Optimization Plan for Dust Prevention in Dust Environment of African Rural Lighting electrical ready board

Frequent sandstorms occur in rural Africa, and it is difficult to achieve long-term dust prevention solely by improving the protection level of the enclosure. Multiple optimizations need to be made based on the on-site working conditions, and specific measures are as follows.

In terms of box structure, a maze style inlet and outlet hole is used instead of a straight hole design, and a bent air duct is used to block sand and dust from entering directly; Install rubber sealing sleeves and dust-proof rubber rings at the cable entrances and exits, fill the gaps with weather resistant sealant, and seal small gaps. The box door is equipped with thickened dust-proof sealing strips and a buckle type compression structure to prevent dust leakage in the door seams caused by vibration.

In terms of internal protection, it is necessary to ensure heat dissipation and block sand and dust. The filter screen is made of wear-resistant material (PC material), which is convenient for regular disassembly and cleaning. Install simple transparent protective barriers on the outside of components such as circuit breakers and wiring terminals to reduce the direct accumulation of floating dust.

Installation and operation optimization, raising the installation height of the electrical Ready Board Box to the ground and keeping it away from dusty areas on the ground; Install a tilted rain and dust cover on the top of the box to prevent wind and sand from blowing in diagonally. The box shell made of PC material has a smooth surface that is not prone to dust accumulation and is resistant to wind and sand wear. At the same time, simplify the internal layout, reduce the concave convex structure, lower the sand and dust attachment points, and provide simple operation and maintenance guidelines to facilitate local personnel to regularly clean the filter and box volume dust.
