FAQ

Frequently Asked Questions

Q1: What is a metal‑clad withdrawable switchgear? What are its main featuresA: A metal‑clad withdrawable switchgear (such as the KYN series) is a fully enclosed, fully compartmentalised power distribution device. Its distinctive feature is that the busbar compartment, circuit breaker compartment, cable compartment, and instrument compartment are independently separated from each other, with each compartment using metal partitions that are grounded and shielded. The core advantages are: the withdrawable circuit breaker trolley can be flexibly pulled out, facilitating online inspection, maintenance, or rapid replacement, which greatly reduces outage time

Q2: What is the "five‑prevention interlocking" function of a switchgear, and why is it importantA: The "five‑prevention interlocking" is a mandatory mechanical or electrical interlocking device that ensures operator safety and reliable equipment operation. It includes:
Preventing incorrect opening or closing of the circuit breaker;
Preventing opening or closing of the Disconnector (ie., the trolley) under load;
Preventing the closing of the earthing switch when the equipment is live;
Preventing the closing of the circuit breaker when the earthing switch is closed (ie., with an earth connection);
This design physically eliminates the possibility of human mis-operation and is a core requirement of electrical safety regulations

Q3: How do I choose between fixed‑type and withdrawable (trolley‑type) switchgear based on project requirementsA: The choice mainly depends on the requirements for power supply reliability and maintenance efficiency
Withdrawable type (eg., KYN series): Recommended for critical loads, applications requiring frequent operation, or scenarios demanding rapid fault recovery (such as large factories and data centres). The circuit breaker trolley can be kept as spare inventory; in case of a fault, it can be directly replaced as a whole, restoring power very quickly
Fixed type (eg., GGD, XGN series): Suitable for applications with stable loads and less stringent outage time requirements (such as general building power distribution). They have a simpler structure and relatively lower cost, but maintenance typically requires an overall busbar outage
