KYN61-40.5 Armored Central AC Metal-enclosed Switchgear

■Overview
KYN61-40.5(Z) type armored removable AC metal-enclosed switchgear (hereinafter referred to as switchgear) is an indoor power distribution unit with three-phase AC flow of 50 Hz and rated voltage of 40.5kV. As power plants, substations, industrial and mining enterprises to accept and distribute electrical energy, to control, protect and detect the circuit, Can also be used in places with frequent operations . The switchgear complies with GB/T11022-1999, GB3906--2006 and DL_404-1997.

■Main features
The structure of the cabinet is assembled, the circuit breaker adopts the floor-standing structure of the handcart; the new type of composite insulated vacuum circuit breaker is used, and the interchangeability is easy to replace; the screw nut propulsion mechanism is installed in the trolley frame. It can easily move the handcart and prevent misoperation and damage the propulsion structure. All operations can be carried out under the closed state of the door; the interlock between the main switch, the handcart and the switchgear door is forced by mechanical locking. "Five-proof" function; cable room is abundant, can connect multiple cables; fast grounding switch is used for grounding and circuit short-circuit; enclosure protection grade IP3X, handcart door open state, protection grade IP2X; product conforms to GB3906--2006 DL .404-1 997 and reference adopt the international IEC-298 standard.
