicle cost total price 120,000 of take is example, existing structure separate unit rectifier major loop cost accounts for total cost 50%, 60,000 yuan, remainder cost is 60,000 yuan, therefore learn that two rectifier cubicles of the relative existing structure of new construction separate unit rectifier cubicle can save 60,000 yuan of manufacturing costs, greatly promoted economic benefit;
3) integrated, when two rectifier cubicles of existing structure need connection in series-parallel to switch in special operation condition, need to increase external switch conversion equipment, significant wastage space and cost payout, and all functions of two rectifier cubicles of the integrated existing structure of new construction separate unit rectifier cubicle and external conversion switch, there is higher Integrated Trait;
4) application, come into operation in this new construction rectifier cubicle Yi Hitachi Yongji company production site experiment station, and application performance is respond well, is applicable to the experiment station of space compactness.
