Design

All circuit-breakers series BP type BP2 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 core of the electromagnetic drive is connected with the circuit-breaker shaft via connecting links. The BP2 shaft is connected via insulating tie-rods with vacuum interrupters and when turning, it controls circuit-breaker position contacts for external auxiliary circuits. Plate-type pressing springs are installed in insulating tie-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. Control block schemes are realized by using PCBs housed in circuit-breakers series BP.

The vacuum circuit-breaker control block (scheme) is housed in the circuit-breaker frame. The control is carried out both by Ac and DC. The circuitry realised in the control block makes it possible to easily use circuit-breakers for all well-known common operations in circuits with spring drive and electromagnetic drive for all new and formerly manufactured complete switchgears (К-IIIu, К-XII, К-ХXVI, К-37, KRU2-10, К-59, К-104, КМ-1Ф, КU-10Ц, К-Х and others).
