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.

What tests are required for dry-type transformers?
1 Pre - commissioning InspectionAs a front - line tester, before formally commissioning a dry - type transformer, I need to carry out a comprehensive and systematic inspection. First, I conduct a visual inspection of the transformer body and its accessories, carefully checking for mechanical damage or deformation. Then, I check whether the leads of the high - and low - voltage windings are firmly connected and whether the bolt tightening torque meets the standard requirements (usually 40 - 60N&m

1 Pre - installation PreparationAs a front - line installer, I know very well that the preparation work before installing a dry - type transformer must be thorough. First, I will carefully review the design drawings and technical documents, and check one by one the technical parameters such as the model specification, rated capacity, and voltage level of the transformer to ensure they are in full compliance with the design requirements. Then, I will conduct an unpacking inspection of the transfo

What are the causes of dry-type transformers burning out during operation?
1 Fault PhenomenonI am engaged in front - line fault maintenance work, and recently encountered problems with dry - type transformers. Dry - type transformers have a simple structure, are convenient for transportation, and easy for maintenance. They are widely used in power distribution places with relatively high environmental protection requirements. Because of their good fire - resistance, they can be installed in load - center areas to reduce voltage loss and power loss.The property manageme

A Novel Detection Method for Stuck Faults in Load Switches
In recent years, as distribution automation advances, load switches see wider use in distribution lines. Yet, mechanical - failure - induced accidents are on the rise, burdening line operation and maintenance.Poor mechanical performance is the main cause of switch faults. Many scholars study large - scale switchgear operation, using methods like coil current detection, vibration signal analysis, switch travel testing, ultrasonic flaw detection, and infrared thermometry.
