classification

Classification by voltage level

According to the voltage level classification, AC1000V and below (such as PGL, GGD, GCK, GBD, MNS, etc.), AC1000V and above (such as GG-1A, XGN15, KYN48, etc.), and sometimes the voltage in the high voltage cabinet is AC10kV (such as XGN15 10kV ring network cabinet).

Classified by internal structure

Withdrawable cabinets (such as GCS, GCK, MNS, etc.), fixed cabinets (such as GGD, etc.)

Classified by use

Incoming cabinet, outgoing cabinet, measuring cabinet, compensation cabinet (capacitor cabinet), corner cabinet, busbar cabinet.

Five defenses

"Five defenses" for high-voltage switchgear

1. After the vacuum circuit breaker trolley in the high-voltage switchgear is closed at the test position, the trolley circuit breaker cannot enter the working position. (Prevents closing with load)

2. When the grounding knife in the high-voltage switchgear is closed, the trolley breaker cannot be closed. (Prevent closing with ground wire)

3. When the vacuum circuit breaker in the high-voltage switchgear is closed, the back door of the panel is locked with the machine on the grounding knife and the door. (Prevents the charging interval from being mistakenly entered).

4. The vacuum circuit breaker in the high-voltage switchgear is closed during operation, and the closing grounding knife cannot be turned on. (To prevent the ground wire from being charged)

5. When the vacuum circuit breaker in the high-voltage switchgear is closed, it cannot exit the working position of the trolley circuit breaker. (Prevent pull broach with load)
