Product overview:
With the continuous improvement of people's living standards, the electricity load is also increasing rapidly. In rural power grids or distribution networks in mountainous areas, due to thin power supply lines and long power supply distances, voltage drops are too large, causing electrical appliances to fail to start, which has an impact on people's lives. It is urgent to solve the low voltage problem and improve the quality of the power grid. The intelligent low-voltage capacitor lifting device is suitable for end users who are far away from the distribution transformer, have large voltage drops, and have poor voltage quality. The low voltage within a certain range on the user side can be improved to a certain extent, the low voltage can be improved, and the reactive power can be effectively compensated to reduce line losses, so that the user's household appliances or production appliances can be used normally, and the power environment and voltage quality of residential users can be improved.

4. Working principle:
Utilizing the compensation characteristics and capacitance rise effect of the capacitor, the device monitors the electric energy data in real time. When the voltage at the end of the line is lower than the normal voltage and the power factor is low, the device starts and automatically adjusts the gear according to the power quality parameters on the load side for compensation, thereby compensating for reactive power and effectively reducing line losses. The device is installed in parallel close to the user's load. According to the different load characteristics of users and different line paths and losses, after installing this equipment, the user's voltage can be appropriately increased. Distributed installation is adopted to be as close to the end users as possible. This equipment uses a multi-level switching method when working to monitor the changes in electric energy indicators in real time. The number of switching groups is changed according to the changes in electric energy indicators after input. When the input is increased, the voltage increase is very small or does not increase, then the system The added group will be automatically exited, and the system will track and monitor the voltage data in real time. When the voltage returns to normal and stable, the equipment will gradually exit on its own. If the power indicator decreases again, the equipment will automatically be put into the corresponding group according to the fluctuation amplitude of the power. This can effectively improve the low voltage and prevent overcompensation or increased line loss caused by excessive input, and protect the quality of power consumption.
