Product description
FSVR line automatic voltage regulator is a device that tracks the line voltage change and automatically adjusts the transformation ratio of the device to ensure the stable output voltage. The input voltage can be automatically adjusted in the range of -20% to +10%. It is especially suitable for lines with large voltage fluctuations or lines with large voltage drops. This feeder voltage regulator is installed in series at 6kV, 10kV, In the middle and rear part of the 35kV line, the line voltage is adjusted within a certain range to ensure the user's power supply voltage and reduce the line loss of the line. In addition, the FSVR feeder automatic voltage regulator is also suitable for substations where the main transformer does not have the ability to adjust voltage. Install this type of voltage regulator on the outlet side of the substation transformer to ensure the bus voltage on the outlet side. It is widely used in the national rural power grid, urban power grid, oil field, coal, chemical industry, substation and other fields.
Feature

Automatically adjust the three-phase on-load tap switch gear position by tracking the voltage change, with reliable action and high voltage adjustment accuracy;
The voltage reference, action delay, allowable range, limit of times can be adjusted according to needs, and the parameter setting is flexible and convenient;
Display the number of FSVR on-load tap-changer gear actions and the current gear position, with the highest and lowest gear indications;
With the upper limit and lower limit protection of the gear position, the action time limit function, which effectively improves the reliability of the product;
The controller has over-voltage rapid drop and under-voltage protection functions. When the line is in an over-voltage or under-voltage state, the controller automatically locks; to ensure the safe operation of the on-load tap changer
The controller adopts industrial-grade control chip, which has high reliability and strong anti-interference ability, which can adapt to the harsh outdoor environment;
With RS485 communication interface, the parameters of the controller can be viewed and modified within 30m from the installation point through the wireless communication module.
