What is the Function of Structure Characteristics and Role of Arc Suppression Coil in Power Grid？

Arc suppression coils are vital protective devices in power systems, primarily used to suppress overvoltage caused by grounding faults, ensuring the safety and stability of electrical equipment. Their design and structural features play a crucial role in the power grid. Below, we delve into the structure characteristics of arc suppression coils and their specific functions in the grid.

1. Structure Characteristics of Arc Suppression Coils:

●Single-phase Design: The arc suppression coil adopts a single-phase iron core design, suitable for addressing single-phase grounding faults in power systems. Compared to three-phase reactors, its simpler structure efficiently meets specific grounding protection needs.

●Main and Metering Coils: In addition to the main coil, the arc suppression coil is equipped with a metering coil for recording its operation, rated at 100V and 10A. This design facilitates monitoring and measurement, ensuring reliable system operation.

●Inductive Characteristics: Arc suppression coils possess high inductive characteristics, providing necessary reactance in the circuit to suppress overvoltage generated during grounding faults, thereby safeguarding equipment and system integrity.

2. Role of Arc Suppression Coils in Power Grid:

●Suppressing Intermittent Arcs: The capacitance at the grounding point can lead to intermittent arcs and overvoltage phenomena. The arc suppression coil increases grounding current to offset capacitive current, quickly extinguishing intermittent arcs to protect system safety.

●Enhancing System Stability:By rapidly extinguishing intermittent arcs, the coil effectively reduces overvoltage in the system, enhancing stability during grounding faults and minimizing the risk of equipment damage.

●Protecting Weak Insulation Points:Overvoltage poses a threat to weak insulation parts in the power system. The arc suppression coil mitigates overvoltage, protecting these components from damage and ensuring grid reliability.

●Optimizing Fault Handling:During a grounding fault, the arc suppression coil responds swiftly to adjust current states, optimizing fault response time and preventing escalation, thus ensuring the safe operation of the power system.

Conclusion

In summary, arc suppression coils possess unique structural characteristics and play a significant protective role in power systems. By suppressing overvoltage and intermittent arcs, they ensure the safety and stability of electrical equipment, thereby enhancing overall grid reliability. Thus, arc suppression coils are indispensable in modern power systems, serving as a critical safeguard for electrical safety.
