KYN61-40.5(Z) type indoor HV vacuum switchgear (hereinafter called switchgear) is three-phase AC 50Hz indoor power distribution equipment with the rated voltage of 40.5kV. It is used for power reception and distribution of the power station, substation, mining and industrial enterprises for the control, protection and monitor of the circuits. It can be used in the fields where it is operated frequently . It conforms to GB/T11022-1999, GB3906-1991, and DL404-1997 standards.
Main characteristics of KYN61-40.5(Z) Switchgear:
1.The switchgear is assembly type. The circuit breaker is floor roll-out
2.Adopted new compound insulation, vacuum circuit breaker has the features of good interchange ability and easy replacement.
3.The truck shelf is equipped with lead-screw drive mechanism, which can move truck easily and prevent the mechanism be damaged from faulty operation.
4.All the operations can be done with the door shut.
5.All interlocks connecting with the main switch, truck and door of switchgear adopt compulsive mechanical lock and can meet the requirements of “FIVE PROVWNTION”.
6.The space of the cable compartment is abundant for the connection of several cables.
7.The instant earthing switch is used for earthing and short-circuiting of the circuit.
8.The degree of protection for the enclosure is IP3X. It is IP2X when the door of truck compartment open. It conforms to GB3906-1991, DL404-1997 and refers to IEC-298 standard.
