Traction convertor out enters back into a secondary side winding (1.1 to 1.2) of tractive transformer while returning to current transformer, by QS1.2
Direct current incoming line is drawn from current transformer afterwards enters second secondary side winding (2.2 to 2.1) of tractive transformer and returns to unsteady flow
In device.
As shown in Fig. 2, by taking 7 vehicles as an example, after the input cable of 7 vehicle current transformers takes electricity from 7 vehicle direct current bow nets under DC mode
The series connection that 6 vehicle tractive transformers carry out first secondary side winding is led to from current transformer, the rear 7 vehicle current transformers that return are shorted route
(QS1.2 is closed to be formed) is again introduced into the series connection that 6 vehicle tractive transformers carry out second secondary side winding, is finally re-fed into current transformer
Intermediate dc circuit main track, then 7 vehicle current transformers input cable bridges 4 times between 6,7 vehicles, and single bridges length normally about 25
Rice, then always bridging length needs about 100 meters.Similarly 8 vehicles input cable bridged 4 times between 6,7,8 vehicles, between three vehicles single across
About 50 meters of spreading degree, then always bridging length needs about 200 meters, and train 1,2 vehicles are arranged symmetrically with 8,7 vehicles respectively, inputs cable
