How can photovoltaic boost box substation ensure safe operation in outdoor extreme environments?

Publish Time: 2025-04-05

Under the general trend of clean energy development, photovoltaic power stations are important energy facilities, and the safe operation of their core equipment, photovoltaic boost box substation, is crucial. However, outdoor extreme environments, such as strong winds, heavy rains, high temperatures, low temperatures, etc., bring many challenges to the safe operation of photovoltaic boost box substations. In order to ensure its stable operation in extreme environments, a series of comprehensive protection measures need to be taken.

Structural stability and protection design

The structural stability of photovoltaic boost box substation is the basis for resisting extreme environments. During the design phase, the local climate characteristics and geological conditions should be fully considered to ensure a stable foundation to prevent the substation from tilting or collapsing due to unstable foundations. For example, in areas with strong winds, wind-resistant supports should be added to make the substation structural design strong and able to withstand strong winds. At the same time, a sealing design is adopted, and waterproof rubber rings, drainage grooves, etc. are set to prevent rainwater from entering. The box body adopts a solid metal shell with a high level of protection, which can block collisions with foreign objects and prevent people from accidentally contacting live parts. In heavy rain, the impact of rain on the substation can be reduced by building waterproof dams, drainage ditches and other facilities, and paying attention to weather forecasts in real time, making drainage emergency plans in advance, and adding temporary drainage facilities before the heavy rain to ensure the smoothness of the drainage system.

Electrical protection and equipment maintenance

The photovoltaic boost box substation is equipped with multiple electrical protections, such as overcurrent, short circuit, and leakage protection devices. When abnormal, the circuit is quickly cut off to protect the safety of equipment and personnel. Regularly maintain and maintain electrical components, check key electrical components such as circuit breakers to ensure that they are flexible in operation and have good contact, and replace aging or damaged components in time to maintain stable equipment performance. For example, regularly check the status of each electrical equipment and insulation sealing of the photovoltaic power station. If the sealing status is poor, it must be handled in time. For key electrical nodes, such as DC wiring and AC wiring, they must be checked in detail, and if there are sealing and wiring problems, they need to be handled immediately.

Lightning protection grounding and fire prevention measures

Lightning and fire are important factors threatening the safety of photovoltaic boost box substation. To prevent lightning strikes, a lightning protection grounding system should be installed to lead lightning into the ground. Regularly measure whether the grounding resistance value of the grounding device meets the design requirements, and regularly check whether the connection between each equipment component and the grounding system is reliable. If the connection is not reliable, it must be welded firmly. After the thunderstorm or before the thunderstorm season arrives, check whether the square array junction box and the lightning protection device installed in each device are invalid, and replace them in time as needed. At the same time, equip with complete fire prevention facilities, such as fireproof partitions and fire extinguishing devices, to reduce the risk of fire.

Intelligent monitoring and personnel training

The intelligent monitoring system can monitor the operating parameters of the equipment in real time, and alarm in time when abnormalities are found, to ensure the safe and stable operation of the substation in all aspects. Through intelligent monitoring, operation and maintenance personnel can understand the operating status of the equipment in a timely manner, discover potential problems in advance and take measures. In addition, strengthen the training and management of operation and maintenance personnel to improve their professional skills and safety awareness. Formulate strict installation operation procedures and safety measures, strengthen construction site management, and ensure the safety and controllability of the installation process. Carry out special management for high-risk operations such as high-altitude operations and electrical operations to ensure that operators receive professional training and wear safety protection equipment.

In extreme outdoor environments, ensuring the safe operation of photovoltaic boost box substations requires multiple aspects including structural design, electrical protection, lightning and fire protection, intelligent monitoring, and personnel training.
