Product Detail

Description

The RVR-1 is a single-phase, oil-immersed automatic voltage regulator based on an autotransformer design. It is equipped with an advanced RVR controller that continuously samples voltage and current signals from the distribution line. Through an integrated on-load tap changer (OLTC), the RVR-1 dynamically adjusts voltage levels to match load conditions, improving voltage stability and system efficiency.

The system combines a tap-changing transformer, motor-driven switching mechanism, and intelligent control to provide automatic voltage regulation with high precision and reliability.

Key Features

  • Wide Regulation Range:Regulates voltage from -10% (buck) to +10% (boost) in 32 fine steps, approximately 0.625% per step.

  • Smart Control System:Features a self-developed RVR controller with support for GPRS/GSM and Bluetooth communication, enabling real-time data acquisition and remote control.

  • Advanced Protection Functions:Integrated lock-out protection against line faults, overloads, overcurrent, and undervoltage conditions.

  • Customizable Settings:Supports adjustable voltage reference values, tap step limits, tap delay time, and user-defined control parameters.

Cost Differences and Performance Comparison of 35kV New Energy Transformers Based on Dry-Type, Mineral Oil, and Vegetable Oil
Cost Differences and Performance Comparison of 35kV New Energy Transformers Based on Dry-Type, Mineral Oil, and Vegetable Oil
For users, when purchasing a 35kV new energy transformer, choosing between dry-type, mineral oil-filled, or vegetable oil-filled types involves multiple considerations. These include user habits, maintenance-free performance, safety and fire resistance, volume and weight, among others. However, cost differences are undoubtedly one of the most crucial factors.To illustrate the issue intuitively, this paper selects a three-level energy efficiency dual-winding new energy transformer with a rated ca

What is the connection group of a transformer?
What is the connection group of a transformer?
Transformer Connection GroupThe connection group of a transformer refers to the phase difference between the primary and secondary voltages or currents. It is determined by the winding directions of the primary and secondary coils, the labeling of their start and end terminals, and the connection mode. Expressed in a clock-like format, there are 12 groups in total, numbered from 0 to 11.The DC method is commonly used to measure the transformer's connection group, mainly to verify whether the con

Working Voltage in Power System
Working VoltageThe term "working voltage" refers to the maximum voltage that a device can withstand without sustaining damage or burning out, while ensuring the reliability, safety, and proper operation of both the device and associated circuits.For long-distance power transmission, the use of high voltage is advantageous. In AC systems, maintaining a load power factor as close to unity as possible is also economically necessary. Practically, heavy currents are more challenging to handle than hi

What is Steady State Stability in Power System?
Definition of Steady State StabilitySteady state stability is defined as the capability of an electric power system to sustain its initial operating condition following a small disturbance, or to converge to a state closely approximating the initial condition when the disturbance persists. This concept holds critical significance in power system planning and design, the development of specialized automatic control devices, the commissioning of new system components, and the adjustment of operati

What is the sequence for powering down the transformer?
What is the sequence for powering down the transformer?
The sequence for shutting down a main transformer is as follows: when de-energizing, the load side should be shut down first, followed by the power supply side. For energizing operations, the reverse order applies: the power supply side is energized first, then the load side. This is because: Energizing from the power supply side to the load side makes it easier to identify the fault range and take prompt judgment and handling measures in case of a fault, preventing the fault from spreading or e

What are the methods for switching operations of station transformers?
What are the methods for switching operations of station transformers?
Let's take an auxiliary power system with two station transformers as an example. When one station transformer needs to be out of service, there are two operation methods: non-interruptive power supply and instantaneous power interruption. Generally, the method of instantaneous power interruption on the low-voltage side is preferred.The operation method for instantaneous power interruption on the low-voltage side is as follows:Open the 380V power incoming circuit breaker of the corresponding sec
