摘要
提出了一种具有自检自复功能的电能表外置剩余电流动作断路器,并对自检自复原理及硬件设计进行了详细的分析。解决了传统产品剩余电流保护功能在实际应用中未必能定期检验的难点,同时提升了产品的安全性与可靠性。
The external residual current circuit breaker the for with the checking and self-restoring function is proposed.The principle and hardware design of checking and self-restoring are analyzed in detail.The difficulty that the residual current protection of traditional products may not be inspected regularly in practical application is solved,and the safety and reliability of products are improved.
