RAM 3000KVar Middle Frequency Water Cooled Capacitor

Designed for high-demand medium-frequency induction heating, smelting, and high-power inverter systems. Supports reactive power compensation, harmonic reduction, and energy storage with water-cooled thermal management.

Product Overview

The RAM series delivers reactive power capacity of 3000 kvar with water-cooled thermal management, supporting medium-frequency induction heating and high-power inverter applications requiring stability and reliability.

The capacitor construction uses metallized polypropylene film dielectric with self-healing properties. The design incorporates advanced water-cooling heat dissipation technology that effectively addresses performance degradation and shortened service life caused by high temperatures under traditional air cooling, ensuring stability and reliability under high-intensity and long-term operation. The 3000 kvar ultra-large capacity design provides sufficient energy support to meet the stringent requirements of large industrial equipment for power quality and stability.

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.

Protection & Monitoring Setup

Verify self-protection and fault warning systems are properly configured during installation. Test safety mechanisms and monitoring functions before energizing the system.

Environmental Conditions

Indoor installation only. Ambient temperature range: -25°C to +50°C. Avoid corrosive gases, conductive dust, and excessive vibration.

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 do the self-protection and fault warning functions work? +

The capacitor features built-in multiple safety mechanisms that monitor operating status in real-time. Upon detection of abnormalities such as overvoltage or overcurrent, the protection system initiates immediate response, effectively preventing potential risks and ensuring equipment safety and production continuity.

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-cooled design and self-protection features contribute to extended service intervals, with regular monitoring of capacitance and dissipation factor recommended to track degradation.
