Product Description

 

ST-SVR Lline Voltage Regulator 

Product Introduction

ST-SVR line voltage regulator is a device that keeps track of line voltage changes and automatically adjusts the transformation ratio of the device itself to ensure stable output voltage.
The input voltage can be automatically adjusted within the range of ±20%. It is especially suitable for lines with large voltage fluctuations or lines with large voltage drops. This feeder voltage regulator is installed in series in 6kV, 10kV, and 35kV lines. In the rear part, 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 ST-SVR 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 transformer substation to ensure the bus voltage on the outlet side. It has a wide range of applications in the national rural power grid, urban power grid, oil field, coal, chemical industry, substation and other fields.

Main Feature
(1) The whole device has large capacity, low loss, small size, and easy installation and maintenance;
(2) Automatically adjust the three-phase on-load tap switch gear position by tracking the voltage change, which has reliable action and high voltage adjustment accuracy;
(3) The voltage reference, the action delay, the allowable range, and the limit of the number of times can be adjusted according to the needs, and the parameter setting is flexible and convenient;
(4) Display ST-SVR on-load tap-changer gear action times and current gear position, with indications of the highest and lowest gears;
(5) 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;
(6) 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
(7) The controller adopts industrial-grade control chip, which has high reliability and strong anti-interference ability, which can adapt to the harsh outdoor environment;
(8) 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.
