Product Description
KYN61-40.5(Z) Indoor HV Vacuum Switchgear
Main charateristics
- The switchgear is as 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 requirement of "FIVE PREVENTION".The space of the cable compartment 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 compartment open.It conforms to GB3906-1990.DL404-1997 and refers to IEC-298 standard.
Applying ambient conditions
Ambient temperature: The max. temperature should below +40ºC.The average value n 24 hours should be no more than 35ºC. The min .temperature should above -10ºC.
The height above sea level should be no higher than 1000m.
Relative humidity: The average humidity of a day should be no more than 95%.The average humidity of a month should be no more than 90%.
Water vapour pressure: The average vapour pressure of a day should be more than 2.2kPa. The average vapour pressure of a month should be no more than 1.8kPa.
It should be used in the place where it is free from fire, explosion, serious fifth, chemical erosion and vibration.
