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
m
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.
