VIB-24 Series of Indoor High Voltage Vacuum Circuit Breaker
with Common Insulated Cylinder
General DescriptionVIB-24 series of Indoor High Voltage Vacuum Circuit Breaker with Common Insulated
Cylinder is threephase A.C.50Hz indoor power distribution equipment with the rated
voltage of 24KV.It's used for protecting and controlling the electrical equipment in the
fileds of industry & minning enterprise,power plants and substation.This type Vacuum
Circuit Breaker conforms to national standards and the stipulation of IEC standard,the
capability reaches grade of M2-E2-C2.The product adopt composite insulation way,spring charged operation and screw rod
push mechanism, with the characeristics of small volume,compact design and reliable
operation, it can easily match with the switchgear and meet the "Five Preventions"demands.This kind of Vacuum Circuit Breaker can be used for many kinds of switchgear like KYN28-24(GZS1),This series of products include:VCB truck,isolation truck and fuse truck etc.Applying ambient conditions1.Ambient temperature:-15ºC~+40ºC.2.Ambient 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%.3.Earthquake intensity:not exceed 8 degrees.4.Saturated vapour pressure:the average pressure of a day should be no more than 2.2kPa;the average pressure of a month should be no more than 1.8kPa.5.The height above sea level:1000m(besides the special requirements).6.It should be installed in the places without fire,explosion,serious filth,chemical erosion and violent vibration.Main Technical Specification| S.N | Name | Unit | Data |
