Energy-saving implementation process:
According to the investigation of the electricity consumption of East China Institute of Technology, the selected measurement point is the load of the building's comprehensive electricity consumption. Through the analysis of the operating parameters of the actual power load, we found that some of the load voltages are high and the three-phase power consumption is unbalanced because of the special electricity environment in the school. This is because most of the school's load is single-phase power supply, so after the three-phase power supply reaches each floor, it will be divided into three-phase single-phase power supply according to the actual situation, and the opening amount of the school load is affected by the number of students' class hours and hours. The unbalanced three-phase current will also cause the power factor of the load to be low and there will be high reactive power waste, which will also increase the loss and service life of the transformer. The equipment in the building laboratory will generate harmonics during operation. Frequent start-up of the lamps will also generate a large amount of transient currents, which will result in poor quality of the power grid, which will affect the service life of the equipment and waste a lot of power.
In view of the problems existing in the electricity system of your organization, we use the Ulumin energy-saving device and the Liyuan filter device to improve the operation of the integrated electricity and achieve the dual purposes of optimizing equipment operation and saving electricity expenses. After the power-saving transformation, the power quality can be significantly improved, the equipment failure rate is reduced by more than 15%, and the energy-saving rate is over 12%.

LQ-LY Lei Qi Li source system power saving device
Liyuan energy-saving device is a high-performance energy-saving device that specifically suppresses harmonics in the power grid. Liyuan system power saving device is a filter device that dynamically compensates for higher harmonics. It is mainly used in non-linear load conditions in the power grid, such as frequency conversion speed regulation, intermediate frequency heating, metallurgical electrolysis, chemical electrolysis, and other power electronic equipment industries. Fields; transportation areas such as electrified railways, underground railways, and trolleybuses; broadcasting, postal services, communications, and IT industry areas that are sensitive to harmonic disturbances; and conference and exhibition centers and commercial buildings that require strict power quality.
It is an advanced mechatronics equipment that integrates modern power electronics and computer technology and is used in urban and rural power grids and electrical users to compensate for harmonics of power.
As a new type of filtering device, the Liyuan system power-saving device has the ability to compensate multiple harmonic currents in the same period, and can be timely and automatically tracked and controlled. It can not only effectively eliminate harmonics, but also dynamically compensate for reactive power and improve unbalanced three-phase. It is different from common passive filters, is not affected by the system operating mode, does not generate harmonic resonance, and adapts to the power system. strong ability.
