Инструкции По Установке для Toshiba HV6FS-MLD

 

 

 

 
The Toshiba HV6FS-MLD vacuum circuit 
breaker described in this manual is suitable for 
use on systems of 4.8kV and 7.2kV voltage 
classes that require interrupting ratings of 16kA 
and 14kA respectively and a continuous current 
rating of 630A.  The circuit breaker is intended 
for use in limited applications requiring small 
physical size and low maintenance. 
 
This breaker is designed for drawout operation 
using the H6A-HLS cell.  The H6A-HLS cell 
allows the circuit breaker to be withdrawn for 
service without requiring manual disconnection 
of line, load and control wiring. 
 
The circuit breaker is a motor-operated type.  
The motor is used to charge the closing springs 
and to close the breaker upon command.  The 
circuit breaker can be tripped electrically. 
 
Arc interruption is accomplished inside sealed 
vacuum interrupters mounted on track-resistant 
insulators.  Vacuum interrupters use low-surge 
contact materials that exhibit low current 
chopping levels reducing switching overvoltages. 
 
Fig. 1 and Fig. 2 illustrate and identify the major 
components of the circuit breaker and cell.
