Electrical Switchgear Technical?Parameter

12kV?Switchgear?KYN28A-12

KYN28A-12??air-insulated??metal-clad??enclosed??switchgear??is??a??necessary??power??distribution?

?equipment??in??7.2~12kV??3-phase??AC50/60Hz??single??busbar??sectional??power??system.

??It??is??major??used??in??power??generator, ??substation, ??

factory??and??high??building??to??receive??and??distribute?electrical??power.??Also??it??is??used??to??control, ?

?protect??and??monitor??the??circuit.??The??switchgear?accords??with??the??standard??of??GB3906, ??DL/T404??and??so??on.

■Characteristic:

●??Completely??metal-clad??and??enclosed, ??prevent??the??accident??spreading.??

The??low??voltage??section??and??the??high??voltage??section??are??full??individual.?

●??The??protection??degree??with??the??door??closed??is??up??to??IP4X.?

?It??prevents??persons??and??outside??solid??approaching??the??live??part??and??withdrawable??part, ?

?ensuing??persons??safe??and??the??switchgear??operated??reliably.?

●??Install??and??maintain??conveniently??with??the??cable??compartment??enough??space.

●??The??interlocks??are??simple??and??reliable??and??prevent??maroperation??effectively.??

●??Equipped??with??advanced??relay-protecting??device??and??can??realize??the??power??system??automatically.

●??Full??assembled??structure, ??handsome??figure??and??high??precision??process.??

●??The??switchgear??installed??against??wall??is??maintained??in??the??front;??

double-side??maintenance??is??convenient??and??reliable.?

●??There??are??pressure??relief??passages??in??the??trolley??compartment, ?

?busbar??compartment??and??cable??compartment.??

Thus??ensure??persons??safely??and??prevent??accident??spreading??when??electrical??arc??occurs??due??to??fault
