Selection Tips For Photovoltaic Booster Transformers
09-03 2024 | By:
In the selection process of photovoltaic booster transformers, multiple factors need to be considered comprehensively to ensure that the selected equipment can meet the actual needs of the project and achieve efficient and stable operation. Here are some key selection tips:
1. Determine the power capacity and output voltage
Power capacity: First, the required power capacity should be determined based on the total installed capacity and expected power generation of the photovoltaic power station. The capacity of the photovoltaic booster transformer should be able to match the total output power of the photovoltaic panels, and take into account a certain amount of redundancy to cope with future expansion needs.
Output voltage: According to the access requirements of the power grid, select the appropriate output voltage level. Generally speaking, photovoltaic booster transformers will boost the low-voltage AC generated by photovoltaic panels to a voltage level suitable for grid transmission, such as 10KV.
2. Consider conversion efficiency and loss
Conversion efficiency: The conversion efficiency of the photovoltaic booster transformer directly affects the power generation efficiency of the entire photovoltaic power generation system. Therefore, when selecting, products with high conversion efficiency should be given priority to reduce energy loss and improve the overall performance of the system.
Loss control: In addition to conversion efficiency, attention should also be paid to the no-load loss and load loss of the equipment. These losses will directly affect the operating cost of the equipment and the economic benefits of the system.
3. Evaluate safety performance and reliability
Safety performance: 10KV photovoltaic booster station box transformer should have complete safety protection functions, such as overcurrent protection, overvoltage protection, short-circuit protection, etc., to ensure that the power supply can be quickly cut off when the power grid fails or the equipment is abnormal, protecting the safety of the system and equipment.
Reliability: The reliability of the equipment is the key to ensuring the long-term stable operation of the system. When selecting, attention should be paid to the manufacturing process, material selection and brand reputation of the equipment, and products that have been strictly tested and verified and have high reliability should be selected.
4. Consider environmental adaptability and maintenance convenience
Environmental adaptability: Photovoltaic booster box transformers are usually installed in outdoor environments and need to have good waterproof, dustproof, anti-corrosion and other properties to cope with harsh climatic conditions. Therefore, attention should be paid to the protection level and weather resistance of the equipment when selecting.
Maintenance convenience: The maintenance convenience of the equipment is also one of the factors to be considered when selecting. Products with reasonable structural design and easy maintenance should be selected to reduce the subsequent operation and maintenance costs and improve the maintainability of the system.
5. Refer to market price and cost performance
The price of photovoltaic booster box transformer varies depending on factors such as brand, model, and configuration. When selecting, the market price and cost performance factors should be comprehensively considered to select products with excellent performance, reasonable price and perfect after-sales service. At the same time, you can also strive for more favorable prices and better services by comparing and negotiating with multiple suppliers.
6. Consult professional opinions and field visits
During the selection process, you can consult the opinions of professional photovoltaic system designers or engineers to understand the latest technology and product trends in the industry. In addition, you can also conduct field visits to some photovoltaic power stations that have been in operation to understand the performance and maintenance of photovoltaic box-type substations in actual applications, providing a more intuitive basis for selection.
The selection of photovoltaic booster box transformers is a process that comprehensively considers multiple factors. By carefully evaluating factors such as power capacity, output voltage, conversion efficiency, safety performance, reliability, environmental adaptability, maintenance convenience, market price and cost performance, you can select the photovoltaic booster box transformer product that best suits the project needs.
