3.0KV 700HZ Induction Heating Water Cooled Capacitor

3.0KV 700HZ induction heating water-cooled capacitor works stably at high frequencies up to 700 Hz to ensure energy transmission efficiency. Its optimized electrical performance enables it to quickly and evenly transfer energy to the heated object during the induction heating process, significantly improving heating efficiency and uniformity, shortening heating time, and reducing energy consumption. The specially designed water cooling system effectively solves the problem of capacitors easily heating up under high-frequency operation. The heat is taken away by circulating cooling water to keep the internal temperature of the capacitor stable, extend its service life, and reduce the risk of performance degradation or damage caused by overheating. Excellent performance stability can be maintained even under long-term, high-intensity working conditions. Widely used in metal smelting, heat treatment, welding, surface quenching, and other industrial fields, 3.0KV 700Hz induction heating water-cooled capacitors have become an ideal choice for users in many industries due to their performance and wide compatibility. Whether it is a large production line or a precision laboratory, it can be easily adapted to meet the heating needs in different scenarios.

Induction Heating & Melting Capacitors

3.0kV 700Hz Induction Heating Water Cooled Capacitor

Designed for high-frequency induction heating applications requiring efficient energy transmission and water-cooled thermal management. Supports metal smelting, heat treatment, welding, and surface quenching operations.

Product Overview

The RFM series delivers rated voltage of 3.0 kV at 700 Hz, supporting induction heating applications requiring efficient energy transmission and water-cooled thermal management.

The capacitor construction uses metallized polypropylene film dielectric with self-healing properties. Stable operation at frequencies up to 700 Hz ensures energy transmission efficiency. Optimized electrical performance enables rapid and uniform energy transfer during induction heating, significantly improving heating efficiency and uniformity while shortening heating time and reducing energy consumption. The specially designed water cooling system effectively solves the problem of capacitors heating up under high-frequency operation.

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

01

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.

02

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. Water cooling system keeps internal temperature stable.

04

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.

05

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 under high-frequency, high-intensity conditions.

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 specially designed water cooling system effectively removes heat through circulating cooling water, keeping the internal temperature of the capacitor stable. This extends service life, reduces the risk of performance degradation or damage caused by overheating, and maintains performance stability even under long-term, high-intensity working conditions.
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.
