VS1-24 24KV INDOOR VACUUM CIRCUIT BREAKER(24KV VCB)

General Introduction

VS1-24 indoor high-voltage vacuum circuit breaker is an AC three-phase 50HZ indoor high-voltage switching equipment with rated voltage of 24KV,mainly applied for protection and control in power distribution system of power plant,electric substation and industrial and mining enterprise,It is especially applied for breaking of important load and place requiring frequent operation.The manufacture of circuit breaker complies with GB1984-2003″AC High-Voltage Circuit Breaker”,JB3855-1966″Technical Conditions for Ordering 3.6-40.5KV Indoor Vacuum Circuit Breaker”of national standard and relative IEC standards.It Has reliable interlocking function.The operating mechanism of circuit breaker is spring energy storage type,which is either available for AC/DC energy storage operation or manual operation. The circuit breaker can also be equipped with permanent magnetic operating mechanism of long service life,its mechanical life can get to 100000 times,which is suitable for place with extremely frequent operation.The assembled structure design makes the circuit breaker can not only be used as a fixed unit but also as mid-cabinet unit when it is equipped with chassis.
