Vacuum circuit-breakers series BP are ideally suitable for switching and protection operations in MV grids. Circuit-breakers series BP are used for switching loads of any types at rated currents of up to 3150 A and breaking currents of up to 40 kA. Circuit-breakers series BP are designed on the basis of the unified design concept, namely: using cast epoxy compound poles; using the versatile electromagnetic drive, which acts as a magnetic latch and is controlled by an electronic block housed in the circuit-breaker frame.

BP6 circuit-breakers can be used for replacement of circuit-breakers in complete switchgears type KG-6.

Specifications:

  • Rated voltage (kV): 6
  • Rated current (A): 1600, 2000
  • Rated breaking capacity (kA): 40
  • Peak withstand current (kA): 128
  • Mechanical lifetime: 30000 CO cycles
  • Electrical lifetime: 30000 CO cycles
  • Electrical lifetime at rated breaking current: up to 40 O cycles

Design

All circuit-breakers series BP type BP6 consist of three poles with vacuum interrupters filled with cast epoxy compound and mounted on the circuit-breaker frame. The circuit-breaker electromagnetic drive fixing circuit-breakers in C and O positions on magnetic latches is housed in the circuit-breaker frame. The BP6 shaft is connected via insulating rods with vacuum interrupters and when turning, it controls circuit-breaker position contacts for external auxiliary circuits. Plate-type pressing spring mechanisms are installed in insulating rod bushings. The local manual emergency switching-off of the circuit-breaker is actuated by a separate switching-off lever, which is common for all types of BP circuit-breakers.
