Induction Heating & Melting Capacitors

3.6kV 8000kvar Medium Frequency Induction Heating Capacitor

Designed for medium frequency induction heating systems requiring power factor correction and voltage stabilization. Supports metal smelting, heat treatment, forging, and welding applications.

Product Overview

The RFM series delivers rated voltage of 3.6 kV with reactive power capacity of 8000 kvar, supporting medium frequency induction heating systems requiring power quality optimization.

The capacitor construction uses metallized polypropylene film dielectric with self-healing properties. The capacitor plays two main roles in medium frequency induction heating systems: improving the power factor of the power supply, compensating for reactive power, reducing harmonic components, and minimizing pollution to the power grid; and stabilizing power supply voltage, reducing voltage fluctuations, and ensuring stable operation of the medium frequency induction heating power supply. Through its capacitive characteristics, the capacitor forms a resonant circuit with the inductor element in the medium frequency power supply to achieve efficient energy transmission and conversion.

Three configuration options are available to accommodate different system requirements: single cooled-live case design with sub-sections (one terminal connected to casing), single cooled-isolated case design with sub-sections (all terminals isolated), and double cooled-isolated case design without sub-sections (all terminals isolated). This flexibility allows integration with various system grounding requirements and thermal management approaches.

Frequently Asked Questions

What is the difference between live case and isolated case configurations? +
In live case configuration, one terminal is internally connected to the capacitor casing, requiring the casing to be grounded. This design is typically used in systems where the capacitor is part of a grounded circuit. In isolated case configuration, all terminals are isolated from the casing, providing flexibility for floating or ungrounded system designs.
What is the difference between single cooled and double cooled configurations? +
Single cooled configuration uses one cooling system and includes sub-sections for internal fault isolation. Double cooled configuration provides enhanced thermal management with two independent cooling systems and no sub-sections, suitable for higher power applications requiring maximum heat dissipation capacity.
How does the capacitor improve power factor and reduce harmonics? +
The capacitor compensates for reactive power in the medium frequency induction heating system, improving the power factor of the power supply. This reduces harmonic components in the electrical system, minimizing pollution to the power grid and improving overall power quality for industrial operations.
What is the expected service life under continuous operation? +
Service life is influenced by operating temperature, voltage stress, and duty cycle. Under rated conditions with proper cooling, the design life exceeds 80,000 hours. Regular monitoring of capacitance and dissipation factor is recommended to track degradation and ensure continued voltage stabilization performance.
What metals can be processed using this capacitor? +
This capacitor is suitable for processing various metal raw materials including steel, copper, aluminum, and other alloys. Applications include melting, heat treatment (quenching, tempering, annealing), forging, and welding operations across diverse industrial sectors.
