1 of the rectifier transformer is connected to the electrical isolation between thevoltage of AC/DC power converters, voltage conversion required for load andoffered load and power supply side;
2 according to the ICE-146, 2/8/10/15/19 circuit, only one of the two secondary side winding of the transformer (connection group is DYN11) is suitable for running at 6 pulse rectifier;
3 according to the ICE-146, 3/4/5/6/11/12/16/1718 circuit, transformer with twotwo side winding (joint group DdOy11), electromagnetic decoupling, suitable foroperation in the 12 pulse rectifier, the rectifier 12 veined, composition as a result of the two bridge circuit, so the parallel connection, 30 phase.
Two, product features
The 1 insulating system conforms to the UL1446, also can design according to customer requirements;
Comply with H requirements or 2 temperature, insulation material with H class;
3 rectifier transformer consists of a polyester resin insoluble in the vacuumpressure impregnation (VPI), and then in the heat curing, heat curing, rectifier transformer is generally designed into natural air cooling, forced air cooling can be designed according to user requirements, the transformer external size and weight will be reduced, this time the air cooling device, ensure the transformeroperation (especially for large capacity transformer);
4 product testing: 100% product testing.
