RAM 3000V High Pressure Water Cooling Heating Capacitor

Designed for high-end power electronics applications requiring high voltage and water-cooled thermal management. Supports power conversion, pulse power systems, new energy storage, and radar transmitter applications.

Product Overview

The RAM series delivers rated voltage of 3000 V with water-cooled thermal management, supporting high-end power electronics applications requiring reliability under demanding conditions.

The capacitor construction uses advanced ceramic dielectric and metallized electrode technology to ensure electrical performance and long-term stability at operating voltage of 3000 V. The unique water-cooled heat dissipation system effectively solves the heat dissipation problem under high power density, directly removing heat through circulating cooling water. This design maintains low-temperature operation even under continuous high-load conditions, reducing the negative impact of thermal stress on capacitor performance.

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. Modular design facilitates installation.

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. Passed verification for high temperature, high humidity, and strong electromagnetic interference environments. Avoid corrosive gases 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 does the water cooling system improve capacitor performance? +

The water-cooled heat dissipation system directly removes heat through circulating cooling water, solving the heat dissipation problem under high power density. This maintains low-temperature operation even under continuous high-load conditions, greatly improving working efficiency and service life while reducing the negative impact of thermal stress on capacitor performance.

What environmental conditions can this capacitor withstand? +

The capacitor has passed strict electrical safety tests and environmental adaptability verification, ensuring stable and reliable operation in harsh environments including high temperature, high humidity, and strong electromagnetic interference. This makes it suitable for demanding applications such as radar transmitters and pulse power systems.
