Product Description
VIB-12 Indoor High Voltage Vacuum Circuit BreakerGeneral Description
Explation of Product type
VIB-12
-τ τ- Vacuum Circuit Breaker series Rated voltage(kV)
of Longxiang Electrical Co.,Ltd.Main usage,applying ambient conditionsVIB type indoor high voltage vacuum circuit breaker(Hereinafter referred to as vacuum circuit breaker)are used for 12kv rated voltage and AC 50Hz indoor switch equipment components.The products meet standard of GB1984-2003HV AC Vacuum Circuit Breaker,JB3855-1996 3.6~40.5kV Indoor AC High Votage Vacuum Circuit Breaker,DL/T403-2000 Order Technical Condition of 12kV~40.5kV Vacuum Circuit Breaker and IEC62271-100:2001HV AC Vacuum Circuit Breaker,etc.Circuit breaker used as protection and control unit of power design in electric network and industrial and minning enterprises,can be used for situation of switching various types of load and frequent operation and repeated breaking shor circuit current.This type VCB uses new type operating mechanism of VCB.Embed vacuum interrupter and main circuit's components as a integration by adopting embedded pole of international brand for primary part,so as to protect vacuum interrupter from crash,dust and moist.It has good environment adaptability, so that reducing operation and maintenance cost greatly and realizing maintenance free of primary part and few maintenance of operating mechanism. The integrated design of operating mechanism and VCB body has passed type test.It has E2 level electrical endurance and M2 level mechanical endurance,used as fixed unit and also withdrawable unit by matching specialized push-in mechanism.The fixed type VCB can add corresponding interlock for matching fixed type switchgear of XGN2,GG1A and GGX type.Applying ambient conditions1.Ambient temperature:Max. Temperature:40ºC,and average temperature within24h should
no more than35ºC Min.2.Relative humidity:The average relative humidity daily:≤95% The average relative humidity monthly:≤90% The average vapour pressure daily:≤2.2kPa The average vapour pressure monthly:≤1.8kPa3.The height above sea level:≤2000m4.Earthquake intensity:not exceed 8 degrees.5.It should be installed in the place without fire,chemical erosion,explosion,vapour and salt spray.
