Detailed description of the invention
For making the purpose of this utility model embodiment, technical scheme and advantage clearer, new below in conjunction with this practicality
Accompanying drawing in type embodiment, is clearly and completely described the technical scheme in this utility model embodiment, it is clear that retouched
The embodiment stated is a part of embodiment of this utility model rather than whole embodiments.Based on the enforcement in this utility model
Example, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into
The scope of this utility model protection.
Fig. 1 is this utility model double-feed current transformer formula high-current generation device structural representation, as it is shown in figure 1, this enforcement
The device of example may include that
Chopper the 101, first catalyst 102, rectifier bridge 103, pre-charge resistance the 104, second catalyst 105, double-fed become
Stream device 106, reactor 107, PLC unit 108, host computer 109 and detected unit 110；Incoming power is L1、L2、L3。
Described chopper one end is connected with incoming power, and the other end is connected with described first catalyst, described first contact
The device other end is connected with described rectifier bridge, one end and described rectification bridging after described pre-charge resistance and the second catalyst parallel connection
Connecing, the other end is connected with described double-feed current transformer, and described PLC unit one end is connected with host computer, and the other end becomes with described double-fed
Stream device connects, and the outfan of described double-feed current transformer is connected with reactor, and the reactor other end connects detected unit.
Specifically, detector unit is slip ring or big chopper etc., and need to do the electricity of load test and temperature rise test
Gas equipment.Difference (in higher level or the subordinate of reactor in actual application) according to detector unit present position, can be optionally
Use at the leading-out terminal of reactor or the leading-out terminal of detector unit and connect wire by three-phase shortcircuit.The big electric current of double-feed current transformer formula occurs
The work process of device:
First, close chopper and the first catalyst, and device precharge loop is opened, when PLC detects that busbar voltage reaches
During to DC400V, close the second catalyst, and after DC bus-bar voltage is risen to DC510V, device uncontrollable rectifier loop is opened,
