High-protection heat dissipation enhanced integrated distribution box

Abstract

This invention discloses a high-protection, heat-dissipating enhanced integrated distribution box, belonging to the field of power distribution equipment technology. The box is internally divided into five compartments: metering, intelligent terminal, incoming lines, outgoing lines, and reactive power compensation. The box uses double-layer side panels to form vertical heat dissipation channels, and the bottom plate has protective ventilation holes throughout. The top cover has a 5° raised inner lining plate to guide and exhaust hot air. The compartment partitions have simulated optimized heat dissipation holes, and high-power components are staggered to reduce thermal coupling. The reactive power compensation compartment is equipped with SVG and pluggable intelligent capacitors, and the temperature-controlled fan and built-in overheat protection provide dual protection. It is equipped with an emergency power interface with anti-reverse power transmission capabilities and features an intelligent distribution transformer terminal for 5G remote operation and maintenance. This invention constructs a complete internal convection heat dissipation system, significantly reducing equipment temperature rise while ensuring IP44 high protection. The modular design reduces production costs, and it has intelligent reactive power management, emergency power supply, and remote operation and maintenance functions, making it suitable for outdoor transformer substations.
