Product Overview
Advanced SF6 Insulated Resonant Reactor Technology
Traditional high voltage reactors usually require large installation space due to insulation limitations. The SF6 insulated design significantly improves insulation capability while reducing equipment size.
The fully enclosed SF6 structure provides:
- High dielectric strength
- Compact equipment configuration
- Stable electrical performance
- Reduced environmental influence
- Reliable long-term operation
This design is especially suitable for modern high voltage laboratories and power equipment testing facilities.
Working Principle
Variable Frequency Resonant Testing Technology
The SF6 FM Resonant Reactor works together with a variable frequency power supply to form a series resonant test system.
During operation, the inductive reactance of the reactor and the capacitive reactance of the tested equipment create resonance at a specific frequency. At the resonant point, the system can generate high AC test voltage with relatively low power input.
This technology is widely applied for testing large-capacitance electrical equipment where conventional test transformers may require higher power capacity and larger dimensions.
