Operating Mechanism And Practical Application Of Power Distribution Cabinet
The main control components within the Powbinet control cabinet include circuit breakers and disconnectors. Circuit breakers utilize various arc-extinguishing media, including oil, sulfur hexafluoride (SF6), vacuum, and air, during circuit breaking and connection. These media rapidly extinguish the arc, protecting the contacts and reliably disconnecting the circuit. Disconnectors feature clearly marked break points, clearly indicating whether the circuit is on or off. They are primarily used to isolate power supplies under no-load conditions, providing safety assurance for line and equipment maintenance.
The control cabinet's panel design considers the needs of the actual operating environment. All components are neatly and evenly arranged, allowing operators to perform closing and opening operations using simple mechanical means without complex auxiliary operations. This intuitive design enables staff to quickly respond to system needs and rapidly switch circuits during faults or maintenance.
The control cabinet integrates multiple protection mechanisms, including overload protection, short-circuit protection, and ground fault protection. When the system detects an anomaly (such as overload, short circuit, or fault), the relevant protection devices automatically trigger, causing the circuit breaker to automatically disconnect without manual intervention, preventing circuit damage. Meanwhile, the manual operating mechanism allows staff to perform active circuit control as needed.
