Product Description

Product Description

KYN61-40.5(Z) type alternating-current metal-clad and metal-enclosed withdrawable switchgear (hereinafter referred to as switchgear) is a indoor complete set of power distribution unit of three-phase AC50Hz and rated voltage of 40.5k V. Used for receiving and distributing the electric energy in power plants, transformer substations,mining and industrial enterprises, etc., it controls, protects and detects the circuits, also is applicable to frequent operation locations. This switchgear complies with GB/T11022-1999, GB3906-1991, DL404-1997 ,etc.

Features

1. Cabinet structure is of assembledtype, the circuit breaker adopts floor type handcart structure;
2. Equipped with brand new composite insulated vacuum circuit breaker, is featured with good interchangeability, and is simple to change;
3. The handcart frame is mounted with lead screw nut propelling mechanism, it is able to move the handcart easily, and prevent damage of propelling mechanism caused by misoperation;
4. All operations can be carried out when the cabinet door is closed;
6. Cable chamber is large enough, it could connect multi cables;
5. Interlocking among the man switch, handcart and switchgear adopts compulsory mechanical locking mode, meeting the "five preventions" function;
7. The fast earthing switch is used for earthing and circuit short-circuit;
8. of protec tion of the enclosure is IP3X, and is IP2X when the door of handcart chamber is opened;
9. The product complies with GB3906-1991, DL404-1997 and refers to IEC-298.
