On-load regulating capacity and voltage transformer
- Regulate voltage automatically and improve the voltage quality: detect the line voltage in real time, and control the tap switch to realize automatic voltage control of transformer according to the preset logic and algorithm and the line voltage fluctuation.
- Regulate capacity automatically, save energy and reduce consumption: detect the line current in real time, identify whether the transformer works in light load or heavy load automatically, and complete the capacity adjustment of transformer within 40ms according to preset logic and algorithm; reduce the no-load loss greatly in small capacity gear, and achieve the purpose of energy saving and consumption reduction.
- "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 distribution area with low voltage qualified rate and long proportion in no/light-load period.
