OSZ-10kV Line Automatic Voltage Regulator

The OSZ-10kV line automatic voltage regulator is an intelligent voltage stabilization device specifically designed for medium-voltage distribution networks (typically at 10kV or 35kV levels). It is usually installed in the middle or at the end of distribution lines with long supply distances and large load fluctuations. Its core mission is to automatically stabilize the voltage, completely resolving issues such as the failure of user-side appliances to start properly or reduced efficiency due to "low voltage," and shortened equipment lifespan caused by "high voltage."

• No manual intervention is required; it automatically detects voltage fluctuations and regulates voltage, significantly reducing operation and maintenance pressure.
• On-Load Voltage Regulation: The voltage regulation process does not cause any impact on the power grid, is imperceptible to users, and ensures high power supply reliability.
• Typically has a wide voltage regulation range (e.g., ±10% or ±20%), capable of handling severe voltage fluctuations.
• Three-Phase Independent Regulation (Optional): Advanced models support phase-by-phase voltage regulation, effectively addressing the common issue of three-phase load imbalance in rural power grids, which is one of its significant advantages.
• Equipped with standard communication interfaces (e.g., GPRS/4G, fiber optic Ethernet, etc.), can be integrated into distribution automation systems for remote data monitoring, parameter settings, fault alarms, and data analysis.
• Includes overcurrent, overvoltage, undervoltage, phase loss, gas (for oil-immersed types), and other protection functions to ensure the safety of the equipment and the power grid.

• Addressing the persistent problem of 'low voltage' caused by long supply distances and low end-of-line loads.
• Complex terrain and high line impedance result in significant voltage losses.
• Internal distribution networks experience large load fluctuations, requiring stable voltage.
• Such as wind farms and photovoltaic power station outlets, to smooth the impact of renewable energy fluctuations on grid voltage.

  The OSZ line automatic voltage regulator is an intelligent power device installed on long-distance power supply lines. It can automatically monitor and adjust voltage, stabilizing the line voltage in real-time through on-load tap-changing technology. It effectively addresses low or high voltage issues at the end of the power grid caused by long distances or load fluctuations, significantly improving power quality and supply reliability.
