Rale's workshop on CWIEME 2008 in Chicago
This Rale workshop approaches the design of transformers for a
Transformer Manufacturer from point of view of a buyer and/or user
of transformers. To demonstrate these applications, Rale selected
about 20 design examples as follows:
- Designing inherently short-circuit-proof, potted safety
transformers 12V, 0.166A in accordance with IEC 61558
- Designing inherently current limited, potted safety
transformers 10V, 5A in accordance with UL 1585 Class 2
- Designing inherently current limited single phase
transformer 24V, 100A with integrated inductor
- Designing high voltage ,potted transformers 10kV, 0.1A,
1500Hz
- Designing mixed operation mode transformer, 230V/115V, 10A
in autotransformer and 230V/115V, 10A galvanic separated
connection
- Designing three phase autotransformer, for 3x400V/3x380V,
10kVA output power and 25% one phase unsymmetrical load
- Designing three phase, low inrush current universal
autotransformer for 3x208V/120V, 50/60Hz, 9A
- Designing rectifier transformer for battery charger 6Vdc,
40dc
Designing rectifier transformer for welding with 26Vdc, 200Adc
Designing the audio transformer for loudspeaker 25W, 16_Ohm
Designing flyback transformer for capacitor charger 10kVdc, 0.1
µF, 50W
- Designing a 500 kVA, 60Hz, K-Factor, three phase dry
transformer with cooling channels?
- Designing a 3 phase, 50/60Hz rectifier transformer (YYD to
supress 5. and 7. harmonics) with 2 parallel connected bridge
rectifiers, for Udc = 400V and Idc = 1000A
- Designing a 12Vdc, 30kAdc Rectifier Transformer
- Designing a 1600kVA/35kVA, 50Hz Distribution Oil
Transformer
- Designing Water Cooled Inverter Filter Choke, 0.5mH,
600Arms, 60Hz
Power Factor Correction Chokes
- Commutation Chokes
Smoothing Chokes
LC-Filter Chokes
Current Compensated Chokes
The concept is to assist the Transformer Manufacturers to
incorporate transformer designs as an integral part their business
and also for the Transformer Manufacturers to get a better overview
about new applications that they could be easily integrated in their
production using Rale's design software. For this reason Rale has
included very powerful design guidelines, for instance relating to
water cooling, high voltage spacing, etc.
