❓ Frequently Asked Questions
Q
What is the advantage of a semi-insulated design in this switchgear?
The semi-insulated design encases busbars and high-voltage live components in insulating materials, which effectively reduces phase-to-phase and ground clearance distances. This results in a more compact cabinet structure while maintaining high levels of electrical safety and reliability.
Q
What switch unit options are available for this product?
The core switch unit can be flexibly configured with three options: a load switch, a load switch-fuse combination, or a vacuum circuit breaker. This flexibility allows the product to be adapted to a wide range of application scenarios and operational requirements.
Q
What does the "five-prevention" interlock function mean?
The "five-prevention" interlock refers to a set of safety mechanisms designed to prevent five types of common electrical misoperations, such as operating a switch under load without proper sequencing, or incorrectly grounding live equipment. These interlocks are essential for ensuring safe and standardized operation of the switchgear.
Q
What is the rated current switching capacity of this switchgear?
The standard configuration of this product supports a rated current switching capacity of 630A, along with transfer current closing capability. This makes it suitable for medium-voltage power distribution systems requiring reliable and efficient current management.
Q
What is the short-circuit withstand current rating, and why does it matter?
This product has a short-circuit withstand current rating of 20kA for 3 seconds. This rating indicates the equipment's ability to endure high fault currents without sustaining damage, which is critical for protecting both the switchgear and the broader power distribution network during fault conditions.
Q
Why is high-quality steel plate used for the cabinet construction?
High-quality steel plate is selected for the cabinet to ensure structural robustness, resistance to mechanical stress, and long-term reliability even in harsh industrial environments. The steel construction also provides effective shielding and contributes to the overall safety of the enclosure.
