High Voltage Line Regulator Transformer

     general1.FSVR online feeder automatic voltage regulating transformer (short for feeder automatic voltage regulator) is a device to ensure the stability of output voltage by tracking the line voltage change and automatically adjusting the body ratio of the device.Can be in the range of plus or minus 20% to automatically adjust the input voltage, it is especially suitable for large voltage fluctuation of the circuit or pressure drop large circuit, the feeder series voltage regulator is installed in 6 kv, 10 kv, 35 kv lines in the back, in a certain range of line voltage adjustment, ensure the user's power supply voltage stability, reduce the line loss line.In addition, the FSVR feeder automatic voltage regulator is also suitable for the substation where the main transformer does not have the voltage regulation ability. This voltage regulator is installed on the transformer outlet side of the substation to ensure the outlet side bus voltage.In the national agricultural network, urban network, oil field, coal, chemical industry, substation and other fields have a wide range of applications.Two, main characteristics(1) Large capacity, low loss, small volume, easy to install and maintain;(2) Automatically adjust the gear of three-phase on-load tap switch to track voltage change, with reliable operation and high voltage adjustment accuracy;(3) The voltage reference, action delay, allowable range and limit of times can be adjusted according to needs, with flexible and convenient parameter setting;(4) Display FSVR on-load tap switch gear number of actions and current gear, with high-grade and low-grade indication;(5) It has the functions of upper and lower gear protection and action time limit, which effectively improves the reliability of the product;(6) The controller has the functions of over-voltage drop and under-voltage protection. When the circuit is in the state of over-voltage and under-voltage, the controller automatically shuts down;Ensure the safe operation of on-load tap switches;(7) The controller adopts industrial-grade control chip, with high reliability and strong anti-interference ability, and can adapt to the harsh outdoor environment;(8) With RS485 communication interface, the controller parameters can be viewed and modified within 30m from the installation point through the wireless communication module.(9) It can be customized to realize remote operation control through SIM card or wireless network;Iii.
