KYN61-40.5(Z) indoor high voltage vacuum switchgear
Main characteristicss
The switchgear is assembly type.The circuit breaker is floor
roll-out.
Adopted new compound insulation vacuum circuit breaker has the
features of good interchange ability and easy replacement.
The truck shelf is equipped with lead-screw drive mechanism, which
can move truck easily and prevent the mechanism be damaged from
faulty operation.
All the operations can be done with the door shut.
All interlocks connecting with the main switch,truck and door of
switchgear adopt compulsive mechanical lock and can meet the
requirements of "FIVE PREVENTION".
The space of the cable comparment is abundant for the connection of
several cables.
The instant earthing switch is used for earthing and
short-circuiting of the circuit .
The degree of protection for the enclosure is IP3X.It is IP2X when
the door of truck comparment open.It conforms to
GB3906-2006,DL404-2007 and refers to IEC-298 standard.
General description
KYN61-40.5(Z) type indoor HV vacuum switchgear(hereinafter called
switchgear) is three-phase AC 50Hz indoor power distribution
equipment with the rated range voltage of 40.5kV. It is used for
power reception and distribution of the power station,substation
mining and industrial enterprise for the control,protection and
monitor of the circuits, It can be used in the fields where it is
operated frequently. It confroms to GB/T11022-2011,GB3906-2006,and
DL404-2007 standards.
Applying ambient conditions
Ambient temperature:The max temperature should be +40ºC.The average
value in 24 hours should be no more than 35ºC,the min temperature
should be -10ºC.
The height above sealevel should be no higher than 1000m.
Relative humidity:daily average relative humidity≤95%,monthly
average relative humidity≤90%
Earthquake intensity:not exceed 8 degrees
Saturated vapour pressure:daily average value≤2.2kPa,monthly average value≤1.8kPa
It should be used in the place where it is free from
fire,explosion,serious filth,chemical erosion and violent
vibration.
