❓ Frequently Asked Questions
Q
What are the available positioning states for the mid-mounted cabinet's removable cart?
The removable cart supports four positioning states: working, testing, isolation, and removal. This modular approach enables flexible operation and simplifies maintenance without requiring full system shutdown.
Q
What compartments is the mid-mounted cabinet divided into?
The cabinet is divided into four isolated compartments: the busbar room, circuit breaker cart room, cable room, and instrument relay room. This separation ensures operational safety and effectively prevents fault escalation between zones.
Q
What is the rated current and short-circuit breaking capacity of this product?
The mid-mounted cabinet supports a rated current range of 1250A to 3150A and a short-circuit breaking capacity of 25kA to 40kA, making it suitable for demanding distribution network applications.
Q
What is the "five-prevention" locking mechanism?
The "five-prevention" (五防) locking mechanism is a comprehensive interlocking system designed to prevent five types of common misoperations in switchgear, such as closing or opening a circuit breaker under load, or accessing a live compartment. It is a critical safety feature of the mid-mounted cabinet.
Q
Does the mid-mounted cabinet support intelligent protection functions?
Yes. The cabinet offers optional integrated protection devices that enable intelligent measurement and protection, allowing it to meet the requirements of smart and automated modern distribution networks.
Q
What international standards does this mid-mounted cabinet comply with?
The product is designed in strict compliance with both domestic and international standards, including GB (Chinese National Standard) and IEC (International Electrotechnical Commission) standards, ensuring global compatibility and quality assurance.
