Product Description

KYN61-40.5 (Z) armored removable AC metal-enclosed switchgear (hereinafter referred to as switchgear) is a three-phase AC 50Hz, rated voltage 40.5kV indoor complete power distribution device.
It is used to receive and distribute electric energy in power plants, substations and industrial and mining enterprises. It has functions such as control, protection and detection of circuits, and can also be used in places with frequent operations.
This switchgear complies with GB/T11022-1999, GB3906-1991 and DL404-1997 and other standards.
 

Main feature

Cabinet structure is of assembled type, the circuit breaker adopts floor type handcart structure;
Equipped with brand new composite insulated vacuum circuit breaker, is featured with good interchangeability, and is simple to change;
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;
All operations can be carried out when the cabinet door is closed;
Interlocking  among  the  main  switch,  handcart  and  switchgear  adopts  compulsory  mechanical  locking  mode,  meeting the"Five defenses " function;Cable chamber is large enough, it could connect multi cables;The fast earthing switch is used for earthing and circuit short-circuit;
Of protection of the enclosure is IP3X, and is IP2X when the door of handcart chamber is opened;
The product complies with GB3906-1991, DL404-1997 and refers to IEC-298.
