摘 要:闡述了永磁驅動機構和電磁斥力驅動機構的優缺點,提出一種永磁斥力組合驅動系統,該系統充分發揮兩種機構的優點,即把永磁驅動機構的穩定驅動力和電磁斥力驅動機構的快速響應時間有機結合起來,以期達到快速穩定的效果。經過樣機試驗驗證,永磁斥力組合驅動系統相比單純的永磁驅動機構能縮短1/3 的時間,特別適合于開距較大的斷路器。
關鍵詞:永磁驅動機構;電磁斥力機構;真空斷路器;渦流

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
