The long-distance power supply and stability guarantee of lighting electrical ready boards in remote rural areas are key to improving the quality of rural power supply. Due to geographical limitations, these areas often face problems such as long power supply distances, high voltage losses, and poor stability, requiring comprehensive measures from three aspects: technology, equipment, and management.

On a technical level, it is necessary to optimize the power supply plan. Traditional low-voltage power supply suffers from severe voltage attenuation due to line resistance, and can use boost buck technology, such as raising the 220V voltage to 660V or 1100V for transmission, and then reducing it to 220V at the end, which can significantly reduce line losses. For example, a certain project reduced the power loss of a 1.3-kilometer line from 5 kilowatts to 196 watts and voltage loss from 144V to 28V through boost technology, significantly improving power supply stability. In addition, the combination of distributed power generation and energy storage technology, such as solar energy+battery packs, can solve the problem of insufficient terminal voltage and provide emergency backup power.

At the equipment level, suitable products need to be selected. The electrical ready board should be made of waterproof, dustproof, and corrosion-resistant PC engineering plastic box. The internal circuits should be arranged according to functional zones, with strong and weak electricity separated, and equipped with a final residual current action protector to achieve "one household, one protection". For long-distance power supply, low resistance cables such as 2.5mm ² and above wire diameter should be selected, or front-end voltage stabilization circuits should be used to stabilize the input voltage within the required range of the equipment and reduce the impact of voltage drop.

At the management level, it is necessary to strengthen maintenance and monitoring. Establish a regular inspection system, focusing on checking issues such as rusting of electrical ready boards, aging of circuits, and poor grounding, and promptly replacing damaged components. At the same time, an intelligent monitoring system is introduced to monitor parameters such as voltage, current, and temperature in real time. In case of abnormalities, an automatic alarm is triggered and the power is cut off to prevent accidents from escalating. In addition, strengthen user safety education on electricity use, standardize electricity usage behavior, and reduce human induced malfunctions.
