产品介绍


  I. Product introduction

 
Type vacuum circuit breaker FDVS1 (ZN63A) indoor vacuum circuit breaker (hereinafter referred to as circuit breaker) is 12 kV ac 50 hz, rated voltage of indoor switchgear components, products comply with GB1984-2003 ac high voltage circuit breaker, JB3855-1996 < 3.6 ~ 40.5 kV indoor ac high voltage vacuum circuit breaker ", DL4003 < 12 kV ~ 40.5 kV high-voltage vacuum circuit breaker order technical conditions ", etc. The provisions of the standard.
 
The circuit breaker adopts composite insulation method to meet the insulation requirements under normal operating conditions, and effectively reduce the volume of the circuit breaker, the overall layout is reasonable, beautiful, simple.
 
The circuit breaker adopts the operating mechanism and the circuit breaker itself, which can be operated by AC or DC, or manually.
 
The circuit breaker is divided into fixed type and handcart type. The handcart is equipped with a special propulsion mechanism, which can easily move the handcart inside the switch cabinet and meet the "five protection" functional requirements of the switch cabinet.
 
Wide range of application, can be installed in fixed switch cabinet, can also be used for moving mobile switch cabinet.
 
Second, the use environment
 
The upper limit of ambient temperature is +40℃, and the average value measured within 24 hours does not exceed 35℃, while the lower limit is -15℃
 
The altitude is not more than 1000m
 
Relative humidity: daily average does not exceed 95%, monthly average does not exceed 90%.
 
Water vapor pressure: daily average does not exceed 2.2kPa and monthly average does not exceed 1.8kPa.
 
The surrounding air is not visibly polluted by dust, smoke, corrosive or combustible gases, steam, and salt fog.
 
When the user exceeds the normal environment and other conditions specified in GB/T11022-1999
