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 RVR-1 stands as a single-phase oil-immersed automatic voltage regulator engineered with an autotransformer configuration at its core. Outfitted with a state-of-the-art RVR control unit, it constantly captures real-time voltage and current feedback from the power distribution network. Leveraging a built-in on-load tap changer (OLTC), the regulator dynamically fine-tunes voltage output to align with fluctuating load requirements—effectively enhancing grid voltage stability while optimizing overall system operational efficiency.

This integrated solution merges three key components: a tap-adjustable transformer, a motorized switching mechanism, and an intelligent control system. Together, they deliver high-precision automatic voltage regulation with exceptional reliability, ensuring consistent performance even in dynamic power distribution scenarios.

Key Features

Broad Voltage Regulation Range: Offers precise voltage adjustment spanning from -10% (buck mode) to +10% (boost mode), divided into 32 fine-tuning steps with a granularity of approximately 0.625% per step. This wide range ensures flexible adaptation to diverse grid voltage fluctuations and load demands.
Intelligent Control System: Equipped with a proprietary RVR controller, the regulator supports GPRS/GSM and Bluetooth communication protocols. This enables seamless real-time data collection (e.g., voltage, current, operating status) and remote operation capabilities, facilitating efficient monitoring and management of the device.
Comprehensive Protection Mechanisms: Integrates multi-layer protection functions to safeguard the regulator and connected equipment, including lock-out protection for line faults, overload protection, overcurrent protection, and undervoltage protection. These mechanisms effectively prevent damage caused by abnormal operating conditions, enhancing system reliability.
Highly Customizable Parameters: Allows users to flexibly adjust key settings according to specific application requirements, such as voltage reference values, tap step limits, tap switching delay time, and other user-defined control parameters. This customization capability ensures optimal performance in various power distribution scenarios.

Why Must a Transformer Core Be Grounded at Only One Point? Isn't Multi-Point Grounding More Reliable?

Why Does the Transformer Core Need to Be Grounded?During operation, the transformer core, along with the metal structures, parts, and components that fix the core and windings, are all situated in a strong electric field. Under the influence of this electric field, they acquire a relatively high potential with respect to ground. If the core is not grounded, a potential difference will exist between the core and the grounded clamping structures and tank, which may lead to intermittent discharge.I
