Truck Type Indoor High-voltage Vacuum Circuit Breaker
General Description
ZN39-40.5 type indoor HV vacuum breaker is used for many kinds of Switchgear like JYN1-35 and GBC-35.It is widely used for 40.5kV voltage systems is accordance with GB1984-2003 standards.
This series include:Vacuum circuit breaker truck,isolation truck and fuse truck.
Structural characteristics:
 1.This vacuum circuit breaker adopts compound insulation;it can meet air distance and creepage under normal run condition,and it effectively reduces the dimension of VCB,the overall arrangement is reasonable and simple,with aesthetic appearance.
 2.The operating mechanism is adopted CD10II electro-magnetic operating mechanism or CT19n spring operating mechanism,the outlet curve has good adaptation with requirements of vacuum interrupters.It has high reliable with characteristics of long life and easy maintenance.
 3.Easy pushing-in or pushing-out of panel for the truct,compulsive mechanical interlock way is adopted;meet the "Five Preventions"function;suitable for varies site and the working sites which have rigorous run condition.
 
Applying ambient conditions
 1.Ambient temperature:-15~+40ºC.
2.The height above sea level:≤1000m(besides the special requirements).
3.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%.
4.Saturated vapor 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.Earthquake intensity:not exceed 8 degrees.
6.It should be installed in the places without fire,explosion,serious filth, chemical erosion and violent vibration.
