Wenlida Power Electronics Energy Storage Elevator Power Saver is a device that realizes elevator energy saving by using bidirectional high-power DC/DC technology and supercapacitor energy storage. The specific introduction is as follows:
-
Working Principle: The power saver includes an energy storage power saver system and an elevator frequency conversion controller system. The energy storage power saver system is composed of a DC/DC bidirectional converter module and an energy storage module. When the elevator is in power generation operation, the DC/DC bidirectional converter module charges the energy storage module with the voltage of the DC bus to store electrical energy; when the elevator is in energy-consuming operation, the DC/DC bidirectional converter module sends the electrical energy stored in the energy storage module directly back to the DC bus terminal of the frequency conversion controller of the elevator traction machine, so as to achieve the purpose of energy saving.
-
Product Advantages:
-
Efficient Energy Saving: It can store and reuse the energy originally consumed by the braking resistor, with a comprehensive power saving rate of up to 35% and a maximum power saving rate of 46.2%, which can effectively reduce elevator energy consumption.
-
Safety and Reliability: Appraised by the National Elevator Testing Center, destructive tests of short circuit and open circuit on the power saver, whether the elevator is running or stationary, will not affect the normal operation of the elevator. At the same time, when the power is suddenly cut off, it can act as an emergency power supply to make the elevator emergency leveling, ensuring the safe escape of personnel.
-
Avoiding Harmonic Interference: The power saver absorbs electrical energy from the DC terminal and stores energy at the DC terminal, avoiding the risk of AC harmonics interfering with the elevator, and there is no need to go through network access procedures or worry about threats to grid safety.
-
Long Service Life: It uses supercapacitors for energy storage, which can be charged and discharged frequently, with a service life of more than 10 years.
-
Application Cases: The power saver has been applied in places such as the Shanghai Chinese Academy of Sciences, hotels, and guesthouses, all achieving a power saving rate of more than 30% with safe and stable operation. In addition, Changsha City, Hunan Province has listed it as a provincial-level project for promotion, and Qingdao City, Shandong Province also has corresponding subsidy plans.
