I. Product Overview

The three-phase load unbalance automatic adjustment device (referred to as the regulator) is a new generation of products developed by the company after summarizing various products developed by our company for many years, and drawing on various domestic and international technologies. Full, flexible installation, its controller full Chinese LCD menu, easy to operate.
It is mainly used for automatic adjustment of residential areas, rural power grids, etc. There is a large amount of single-phase load at the customer end, and the randomness of load access and the power consumption are not simultaneous, and the distribution transformer of the power supply point is in an asymmetrical operation state. Make the three-phase load as balanced as possible.

2. Features

1．Display function

1) The controller adopts Chinese liquid crystal display mode, which can display various operating parameters and setting parameters;
2) The controller adopts the touch button mode, which is beautiful and generous;
3) Digital ammeter to visually display the operating current of the device;

1) The setting of protection settings such as overvoltage protection value, overvoltage lockout value and undervoltage protection value;
2) setting of the switching limit value such as delay time, input, and cutting threshold;
3) Set the sampling current transformer ratio.

3．Measurement function

Distribution voltage, current, power factor, active power, reactive power measurement.
4. Control function
1) Automatic and manual control of the switching of the capacitor. In the automatic control, the switching is performed according to the controlled physical quantity - reactive power;
2) The capacitors with the same capacity work according to the principle of bad switching, and the capacitors with different capacities are coded and switched according to the reactive power shortage;
5. Protective function
Harmonic protection, overvoltage protection, overvoltage blocking, undervoltage protection, phase loss protection, and undercurrent protection of power distribution system.
6． Signal function

1) The signal of each capacitor is put into operation and returned, and the capacity signal of each capacitor is displayed;
2) Display of the power distribution parameter over-limit signal (overvoltage, undervoltage, undercurrent, etc.);
3) The controller itself or capacitor fault display.
