KYN61-40.5 Armoured Moving Type AC Metal Enclosed Switchgear

Product Overview
KYN61-40.5 Armored Removable AC Metal Enclosed Switchgear (hereinafter referred to as switchgear) is an indoor complete set of power distribution equipment with three-phase AC current of 50Hz and rated voltage of 40.5kV. As a power plant, substation, and industrial and mining enterprise that receives and distributes electrical energy, it plays a role in controlling, protecting, and monitoring circuits, and can also be used in places with frequent operations. This switchgear complies with GB3906-2006, GB/T11022-1999, DL/T404-2007 and other standards
Main features
The cabinet structure adopts an assembled type, and the circuit breaker adopts a handcart floor standing structure
Equipped with a brand new composite insulated vacuum circuit breaker, which has the characteristics of good interchangeability and easy replacement
The handcart frame is equipped with a screw nut propulsion mechanism, which can easily move the handcart and prevent damage to the propulsion structure due to misoperation
All operations can be performed with the cabinet door closed
The interlocking between the main switch, handcart, and switch cabinet door adopts a mandatory mechanical locking method to meet the "five prevention" 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 protection level of the shell is IP3X, and when the handcart door is open, the protection level is IP2X
The product complies with GB3906-2006, DL/T404-2007, and adopts the international IEC298 standard as a reference
