They are usually used in public places, industrial areas and outside buildings to provide electricity. Water immersion in outdoor distribution cabinets may cause the following consequences: 1. Circuit short circuit or leakage, causing power system failure; 2. Power equipment, wires, connectors and other parts immersed in water may be corroded and damaged, affecting their normal operation; 3. Flooded distribution cabinets may pose a risk of electric shock, increasing the risk of personnel contacting current; 4. The internal components and controllers of the distribution cabinet may not work properly after being damp, affecting the stability and reliability of the entire power system; 5. Severe flooding may cause the power system connected to the distribution cabinet to short circuit, thereby causing large-scale power outages. Therefore, outdoor distribution cabinets should be installed to prevent flooding, or alarm when flooded, so as to handle the flooded outdoor distribution cabinets in time.
