摘 要:闡述了永磁驅(qū)動(dòng)機(jī)構(gòu)和電磁斥力驅(qū)動(dòng)機(jī)構(gòu)的優(yōu)缺點(diǎn),提出一種永磁斥力組合驅(qū)動(dòng)系統(tǒng),該系統(tǒng)充分發(fā)揮兩種機(jī)構(gòu)的優(yōu)點(diǎn),即把永磁驅(qū)動(dòng)機(jī)構(gòu)的穩(wěn)定驅(qū)動(dòng)力和電磁斥力驅(qū)動(dòng)機(jī)構(gòu)的快速響應(yīng)時(shí)間有機(jī)結(jié)合起來,以期達(dá)到快速穩(wěn)定的效果。經(jīng)過樣機(jī)試驗(yàn)驗(yàn)證,永磁斥力組合驅(qū)動(dòng)系統(tǒng)相比單純的永磁驅(qū)動(dòng)機(jī)構(gòu)能縮短1/3 的時(shí)間,特別適合于開距較大的斷路器。

Abstract: In this paper the advantages and disadvantages of permanent magnet drive mechanism and electromagnetic repulsion drive mechanism are expounded, and a combined drive system of permanent magnet repulsion force is proposed. The system gives full play to the advantages of the two mechanisms, that is, the stable driving force of permanent magnet drive mechanism and the fast response time of electromagnetic repulsion force drive mechanism are organically combined, so as to achieve the effect of fast and stable. The prototype test results show that the combined drive system with permanent magnet repulsion force can shorten the time by one third compared with the simple permanent magnet drive mechanism, which is especially suitable for the circuit breaker with large opening distance.
Key words: permanent magnet drives mechanism; electromagnetic repulsion mechanism; vacuum circuit breaker; eddy current
