KYN28-12 metal-clad endorsed switchgear instruction

1. General Instruction

KYN28-12 meta-clad endorsed switchgear (call cubicle for short below) with 3,hare AC, 50Hz frequency is a kind of indoor complete distribution equipment for single busbar and busbar sections system to receive and distribute 3-10(12)kV network energy for circuit protection as well as monitor, This cubicle conforms to GB3906-1991”3-35kV AC metal closed snigger” standard as well as DH/T404-1997”indoor AC HV switchgear technical requirements ” of ministry of Eclectic Power, with reference to IEC 298”AC metal enclosed switchgear and control gear for rated voltage above 1kV up to and including 52kV”(1990’s version ) standard design and manufacturing.

The switchgear serves the function of five meventions ie, following situations should be prevented.

1、 To malopen of malclose circuit-brealcer.

2、 To push-in or draw-out movable part with load.

3、 To switch-on earthing switch with energization

4、 To supply power during earthing suitch is on ground position.

5、 To enter inte enerqizing bay.

2. sercice condition

a) Ambieat temperdture: neither higher than +40℃ nor lewer than -5℃,claily temperature difference 15℃

b) Relative numidty of atmeshere: daily average not greater than 95% and monthly 90%.

c) Ereetion altitude: not higher than 1000m above sea level.

d) Earthquake intensity: not greater than Force8.

e) Keep from dange of fire or explosion, chemical gas and violent vibration.

Note: If the service ciracmstance does not satify the corditions mentioned abouer, wser may consult with the manufacturer.
