12kV Electrical 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

■ Normal use condition

● Ambient air temperature:maximum temperature+40 ℃, minimum temperature -15℃.

● Humidity condition:daily average relative humidity: ≤95, daily average vapor pressure shall not exceed 2.2Kpa;

Monthly average relative humidity: ≤90?, Monthly average vapor pressure shall not exceed 1.8Kpa

● Altitude:Below 3000m.

● Earthquake intensity:Lower than 8 degrees.

● The ambient ait shall not be polluted by distinctive corrosive ot conbustble gas, vaporetc.

● Places free of frequent excessive vibrations.

● The user shall negotiate with manufacturer if the equipment is used beyond the normal conditions described in GB3906.

■ Design featuers

● Switch gear structure plesse see to figurel.

● Entirely metal armored, assembly structure,  wide range of assembly schemes.

● The cabinet body adopts importes aluminized and galvanized sheet , which is prossed
