Power is 160 to 6400 kW
Frequency is 0.5 to 10 kHz
Output voltage is 800 to 2000 V
Generator for supplying of induction heating and metal melting devices of ТПЧ type is designed for operation in electrothermal equipment systems. The converter can be supplied both alone for usage in the processing and in a set of the technological complex as well. High reliability, wide power range and relatively high output voltage are the features of thyristor converters.
6-, 12-, 18-pulse rectification systems are used for decreasing of influence to the circuit.
Manufacturing of converters with power, voltage and frequency characteristics different from standard ones are available on Customer’s demand. е.
All converters are completed with high quality thyristors of domestic development and manufacture.
Main advantages:
- High output voltage
- High resistance to short circuit under load
- High specific power rating
- High reliability and repairability (service life is 30 years, min, without overhaul)
- Digital control system
- Bilateral construction provides ease and serviceability.
Adjustment features:
- Wide range of output voltage is 20 to 100% vs rated one;
- Adjustment range of output load power is 3 to 100% vs rated one;
- Output parameters adjustment, including load frequency variation within +/- 20%, is carried out without switching in power circuit.
Microprocessor control system:
Generators of ТПЧ series fifth generation are equipped with new microprocessor control system and due to it performed the following:
- expansion of functional generator abilities;
- increasing of reliability;
- debugging facilitation;
- information about ТПЧ state is displayed on the control panel.
Complete equipment:
Generators can be supplied in different implementation:
- generator
- generator with integrated cooling system
- monoblock power supply unit (generator, capacitor bank and cooling system)
- generator with separate interface cabinet
- generator with separate cooling system cabinet
