Importance, selection and maintenance of inverter room door lock in solar power plant
With the rapid development of China's new energy industry, as an important part of renewable energy, solar power generation technology has been gradually valued and widely used. In the solar power generation system, inverter is one of the key devices to convert the direct current generated by photovoltaic panels into alternating current, and its working stability is directly related to the normal operation and economic benefits of the whole power station system.
First, the function and importance of inverter room door lock
Because the inverter will generate a lot of heat during operation, and its internal structure is complex and the lines are dense, it is usually necessary to set up a separate closed space for installation and management to ensure its good heat dissipation performance. At the same time, it can also avoid the damage to the equipment caused by external factors or the safety problems caused by misoperation. As the only access to the area, the "gate"-the door lock, bears the heavy responsibility of guarding.
Second, choose the appropriate door lock standard
1. Protection level: According to IEC62271200' s regulations on the protection requirements of high-voltage switchgear, the mechanical locks used in the inverter room should meet the IP4X/IP5X dustproof and waterproof standards;
2. Material technology: Considering the harsh environment (high temperature/high humidity, etc.), it is recommended to use stainless steel material, and the surface is specially treated to enhance the corrosion resistance;
3. Convenience and safety of operation: For those who need to go in and out for maintenance frequently, "difficult unlocking" will not only waste time, but also lead to problems such as failure in emergency. Therefore, it is recommended to use an integrated intelligent electronic lock scheme with numeric keyboard or card reading function, which is convenient, safe and reliable.
Iii. Matters needing attention in daily inspection and maintenance:
Regularly carry out patrol activities to find out the problems in time, such as: observing whether there are foreign objects stuck in the keyhole, which makes it difficult to open it; Confirm whether the sealing strip of the door crack is intact to prevent short circuit failure caused by rainwater infiltration, etc. In addition, special attention should be paid to keep it clean and dry to avoid rust and aging affecting its service life.
IV. Conclusion
To sum up, when building a modern intelligent operation and maintenance management system, we must attach great importance to every detail, especially the seemingly insignificant but vital place like the door lock. Only through scientific and reasonable selection of high-quality products and professional and meticulous maintenance can we effectively improve the overall management level, reduce operating costs and extend the service life of equipment so as to achieve the goal of sustainable development!
