SIEMENS 8BK81 Series Metal-Clad Withdrawable Switchgear, licensed to Zhebao Electrical
SUMMARY
8BK81(KYN18-12)metal-clad Withdrawable switchgear is suitable for 3-phase AC 50Hz, 7.2~12kV single
busbar and single busbar section system.Apply to distribute electricity power and implement system control,protection and supervision monitoring.The switchgear complies with the standards
IEC298,GB3906,DL404.
OPERATIONAL CONDITIONS
Ambient temperature: +40℃ to -10℃.Altitude:
1000m(max).Relative humidity: daily average less than 95%,monthly less than 90%.Shock of
earthquake: less than 8 magnitude.This product should not be used under conditions of fire,explosion,earthquake and chemicalcorrosion
environments.Note: Special condition and requirement, consult
with the manufacturer.
CHARACTERISTIC
All switching operations take place with high-voltage compartment doors closed.Electrical
switch position indication on panel front for circuit-breaker,earthing switch and truck position.Logical
interlocks prevent maloperation.Positively driven shutters protect against accidental contact with live parts.Standard
degree of protection IP4X against electric shock and ingress of solid foreign bodies.Operating
levers can only be inserted when the interlocking conditions are fulfilled.In this way,undue stress on the interlock mechanisms is avoided.The following operations can only take place when the
stated interlock conditions are fulfilled:Move the withdrawable part from the test position to the service position-High-voltage compartment door closed-VCB or VC
in the OPEN position-(Make-proof)earthing switch in the OPEN positionMove the
withdrawable part from the service position to the test position-VCB or VC in the OPEN positionOperate the
VCB or VC-Withdrawable part have been locked in the test position or the service position.Operate
