Feeder Transformer (Automatic Line Voltage Regulator)
The SVR series line automatic voltage regulator is essentially an autotransformer with continuously adjustable voltage. It automatically adjusts the on-load tap changer position based on line voltage conditions to alter the transformer's turns ratio, thereby maintaining the output voltage within a specific range. It is suitable for power supply lines characterized by long transmission distances, heavy loads, significant voltage fluctuations, or power quality that fails to meet operational standards. It can also be used by industrial and mining enterprises where voltage quality does not meet production requirements.
Product Details
The SVR series automatic line voltage regulator is essentially an autotransformer with continuously adjustable voltage output. It automatically adjusts the on-load tap changer position based on line voltage conditions to modify the transformer's turns ratio, thereby maintaining the output voltage within a specified range. It is suitable for power supply lines characterized by long transmission distances, heavy loads, significant voltage fluctuations, or power quality that fails to meet operational standards. It is also applicable to industrial and mining enterprises where voltage quality does not meet production requirements.
Product Features
Utilizes an autotransformer structure capable of automatic on-load voltage regulation within a ±20% range; features excellent control performance and communication capabilities, supporting the "four remotes" functions: remote measurement, remote signaling, remote adjustment, and remote control; employs advanced anti-interference measures to ensure reliable controller operation; includes high- and low-limit protection for tap positions to prevent the tap changer from jamming; features separate oil tanks for the on-load tap changer and the autotransformer body;
Compact size, high capacity, lightweight, and low losses; easy to install; offers significant energy-saving benefits; high reliability.
Structural Characteristics
The automatic line voltage regulator extends the power supply radius of substations, making it suitable for long-distance power transmission in rural grids; it measures line voltage internally; ensures that voltage across the entire line meets national standards after regulation, with user-definable high and low regulation limits; effectively reduces line losses and distribution transformer losses; allows for the regulator to be switched into or out of service without interrupting the power supply.
