High voltage switchgear series


KYN61-40.5 Armored Removable Ac Metal Endlosed Switchgear (hereinater referred to as the switchgear) is a complete indoor distribution device witha three-phase alterating curent of 50Hz and a rated voltage of 40.5kv. As a power plant, substation, and industrial and mining enterprise receiving anddistributing electricithy, it has functions such as control, protection, and monitoring of circuits, and can also be used in frequently operated places. Thisswitchgear complies with standards such as GB3906-2006,GB/T11022-1999,and DL/T 404-2007.


The cabinet structure adopts an assembled type, and the circuit breaker adopts a handcart floor structure,Equipped with a brand new composite insulated vacuum circuit breaker, with the characteristics of good interchangeabilily and easy replacement,The handcart frame is equipped with a screw nut pushing mechanism, which can easily move the handcart and prevent accidental operation fromdamaging the pushing structure;

All operations can be carried out with the cabinet door closed;the interlocking between the main switch, handcart., and switch cabinet door adopts a mandatory mechanical locking method. meeting the "fiveprevention' function:

The cable room has ample space and can connect multiple cables;
Quick grounding switch is used for grounding and closing short circuit circuits;The shell protection level is lP3X, and when the handcart door is open, the protection level is lP2X:The product complies with GB3906-2006, DL/T 404-2007, and adopts international lEC298 standards as reference.
