The 24KV 1250A outdoor sf6 medium voltage circuit breaker is designed for controlling and protecting 24KV transmission and transformation systems, operating at 50Hz and suitable for outdoor use. Additionally, it can function as a connecting circuit breaker and an integrated opening and closing device. This circuit breaker employs an intelligent arc-quenching system based on thermal expansion and auxiliary blowing, paired with a CT10 spring operating mechanism. Furthermore, it meets the standards set by GB/T1984-2014 for AC high-voltage circuit breakers and adheres to the IEC62271-100:2001 international standard for high-voltage AC circuit breakers and control equipment.

Arc extinction and harmonic elimination cabinet During regular functioning, the microcomputer controller constantly monitors the voltage signal received from PT. Suppose the system experiences PT disconnection, single-phase metal grounding, or single-phase arc grounding. In that case, the auxiliary secondary open triangle voltage will promptly shift from a low to a high level. The microcomputer controller will then activate. It will determine the type and phase discrepancy based on the alteration in the PT secondary voltage
