Wide on-load voltage regulation transformer
- Multi-position and wide voltage regulation: 9 voltage regulation positions; voltage regulating range: ±10% and ±20%.
- Primary and secondary fusion of transformer: The transformer not only realizes automatic voltage control, abut also expands the monitoring of operating condition (current, voltage, oil temperature and pressure, etc.) to realize the primary and secondary fusion.
- "Three-remote" function: support GPRS wireless communication and RS485 serial port communication, monitor the operating condition of transformer remotely, check and modify the parameters, and realize automation of distribution network area. Good man-machine interface: The controller is provided with a Chinese LCD screen and a built-in WIFI module so that the maintenance personnel can check the working condition of transformer through LCD screen or mobile phone APP without the need of outage and improve the maintenance efficiency.
- Miniaturized design, small volume and convenient installation: the on-load tap switch is of a combination structure to realize miniaturized design. The switch is installed horizontally without independent oil chamber, and the vacuum pipe is arc-extinguishing and simple in structure. The transformer is compact in volume and convenient to install.
- Free of maintenance and long in service life: oil filtration is unnecessary during operation, periodic maintenance is not needed, and the service life of tap switch is 50,000 times, and the mechanical service life is 100,000 times.
- Be applicable to the areas with large voltage fluctuation, such as the areas with large seasonal and daily load change and small hydropower generating areas.
