1000Hz High Voltage Induction Heating Water Cooled Capacitor

Designed for high-frequency and high-power applications requiring fast and uniform heating. Supports power electronics, new energy, industrial automation, and aerospace industries.

Product Overview

The RFM series delivers high-frequency performance at 1000 Hz with water-cooled thermal management, supporting high-power induction heating applications requiring fast and uniform heating.

The capacitor construction uses metallized polypropylene film dielectric with self-healing properties. Advanced induction heating technology combined with precision water cooling systems enables handling of high-frequency and high-power applications. Using 1000 Hz high-frequency current, eddy currents are generated inside the capacitor through electromagnetic induction to achieve instant and deep heating effects. This technology improves heating efficiency, reduces energy loss, and ensures energy utilization compared to traditional heating methods.

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.

Installation & Operation Notes

Cooling Water Quality

Use deionized or softened water with conductivity below 10 µS/cm to prevent galvanic corrosion within the cooling channels. Maintain pH between 6.5 and 8.5. Filtration to 50 µm is recommended.

Water Flow Requirements

Flow rate depends on specific power rating and ambient conditions. For standard applications, flow rate of 4-6 L/min per 100 kvar is typical, with inlet temperatures between 15°C and 35°C. Detailed cooling requirements provided with each unit.

Mounting Orientation

Install with cooling ports horizontal to allow air purging during initial fill. Vertical mounting requires careful venting procedures to ensure complete water circulation.

Electrical Connections

Torque bus bar connections to specified values to minimize contact resistance. Loose connections cause localized heating and potential performance degradation. Follow manufacturer specifications.

Environmental Conditions

Indoor installation only. Ambient temperature range: -25°C to +50°C. Avoid corrosive gases, conductive dust, and excessive vibration. Water cooling ensures reliable operation in high-frequency, high-power applications.

Frequently Asked Questions

What is the recommended water flow rate and inlet temperature for the cooling circuit? +

Flow rate depends on the specific power rating and ambient conditions. For standard applications, a flow rate of 4-6 L/min per 100 kvar is typical, with inlet temperatures between 15°C and 35°C. Detailed cooling requirements are provided with each unit based on the operating parameters.

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 water cooling system improve capacitor performance? +

The built-in high-efficiency water cooling circulation system removes heat generated during the heating process in a timely and effective manner, maintaining the capacitor within the operating temperature range. This design extends service life, improves overall system stability, and ensures safe operation in high-frequency, high-power applications.

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. The water cooling system effectively manages thermal stress, contributing to extended service intervals, with regular monitoring of capacitance and dissipation factor recommended to track degradation.
