Voltage Switchgear:


_{♦ KYN61 armoured removable AC metal enclosed switchgear (here-inafter rferred to as
equipment) is suitable for 40.5 kV three-phaseAC 50Hz single bus and single bus
subsection power system. ltismainly used in power plants, substations, industrial and
miningenterprises, high-rise buildings and other transformer and distribu-tion occasions
to receive and distribute energy, and to control thecircuit. Protection and monitoring.
♦ This product conforms to IEC60298, EC62271-200, lEC62271-1,GB3906, GB/T11022,
DL/T404 and other relevant abundantstandards, and has perfect "five defenses" interlocking
function.Applicability of the equipment is strong, configurable ZN85-40.5,SF1, SF2, HVX40,
FP-40.5, VD4-40.5, HD4-40.5, VYG.-40.5,VBG-40.5 circuit breakers and JN22 -40.5,
JN15-40.5 groundingswitches to meet the needs of different users.}

<sub>1.Ambient temperature: not higher than + 40C, not lower than-15
"C, and within 24 hours its average.Temperature is not higher than+35 degree&apos;
theequipment should be used to reduce capacitywhen exceeding the above ambient
temperature.
2. Relative humidity: the daily average is not more than 95%, and the monthly average
is not more than 90%.
3. Altitude: Usually the installation site is not more than 1000m above sea level.The
bureau shouldreduce its capacity in placeswith an elevation of 1000m.
4. The equipment should be installed without fire, explosion andviolent vibration.No
chemical corrosion and other serious dirtyplaces.
5. If the above conditions of use are not satisfied, they should besettled through
negotiation between the user and the manufacturer.



Service environment
1. Ambient air temperature: -5ºC+40ºCand the average temperature should not exceed
+35ºC in 24h.
2. Air condition: With clean air. Relative humidity should not exceed 50% at +40ºC.
Higher relative humidity is allowed at lower temperature. Ex. 90% at +20ºC. But in view
of the temperature change, it is possible that moderate dews will produce casually.
3. Altitude above sea level should not exceed 2000M.
4. The device is suitable to the transportation and store with following temperature
:-25ºC ~+55ºC, in short time (within 24h) it reaches +70ºC. Under the limiting temperature,
device should not sufferdamage that can[1]t recover, and it can works normally under
normal conditions.
5. If the above operating conditions not meet user's demand. Consult with manufactory.
6. Technical agreement should be signed additionally if the device is used for marine petrol
drilltaken platform and nuclear power station.</sub>
