KYN61C-40.5 armored type removable AC metal-enclosed switchgear cabinet

KYN61-40.5 switchgear is a three-phase AC 50Hz, rated voltage 40.5kV indoor complete power distribution device, used for receiving and distributing electric energy in power plants, substations and industrial and mining enterprises, and has the functions of controlling, protecting and monitoring circuits, etc. Function.

Structure Description

The switchgear is designed according to GB3906 and IEC62271-200:2003 standards.The whole is composed of a cabinet and extractable parts (handcart). The cabinet structure is assembled with aluminum-zinc coated or galvanized sheets connected by bolts. The switch cabinet is divided into a circuit breaker room, a busbar room, a cable room and an instrument room. , All metal components are reliably grounded, each compartment of the main circuit system has an independent pressure release channel, and a 10x60mm grounding busbar can be set in the cable room.

main feature

1. The cabinet structure adopts assembled type, and the circuit breaker adopts handcart floor structure;

2. Optional: domestically designed vacuum circuit breaker ZN85-40.5 (3AV3), Xiamen Huadian solid-sealed vacuum circuit breaker VEP-40.5, Areva SF6 circuit breaker FP4025D, Schneider SF6 circuit breaker SF2, similar circuit breakers have mutual 3. The handcart frame is equipped with a screw nut propulsion mechanism and an overrunning clutch, which can easily move the handcart and prevent damage to the propulsion mechanism due to misoperation;

4. The interlocking between the grounding switch, the handcart and the switch cabinet door adopts a mandatory mechanical locking method, which meets the 'five defenses' interlocking function;

5. All operations can be carried out with the cabinet door closed to ensure the safety of operators;

6. The cable room has ample space, which can connect multiple cables and lead out overhead;

7. The protection level of the shell is IP3X, and the protection level of the door of the handcart room and each compartment is IP2X;

8. The material can be made of galvanized sheet or aluminum-zinc coated sheet.
