Description

Description

As a pioneer and the first source factory in China's voltage regulator industry, we have been deeply rooted in the sector for decades, accumulating profound technical expertise. Leveraging top-tier R&D capabilities and a mature manufacturing system, our products have gained widespread market trust with reliability and performance that far exceed industry standards.

The 24kV single-phase pole-mounted 32-step automatic voltage regulator, based on advanced on-load voltage regulation technology, enables precise 32-step voltage adjustment. Equipped with an intelligent monitoring module, it can capture subtle voltage fluctuations in the distribution network in real time, respond quickly, and automatically switch voltage regulation taps to adapt to complex and changeable distribution network conditions.

Designed for pole mounting, it is compatible with different pole types and installation environments, eliminating the need for additional complex foundations and greatly simplifying the deployment process. With fully automated operation—from voltage detection and tap switching to voltage regulation execution—no manual intervention is required, which not only improves operation and maintenance efficiency but also avoids human operation errors.

It stably outputs 24kV single-phase voltage, effectively suppressing voltage deviations, flicker, and other issues, providing continuous and reliable power support for end devices and user loads in the distribution network. This helps the distribution network achieve more efficient and reliable power distribution and operation in scenarios such as urban-rural power supply and small commercial-industrial power supply, contributing to the construction of an intelligent and stable power distribution and consumption ecosystem.

Product Features

Precision Voltage Regulation

  • 32-step voltage adjustment (±10% range, ~0.625% per step) for smooth and accurate voltage control.

  • Suitable for single-phase power distribution systems (2400V to 34,500V, 50/60Hz).

Robust Construction

  • Oil-immersed auto-transformer design ensures durability and efficient heat dissipation.

  • High-creep porcelain bushings and MOV-type arresters provide superior insulation and surge protection.

Smart Control & Monitoring

  • RVR intelligent controller with GPRS/GSM/Bluetooth for remote monitoring and adjustments.

  • Real-time voltage & current sampling via built-in sensors (CT/PT inputs).

Key Advantages

  • High Reliability: Oil-immersed construction and conformally coated PCBs ensure long-term stability in harsh environments.

  • Wide Compatibility: Supports 60Hz & 50Hz systems with voltage ratings up to 34.5kV (200 kV BIL).

  • Automated & Remote-Controlled: Smart controller enables real-time adjustments via mobile or SCADA systems.

  • Enhanced Safety: Built-in fault protection and pressure/oil monitoring prevent catastrophic failures.

  • Low Maintenance: Modular design simplifies servicing (e.g., tap changer motor, replaceable bushings).

Technical Specifications

Some of the voltage ratings include 50Hz (6kV, 6.35kV, 11kV, 15kV, 22kV, 33kV) and 60Hz (7.62kV, 13.8kV, 14.4kV, 19.92kV, 34.5kV). Customization is available.

FAQ
Q: Will this voltage regulator cause an impact on the power grid during voltage regulation?
A:

No. Adopting a design of step voltage regulation + induction regulation, it realizes smooth voltage switching. Combined with the buffering characteristics of oil-immersed insulation, it can avoid voltage surges that may impact the power grid and downstream equipment, making it suitable for scenarios requiring high power supply stability.

Q: What are the key points for the daily maintenance of the oil-immersed self-cooled induction voltage regulator (6kV~33kV)?
A:

It mainly requires regular inspection of the insulation oil level and quality (at least once a year), cleaning dust on the radiator surface to ensure heat dissipation efficiency, and monitoring the operation status of the tap changer. These maintenance measures can guarantee the long-term stable operation of the equipment, and professional power operation and maintenance personnel are recommended for the operations.
