Solar transformer series Solar transformer W/Wα
Fuji Electrode Industry Co., Ltd.
About This Product
The solar transformer's "α function" and "sharing" structure make it possible to save space, reduce costs, and shorten the construction period for the entire solar power generation facility.
A step-up transformer that needed to be installed one-to-one with a power conditioner. One Soratra W performs the functions of two step-up transformers. Soratra Wα has added excitation inrush current suppression function to Soratra W. Use this one unit for a 1MW configuration of two 500kW output power conditioners.
Features
■Solar transformer α function
Countermeasures against instantaneous voltage drops that need to be taken into account when connecting power generation equipment to the grid. Since the solar transformer α suppresses the magnetizing inrush current that causes this, it becomes possible to take measures against instantaneous voltage drops with the transformer, eliminating the need for a separate device to suppress the magnetizing inrush current.
■What is instantaneous voltage fluctuation countermeasure?
If the voltage drop due to magnetizing inrush current has a large impact on the grid and exceeds the allowable value specified in the grid interconnection regulations, suppression of the magnetizing inrush current will be required during grid interconnection negotiations. In some cases, the generated magnetizing inrush current is suppressed by attached equipment, but the Soratra α has a structure in which the transformer itself suppresses the magnetizing inrush current.
■Sharing type
Sharing multiple functions on one device. Consolidates up to 3 transformers into one. Space-saving of the entire solar power generation equipment - Wiring can be omitted.
■Highly efficient transformers to increase power generation efficiency
The solar transformer series complies with the "Top Runner Transformer Secondary Judgment Standards", the energy consumption efficiency standard stipulated by the Energy Saving Act. High energy conversion efficiency improves the profitability of power generation businesses. Additionally, if you simultaneously adopt DAIHEN's highly efficient "air conditioner-less" power conditioner, you can further improve your profits.
