Implement The Five Principles Of Power Distribution Cabinets To Establish A Power Equipment Distribution System.

This principle requires that each load device be managed by a dedicated circuit breaker unit, and that each branch protection device be equipped with a single leakage protection component, independent cabinet, and additional locks, which helps to standardize switch control behavior in actual power distribution systems.

In the implementation phase, the power supply equipment within each Powbinet unit should correspond to the switchgear; a single switch should not serve multiple loads simultaneously. This design concept is reflected in the layout of the distribution cabinets on-site, reflecting industry practice to prevent switchgear from carrying excessive power loads.

For secondary and tertiary power distribution systems, distribution cabinets often serve as distribution nodes, and their internal structure achieves a hierarchical division from the main incoming line to specific circuits. Each branch circuit, after passing through the circuit breaker unit and leakage protection device, extends to the downstream electrical equipment; the systematic wiring and labelling standards are inherently consistent with this principle.
